It lives in the mountains of central China, mainly in Sichuan, Shaanxi, and Gansu provinces. Pandas are famous for their black and white fur. Their round faces and big black eye patches make them look very cute. Bamboo is the main food of giant pandas. An adult panda eats about 10 to 20 kilos of bamboo every day. That means they spend about 12 to 16 hours a day eating. Pandas also eat other plants and occasionally small animals, but bamboo makes up about 99% of their diet. Giant pandas are solitary animals. They usually live alone except during the breeding season. A baby panda is born very tiny, weighing only about 100 grams. That is about the size of a mouse. The mother panda takes good care of her baby for about 18 months. The number of giant pandas in the wild has been increasing in recent years. Thanks to the hard work of scientists and the Chinese government, there are now about 1,900 pandas living in the wild. However, we still need to continue protecting them and their homes. ( ) 16. Where do giant pandas live? A. In the forests of northeast China. B. In the mountains of central China. C. In the deserts of northwest China. D. In the grasslands of southern China. ( ) 17. How much bamboo does an adult panda eat every day? A. About 5 to 10 kilos. B. About 10 to 20 kilos. C. About 20 to 30 kilos. D. About 30 to 40 kilos. ( ) 18. What does the underlined word "solitary" mean? A. 群居的 B. 独居的 C. 友好的 D. 胆小的 ( ) 19. How many giant pandas are living in the wild now? A. About 1,000. B. About 1,500. C. About 1,900. D. About 2,500. 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） Bees are truly amazing insects. They live in highly organised groups and work very hard. A bee colony can have up to 60,000 bees. Each bee has a specific job. Worker bees collect nectar and pollen from flowers. They also take care of the young bees and protect the hive. The queen bee has only one job—laying eggs. She can lay up to 2,000 eggs in a single day. Bees are very important to our planet. When they fly from flower to flower to collect nectar, they carry pollen with them. This process is called pollination. Without bees, many plants would not be able to grow fruits and seeds. In fact, about one-third of the food we eat depends on bees for pollination. Sadly, the number of bees around the world is dropping rapidly. Scientists believe this is caused by several reasons, including the use of pesticides, loss of wild flowers, and climate change. If bees disappear, our food supply would be in great danger. That is why many countries are now taking action to protect these tiny but important creatures. ( ) 20. How many bees can live in one colony? A. Up to 6,000. B. Up to 20,000. C. Up to 60,000. D. Up to 100,000. ( ) 21. What is the queen bee's main job? A. Collecting nectar. B. Protecting the hive. C. Laying eggs. D. Taking care of young bees. ( ) 22. Why are bees important to plants? A. They eat harmful insects. B. They help with pollination. C. They make the soil better. D. They provide food for birds. ( ) 23. What would happen if bees disappeared? A. More flowers would grow. B. Our food supply would be in danger. C. Farmers would use less pesticide. D. The weather would become warmer. 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） The ocean is full of amazing creatures, but few are as strange and beautiful as jellyfish. These umbrella-shaped animals have lived in the sea for more than 500 million years—long before dinosaurs appeared on Earth. Jellyfish are not actually fish. Their bodies are made up of about 95% water, and they have no brain, no heart, and no bones. Yet they are excellent survivors. They can be found in every ocean, from the surface to the deep sea. One of the most amazing types is the immortal jellyfish. When this tiny jellyfish gets hurt or becomes very old, it can turn back into its younger form. It is like a butterfly turning back into a caterpillar. Scientists are studying this creature carefully, hoping to understand the secret of its long life. Some jellyfish can glow in the dark. This ability is called bioluminescence. They produce light through a chemical reaction in their bodies. When thousands of these jellyfish glow together in the deep, dark ocean, it looks like a starry night sky under the water. ( ) 24. How long have jellyfish lived on Earth? A. For about 100 million years. B. For about 300 million years. C. For more than 500 million years. D. For about 1 billion years. ( ) 25. What makes the immortal jellyfish special? A. It can glow in the dark. B. It can turn back into its younger form. C. It can live without water. D. It has a very large brain. ( ) 26. What is bioluminescence? A. The ability to change colour. B. The ability to swim very fast. C. The ability to produce light. D. The ability to live forever. ( ) 27. Where can this passage probably be found? A. In a travel guide. B. In a nature magazine. C. In a history book. D. In a cookbook. 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） Ants are tiny creatures, but they are some of the most successful animals on Earth. Scientists have discovered more than 12,000 species of ants, and they live almost everywhere except in the coldest places. Ants live in colonies that are like small cities. Some colonies have millions of ants. In an ant colony, every ant has a job. The queen lays eggs. Worker ants build the nest, find food, and take care of the babies. Soldier ants protect the colony from danger. The whole colony works together like a well-organised team. One amazing thing about ants is their strength. An ant can carry objects that are 10 to 50 times heavier than its own body weight. That is like a human lifting a car! They are also very good at working together. When they find a piece of food that is too big for one ant, they call other ants for help. Soon, a long line of ants will carry the food back to their nest. Ants are also "farmers" in a way. Some species of ants grow fungi for food. Other ants keep aphids, tiny insects that produce a sweet liquid the ants love to eat. The ants protect the aphids from other insects and "milk" them for this liquid. Ants may be small, but they teach us a big lesson about the power of teamwork. ( ) 28. How many species of ants have scientists discovered? A. Over 1,200. B. Over 12,000. C. Over 120,000. D. Over 1,200,000. ( ) 29. What is the job of soldier ants? A. Laying eggs. B. Finding food. C. Protecting the colony. D. Building the nest. ( ) 30. How much can an ant carry compared to its own body weight? A. 2 to 5 times. B. 5 to 8 times. C. 10 to 50 times. D. 100 to 200 times. ( ) 31. How do some ants get sweet liquid? A. They make it from flowers. B. They keep aphids and "milk" them. C. They steal it from bees. D. They find it in river water. ( ) 32. What lesson does the writer think ants teach us? A. The importance of being strong. B. The value of working alone. C. The power of teamwork. D. The need to build bigger cities. 三、语言知识运用（共两节，满分25分） 第一节 选出不同类的一项（共5小题；每小题1分，满分5分） 从A、B、C、D四个选项中，选出与所给单词不同类的一项。 ( ) 33. A. panda B. tiger C. elephant D. forest ( ) 34.

Halfway up, we stopped to rest near a small stream. The water was so clear that we could see the stones at the 42 . My younger sister wanted to drink the water, but the guide said it was not 43 because there might be tiny creatures in it. Suddenly, we heard a strange sound from the trees. We looked up and saw a group of golden monkeys 44 from branch to branch. They moved so fast that it was 45 to follow them with our eyes. The guide said we were very lucky because these monkeys are rare and usually 46 from people. That trip taught me to love and respect 47 .
