B How Students Can Practice Environmental Protection With the development of the world, environmental problems have become more and more serious. As students, we have a responsibility to protect the environment. There are many simple ways we can practice environmental protection in our daily lives. First, we can save paper. Every year, a large number of trees are cut down to make paper. We can use both sides of a piece of paper when doing homework or taking notes. We can also reuse old notebooks by using the blank pages. In addition, we can send e-mails instead of writing letters to our friends, which can save a lot of paper. Second, we can save electricity. We should turn off the lights, computers and air conditioners when we leave the classroom or our rooms. We can also use energy-saving bulbs, which use less electricity than ordinary bulbs. During the day, we can open the curtains to let in natural light instead of turning on the lights. Third, we can reduce waste. We can bring our own shopping bags when going shopping instead of using plastic bags. Plastic bags are harmful to the environment because they take a long time to decompose. We can also separate our waste into different categories, such as recyclable waste and non-recyclable waste. This makes it easier for workers to recycle the waste. Finally, we can plant trees. Trees can absorb carbon dioxide and release oxygen, which is good for the air. Every spring, many schools organize tree-planting activities. We can take part in these activities and plant more trees in our community. Protecting the environment is not a difficult task. It requires our efforts every day. If every student can do a little bit for the environment, we will have a better world. 31. Why should we save paper according to the passage? A. Because paper is expensive. B. Because a lot of trees are cut down to make paper. C. Because we don't have enough paper. D. Because paper is not easy to use. 32. What can we do to save electricity? A. Use ordinary bulbs instead of energy-saving bulbs. B. Keep the lights on when we leave the room. C. Use natural light during the day. D. Keep the air conditioner on all day. 33. Why are plastic bags harmful to the environment? A. Because they are too expensive. B. Because they take a long time to decompose. C. Because they are not easy to carry. D. Because they are not strong enough. 34. What can trees do for the environment? A. They can absorb oxygen and release carbon dioxide. B. They can absorb air and release water. C. They can absorb water and release air. D. They can absorb carbon dioxide and release oxygen. 35. What is the main idea of the passage? A. Environmental problems are very serious. B. Schools should organize more activities. C. Students can practice environmental protection in many simple ways. D. We should plant more trees. C Stop reading for a minute and think about what you see when you look up at the sky on a clear night. You probably see many stars. Long long ago, farmers watched some stars to know when to plant their crops. Travelers did so to find their way in the dark. Today stars are still important to some people. Scientists find that most stars are very big. In fact some stars are so far away that it would take millions of years to get to them even by spaceship. Another thing we know today about stars is that some are made up of(由······组成) hot gases(气体). The gases are so hot that they send out light. If you watch a star carefully, you may notice that it twinkles(闪烁) sometimes. As you may understand, light from a star must shine through the air before you can see the star. Air is always moving, and it makes light from the star move, too. Stars also have different colors. The color of a star depends on how hot it is. To our surprise, the cool stars are red and the hot stars are white. 36. Long long ago, how did travelers find their way in the dark? A. By making a fire. B. By using a lamp. C. By watching stars. D. By using sticks. 37. Why can the gases send out light? A. Because they' re very far away. B. Because they' re very hot. C. Because they have different colors. D. Because they can move. 38. Why does a star sometimes twinkle? A. Because its light travels through the moving air. B. Because its light is too bright. C. Because it is made up of hot gases. D. Because it is too dark. 39. Which of the following is TRUE according to the passage? A. Today stars are not important to people at all. B. It would take us a short time to get to the stars by spaceship. C. You can see a star before its light shines through the air. D. Farmers knew when to plant their crops by watching some stars. 40. What is the main idea of the passage? A. Stars can help travelers find ways at night. B. Stars are all made up of hot gases. C. The passage tells us some information about stars, such as their uses in the past and some scientific facts about them. D. Stars have different colors. 五、补全对话(本大题共5小题，每小题1分，共5分) 根据对话内容，从方框内选择恰当的句子将对话补充完整。(选项中有两项是多余的) A. I agree. B. What else can we do? C. Thanks for your advice. D. I am watching a show on TV. E.

Animal waste and dead bodies are broken down by small creatures(生物), like those worms in the soil. This is their f 63 . The carbon dioxide that people and animals breathe out is used by plants to breathe and help them g 64 . Plants give out oxygen which people and animals need to breathe in. Plants take in w 65 through their roots. They pass it out through their leaves as moisture(水分). This moisture, together with water vapour coming f 66 rivers and seas, rises and turns into water droplets and forms clouds. Larger water droplets then f 67 down in the form of rain. In this way, the water goes b 68 to the earth, rivers and seas to be used again. However, humans have made a lot of changes to the earth. The technology and industry have made life e 69 , but they also produce a lot of new waste. Nature finds this new waste hard or i 70 to recycle.

The natural world belongs to all of us. I think everybody should take on the responsibility of environmental protection. There are many environmental problems nowadays. Trees are cut down for production and rubbish is often thrown into rivers and lakes. Luckily, there are many things we can do to protect the natural world. We should sort the rubbish into different groups so that it can be reused and recycled better. Besides, we should learn to save energy, such as not leaving taps running all the time. Let's take action to save our world together！ That's all. Thanks for your listening. 学科网（北京）股份有限公司 $
