听力原文： Spaceships travel around the earth, go to the moon, and return home safely. The astronauts carry important supplies with them on the spaceship — food, water and air. Sometimes there are problems on the spaceship, and the astronauts have to understand how the spaceship works in order to repair the problems. In a way, all of us are really on a spaceship, the planet Earth. We move around the Sun at 18 miles per second and never stop. On our spaceship we have four billion people and a limited supply of air, water and land. These supplies, just like the limited supplies on the astronauts spaceship, have to be used carefully because we cant buy new air, water or land from anywhere else. Everyone needs air, water and land to live — this is our environment. The environment on our planet is a closed system; nothing new is ever added. Nature recycles its resources. Water, for example, evaporates and rises to form. clouds. This same water returns to the earth as rain or snow. The rain that falls today is actually the same water that fell on the dinosaurs 70 million years ago. Over the years, people have changed the environment. We have poured back into the land, air, and water more wastes than nature can clean. So we have pollution today. To continue to survive, we must learn how to use the Earths resources wisely, without destroying them. To save the spaceship Earth, we must cooperate with nature and learn better ways to use, not to abuse our environment. Questions 20 to 22 are based on the passage you have just heard. 20.

听力原文：M: Here is the summer vacation again. It seems that there is no new place in our country for me to travel. W: I have an idea to make good use of our vacations. We have benefited from the society but done nothing in return. Do you want to do some local voluntary work for the society this year？ M: Sounds interesting. What do you think we should do？ W: Im not sure. Maybe we could offer help in the hospital for handicapped children. We could help feed the children and help look after them. M: Excellent! But Im not sure if we will be allowed to do that. I think all helpers there have to be specially trained. And we are not in the related major. W: Yeah, maybe you are right. I still have the idea of doing something for children, havent you？ M: Well, maybe. And I think many old people also need help. What else did you have in mind for children？ W: My other idea was to do something for the small primary school down the street. That school is too poor to provide a playground for the pupils. Children cannot do without one. Ive noticed that some land round the back of the school is not used. We could make it into a small playground. What do you think？ M: Mm, its a good idea, but you are a bit too ambitious. I dont know anything about making playgrounds. And I also think that it might be too expensive to do what you suggest. W: Yes, I guess youre right. We cannot afford the big project unless someone sponsors us. Its impossible for us to find such a person. So what do you have in mind for older people？ M: I think we should go round to the homes of older people and ask if there is something we can do in the house — you know, like a bit of simple decorating, washing the clothes, cleaning up the garden, even doing some shopping for them once a week. W: Mm, this sounds meaningful and practical. I quite like the idea. It wont cost us any money and Im sure we are capable of dealing with the things you mentioned. Questions 9 to 12 are based on the conversation you have just heard. 9. What are the two speakers arrangements for the coming summer vacation？ 10. What can we learn about the woman from the conversation？ 11. Why cant they make a playground for the pupils？ 12. What are the possible identities of the two speakers？9．
