Ⅲ.阅读理解
第一节
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
A
The Internet brings us many advantages.
With the Internet, people can send and receive e mails.On the Internet, people can skim over news.Using the Telnet, the user anywhere on the Internet can log into any other machine on which he has an account.It is possible to use the FTP program to copy files from one machine on the Internet to another.
But the Internet also brings us troubles.
Internet use seems to cause a fall in psychological(心理的) health, according to research at Carnegie Mellon University.Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less often, the two year study showed.And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually seemed to cause the bad feelings.[来源:www.shulihua.net数理化网]
Researchers are puzzling over the results, which were completely opposite to what they had expected.They expected that the Net would prove socially healthier than the television, since the Net allows users to choose their information and to communicate with others.
The fact that Internet use reduces time used for family and friends may be the reason for the drop in health, researchers said.Faceless, bodiless“virtual”(虚拟的) communication may be less psychologically satisfying than actual conversations, and the relationships formed through it may not be so deep.Another possibility is that exposure to the wider world through the Net makes users less satisfied with their lives.
“But it's important to remember this is not about the technology; it's about how it is used，” said one of the researchers.“It really points to the need for considering social factors(因素) when you design new inventions.”
36．The writer mainly wants to tell us that ______.
A．the Internet can bring people many advantages
B．the Internet use may cause psychological problems
C．the Internet users are not satisfied with their lives
D．we shouldn't use the Internet
37．Why are the researchers puzzling over the results?
A．Because the results were completely different from what they had thought.
B．Because the Net proved socially healthier than the television.
C．Because the Internet users were all healthier.
D．Because the Internet users experienced less depression and loneliness.
38．What may be the reasons why Internet use causes a fall in psychological health?
A．Internet use reduces time used for family and friends.
B．Virtual communication is less psychologically satisfying than actual conversations.
C．Exposure to the wider world through the Net makes users less satisfied with their lives.
D．All the above.
39．What does the underlined part in the last paragraph mean?
A．What matters is not the technology but how it is used.[来源:www.shulihua.net]
B．This passage is not about the technology but about how it is used.
C．We should remember to learn about the technology.
D．We should remember to learn how to use computers.
B
Computer technology is still developing rapidly.The computer of the future will continue to increase in value and performance while decreasing in cost.It will become smaller，but faster and more powerful.
It is possible to make some guesses about what the future of the computer will look like，based upon the types of technologies that are being developed now.A lot of progress has already been made in some of these new technologies，but some are still in their earliest stages and may not be ready for use for years.Two of the most interesting areas of computing that are currently being developed are quantum computing(量子计算) and nanotechnology(纳米技术)．
Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today.Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.[来源:www.shulihua.net]
Nanotechnology could also change the face of computing，by creating computers that could be very powerful，though they are tiny in size.These computers could be incorporated(并入) into everyday objects，including electrical appliances(电器)，clothes and even the human body.We will be able to use computers in new and unimaginable ways.They will become a part of our lives rather than simply being a box that is used only for specific purposes，such as work.
Quantum computing and nanotechnology will be able to play new roles，which will make us live greener lives，as well as enjoy healthier and happier lives.
40．Which of the following can NOT describe the computer of the future properly?
A．Much smaller. B．Much faster.
C．More powerful. D．Less valuable.
41．According to the text，quantum computing ______.
A．has been put in use so far
B．can make computers run by themselves
C．can reduce the cost of computers
D．will work by using transistors
42．We can learn from the text that nanotechnology will ______.
A．create much smaller computers
B．be used in electrical appliances and clothing
C．change the structure of computers
D．make computers just serve specific purposes
43．The text is mainly about ______.
A．what nanotechnology is
B．what quantum computing is
C．what the future of the computer is
D．what future computers can bring us
第二节
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
There is an English saying：__44__ Until recently，few people took the saying seriously.Now，however，doctors have begun to look into laughter and the effects it has on the human body.__45__
Tests were carried out to study the effects of laughter on the body.People watched funny films while doctors checked their hearts，blood pressure，breathing and muscles.It was found that laughter has similar effects to physical exercise.__46__ If laughter exercises the body，it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body.In one experiment doctors produced pain in groups of students who listened to different radio programs.The group that tolerated(忍耐) the pain for the longest time was the group which listened to a funny program.__47__
__48__ They have found that even if their patients do not really feel like laughing，making them smile is enough to produce beneficial effects similar to those caused by laughter.
A．Laughter can prolong one's life.
B．As a result of these discoveries，some doctors in the United States now hold laughter clinics in which they help to improve their patients' condition by encouraging them to laugh.
C．The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminish both stress and pain.
D．It increases blood pressure，the heart beating and breathing；it also works several groups of muscles in the face，the stomach and even the feet.
E．Although laughter helps cure the disease，doctors still can not put this theory into clinic practice.
F．Laughter is the best medicine.
G．They have found that laughter really can improve people's health.

My parents are both interested in reading and music，but my father prefers to history books while my mother likes to read novel and magazines.As for music，their tastes are similarly，and they had never been tired of folk music.Most of the time，they are in agreement about bring up children.They both believe in giving their children a love and none believes in punishing a child physically.At times，their characters are very much alike，but at others times，they seem differently.
Perhaps that is why none of their children knows for sure which parents he takes after.
