7.It is said that 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 our brains are not getting enough exercise-and as a result,we are growing old 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 varying occupations.Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side parts of the brain,which controls functions like eating and breathing,does not contract with age,and one can continue living without intellectual on economical faculties.Contraction of front and side parts-as cells die off-was observed in some subjects in their thirties,but it was still not evident in some sixty-and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple way to the contraction normally connected 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 the town.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 the farm worker,bus driver and shop assistant.
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 maintain,good blood circulation is through using the brain."he says."Think hard and engage in conversation.Don't rely on pocket calculators."

A.Lawyers.B.Farmers.C.Clerks.D.Shop assistants.
分析 想要保持年轻吗?单从头脑上来说,越是乐于思考、使用大脑的人,越不容易脑衰老,日本学者的研究如是表示.律师这样的职业,衰老的速度要小于别的行业.
解答 8.D.细节理解题.由第二段"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 ageing could be slowed down."可知医生们想要研究出为什么一些人比其他人老得更快.故选D.
9.A.细节理解题.由"he set about measuring brain volumes of a thousand people of different ages and varying occupations."他着手测量不同年龄和不同职业的人的脑容量,可知选A.
10.D.理解推断题题.由第三段Matsuzawa concluded from his tests that there is a simple way to the contraction normally connected with age-using the head,.Those least at risk,says Matsuzawa,are lawyers,followed by university professors and doctors,可知大脑的收缩和住在城市乡村有关,也和职业有关,因此有的人脑收缩比其他人更多.故选D.
11.A.细节理解题.由"Those least at risk,says Matsuzawa,are lawyers"可知律师变老的风险最小.故选A.
点评 科教类阅读难度比一般阅读较大,它存在的生词比较多,因此考生应当综合略读、跳读和查读,猜词等阅读技巧来做题,平时也应加强练习.
