听力原文: Good afternoon, everybody. Thank you very much for inviting me here to talk about safety in dormitory and personal security. First, a few points to bear in mind. You'll notice the doors of your dorm have two types of locks, a Yale lock and a Chubb lock. Make sure you double lock your door, not just one lock, both of them, however long you are golng out for. Make sure when you go out, all the windows are closed. Those of you in the ground and first-floor rooms will notice that you are locking windows, make sure you use them. Lock them every time you go out; lock them at night. If you have got expensive equipments in your room, first of all, insure it. So many people lose things and haven't got insurance. Make sure you insure it. This brings me onto personal security. Wherever possible, avoid working alone late at night, especially girl students. Avoid dark streets, and try to stick to the well-lit streets whenever possible. Also if you know you are going to be up late, make sure you've got enough money for a taxi to get home again, or arrange to stay with friends for the night. It may sound absurd, but don't forget the university actually offers free self-defense classes. I hope it something you'd never have to use, but it certainly was going along to a few self-defense sessions.
According to the speaker, safety in dormitory means that you ______ .
A. insure all your expensive things
B. lock doors when going out
C. lock windows at night
D. take all necessary precautions
听力原文:M: We are having a debate on advertising Thursday evening, and I have to take part.
W: That's interesting. I should like to hear what people think about advertising.
M: What's there to say? We must have advertising, mustn't we?
W: Why?
M: Well, we wouldn't know what there was to buy if we didn't have advertisements.
W: Yes, that's true. Up to a point, advertisements provide information that we need. If someone has produced a new article, naturally, the seller wants to tell us about it.
M: Yes, and the advertisements tell us which product is the best.
W: Do they? I don't think so. Every manufacturer says that his product is the best, or at least tries to give the impres-sion. Only one can be the best, so the others are misleading, aren't they?
M: Well, in a way, I suppose, but we don't have to believe them, do we?
W: Are you saying that advertisements aren't effective? I don't think that intelligent businessmen will spend millions of dollars on advertising if nobody believes the advertisements, do you?
M: Perhaps not, but after all, it's their money that they are spending.
W: Is it? I think not. The cost of advertising is added to the price of the article. You and I and all the other people who buy the article pay for the advertising.
M: Well, I suppose we get something for our money, some information.
W: Yes, but don't forget it is often misleading information, and sometimes harmful.
M: Harmful?
W: What about the advertisements designed to persuade young people to smoke cigarettes? Wouldn't you say they are harmful?
M: You've given me a lot to think about. I'm quite looking forward to the debate now.
According to the woman, advertisements ______ .
A. let us know the best product
B. give us sufficient information
C. fail to convince people
D. give misleading information
