Some areas on Earth’s land are 1 by water or have water just below the soil. This may be all year round or for just part of the year. These 2 are called wetlands. Wetlands come in many forms. These 3 rivers, lakes, swamps (沼泽) and so on. Most large wetland areas have more than one of these forms. Wetlands are 4 to lots of different animals, such as frogs and snakes. Flying birds, like 5 geese and ducks, rest in wetlands during their long trips. And two-thirds of all the fish we eat 6 at least part of their lives in wetlands. Wetlands cover only 6 percent of the Earth’s surface, 7 they play a big role in nature. They can clean the 8 water from cities and farms.

Blood Falls in Antarctica is a waterfall which pours blood-red water into a river. The sight is a perfect background for a horror (恐怖) film: full of mysteries (神秘) and of course bloody. Its special colour was long believed to be caused by red algae (红藻). Until 2017, the true cause of the so-called blood was proved to be oxidized iron (被氧化的铁) in saltwater. ________ Amazing yet a dangerous sight, frozen bubbles can be seen in winter at Abraham Lake in Canada. When there is too much methane (甲烷) gas underwater and it is frozen, it will finally form this special sight-frozen bubbles. Such plenty of methane has a high risk. So even a lit match can cause an explosion (爆炸). Mirror(镜子)of the Sky! During the new moon and full moon times, tourists can see a clear reflection (反射) of the sky in the waters of Sasaran Beach in Malaysia. The smooth sand and lowest water level (水位) create such an unbelievable sight. Also known as the “Mirror of the Sky”, this water beach is an amazing place to take pictures. 11．In which part of the newspaper can we read the news? A．PEOPLE. B．BIOLOGY. C．TRADITION. D．NATURE. 12．The best title for the second news would be “________” A．How Beautiful a Lake! B．Too Dangerous to Visit! C．Special Frozen Bubbles! D．Here Come Explosions! 13．What do the three pieces of news above have in common (共同)? A．They can be seen only by the sea. B．They introduce places fit for visiting. C．They are all very dangerous. D．They show the causes of the special sights. B Water is important for all living things on Earth. The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the earth again. It is a cycle that happens the whole year and is most active from March to May in China. In this article, we will learn about the water cycle and discuss its importance for Earth. The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow. The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water. Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty. 14．Which season has the most active water cycle in China? A．Spring. B．Summer. C．Autumn. D．Winter. 15．Which is the right order of the water cycle according to the passage? a. Water returns to the ground.            b. Rain or snow falls down. c. Water vapour rises up.                    d. Clouds are formed in the sky. A．c-b-d-a B．c-d-b-a C．d-c-b-a D．d-b-c-a 16．Why is the water cycle important? A．Because it brings people warm weather. B．Because it cleans the air and the ground. C．Because it makes the climate healthy. D．Because it shows the beauty of nature. 17．Which shows the structure of the passage? A． B． C． D． C As we all know, climate change has greatly influenced the birds’ living environment. Take Poyang Lake as an example. As an important habitat for the seriously endangered birds, Poyang Lake has experienced unusual rises and falls in recent years. “In some years, the lake experiences floods, while in others it experiences a shortage of rain. Both of these situations lead to less food in the birds’ habitat,” a scientist told China Daily. To solve such habitat problems, China has named about 1,000 places these years as important living and winter places in wetlands. To protect China’s wetlands, a law was also made in 2022 to control human activities. According to the law, people can’t overuse the wetlands. What's more, they can’t pour (倒) waste water into the wetlands. Since these methods have worked well, more birds have been seen living in the nation’s wetlands. In February, Hunan Province reported that more than 70 kinds of water birds had spent the past winter at Dongting Lake, and that the number of one endangered kind of birds had increased from 300 in the 1980s to more than 5,000 at present. All of these cases show a better future. 18．How does the writer begin the text? A．By asking and answering questions. B．By listing numbers and giving ideas. C．By comparing two different ideas. D．By listing a fact and giving an example. 19．What does the underlined word “shortage” mean? A．缺少 B．充足 C．跌落 D．获得 20．What does the writer think of the future of wetlands protection? A．Interested. B．Worried. C．Surprised. D．Hopeful. 21．We can read this passage in the ________ part of a magazine. A．Sports B．Nature C．Travel D．Geography D Sunshine, beaches and coconuts (椰子) —these are why people usually go to Hainan. But more than a good place for travelers and foodies, it’s also a wonderland of plants and animals. Hainan Tropical Rainforest National Park in the south-central part of Hainan Island, has the most and well-kept tropical rain forests in China. President Xi Jinping visited it in April, 2023. The national park covers 4,269 square kilometers, or one-seventh of the island. More than 95 percent of the park is virgin (原始的) forest and is home to 3,653 species (种类) of vascular plants and 540 species of terrestrial vertebrates. The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地) . They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection. Not just a sweet home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather. With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon rainforest in Brazil. That’s why people call the park a treasure for both China and the world. 22．Paragraph 2 is mainly about ________. A．an introduction to the park B．the views of the park C．the news of the park's opening D．details of rare plants and animals 23．What do we know about the Hainan gibbon? A．It is a monkey without a tail. B．Its voice sounds like a crying baby. C．It lives on plants and birds. D．It is a species only found in Hainan. 24．From the story, we can infer that a cycas hainanensis plant ________. A．never blossoms and has fruit B．can only live for 10 years in Hainan C．lives better in warm and wet weather D．first blossoms when it is 10 years old 25．Which of the following may be the writer’s opinion? A．Human activities will surely hurt the rainforest. B．We must start to do something for rare species. C．China has done a great job in protecting the rainforest. D．We should compare our rainforest with the Amazon rainforest. 三、信息还原。(本大题共5小题，每小题1分，共5分) 阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有一项为多余选项。 We throw away rubbish almost every day. Do you know where it goes? 26 There are five large rubbish patches (垃圾带) in the sea. The largest one is the Great Pacific Rubbish Patch. Scientists are saying that the patch is getting even bigger than before. The patch is in the Pacific Ocean between California and Hawaii. It is quite large. According to Live Science, it has an area of 1.6 million square kilometers. 27 Most of the rubbish is plastic (塑料), including bottles, bags and fishing nets. According to Fox News, there are about 79,000 tons (吨) of plastic in the patch. That’s about 250 pieces of plastic for every person on Earth. 28 This plastic can harm sea animals and pollute the water. 29 But the most important thing is to stop rubbish from going into the sea in the first place. Where is sea rubbish from? People throw their rubbish directly (直接地) into the ocean. Wind can also blow rubbish into the ocean. 30 Then, the rivers carry the rubbish to the ocean. A．Rain can wash the rubbish into rivers. B．Is one of those pieces from you? C．Every person should throw rubbish into rubbish bins. D．Most of it goes into the sea. E．We should take action to protect sea animals and the sea. F．That is about 100 times bigger than Beijing. G．Scientists are trying different ways to clean up rubbish in the sea. 四、词汇运用。(本大题共13小题，每小题1分，共13分) 第一节 请认真阅读下面短文，并根据各题所给的汉语注释或首字母提示，在答题卡标有题号的横线上，写出空缺处各单词的正确形式。每空限填一词。 31．The c________ here is neither too dry nor too wet, making it suitable for the growth of this plant. 32．The doctor says drinking too much cola is h________ to your health. 33．When you have difficulty s________ the problem, you can ask me for help, and I will give you a helping hand. 34．—Do you know what ________ (生态系统) are on earth? —Yes, oceans, wetlands and so on. 35．24 solar terms show the wisdom and k________ of ancient Chinese people. 36．He took out the picture of the balloons and stuck it on the ________ /'kʌvə(r)/. 37．The truck is carrying t________ of steel to the new factory. 38．The sunlight we are all used to i________ seven different colours. 第二节 请认真阅读下面短文，从方框中选择适当的单词或短语，在答题卡标有题号的横线上，填入其正确形式。每个单词或短语仅用一次。 trap   have    sponge    non-living   take in 1．The table is a object made of wood. 2．—Shall we go to the nature park this weekend? —Good idea.

It reminds us to save water, because water is the most important natural resource on the Earth. Water covers more than 70% of the Earth’s surface, but most of that is sea water. People can’t use it directly in daily life. Fresh water takes up only 2.5% of the total water. People in many places are facing serious water problems. One of them is water pollution. Many kinds of waste from cars, factories, farms and homes make rivers, lakes, and oceans dirty. Polluted water is very bad for people’s health. And dirty water is also bad for sea life. Now, 34% of fishes are dying out. The biggest source (来源) of pollution comes from cars and factories. In the beginning, waste from cars and factories pollutes the air. Then, when it rains, the rainwater comes down and makes our drinking water dirty. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save water. Here is some advice. ●Turn off the tap while you are brushing your teeth. ●Leaky (漏水的) taps waste a lot of water. Fix them right away! ●You can easily cut your shower time short, and you’ll be still clean. ●Only wash clothes when you have a lot to wash. If your washing machine isn’t full, you’re wasting water. 54．What does “it” refer to in Paragraph One? 55．According to the advice mentioned in the passage, how can you save water when you take a shower? 56．What other ideas do you have to save water? Please give two ideas. 七、书面表达。(共25分) 保护环境是每个人的责任和义务，我们在生活中的点滴改变就能使环境有所改变。假如21世纪英文报纸正在征文，请以“What Can We Do for the Environment”为题，写一篇短文： 提示： (1) The importance of protecting the environment; (2) What can we do?

Scientists are saying that the patch is getting even bigger than before. The patch is in the Pacific Ocean between California and Hawaii. It is quite large. According to Live Science, it has an area of 1.6 million square kilometers. 27 Most of the rubbish is plastic (塑料), including bottles, bags and fishing nets. According to Fox News, there are about 79,000 tons (吨) of plastic in the patch. That’s about 250 pieces of plastic for every person on Earth. 28 This plastic can harm sea animals and pollute the water. 29 But the most important thing is to stop rubbish from going into the sea in the first place. Where is sea rubbish from? People throw their rubbish directly (直接地) into the ocean. Wind can also blow rubbish into the ocean. 30 Then, the rivers carry the rubbish to the ocean. A．Rain can wash the rubbish into rivers. B．Is one of those pieces from you? C．Every person should throw rubbish into rubbish bins. D．Most of it goes into the sea.

It reminds us to save water, because water is the most important natural resource on the Earth. Water covers more than 70% of the Earth’s surface, but most of that is sea water. People can’t use it directly in daily life. Fresh water takes up only 2.5% of the total water. People in many places are facing serious water problems. One of them is water pollution. Many kinds of waste from cars, factories, farms and homes make rivers, lakes, and oceans dirty. Polluted water is very bad for people’s health. And dirty water is also bad for sea life. Now, 34% of fishes are dying out. The biggest source (来源) of pollution comes from cars and factories. In the beginning, waste from cars and factories pollutes the air. Then, when it rains, the rainwater comes down and makes our drinking water dirty. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to save water. Here is some advice. ●Turn off the tap while you are brushing your teeth. ●Leaky (漏水的) taps waste a lot of water. Fix them right away! ●You can easily cut your shower time short, and you’ll be still clean. ●Only wash clothes when you have a lot to wash. If your washing machine isn’t full, you’re wasting water. 54．What does “it” refer to in Paragraph One? 55．According to the advice mentioned in the passage, how can you save water when you take a shower? 56．What other ideas do you have to save water? Please give two ideas. 七、书面表达。(共25分) 保护环境是每个人的责任和义务，我们在生活中的点滴改变就能使环境有所改变。假如21世纪英文报纸正在征文，请以“What Can We Do for the Environment”为题，写一篇短文： 提示： (1) The importance of protecting the environment; (2) What can we do?

Blood Falls in Antarctica is a waterfall which pours blood-red water into a river. The sight is a perfect background for a horror (恐怖) film: full of mysteries (神秘) and of course bloody. Its special colour was long believed to be caused by red algae (红藻). Until 2017, the true cause of the so-called blood was proved to be oxidized iron (被氧化的铁) in saltwater. ________ Amazing yet a dangerous sight, frozen bubbles can be seen in winter at Abraham Lake in Canada. When there is too much methane (甲烷) gas underwater and it is frozen, it will finally form this special sight-frozen bubbles. Such plenty of methane has a high risk. So even a lit match can cause an explosion (爆炸). Mirror(镜子)of the Sky! During the new moon and full moon times, tourists can see a clear reflection (反射) of the sky in the waters of Sasaran Beach in Malaysia. The smooth sand and lowest water level (水位) create such an unbelievable sight.

The water cycle (循环) is a natural process that takes water from the ground and the sky and brings it back to the earth again. It is a cycle that happens the whole year and is most active from March to May in China. In this article, we will learn about the water cycle and discuss its importance for Earth. The water cycle always begins with water vapour (蒸汽). When it’s hot outside, you can see clouds forming in the sky. These clouds are made of water vapour that comes from the ground, plants and rivers. As water vapour rises into the sky, it cools down and becomes clouds. After that, clouds travel through the sky and fall back to Earth as rain or snow. Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow. The water cycle is important in protecting our Earth’s climate (气候). It provides us with water to drink and keeps our climate healthy. On top of that, it takes water from rivers and oceans and brings it to the areas that don’t have enough water. Without the cycle, we would face many problems. When there is too much water in one place, it becomes a flood. When water is badly in need, it becomes a drought. Besides, water vapour can take heat from the sun and keep our Earth cool. The water cycle is a natural process that keeps our Earth alive. It’s important for plants and animals to drink water and for our rivers to stay flowing with water. Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty. 14．Which season has the most active water cycle in China? A．Spring. B．Summer. C．Autumn. D．Winter. 15．Which is the right order of the water cycle according to the passage? a. Water returns to the ground.            b. Rain or snow falls down. c. Water vapour rises up.                    d. Clouds are formed in the sky. A．c-b-d-a B．c-d-b-a C．d-c-b-a D．d-b-c-a 16．Why is the water cycle important? A．Because it brings people warm weather. B．Because it cleans the air and the ground. C．Because it makes the climate healthy. D．Because it shows the beauty of nature. 17．Which shows the structure of the passage? A． B． C． D． 【答案】14．A 15．B 16．C 17．A 【导语】本文是一篇说明文。主要介绍了地球上的水循环。了解水循环可以帮助我们享受自然之美，了解我们的地球是如何运作的，并找到更好的方法来保护我们的地球。 【详解】14．细节理解题。根据“It is a cycle that happens the whole year and is most active from March to May in China.”可知，水循环在三月到五月最为活跃，即春季。故选A。 15．推理判断题。根据“The water cycle always begins with water vapour.”可知，水循环从水蒸气开始；根据“As water vapour rises into the sky, it cools down and becomes clouds.”可知，然后是水蒸气遇冷变成云；根据“After that, clouds travel through the sky and fall back to Earth as rain or snow.”可知，接下来云向地面降水；根据“Then, water runs through rivers and oceans and finally returns to the earth again in different forms like rainwater or snow.”可知，最后水以雨水或雪的形式回到地面。故选B。 16．推理判断题。根据“The water cycle is important in protecting our Earth’s climate. It provides us with water to drink and keeps our climate healthy.”可知，水循环可以保护我们的气候健康。故选C。 17．篇章结构题。根据“Water is important for all living things on Earth.”可知，文章首段通过说水很重要引出水循环这个话题；根据“The water cycle always begins with water vapour.”和“The water cycle is important in protecting our Earth’s climate.”可知，二、三段讲述了水循环的过程及其重要性；根据“Understanding the water cycle can help us enjoy the beauty of nature, know how our Earth works and find better ways to protect our Earth and that is our duty.”可知，最后一段总结全文，告诉我们要保护地球。故选A。 C As we all know, climate change has greatly influenced the birds’ living environment. Take Poyang Lake as an example. As an important habitat for the seriously endangered birds, Poyang Lake has experienced unusual rises and falls in recent years. “In some years, the lake experiences floods, while in others it experiences a shortage of rain. Both of these situations lead to less food in the birds’ habitat,” a scientist told China Daily. To solve such habitat problems, China has named about 1,000 places these years as important living and winter places in wetlands. To protect China’s wetlands, a law was also made in 2022 to control human activities. According to the law, people can’t overuse the wetlands. What's more, they can’t pour (倒) waste water into the wetlands. Since these methods have worked well, more birds have been seen living in the nation’s wetlands. In February, Hunan Province reported that more than 70 kinds of water birds had spent the past winter at Dongting Lake, and that the number of one endangered kind of birds had increased from 300 in the 1980s to more than 5,000 at present. All of these cases show a better future. 18．How does the writer begin the text? A．By asking and answering questions. B．By listing numbers and giving ideas. C．By comparing two different ideas. D．By listing a fact and giving an example. 19．What does the underlined word “shortage” mean? A．缺少 B．充足 C．跌落 D．获得 20．What does the writer think of the future of wetlands protection? A．Interested. B．Worried. C．Surprised. D．Hopeful. 21．We can read this passage in the ________ part of a magazine. A．Sports B．Nature C．Travel D．Geography 【答案】18．D 19．A 20．D 21．B 【导语】本文是一篇说明文，主要讲述了气候变化对鸟类生存环境的影响，以及中国为保护湿地和鸟类所采取的措施及其成效。 【详解】18．推理判断题。根据文章第一段“As we all know, climate change has greatly influenced the birds’ living environment. Take Poyang Lake as an example.”可知，作者通过列举事实（气候变化影响鸟类生存）并给出具体例子（鄱阳湖）开篇。故选D。 19．词句猜测题。根据文章第二段“In some years, the lake experiences floods, while in others it experiences a shortage of rain.”可知，“shortage”与“floods”形成对比，意为“不足、缺少”。故选A。 20．观点态度题。根据文章最后一段“All of these cases show a better future.”可知，作者对湿地保护的未来持乐观态度。故选D。 21．推理判断题。全文围绕湿地保护、鸟类生存环境及气候变化展开，属于自然生态话题。因此最可能出现在杂志的“自然”板块。故选B。 D Sunshine, beaches and coconuts (椰子) —these are why people usually go to Hainan. But more than a good place for travelers and foodies, it’s also a wonderland of plants and animals. Hainan Tropical Rainforest National Park in the south-central part of Hainan Island, has the most and well-kept tropical rain forests in China. President Xi Jinping visited it in April, 2023. The national park covers 4,269 square kilometers, or one-seventh of the island. More than 95 percent of the park is virgin (原始的) forest and is home to 3,653 species (种类) of vascular plants and 540 species of terrestrial vertebrates. The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon. It’s an uncommon species. They look like monkeys, but have no tails. They live in the trees their whole life. Every morning, they whistle loudly to mark their territory (领地) . They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has become larger from fewer than 10 in the 1980s to 36 in 2022. This shows China’s achievements in environmental protection. Not just a sweet home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather. With so many plants and animals, the biodiversity index (指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon rainforest in Brazil. That’s why people call the park a treasure for both China and the world. 22．Paragraph 2 is mainly about ________. A．an introduction to the park B．the views of the park C．the news of the park's opening D．details of rare plants and animals 23．What do we know about the Hainan gibbon? A．It is a monkey without a tail. B．Its voice sounds like a crying baby. C．It lives on plants and birds. D．It is a species only found in Hainan. 24．From the story, we can infer that a cycas hainanensis plant ________. A．never blossoms and has fruit B．can only live for 10 years in Hainan C．lives better in warm and wet weather D．first blossoms when it is 10 years old 25．Which of the following may be the writer’s opinion? A．Human activities will surely hurt the rainforest. B．We must start to do something for rare species. C．China has done a great job in protecting the rainforest. D．We should compare our rainforest with the Amazon rainforest. 【答案】22．A 23．D 24．C 25．C 【导语】本文是一篇说明文，主要介绍了海南热带雨林国家公园及其动植物的多样性。 【详解】22．主旨大意题。根据第二段可知，国家公园占地4269平方公里，占全岛面积的七分之一。公园95%以上是原始森林，是3653种维管植物和540种陆生脊椎动物的家园。这是对国家公园的介绍。故选A。 23．细节理解题。根据第三段“The park is the only home of the world’s most endangered primate (灵长类动物)—the Hainan gibbon.”可知，该公园是世界上最濒危的灵长类动物海南长臂猿的唯一栖息地。故选D。 24．推理判断题。根据第四段“But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and have fruit almost every year, thanks to the warm and wet weather.”可知，但在海南，由于天气温暖潮湿，10年以上的海南苏铁几乎每年都会开花结果，说明苏铁在温暖潮湿的气候中生长得更好。故选C。 25．推理判断题。通过全文和“It is comparable to the Amazon rainforest in Brazil.”可知，主要介绍了海南热带雨林国家公园，其动植物的多样性可与巴西的亚马逊雨林相媲美。由此可知在保护热带雨林方面，中国做得很好。故选C。 三、信息还原。(本大题共5小题，每小题1分，共5分) 阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有一项为多余选项。 We throw away rubbish almost every day. Do you know where it goes? 26 There are five large rubbish patches (垃圾带) in the sea. The largest one is the Great Pacific Rubbish Patch. Scientists are saying that the patch is getting even bigger than before. The patch is in the Pacific Ocean between California and Hawaii. It is quite large.
