Here's a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be   1  for your health. And it doesn't matter where the sitting takes place — at the office, at school, in the car or before a computer or TV — just the overall number of hours it   2   .

Research is preliminary, but several studies   3  people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.

In an editorial   4  this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define   5  activity to highlight the dangers of sitting.

While health officials have issued guidelines   6  minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated   7  .

"After four hours of sitting, the body starts to send   8  signals," Ekblom-Bak said. She explained that genes regulating the amount of glucoseand fat in the   9  start to shut down.

Even for people who   10   , spending long stretches of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day —   11  still spend a lot of time sitting — might get more benefit if that exercise were spread across the day,    12  in a single bout.

That wasn't   13  news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting    14   a computer. Several evenings a week, Can also teaches jiu jitsu, a Japanese martial art  15  wrestling, and also does Thai boxing.

"I'm sure there are some detrimental   16  of staying still for too long, but I hope that being   17  when I can helps," he said. "I wouldn't want to think the sitting could be   18  dangerous."

Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat   19  had a higher death risk, independently of whether or not they exercised.

Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars.

Experts said more research is needed to    20  just how much sitting is dangerous, and what might be possible to offset those effects.

What will man be like in the future—in 5000 or even 50, 000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time.

Let us take an obvious example. Man, even five hundred years ago , was shorter than he is today. Now, on average,  men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modem world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’ s capacity(容量). As time goes on , however , we shall have to use our brains more and more,  and eventually we shall need larger ones! This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact , we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’ s eyes will grow stronger.

On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however , our fingers will grow more sensitive（敏感的） because they are used a great deal in modern life.

But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.

Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. …

1.The passage mainly tells us that _______.

A．man’s life will be different in the future.

B．future man will look quite different from us.

C．man is growing taller and uglier as time passes.

D．human’s organs’ functions will become weak “

2.The change in man’s size of forehead will probably be because ___________.

A．he makes use onIy20% of the brain’s capacity.

B．his brain has grown larger over the past centuries.

C．the other 80% of his brain will grow in due time

D．he will use his brain more and more as time goes on :

3.What will be true about a human being in the future?

A．He will be hairless because hair is no longer useful.

B．He will have smaller eyes and will wear better glasses.

C．His fingers will grow weaker because he won’t have to make use of them.

D．He will think and feel in a different way.

4.It is implied that ________.

A．human beings will become less attractive in the future

B．less use of a bodily organ may lead to its degeneration(退化,)

C．human beings hope for a change in the future life

D．future life is always predictable

Love and Friendship

   They are both so much related to each other. And both are so dissimilar! What are the differences between friendship and love? Is platonic(柏拉图式的) friendship possible between persons of the opposite sex? _1. _

     What is friendship? Why do we call a person our friend? When do we call someone a very good friend? If we care for a person, if we are always ready to help that person and if we share most of our thoughts with a person, they are our good friends. We can always count upon our good friends in an emergency. We are always sure that our friends will understand why we acted in a certain way. 2. The friendship is so deep and the relationship is so intimate, that most of the things are automatically understood by our friends.

    _3. _ In a relationship of deep love, all the sharing that we discussed above is taken for granted. But love transcends(超出) all this. During love, we are attached with a particular person, while in friendship, one may have many friends. A loving relationship makes one so much attached to the other that one gets pained if his/her beloved is hurt! Love also involves a physical element. __4. __ This is a vital difference. Nature gives us love so that the species can go forward. Nature does not give us friendship.

    Your heart beats will never increase in anticipation of meeting your friend. _5. __ You will not feel totally lost, if you don’t meet your friend for a few days. You will not have dreams in your eyes thinking about your friend. But in love, you will do all this and much more. Indeed, there is no comparison between love and friendship.

A.What about love?

B.My answer is “Yes”.

C.Let us try and understand.

D.Friendship does not have that.

E.We need not explain anything to our very good friends.

F.You will not lie awake at night thinking about your friend.

G.The physical element may include hand in hand while walking.
