第5题

Most of us grow up taking certain things for granted. We tend to assume that experts and r

eligious leaders tell us" the truth". We tend to believe that things advertised on television or in newspapers can't be bad for us.

However, encouragement of critical thinking in students is one of the goals of most colleges and universities. Few professors require students to share the professors' own beliefs. In general, professors are more concerned that students learn to question and critically examine the arguments of others, including some of their own beliefs or values. This does not mean that professors insist that you change your beliefs, either. It does mean , however, that professors will usually ask you to support the views you express in class or in your writing.

If your premises (前提) are shaky, or if your arguments are not logical, professors personally point out the false reasoning in your arguments. Most professors want you to learn to recognize the premises of your arguments, to examine whether you really accept these premises, and to understand whether or not you draw logical conclusions. Put it this way. Professors don't tell you what to think; they try to teach you how to think.

On the other hand, if you intend to disagree with your professors in class, you should be prepared to offer a strong argument in support of your ideas. Arguing just for the sake of arguing usually does not promote a critical examination of ideas. Many professors interpret it as rudeness.

In the first paragraph, the writer tries to tell us that people______.

A．easily accept certain things without a second thought

B．grow up through learning certain things in life

C．are forming their views during their growth

D．have strong beliefs in authorities while getting old

听力原文：M: Hey! Jenny, do you want to live a longer life？

W: Why？ Of course! Everyone hopes so.

M: Look, here is some advice given by experts on how to live a longer and happier life.

W: They must tell people to do exercises and keep a healthier diet.

M: Yes. They say 30 minutes of mild exercise a day will increase your life span. You can do things like walking, gardening or taking exercise classes.

W: And we should eat a balanced diet with low calories, cut back on red meat, sugar, coffee, alcohol and salt, and eat more fruit, grains and vegetables.

M: Why？ Jenny, you've read this article'？

W: Not at all. But everyone knows that.

M: Come on! I think there is some valuable advice. For example, they say you should enjoy people more, join some social clubs or groups so that you share your life's joys and sorrows.

W: That makes sense. In this way, we can have more positive attitudes towards life and stay optimistic because we feel we're not alone. What else does this article say？

第10题

听力原文：W: Exercise, exercise, exercise. We hear so much about it these days, yet even th

e experts can't agree on which exercises are best. Now some doctors are strongly encouraging arm exercises.

M: Arm exercises？ Is that because our arms are too fat or flabby？

W: Actually, that's not the main reason. They say that arm exercises are an ideal way to become physically fit.

M: But don't arm exercises raise your blood pressure？

W: That they do. But the article I read mentioned ways to compensate for that.

M: How？

W: By adding leg exercises, so the arms don't do all the work. Ann exercises alone aren't enough to increase metabolism before fatigue sets in. The more of the body that's involved in the exercise, the better.

M: And in turn, I'm sure that there's a greater chance of losing weight.

W: Sounds right to me.

M: So what exercises do the experts recommend？

W: They mentioned quite a few but some of the more popular ones are cycling with special bicycles that make you use both your arms and legs, and walking vigorously while you wear arm weights.

M: I must try that, I like to walk a lot.
