Most plants grow best in spring and summer because the weather is warm and there is a lot of rain. When autumn arrives, plants grow slower. Some may even die before winter comes. In autumn, their leaves turn yellow and fall off. Without leaves, plants will lose less water. It can help them live during winter. Each plant has its own habitat (生活环境). It is very important to them. They need a certain temperature , sunlight and humidity level (湿度). When their habitat is destroyed (毁坏), they may die. Nowadays, human activities cause a lot of pollution. This is bad for the growth of plants. For example, the greenhouse effect (温室效应) and acid (酸的) rain are destroying the forest. Lots of plants have died. It is telling us to fight against air pollution. However, many people don’t know that forests are the lungs of our Earth. We must protect the environment and that is protecting ourselves. 1．Why do plants grow well in spring and summer? A．Because there is less rain. B．Because the leaves fall off. C．Because the sun shines brightly. D．Because it is warm and rainy. 2．What helps plants live during winter? A．Yellow leaves. B．Falling leaves. C．Losing less water. D．Growing slower. 3．Which of the following is related to the habitat of plants? A．Temperature. B．Sunlight. C．Humidity level. D．All of the above. 4．What is Paragraph 2 mainly about? A．Plants can grow everywhere on Earth. B．The water is quite important to plants. C．The greenhouse effect is getting worse. D．The habitat is very important to plants. 5．What can we know about plants from the passage? A．All the plants will die in the cold winter. B．Air pollution is mainly caused by acid rain. C．The greenhouse effect is harmful to forests. D．Most people know the importance of forests. I love travelling around the world. I find there are different plants in different places. Coconut trees grow in hot places. They like a lot of rain and sunlight. They usually grow very tall. Lotuses grow in water. They often have beautiful flowers in summer. We can use their seeds to make Chinese medicine (药). We can also use their fruit to make delicious food. Pine trees grow in very cold places. They grow very tall and they are green all year round. Their leaves are long and thin. We use their wood to make and build things. 1．If someone wants to see the coconut trees, where should he go? A．To a cold place. B．To a dark place. C．To a hot place. D．To a dry place. 2．________ grow in water. A．Coconut trees B．Lotuses C．Pine trees D．All of the above 3．________ have long and thin leaves. A．Coconut trees B．Lotuses C．Pine trees D．None of the above 4．Which of the following is TRUE? A．Pine trees are green all year round. B．Lotuses often have beautiful flowers in spring. C．Pine trees grow best in hot places. D．Coconut trees don’t like a lot of rain and sunlight. 5．What’s the main idea of the passage? A．Different plants grow in different places. B．How to use plants in medicine. C．How to grow tall trees. D．Plants are important for building. Do you know a special kind of forest in China? We call it “the mangrove (红树林)”or “the red forest”. Are the mangroves red? No, mangroves don’t have red leaves. They are green. Mangroves grow mainly in the coastal areas under water. The place of mangrove planting in China is between 20°-30°N and 105°-120°E. Some parts of the trees are out of the water. They are home to reptiles like snakes. The other parts in the water make great homes for baby sea animals, like baby fish. Mangroves can grow as high as 10 meters. They keep the land away from strong winds and waves (海浪). Like other trees, mangroves take in CO2 to make O2. They help to make air clean on earth. But now many mangroves are in danger. We need to do more to protect them. 1．Which picture shows the Mangroves? A． B． C． D． 2．Which city in the map can grow Mangroves? A．A B．B C．C D．D 3．What does the underlined word (划线单词) “reptiles” in Paragraph 2 mean? A．Animals. B．Home. C．Trees. D．Waves. 4．How can mangroves be good for us? A．They can make the land stronger. B．They can keep the sea water clean. C．They can help the trees grow higher. D．They can stop waves reaching the land. 5．Why does the writer write the text? A．To tell a story of mangroves. B．To ask us to do something for mangroves. C．To answer why mangroves grow in water. D．To let us know where mangroves can grow. Bamboo is one of nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass. Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. Bamboo grows in many parts of the world. There are more than 1,500 kinds of bamboo. Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimetres wide, while (而) others may grow to more than 30 centimetres across. This plant also comes in different colours, from yellow to green to black. People use bamboo to make many things such as hats and kitchen tools (工具). People also use bamboo to build buildings because it is strong. Many Asian countries have used bamboo for thousands of years. They often use bamboo for buildings. In Africa, engineers are teaching farmers how to find water using bamboo. These African countries need cheap ways to find water. They have no money, and their fields often die from no rain and no water. Bamboo pipes (管子) and drills (钻) can help farmers bring water to their thirsty fields. 1．How is bamboo like grass? A．It grows quickly. B．It is wood. C．It is easy to cut. D．It is very thin. 2．The underlined sentence means “some other bamboo plants may grow to be very________”. A．short B．thick C．thin D．tall 3．In Asia, bamboo has been used for ________. A．a short time B．only a few years C．thousands of years D．about 100 years 4．Why do farmers in Africa use bamboo? A．Because it is cheap. B．Because it has different colours. C．Because it is strong. D．Because it is popular in Asia. 5．Bamboo pipes can ________. A．make money B．be trees C．grow quickly D．carry water In many people’s eyes, plants are quiet. They can’t talk. They can’t walk. And they can’t think like us. Or can they? A new TV show gives us a new look at plants. Shown on Jan.10 on Bilibili, it tells the secret lives of plants, and the wonderful and unbelievable ways that plants work. ________ In the rainforests, different kinds of plants race for sunlight. The forest floor is described as a “battlefield” (战场). Only two percent of the sunlight gets through it. Some plants spread (蔓延) their big leaves to reach light. But other plants may catch up with them and get a lift. Finally, they are both overtaken (超过) by a fast-growing tree. In the same way, some trees may give out something to protect themselves. Plants also help each other and even communicate. In deserts, if a tree finds water, it will share it with others. Studies also show that plants use fungus (真菌) in the soil as a way to “talk” to each other. It’s kind of like how Wi-Fi works. If a tomato plant gets ill, it can tell closer plants about it. The TV show not only makes us surprised at the plant world but also pushes us to understand that plants are important. “All life needs plants. We depend on them to eat and breathe (呼吸). It’s time to look after wild plants just as carefully as our houseplants.” said David, the director of the show. 1．A new TV show tells us that _______. A．plants are quiet and can’t talk B．plants aren’t able to walk C．plants can talk like humans D．plants work in unbelievable ways 2．Which of the following can be put in ________? A．Plants need water to live better. B．Plants can get sunlight from other plants. C．Plants grow slowly in rainforests D．Plants fight against each other to live. 3．What does the underlined phrase “catch up with them” in Paragraph 3 mean in Chinese? A．赶上它们 B．模仿它们 C．消灭它们 D．注意它们 4．From the passage, we know that ________. A．about 2% of plants can live in rainforests B．plants in deserts keep water all by themselves C．plants will know about the closer plants’ illnesses D．plants never share water with each other 5．In the last paragraph, David probably agrees that ________. A．plants are difficult to study B．plants are important in our lives C．wild plants are more important than houseplants D．houseplants also need our care 进阶拓展训练5篇 People need plants to live. Plants give us food, clothing, and oxygen (氧气). Trees, flowers and grass are all plants. Green plants need sun and water to grow. A plant usually has the following parts. Each part has a job to do. Some plants grow fruit. They usually have seeds in them. Apples, oranges and pears are all fruit. Many flowers are colourful. They help the plant to make seeds. Leaves grow out of the stem. How do leaves work? ▲ The stem grows up from the roots and helps the plant to stand. It gives food and water to other parts of the plant. The roots of a plant usually grow underground (地下的). They take in food and water for the plant. Seeds come in many sizes. When seeds are in the earth, they grow slowly and grow into new plants. 1．What can plants give us? ①food    ②clothing    ③water    ④oxygen A．①②③ B．①②④ C．①③④ D．②③④ 2．How many parts does a plant usually have? A．Three. B．Four. C．Five. D．Six. 3．What is one function (作用) of the stem? A．It helps the fruit to make seeds. B．It helps to make seeds for the plants. C．It takes in food and water from the earth. D．It gives food and water to other parts of the plant. 4．Which sentence can be put in the ▲ ? A．They help to make fruit. B．They use the sun to make food for the plant. C．Green leaves grow very quickly. D．Many animals eat green leaves. 5．In which part of the magazine can you read the text? A．Nature. B．Health. C．Education. D．Technology. Trees may seem quiet and still, but they have their own “senses” to survive in nature. Just like humans, they can feel, respond to and even “communicate” with the world around them. These special abilities help trees live for many years, even in difficult environments. Unlike humans, trees don’t have eyes, ears or hands, but their “senses” are enough to keep them safe and healthy. Trees have a strong sense of touch. When a caterpillar (毛毛虫) eats their leaves, they can feel the small bites and release a special smell to drive the caterpillar away. Sometimes, this smell can also attract other insects that eat caterpillars, helping trees get more protection. They can also sense changes in water. If there is little water in the soil, their roots will grow deeper to find more water, and their leaves will close a little to save water. Besides touch, trees can “hear” and “smell”. Some trees can sense the sound of wind and adjust their branches to avoid being broken. They can also smell harmful chemicals in the air and protect themselves by closing their leaf pores (气孔). When one tree is in danger, it sends out a chemical signal to warn other trees nearby, so they can get ready to protect themselves. In fact, trees are more amazing than we think. Their “senses” are not the same as ours, but they are very useful for their survival. By understanding tree senses, we can learn to protect them better and live in harmony with nature. Trees are important parts of our world, and their special abilities make our planet more beautiful. 1．What will trees do when a caterpillar eats their leaves? A．They will break their leaves. B．They will release a special smell. C．They will stop growing. D．They will change their color. 2．How do trees find more water when there is little water in the soil? A．Their leaves will become smaller. B．Their roots will grow deeper. C．Their branches will grow longer. D．They will release a signal. 3．What is the author’s attitude towards trees? A．Surprised and admiring. B．Bored and uninterested. C．Worried and sad. D．Respectful and critical. 4．Which structure does the passage follow? A．①—②③④ B．①—②—③—④ C．①—②③—④ D．①②—③④ 5．What’s the main idea of the passage? A．How trees grow fast. B．Trees can communicate with humans. C．How to protect trees. D．Trees have their own senses to survive. Hello, I am a rice seedling (水稻苗). In spring, people plant me and my friends in the soil. It rains a lot in spring so we have a lot of water to drink. We grow green and tall. Some people are working in the field and they are talking about us with smiling faces. A man says, “There is a lot of rain in spring so the rice grows so well. That’s great.” In summer, it seldom rains. Then we feel very thirsty. We can’t live if there is no water for us. Help! We want water! We are lucky that people try their best to find water for us. They bring us water from rivers, streams (溪流) and other places. They sometimes use a machine to get water for us. We drink, grow, and wait to ripen (成熟). “We can get a lot of rice this year,” many people say near us. 1．What does the underlined word “smiling” in Paragraph 2 mean in Chinese? A．自豪的 B．微笑的 C．难过的 D．漫不经心的 2．Why is the rice seedling thirsty in summer? A．Because the weather is so hot. B．Because it seldom rains. C．Because the rice grows fast. D．Because the rice is so tall. 3．What does the underlined word “it” in Paragraph3 refer to(指代)? A．The weather. B．The field. C．The soil. D．The water. 4．How do people sometimes get water for the rice seedling? A．By using a machine. B．By digging a well. C．By getting water from the sea. D．By waiting for rainwater. 5．Which of the following is True according to this text? A．People plant rice seedling in the soil in autumn. B．Rice can grow green and tall in spring because there is a lot of rain. C．People can’t get lots of rice this year because it seldom rains in summer. D．They always use a machine to get water for us. Young corn leaves can “smell” danger, but they lose this ability as they grow older, according to new research by Lei Wang and his team at the University of Bern. Plants can sense danger through smells, even though they don’t have noses. They can smell insect saliva (唾液). For example, when an insect eats corn leaves, the plant can smell the insect’s saliva and prepare to protect itself. Scientists have known this for a long time, but they didn’t know which parts of plants sense danger or how they do it. Wang’s team first studied adult corn leaves but found they didn’t produce many defense chemicals (防御化学物质) when in danger. So they had to turn over a new leaf. They studied young leaves instead, because they were better at “smelling” danger. In lab tests, young leaves produced more defense chemicals than adult leaves. However, adult leaves could still notice other dangers, like insects eating them. The researchers think young leaves are better at sensing danger because they are weaker and are at the top of the plant. From there, they can smell things from far away. This helps the plant get an early warning. Wang hopes this research will help develop smarter crops that can fight insects, cutting down the need for harmful pesticides (杀虫剂). By doing this research, he wants to help solve big farming problems. 1．How do plants notice danger, according to the text? A．By smelling insects’ saliva. B．By watching insects eat plants. C．By turning toward the danger. D．By killing insects with chemicals. 2．What does the underlined phrase “turn over a new leaf” in the passage mean? A．Improve a leaf’s health. B．Study a different leaf. C．Grow a fresh new leaf. D．Change the smell of a leaf. 3．Why are young leaves better at sensing danger? A．They get hurt more easily. B．They can kill insects quickly. C．They are stronger than adult leaves. D．They grow faster than adult leaves. 4．What probably will Lei Wang do in his future work? A．He will test leaf chemicals. B．He plans to make pesticides that work better. C．He plans to grow insect-resistant crops. D．He will research the problems of old leaves. 5．Which is the best title for the passage? A．The Secret Life of Plants B．Young Corn Leaves’ Special Ability C．A Study on Corn and Insects D．Farmers’ Fight Against Plant Insects Plants are very important to us. They help us in many ways. We humans can’t live without plants. Everyone needs air to live. Today, cars and factories make the air dirty. The dirty air is bad for our health. Plants help keep the air clean and fresh. Do you know where the oxygen (氧气) comes from? It comes from plants. Plants make the oxygen during the daytime, and they give it out for us to breathe. We eat plants to live. Plants are our daily food. The different parts of plants like roots, leaves (叶子) and seeds (种子) can be our food. The root is the part of the plant that grows in the soil. Carrots are roots of plants while cabbages are leaves of plants. They are delicious. We also eat the seeds of plants. For example, rice and sunflower seeds are seeds of plants. We can use plants to make many things. We use them to make tables and chairs, and we use cotton to make clothes. What’s more, some plants have medical (医疗的) use. We use them to make medicine. 根据材料内容选择最佳答案。 1．How does the writer make readers understand “Plants are our daily food”? A．By telling stories. B．By listing numbers. C．By giving examples.

When we cut them, they can make our eyes water. Many people enjoy eating them, but they are more than tasty; they are useful as well. Rich in vitamins, onions give great benefits to our bodies and help us stay healthy. ▲ A special plant called the corpse flower (巨魔芋) came out in Australia in January, 2025. You can see a flower like this only once every few years. It does not smell sweet but like bad meat because it wants to draw in small insects to help it bring the pollen (花粉) to other places. How Do Plants Work? It’ s a quarter past seven. Here’s Worker No.55 in his green clothes. He works in the leaf. He collects sunlight and CO₂ during the day. Workers from the root give him water. Then the plant will make sugar, which is useful. It also makes oxygen. Animals and humans need oxygen to breathe. 1．What will happen when we cut onions? A．Onions will give off good smell. B．We will get runny eyes. C．We will hurt our finger. D．We will become healthy. 2．Why are onions useful? A．Because they have different colors. B．Because they are delicious. C．Because they make people cry. D．Because they are good for our bodies. 3．What’s the best heading for the second piece of news? A．Why Is It Smelly? B．A Large Flower. C．How Do Insects Help? D．A Sweet Smell. 4．Which of the following tells how plants work? A．Water+Sunlight→Sugar+Oxygen+CO₂. B．Water+CO₂ +Sunlight→Sugar+Oxygen. C．Water+Sunlight+Sugar→Oxygen+CO₂. D．Sunlight+Sugar →Water+Oxygen+CO₂. 5．What do the three pieces of news have in common? A．They are all about the abilities of plants. B．They are all about exciting wildlife stories. C．They are all about the activities of plant workers. D．They are all about interesting geography knowledge. Do you like delicious blueberries? If so, when you eat next time, take a look at them. Are they really blue? Not really. Take off the skin. The inside is white. Rub (摩擦) the inside of a blueberry on a piece of white paper. It gets reddish-purple (红紫色). And if you rub the outside of a blueberry on it, it gets almost black. But the moment you pick one, it does look blue. Why? ①The first way is through “structural colour” (结构色). ②The blueberry makes “structural colour” in its own way. ③When the blueberry is full-grown, it is black. ④But a thin layer of wax on the outside of the blueberry gives it a blue look. The second is through plant pigments (色素). The pigments on the blueberry skin take in the green and yellow light and reflect (反射) the blue light. That’s why blueberries look blue in our eyes. In fact, there isn’t any “true blue” in the plants. We can also see the similar features on the green leaves. The blueberry’s special colour is cool. It shows nature’s magic. It holds many secrets for us to find! Now your bowl of blueberries suddenly looks a lot more interesting! 1．What color will a blueberry be after you rub the outside of it on the white paper? A．Blue. B．Black. C．White. D．Reddish-purple. 2．Where should the sentence “There are two ways to make colours.” be put in Paragraph 3? A．Before Sentence 1 B．Before Sentence 2 C．After Sentence 3 D．After Sentence 4 3．Which of the following probably shows why a blueberry looks blue in our eyes? A． B． C． D． 4．What does the writer infer about nature in the end? A．It shows its natural beauty. B．It has many kinds of fruits. C．It is too hard to understand. D．It has a lot for us to discover. 5．What does the writer want to explain to us in this passage? A．Why blueberries look blue. B．How blueberries change the skin. C．Where blueberries get their delicious taste. D．What makes blueberries cool in the plant world. We usually think that plants always stay quiet and never speak. Grass doesn’t cry when you cut it; flowers don’t scream (尖叫) when they’re picked (被摘). But this view of the world couldn’t be more wrong. Plants talk to each other all the time. Their language is one of chemicals (化学物质). Over the years, scientists have found that different types of plants, from trees to tomatoes, send compounds (化合物) into the air to help neighboring plants. But exactly how plants receive and act on many of these signals (信号) is still a mystery (secret). Scientists from Kyoto University in Japan looked at tomato plants that had been bitten by insects. To start out, they grew plants in two plastic bags connected by a tube (管子). One plant had been bitten (被咬) by insects. The other was not bitten (不被咬). They found that when insects bite plant leaves, the plants don’t sit quietly. They give off a chemical called “Hex Vic” into the air. Humans can’t notice it, but these chemicals carry an odor (气味) that neighboring plants can notice. This way, neighboring plants become aware of (意识到) the danger and begin to release more “Hex Vic” to protect themselves. The same scientists continued their experiment by placing insects on the plants that had not been bitten. The plants were able to kill nearly 50 percent of the invaders, much more than their neighbors. It was surprising that the plants that had not been bitten didn’t send out the chemical until they received a warning message from their neighbors, the scientists said. These findings could be used to help farmers with pest (害虫) control. 1．From the first two paragraphs, we know that ________. A．plants don’t talk to each other B．people see the world in a correct way C．plants talk to each other by sending out chemicals D．communication among plants is no longer a mystery 2．When bitten by insects, the tomato plant ________. A．died immediately afterwards B．sent out a chemical to warn others C．stayed quiet without doing anything D．wouldn’t be hurt again by the same insects 3．What does the underlined word “invaders” in Paragraph 5 refer to? A．Scientists. B．Hex Vic C．Tomato plant D．Insects. 4．Which of the following is TRUE according to the study? A．Tomato plants are easily bitten by insects. B．Hex Vic can help plants kill all the insects near them. C．The smell of Hex Vic is a kind of warning message. D．Plants won’t send out chemicals until they are attacked. 5．Where can we probably read this passage? A．In a newspaper. B．In an ad. C．In science fiction. D．In a science magazine. Why do the leaves on trees have different colors? What makes them change their colors? Leaves use sunlight, water and air to make food for the trees. This way of making food is called photosynthesis (光合作用). Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals. Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color. Many places get colder in autumn with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical (化学物质). The orange, yellow, and brown colors grow when that happens. Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves are icy while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights. Spring comes before long. Ice and snow disappear and the rains come. The sun shines, and tiny leaves grow from branches. Once again , the leaves use sunlight, water and air to make food. The cycle begins again. 1．What is photosynthesis according to the passage? A．It is a way of growing leaves. B．It is a way of changing colors. C．It is a way to make food for plants. D．It is a way for animals to eat plants. 2．What stops leaves from making the green chemical in autumn? A．Less air in autumn. B．Less sunlight in autumn. C．Less water in autumn. D．Less time in autumn. 3．What does the underlined word “They” in Paragraph 5 refer to? A．The trees. B．The leaves. C．The colors. D．The animals. 4．What would be the best structure of the passage? A．①②③④⑤\\⑥ B．①\\②③④⑤⑥ C．①\\②③④⑤\\⑥ D．①\\②③\\④\\⑤⑥ 5．What is the best title of the passage? A．The importance of the sunlight B．The trees in different seasons C．The colors of the tree leaves D．The changes of the four seasons Forests are made up of trees. Do you know the following types of forests on Earth? Temperate forest (温带森林) Temperate forests are found all over the world. These forests have four seasons. They change at different times of the year. Many kinds of trees grow in a temperate forest. Their leaves change colours with the seasons. Leaves fall off the trees when the weather gets cool. As the weather warms up, the trees sprout. Boreal forest (北方针叶林) Boreal forests are found in northern parts of the world, like North America, Asia, and Europe. Of the three types of forests, boreal forests have the shortest growing season, about 130 days. There days are cold, making it difficult for life. The largest boreal forest is in Russia, Europe. Animals there get used to the cold weather by growing thick fur (厚厚的皮毛). Tropical rainforest (热带雨林) You may guess that it rains a lot in a tropical rainforest. You are right! Tropical rainforests are hot and wet. These forests cover only a tenth of the Earth, yet they are home to more kinds of plants and animals than any other places. The biggest tropical rainforest is the Amazon. It is in South America and it’s home to 10% of the world’s plants and animals. Trees give us oxygen. They help clean the air. Cutting down too many trees will hurt the environment (环境). 1．How many kinds of forests are mentioned in the passage? A．4. B．3. C．2. D．1. 2．The underlined word “sprout” in the passage means “________”. A．grow new roots B．grow new leaves C．grow fruits D．grow new flowers 3．The biggest boreal forest is in ________.

A．a rainforest B．a temperate forest C．a boreal forest D．a tropical rainforest 5．This passage is mainly about ________. A．three kinds of forests B．animals in the forests C．weather of the forests D．plants in the forests 2 同步新教材，周周有练习，月月有重点！ 1 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $ 2025-2026学年一线教师制作新教材英语同步精品系列资料，名师遴选！ 2025-2026学年一线教师制作新教材英语同步精品系列资料，名师遴选！ 学校:___________姓名：___________班级：___________考号：___________ Unit 6 Trees 单元话题（人与植物）阅读理解进阶练15篇 说明：此专题分三个难度层次，基础入门训练<进阶拓展训练< 能力综合实践，老师根据学生实际情况进行针对性难度训练。 基础入门训练5篇 Plants grow everywhere. Most plants grow best in spring and summer because the weather is warm and there is a lot of rain. When autumn arrives, plants grow slower. Some may even die before winter comes. In autumn, their leaves turn yellow and fall off. Without leaves, plants will lose less water. It can help them live during winter. Each plant has its own habitat (生活环境). It is very important to them. They need a certain temperature , sunlight and humidity level (湿度). When their habitat is destroyed (毁坏), they may die. Nowadays, human activities cause a lot of pollution. This is bad for the growth of plants. For example, the greenhouse effect (温室效应) and acid (酸的) rain are destroying the forest. Lots of plants have died. It is telling us to fight against air pollution. However, many people don’t know that forests are the lungs of our Earth. We must protect the environment and that is protecting ourselves. 1．Why do plants grow well in spring and summer? A．Because there is less rain. B．Because the leaves fall off. C．Because the sun shines brightly. D．Because it is warm and rainy. 2．What helps plants live during winter? A．Yellow leaves. B．Falling leaves. C．Losing less water.

We call it “the mangrove (红树林)”or “the red forest”. Are the mangroves red? No, mangroves don’t have red leaves. They are green. Mangroves grow mainly in the coastal areas under water. The place of mangrove planting in China is between 20°-30°N and 105°-120°E. Some parts of the trees are out of the water. They are home to reptiles like snakes. The other parts in the water make great homes for baby sea animals, like baby fish. Mangroves can grow as high as 10 meters. They keep the land away from strong winds and waves (海浪). Like other trees, mangroves take in CO2 to make O2. They help to make air clean on earth. But now many mangroves are in danger. We need to do more to protect them. 1．Which picture shows the Mangroves? A． B． C． D． 2．Which city in the map can grow Mangroves?

Many people call this plant a tree, but it is a kind of grass. Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. Bamboo grows in many parts of the world. There are more than 1,500 kinds of bamboo. Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimetres wide, while (而) others may grow to more than 30 centimetres across. This plant also comes in different colours, from yellow to green to black. People use bamboo to make many things such as hats and kitchen tools (工具). People also use bamboo to build buildings because it is strong. Many Asian countries have used bamboo for thousands of years. They often use bamboo for buildings. In Africa, engineers are teaching farmers how to find water using bamboo. These African countries need cheap ways to find water. They have no money, and their fields often die from no rain and no water. Bamboo pipes (管子) and drills (钻) can help farmers bring water to their thirsty fields. 1．How is bamboo like grass? A．It grows quickly. B．It is wood. C．It is easy to cut.

They may only grow to be a few centimetres wide”，与之对比，“while others may grow to more than 30 centimetres across”，说明其他一些竹子会长得非常粗，thick表示“粗的”。 3．第五段提到“Many Asian countries have used bamboo for thousands of years”，说明在亚洲，竹子已经被使用了数千年。 4．最后一段提到“These African countries need cheap ways to find water. They have no money...Bamboo pipes (管子) and drills (钻) can help farmers bring water to their thirsty fields”，说明非洲农民使用竹子是因为它便宜。 5．最后一段提到“Bamboo pipes (管子) and drills (钻) can help farmers bring water to their thirsty fields”，说明竹子管道可以运水。 In many people’s eyes, plants are quiet. They can’t talk. They can’t walk. And they can’t think like us. Or can they? A new TV show gives us a new look at plants. Shown on Jan.10 on Bilibili, it tells the secret lives of plants, and the wonderful and unbelievable ways that plants work. ________ In the rainforests, different kinds of plants race for sunlight. The forest floor is described as a “battlefield” (战场). Only two percent of the sunlight gets through it. Some plants spread (蔓延) their big leaves to reach light. But other plants may catch up with them and get a lift. Finally, they are both overtaken (超过) by a fast-growing tree. In the same way, some trees may give out something to protect themselves. Plants also help each other and even communicate. In deserts, if a tree finds water, it will share it with others. Studies also show that plants use fungus (真菌) in the soil as a way to “talk” to each other. It’s kind of like how Wi-Fi works. If a tomato plant gets ill, it can tell closer plants about it. The TV show not only makes us surprised at the plant world but also pushes us to understand that plants are important. “All life needs plants. We depend on them to eat and breathe (呼吸). It’s time to look after wild plants just as carefully as our houseplants.” said David, the director of the show. 1．A new TV show tells us that _______. A．plants are quiet and can’t talk B．plants aren’t able to walk C．plants can talk like humans D．plants work in unbelievable ways 2．Which of the following can be put in ________?

A．about 2% of plants can live in rainforests B．plants in deserts keep water all by themselves C．plants will know about the closer plants’ illnesses D．plants never share water with each other 5．In the last paragraph, David probably agrees that ________. A．plants are difficult to study B．plants are important in our lives C．wild plants are more important than houseplants D．houseplants also need our care 【答案】1．D 2．D 3．A 4．C 5．B 【导语】本文是一篇说明文，主要介绍了一部新电视节目展现了植物不为人知的一面，揭示了植物之间奇妙的生存方式、相互帮助以及交流的能力，强调了植物对人类的重要性。 1．第二段提到节目“tells the secret lives of plants, and the wonderful and unbelievable ways that plants work”，说明这部新节目告诉我们植物以令人难以置信的方式运作。 2．第三段描述雨林中不同植物为争夺阳光展开竞争，一些植物蔓延大叶子获取光照，另一些植物则会相互对抗，由此可知该空应填“植物为了生存相互争斗”。 3．第三段前文提到一些植物蔓延大叶子去获取阳光，后文说另一些植物会“catch up with them”，结合语境可知此处指其他植物会“赶上”这些植物的生长速度，争夺阳光，故“catch up with them”意为“赶上它们”。 4．文中提到“If a tomato plant gets ill, it can tell closer plants about it”，即植物会将自身的病害情况告知邻近植物，由此可知植物会知道邻近植物的病害。 5．最后一段David提到“All life needs plants. We depend on them to eat and breathe. It's time to look after wild plants just as carefully as our houseplants”，表明植物对人类至关重要，他认为植物在我们的生活中很重要。 进阶拓展训练5篇 People need plants to live. Plants give us food, clothing, and oxygen (氧气). Trees, flowers and grass are all plants. Green plants need sun and water to grow. A plant usually has the following parts. Each part has a job to do.

How do leaves work?”结合常识可知，叶子的核心作用是通过光合作用，利用阳光为植物制造养分，对应选项B“它们利用阳光为植物制造食物”。 5．本文介绍的是植物的结构与功能，属于自然科普范畴，因此可推断最可能出现在杂志的“Nature(自然)”板块。 Trees may seem quiet and still, but they have their own “senses” to survive in nature. Just like humans, they can feel, respond to and even “communicate” with the world around them. These special abilities help trees live for many years, even in difficult environments. Unlike humans, trees don’t have eyes, ears or hands, but their “senses” are enough to keep them safe and healthy. Trees have a strong sense of touch. When a caterpillar (毛毛虫) eats their leaves, they can feel the small bites and release a special smell to drive the caterpillar away. Sometimes, this smell can also attract other insects that eat caterpillars, helping trees get more protection. They can also sense changes in water. If there is little water in the soil, their roots will grow deeper to find more water, and their leaves will close a little to save water. Besides touch, trees can “hear” and “smell”. Some trees can sense the sound of wind and adjust their branches to avoid being broken. They can also smell harmful chemicals in the air and protect themselves by closing their leaf pores (气孔). When one tree is in danger, it sends out a chemical signal to warn other trees nearby, so they can get ready to protect themselves. In fact, trees are more amazing than we think. Their “senses” are not the same as ours, but they are very useful for their survival. By understanding tree senses, we can learn to protect them better and live in harmony with nature. Trees are important parts of our world, and their special abilities make our planet more beautiful. 1．What will trees do when a caterpillar eats their leaves? A．They will break their leaves. B．They will release a special smell. C．They will stop growing. D．They will change their color. 2．How do trees find more water when there is little water in the soil? A．Their leaves will become smaller. B．Their roots will grow deeper. C．Their branches will grow longer. D．They will release a signal. 3．What is the author’s attitude towards trees? A．Surprised and admiring. B．Bored and uninterested. C．Worried and sad. D．Respectful and critical. 4．Which structure does the passage follow? A．①—②③④ B．①—②—③—④ C．①—②③—④ D．①②—③④ 5．What’s the main idea of the passage? A．How trees grow fast. B．Trees can communicate with humans. C．How to protect trees. D．Trees have their own senses to survive. 【答案】1．B 2．B 3．A 4．C 5．D 【导语】本文是一篇说明文，主要介绍了树木拥有自己的感官(触觉、听觉、嗅觉等)来感知环境、保护自己，从而在自然中生存。 1．第二段中提到“When a caterpillar eats their leaves, they can feel the small bites and release a special smell to drive the caterpillar away.”，由此可直接得出答案B，树木会释放一种特殊气味。 2．第二段中提到“If there is little water in the soil, their roots will grow deeper to find more water”，由此可直接得出答案B，树木的根会扎得更深。 3．第四段中提到“In fact, trees are more amazing than we think”和“Trees are important parts of our world, and their special abilities make our planet more beautiful”，由此可知作者对树木的态度是惊讶且赞赏的，对应选项A。 4．第一段总述树木有自己的感官，第二、三段分别介绍树木的不同感官，第四段总结树木的神奇与重要性，对应选项C。 5．第一段首句提到“Trees may seem quiet and still, but they have their own ‘senses’ to survive in nature”，结合全文可知，文章主要介绍了树木拥有自己的感官来生存，对应选项D。   Hello, I am a rice seedling (水稻苗). In spring, people plant me and my friends in the soil. It rains a lot in spring so we have a lot of water to drink. We grow green and tall. Some people are working in the field and they are talking about us with smiling faces. A man says, “There is a lot of rain in spring so the rice grows so well. That’s great.” In summer, it seldom rains. Then we feel very thirsty. We can’t live if there is no water for us. Help! We want water! We are lucky that people try their best to find water for us. They bring us water from rivers, streams (溪流) and other places. They sometimes use a machine to get water for us. We drink, grow, and wait to ripen (成熟). “We can get a lot of rice this year,” many people say near us. 1．What does the underlined word “smiling” in Paragraph 2 mean in Chinese? A．自豪的 B．微笑的 C．难过的 D．漫不经心的 2．Why is the rice seedling thirsty in summer? A．Because the weather is so hot. B．Because it seldom rains. C．Because the rice grows fast.

D．They always use a machine to get water for us. 【答案】1．B 2．B 3．A 4．A 5．B 【导语】本文以水稻苗的视角讲述了它从春天被种植、生长，到夏天缺水、被人们灌溉，等待成熟的过程。   1．第二段第三句“Some people are working in the field and they are talking about us with smiling faces.”可知，“smiling”在句中形容人们的表情，意为“微笑的”。 2．第三段“In summer, it seldom rains. Then we feel very thirsty.”可知，水稻苗在夏天感到口渴，是因为很少下雨。 3．第三段第一句“In summer, it seldom rains.”可知，这里的“it”指代天气，描述夏天少雨的天气状况。 4．第三段第八句“They sometimes use a machine to get water for us.”可知，人们有时会用机器为水稻苗取水。 5．第二段第一、二句“It rains a lot in spring so we have a lot of water to drink. We grow green and tall.”可知，B选项正确。 Young corn leaves can “smell” danger, but they lose this ability as they grow older, according to new research by Lei Wang and his team at the University of Bern. Plants can sense danger through smells, even though they don’t have noses. They can smell insect saliva (唾液). For example, when an insect eats corn leaves, the plant can smell the insect’s saliva and prepare to protect itself. Scientists have known this for a long time, but they didn’t know which parts of plants sense danger or how they do it. Wang’s team first studied adult corn leaves but found they didn’t produce many defense chemicals (防御化学物质) when in danger. So they had to turn over a new leaf. They studied young leaves instead, because they were better at “smelling” danger. In lab tests, young leaves produced more defense chemicals than adult leaves. However, adult leaves could still notice other dangers, like insects eating them. The researchers think young leaves are better at sensing danger because they are weaker and are at the top of the plant. From there, they can smell things from far away. This helps the plant get an early warning. Wang hopes this research will help develop smarter crops that can fight insects, cutting down the need for harmful pesticides (杀虫剂). By doing this research, he wants to help solve big farming problems. 1．How do plants notice danger, according to the text? A．By smelling insects’ saliva. B．By watching insects eat plants. C．By turning toward the danger. D．By killing insects with chemicals. 2．What does the underlined phrase “turn over a new leaf” in the passage mean? A．Improve a leaf’s health. B．Study a different leaf. C．Grow a fresh new leaf. D．Change the smell of a leaf. 3．Why are young leaves better at sensing danger? A．They get hurt more easily. B．They can kill insects quickly. C．They are stronger than adult leaves. D．They grow faster than adult leaves. 4．What probably will Lei Wang do in his future work? A．He will test leaf chemicals. B．He plans to make pesticides that work better. C．He plans to grow insect-resistant crops. D．He will research the problems of old leaves. 5．Which is the best title for the passage? A．The Secret Life of Plants B．Young Corn Leaves’ Special Ability C．A Study on Corn and Insects D．Farmers’ Fight Against Plant Insects 【答案】1．A 2．B 3．A 4．C 5．B 【导语】本文是一篇说明文，主要讲述了伯尔尼大学Lei Wang及其团队的新研究发现：玉米幼叶能“闻到”危险（通过感知昆虫唾液），但随着生长会失去这种能力，并探讨了幼叶更擅长感知危险的原因及该研究的意义。 1．第二段明确提到：“Plants can sense danger through smells... They can smell insect saliva”，说明植物通过闻到昆虫的唾液来察觉危险。 2．第三段前文提到研究成年玉米叶未发现其产生大量防御化学物质，后文指出“they studied young leaves instead”，由此可知“turn over a new leaf”在此处意为“改变研究方向、尝试新的研究对象，符合习语“重新开始、换一种方式”的引申用法。 3．第四段说明原因：“young leaves are better at sensing danger because they are weaker”，“weaker”对应“get hurt more easily”，即幼叶更容易受伤，因此更擅长感知危险。 4．最后一段提到：“Wang hopes this research will help develop smarter crops that can fight insects”，“crops that can fight insects”即抗虫作物，由此可推断雷王未来计划培育抗虫作物。 5．全文围绕雷王团队的研究展开，核心是“玉米幼叶能感知危险而成年叶不能”这一特殊能力，因此最佳标题为“Young Corn Leaves’ Special Ability”。 Plants are very important to us. They help us in many ways. We humans can’t live without plants. Everyone needs air to live. Today, cars and factories make the air dirty. The dirty air is bad for our health. Plants help keep the air clean and fresh. Do you know where the oxygen (氧气) comes from? It comes from plants. Plants make the oxygen during the daytime, and they give it out for us to breathe. We eat plants to live. Plants are our daily food. The different parts of plants like roots, leaves (叶子) and seeds (种子) can be our food. The root is the part of the plant that grows in the soil. Carrots are roots of plants while cabbages are leaves of plants. They are delicious. We also eat the seeds of plants. For example, rice and sunflower seeds are seeds of plants.

If so, when you eat next time, take a look at them. Are they really blue? Not really. Take off the skin. The inside is white. Rub (摩擦) the inside of a blueberry on a piece of white paper. It gets reddish-purple (红紫色). And if you rub the outside of a blueberry on it, it gets almost black. But the moment you pick one, it does look blue. Why? ①The first way is through “structural colour” (结构色). ②The blueberry makes “structural colour” in its own way. ③When the blueberry is full-grown, it is black. ④But a thin layer of wax on the outside of the blueberry gives it a blue look. The second is through plant pigments (色素). The pigments on the blueberry skin take in the green and yellow light and reflect (反射) the blue light. That’s why blueberries look blue in our eyes. In fact, there isn’t any “true blue” in the plants. We can also see the similar features on the green leaves. The blueberry’s special colour is cool. It shows nature’s magic. It holds many secrets for us to find! Now your bowl of blueberries suddenly looks a lot more interesting! 1．What color will a blueberry be after you rub the outside of it on the white paper? A．Blue. B．Black. C．White. D．Reddish-purple. 2．Where should the sentence “There are two ways to make colours.” be put in Paragraph 3? A．Before Sentence 1 B．Before Sentence 2 C．After Sentence 3 D．After Sentence 4 3．Which of the following probably shows why a blueberry looks blue in our eyes? A． B． C． D． 4．What does the writer infer about nature in the end? A．It shows its natural beauty. B．It has many kinds of fruits. C．It is too hard to understand. D．It has a lot for us to discover. 5．What does the writer want to explain to us in this passage? A．Why blueberries look blue. B．How blueberries change the skin. C．Where blueberries get their delicious taste. D．What makes blueberries cool in the plant world. 【答案】1．B 2．A 3．C 4．D 5．A 【导语】本文主要介绍了蓝莓为什么是蓝色的。 1．根据第二段“And if you rub the outside of a blueberry on it, it gets almost black.”可知，会是黑色。 2．根据第三段开头“The first way is through ‘structural colour’ (结构色).”和第四段开头“The second is through plant pigments (色素).”可知，下文具体介绍了两种具体的方式，所以这个句子应该放在①之前，起总起句作用。 3．根据第四段“The pigments on the blueberry skin take in the green and yellow light and reflect (反射) the blue light. That’s why blueberries look blue in our eyes.”可知，蓝莓表皮的色素吸收绿光和黄光，反射蓝光进入我们的眼睛，只有C图符合这个原理。 4．根据最后一段“The blueberry’s special colour is cool. It shows nature’s magic. It holds many secrets for us to find!”可知，作者认为大自然还有很多等待我们去发现。 5．全文围绕“为什么蓝莓看起来是蓝色”展开，介绍了两种让蓝莓呈现蓝色的原理，核心是解释蓝莓呈现蓝色的原因。 We usually think that plants always stay quiet and never speak. Grass doesn’t cry when you cut it; flowers don’t scream (尖叫) when they’re picked (被摘). But this view of the world couldn’t be more wrong. Plants talk to each other all the time. Their language is one of chemicals (化学物质). Over the years, scientists have found that different types of plants, from trees to tomatoes, send compounds (化合物) into the air to help neighboring plants. But exactly how plants receive and act on many of these signals (信号) is still a mystery (secret). Scientists from Kyoto University in Japan looked at tomato plants that had been bitten by insects. To start out, they grew plants in two plastic bags connected by a tube (管子). One plant had been bitten (被咬) by insects. The other was not bitten (不被咬). They found that when insects bite plant leaves, the plants don’t sit quietly. They give off a chemical called “Hex Vic” into the air. Humans can’t notice it, but these chemicals carry an odor (气味) that neighboring plants can notice. This way, neighboring plants become aware of (意识到) the danger and begin to release more “Hex Vic” to protect themselves. The same scientists continued their experiment by placing insects on the plants that had not been bitten. The plants were able to kill nearly 50 percent of the invaders, much more than their neighbors. It was surprising that the plants that had not been bitten didn’t send out the chemical until they received a warning message from their neighbors, the scientists said. These findings could be used to help farmers with pest (害虫) control. 1．From the first two paragraphs, we know that ________. A．plants don’t talk to each other B．people see the world in a correct way C．plants talk to each other by sending out chemicals D．communication among plants is no longer a mystery 2．When bitten by insects, the tomato plant ________. A．died immediately afterwards B．sent out a chemical to warn others C．stayed quiet without doing anything D．wouldn’t be hurt again by the same insects 3．What does the underlined word “invaders” in Paragraph 5 refer to? A．Scientists. B．Hex Vic C．Tomato plant D．Insects. 4．Which of the following is TRUE according to the study? A．Tomato plants are easily bitten by insects. B．Hex Vic can help plants kill all the insects near them. C．The smell of Hex Vic is a kind of warning message. D．Plants won’t send out chemicals until they are attacked. 5．Where can we probably read this passage? A．In a newspaper. B．In an ad. C．In science fiction. D．In a science magazine. 【答案】1．C 2．B 3．D 4．C 5．D 【导语】本文是一篇说明文。文章讲述了植物之间的谈话。 1．细节理解题。根据“Plants talk to each other all the time. Their language is one of chemicals ”可知，植物通过释放化学物质来相互交流。故选C。 2．细节理解题。根据“They found that when insects bite plant leaves, the plants don’t sit quietly. They give off a chemical called ‘Hex Vic’ into the air… This way, neighboring plants become aware of (意识到) the danger and begin to release more ‘Hex Vic’ to protect themselves.”可知，当被昆虫咬伤时，番茄植物会释放一种化学物质来警告其他植物。故选B。 3．词义猜测题。根据“The same scientists continued their experiment by placing insects on the plants that had not been bitten. The plants were able to kill nearly 50 percent of the invaders”可知，invaders指的是前文提到的“昆虫”。故选D。 4．推理判断题。根据“This way, neighboring plants become aware of (意识到) the danger and begin to release more ‘Hex Vic’ to protect themselves.”可知，Hex Vic的气味是一种警告信息。故选C。 5．推理判断题。这篇文章主要讲述了植物之间通过化学物质进行交流的科学发现，最有可能出现在科学杂志上。故选D。 Why do the leaves on trees have different colors? What makes them change their colors? Leaves use sunlight, water and air to make food for the trees. This way of making food is called photosynthesis (光合作用). Photosynthesis is important to animals as well as plants. Some animals eat plants. Other animals eat these animals. Summer is playtime. For the leaves of many trees, however, it’s work, work, work! The sun is shining. The leaves are making food for the trees. The trees keep more than enough food deep inside. Leaves are green in summer because they are making food. Leaves also have orange, yellow, or brown colors inside them. During summer, those colors are covered by the green color. Many places get colder in autumn with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical (化学物质). The orange, yellow, and brown colors grow when that happens. Once it gets cold enough and ice appears at night, the trees drop their leaves. They do this to keep themselves safe. If the leaves are icy while still on the trees, the trees can be hurt. Trees that drop their leaves are bare (光秃秃) in winter. They use the food they save in summer to get through the cold days and nights. Spring comes before long. Ice and snow disappear and the rains come. The sun shines, and tiny leaves grow from branches. Once again , the leaves use sunlight, water and air to make food. The cycle begins again. 1．What is photosynthesis according to the passage? A．It is a way of growing leaves. B．It is a way of changing colors. C．It is a way to make food for plants. D．It is a way for animals to eat plants. 2．What stops leaves from making the green chemical in autumn? A．Less air in autumn. B．Less sunlight in autumn. C．Less water in autumn. D．Less time in autumn. 3．What does the underlined word “They” in Paragraph 5 refer to? A．The trees. B．The leaves. C．The colors. D．The animals. 4．What would be the best structure of the passage? A．①②③④⑤\\⑥ B．①\\②③④⑤⑥ C．①\\②③④⑤\\⑥ D．①\\②③\\④\\⑤⑥ 5．What is the best title of the passage? A．The importance of the sunlight B．The trees in different seasons C．The colors of the tree leaves D．The changes of the four seasons 【答案】1．C 2．B 3．A 4．C 5．C 【导语】本文主要探讨树叶颜色变化的原因，介绍了光合作用对树叶的作用，以及不同季节树叶颜色变化和树木落叶等现象背后的原理。 1．细节理解题。根据“Leaves use sunlight, water and air to make food for the trees. This way of making food is called photosynthesis (光合作用).”可知，光合作用是树叶为树木制造食物的一种方式。故选C。 2．细节理解题。根据“Many places get colder in autumn with shorter days and longer nights. Trees get less sunlight, so photosynthesis slows down. Over time, leaves stop making the green chemical (化学物质).”可知，秋天树木接受的阳光变少，光合作用减缓，树叶停止制造绿色化学物质，所以是秋天阳光变少导致的。故选B。 3．词句猜测题。根据“Once it gets cold enough and ice appears at night, the trees drop their leaves.”和“They do this to keep themselves safe.”可知，这里They指代前文的the trees，表示树木落叶是为了保护自己。故选A。 4．篇章结构题。通读原文可知，文章第一段提出树叶颜色不同及变化原因的问题，属于总起；第二至五段分别从光合作用、不同季节树叶的变化等方面进行阐述；第六段写春天到来树叶又开始新的循环，是总结。所以结构是总分总。故选C。 5．主旨大意题。通读原文可知，文章围绕树叶颜色展开，讲述了树叶颜色不同以及在不同季节变化的原因等内容，C选项“树叶的颜色”符合文章主旨。故选C。 Forests are made up of trees. Do you know the following types of forests on Earth? Temperate forest (温带森林) Temperate forests are found all over the world. These forests have four seasons. They change at different times of the year. Many kinds of trees grow in a temperate forest. Their leaves change colours with the seasons. Leaves fall off the trees when the weather gets cool. As the weather warms up, the trees sprout. Boreal forest (北方针叶林) Boreal forests are found in northern parts of the world, like North America, Asia, and Europe. Of the three types of forests, boreal forests have the shortest growing season, about 130 days. There days are cold, making it difficult for life. The largest boreal forest is in Russia, Europe. Animals there get used to the cold weather by growing thick fur (厚厚的皮毛). Tropical rainforest (热带雨林) You may guess that it rains a lot in a tropical rainforest. You are right! Tropical rainforests are hot and wet. These forests cover only a tenth of the Earth, yet they are home to more kinds of plants and animals than any other places. The biggest tropical rainforest is the Amazon. It is in South America and it’s home to 10% of the world’s plants and animals. Trees give us oxygen. They help clean the air. Cutting down too many trees will hurt the environment (环境). 1．How many kinds of forests are mentioned in the passage? A．4. B．3. C．2. D．1. 2．The underlined word “sprout” in the passage means “________”. A．grow new roots B．grow new leaves C．grow fruits D．grow new flowers 3．The biggest boreal forest is in ________. A．Africa B．South America C．Europe D．North America 4．The best kind of forest for plants and animals to live in is ________. A．a rainforest B．a temperate forest C．a boreal forest D．a tropical rainforest 5．This passage is mainly about ________. A．three kinds of forests B．animals in the forests C．weather of the forests D．plants in the forests 【答案】1．B 2．B 3．C 4．D 5．A 【导语】本文主要介绍了三种类型的森林。 1．细节理解题。根据三个小标题“Temperate forest”“Boreal forest”以及“Tropical rainforest”可知，文中一共介绍了三种森林。故选B。 2．词句猜测题。根据第二段中“Leaves fall off the trees when the weather gets cool. As the weather warms up, the trees sprout.”可知，天气变凉时，树叶从树上落下来，天气变暖时，树木会长出新叶子。故画线单词意为“长出新叶子”。故选B。 3．细节理解题。根据第三段中“The largest boreal forest is in Russia, Europe.”可知，最大的北方针叶林在欧洲的俄罗斯。故选C。 4． 细节理解题。根据第四段中“You may guess that it rains a lot in a tropical rainforest. You are right! Tropical rainforests are hot and wet. These forests cover only a tenth of the Earth, yet they are home to more kinds of plants and animals than any other places.”可知，对植物和动物来说最好的森林是热带雨林。故选D。 5．主旨大意题。通读全文可知，本文主要介绍了三种类型的森林。故选A。 2 同步新教材，周周有练习，月月有重点！ 1 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $
