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(萎縮) with age.
Contraction of front and side parts, as cells(細胞) 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.
【小題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
【小題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
【小題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
【小題4】 According to the article, _____ are growing mentally old earlier.
A.engineersB.office clerksC.professorsD.researchers
【小題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

閱讀理解

  Chess-playing machines were a common feature at the 19th century carnivals(狂歡節) .They would take on all competitors and usually wan, but they were all frauds(騙局)with human beings concealed inside.

  Two centuries later, the “machine” is real.

  A computer programmer Deep Fritz held world champion, Vladimir Kramnik, to a 4-4 tie. In doing so, Kramnik felt just short of avenging (復仇)the 1997 defeat of his predecessor Garry Kasparov at the hands of IBM's Deep Blue.

  Deep Fritz is a commercially available product produced by Germany's Chessbase Gmbh. In this match it was running on 8,900 Mhz processors and could analyze 3 million positions a second.

  Kramnk admitted he found the match exhausting. “ I need some time to recover. ”he said comparing the match with his 2000 defeat of Kasparov. “The pressure is similar but preparing against a computer is much more difficult. It has all the knowledge and you have to be prepared for all openings. With a human, you know that certain openings don't suit his style and won't happen, but not with a computer. ”

  “The games themselves were different,” he said, “Against a computer, you have a feeling that if you make one mistake, it's over. So it's like going through a minefield. You're always watching for tactics, even in a quiet position.”

  He also said that computers play faster. “The game has a different rhythm and it puts more pressure on you.”

  “The main problem, ”he said, “is that you can never understand its logic. In a human sense, it has no logic. With a human opponent, you feel him and you know what path he will take.”

  Chess enthusiasts have been arguing for centuries whether it's an art, a science, a sport or something else.

  Kramnik doesn't see the emergence of computers making any difference to this argument. “Chess is very wide. It's not merely these things but a small model of the world. ”

  Next spring, Kramnik is scheduled to defend his title as Einstein Classical Chess World Champion against Peter Leko of Hungary. While he welcomes a rematch against Fritz, it's not certain when it will take place.

1.The difficulties of competing with the computer doesn't lie in that ________.

[  ]

A.you can never understand its logic

B.the computer plays faster

C.it has all knowledge and you have to prepare for all openings

D.if you make one mistake, it's over

2.The underlined word “exhausing” ( in Para. 5 ) means ________.

[  ]

A.making something interesting

B.making someone excited

C.making someone tired

D.making something endless

3.Put the following events in the right order:

(1) Garry Kasparov was defeated by Deep Blue .

(2)Chess-playing machines were not real.

( 3 ) After competing with Deep Fritz, Kramnik felt exhausted .

(4)Kramnik's competition with Peter Leko of Hungary.

[  ]

A.(2)-(4)-(1)-(3)

B.(2)-(1)-(3)-(4)

C.(2)-(3)-(4)-(1)

D.(1)-(A)-(3)-(2)

4.What did Kramnik think of the chess?

[  ]

A.It became more and more difficult after the chess-playing machines were invented.

B.Chess is an art, a science, a sport, etc.

C.It's more and more popular, with the computer developing.

D.Chess is a small world which is wide.
