Rice, vegetables and fruit all come from plants. Without them, we would have nothing to eat. Second, plants give us air. They take in the gas we breathe out and give out the gas we need. Third, plants make our world beautiful. A city with trees and flowers is a happy place to live in. Plants also help us in other ways. Trees give us wood, and we use wood to make desks, chairs and paper. Some plants can even make us feel better. Doctors say that looking at green plants helps people feel calm. "A plant is not just a plant," says Miss Zhao, a science teacher. "It is a factory, a doctor and a friend. It works for us every second of the day, and it never asks for anything." 14. What do plants give us according to Paragraph 2? A. They give us money. B. They give us food and air. C. They make noise. D. They take our water. 15. What can we make with wood? A. Desks and chairs. B. Glass and metal. C. Plastic and paper. D. Cloth and shoes. 16. How do green plants make people feel? A. They make people feel tired. B. They make people feel cold. C. They make people feel calm. D. They make people feel hungry. 17. What does Miss Zhao compare a plant to? A. It is only useful for food. B. It is like a factory and a friend. C. It asks us for many things. D. It works only in spring. C Plants can do some surprising things. Here are three examples. The first one is the sunflower. Young sunflowers turn their heads to follow the sun during the day. At night, they turn back to the east and wait for the sun to rise again. The second one is the bamboo. Bamboo can grow very fast. Some kinds of bamboo grow almost one metre in a single day. That is why people use bamboo to make fences and baskets — it grows again quickly after you cut it. The third one is the cactus. Cactuses live in dry places. They store water in their thick stems, so they can live for months without rain. "Plants cannot walk," says a gardener. "But they can do many things that we cannot do. They are much cleverer than we think." 18. What do young sunflowers do during the day? A. To follow the sun. B. To find water. C. To hide from birds. D. To make seeds. 19. What is special about bamboo? A. It can live without water. B. It can move by itself. C. It can grow very fast. D. It can eat insects. 20. Where do cactuses store water? A. In their leaves. B. In their thick stems. C. In their flowers. D. In their roots. 21. What does the gardener say about plants? A. They can walk slowly. B. They need no water. C. They are not useful to people. D. They can do things we cannot do. D March 12th is Tree Planting Day in China. This year, our class did something special. Two weeks before that day, our teacher showed us a video about deserts. In the video, the land was yellow and dry. "Trees can stop the desert from growing," the teacher said. "Will you help?" We all put up our hands. On March 12th, we went to a hill outside the city. A worker taught us how to plant a young tree. "Dig a hole, put the tree in, and fill the hole with soil," he said. "Then water it well." It was hard work. My hands were dirty, and my back hurt. But when I looked at the small tree standing in the ground, I felt proud. "This tree will grow," I thought. "In ten years, it will be tall. Maybe some birds will build their homes in it." On the way home, our teacher said, "You planted more than a tree today. You planted hope." 22. When is Tree Planting Day in China? A. March 12th. B. March 2nd. C. April 12th. D. May 12th. 23. What did the class do this year? A. They watched a video. B. They went to a museum. C. They planted trees on a hill. D. They visited a farm. 24. What did the worker teach them to do? A. Dig a hole. B. Water the tree. C. Fill the hole with soil. D. All of the above. 25. What did the teacher say at the end? A. They planted only one tree. B. The work was very easy. C. The hill was near the school. D. They planted hope. 三、任务型阅读（共5小题，每小题3分，满分15分。） 阅读下面短文，根据短文内容完成各小题的任务。 Do you want to grow a plant at home? It is not difficult. Follow these four steps. Step one: choose the right plant. If your room is bright, you can grow a sunflower. If your room is dark, a cactus is a better choice. Cactuses do not need much sunlight. Step two: get a pot and some soil. The pot should have a small hole at the bottom, so extra water can go out. Put the soil in the pot, but do not fill it to the top. Step three: plant the seed. Make a small hole in the soil with your finger. Put the seed in and cover it with soil. Water it a little. Do not water it too much. Step four: take care of it. Most plants need water two or three times a week. Put the pot near a window so it can get sunlight. Be patient — some seeds need two or three weeks to come up. Remember: a plant is a living thing. If you take care of it, it will grow and make your room beautiful. 26. What kind of plant is better for a dark room? 27. Why should the pot have a small hole at the bottom? 28. 根据短文内容，完成下面的四步梳理，每空不超过3个词。 Step 2: get a pot and some ①______. Step 4: ②______ of it. 29. How often do most plants need water? Answer in no more than 10 words. 30. Would you like to grow a plant? Why? Write at least 20 words. 四、补全对话（共5小题，每小题2分，满分10分。） 根据对话内容，从方框内所给的七个选项中选出五个恰当的句子补全对话，使对话意思完整、通顺。 A.
