1.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一and as a result,we are ageing unnecessarily soon.
2.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.
3.With a team of colleagues at Tokyo National University,he set about measuring brain yolumes of a thousand people of different ages and varying occupations.
4.Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect（智能）and emotion, and determine the human character. The rear section of the brain,which controls functions like eating and breathing,does not contract with age,and one can continue living without intellectual or emotional faculties.
5.Contraction of front and side parts一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.
6.Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age一using the head.
7.The findings show in general terms that contraction of the brain begins sooner in people in the country than in the 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 brains as the farm worker,bus driver and shop assistant.
8.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."

The front and side sections of the brain relates to_________.
A:blood circulation
B:slowed down
C:occupation
D:intellect and emotion
E:eating and breathing
F: fresh oxygen

答案：D
解析：

第四段中提到："Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain...（运用电脑技术可以精确测量出头的前部和侧面大脑的容积·······）"，因此选择F。
第七段说的是，在城市里生活的人和在农村生活的人的大脑开始衰老的时间是不同的。因此选择E。
第八段第一句："Matsuzawa's findings show that thinking can prevent the brain from shrinking.（思考可以防止大脑姜缩）”。随后的内容也是对该主题句的进一步解释，因此选择A。

Sleep Lets Brain File Memories

To sleep.Perchance to file?Findings published online this week by the proceedings of the National Academy of Sciences further support the theory that the brain organizes and stows memories formed during the day while the rest of the body is catching zzz's.
Gyorgy Buzsaki of Rutgers University and his colleagues analyzed the brain waves of sleeping rats and mice. Specifically,they examined the electrical activity emanating（散发）from the somatosensory（耳、目、口等以外的）neocortex（新大脑皮层）(an area that processes sensory information) and the hippocampus（海马）,which is a center for learning and memory. The scientists found that oscillations in brain waves from the two regions appear to be intertwined.So-called sleep spindles (bursts of activity from the neocortex)were followed tens of milliseconds later by beats in the hippocampus known as ripples.The team posits that this interplay between the two brain regions is a key step in memory consolidation.
A second study,also published online this week by the proceedings of the National Academy of Sciences,links age-associated memory decline to high glucose levels.
Previous research had shown that individuals with diabetes（糖尿病，多尿症）suffer from increased memory problems.In the new work,Antonio Convit of New York University School of Medicine and his collaborators studied 30 people whose average age was 69 to investigate whether sugar levels,which tend to increase with age,affect memory in healthy people as well.The scientists administered recall tests, brain scans（细看，审视，浏览，扫描）and glucose tolerance tests, which measure how quickly sugar is absorbed from the blood by the body's tissues.Subjects with the poorest memory recollection,the team discovered,also displayed the poorest glucose tolerance.In addition,their brain scans showed more hippocampus shrinkage than those of subjects better able to absorb blood sugar.
" Our study suggests that this impairment（损害、损伤）may contribute to the memory deficits （赤字、不足额）that occur as people age."Convit says."And it raises the intriguing possibility that improving glucose tolerance could reverse some age-associated problems in cognition."Exercise and weight control can help keep glucose levels in check（阻止、制止）,so there may be one more reason to go to the gym.

Which of the following statements is nearest in meaning to the sentence"To sleep.Perchance to file?"
A:Does brain arrange memories in useful order during sleep?
B:Does brain have memories when one is sleeping?
C:Does brain remember files after one falls asleep?
D:Does brain work on files in sleep?

答案：A
解析：
To sleep.Perchance to file？ 即当人体进入睡眠状态时，大脑对在白天形成的记忆进行组织和储存。
第二段告诉我们，科学家分析了老鼠的脑电波，尤其是从somatosensory neocortex和hippocampus两个区域发出的脑电波。该段最后两句指出，这两个大脑区域的活动是互相作用的。第二段并没有说somatosensory neocortex或hippocampus起主导作用。
第四段倒数第二句提供了答案。
第四段最后一句中their brain scans，指上句中的subjects with the poorest memory recollection的大脑扫描，所以选择B项。
锻炼身体和控制体重能保持葡萄糖水平，因此，去健身房就有了另外一个理由。
