       Our brains work in complex and strange ways.There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two.Others can perform complex classical piano pieces after hearing them once, but they cannot read or write.

       Dr.J.Langdon Down first described this condition in 1887.He called these people idiot savants.An idiot savant is a person who has significant mental impairment (损伤) , such as in autism ( 孤独症,自闭症) or retardation.At the same time, the person also exhibits some extraordinary skills, which are unusual for most people.The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory.

       One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr.Benjamin Rush, an American doctor.His patient, Thomas Fuller, was brought to Virginia as a slave in1724.It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds.Despite this ability, he died in 1790 without ever learning to read or write.

       Another idiot savant slave became famous as a pianist in the 1860s.Blind Tom had a vocabulary of only 100 words, but he played 5 ,000 musical pieces beautifully.

       In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly.

       Today we more clearly recognize that the idiot savant is special because of brain impairment.Yet not all brain impairment leads to savant skills.Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills.However few people wish to participate in such experiments.There are many excellent reasons for not undergoing unnecessary experimentation on one's brain.The term idiot savant is outdated and inappropriate.Virtually all savants have a high degree of intelligence and are thus not idiots.

What does the passage mainly talk about?

       A.Idiot savants have areas of outstanding abilities.

       B.Human Beings have complicated thinking process.

       C.The brains of the idiot savants are partly impaired.

       D.The reasons why people have wonderful skills vary.

Which of the following can be done by Rain Man?

       A.He can play wonderful pieces of classical music.

       B.He can guess out exactly the length of a man's life.

       C.He can memorize the contents of the pictures fast.

       D.He can count matches dropped on the floor quickly.

What can you infer from the passage?

       A.Idiot savants have real talents for art and math.

       B.Dr.Down is the first person who found idiot savants.

       C.Few people wish to risk becoming savants by brain operations.

       D.Intentional left brain impairments will surely lead to idiot savants.

Which of the following shows the structure of the passage?

Too many people want others to be their friends, but they don't give friendship back. That is why some friendships don't last very long. To have a friend, you must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

Honesty is where a good friendship starts. Friends must be able to trust one another. If you don't tell the truth, people usually find out. If a friend finds out that you haven't been honest, you may lose your friend's trust. Good friends always count on one another to speak and act honestly.

Generosity(大度) means sharing and sharing makes a friendship grow. You don't have to give your lunch money or your clothes, of course. Instead you have to learn how to share things you enjoy, like your hobbies and your interests. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them you help your friend know you better.

Sooner or later everyone needs understanding and help with a problem. Something may go wrong at school. Talking about the problem can make it easier to solve(解决). Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend's place so you can understand the problem better.

      For as long as I can remember, I have been very bad at arguing with people. As soon as someone disagrees with me, I get angry because I feel attacked, like the other person is out to show that I am wrong. And for some reason, I hate being wrong! So my immediate reaction is to get very defensive, I raise my voice, and I end up saying something I later regret. Needless to say, the whole thing ends with me beating myself up, and the other person feeling alienated (疏远) from me. This bothers me especially because my mother does the exact same thing and I hate it!
I have noticed this tendency in me for a long time now, but I have never been able to stop. I did some anger management work with a therapist (治疗专家) a while ago, but because I moved and turned to an advisor at school who cannot see me regularly, I have not been able to continue this important work. They tell you to stop and count to 10, control your breathing, calm yourself down before you talk. But that's the whole problem, I could never think of stopping myself until it was too late! The hurtful things had already come out of my mouth, and I was stuck picking up the pieces.
Right now the problem is urgent because my relationship with a wonderful boyfriend is in danger because of my insecurity and hatred of being wrong. He is closing himself off to me because I have hurt him, and no doubt I am no longer attractive as a woman with no confidence in herself and a bad temper. How do I stop ruining my relationships and hating myself? How do I stop hating being wrong?

Until the 1980s, the American homeless population is mainly made up of older males. Today, homelessness strikes much younger part of society. In fact, a 25-city survey by the U. S. Conference of Mayors in 1987 found that families with children make up the fastest growing part of the homeless population. Many homeless children gather in inner cities; this transient(变化无常的) and frequently frightened student population creates additional problems — both legal and educational — for already overburdened urban school administrators and teachers.
Estimates of the number of homeless Americans range from 350,000 to three million. Likewise, estimates of the number of homeless school children vary radically. A U.S. Department of Education report, based on state estimates, states that there are 220,000 homeless school-age children, about a third of whom do not attend school on a regular basis. But the National Coalition for the Homeless estimates that there are at least two times as many homeless children, and that less than half of them attend school regularly.
One part of the homeless population that is particularly difficult to count consists of the “throwaway” youths who have been cast of their homes. The Elementary School Center in New York City estimates that there are 1.5 million of them, many of whom are not treated as children because they do not stay in family shelters and tend to live by themselves on the streets.
Federal law, the Stewart B. McKinney Homeless Assistance Act of 1987, includes a section that addresses the educational needs of homeless children. The educational provisions(规定) of the McKinney Act are based on the belief that all homeless children have the right to a free, appropriate education.
1.It is implied in the first paragraph that ____.

Athe writer himself is homeless, even in his eighties

Bmany older homeless residents are going on strike in 25 cities

Cthere is a serious shortage of academic facilities

Dhomeless children are denied the opportunity of receiving free education

2.The National Coalition for the homeless believes that the number of homeless children is _____.

A350,000? B1,500,000? C440,000? D110,000

3.One part of the homeless population is difficult to estimate. The reason might well be ____.

Athe homeless children are too young to be treated as children

Bthe homeless population is growing rapidly

Cthe homeless children usually stay outside school

Dsome homeless children are deserted by their families

4.The McKinney Act is mentioned in this passage in order to show that ___.

Athe educational problems of homeless children are being recognized

Bthe estimates on homeless children are hard to determine

Cthe address of grade-school children should be located

Dall homeless people should have free education

In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by all environmental protection organization, which has contributed to improving the living environment for wild animals. Recently, the organization has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment.

In the area, the local people have planted many special flowers with the help of the organization, aiming to see whether these flowers will interest the rare and beautiful butterflies. The project officer Sarah Marshall says,“It will be a suitable habitat (栖息地) for butterflies. They are great‘indicator species’ as they are easily affected by climate changes so they make a brilliant early-warning system for the environment.” She also points out that volunteers are needed to record the number or species of butterflies, and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.

The organization is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way. Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. “Staff will provide back up, so if the weather is poor on the day you are to visit (butterflies don’t like to fly in the rain, wind or if it’s too cloudy) we can have someone else do your job,” Sarah points out.

No previous experience is necessary as training and support will be provided, but a keen interest is essential. If you are interested please contact Sarah on (01380) 725670, ext 278, email—sarahm @ wiltshirewildlife. org.
