Question

【題目】Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we’ve got it all wrong.

According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some 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 keep 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 (認(rèn)知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed — how fast you can push a button when ordered. 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 that we do get wiser with age.

Neuroscientists are also finding that we are happier with aging. A recent US study found 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 learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.

【解析】

試題分析：本文主要講隨著年齡增長，并不是我們的各方面都在減弱，而有些方面的能力在增強(qiáng)，比如認(rèn)知能力、詞匯言語記憶、解決問題的能力及對幸福的感受等。

【1】A細(xì)節(jié)推理題。根據(jù)第二段when it comes to the important things, our brains actually get better with age.和she argues that some studies have found that our brain hits its peak between our 40s and 60s可知A正確。

【2】B細(xì)節(jié)推理題。根據(jù)第四段Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving.可知B正確。

【3】B細(xì)節(jié)推理題。根據(jù)最后一段as we get older we’ve learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.可知隨著年齡增長，就會意識到生命的短暫和快樂地重要。故選B.

【4】B主旨大意題。本文主要講隨著年齡增長，并不是我們的各方面都在減弱，而有些方面的能力在增強(qiáng)，故選B.
