It is the 13th of China’s 24 solar terms. This day usually comes on August 7 or 8. In 2025, it starts on August 7. Though autumn begins, hot weather often stays. People call this the “Autumn Tiger” (秋老虎). Changes in Nature Mornings and evenings get cooler after Liqiu. You may see yellow leaves on some trees and hear fewer cicadas (蝉) chirping. Farmers are busy because it’s harvest time for corn and cotton. In southern China, people prepare for typhoons (台风) and heavy rain. Special Customs Chinese people do these things to celebrate Liqiu: - Tie Qiu Biao (Eating meat): In the north, people eat roast duck or meat to become stronger after the hot summer. - Ken Qiu (Biting Autumn): Families in the south eat watermelons together. They believe it helps drive away the summer heat. - Sun-drying Crops: In mountain villages like Huangling, villagers dry red peppers and golden corn in the sun. It creates colourful “autumn pictures”. Staying Healthy Doctors advise eating pears, honey and lilies (百合). These foods keep our lungs healthy in the dry autumn air. Also, wearing a light jacket in the morning can prevent colds. A Season of Hope An old Chinese saying tells us: “A cool morning at Liqiu brings a good year.” Though days are still warm, Liqiu brings hope for harvests and cool winds.

Today, we pay more attention to the ocean itself in the ocean exploration. In recent years, new technology has made it easier to dive (潜水) into the deep sea. Better submarines (潜艇), robots and cameras now allow scientists to explore areas people couldn’t reach before. China’s Mengxiang deep-ocean drilling vessel (大洋钻探船) can now be added to the list. Believe it or not, we know more about space than we do about the deep sea. Since 1969, only three have dived to the Mariana Trench’s deepest point. Even more shocking? Although the ocean covers about 71% of Earth’s surface, 95% of it is unexplored. Why does so much of the ocean remain unknown? Part of the reason is that it’s difficult to explore. Sure, it’s hard to get a spaceship into space. But remember that in space, you can see things. The deep sea, however, is hopelessly dark. Getting a light down there that can shine far enough is no easy task. That being said, ocean exploration is worth the risk and cost. The ocean is connected to all of us and plays a role in everything from the air we breathe, the food we eat and the transportation of the goods we buy to weather and longer-term climate trends (趋势). The deep ocean also holds huge amounts of oil, gas, metals and so on. 1. Why didn’t scientists reach the deep sea in the past? A．They didn’t think it was worth the risk. B．They didn’t have high-level technology. C．They thought there was no need to do it. D．They wanted the knowledge from shallower waters. 2. What can we learn from Paragraph 2? A．Mengxiang deep-ocean drilling vessel is popular with tourists. B．Mengxiang deep-ocean drilling vessel is mainly used for trade. C．China has made great progress in ocean exploration technology. D．China is the first country to explore shallower and deeper waters. 3. Why does the writer mention space in the passage? A．To prove the interest of ocean exploration. B．To show the necessity of space exploration. C．To show the difficulty of ocean exploration. D．To prove the importance of space exploration. 4. What does the underlined word “task” refer to? A．Inventing a new light. B．Seeing the things in space. C．Getting a spaceship into space. D．Sending a bright enough light down. 5. What can we learn from the passage? A．Deep ocean exploration is important and necessary. B．The ocean influences the long-term climate trends most. C．We have explored most of the resources in the deep waters. D．The ocean coverage is large and we have explored most of it. 【答案】1. B 2. C 3. C 4. D 5. A 【导语】本文是一篇说明文，主要讲述了海洋探索的相关内容。 1. 细节理解题。根据“In recent years, new technology has made it easier to dive (潜水) into the deep sea. Better submarines (潜艇), robots and cameras now allow scientists to explore areas people couldn’t reach before.”可知，近年来新技术使深海潜水更容易，以前科学家无法到达深海是因为没有高水平的技术，故选B。 2. 细节理解题。根据“China’s Mengxiang deep-ocean drilling vessel (大洋钻探船) can now be added to the list.”并结合前文提到新技术助力海洋探索可知，中国的大洋钻探船是新技术的体现，说明中国在海洋探索技术方面取得了很大进步，故选C。 3. 推理判断题。根据“Believe it or not, we know more about space than we do about the deep sea. Since 1969, only three have dived to the Mariana Trench’s deepest point.”可知，作者提到太空是为了对比，显示出相比太空，人类对深海了解更少，突出海洋探索的难度，故选C。 4. 词句猜测题。根据“The deep sea, however, is hopelessly dark. Getting a light down there that can shine far enough is no easy task.”可知，然而，深海一片漆黑。要让光线穿透到足够远的地方绝非易事。“task”指的是把足够亮的光送到深海，故选D。 5. 细节理解题。根据“That being said, ocean exploration is worth the risk and cost.”可知，海洋探索值得冒险和成本，且海洋影响人类生活的方方面面（如空气、食物、气候）且蕴藏资源。选项A“深海探索重要且必要”符合。故选A。 Passage 5 The Magic of the Coral Reef Coral reefs are one of the most amazing natural wonders on Earth. They are often called “the rainforests of the sea” because they are home to thousands of species of fish, plants and other creatures. Coral reefs cover less than 0.1% of the ocean floor, but they support more than 25% of all marine species. Coral reefs are not just rocks. They are made up of tiny living creatures called coral polyps. These polyps live in groups and secrete a hard substance that forms the structure of the reef. Coral reefs grow very slowly—only about 1 to 2 centimeters per year. Some coral reefs have been around for millions of years. However, coral reefs are in great danger now. Climate change is causing the ocean temperature to rise, which makes the coral turn white and die. Pollution from factories and farms is also harming the reefs. Plastic waste in the ocean can get stuck on the reefs and kill the polyps. In addition, overfishing is destroying the balance of the marine ecosystem. But there is hope. Many organizations and individuals are working hard to protect coral reefs. Scientists are researching ways to help coral reefs adapt to climate change. Volunteers are cleaning up plastic waste from the ocean. Governments are making laws to stop overfishing and pollution. We can also do our part to protect coral reefs. For example, we can reduce our carbon footprint by saving energy and using public transport. We can also avoid buying products that harm coral reefs, such as certain sunscreens. Every small action can help save these beautiful natural wonders. 1. Why are coral reefs called “the rainforests of the sea”? A．They are as big as rainforests. B．They grow in the same area as rainforests. C．They support a large number of species. D．They are made up of tiny plants. 2. What does the underlined word “secrete” mean in Chinese? A．吸收 B．分泌 C．消耗 D．储存 3. Which of the following is NOT a threat to coral reefs? A．Rising ocean temperatures. B．Plastic pollution. C．Overfishing. D．Marine protected areas. 4. What can we infer from the passage? A．Coral reefs grow very quickly. B．Only scientists can protect coral reefs. C．If we take action, coral reefs can be saved. D．Coral reefs are not important for the marine ecosystem. 5. What is the main idea of the passage? A．Coral reefs are home to many marine species. B．Coral reefs are in danger and need protection. C．How coral reefs are formed. D．Why coral reefs are important. 【答案】1. C 2. B 3. D 4. C 5. B 【导语】本文是一篇说明文，介绍了珊瑚礁的特点、面临的威胁以及人类保护珊瑚礁的努力。 1. 细节理解题。根据第一段“They are often called ‘the rainforests of the sea’ because they are home to thousands of species…”可知，珊瑚礁被称为“海洋中的雨林”，是因为它们支持大量物种生存。故选C。 2. 词句猜测题。根据第二段“These polyps live in groups and secrete a hard substance that forms the structure of the reef.”可知，这里指珊瑚虫“分泌”一种坚硬物质形成珊瑚礁结构，因此secrete意为“分泌”。故选B。 3. 细节理解题。根据第三段提到的威胁包括气候变暖、污染、塑料垃圾和过度捕捞，而marine protected areas（海洋保护区）是保护措施，不是威胁。故选D。 4. 推理判断题。根据第四段和第五段介绍人们采取各种措施保护珊瑚礁，以及“Every small action can help save these beautiful natural wonders.”可推知，只要采取行动，珊瑚礁仍有希望被保护。故选C。 5. 主旨大意题。文章先介绍珊瑚礁，再重点说明其面临危险以及保护方法，因此主旨是珊瑚礁处于危险之中，需要保护。故选B。 三、任务型阅读 Passage 6 阅读下面短文，根据短文内容完成句子。 Plants do not just make our homes look beautiful. Some of them also play a surprising part in our lives. We all know that plants are important in Chinese medicine. One of the most popular plants in Chinese medicine is ginseng. Doctors believe that ginseng is good for people’s health. They often use ginseng as medicine to protect people from some illnesses. Also, Chinese people use ginseng to cook different dishes. In India, people are no stranger to neem because they use it a lot. Neem is useful in solving some common health problems like sore throats and skin disorders (喉咙痛和皮肤病). In ancient India, people used neem branches (树枝)for cleaning their teeth. Even today, some supermarkets still sell toothpaste (牙膏) made from it. Another very popular plant is aloe vera.

However, people cut down too many trees to build farms and roads. When this happens, many animals lose their homes and some even disappear forever. Rainforests also help to clean the air. The trees take in carbon dioxide and give us oxygen. If we lose too many rainforests, the Earth will become hotter and the air will become dirtier. We must take action to protect them. There are many ways we can help. We can use less paper, recycle more, and buy products that come from safe, sustainable sources. We can also learn more about the rainforest and tell others why it is important. Every small action helps the planet. 1. The rainforest is one of the most places on our planet. 2.

In 2025, it starts on August 7. Though autumn begins, hot weather often stays. People call this the “Autumn Tiger” (秋老虎). Changes in Nature Mornings and evenings get cooler after Liqiu. You may see yellow leaves on some trees and hear fewer cicadas (蝉) chirping. Farmers are busy because it’s harvest time for corn and cotton. In southern China, people prepare for typhoons (台风) and heavy rain. Special Customs Chinese people do these things to celebrate Liqiu: - Tie Qiu Biao (Eating meat): In the north, people eat roast duck or meat to become stronger after the hot summer. - Ken Qiu (Biting Autumn): Families in the south eat watermelons together. They believe it helps drive away the summer heat. - Sun-drying Crops: In mountain villages like Huangling, villagers dry red peppers and golden corn in the sun. It creates colourful “autumn pictures”. Staying Healthy Doctors advise eating pears, honey and lilies (百合). These foods keep our lungs healthy in the dry autumn air. Also, wearing a light jacket in the morning can prevent colds. A Season of Hope An old Chinese saying tells us: “A cool morning at Liqiu brings a good year.” Though days are still warm, Liqiu brings hope for harvests and cool winds. It reminds us that every ending is a quiet new beginning. 1. What does “Liqiu” mean in Chinese? A．The End of Summer. B．The Start of Autumn. C．The Middle of Autumn. D．The Beginning of Winter. 2. When will Liqiu start in 2025? A．On August 6. B．On August 7. C．On August 8. D．On August 9. 3. Why do people call the lingering hot weather after Liqiu “Autumn Tiger”?

What change can people notice in nature after Liqiu? A．Mornings and evenings become hotter. B．More cicadas start chirping loudly. C．Farmers begin planting corn and cotton. D．Some trees get yellow leaves. 5. Which custom is popular in southern China during Liqiu? A．Eating roast duck to get stronger. B．Sharing watermelons to drive away summer heat. C．Drying crops in mountain villages. D．Wearing heavy coats in the morning. Passage 4 Historically, people explored the ocean to find new ways to travel around the world or to start new trade routes. Today, we pay more attention to the ocean itself in the ocean exploration. In recent years, new technology has made it easier to dive (潜水) into the deep sea. Better submarines (潜艇), robots and cameras now allow scientists to explore areas people couldn’t reach before. China’s Mengxiang deep-ocean drilling vessel (大洋钻探船) can now be added to the list. Believe it or not, we know more about space than we do about the deep sea. Since 1969, only three have dived to the Mariana Trench’s deepest point. Even more shocking? Although the ocean covers about 71% of Earth’s surface, 95% of it is unexplored. Why does so much of the ocean remain unknown? Part of the reason is that it’s difficult to explore. Sure, it’s hard to get a spaceship into space. But remember that in space, you can see things. The deep sea, however, is hopelessly dark. Getting a light down there that can shine far enough is no easy task. That being said, ocean exploration is worth the risk and cost. The ocean is connected to all of us and plays a role in everything from the air we breathe, the food we eat and the transportation of the goods we buy to weather and longer-term climate trends (趋势). The deep ocean also holds huge amounts of oil, gas, metals and so on. 1. Why didn’t scientists reach the deep sea in the past? A．They didn’t think it was worth the risk. B．They didn’t have high-level technology. C．They thought there was no need to do it. D．They wanted the knowledge from shallower waters. 2. What can we learn from Paragraph 2? A．Mengxiang deep-ocean drilling vessel is popular with tourists. B．Mengxiang deep-ocean drilling vessel is mainly used for trade. C．China has made great progress in ocean exploration technology. D．China is the first country to explore shallower and deeper waters. 3. Why does the writer mention space in the passage? A．To prove the interest of ocean exploration. B．To show the necessity of space exploration. C．To show the difficulty of ocean exploration. D．To prove the importance of space exploration. 4. What does the underlined word “task” refer to? A．Inventing a new light. B．Seeing the things in space. C．Getting a spaceship into space. D．Sending a bright enough light down. 5. What can we learn from the passage? A．Deep ocean exploration is important and necessary. B．The ocean influences the long-term climate trends most. C．We have explored most of the resources in the deep waters. D．The ocean coverage is large and we have explored most of it. Passage 5 The Magic of the Coral Reef Coral reefs are one of the most amazing natural wonders on Earth. They are often called “the rainforests of the sea” because they are home to thousands of species of fish, plants and other creatures. Coral reefs cover less than 0.1% of the ocean floor, but they support more than 25% of all marine species. Coral reefs are not just rocks. They are made up of tiny living creatures called coral polyps. These polyps live in groups and secrete a hard substance that forms the structure of the reef. Coral reefs grow very slowly—only about 1 to 2 centimeters per year. Some coral reefs have been around for millions of years. However, coral reefs are in great danger now. Climate change is causing the ocean temperature to rise, which makes the coral turn white and die. Pollution from factories and farms is also harming the reefs. Plastic waste in the ocean can get stuck on the reefs and kill the polyps. In addition, overfishing is destroying the balance of the marine ecosystem. But there is hope. Many organizations and individuals are working hard to protect coral reefs. Scientists are researching ways to help coral reefs adapt to climate change. Volunteers are cleaning up plastic waste from the ocean. Governments are making laws to stop overfishing and pollution. We can also do our part to protect coral reefs. For example, we can reduce our carbon footprint by saving energy and using public transport. We can also avoid buying products that harm coral reefs, such as certain sunscreens. Every small action can help save these beautiful natural wonders. 1. Why are coral reefs called “the rainforests of the sea”? A．They are as big as rainforests. B．They grow in the same area as rainforests. C．They support a large number of species. D．They are made up of tiny plants. 2. What does the underlined word “secrete” mean in Chinese? A．吸收 B．分泌 C．消耗 D．储存 3. Which of the following is NOT a threat to coral reefs? A．Rising ocean temperatures. B．Plastic pollution. C．Overfishing. D．Marine protected areas. 4. What can we infer from the passage? A．Coral reefs grow very quickly. B．Only scientists can protect coral reefs. C．If we take action, coral reefs can be saved. D．Coral reefs are not important for the marine ecosystem. 5. What is the main idea of the passage? A．Coral reefs are home to many marine species. B．Coral reefs are in danger and need protection. C．How coral reefs are formed. D．Why coral reefs are important. 三、任务型阅读 Passage 6 阅读下面短文，根据短文内容完成句子。 Plants do not just make our homes look beautiful. Some of them also play a surprising part in our lives. We all know that plants are important in Chinese medicine. One of the most popular plants in Chinese medicine is ginseng. Doctors believe that ginseng is good for people’s health. They often use ginseng as medicine to protect people from some illnesses. Also, Chinese people use ginseng to cook different dishes. In India, people are no stranger to neem because they use it a lot. Neem is useful in solving some common health problems like sore throats and skin disorders (喉咙痛和皮肤病). In ancient India, people used neem branches (树枝)for cleaning their teeth. Even today, some supermarkets still sell toothpaste (牙膏) made from it. Another very popular plant is aloe vera. I guess this name makes us think of some cosmetics (化妆品). People often use aloe Vera to make cosmetics and medicines. It can help solve some skin problems like hair loss and sunburn (脱发和晒伤). It’s useful and easy to grow, so people often bring this plant into their homes. 1. Plants can make our homes . 2. In China, doctors believe that the plant ginseng is good for . 3. Neem is helpful in solving like sore throats and skin disorders. 4. People in ancient India used neem branches to . 5. People often bring aloe Vera into their homes because it’s . Passage 7 Save the Rainforest! The rainforest is one of the most important places on Earth. It is home to thousands of plants and animals. Many of the foods we eat, like bananas, chocolate, and coffee, come from the rainforest. However, people cut down too many trees to build farms and roads. When this happens, many animals lose their homes and some even disappear forever. Rainforests also help to clean the air. The trees take in carbon dioxide and give us oxygen. If we lose too many rainforests, the Earth will become hotter and the air will become dirtier. We must take action to protect them. There are many ways we can help. We can use less paper, recycle more, and buy products that come from safe, sustainable sources. We can also learn more about the rainforest and tell others why it is important. Every small action helps the planet. 1. The rainforest is one of the most places on our planet. 2. It is home to many different and . 3. People often down trees to make space for farms and roads. 4. The rainforest trees take in carbon dioxide and give us to breathe. 5. If we lose too many rainforests, the air will become and the Earth will become hotter. 6. To protect rainforests, people should use less and more. 四、短文填空 Passage 8 根据短文内容及首字母提示，填写所缺单词，使短文意思完整，每空限填一词。 The natural world is filled with living things. Living things start out weak and small, and s 1 grow strong and big. You are a living thing. Flowers, grass and trees are living things, too. Bees, ants, dogs and cats—these are all living things. All living things need food and water to s 2 . From these basic needs, living things get the strength to grow. Think about y 3 . If you are hungry, you need to eat. You eat fruit, vegetables, meat and fish. They can p 4 you with energy. You drink water every time you feel thirsty. Now think about a tree. W 5 a tree is hungry, it gets food from the soil (土壤). Trees drink water, too. We are different in some ways, but all living things are connected. We are all on the same planet, and we depend on each other. If we pollute the rivers and oceans, fish may get s 6 or even die. Some birds l 7 on fish. If the birds eat these fish, they may die. This can have t 8 effects on ecosystems. Nature is a b 9 between all the living things on the planet. If one species (物种) dies off, then another species may die off, followed by another, and another... We must a 10 now. We should respect the earth and protect all the living things on it. Passage 9 阅读下面短文，根据首字母提示补全单词，使短文完整、通顺。每空限填一词。 Major Snow, the 21st solar term of the year, marks the start of midwinter. During Major Snow, the t 1 falls greatly, and there may be more snow. Farmers welcome the snow, because when fields are c 2 with snow, the snow acts like a blanket (毛毯) that traps warmth in the soil, so h 3 is less likely to be lost. In this way, crops are protected from cold frost. Even i 4   the snow melts, it can also provide enough water for the g 5 of some winter crops in spring. The s 6 season is also perfect for sports like skiing or skating. There are many such places for natural snow and ice in the n 7 part of China. For example, Heilongjiang and Jilin provinces often have heavy snow in November, leaving rivers and lakes f 8 , which makes ice sports common. Though we have much interest in playing with snow, we should pay attention to respiratory (呼吸的) i 9 . When it’s Major Snow, it is much colder and drier, so people should drink more water. We can also drink hot soup with ginger (生姜) and Chinese dates (枣) to fight a 10   the cold. Passage 10 首字母填空 What will our world be like if there are no insects? It might sound nice in the b 1 . There would be no bugs or flies in your room. But in fact, this could cause really s 2 problems. The bad news is that the n 3 of insects is getting smaller and smaller these years.
