3．When a computer works on a group of programs，it can get very hot．Cooling the computer can cost a lot．So some scientists wonder what would happen if the heat from the computer could be used．
  Large Internet companies （公司） such as Google and Microsoft have thousands of computers．As these computers deal with information，they produce lots of heat，so they need huge cooling systems （系统）．These systems send the heat into the air．
   A company in Holland （荷兰） thinks paying to make the computers work and then p aying again to cool them are a waste of energy．So the company developed a special device-the e-Radiator．
   Boaz Leupe，head of the company，says that e-Radiator works as a heating system and saves money．He explains that the energy is used twice-once to heat the home and once to c ool the computer and that the users don't have to pay to cool their computers．
   Five homeowners in Holland are testing the heating system in their homes．
"We pay for the computer using，so，in that way，homeowners get heating for free，"Boaz says．
   Jan Visser is one of the homeowners．"If you use the computer more，the e-Radiator producers more heat，"he says，"It cannot provide enough heat if you don't use your computer often．"But he is ready to t ry it．It's a great help for his family．
  The company says e-Radiators produce heat temperatures of up to 55℃．It says the system could save its users about 440dollars a year．

9．Having a teenager at home can be a real headache．Many teenagers smoke，drink and even fight．They often do something dangerous．
Earlier studies have shown that teenagers are more likely （可能） to make irrational decisions than people from any other age group，including children and adults．Is it that teenagers are too young to tell right from wrong？Not really．So what's the reason？
According to Laurence，a teacher from a US university，the reason is that teenagers care a lot about how their peers （同龄人） view them-that is"peer influence"．
As children enter their teenage years，they spend more time with their friends and classmates，and also they care more about what they think of them．This makes teenagers make decisions without thinking about the costs．
In a test，a group of teenagers were asked to play a video driving game．When they played with their friends watching around them，they took more chances and drove more carelessly because that would increase their possibility of winning．But when they played alone，they drove more safely．
Why do peers have such a big influence on teens'behavior？
As Laurence sees it，a teenager's brain is like a car with a good accelerator （油门） but a weak brake （刹车）．The"accelerator"is fully developed by teenage years while the"brake"is still not fully developed．When teenagers are watched by their peers，they usually push hard on the accelerator．With their weak brake，it is likely that they are going to end up in an accident．
But the good news is that a violent （暴力的）teenager doesn't necessarily become a violent adult．About two-thirds to three-quarters of violent youth grow out of it．"They get more self-controlled．"

56．What does the underlined word"irrational"in the 2^nd paragraph mean？B
A．Quick．
B．Crazy．
C．Careful．
D．Correct．
57．Why are teenagers likely to make wrong decisions according to the text？D
A．They like difficult tasks．
B．They don't care about costs．
C．They are too young to tell right from wrong．
D．They care a lot about what their peers think of them．
58．How does Laurence explain the influence of peer pressure on teens'behavior？A
A．By comparing it with how a car works．
B．By comparing it with an accident．
C．By showing research findings．
D．By giving examples．
59．According to the text，with peers around them，teenagers are more likely toD．
A．use more self-control
B．perform better than when they are alone
C．become more careful about what they do
D．care about winning without thinking about danger
60．What can we conclude from the text？C
A．Teenagers are easy to have traffic accidents．
B．Peer influence is bad on teenagers．
C．Most of the teenagers become less violent when they grow up．
D．Teenagers shouldn't spend all the free time with their friends．

10．The rising costs of health care have become a problem for many countries in the world．To deal with this problem，it is reported that a big part of the government's health budge（预算）has been used for health education and disease prevention instead of treatment．Actually，many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it．For example，people could avoid catching a cold if they dressed warmly when the weather starts getting cold．But many people get sick because they fail to do so，and have to spend money seeing a doctor．
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt（破产）if the patients had taken ways for early prevention．For example，keeping a balanced diet（均衡饮食），such as not consuming too much animal fat and trying to have enough vegetables and fruits，seems to be quite important．
One very effective and costless way of prevention is regular（定期的）exercise，which is necessary for a healthy mind and body．Regular exercise，such as running，walking，and playing sports is a good way to make people feel better．
In addition，health education plays a key role in improving people's health．By giving people more information about health，countries could help people understand the importance of disease prevention and ways to achieve it．For example，knowing one's family medical history is an effective way to help keep healthy．Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes，which will work before it is too late．However，paying more attention to disease prevention does not mean medical treatment is unimportant．After all，prevention and treatment are just two different means toward the same effect．In conclusion，we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education．
