听力原文： New research from Australia shows that pets are good for your health. The findings of this new study suggest that people who have pets are at less risk from heart disease than those who do not.
The new research was carried out over three years and examined 3,000 people. They took tests that measured a variety of different factors known to be involved in heart disease--blood pressure and blood levels. Also, people were asked about their lifestyles. The 800 people who owned pets had low levels on each of the factors measured than those who did not own pets. The study 'also showed that it did not matter what kind of pet was owned--a cat was as good as a dog— so the benefits could not be attributed to the exercises involved in walking a dog.
The question is just how pets manage to make their owners more healthy. The obvious answer is that they make their owners feel more relaxed and happy. The Australian scientists who organized this study commented that if a new drug was available that was as effective as simply having a pet, then this drug would undoubtedly be considered a breakthrough in the control of heart disease.

W: I didn't say that. I mean, 'if you enjoy it, why not？ What happened to your old TV, anyhow？

W: It must've been expensive.
M: Well, not as much as you might think. I got it on sale for 50% off.
W: Really？ Where？
M: At the stereo city on Route 20. You know at first I just wanted to replace what I had. A TV of about the same size and quality. But the salesman was pushing these because of the 50% off.
W: Yeah. But 50% off what？
M: $ 2,400.
W: You spent $ 1,200 on a TV？
M: It's got a lot of special features. Look at this remote control.
W: I'm sure. But that's still a lot of money for a television. I didn't think you watched TV that much.
M: Well, I don't. Do you think I ought to return it？ If I do it within a week of purchase, I can get my money back.
W: Honestly, yes. And you know that. I think you ought to read up on TV's first and choose the make and model you want before you go to the store. That way you will get what you want.
M: I think you are right.

听力原文： When young people get their real jobs, they may face a lot of new, confusing situations. They may find that everything is different from the way things were at school. It is possible that they will feel uncomfortable in both professional and social situations. Eventually, they realize that university classes can't be the only preparation for all the different situations that appear in the working world.
Perhaps the best way to learn how to behave in the working world is to identify a worker you admire and observe his behavior. In doing so, you'll be able to see what it is that you admire in this person. For example, you will observe hew he acts in trouble. Perhaps even more important, you will be able to see what is his approach to everyday situations.
While you are observing your colleague, you should be asking yourself whether his behavior. is like yours and hew you can learn from his response to a different situation. By watching and learning from a model, you will probably begin to identify and get good working habits.
