9、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 glucose and 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．

8、Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours．This kind of loneliness is not serious．In fact, it is quite normal．For some people, though, loneliness can last for years．Now researchers say there are three different types of loneliness．

       The first kind of loneliness is temporary（暂时的）．This is the most common type．It usually disappears quickly and does not require any special attention．The second kind, situational loneliness, is a natural result of a particular situation--- for example, a family problem, the death of a loved one, or moving to a new place．Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year．The third kind of loneliness is the most severe．Unlike the second type, chronic（长期的）loneliness usually lasts more than two years and has no specific cause．People who experience habitual loneliness have problems socializing and becoming close to others．Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition．

       Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease．While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition．

1．How would you treat temporary loneliness according to the passage ?

       A．Talk to friends．                           B．Just ignore it．

       C．Go to see a doctor．                           D．Ask your teachers for guidance．

2．“ It” in the last sentence of the second paragraph refers to ______．

       A．temporary loneliness                            B．situational loneliness

       C．a new place                                   D．sleeplessness

3．Why do psychologists want to help chronically lonely people ?

       A．Chronic loneliness can cause family problems．

       B．Chronic loneliness can cause serious illness．

       C．Chronic loneliness can not be overcome．

       D．Such people are harmful to society．

4．What is the best title for the passage?

       A．Three kinds of loneliness                 B．Loneliness and Diseases

       C．Loneliness and Social Contacts             D．Chronic Loneliness

7、Most musicians agree that the best violins were first made in Italy．They were made in Cremona, Italy, about 200 years ago．These violins sound better than any others．They even sound better than violins made today．Violin makers and scientists try to make instruments like the old Italian violins．But they aren’t the same．Musicians still prefer the old ones．No one really knows why these old Italian violins are so special, but many people think they have an answer．

Some people think it is the age of the violins．They say that today’s violins will also sound wonderful someday．But there is a problem here．Not all old violins sound wonderful．Only those from Cremona are special．So age cannot be the answer．There must be something different about Cremona or those Italian violin makers．

Other people think the secret to those violins is the wood．The wood of the violin is very important．It must be from certain kinds of trees．It must not be too young or too old．Perhaps the violin makers of Cremons knew something special about wood for violins．

But the kind of wood may not be so important．It may be more important to cut the wood in a special way．Wood for a violin must be cut very carefully．It has to be the right size and shape．The smallest difference will change the sound of the violin．Musicians sometimes think that this was the secret of the Italians．Maybe they understood more than we do about how to cut the wood．

Size and shape may not be the answer either．Scientists measured these old violins very carefully．They can make new ones that are exactly the same size and shape．But the new violins still do not sound as good as the old one．Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny．It also helps the sound of the instrument．No one knows what the Italian violin makers used in their varnish．So no one can make the same varnish today．

There may never be other violins like the violins of Cremona．Their secret may be lost forever．Young musicians today hope this is not true．They need fine violins．But there aren’t very many of the old violins left．Also, the old violins are very expensive．Recently, a famous old Italian violin was sold for about US $ 300,000!

6、When we can see well, we do not think about our eyes often．It is only when we can not see perfectly that we come to see how important our eyes are．

       People who are nearsighted can only see things that are very close to their eyes．Many people who do a lot of close work, such as writing and reading, become nearsighted．Then they have to wear glasses in order to see distant things clearly．

       People who are farsighted face just the opposite problem．They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length．If they want to do much reading, they must get glasses too．

       Other people do not see clearly because their eyes are not exactly the right shape．This, too, can be corrected by glasses．Some people’s eyes become cloudy because of cataracts．Long ago these people often became blind．Now, however, it is possible to operate on the cataracts and remove them．

       When night falls, colors become fainter to the eyes and finally disappear．After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers．Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction．This is because when you turn your head, you are looking at the thing too directly．Men on guard duty sometimes think they see something moving to one side of them．When they turn to look straight at it, they can not see it any more, and they believe they were mistaken．However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark．
