听力原文：M: Today, I'm interviewing a young girl named Alex about her feelings on how people can help save the environment. So, Alex, how can we save the environment？
W: By saving water.
M: Well, how can we do that？
W: By not using too much water when we wash dishes, take a bath, and when we do other things, like watering the plants outside.
M: Oh, I think I can do that. What else？
W: When drinking or eating something outside, you should keep the garbage until you find a trashcan to put it in because littering makes our planet dirty. Do you like seeing trash all over the ground？
M: No, I don't. Do you have any final suggestions？
W: Yes. We shouldn't waste paper because trees are being cot down to make the paper. By recycling paper, we save the forests where animals live.
M: So, how can people recycle paper, I mean, everyday？
W: Well, for example, when I was in the office, I used to save the newspapers so that I could collect things made out of them, like paper trees, instead of just throwing them away. Now, the children in our neighborhood collect newspapers once a month to take them to a recycling center.
M: That's great. Well, thanks Alex for your ideas.
