专题04 阅读理解（科普性说明文） 主题01 人与社会——环境保护 Passage 1 （25-26九年级上·贵州遵义·期中） A wetland (湿地) is an area where the land is covered by water most of the time. They form when water builds up because it can’t run away. This water can be rainfall, or from lakes, rivers or the sea. The wetlands can be very large or small. Wetlands are found all over the world but they need protection. February 2nd is World Wetlands Day. Its purpose is to draw people’s attention to the importance of wetlands for our earth. ①________ Wetlands are home to 40% of the world’s plant and animal species (物种).Not only are they important for wildlife, but they also help to slow down climate(气候)change and protect areas from bad weather. More than 1,000 million people all over the world depend on wetlands for their living. Businesses such as eco-farming (生态养殖) and tourism provide jobs for local communities. Besides, food grown in wetlands feeds more than half of the world’s people. ②________ Since 1970,more than a third of the world’s wetlands have disappeared. More and more people worry about this issue. One of the biggest troubles to wetlands is the development of the land to be used for building homes, factories or farms. This makes wetlands become smaller, so it’s more difficult for certain wildlife to live there. Another trouble is the plants and animals from somewhere else. They harm their new environment because they grow quickly. ③________ Luckily, many people know the importance of environmental protection, and laws have been passed to make sure wetlands can be protected. In 1971, a group of countries signed an agreement called the Convention on Wetlands (《湿地公约》), which suggested many methods to protect wetlands and use them in an environmentally friendly way. Wetlands are so valuable to our planet. Remember: To protect wetlands is to protect ourselves. 1．Where does the water for wetlands come from? A．Gardens. B．Rainfall. C．Tap water. 2．What does the underlined word “issue” mean? A．Reason. B．Beginning. C．Problem. 3．Which is the right order of the subtitles (小标题) of each paragraph? a. What troubles wetlands?    b. Why are wetlands important?    c. How can wetlands be protected? A．①—b②—a③—c B．①—b②—c③—a C．①—c②—a③—b 4．What’s the main idea of the passage? A．The trouble of the wetlands. B．Wetlands need to be protected. C．Know the Convention on Wetlands Passage 2 （25-26九年级上·贵州黔东南·期中）Long ago, in the icy north, there was a city called Icedale on floating (漂浮) ice islands. It was home to lots of polar bears. It was also a city with restaurants, hospitals, police stations, and more. Polar bears burned oil which was easy to get to provide energy for lights, heaters, and machines. No one thought that could harm the environment. Over time, strange (奇怪的) things happened. The sea level rose; there was less snowfall; and polar bears began wearing T-shirts instead of thick coats. But life still seemed normal—until one small ice island disappeared completely. “ What’s causing this?” everyone wondered. A scientist named Luma explained, “It’s the greenhouse effect. Burning oil produces carbon dioxide that traps (困住) heat around our city. This causes the ice to melt, and we’ll lose more and more ice. If we keep burning oil, Icedale will disappear, too.” The leaders decided to take action. Luma’s team worked together to come up with ways to use clean energy from the sun, wind and sea. Slowly, Icedale began to improve. All polar bears learned they must live in a way that was kind to nature to protect their home. 1．The first paragraph mainly tells us ________. A．Icedale’s ways to produce energy B．some basic facts about Icedale C．environmental problems in Icedale 2．What do the strange things refer to? ① Fewer snowy days.           ② More rainstorms. ③ Rise in the sea level.        ④ Polar bears’ choice for light clothes. ⑤ Polar bears’ action of moving away. A．①②③ B．②③⑤ C．①③④ 3．What does the underlined word “melt” mean? A．变形 B．融化 C．形成 4．What’s the best title for the story? A．The disappearing islands B．The ways to protect home C．How Icedale saved itself 主题02 人与社会——科学技术 Passage1 （25-26九年级上·贵州铜仁·期中） So far, China has successfully sent a large number of satellites (卫星) and spaceships into space. Space scientists have been greatly inspired (赋予灵感) by the old stories and ancient famous people when giving them names. Since thousands of years ago, Chinese people have dreamed of going to the moon. Chang’e Flies to the Moon is one of the most popular stories. As you can see, China’s first man-made satellite to circle around the moon was named Chang’e 1. More interestingly, the moon rover (巡视器) was named after the Jade Rabbit, who is the partner of Chang’e in the story. These old stories carry people’s best wishes and dreams. With the development of science and technology, our scientists have made them come true. Kua Fu Runs After the Sun is another story to show how much ancient Chinese people wanted to know about the unknown world. Now, Kua Fu is going with the scientists to “visit” the sun, because we have a space project called Kua Fu Mission. Besides the ancient stories, space scientists also get ideas from ancient famous people. For example, Mozi, an ancient scientist, discovered that light travels in a straight line over 2,000 years ago. His discovery made space study take a big step at that time. So, China’s first quantum (量子) science satellite was named Mozi, making China the first country in the world to achieve quantum communication between satellites and the ground. From such simple things as giving names to the satellites, we can see how great our traditional culture is and what influence it has on our modern science and technology. 1．What do we know about Chang’e 1 according to the passage? A．It moves around the moon. B．It “visits” the sun with the scientists. C．It is the world’s first man-made satellite. 2．How does the writer support his opinion in Paragraph 4? A．By listing numbers. B．By comparing facts. C．By giving an example. 3．Which is the right structure of the passage? (①=Paragraph 1 ②= Paragraph 2, ...) A． B． C． 4．What’s the writer’s main purpose of writing the passage? A．To spread the traditional Chinese culture. B．To introduce the achievements in our science and technology. C．To tell how traditional Chinese culture influences our space science. 主题03 人与社会——科普知识 Passage 1 （24-25九年级上·贵州安顺·期中）Do you like eating eggs? We can use eggs to cook lots of delicious dishes. However, it would be dangerous to eat bad eggs. They can cause some terrible health problems. It’s important for us to find bad eggs. Here are two ways. Smell Bad eggs have a terrible smell. You can break an egg and pour it into a bowl. If the egg smells bad, throw it away. Float (漂浮) test Before breaking the egg, we can use the floating way. Prepare a bowl of water and place the egg in it slowly. 1. If it lies at the bottom, it is a very fresh egg. 2. If it stands at the bottom, you have an old but safe egg to eat. 3. If it floats in the water, you can still eat the egg if you don’t mind the taste. 4. If it floats on the water, just throw the egg away. It has gone bad! 1．What does the writer think of finding bad eggs? A．Dangerous. B．Important. C．Terrible. 2．How can we tell if an egg is bad? A．By tasting it. B．By touching it. C．By floating it. 3．Peter got a stomachache after eating an egg this morning. Which egg might he eat? A． B． C． 4．This text is probably from a ________. A．letter B．notice C．textbook Passage2 （25-26九年级上·湖南株洲·期中）One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn’t want to waste food. She cuts off the moldy part and eats the rest. Do you dare to eat moldy food? Is it safe to do this? Mold (霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad and it’s not safe to eat. If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water. This allows mold to easily grow below its surface. Bacteria (细菌) can also grow along with it. Compared with soft food, it’s easier to remove mold from hard food. The mold can’t grow very deeply inside this kind of food. According to a study, you should cut about 2.5cm around and below the mold to remove it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away. Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they’re quite delicious as well. 1．According to the passage, what should you do if you find mold on a tomato? A．You can eat it directly. B．You should throw it away. C．You can eat the rest part. 2．What does the underlined word “remove” mean in Paragraph 3? A．去除 B．培植 C．保留 3．What can we learn about mold from the passage? A．We can’t eat moldy hard food. B．It grows more easily inside hard food. C．Penicillium can be quite useful. 4．What is the writer’s main purpose of writing the passage? A．To teach people how to use the mold. B．To call on people to stop wasting food. C．To tell people how to deal with moldy food. 主题01 人与社会——科普知识 Passage 1 （25-26九年级上·湖南邵阳·期中）Long long ago people got fire from lightning (闪电). But they had to keep the fire burning, for they couldn’t start it again if there was no lightning. Later, they found out hitting two pieces of stones together could make a spark (火花). The spark could fire dry leaves. In this way they could make the fire again if it went out. Then people also learned to make a fire by rubbing (摩擦). They made a hole on a piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got a fire. As years went by, people learned other ways to make a fire. Sometimes they used the heat from the sun. They held a piece of glass in the right way and made a piece of paper on fire. About two centuries ago, people began to make matches. Matches brought people a quick and easy way to make fires. Today matches are still being used, but people have more new ways to make fires. One of them is to use an electric fire starter. Of course an electric fire starter is much more expensive than a box of matches. But it is very useful not only in daily life but also in the production. 1．What can the spark do? A．Fire dry leaves. B．Burn anything. C．Fire wet leaves. 2．How many ways did people learn to make a fire? A．Four. B．Five. C．Six. 3．When did people begin to make matches? A．Since people began to use fire for cooking. B．About two hundred years ago. C．Since people used the heat from the sun. 4．From the text, we know that ________. A．people haven’t used matches since they had electric fire starters B．today there are only two ways to make fires C．electric fire starters are widely used Passage2 （25-26九年级上·湖南郴州·期中）We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons. Most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of the fish which is called “salmon” (鲑鱼). This fish is born in fresh water but it travels many miles to salt water. There it spends most of its life. When it is old, it returns to its birthplace. Then it gives birth and dies there. In the north of Europe, there is a kind of mice. They leave their mountain homes when their homes become too crowded. They move down to the low land. Sometimes they move all the way to the seaside and many of them are killed when they fall into the sea. Recently scientists have studied the migration of a special kind of lobsters (龙虾). Every year when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows where they go. So sometimes we know why animals move from one place to another but at other times we don’t. Maybe living things just like to travel. 1．How does the writer express his opinion? A．By asking questions. B．By giving examples. C．By making comparisons. 2．Where is “salmon” born? A．In salt water. B．In warm water. C．In fresh water. 3．What does the underlined word “migration” mean in paragraph 5? A．迁徙 B．繁殖 C．觅食 4．Which of the following is the best title for the passage? A．Animals’ Living Habits B．Why Do Animals Stay in One Place C．Animal Migration: Reasons and Examples Passage3 （25-26九年级上·湖南衡阳·期中）On January 20, 2025, a Chinese company named DeepSeek makes a new AI, DeepSeek-R1. This AI can solve math problems, write computer codes, and answer questions. And DeepSeek-R1 is very special. For example, it costs less money to build. The team uses only $5.58 million (cheaper than other AI). A study shows DeepSeek-R1 is the best, and it shows that smart ideas are better than big spending. DeepSeek-R1 is free to people. On its first day, over 19,000 computer experts (专家) in the world start using it. A German scientist says, “Using R1 for experiments (实验) costs only $10, but other AIs need $300.” Even a Meta scientist in the U. S. says, “This AI can change the world.” U. S. companies are now worried (担心). Meta wants to spend $65 billion more in AI research. Experts say China is an AI leader now. It means China is the best in AI now. A Nature report says R1 is the best, and it shows that great ideas are more important than expensive tools. A DeepSeek worker says, “We want everyone to use AI, not just the rich people.” With R1, China shows that great things come from new ideas and hard work, not just money. 1．What can DeepSeek-R1 do? A．Do math problems and sing songs. B．Work out math problems and write codes. C．Write computer codes and answer the phones. 2．Why is DeepSeek-R1 more special than other AIs? A．It is very expensive to build. B．It is free and costs less to make. C．It needs expensive computers to run. 3．What does the underlined word “leader” in paragraph 3 mean? A．助力者 B．传播者 C．领先者 4．What is the main idea of the passage? A．DeepSeek-R1: A Cheap AI. B．China’s AI Success: Great Ideas Count. C．AI Competition between China and the US. Passage4 （25-26九年级上·湖南湘西·期中）If you need to call your parents but your phone is not with you, can you remember their numbers? To remember 11 numbers is not difficult. However, because of the smartphone (智能手机), many of us are losing this ability, Record Japan reported. What’s more, smartphones weaken our skills at giving directions as well as killing face-to-face communications. Even when friends are having a meal together, it’s common for most of them to check their phones. According to a report by Kleiner Perkins Caufield Byers, an American company, Chinese people spend on average 170 minutes on their smartphones daily. For students, an addiction to smartphones does no good for studying. Research by Japan’s Education Ministry shows that children who spend more than four hours a day on their phones perform much worse in school tests than those who play with their phones for 30 minutes a day. It’s true that the smartphone has made our lives easier. But many also think they spend too much time on it, and this is bad for their study or work. People are trying to change that. A new app called Forest was introduced some time ago. It lets users plant a seed (种子) that grows into a tree over the next 30 minutes. During the half hour, users cannot use their phones, or the tree will die. A restaurant in Los Angeles, US, gives people a 5 percent discount (折扣) if they don’t check their phones during a meal. Owner Mark Gold said that he hoped it could give people a way to enjoy their meal and actually talk with friends and family in person. 1．Because of the smartphone, people ________. A．have less face-to-face communications B．can remember numbers better C．like to have meals together with friends 2．What does the app Forest aim to do? A．To introduce a new game. B．To call on people to care about trees. C．To help people spend less time on their phones. 3．The underlined word “addiction” probably means ________ in Chinese? A．购买 B．研究 C．沉溺 4．What does the article mainly talk about? A．The changes of smartphones. B．The advantages of smartphones. C．The disadvantages of smartphones. Passage5 （25-26九年级上·海南省直辖县级单位·期中）AI is shaking up the world now. It has been widely used in many different fields. The first field is about Chatbots (聊天机器人), a kind of AI-driven tool, have become a necessary part of modern communication. They can understand and reply to users at once. Whether it’s on websites or mobile apps, chatbots can offer support in real time. Besides, AI users can control smart home tools through voice orders. AI is reshaping (重塑) the way we communicate in our daily lives. The second field is the advantages of AI in transportation. For example, some ride-sharing platforms (拼车平台) depend heavily on AI. They use AI to match passengers with drivers and provide better transportation services. And self-driving cars are a main example of AI’s use in transportation, too. With the help of AI, they can reduce accidents and help those unable to drive. The third field is that AI provides a smart way for education. It changes the way teachers teach and students learn. AI in classrooms can make teaching and learning more interesting, which helps students focus more on their studies. AI can also offer students support outside classrooms. For example, it can help with homework, answer questions, and provide explanations. By analyzing (分析) students’ advantages, weaknesses and learning needs, AI can make suitable study plans for them. This can help students achieve their learning goals more easily. All in all, AI is shaping and will continue to shape our everyday experiences. 1．How many fields of AI are mentioned in this passage? A．Three B．Four C．Five 2．What does Paragraph 3 mainly talk about? A．Researches on AI in transportation. B．Problems of AI in transportation.

A．It takes a long time for chatbots to reply to users. B．Ride-sharing platforms hardly depend on AI. C．AI will continue to influence our daily lives. 5．Which of the following shows the structure (结构) of the passage? A． B． C． 主题02 人与社会——环境保护 Passage 1 （24-25九年级上·贵州铜仁·期中）At night, look up at the sky. How many stars do you see? If you live in the country, bright stars will fill the sky. If you live in the city, on the other hand, you might not see any stars. What’s happening? Bright lights from the city are lighting the sky, making the stars unseen. This is light pollution. Light can also come into city homes, like an uninvited guest. Sometimes, a visitor to a big city can’t sleep because of the bright signs outside his or her window. Darkness helps us sleep. Without darkness, we lie awake and can’t sleep, which may lead to serious health problems. Living things need darkness. It’s part of the natural 24-hour cycle. Trees and plants that are too close to artificial light grow in strange ways and die quickly. Animals become puzzled (困惑的) when light and dark are changed. For example, night animals might think it’s day when it’s night. Finally, using too many lights consumes (消耗) energy and money. The huge lights for all-night parking lots are too bright and unnecessary. Every city spends millions of dollars to light its thousands of buildings and streets, and much of this lighting is just to make the city look beautiful, rather than to serve a certain purpose. True, we feel safer in the light, but our eyes are able to see a little in darkness. And we don’t need to light the whole city just to create a beautiful night view. We should try to turn the lights off to save the earth and all the living things from light pollution. 1．Why can’t people see any stars in the city at night? A．The city has many high buildings. B．The living things in the city need darkness. C．The bright lights in the city make the stars unseen. 2．What does the underlined word “artificial” in Paragraph 3 probably mean? A．Man-made B．Medical. C．Wild. 3．What result may the light pollution bring? ①People may have health problems.   ②People can not see in the darkness.  ③Night animals may become puzzled. ④It consumes much energy and money. A．①②③ B．①③④ C．②③④ 4．What’s the best title for the passage? A．Living Things Need Darkness B．Let's Reduce Light Pollution C．How to Avoid Light Pollution Passage1 （25-26九年级上·海南海口·期中）It was 10:00 on a Wednesday night. Li Xiang, a 14-year-old student, sat at his desk worriedly. He had to write a 600-word book report and it must be handed in the next day. But he hadn’t read the book yet! Li opened a new AI app Deep Seek and typed in “Book report, The Old Man and the Sea.” In less than a minute, the boy had his book report. Several days later, Li was called into his teacher’s office. Unluckily, the teacher knew about computers and AI apps. And by using the Deep Seek, he explained that although AI apps were helpful for some tasks, there was no shortcut (捷径). Li finally knew how to use AI apps in a proper way. An AI app depends on a collection of information that someone has uploaded (上传) onto a computer system. A specially trained algorithm (算法) deals with the information to produce the type of writing someone might need. It may be useful for writing news reports, but it’s not useful for expressing your personal thoughts and ideas. Writing is the most difficult of all the language skills. You need to be good at grammar and have a good vocabulary. Writing also requires you to think clearly. If you read the book and write the book report by yourself, you will learn a lot and express your own ideas about the story better. That’s something AI cannot do. 1．What did Li Xiang do on the night of Wednesday? A．He was busy reading the book. B．He wrote his book report by himself. C．He got the 600-word report with the help of Deep Seek. 2．Which word can best describe Li Xiang’s teacher? A．Brave. B．Patient. C．Humorous. 3．An AI app can do the following EXCEPT ________. A．collecting information we upload B．producing the type of writing we need C．expressing our personal thoughts and ideas 4．In the last paragraph, the writer talks about the writing skills by ________. A．giving examples B．listing facts C．asking questions 5．What’s the best title for the passage? A．Deep Seek Makes a Magic World B．We Should Use AI Apps in a Proper Way C．AI Apps Help Students with Study Passage2 （25-26九年级上·四川成都·期中） Math is the study of numbers and how they relate to each other and the world. We need math for many things–for science, for building everything from houses to bridges, and for powering the computers and smartphones we use in our everyday lives. Numbers are everywhere in nature. Let’s explore two examples. A honeycomb is made up of hexagons. The six-sided shapes can fit together perfectly, allowing bees to save space and materials. Another example is the sunflower. Its seeds grow in special patterns. If you count them, you will often find numbers like 21, 34 or 55, where each new number is the sum (总和) of the two before it. This allows the sunflower to grow the most seeds in its center. The first people to count almost certainly used their hands and ten fingers to help, like children today. As a result, our modern counting system is based on tens. Nine Chapters is a famous ancient Chinese mathematics book. It was written about 2,000 years ago. This book is like a practical guidebook. It collects 246 problems on topics like farming, trade, and engineering. This book was a key math textbook in Asia for centuries. 1．Why does the writer give examples of the things that need math in everyday life? A．To show how important math is. B．To show how interesting math is. C．To show how difficult math is in daily life. 2．Why do we count in groups of ten according to the passage? A．Because it is easier to write. B．Because ten is common in life. C．Because people have ten fingers. 3．Which of the following is the right picture of a hexagon? A． B． C． 4．What question is NOT answered in the passage? A．Who wrote “Nine Chapters”? B．Why do the sunflower seeds grow in a special pattern? C．How many problems does “Nine Chapters” collect? 5．Where do you probably find the passage? A．A website about nature. B．A magazine about science. C．A guidebook about culture. Passage3 （25-26九年级上·四川成都·期中）You might notice that some foods are named after places—for example, Pu’er tea and Nanjing salted duck. These are the “birthplaces” of these foods. In fact, a product’s birthplace is very important. It’s about the quality. An agreement between China and European Union (EU) started to work in 2021. It listed the names of products and their birthplaces. They are called geographical indications (GIs, 地理标志). Which products can get GIs? Farm products, food, wine, handicrafts, and industrial products can get GIs. On the first GI list, there are food, farm products, wine and tea. On the next list, there would be some Chinese cultural products, such as Shu Embroidery (蜀绣) and Xuan paper. How many products are on the GI list? In 2023, two hundred products from China and EU countries were on the list. As planned, a new list would come out in 2025, and there would be 350 GIs by the end of that year. How will the agreement help us? It is good for both shoppers and companies. People can buy high-quality products based on the GIs. They don’t have to worry if they are fake. Companies can sell more products to other countries. Some products are only popular in China. Now they might become popular in Europe. This will also promote business between China and Europe. Look at some products on the GI listWuchuan mooncakes Wuchuan in Zhanjiang, Guangdong, is the birthplace of mooncakes. It has 39 national mooncake brands (品牌). Mooncakes there are large with thin wrappers (薄皮) and rich fillings. Each mooncake is as heavy as 3 kg. They have many kinds of tastes. Zhecheng hot peppersZhecheng county in Henan is famous for planting peppers. Each year, it sells more than 50,000 tons of hot peppers. Danish BlueIt is a kind of cheese from Denmark. It is made from cow’s milk. People make it in caves. You can see blue streaks (条纹) in it. It is creamy and tastes salty. 1．GIs help customers learn about the ________ of the products by connecting names with specific places. A．production techniques B．production place C．production process 2．Based on the passage, how many products will be added to the GI list between 2023 and 2025? A．150 B．200 C．350 3．Which of the following is most possible on the first GI list mentioned in the passage? A． B． C． 4．Which of the blanks can be filled in with the underlined word “fake”? A．This ________ notebook is popular among students because it is long-lasting and easy to write on. B．We should learn to tell real products from ________ ones to avoid being cheated.

B．Zhecheng county, famous for planting peppers, sells over 50,000 tons yearly. C．Pu’er tea, named after its birthplace, might be listed in the next GI list of cultural products along with Xuan paper. Passage4 （25-26九年级上·四川成都·期中）Could you imagine being in a car driven by a computer, not a human? Recently, China has made a big step toward self-driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen. Why do we develop self-driving cars? Self-driving cars have many advantages (优点). They use computers with many cameras which can sense all the objects close to the car and give the computers another route (路线). Then the car can take people to the places where they want to go. For disabled or blind people, self-driving cars can also help them get around more easily. According to US Centers for Disease Control and Prevention, each year, more than 1.35 million people are killed on roads around the world. It’s reported that self-driving cars could reduce road accidents by 90 percent. The main cause of car accidents is human error (错误). By using computers, self-driving cars don’t make poor decisions or lose attention like humans do. But self-driving cars aren’t perfect. If something unexpected on the road happens, self-driving cars can’t react (反应) as fast as a human driver can. Also, during weather events like heavy snow, self-driving cars wouldn’t see the lines on the road easily. It might lead to an accident. The car’s computer system would be broken by someone, causing it to crash or change its direction. It’s clear that there is a lot of work to do to make self-driving cars a common and safe sight on our roads. And China is taking the lead in making this happen. 1．In which cities can we see driverless taxis recently? A．Nanjing, Hangzhou and Suzhou. B．Wuhan, Chongqing and Shenzhen. C．Beijing, Shanghai and Guangzhou. 2．What is the main cause of car accidents according to the passage? A．Bad weather. B．Car trouble. C．Human error. 3．What is Paragraph 4 mainly about? A．The weaknesses of self-driving cars. B．Why human drivers are important. C．How to deal with traffic accidents. 4．What can we know from the passage? A．Self-driving cars have caused many problems. B．Self-driving cars are already commonly seen in the world. C．China is trying to make self-driving cars safer and more common. 5．In which part of a magazine can you read this passage? A．Culture. B．Travel. C．Science. Passage5 （25-26九年级上·四川成都·期中）This decade has seen incredible advances in Artificial Intelligence (AI). AI is now a big part of our daily lives, leaving many people excited, while others feel worried. From education to delivery, almost no industry has been left unchanged by AI. Students can practice English by talking with AI, and creating a video can now be as simple as typing a few sentences. However, AI is surely a double-edged sword. While it brings great convenience and helps us work faster, it also has downsides. It could widen the gap between the rich and the poor, making powerful organizations stronger. Many repetitive jobs are now done by robots, which makes it harder for low-skilled workers who depend on those jobs to make a living. Even a powerful tech leader like Elon Musk wanted to pause more powerful AI, but he couldn’t stop its progress. So, will AI turn out to be humanity’s greatest invention, or will it become a future nightmare? Perhaps our grandchildren will be the ones who find out the answer. Beyond this, AI is also creating new tools in healthcare, transportation, and entertainment. It helps doctors analyze medical images and powers self-driving cars. Yet, it also raises serious questions about data privacy and the future of work. The future depends on the decisions we make today. 1．How can students use AI? A．To make videos quickly. B．To deliver packages. C．To change any industry. 2．Which of the following picture can best describe “a repetitive job”? A． B． C． 3．What did Elon Musk want to do about powerful AI? A．Stop its development for a while. B．Make it even more powerful. C．Let grandchildren answer questions about it. 4．What can we infer from the passage about the future of AI? A．Its development is certain to create more problems than it solves. B．Its advantages are widely recognized though it has risks. C．Its progress can be easily controlled by human decisions. 5．Why did the author write this passage? A．To introduce the latest AI products from a company. B．To encourage people to think carefully about AI’s future. C．To tell a story about Elon Musk and AI. Passage6 （25-26九年级上·贵州贵阳·期中） Adult flamingos get their bright colors from the food they eat. But not all flamingos become the same color—pink. They can also become red, orange, or even white with pink, orange or red feathers mixed in. It all depends on the kinds of flamingos and the food in flamingos’ living places. All six kinds of flamingos live in different areas of the world. They usually stay in wetlands in different parts of the world. The food they eat has huge numbers of pigments (色素). When flamingos eat the food, the pigments are taken in and then left in their skin (皮肤), feathers and mouths. If flamingos aren’t able to eat enough food with these pigments, their colors may become less bright, and their feathers may also slowly lose colors because the strong sunlight in their living places shines on them. But some flamingos have the secret to making their feathers brightly colored. Some substances (油性物质) that make feathers bright are oily substances produced by themselves. The substance comes from the part near their tails. They reach back and apply the substance onto their skin and feathers. The more they apply, the brighter their skin and feathers will be! Being brightly colored is necessary because it helps flamingos look for mates. Also, different colors of flamingos look pretty cool. 1．What does the underlined word “They” in paragraph 1 refer to? A．The foods. B．The colors. C．The flamingos. 2．What may happen if flamingos don’t eat enough food with pigments? A．Their colors may become less bright. B．They may stop looking for mates. C．They may change their living places. 3．What’s the structure of the text?（P=paragraph） A． B． C． 4．What’s the text mainly about? A．Where Flamingos Live B．Why Flamingos Change Colors C．How Flamingos Find Their Food Passage7 （25-26九年级上·贵州铜仁·期中） We usually think that plants are quiet in the natural world. Grass doesn’t cry when you cut it. Flowers don’t scream when they’re picked. But our human view of the world misses quite a lot. Plants talk to each other all the time. Their language is chemical. Over the years, scientists have reported that different types of plants, from trees to tomatoes, release compounds (释放化合物) into the air to help neighboring plants. How plants receive and act on many of these signals (信号) is still mysterious. Recently, a team led by Junji Takabayashi of Japan’s Kyoto University has offered some explanations, as reported by Time magazine. The scientists looked at tomato plants bitten by insects. First, they grew plants in two plastic houses connected by a tube (管子). One plant was bitten by insects. The other was not. They found that when insects bite leaves, a plant doesn’t sit quietly. It releases a chemical called HexVic into the air. These chemicals carry a smell that neighboring plants can sense. People don’t notice it, though. This way, the neighboring plants understand the danger. They begin to make more HexVic to protect themselves. Later, scientists put insects on the other plants. The plants were able to kill about 50% of invaders (入侵者), much more than their sick neighbors. “It is surprising that plants don’t release a chemical until they get a warning message from their infested (受侵害的) neighbors,” scientists said. These findings may help farmers with pest control. 1．In Paragraph 1, the author (作者) leads in the topic by ________ . A．comparing things B．listing numbers C．giving examples 2．What is the correct order of the experiment process? a. About fifty percent of insects are dead. b. The neighboring plant smells the chemical. c. The plants are grown in two plastic houses. d. The plant bitten by insects releases a chemical. e. The plant starts to release more chemicals to protect itself. A．d-a-c-e-b B．c-d-b-e-a C．c-d-a-e-b 3．What is the correct structure of the passage? (P1=Paragraph 1) A． B． C． 4．What is the purpose of the passage? A．To show the relation between plants and insects. B．To show that plants have influences on each other. C．To explain how scientists do a biology experiment. Passage8 （25-26九年级上·贵州毕节·期中） Pandas are one of the most popular animals in the world, and they are China’s national treasure. Most pandas live in Sichuan, Shaanxi, and Gansu provinces of China. Pandas mainly eat bamboo. An adult panda eats about 12 to 38 kilograms of bamboo every day. They spend 10 to 16 hours eating because bamboo doesn’t have much nutrition (营养). Pandas have a special “sixth finger”—it’s not a real finger, but a part of their wrist. It helps them hold bamboo easily. Pandas are usually quiet and slow. They like to sleep in trees or on the ground. Baby pandas are very small when they are born—only about 100 grams, which is as light as a small apple. They are pink and have no hair. After about 6 months, they start to eat bamboo and grow black-and-white fur. Now, pandas are in danger. The number of bamboo forests is getting smaller because of human activities, so pandas lose their homes. Also, pandas have few babies—usually one or two every two years. To protect pandas, China has built many nature reserves (保护区) for them. Now, the number of pandas is increasing slowly. 1．Where do most pandas live in China? A．In Hubei, Hunan, and Jiangxi. B．In Sichuan, Shaanxi, and Gansu. C．In Guangdong, Guangxi, and Fujian. 2．Why do pandas spend so much time eating? A．Because bamboo is delicious. B．Because they have nothing else to do. C．Because bamboo has little nutrition. 3．What do baby pandas look like when they are born? A．Black and white. B．Pink and hairless. C．Small and furry. 4．What has China done to protect pandas? A．Built many nature reserves. B．Moved pandas to other countries. C．Fed pandas with other food. Passage9 （25-26九年级上·湖南湘西·期中） The Magic of Xiangxi’s Tea Deep in the mountains of Xiangxi, nature creates a perfect home for tea trees. This special environment gives the tea from this area a wonderful taste and smell, helping to create famous teas like Guzhang Maojian Tea, Berry Tea and Golden Tea. The tea culture here has a long history, with local people passing down traditional planting and picking methods from generation to generation. The high mountains here are often covered in thick clouds and mist. These clouds act like a soft blanket, protecting the young tea leaves from the strong sun. This allows the leaves to grow slowly and keep their fresh taste. What’s more, the air in Xiangxi is very clean and fresh. It is widely believed that the air quality here is exceptional, with very low levels of pollution. The forests are full of different plants, which make the soil rich and full of nutrients. When it rains, the water gets cleaned by the earth, reaching the tea trees in a pure state, This purity is another key to the tea’s quality. All these natural gifts work together like a team. They create a unique environment that cannot be easily found elsewhere. The tea trees grow happily in this balanced ecosystem, which teaches us an important lesson: when we protect nature and keep it in balance, it gives us its best gifts. This harmony between humans and nature is the true secret behind Xiangxi’s exceptional teas. 1．What is the main idea of the first paragraph? A．Xiangxi’s tea and its long history. B．The special taste of Xiangxi’s tea. C．The famous tea types in Xiangxi. 2．What does the underlined word “nutrients” in Paragraph 2 mean? A．Very small animals living in the soil. B．Water that comes from the mountains. C．Things that make plants grow strong and healthy. 3．Which of the following is NOT mentioned as a natural gift for Xiangxi’s tea? A．Clean air. B．Bright sunshine. C．Pure water. 4．According to the author, if your town wants to start a tea project (项目), what should you consider first? A．How to make the soil rich for the tea trees. B．How to use the local natural conditions in the best way. C．How to process tea while protecting the natural environment.

They form when water builds up because it can’t run away. This water can be rainfall, or from lakes, rivers or the sea. The wetlands can be very large or small. Wetlands are found all over the world but they need protection. February 2nd is World Wetlands Day. Its purpose is to draw people’s attention to the importance of wetlands for our earth. ①________ Wetlands are home to 40% of the world’s plant and animal species (物种).Not only are they important for wildlife, but they also help to slow down climate(气候)change and protect areas from bad weather. More than 1,000 million people all over the world depend on wetlands for their living. Businesses such as eco-farming (生态养殖) and tourism provide jobs for local communities. Besides, food grown in wetlands feeds more than half of the world’s people. ②________ Since 1970,more than a third of the world’s wetlands have disappeared. More and more people worry about this issue. One of the biggest troubles to wetlands is the development of the land to be used for building homes, factories or farms. This makes wetlands become smaller, so it’s more difficult for certain wildlife to live there. Another trouble is the plants and animals from somewhere else. They harm their new environment because they grow quickly. ③________ Luckily, many people know the importance of environmental protection, and laws have been passed to make sure wetlands can be protected. In 1971, a group of countries signed an agreement called the Convention on Wetlands (《湿地公约》), which suggested many methods to protect wetlands and use them in an environmentally friendly way. Wetlands are so valuable to our planet. Remember: To protect wetlands is to protect ourselves. 1．Where does the water for wetlands come from? A．Gardens. B．Rainfall. C．Tap water. 2．What does the underlined word “issue” mean? A．Reason. B．Beginning. C．Problem. 3．Which is the right order of the subtitles (小标题) of each paragraph? a. What troubles wetlands?    b. Why are wetlands important?    c. How can wetlands be protected? A．①—b②—a③—c B．①—b②—c③—a C．①—c②—a③—b 4．What’s the main idea of the passage? A．The trouble of the wetlands. B．Wetlands need to be protected. C．Know the Convention on Wetlands 【答案】1．B 2．C 3．A 4．B 【知识点】环境保护、说明文 【导语】本文主要介绍湿地的定义、水源，阐述湿地对生态、人类的重要作用，说明湿地面临的各类威胁，并介绍保护湿地的相关举措，点明保护湿地就是保护人类自身。 【详解】1．文中第一段提到“This water can be rainfall, or from lakes, rivers or the sea”，说明湿地水源包含降雨。 2．前文交代超三分之一湿地消失，人们为此担忧，由此可推断“issue”指代湿地消失这一难题，词义为“Problem”。 3．段落①介绍湿地价值，对应小标题b. Why are wetlands important?；段落②讲述湿地遭受的各类破坏，对应小标题a. What troubles wetlands?；段落③介绍保护湿地的法规与公约，对应小标题c. How can wetlands be protected?；顺序为①—b②—a③—c。 4．全文先介绍湿地价值，再讲现存危机，最后给出保护方案，核心主旨是湿地亟需保护。 Passage 2 （25-26九年级上·贵州黔东南·期中）Long ago, in the icy north, there was a city called Icedale on floating (漂浮) ice islands. It was home to lots of polar bears. It was also a city with restaurants, hospitals, police stations, and more. Polar bears burned oil which was easy to get to provide energy for lights, heaters, and machines. No one thought that could harm the environment. Over time, strange (奇怪的) things happened. The sea level rose; there was less snowfall; and polar bears began wearing T-shirts instead of thick coats. But life still seemed normal—until one small ice island disappeared completely. “ What’s causing this?” everyone wondered. A scientist named Luma explained, “It’s the greenhouse effect. Burning oil produces carbon dioxide that traps (困住) heat around our city. This causes the ice to melt, and we’ll lose more and more ice. If we keep burning oil, Icedale will disappear, too.” The leaders decided to take action. Luma’s team worked together to come up with ways to use clean energy from the sun, wind and sea. Slowly, Icedale began to improve. All polar bears learned they must live in a way that was kind to nature to protect their home. 1．The first paragraph mainly tells us ________. A．Icedale’s ways to produce energy B．some basic facts about Icedale C．environmental problems in Icedale 2．What do the strange things refer to? ① Fewer snowy days.           ② More rainstorms. ③ Rise in the sea level.        ④ Polar bears’ choice for light clothes. ⑤ Polar bears’ action of moving away. A．①②③ B．②③⑤ C．①③④ 3．What does the underlined word “melt” mean? A．变形 B．融化 C．形成 4．What’s the best title for the story? A．The disappearing islands B．The ways to protect home C．How Icedale saved itself 【答案】1．B 2．C 3．B 4．C 【知识点】环境保护、记叙文 【导语】本文是记叙文。主要讲述了北极浮冰岛上的冰谷市因燃烧石油产生温室效应导致环境恶化，最终通过改用清洁能源保护家园的故事。 1．主旨大意题。根据第一段内容，依次介绍了冰谷市的地理位置（北极浮冰岛）、居民（北极熊）、城市设施（餐厅、医院、警察局等）以及能源供应方式（燃烧石油），均为关于冰谷市的基础信息。故选B。 2．细节理解题。根据第二段“Over time, strange things happened. The sea level rose; there was less snowfall; and polar bears began wearing T-shirts instead of thick coats”可知，奇怪的现象包括海平面上升、降雪减少、北极熊穿T恤而非厚外套。对应①③④。故选C。 3．词义猜测题。根据前文“Burning oil produces carbon dioxide that traps heat around our city”可知，石油燃烧产生的二氧化碳会困住热量，结合冰谷市位于浮冰岛的背景，热量会导致冰“融化”。故选B。 4．最佳标题题。文章核心围绕冰谷市从因燃烧石油面临消失危机，到科学家提出改用清洁能源、最终改善环境的过程，重点是“冰谷市如何拯救自己”。故选C。 主题02 人与社会——科学技术 Passage1 （25-26九年级上·贵州铜仁·期中） So far, China has successfully sent a large number of satellites (卫星) and spaceships into space. Space scientists have been greatly inspired (赋予灵感) by the old stories and ancient famous people when giving them names. Since thousands of years ago, Chinese people have dreamed of going to the moon. Chang’e Flies to the Moon is one of the most popular stories. As you can see, China’s first man-made satellite to circle around the moon was named Chang’e 1. More interestingly, the moon rover (巡视器) was named after the Jade Rabbit, who is the partner of Chang’e in the story. These old stories carry people’s best wishes and dreams. With the development of science and technology, our scientists have made them come true. Kua Fu Runs After the Sun is another story to show how much ancient Chinese people wanted to know about the unknown world. Now, Kua Fu is going with the scientists to “visit” the sun, because we have a space project called Kua Fu Mission. Besides the ancient stories, space scientists also get ideas from ancient famous people. For example, Mozi, an ancient scientist, discovered that light travels in a straight line over 2,000 years ago. His discovery made space study take a big step at that time. So, China’s first quantum (量子) science satellite was named Mozi, making China the first country in the world to achieve quantum communication between satellites and the ground. From such simple things as giving names to the satellites, we can see how great our traditional culture is and what influence it has on our modern science and technology. 1．What do we know about Chang’e 1 according to the passage? A．It moves around the moon. B．It “visits” the sun with the scientists. C．It is the world’s first man-made satellite. 2．How does the writer support his opinion in Paragraph 4? A．By listing numbers. B．By comparing facts. C．By giving an example. 3．Which is the right structure of the passage? (①=Paragraph 1 ②= Paragraph 2, ...) A． B． C． 4．What’s the writer’s main purpose of writing the passage? A．To spread the traditional Chinese culture. B．To introduce the achievements in our science and technology. C．To tell how traditional Chinese culture influences our space science. 【答案】1．A 2．C 3．A 4．C 【知识点】科学技术、中华文化、说明文 【导语】本文主要介绍了嫦娥一号、“玉兔号”月球车、“墨子号” 空间量子科学实验卫星等与中国古代传统文化之间的渊源，表明了我国传统文化对太空技术的深远影响。 【详解】1．细节理解题。根据文章第二段“As you can see, China’s first man-made satellite to circle around the moon was named Chang’e 1.”可知，嫦娥一号绕月运行。故选A。 2．细节理解题。根据第四段“For example, Mozi, an ancient scientist, discovered that light travels in a straight line over 2,000 years ago. His discovery made space study take a big step at that time.”可知，在第四段中，作者通过举例子来支持自己的观点。故选C。 3．篇章结构题。通读全文可知，第一段介绍文章主题，太空技术与古代传统文化有关系；第二、三、四段分别从中国传统故事以及古代著名人物方面介绍；最后一段总结全文。故选A。 4．主旨大意题。根据“From such simple things as giving names to the satellites, we can see how great our traditional culture is and what influence it has on our modern science and technology.”及全文可知，作者写这篇文章的目的是介绍中国的空间技术与中国传统文化之间的渊源，中国传统文化影响着我国的空间技术。故选C。 主题03 人与社会——科普知识 Passage 1 （24-25九年级上·贵州安顺·期中）Do you like eating eggs?

It has gone bad!”可知，如果鸡蛋浮在水面上，就说明它变质了，所以不能吃这种鸡蛋。根据题意，皮特胃疼应该是吃了变质的鸡蛋。故选A。 4．推理判断题。通读全文可知，本文主要介绍了区分好鸡蛋和坏鸡蛋的方法，是一篇科普文，所以有可能来自一本课本。故选C。 Passage2 （25-26九年级上·湖南株洲·期中）One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn’t want to waste food. She cuts off the moldy part and eats the rest. Do you dare to eat moldy food? Is it safe to do this? Mold (霉菌) can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad and it’s not safe to eat. If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water. This allows mold to easily grow below its surface. Bacteria (细菌) can also grow along with it. Compared with soft food, it’s easier to remove mold from hard food. The mold can’t grow very deeply inside this kind of food. According to a study, you should cut about 2.5cm around and below the mold to remove it. It’s OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away. Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium (青霉菌) can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat and they’re quite delicious as well. 1．According to the passage, what should you do if you find mold on a tomato? A．You can eat it directly. B．You should throw it away. C．You can eat the rest part. 2．What does the underlined word “remove” mean in Paragraph 3? A．去除 B．培植 C．保留 3．What can we learn about mold from the passage? A．We can’t eat moldy hard food. B．It grows more easily inside hard food. C．Penicillium can be quite useful. 4．What is the writer’s main purpose of writing the passage? A．To teach people how to use the mold. B．To call on people to stop wasting food. C．To tell people how to deal with moldy food. 【答案】1．B 2．A 3．C 4．C 【知识点】科普知识、说明文 【导语】本文是一篇说明文。文章告诉我们霉菌的作用以及应当如何处理发霉的食物。 【详解】1．细节理解题。根据“If you find mold in soft food, just throw it away.”可知，西红柿是柔软的食物，而柔软的食物如果发霉了应该直接丢掉。故选B。 2．词句猜测题。根据“It’s OK to cut the moldy parts out of hard food and eat the rest.” 可知把硬食物上发霉的部分切掉，剩下的吃了也没关系。可推测出“remove”意为“去除”。故选A。 3．细节理解题。根据“But some kinds of mold can be used to make food. For example, penicillium can be used to make many types of cheeses, such as blue cheese.”可知，青霉菌可以用来制作各种奶酪，因此是有用的。故选C。 4．主旨大意题。通读全文可知，作者的写作意图是告诉人们如何处理发霉的食物。故选C。 主题01 人与社会——科普知识 Passage 1 （25-26九年级上·湖南邵阳·期中）Long long ago people got fire from lightning (闪电). But they had to keep the fire burning, for they couldn’t start it again if there was no lightning. Later, they found out hitting two pieces of stones together could make a spark (火花). The spark could fire dry leaves. In this way they could make the fire again if it went out. Then people also learned to make a fire by rubbing (摩擦). They made a hole on a piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got a fire. As years went by, people learned other ways to make a fire. Sometimes they used the heat from the sun. They held a piece of glass in the right way and made a piece of paper on fire. About two centuries ago, people began to make matches. Matches brought people a quick and easy way to make fires. Today matches are still being used, but people have more new ways to make fires. One of them is to use an electric fire starter. Of course an electric fire starter is much more expensive than a box of matches. But it is very useful not only in daily life but also in the production. 1．What can the spark do? A．Fire dry leaves. B．Burn anything. C．Fire wet leaves. 2．How many ways did people learn to make a fire? A．Four. B．Five. C．Six. 3．When did people begin to make matches? A．Since people began to use fire for cooking. B．About two hundred years ago. C．Since people used the heat from the sun. 4．From the text, we know that ________. A．people haven’t used matches since they had electric fire starters B．today there are only two ways to make fires C．electric fire starters are widely used 【答案】1．A 2．B 3．B 4．C 【知识点】科普知识、发明与创造、说明文 【导语】本文是一篇说明文，主要介绍了人类取火方式的发展历程，从最初的利用闪电到击石取火、钻木取火、利用太阳光，再到约两百年前发明的火柴以及现代的电动点火器。 【详解】1．第一段指出“The spark could fire dry leaves.”，说明火花可以点燃干树叶。 2．早期人们仅从闪电获取天然火，无法自行生火，不属于人类学会的人工生火方法；文中提及的人类学会的生火方法依次为击石取火、摩擦生火、利用太阳热量取火、火柴取火、电子点火器取火，共五种。 3．第三段指出“ About two centuries ago, people began to make matches.”，说明人们开始制造火柴是在大约两个世纪前，即约200年前。 4．第三段指出“Today matches are still being used”说明A项错误；根据“people have more new ways to make fires”说明B项错误；根据“it is very useful not only in daily life but also in the production”可推断电动点火器用途广泛，C项正确。 Passage2 （25-26九年级上·湖南郴州·期中）We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons. Most of them move to find food more easily, but others move to get away from places that are too crowded. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of the fish which is called “salmon” (鲑鱼). This fish is born in fresh water but it travels many miles to salt water. There it spends most of its life. When it is old, it returns to its birthplace. Then it gives birth and dies there. In the north of Europe, there is a kind of mice. They leave their mountain homes when their homes become too crowded. They move down to the low land. Sometimes they move all the way to the seaside and many of them are killed when they fall into the sea. Recently scientists have studied the migration of a special kind of lobsters (龙虾). Every year when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows where they go. So sometimes we know why animals move from one place to another but at other times we don’t. Maybe living things just like to travel. 1．How does the writer express his opinion? A．By asking questions. B．By giving examples. C．By making comparisons. 2．Where is “salmon” born? A．In salt water. B．In warm water. C．In fresh water. 3．What does the underlined word “migration” mean in paragraph 5? A．迁徙 B．繁殖 C．觅食 4．Which of the following is the best title for the passage? A．Animals’ Living Habits B．Why Do Animals Stay in One Place C．Animal Migration: Reasons and Examples 【答案】1．B 2．C 3．A 4．C 【知识点】科普知识、说明文 【导语】本文是一篇说明文，文章先点明动物会迁徙，介绍迁徙的两类原因（觅食、远离拥挤环境），再列举鸟类、鲑鱼、欧洲老鼠、龙虾的迁徙实例，最后说明部分动物迁徙原因尚不明确。 【详解】1．根据第3段“When cold weather comes, many birds...the migration of the fish which is called ‘salmon’”，第4段“In the north of Europe, there is a kind of mice.”和第5段“...the migration of a special kind of lobsters.”可知，作者通过列举鸟、鲑鱼、老鼠、龙虾这些例子来阐释观点，对应选项B。 2．原文第3段“...the fish which is called ‘salmon’. This fish is born in fresh water but it travels many miles to salt water.”直接点明，鲑鱼出生在淡水中，对应选项C。 3．根据首段“We know that many animals do not stay in one place...move from one place to another at a certain time.”和第5段“...the lobsters get into a long line and start to walk across the floor of the ocean.”可知，全文都在讲动物从一个地方移动到另一个地方（即迁徙），龙虾列队在海底移动也属于迁徙。因此，“migration”意为“迁徙”。 4．文章第1段引出动物移动的话题，第2段说明移动的原因，第3至5段列举了不同动物迁徙的具体例子，最后一段总结。选项C意为“动物迁徙：原因与示例”，最能准确概括全文内容。 Passage3 （25-26九年级上·湖南衡阳·期中）On January 20, 2025, a Chinese company named DeepSeek makes a new AI, DeepSeek-R1.

It means China is the best in AI now.”可知，DeepSeek-R1是最好的，中国目前在人工智能方面是最好的，所以“leader”在这里意思是“领先者”，表示中国在人工智能领域处于领先地位。故选C。 4．主旨大意题。文章主要介绍了中国公司推出的DeepSeek-R1人工智能，它成本低、功能强大且免费，体现了中国在人工智能领域的成功，并且强调了好的想法比大量的资金投入更重要。选项B“中国人工智能的成功：好的想法很重要”符合文章主旨。故选B。 Passage4 （25-26九年级上·湖南湘西·期中）If you need to call your parents but your phone is not with you, can you remember their numbers? To remember 11 numbers is not difficult. However, because of the smartphone (智能手机), many of us are losing this ability, Record Japan reported. What’s more, smartphones weaken our skills at giving directions as well as killing face-to-face communications. Even when friends are having a meal together, it’s common for most of them to check their phones. According to a report by Kleiner Perkins Caufield Byers, an American company, Chinese people spend on average 170 minutes on their smartphones daily. For students, an addiction to smartphones does no good for studying. Research by Japan’s Education Ministry shows that children who spend more than four hours a day on their phones perform much worse in school tests than those who play with their phones for 30 minutes a day. It’s true that the smartphone has made our lives easier. But many also think they spend too much time on it, and this is bad for their study or work. People are trying to change that. A new app called Forest was introduced some time ago. It lets users plant a seed (种子) that grows into a tree over the next 30 minutes. During the half hour, users cannot use their phones, or the tree will die. A restaurant in Los Angeles, US, gives people a 5 percent discount (折扣) if they don’t check their phones during a meal. Owner Mark Gold said that he hoped it could give people a way to enjoy their meal and actually talk with friends and family in person. 1．Because of the smartphone, people ________. A．have less face-to-face communications B．can remember numbers better C．like to have meals together with friends 2．What does the app Forest aim to do? A．To introduce a new game. B．To call on people to care about trees. C．To help people spend less time on their phones. 3．The underlined word “addiction” probably means ________ in Chinese? A．购买 B．研究 C．沉溺 4．What does the article mainly talk about? A．The changes of smartphones. B．The advantages of smartphones. C．The disadvantages of smartphones. 【答案】1．A 2．C 3．C 4．C 【知识点】说明文、网络的利弊 【导语】本文是一篇说明文，讲述了智能手机给人们生活带来便利的同时，也存在诸多弊端，如削弱面对面交流能力、影响学生学习等，还介绍了人们为改变过度使用手机状况所采取的措施。 1．文章第二段提到“What’s more, smartphones weaken our skills at giving directions as well as killing face-to-face communications.”，说明因为智能手机，人们面对面交流变少了。 2．文章第五段介绍“A new app called Forest was introduced some time ago. It lets users plant a seed (种子) that grows into a tree over the next 30 minutes. During the half hour, users cannot use their phones, or the tree will die.”，由此可知Forest应用旨在帮助人们减少使用手机的时间。 3．文章第三段提到“For students, an addiction to smartphones does no good for studying...children who spend more than four hours a day on their phones perform much worse in school tests...”，结合语境可知，学生过度使用手机对学习不利，每天花在手机上超过四小时的学生考试成绩更差，所以“addiction”意思是“沉溺”。 4．文章第二段指出“What’s more, smartphones weaken our skills at giving directions as well as killing face-to-face communications.”，第三段提到“For students, an addiction to smartphones does no good for studying.”，说明智能手机存在削弱面对面交流能力、影响学生学习等弊端，整篇文章主要围绕智能手机的缺点展开。 Passage5 （25-26九年级上·海南省直辖县级单位·期中）AI is shaking up the world now. It has been widely used in many different fields. The first field is about Chatbots (聊天机器人), a kind of AI-driven tool, have become a necessary part of modern communication. They can understand and reply to users at once. Whether it’s on websites or mobile apps, chatbots can offer support in real time. Besides, AI users can control smart home tools through voice orders. AI is reshaping (重塑) the way we communicate in our daily lives. The second field is the advantages of AI in transportation. For example, some ride-sharing platforms (拼车平台) depend heavily on AI. They use AI to match passengers with drivers and provide better transportation services. And self-driving cars are a main example of AI’s use in transportation, too. With the help of AI, they can reduce accidents and help those unable to drive. The third field is that AI provides a smart way for education. It changes the way teachers teach and students learn. AI in classrooms can make teaching and learning more interesting, which helps students focus more on their studies. AI can also offer students support outside classrooms. For example, it can help with homework, answer questions, and provide explanations. By analyzing (分析) students’ advantages, weaknesses and learning needs, AI can make suitable study plans for them. This can help students achieve their learning goals more easily. All in all, AI is shaping and will continue to shape our everyday experiences. 1．How many fields of AI are mentioned in this passage? A．Three B．Four C．Five 2．What does Paragraph 3 mainly talk about? A．Researches on AI in transportation. B．Problems of AI in transportation. C．Advantages of AI in transportation. 3．What does the underlined word “suitable” in Paragraph 4 mean? A．polite. B．proper. C．coming. 4．What can we probably infer (推断) from the passage? A．It takes a long time for chatbots to reply to users. B．Ride-sharing platforms hardly depend on AI. C．AI will continue to influence our daily lives. 5．Which of the following shows the structure (结构) of the passage? A． B． C． 【答案】1．A 2．C 3．B 4．C 5．A 【知识点】科学技术、说明文 【导语】本文介绍了人工智能在不同领域的应用，包括聊天机器人、交通、教育三个方面，阐述了AI对日常生活的重塑与持续影响。 1．根据第二段“The first field is about Chatbots”、第三段“The second field is the advantages of AI in transportation.”、第四段“ The third field is that AI provides a smart way for education.”文章分别从聊天机器人、交通、教育三个领域介绍了AI的应用，因此文中提到了三个AI领域。 2．第三段首句点明：“The second field is the advantages of AI in transportation.”，直接说明该段主要讲述AI在交通领域的优势。 3．第四段提到：“By analyzing students’ advantages, weaknesses and learning needs, AI can make suitable study plans for them.”，因此“suitable”指的是根据学生情况制定合适的学习计划，与“proper（合适的）”语意最接近。 4．最后一段指出：“All in all, AI is shaping and will continue to shape our everyday experiences.”，由此可推断出AI将继续影响我们的日常生活。 5．文章首段总起点明AI在多领域应用，第2-4段分别介绍三个具体领域，最后一段总结全文，结构为总-分-总，对应选项A的结构。 主题02 人与社会——环境保护 Passage 1 （24-25九年级上·贵州铜仁·期中）At night, look up at the sky. How many stars do you see? If you live in the country, bright stars will fill the sky. If you live in the city, on the other hand, you might not see any stars. What’s happening? Bright lights from the city are lighting the sky, making the stars unseen. This is light pollution. Light can also come into city homes, like an uninvited guest. Sometimes, a visitor to a big city can’t sleep because of the bright signs outside his or her window. Darkness helps us sleep. Without darkness, we lie awake and can’t sleep, which may lead to serious health problems. Living things need darkness. It’s part of the natural 24-hour cycle. Trees and plants that are too close to artificial light grow in strange ways and die quickly. Animals become puzzled (困惑的) when light and dark are changed. For example, night animals might think it’s day when it’s night. Finally, using too many lights consumes (消耗) energy and money. The huge lights for all-night parking lots are too bright and unnecessary. Every city spends millions of dollars to light its thousands of buildings and streets, and much of this lighting is just to make the city look beautiful, rather than to serve a certain purpose. True, we feel safer in the light, but our eyes are able to see a little in darkness. And we don’t need to light the whole city just to create a beautiful night view. We should try to turn the lights off to save the earth and all the living things from light pollution. 1．Why can’t people see any stars in the city at night? A．The city has many high buildings. B．The living things in the city need darkness. C．The bright lights in the city make the stars unseen. 2．What does the underlined word “artificial” in Paragraph 3 probably mean? A．Man-made B．Medical. C．Wild. 3．What result may the light pollution bring? ①People may have health problems.   ②People can not see in the darkness.  ③Night animals may become puzzled. ④It consumes much energy and money. A．①②③ B．①③④ C．②③④ 4．What’s the best title for the passage? A．Living Things Need Darkness B．Let's Reduce Light Pollution C．How to Avoid Light Pollution 【答案】1．C 2．A 3．B 4．B 【知识点】环境污染、说明文 【导语】本文是一篇说明文，主要介绍了光污染的问题。 【详解】1．细节理解题。根据“If you live in the city, on the other hand, you might not see any stars. What’s happening? Bright lights from the city are lighting the sky, making the stars unseen. ”可知，是因为城市里明亮的灯光让星星看不见。故选C。 2．词句猜测题。根据“Living things need darkness. It’s part of the natural 24-hour cycle. Trees and plants that are too close to artificial light grow in strange ways and die quickly.”可知，距离人造光太近的树木和植物会以奇怪的方式生长并很快死亡，此处指的是晚上的人造光源。故选A。 3．细节理解题。根据第二段“Without darkness, we lie awake and can’t sleep, which may lead to serious health problems.”、第三段“Animals become puzzled (困惑的) when light and dark are changed. ”以及第四段“Finally, using too many lights consumes (消耗) energy and money.”可知，①③④是光污染的后果。故选B。 4．最佳标题题。根据“We should try to turn the lights off to save the earth and all the living things from light pollution.”可知，作者介绍光污染，目的是呼吁人们做点什么来减少光污染。故选B。 Passage1 （25-26九年级上·海南海口·期中）It was 10:00 on a Wednesday night. Li Xiang, a 14-year-old student, sat at his desk worriedly. He had to write a 600-word book report and it must be handed in the next day. But he hadn’t read the book yet! Li opened a new AI app Deep Seek and typed in “Book report, The Old Man and the Sea.” In less than a minute, the boy had his book report. Several days later, Li was called into his teacher’s office. Unluckily, the teacher knew about computers and AI apps. And by using the Deep Seek, he explained that although AI apps were helpful for some tasks, there was no shortcut (捷径). Li finally knew how to use AI apps in a proper way. An AI app depends on a collection of information that someone has uploaded (上传) onto a computer system. A specially trained algorithm (算法) deals with the information to produce the type of writing someone might need. It may be useful for writing news reports, but it’s not useful for expressing your personal thoughts and ideas. Writing is the most difficult of all the language skills. You need to be good at grammar and have a good vocabulary. Writing also requires you to think clearly. If you read the book and write the book report by yourself, you will learn a lot and express your own ideas about the story better. That’s something AI cannot do. 1．What did Li Xiang do on the night of Wednesday? A．He was busy reading the book. B．He wrote his book report by himself. C．He got the 600-word report with the help of Deep Seek. 2．Which word can best describe Li Xiang’s teacher? A．Brave. B．Patient. C．Humorous. 3．An AI app can do the following EXCEPT ________. A．collecting information we upload B．producing the type of writing we need C．expressing our personal thoughts and ideas 4．In the last paragraph, the writer talks about the writing skills by ________.

Unluckily, the teacher knew about computers and AI apps. And by using the Deep Seek, he explained that although AI apps were helpful for some tasks, there was no shortcut.”可知，老师知道李想使用了AI应用，并耐心地解释了AI应用的利弊，由此可推断老师是有耐心的。故选B。 3．细节理解题。根据文章第三段“It may be useful for writing news reports, but it’s not useful for expressing your personal thoughts and ideas.”可知，AI应用不能表达我们的个人想法和观点。故选C。 4．推理判断题。根据文章最后一段“Writing is the most difficult of all the language skills. You need to be good at grammar and have a good vocabulary. Writing also requires you to think clearly.”可知，作者通过列举事实来谈论写作技能。故选B。 5．最佳标题题。根据文章第二段“And by using the Deep Seek, he explained that although AI apps were helpful for some tasks, there was no shortcut. Li finally knew how to use AI apps in a proper way.”以及全文内容可知，文章主要讲述了李想使用AI应用完成读书报告的经历以及老师的教导，强调了正确使用AI应用的重要性。故选B。 Passage2 （25-26九年级上·四川成都·期中） Math is the study of numbers and how they relate to each other and the world. We need math for many things–for science, for building everything from houses to bridges, and for powering the computers and smartphones we use in our everyday lives. Numbers are everywhere in nature. Let’s explore two examples. A honeycomb is made up of hexagons. The six-sided shapes can fit together perfectly, allowing bees to save space and materials. Another example is the sunflower. Its seeds grow in special patterns. If you count them, you will often find numbers like 21, 34 or 55, where each new number is the sum (总和) of the two before it. This allows the sunflower to grow the most seeds in its center. The first people to count almost certainly used their hands and ten fingers to help, like children today. As a result, our modern counting system is based on tens. Nine Chapters is a famous ancient Chinese mathematics book. It was written about 2,000 years ago. This book is like a practical guidebook. It collects 246 problems on topics like farming, trade, and engineering. This book was a key math textbook in Asia for centuries. 1．Why does the writer give examples of the things that need math in everyday life? A．To show how important math is. B．To show how interesting math is. C．To show how difficult math is in daily life. 2．Why do we count in groups of ten according to the passage? A．Because it is easier to write. B．Because ten is common in life. C．Because people have ten fingers. 3．Which of the following is the right picture of a hexagon? A． B． C． 4．What question is NOT answered in the passage? A．Who wrote “Nine Chapters”? B．Why do the sunflower seeds grow in a special pattern? C．How many problems does “Nine Chapters” collect? 5．Where do you probably find the passage? A．A website about nature. B．A magazine about science. C．A guidebook about culture. 【答案】1．A 2．C 3．B 4．A 5．B 【知识点】科普知识、说明文 【导语】本文是一篇说明文，主要介绍了数学在自然界和日常生活中的应用，包括蜂巢的六边形结构、向日葵种子数列、十进制计数法的由来以及中国古代数学著作《九章算术》，展现了数学与世界的紧密联系。 【详解】1．根据第一段中“We need math for many things—for science, for building everything from houses to bridges, and for powering the computers and smartphones we use in our everyday lives”可知，作者列举科学、建造房屋桥梁、电脑智能手机等例子，意在说明数学在日常生活中的重要性。 2．根据“Counting in ten”部分中“The first people to count almost certainly used their hands and ten fingers to help, like children today. As a result, our modern counting system is based on tens.”可知，人们以十为组计数是因为人有十根手指，这是最初计数的依据。 3．根据“Numbers in nature”部分中“A honeycomb is made up of hexagons.The six-sided shapes can fit together perfectly, allowing bees to save space and materials. ”可知，hexagon（六边形）由six-sided shapes描述，对比三个图形选项，B选项是六边形。 4．根据“Mathatics in ancient China”部分中“ It was written about 2,000 years ago.”可知，文中未提及《九章算术》的作者；根据“Numbers in nature”部分中“ Its seeds grow in special patterns...This allows the sunflower to grow the most seeds in its center.”可知，解释了向日葵种子特殊排列的原因；根据“Mathatics in ancient China”部分中“It collects 246 problems on topics like farming, trade, and engineering. ”可知《九章算术》收集的问题数量。 5．文章介绍了数学在自然界中的应用（蜂巢、向日葵）、计数方法及中国古代数学成就，涵盖了科学、文化等领域，最可能出现在科学杂志中。 Passage3 （25-26九年级上·四川成都·期中）You might notice that some foods are named after places—for example, Pu’er tea and Nanjing salted duck. These are the “birthplaces” of these foods. In fact, a product’s birthplace is very important. It’s about the quality. An agreement between China and European Union (EU) started to work in 2021. It listed the names of products and their birthplaces. They are called geographical indications (GIs, 地理标志). Which products can get GIs? Farm products, food, wine, handicrafts, and industrial products can get GIs. On the first GI list, there are food, farm products, wine and tea. On the next list, there would be some Chinese cultural products, such as Shu Embroidery (蜀绣) and Xuan paper. How many products are on the GI list? In 2023, two hundred products from China and EU countries were on the list. As planned, a new list would come out in 2025, and there would be 350 GIs by the end of that year. How will the agreement help us? It is good for both shoppers and companies. People can buy high-quality products based on the GIs. They don’t have to worry if they are fake. Companies can sell more products to other countries. Some products are only popular in China. Now they might become popular in Europe. This will also promote business between China and Europe. Look at some products on the GI listWuchuan mooncakes Wuchuan in Zhanjiang, Guangdong, is the birthplace of mooncakes. It has 39 national mooncake brands (品牌). Mooncakes there are large with thin wrappers (薄皮) and rich fillings. Each mooncake is as heavy as 3 kg. They have many kinds of tastes. Zhecheng hot peppersZhecheng county in Henan is famous for planting peppers. Each year, it sells more than 50,000 tons of hot peppers. Danish BlueIt is a kind of cheese from Denmark.

Recently, China has made a big step toward self-driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen. Why do we develop self-driving cars? Self-driving cars have many advantages (优点). They use computers with many cameras which can sense all the objects close to the car and give the computers another route (路线). Then the car can take people to the places where they want to go. For disabled or blind people, self-driving cars can also help them get around more easily. According to US Centers for Disease Control and Prevention, each year, more than 1.35 million people are killed on roads around the world. It’s reported that self-driving cars could reduce road accidents by 90 percent. The main cause of car accidents is human error (错误). By using computers, self-driving cars don’t make poor decisions or lose attention like humans do. But self-driving cars aren’t perfect. If something unexpected on the road happens, self-driving cars can’t react (反应) as fast as a human driver can. Also, during weather events like heavy snow, self-driving cars wouldn’t see the lines on the road easily. It might lead to an accident. The car’s computer system would be broken by someone, causing it to crash or change its direction.

AI is now a big part of our daily lives, leaving many people excited, while others feel worried. From education to delivery, almost no industry has been left unchanged by AI. Students can practice English by talking with AI, and creating a video can now be as simple as typing a few sentences. However, AI is surely a double-edged sword. While it brings great convenience and helps us work faster, it also has downsides. It could widen the gap between the rich and the poor, making powerful organizations stronger. Many repetitive jobs are now done by robots, which makes it harder for low-skilled workers who depend on those jobs to make a living. Even a powerful tech leader like Elon Musk wanted to pause more powerful AI, but he couldn’t stop its progress. So, will AI turn out to be humanity’s greatest invention, or will it become a future nightmare? Perhaps our grandchildren will be the ones who find out the answer. Beyond this, AI is also creating new tools in healthcare, transportation, and entertainment. It helps doctors analyze medical images and powers self-driving cars. Yet, it also raises serious questions about data privacy and the future of work. The future depends on the decisions we make today. 1．How can students use AI? A．To make videos quickly. B．To deliver packages. C．To change any industry. 2．Which of the following picture can best describe “a repetitive job”? A． B． C． 3．What did Elon Musk want to do about powerful AI? A．Stop its development for a while. B．Make it even more powerful. C．Let grandchildren answer questions about it. 4．What can we infer from the passage about the future of AI? A．Its development is certain to create more problems than it solves. B．Its advantages are widely recognized though it has risks. C．Its progress can be easily controlled by human decisions. 5．Why did the author write this passage? A．To introduce the latest AI products from a company. B．To encourage people to think carefully about AI’s future. C．To tell a story about Elon Musk and AI. 【答案】1．A 2．B 3．A 4．B 5．B 【知识点】科学技术、说明文 【导语】本文主要探讨了人工智能 (AI) 的发展现状及其带来的双重影响——既带来巨大便利与效率提升，也引发失业、贫富差距等社会问题，并指出其未来走向取决于人类当下的选择。 【详解】1．细节理解题。根据“Students can practice English by talking with AI, and creating a video can now be as simple as typing a few sentences.”可知，学生可以通过与AI对话练习英语，并且只需输入几句话就能轻松制作视频。因此，AI可以帮助学生快速制作视频。故选A。 2．推理判断题。根据“Many repetitive jobs are now done by robots, which makes it harder for low-skilled workers who depend on those jobs to make a living. ”可知，这里repetitive jobs指的是重复性工作 (单调、重复操作的任务) 。选项B中的人在流水线作业，反复做相同动作，最符合“重复性工作”的特征。故选B。 3．细节理解题。根据“Even a powerful tech leader like Elon Musk wanted to pause more powerful AI…”可知，马斯克希望暂停更强大AI的开发一段时间。故选A。 4．推理判断题。纵观全文，作者既列举了AI在教育、医疗等领域的积极应用，也指出了其可能加剧贫富分化、取代人力等风险，但并未全盘否定AI。根据最后一段“The future depends on the decisions we make today.”可推知，尽管AI有风险，但其优势已被广泛认识，未来走向取决于人类如何应对。故选B。 5．推理判断题。作者在文中客观分析了AI的利弊，并提出“AI会成为人类最伟大的发明还是未来的噩梦？也许我们的子孙后代会找到答案”，目的是引发读者对AI未来的深入思考，而非单纯介绍产品或讲述故事。故选B。 Passage6 （25-26九年级上·贵州贵阳·期中） Adult flamingos get their bright colors from the food they eat. But not all flamingos become the same color—pink. They can also become red, orange, or even white with pink, orange or red feathers mixed in. It all depends on the kinds of flamingos and the food in flamingos’ living places. All six kinds of flamingos live in different areas of the world. They usually stay in wetlands in different parts of the world. The food they eat has huge numbers of pigments (色素). When flamingos eat the food, the pigments are taken in and then left in their skin (皮肤), feathers and mouths. If flamingos aren’t able to eat enough food with these pigments, their colors may become less bright, and their feathers may also slowly lose colors because the strong sunlight in their living places shines on them. But some flamingos have the secret to making their feathers brightly colored. Some substances (油性物质) that make feathers bright are oily substances produced by themselves. The substance comes from the part near their tails. They reach back and apply the substance onto their skin and feathers. The more they apply, the brighter their skin and feathers will be! Being brightly colored is necessary because it helps flamingos look for mates. Also, different colors of flamingos look pretty cool. 1．What does the underlined word “They” in paragraph 1 refer to? A．The foods. B．The colors. C．The flamingos. 2．What may happen if flamingos don’t eat enough food with pigments? A．Their colors may become less bright. B．They may stop looking for mates. C．They may change their living places. 3．What’s the structure of the text?（P=paragraph） A． B． C． 4．What’s the text mainly about? A．Where Flamingos Live B．Why Flamingos Change Colors C．How Flamingos Find Their Food 【答案】1．C 2．A 3．B 4．B 【知识点】常见动物、说明文 【导语】本文是一篇说明文，主要讲述了火烈鸟羽毛色彩变化的相关知识，发现火烈鸟鲜亮色彩来源于食物中的色素，并探讨了色素、光照、自身油脂以及求偶需求对火烈鸟羽毛颜色的影响。 【详解】1．第一段指出：“But not all flamingos become the same color—pink. They can also become red, orange, or even white with pink, orange or red feathers mixed in.”，前一句主语是all flamingos，所以They指代flamingos（火烈鸟）。 2．第三段说明后果：“If flamingos aren’t able to eat enough food with these pigments, their colors may become less bright”，直接点明火烈鸟摄入含色素食物不足时，羽毛色彩会变得暗淡。 3．文章段落分层：P1总述火烈鸟色彩各不相同，P2、P3、P4分别介绍色素来源、缺色素褪色、自身增色的原理，P5总结鲜艳体色对火烈鸟的作用，因此文章为总—分—总结构。 4．全文围绕火烈鸟羽毛色彩展开，依次讲解色彩成因、褪色诱因、增色方法、鲜艳毛色的意义，核心是解释火烈鸟色彩发生改变的缘由，因此主旨为“Why Flamingos Change Colors”。 Passage7 （25-26九年级上·贵州铜仁·期中） We usually think that plants are quiet in the natural world. Grass doesn’t cry when you cut it. Flowers don’t scream when they’re picked. But our human view of the world misses quite a lot. Plants talk to each other all the time. Their language is chemical. Over the years, scientists have reported that different types of plants, from trees to tomatoes, release compounds (释放化合物) into the air to help neighboring plants. How plants receive and act on many of these signals (信号) is still mysterious. Recently, a team led by Junji Takabayashi of Japan’s Kyoto University has offered some explanations, as reported by Time magazine. The scientists looked at tomato plants bitten by insects. First, they grew plants in two plastic houses connected by a tube (管子). One plant was bitten by insects. The other was not. They found that when insects bite leaves, a plant doesn’t sit quietly. It releases a chemical called HexVic into the air. These chemicals carry a smell that neighboring plants can sense. People don’t notice it, though. This way, the neighboring plants understand the danger. They begin to make more HexVic to protect themselves. Later, scientists put insects on the other plants. The plants were able to kill about 50% of invaders (入侵者), much more than their sick neighbors. “It is surprising that plants don’t release a chemical until they get a warning message from their infested (受侵害的) neighbors,” scientists said. These findings may help farmers with pest control. 1．In Paragraph 1, the author (作者) leads in the topic by ________ . A．comparing things B．listing numbers C．giving examples 2．What is the correct order of the experiment process? a. About fifty percent of insects are dead. b. The neighboring plant smells the chemical. c. The plants are grown in two plastic houses. d. The plant bitten by insects releases a chemical. e. The plant starts to release more chemicals to protect itself. A．d-a-c-e-b B．c-d-b-e-a C．c-d-a-e-b 3．What is the correct structure of the passage? (P1=Paragraph 1) A． B． C． 4．What is the purpose of the passage? A．To show the relation between plants and insects. B．To show that plants have influences on each other. C．To explain how scientists do a biology experiment. 【答案】1．C 2．B 3．A 4．B 【知识点】说明文、植物 【导语】本文是一篇说明文，主要讲述了植物并非在自然界中保持“安静”，它们可以通过释放化学物质的方式彼此交流，当部分植物受到昆虫侵害时，会释放化学信号提醒邻近植物启动防御机制，同时介绍了相关科学实验及研究发现。 【详解】1．第一段指出“Grass doesn’t cry when you cut it. Flowers don’t scream when they’re picked.”，作者通过列举草被切割、花被采摘的具体例子，展现人们对植物“安静”的普遍认知，再引出植物会交流的事实，这种开篇方式属于举例子。 2．第二段对应“They grew plants in two plastic houses”（先将番茄植株种植在两个相连的塑料罩内）；第三段前半部分对应“It releases a chemical called HexVic into the air”（被虫子啃咬的植物释放化学物质）；第三段中段对应“These chemicals carry a smell that neighboring plants can sense”(邻近植物嗅到化学气味)；第三段后文对应“They begin to make more HexVic to protect themselves”(周边植物分泌更多化学物质自我防护)；第四段对应“The plants were able to kill about 50% of invaders”（约一半入侵害虫死亡）。完整顺序为c-d-b-e-a。 3．第一段总述核心观点“Plants talk to each other all the time. Their language is chemical.”；第二段至第四段按实验过程顺序展开，第五段总结意义，共同支撑第一段观点。为总—分—总结构。 4．第一段表示“Plants talk to each other all the time. Their language is chemical”，且文章通过实验说明，受昆虫侵害的植物会释放化学信号，让邻近植物提前启动防御机制，体现了植物之间会互相影响。 Passage8 （25-26九年级上·贵州毕节·期中） Pandas are one of the most popular animals in the world, and they are China’s national treasure. Most pandas live in Sichuan, Shaanxi, and Gansu provinces of China. Pandas mainly eat bamboo. An adult panda eats about 12 to 38 kilograms of bamboo every day. They spend 10 to 16 hours eating because bamboo doesn’t have much nutrition (营养). Pandas have a special “sixth finger”—it’s not a real finger, but a part of their wrist. It helps them hold bamboo easily. Pandas are usually quiet and slow. They like to sleep in trees or on the ground. Baby pandas are very small when they are born—only about 100 grams, which is as light as a small apple. They are pink and have no hair. After about 6 months, they start to eat bamboo and grow black-and-white fur. Now, pandas are in danger. The number of bamboo forests is getting smaller because of human activities, so pandas lose their homes. Also, pandas have few babies—usually one or two every two years. To protect pandas, China has built many nature reserves (保护区) for them. Now, the number of pandas is increasing slowly. 1．Where do most pandas live in China? A．In Hubei, Hunan, and Jiangxi. B．In Sichuan, Shaanxi, and Gansu. C．In Guangdong, Guangxi, and Fujian. 2．Why do pandas spend so much time eating? A．Because bamboo is delicious. B．Because they have nothing else to do. C．Because bamboo has little nutrition. 3．What do baby pandas look like when they are born? A．Black and white. B．Pink and hairless. C．Small and furry. 4．What has China done to protect pandas? A．Built many nature reserves. B．Moved pandas to other countries. C．Fed pandas with other food. 【答案】1．B 2．C 3．B 4．A 【知识点】说明文、濒危生物 【导语】本文是一篇说明文，主要介绍了熊猫这一中国国宝，包括它们的分布、饮食、身体特征、幼崽情况以及面临的生存危机和中国为保护它们所采取的措施。 【详解】1．细节理解题。根据第一段“Most pandas live in Sichuan, Shaanxi and Gansu provinces of China.”可知，大部分熊猫生活在四川、陕西和甘肃。故选B。 2．细节理解题。根据第二段“They spend 10 to 16 hours eating because bamboo doesn’t have much nutrition (营养).”可知，熊猫每天花很长时间进食是因为竹子营养少。故选C。 3．细节理解题。根据第三段“They are pink and have no hair.”可知，熊猫幼崽出生时是粉色且没有毛发的。故选B。 4．细节理解题。根据最后一段“To protect pandas, China has built many nature reserves (保护区) for them.”可知，中国为保护熊猫建立了许多自然保护区。故选A。 Passage9 （25-26九年级上·湖南湘西·期中） The Magic of Xiangxi’s Tea Deep in the mountains of Xiangxi, nature creates a perfect home for tea trees. This special environment gives the tea from this area a wonderful taste and smell, helping to create famous teas like Guzhang Maojian Tea, Berry Tea and Golden Tea. The tea culture here has a long history, with local people passing down traditional planting and picking methods from generation to generation. The high mountains here are often covered in thick clouds and mist. These clouds act like a soft blanket, protecting the young tea leaves from the strong sun. This allows the leaves to grow slowly and keep their fresh taste. What’s more, the air in Xiangxi is very clean and fresh. It is widely believed that the air quality here is exceptional, with very low levels of pollution. The forests are full of different plants, which make the soil rich and full of nutrients. When it rains, the water gets cleaned by the earth, reaching the tea trees in a pure state, This purity is another key to the tea’s quality. All these natural gifts work together like a team. They create a unique environment that cannot be easily found elsewhere. The tea trees grow happily in this balanced ecosystem, which teaches us an important lesson: when we protect nature and keep it in balance, it gives us its best gifts. This harmony between humans and nature is the true secret behind Xiangxi’s exceptional teas. 1．What is the main idea of the first paragraph? A．Xiangxi’s tea and its long history. B．The special taste of Xiangxi’s tea. C．The famous tea types in Xiangxi. 2．What does the underlined word “nutrients” in Paragraph 2 mean? A．Very small animals living in the soil. B．Water that comes from the mountains. C．Things that make plants grow strong and healthy. 3．Which of the following is NOT mentioned as a natural gift for Xiangxi’s tea? A．Clean air. B．Bright sunshine. C．Pure water. 4．According to the author, if your town wants to start a tea project (项目), what should you consider first? A．How to make the soil rich for the tea trees. B．How to use the local natural conditions in the best way. C．How to process tea while protecting the natural environment. 【答案】1．A 2．C 3．B 4．B 【知识点】说明文、种植与养殖 【导语】本文是一篇说明文，主要介绍了湘西独特的自然环境对孕育出品质优良茶叶的重要性，并强调了人与自然和谐共处是湘西茶叶卓越品质的真正秘诀。 1．根据第1段“Deep in the mountains of Xiangxi, nature creates a perfect home for tea trees...Berry Tea and Golden Tea”可知，前半段讲述了湘西独特的环境孕育了著名的茶叶。而后半段“The tea culture here has a long history, with local people passing down traditional planting and picking methods from generation to generation.”讲述了茶文化的悠久历史。因此，第一段既介绍了湘西的茶叶，也介绍了其悠久的历史。故选A。 2．根据第2段“The forests are full of different plants, which make the soil rich and full of nutrients.”以及常识可推测，森林中植物腐烂后会使土壤富含“养分”，这一推测与“make the soil rich”吻合。有了养分，植物也能够茁壮生长。因此，nutrients意为“使植物强壮健康生长的物质”。故选C。 3．根据第2段，文中提到了“clouds act like a soft blanket, protecting the young tea leaves from the strong sun”，云雾遮挡强光；“clean and fresh air”，洁净空气；“soil rich and full of nutrients”，土壤肥沃；“water gets cleaned by the earth”，有纯净水源。而文中指出白云可以保护茶树免受“强光”的伤害，由此可知，“strong sun”不是一种“自然馈赠”，这与“明亮的阳光”相对应，故选B。 4．根据最后一段，“All these natural gifts work together like a team. They create a unique environment that cannot be easily found elsewhere.”强调种植茶树要有独特且适合的环境。“The tea trees grow happily in this balanced ecosystem, which teaches us an important lesson: when we protect nature and keep it in balance, it gives us its best gifts. This harmony between humans and nature is the true secret behind Xiangxi’s exceptional teas.”强调，发展茶叶也要保护环境，实现发展经济与保护环境的平衡。由此可知，作者强调充分利用当地自然条件并保持人与自然和谐。因此，首先要考虑的是“如何最佳地利用当地的自然条件”。故选B。 Passage10 （25-26九年级上·海南省直辖县级单位·期中）Most countries have beautiful natural places.
