6.Ever walked to the shops only to find once there you've completely forgotten what you went for?Orstruggled to remember the name of an old acquaintance?For years we've accepted that a scatty(低能的)brain is as much a part of aging as wrinkles(皱纹)and grey hair.But now a new book suggests that
we've got it wrong.
According to the Secret Life of the Grown-up Brain,by science writer Barbara Strauch,when it comes
to the important stuff,our brains actually get better with age.In fact,she argues that new studies
have found that our brain hits its peak between our 40s and 60s---much later than previously thought.
Furthermore,rather than losing many brain cells as we age,we retain them,and even produce new ones well into middle age.For years it's been assumed that brain,much like the body,declines with age.
But the longest,largest study into what happens to people as they age suggests otherwise.
This continuing research has followed 6,000 people since 1956,testing them every seven years.It
has found that,on average,participants performed better on cognitive (认知的)tests in their late 40s
and 50s than they had in their 20s.Specifically,older people did better on tests of vocabulary,spatial orientation (空间定向)skills,verbal memory and problem solving.
Where they did less well was number ability and perceptual (感性的)speed---how fast you can
push a button when prompted (提示).However,with more complex tasks such as problem-solving and
language,we are at our best at middle age and beyond.In short,researchers are now coming up with
scientific proof of that we do get wiser with age.
Neuroscientists are also finding that we are happier with age.Older people were much better at
controlling and balancing their emotions.It is thought that when we're younger we need to focus more
on the negative aspects of life in order to learn about the possible dangers in the world,but as we get
older we've learnt our lessons and are sub-consciously aware that we have less time left in life-and it
therefore becomes more important for us to be happy.

分析 短文主要通过推翻"以往人们认为随着年龄的增长,我们脑袋越不好用"这个理念,通过科学研究表明:人越老越聪明.
解答 46.A,推理判断题,短文开头通过两个问题是为了引出其主题,以前我们觉得随着年龄的增长,我们脑袋越不好用,但短文通过研究表明:人越老越聪明,故答案为A.
47.B,细节理解题,根据句子For years we've accepted that a scatty(低能的)brain is as much a part of aging as wrinkles(皱纹)and grey hair.可知,以前人们认为随着年龄的增长我们的脑袋越不好用,故答案为B.
48.C,细节理解题,根据句子Where they did less well was number ability and perceptual (感性的)speed---how fast you can push a button when prompted (提示).可知,年长者在感性速度方面不太好,也就是身体反应速度,故答案为C.
49.D,细节理解题,根据句子but as we get older we've learnt our lessons and are sub-consciously aware that we have less time left in life-and it therefore becomes more important for us to be happy.可知,年长者意识到自己剩下的时间不多,故而快乐对于他们来说才是重要的,故答案为D.
50.A,标题归纳题,短文主要通过推翻"以往人们认为随着年龄的增长,我们脑袋越不好用"这个理念,通过科学研究表明:人越老越聪明,故最好的题目为A.
