But there is another kind of pollution that is hard to see—light pollution. Light pollution is the bright light that humans create at night. It comes from street lights, advertising signs, and buildings. Many people think that bright lights are good because they make streets safe. However, for animals, these lights are a big problem. Birds use the stars to find their way when they travel at night. If there are too many bright lights in the city, they will lose their way and even crash into buildings. Sea turtles (海龟) also suffer. When baby sea turtles are born, they use the moon to find the sea. But bright lights from the beach make them go the wrong way. What can we do to reduce light pollution? First, we can turn off the lights that we don't need. Second, we can use less bright lights in parks and on streets. Third, we can close the curtains (窗帘) at night to stop the light from getting outside. It is important to protect nature. If we can see the stars again in the city, it means we are making a difference. ( ) 41. What is light pollution according to the passage? A. The light from the sun. B. The bright light that humans create at night. C. The light from the moon and stars. D. The light from the sea. ( ) 42. How does light pollution affect birds? A. It makes them find food easily. B. It helps them travel at night. C. It makes them lose their way and crash. D. It makes them sing loudly at night. ( ) 43. Why do baby sea turtles go the wrong way? A. Because they want to play on the beach. B. Because they are afraid of the sea. C. Because the bright lights from the beach trouble them. D. Because they use the stars to find the sea. ( ) 44. Which is NOT mentioned to reduce light pollution? A. Turn off the unnecessary lights. B. Use less bright lights in parks. C. Close the curtains at night. D. Never use street lights. ( ) 45. What is the best title for this passage? A. How to Protect the Birds B. The Danger of Light Pollution C. The Sea Turtles' Journey D. The Stars in the City C篇 阅读下面短文，回答问题。 Many people believe that the world's biggest problem is the growing population. However, there is another problem that is more dangerous—the loss of nature. Humans are cutting down forests and polluting rivers. We are taking away the homes of many animals. As a result, some animals are disappearing. We are losing the balance of nature. In the past, humans lived in harmony with nature. But now, we want to control (控制) everything. We build huge cities and roads. We damage the environment. In the end, we are hurting ourselves. The pollution we create makes us sick. So, what can we do? We need to stop destroying nature. We should protect the natural wonders that are left. We can plant more trees and clean up the rivers. The most important thing is that we must change our minds. We need to know that we are not the masters (主人) of the earth. We are just a part of it. As the famous writer Montaigne once said, "Let us permit nature to have her way." 46.What is the more dangerous problem mentioned in the passage? 47.What are the results of humans cutting down forests and polluting rivers? 48.Why do humans get sick according to the passage? 49.
