Who are these people rushing by you on the street? More than 250 million people now call Amer??ica" home" , but most of them can trace their families back to other parts of the world. If you, look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States,have lost the customs and cultures of their original countries and have become "Americans"is really not true. In fact, what exists in Ameri??ca is - more often a kind of “ side - by - side" living in which groups of people from other countries often have kept many of their own customs and habits. They join the general American society only in certain areas of their lives such as in schools,business,and sports一but they keep many of their own native customs and manners socially and at home. This “ side - by - side" living has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas ’ dress, food, and social customs in America. Everyone can find some part of his or her own familiar world in the United States, in churches, music, food, national groups, or newspaper.

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of out brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain sizes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the sizes of the front and side parts of the brain, which have something to do with thinking and feeling, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract(萎缩) with age.
Contraction of front and side parts, as cells(细胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.
The findings show that contraction of the brain begins sooner in people in the country than those in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White-collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm workers, bus drivers and shop assistants.
【小题1】 The team of doctors wanted to find out ____.

A.at what point people grow live longer.
B.how to make people live longer
C.the size of certain people’s brains.
D.which group of people are the busiest
【小题2】Their research findings are based on ______.c
A.an examination of farmers in northern Japan
B.using computer technology
C.examining the brain sizes of different people
D.tests given a thousand old people
【小题3】The doctor’s tests show that ______.
A.our brains contract as we grow older
B.one part of the brain does not contract
C.sixty-year-olds have better brains than thirty-year-olds
D.contraction of the brain begins sooner in people in the country
【小题4】 According to the article, _____ are growing mentally old earlier.
A.engineersB.office clerksC.professorsD.researchers
【小题5】The most possible conclusion of the article is that ____.
A.most of us should take more exercise
B.it’s better to live in the towns
C.the brain contracts if it is not used
D.the more one uses his brain, the sooner he becomes old

阅读下面短文并回答问题, (请注意问题后的词数要求)。

[1]One person can make a difference. Just ask Ryan Hreljac, who is 15 and lives in Canada. Without his help, hundreds of wells that now provide fresh water for people in Africa, Central America, and India might never have been built. He travels the world to tell people how they can help solve a big problem: _______ in many developing countries.

[2] In 1998, when he was 6 years old, Ryan learned that children in Africa often must walk miles each day to find water. Some even die from drinking bad water in some developing countries, his teacher says. So Ryan decided to act. He spoke to schools, churches, and clubs about his goal. The word spread, and donations began coming in. After several months of hard work, Ryan had raised $2,000, enough to dig one well. An organization called Canadian Physicians for Aid and Relief chose a location for the well in the village of Agweo in Africa.

[3] After the first well, “the ripple effect took over,” Ryan says, “and one goal led to another.” Its website (www.ryanswell.ca) lists some of the famous people Ryan has met and the awards he has received. “The most impressive people I’ve met are the other kids who want to help, too,” he says. “The only reason I accept awards is that each word I say when I get one might help one more person.”

[4] Asked if he ever feels discouraged that many people still lack good water, Ryan says, “It’s important to be an optimist. I had a small dream, and I stayed with it. Everybody can do something.”

1. What’s the main idea of Paragraph 2? (no more 10 words)

_______________________________________________________________________

2. Explain the underlined sentence in Paragraph3 in English.

_______________________________________________________________________

3. For what purpose does Ryan accept awards? (no more 15 words)

4. According to what Ryan said in Paragraph4, what is Ryan’s attitude toward his work? (no more 6 words)
