听力原文：M: Today, I'm interviewing nine-year-old Carol about her feelings on how people can help save the environment. Good evening, Carol.
W: Good evening, I'm glad to be here.
M: So, Carol, 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: We should try to make our environment tidy.
M: What can we do?
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 cut down to make the paper. By recycling paper, we save the forests where animals live.
M: So, how can children recycle paper, I mean, everyday?
W: Well, for example, when I was in kindergarten, I used to save the newspapers so that I could make things out of them, like paper trees, instead of just throwing them away.
M: Good idea! What do you do now?
W: Now, the children in our neighbourhood collect newspapers once a month to take them to a recycling centre.
M: That's great. Well, thanks Carol for your ideas.
W: You're welcome.
