听力原文： All warm-blooded animals are very helpless at first. Young birds and young bats must be taught to fly. Thousands of young seals drown every year. They never learn to swim "naturally." The mother has to take them out under her flipper and show them how. Birds sing without instruction; however, they do not sing well unless they are able to hear older members of their species. Older harvest mice build better nests than beginners. Frank Buck says that the young elephant does not seem to know at first what his trunk is for. It gets in his way and seems more of a hindrance than a help until his parents show him what to do with it. Insects, seem to start life equipped with all necessary reflexes, but they seem to improve their talents with practice. Young spiders, for example, begin by making quite primitive little webs. They attain perfection in their art only after much time. Older spiders, if deprived of their spinnerets, will take to hunting.

听力原文：M: How are your new neighbors, Alison？
W: They seem nice enough, but they have a son who is driving me crazy.
M: What do you mean？
W: He comes home every night around 10 with his car window rolled down and radio blaring. It stops as soon as he turns his car off, but by then, the kids are wide awake.
M: Oh, no.
W: Oh, yes. Sometimes it takes me an hour just to get them to settle down again.
M: Have you tried talking to them？
W: We haven't even really met them yet, except to say a quick hello. I hate to get off on the wrong foot.
M: You are not going to like them when you do meet them if you keep on complaining.
W: I know, but I feel stupid complaining. It's not as though he's blasting stereo all night.
M: You said yourself it's driving you crazy.
W: Well, you know how early I have to be here at the office. I just don't get enough sleep and neither do the kids.
M: Maybe you could go over sometime with a little gift, a plant for the yard or something. Then you could ask about their son, whether they have other children, and they will be sure to ask about yours.
W: Yes, and then what？
M: And then you could mention that the hardest thing at this stage is getting your kids to go to sleep at night.
W: And keeping them asleep.
M: That's the idea and you should do it soon. The.longer you wait, the harder it will be to do politely.

听力原文：M: We seem to be having this conversation over and over again.
W: You're fight.
M: Look, I know how you feel about my smoking. You don't have to tell me every day.
W: I'm sorry. I worry about you.
M: Let's be honest. There's always going to be a reason. After you graduate, it's going to be hard to find a job, then there will be the stress from just starting a job.
M: OK, I get your point. It's just so hard. You don't really understand because you have never smoked.
W: You need some help. Why don't you go to a doctor？
M: You mean a psychiatrist？
W: No, I don't. I mean a general practitioner. Maybe you can get a patch, or some pills, well, I don't know, something to help you with the withdrawal.
M: Really, I believe I can quit on my own. But I'll think about it. I will.
W: All fight. I won't mention it for a week. Then I want to know your decision. Because if you don't get some help, I need to rethink our plans.
M: You mean you'd break our engagement over this？ I can't believe it!
W: I don't know.
