Take a close look at the world of insects, you’ll discover many wonderful things. Take butterflies, for example. They have beautiful, colourful wings, and strong, fantastic flying skills. On summer days, you always see them flying freely over flower gardens and fields. But did you know how butterflies become the flying insects? It’s one of the amazing wonders of nature. In the beginning, female (雌的) butterflies lay a small and colourful egg on a leaf or stem (茎) of a plant. It’s hard to believe that the egg will become something quite different in a few days. It becomes a walking insect. This insect is called caterpillar (毛虫). It now has legs, eyes and a large body. A new life has begun. The caterpillar can eat, walk and see. But it is still not a butterfly. Soon, after growing big, the caterpillar makes a cover for itself. It covers itself in the nice protective blanket (保护层) and goes to sleep. This stage is “pupa (蛹)” stage. After some time, the blanket breaks and a wet butterfly appears. It now has six legs, a mouth, two eyes and four wings. Later, the colourful butterfly flies away. After a few weeks, this butterfly lays her eggs, and the process begins again. This is just one example of the wonders of nature. Look around the natural world, and you will learn many amazing things. ( )19. What is NOT mentioned in Paragraph 1? A. Butterflies are a kind of insect. B. Butterflies are good at flying. C. Butterflies have colourful wings. D. Butterflies have a good sense of smell. ( )20. What is the right order of the development process of a butterfly? ① It becomes a pupa. ② It becomes a walking insect. A female butterfly lays an egg. ④It flies away. A. ①②③④ B. ①②④③ C. ③②①④ D. ③②④① ( )21. Which of the following best describes a butterfly after the blanket breaks? A. It has legs, eyes and a large body. B. It has legs, eyes and a mouth. C. It has six legs, a mouth, two eyes and four wings. D. It has legs, eyes, a mouth and a large body. ( )22. What can be the best title for the text? A. One Insect, Different Colours B. One Insect, Four Lives C. The Kinds of Butterflies D. The Habits of Butterflies C Our earth has two very cold areas at its ends: the Arctic and the Antarctic. The Arctic is the area around the North Pole (极), while the Antarctic is the area around the South Pole. They have a lot in common, but they are also different in many ways. The two places are very cold and ice covers them. Much of the ice there never melts (融化). One big difference is what is under the ice. Water is under most of the ice in the Arctic. However, land is under most of the ice in the Antarctic. Antarctica is a large continent (大陆). It has mountains, valleys and plains (平原). The Arctic is warmer than the Antarctic. Plants grow in the Arctic in summer. The Antarctic has almost no plants because it is too cold. Only a few small plants grow there each summer. Animals live in both places. Polar bears, for example, live in the Arctic. So do some foxes and wolves. Most animals cannot live in Antarctica because it is too cold. However, penguins can live there. Some animals, such as whales, can live in both places. Many people live in the Arctic. There are towns and small cities in the land areas. However, the Antarctic is so cold that no one can live there for long. Scientists who study the continent only stay there while they are working. They live in special buildings and don’t spend much time outside. ( )23. What’s Paragraph 2 mainly about? A. The freezing weather in both places. B. How the ice can stay there for so long. C. Where the ice in both places comes from. D. Reasons for the terrible weather in both places. ( )24. What does the underlined word “It” in Paragraph 3 refer to? A. The Arctic. B. The Antarctic. C. The earth. D. The ice. ( )25. What can we learn from the text? A. Scientists can stay in the Antarctic for a long time. B. Penguins are the only animals living in the Antarctic. C. The summer temperatures help the Arctic plants to grow. D. No ice melts in the Arctic or the Antarctic all year round. ( )26. What is the purpose of the text? A. To explain the importance of saving water. B. To tell us the Arctic and the Antarctic have a lot in common. C. To help scientists learn more about the Arctic and the Antarctic. D. To describe the similarities and differences between the Arctic and the Antarctic. D 1 Can you imagine a sea of sand almost three times bigger than India? This is the Sahara, the largest desert in the world. It covers more than 10 countries in North Africa and is about 9 million square kilometres. That’s more than of Africa. 2 In the Sahara, temperatures are very different during the day and at night. It is much hotter during the day than at night. During the day, the hottest time is between 12:00 p.m. and 3:00 p.m., when temperatures rise to . But it is very cold at night — the coldest temperatures fall to . The Sahara is very dry. The precipitation (降水量) in a year is only about 76 millimetres. Because of the extreme (极度的) temperatures in the desert, it is a very difficult place to survive. However, here are some tips from experts. ③ ▲ You will need a hat, long trousers and a coat to keep you warm at night. During the day, cover your body, head and face. Clothes protect you from the sun and keep water in your body. You will also need a warm blanket (毯子) at night. It can get cold very quickly. When the temperature drops, it can be a shock and make you feel even colder. A car is easier to see than a person walking in the desert. You can use the mirrors from your car to make planes and other cars notice you. You can use your cart tyres (轮胎) to make a fire. A fire is easy to see. It will help people find you and it will keep you warm at night. ⑤ Try to drink some water at least once every hour. Drink only what you need. When you talk, you lose water from your body. Keep your mouth closed and do not talk. If you eat, you will get thirsty and drink all of your water quickly. You can eat a little, but only to stop you from feeling very try. Eat very little food and eat very slowly. You can live for three weeks with no food, but you can only live for three to five days without water. ⑥ It is very important to stay out of the sun during the day. Make a hole (洞) under your car and lie there. This will keep you cool and help you sleep. Find a warm place to sleep at night. A small place near a tree or a rock will be the warmest. But be careful before you decide where to sleep. Dangerous animals like snakes also like to sleep in these places. Look carefully for animals before you lie down. ( )27. Why does the author write Paragraph 2? A. To explain why the desert is so hot. B. To introduce what size the Sahara is. C. To tell us how difficult it is to stay alive in the Sahara. D. To explain why the precipitation of the Sahara is so little. ( )28. Which of the following can we put into the blank “▲” in Paragraph 3? A. Take warm clothes and a blanket. B. Carry enough fresh water with you. C. It’s better to drive a car there. D. It’s important to know something about first aid. ( )29. Where should we sleep in the Sahara during the day? A. Inside the car. B. Under a big rock. C. In a hole under the car. D. In a small place near a tree. ( )30. Which of the following best shows the structure of the text? 第二节 任务型阅读（共5小题，每小题2分，满分10分） 阅读下面材料，从选项中所给的A—E五个选项中选出正确选项（其中一项是多余选项)，将其序号填入第 小题，并回答第35小题。 After seven years of building, work on the world’s longest high-altitude road tunnel (高海拔公路隧道) at 31.________that time was over on 28th June, 2023 in Xizang.
