Many psychologists in the early twentieth century believed that humans use only 10 percent of their brains, and even the great Albert Einstein once wrote that most people use only a small portion of the grey matter between their ears. It's a theory that has often been put forward in television documentaries; magazines, advertisements and books over the past century.

       But nearly all scientists now agree the 10 percent theory is completely unfounded. In fact, they question how this figure was ever arrived at in the first place and what areas of the brain are supposed to be unneeded. The theory supposes that if 90 percent of the brain were removed, a person would Still be able to function normally, while in reality it is known that damage to even a small area of the brain can result in extremely serious physical injury different activities and that many areas of the brain are used at the same time for some complex activities or thought processes.

       Throughout the course of one day, most .areas of the brain are active at some time, even during sleep. The 10 percent theory suggests that certain areas o' the brain are not used, but scans slow activities throughout the entire brain and not in any separate part. The final argument against the 10 percent theory is the fact that doctors carefully map the brain before removing brain cancers so that they don't affect other essential areas.

       From an evolutionary point of view, it's highly unlikely butt our comparatively larger brains would have evolved from our ancestors if the extra areas were not needed. In fact, there is absolutely no evidence support the 10 percent theory.

   B. Most brain disorders affect the same part of the brain.

   C. The brain is less active during times of sleep.

A round of applause, please, for the Indian man who recently sang for 80 hours straight, setting a new Guinness world record. It’s an impressive feat, to be sure, but let’s just hope he still has a voice．According to Indian newspapers, Rajesh Burbure has been told to keep silent for several days so his vocal cords can heal.

It was reported that Burbure and his family are in a celebratory mood. “It’s a proud moment for all of us,” his wife told DNAIndia.com.

I, on the other hand, am unable to share their enthusiasm. Don’t get me wrong: I hope the 35-year-old Burbure lives forever, sells a million records and becomes an international celebrity. But his record—singing for 80 hours straight—is about as meaningful as most of the other curious but crazy feats listed in the Guinness Book of World Records.

Granted, I’m not qualified to speak on the subject. I’ve got no world records to my name, and I never expect to have any. Then again, maybe I am qualified to speak for those of us who have better things to do than train for years to sing an 80-hour medley of pop songs.

But let’s not just blame poor Burbure. He’s not the only person chasing meaningless reputation．The Guinness Book of World Records is full of the names of people who at one time grew the longest hair, or built the biggest bicycle, or baked the largest cheesecake.

To all of these enterprising souls I ask, simply, “What was it all for?”

Congratulations! For all of your painstaking effort, you became a footnote in a thick book that no one reads, except for you and the person who will eventually surpass you, with one more hour of singing, a few more centimeters of steel or a few more pounds of cheese.

After all, records are made to be broken.

60. From the text, we can conclude that the author _________.

       A. thinks singing for 80 hours straight is completely meaningless

       B. feels it a pity he was not invited to share the happiness with the Burbures

       C. is quite worried about Burbure’s vocal cords

       D. has no Guinness records, so he admires Burbures’ feat

61. The author’s attitude to some Guinness world records is ________.

       A. positive                   B. impressed                       C. negative                          D. touched

62. We can infer from the article that ________.

       A. after the 80 hours of singing, Burbure could no longer speak

       B. Burbure’s wife didn’t support his attempt to make a Guinness record

       C. many have criticized Burbure for his stupid behavior

       D. challenging a Guinness record may be harmful to the health

63. What can possibly be the best title for the passage?

       A. What Was the Point                                             B. The Boring Guinness Book

       C. A New Guinness Record                                      D. Records Are Made to be Broken

Someday a stranger will read your e-mail without your permission or scan the websites you’ve visited. Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.

    In fact，it’s likely some of these things have already happened to you．Who would watch you without your permission? It might be a girlfriend，a marketing company, a boss，a policeman or a criminal. Whoever it is，they will see you in a way you never intended to be seen — the 21^st century equal to being caught naked (裸露的).

    Psychologists tell us boundaries are healthy, though it's important to reveal (透露) yourself to friends，family and lovers in stages, at appropriate times. Actually few boundaries remain. The digital breadcrumbs (面包屑) you leave everywhere make it easy for strangers to reconstruct who you are，where you are and what you like. In some cases，a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.

    The key question is: Does that matter? For many Americans, the answer apparently is “no”.

    When opinion polls (民意调查) ask Americans about privacy, most say they are concerned about losing it. A survey found a majority of people are pessimistic (悲观的) about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me.”

    But people say one thing and do another. Only a small part of Americans change any behaviors in an effort to protect their privacy. Few people turn down a discount at tollbooths (收费亭) to avoid using the EZ — Pass system that can track (跟踪) automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquits has run a series of tests that reveal people will submit personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon (优惠券).

But privacy does matter — at least sometimes. It’s like health; when you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it.

Computer people talk a lot about the need for other people to become"computer-literate."But not all experts (专家) agree that this is a good idea.One ploneer,in particular,who disagrees is David Tebbutt,the founder of ComputertownUK. Although many people see this as a successful attempt to bring people closer to the computer.David does not see it that way.He says that Computertown UK was formed for just the opposite reason,to bring computers to people and make them"people-literate."David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two,The clubs are for people who have some computer knowledge already.This frightens away non-experts,who are happier going to Computertowns where there are computers for them to experiment on.with experts to encourage them and answer any questions they have,They are not told what to do.they find out.The computer experts have to learn not to tell people about computers.but have to be able to answer all questions people ask.People don't have to learn computer terms(术语), but the experts have to expla in plain language. The computers are becoming "peoPle-literate."

Why do some people have many friends while others do not? __1__ However, it is not so. Let's look at two psychological experiments which will give you the key to happy interpersonal relations.

The first experiment is called the “Hawthorne effect” after Hawthorne, Illinois, where the experiment took place. A group of psychologists examined the work patterns of two groups of workers in the Western Electric Company.__2__The psychologists changed the working conditions for one group twice but left the other group alone. They were surprised to find that productivity increase on both occasions and in both groups.

They concluded that the increase in productivity came from the attention given to the workers by the management. It had increased their motivation (积极性) and so they had worked harder. In other words, if you take an interest in others ，they will want to please you and you will have good relations with them.

　 __3__ After Martin Luther King, Jr was killed in the 1960s, a teacher, Jane Elliott, living in an all – white town decided to help her class of young children understand why the Civil Rights Movement had been necessary in America.

　 She divided the class into two groups: one with blue eyes and the other with brown eyes. Other eye colours such as hazel or green were excluded from his exercise. Then she told the class that brown－eyed people were cleverer than blue－eyed ones because of an agent (化学作用) for brown colour found in their blood. Blue－eyed people were stupid, lazy and not to be trusted. Jane Elliott did not need to say any more.

　 The brown－eyed students quickly got used to their new role as the leaders of the class. The blue－eyed students became quiet and withdrawn. Then she discovered something very interesting. Four poor brown－eyed readers began to read fluently in a way they had never done before. __4__ So if you want to be successful and happy, take an interest in others whether they are your classmates or workmates. Congratulate them on their successes and sympathise(同情) with them in their troubles. __5__

A. Before the experiment the management talked to both groups of workers and explained that they wanted to find the best working environment for them.

B. Remember that the way you treat others will decide their attitude and behaviour to you.

C. The second experiment shows what happens to personal relations if you are rude to or ignore(忽略) others.

D. The ones who have more friends usually are those who care about others.

E. Jane Elliott had shown that the way people are treated affects not only their behaviour but also their confidence and their performance.

F．You may even imagine that this ability was something they were born with because it seems so effortless to them.

G. The second experiment tells us what teachers said has a great effect on the students.
