Their colourful wings make gardens and parks come alive. But did you know that butterflies go through an amazing change during their lives? A butterfly's life begins as a tiny egg. When the egg hatches, a caterpillar comes out. The caterpillar is very hungry and spends most of its time eating leaves. It grows very fast and sheds its skin several times. After a few weeks, the caterpillar forms a chrysalis around its body. Inside the chrysalis, something magical happens. The caterpillar's body completely changes. After about one to two weeks, a beautiful butterfly comes out of the chrysalis. This process is called metamorphosis. The newly emerged butterfly waits for its wings to dry and then flies off to find flowers. Butterflies feed on nectar from flowers. While they feed, they also carry pollen from one flower to another, helping plants grow fruits and seeds. Sadly, many kinds of butterflies are disappearing. The use of pesticides and the loss of wild flowers have reduced their numbers. We can help butterflies by planting more flowers in our gardens and avoiding the use of harmful chemicals. ( ) 16. What does a caterpillar do most of the time? A. Sleeping. B. Eating leaves. C. Flying around. D. Drinking water. ( ) 17. What is the hard case that a caterpillar forms around its body called? A. A cocoon. B. A chrysalis. C. A shell. D. A nest. ( ) 18. How do butterflies help plants? A. By eating harmful insects. B. By carrying pollen from flower to flower. C. By digging the soil around the plants. D. By giving water to the plants. ( ) 19. What can people do to help butterflies? A. Catch them and keep them in cages. B. Use more pesticides in gardens. C. Plant more flowers and avoid harmful chemicals. D. Cut down more trees in forests. 第二篇 阅读下面短文,根据短文内容选择最佳答案。(共4小题;每小题1.5分,满分6分) When you walk in a forest, you may think the trees are standing alone quietly. But scientists have discovered that trees are actually talking to each other. They communicate through an underground network that connects their roots. This network is made of tiny fungi that grow among the roots. The fungi and the tree roots work together. The fungi help the trees absorb water and nutrients from the soil. In return, the trees give the fungi sugars they produce from sunlight. Scientists call this the "wood wide web". Through this network, trees can send signals to each other. If insects attack one tree, it sends a chemical warning through the network. Other trees receive the warning and start producing chemicals that make their leaves taste bad to the insects. In this way, they protect themselves before the insects arrive. Older trees, sometimes called "mother trees", take special care of younger trees. They send extra nutrients to their young through the root network. They even reduce their own root growth to give young trees more space. When a mother tree is dying, it will pass its remaining nutrients to the younger trees around it. Next time you walk through a forest, remember that you are walking through a busy community full of communication and care. ( ) 20. What connects trees in a forest according to the passage? A. Their branches. B. An underground network. C. Their leaves. D. The wind. ( ) 21. What do the fungi get from the trees? A. Water. B. Nutrients. C. Sugars. D. Oxygen. ( ) 22. How do trees warn each other about insects? A. By making loud sounds. B. By sending chemical signals through the network. C. By shaking their leaves. D. By changing their colours. ( ) 23. What do mother trees do for young trees? A. They take water from them. B. They send extra nutrients to them. C. They stop them from growing. D. They push them away. 第三篇 阅读下面短文,根据短文内容选择最佳答案。(共4小题;每小题2分,满分8分) Flamingos are some of the most striking birds in the world. With their long legs, curved necks, and bright pink feathers, they look like something from a fairy tale. But what makes them pink? The answer lies in their diet. Flamingos are not born pink. Baby flamingos are actually grey or white. As they grow, their feathers slowly turn pink. This happens because of what they eat. Flamingos feed mainly on tiny creatures called brine shrimp and blue-green algae. These contain special pigments called carotenoids. The flamingo's body breaks down these pigments and uses them to colour its feathers. The more carotenoids a flamingo eats, the pinker it becomes. Flamingos live in large groups called colonies. Some colonies can have over one million birds! Living in such large groups helps protect them from predators. When a predator comes near, the whole colony can take off together, creating a beautiful pink cloud in the sky. Flamingos are also known for their unusual way of eating. They feed with their heads upside down in the water. They use their curved beaks to filter tiny food from the water. Their beaks work like a sieve, letting water out but keeping the food in. These beautiful birds remind us how creative nature can be. From their colour to their eating habits, everything about flamingos is wonderfully unique. ( ) 24. What colour are baby flamingos when they are born? A. Bright pink. B. Grey or white. C. Light blue. D. Dark red. ( ) 25. What makes flamingos turn pink? A. The sun. B. The water they drink. C. The food they eat. D. The air they breathe. ( ) 26. How do flamingos protect themselves from predators? A. By hiding in trees. B. By living in large groups. C. By swimming deep underwater. D. By building strong nests. ( ) 27. How do flamingos eat their food? A. With their heads upside down in the water. B. By catching fish with their beaks. C. By diving deep into the water. D. By waiting for food to come to the surface. 第四篇 阅读下面短文,根据短文内容选择最佳答案。(共5小题;每小题2分,满分10分) Have you ever looked closely at a spider's web? These silky creations are not only beautiful but also incredibly strong. In fact, spider silk is one of the strongest natural materials on Earth. Weight for weight, it is stronger than steel. Spiders produce silk from special organs called spinnerets. They can produce different types of silk for different purposes. Some silk is sticky to catch prey, while other silk is stronger and used to build the frame of the web. The most amazing thing is that spiders recycle their silk. When a web is damaged, the spider eats the old silk and uses the protein to make new silk. Not all spiders spin webs. Some spiders hunt by jumping on their prey. The jumping spider can leap up to 50 times its own body length. It does not make a web to catch food, but it always leaves a silk line behind it when it jumps. This line acts like a safety rope. If the spider misses its target, it can climb back up the line. Spiders play a very important role in nature. They eat large numbers of insects, including many that harm crops and spread diseases. Without spiders, we would have many more pests in our gardens and homes. Scientists estimate that spiders around the world eat between 400 and 800 million tons of insects every year. Despite their scary appearance, most spiders are harmless to humans. They are amazing architects, hunters, and helpers in nature. Next time you see a spider, try to admire it rather than fear it. ( ) 28. How strong is spider silk compared to steel? A. It is as strong as steel. B. It is stronger than steel weight for weight. C. It is weaker than steel. D. It has no strength at all. ( ) 29. What do spiders do with damaged silk? A. They leave it and build a new web. B. They give it to other spiders. C. They eat it and reuse the protein. D. They throw it away. ( ) 30. How far can a jumping spider leap compared to its body length? A. Up to 10 times. B. Up to 30 times. C. Up to 50 times. D. Up to 100 times. ( ) 31. How many insects do spiders eat worldwide every year? A. Between 100 and 200 million tons. B. Between 200 and 400 million tons. C. Between 400 and 800 million tons. D. Between 800 and 1,000 million tons. ( ) 32. What does the writer want to tell us in this passage? A. Spiders are dangerous and should be killed. B. Spiders are amazing creatures that help nature. C. Spiders only spin webs to catch insects. D. Spiders are stronger than all other animals. 三、语言知识运用(共两节,满分25分) 第一节 完形填空(共10小题;每小题1.5分,满分15分) 阅读下面短文,从短文后各题所给的A、B、C、D四个选项中,选出可以填入空白处的最佳选项。 Have you ever heard of bioluminescence?

It is so big that it can be seen from space. The reef is home to over 1,500 kinds of fish and many other sea creatures. The colours of the coral and fish are so beautiful that it looks like an underwater garden. Sadly, the reef is in danger because of climate change and pollution. Warmer ocean temperatures are causing the coral to turn white and die. I really hope to visit the Great Barrier Reef one day before it disappears. I also want to learn more about how to protect it. 二、阅读理解 第一篇 16-19: B B B C 第二篇 20-23: B C B B 第三篇 24-27: B C B A 第四篇 28-32: B C C C B 三、语言知识运用 第一节 完形填空 33-37: B C A C B 38-42: A C A B C 第二节 补全对话 43-47: C D F A B (选项E为多余项) 四、语法填空 48. millions 49. survival 50. called 51. on 52. currents 53. for 54. becoming 55. their 56.

Now let me tell you about one of them. I want to tell you about Zhangjiajie National Forest Park. It is in Hunan Province. The park is famous for its tall sandstone pillars that look like they are floating in the clouds. These strange rock formations were formed over millions of years. Some of them are over 1,000 metres tall. When you walk in the park, you feel like you are in a different world. It is also home to many rare animals and plants. I visited Zhangjiajie last year with my family. I was amazed by its beauty. I hope you can visit it someday too. Yours, Wang Tao 学科网(北京)股份有限公司 $
