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.

   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

4. According to the article, _____ are growing mentally old earlier.

   A. engineers    B. office clerks    C. professors    D. researchers

5.The most possible conclusion of the article is that ____.

 There is a story of a country where the rate of inflation(通货膨胀率)is so high that clever people pay for a taxi ride before the trip instead of after. This story may or may not be true. But inflation was almost that serious in Germany from July 1920 until December 1923. Prices went up so fast that by the end of 1923 they were 50 billion percent higher-a rise of almost 25000 / 40 a month.

  There was so much paper money, and it had so little value, that people carried bags full of money around to pay for things. One woman told the story of standing outside a shop with a basket full of 500 000 mark notes(马克). She wanted to buy just one piece of meat, and she hoped she had enough money. But when she was looking, a thief robbed(抢夺) her. He didn't take her money, though, he threw it away and took the basket in stead.

  At first workers demanded to be paid every day. But as the situation be came worse, they had to be paid twice a day. But they had to run out and spend the money at once, or it would lose its value. People bought anything that was for sale, but food was almost impossible to find. Farm workers re fused to take money. They wanted to be paid in potatoes instead.

  New policies(政策)ended the inflation in 1923, when the government introduced a new money. But about half of the German people lost every thing in those three and a half years.

  1.People paid for a taxi ride before the trip because they________

    A. did not want to carry so much money with them

    B. had so much paper money that they wanted to spend them quickly

    A. higher than those in 1923

    B. lower than those in 1923

    C. the highest in history

    D. the lowest in history

  

  3.The thief stole the basket instead of the money in it because he thought _________

    A. he couldn't buy a piece of meat with the money

    B. the basket was more valuable than the money

    C. the basket was what he needed most

    D. the money was of no value

If you want to stay young, sit down and have agood think. This is the research finding of a team of Japanese doctors who say that most of our brains are not getting enough exercise and as a result, we are aging unnecessarily soon.

    Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the

process of aging could be slowed down.With a team of colleagues at Tokyo National University,

he set about measuring brain volumes of a thousand people of different ages and jobs.

Computer technology enabled the researchers to get right measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. Contraction (收缩) of the front and side parts as cells died was observed in some subjects in their thirties, but it was still not clear in some sixty and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy (补救) to the contraction normally associated with age using the head.

    The findings show in general terms that contraction of the brain begins sooner in people in the country than in towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as farm workers, bus drivers and shop assistants.

    Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."w

The team of doctors wanted to find out ______.

A. why certain people age sooner than others   B. how to make people live much longer

C. the size of certain people's brains          D. the people with more intelligence

On what are their research findings based?

A. A survey of farmers in northern Japan.

B. Tests performed on a thousand old people.

C. The study of brain volumes of different people.

D. The latest development of computer technology.

Matsuzawa thinks that _______.

A. our brains grow as we grow older

B. the front section of the brain does not shrink

C. sixty-year-old people have better brains than thirty-year-olds

D. the contraction of brains is connected with brain exercise

According to the passage, which people seem to age slower than others?

A. Farmers.     B. Lawyers.     C. Government workers.     D. Shop assistants.w
