Question

【題目】 As we age, our ability to think and remember starts to become worse. But not everyone. Some of us are super-agers, who are over the age of 80 and have the brain of much younger people.

Scientists know that parts of the brain become smaller in size with age. But in super-agers that goes much slower. In her recent study, Emily Rogalski, a neuroscientist (神經科學家), showed that super-agers have young brains. The area of the brain for attention and memory was shown to be thicker in super-agers. “When we look at a super-ager’s brain, we see that it looks more like a 50-year-old brain than an 80-year-old one.”

Scientists say super-agers have several things in common, including an active lifestyle. Many travel and play sports. They are often big readers. And they usually have healthy relationships and spend time with friends. “Growing old,” she adds, “does not have to be depressing and sad. Perhaps, if we expect a little better from ourselves, we will understand that not all aging makes us doom and gloom (愁悶).” Rogalski jokingly said that super-agers do not grow on trees — meaning they are special and few. She says she wants to find out why a super-ager’s mind is working so well and not aging as quickly as most.

The science behind super-aging is a new, but growing field. Scientists in the research offer this advice as we age: Stay active. Learn new things. Challenge yourself. Develop healthy relationships.

B.In a love story.

C.In a health research report.

D.In a sports magazine.

【3】What can we infer from the passage?

B.Super-agers have several things in common, including an active lifestyle.

C.If people feel sad more often, they probably will live longer.

Answer 1

【答案】

【1】C

【2】C

【3】A

【4】B

【解析】

本文是一篇說明文，隨著年齡的增長，我們思考和記憶的能力開始惡化。但并不是每個人都是這樣。我們中的一些人的大腦衰老得更慢。科學家們指出，大腦的某些部分隨著年齡的增長而減小，但在超級老年人中，這個過程要慢得多。

【1】細節(jié)理解題，根據第二段第3句“In her recent study, Emily Rogalski, a neuroscientist (神經科學家), showed that super-agers have young brains.”可知，神經科學家艾米麗·羅加爾斯基的研究表明：超級老人有年輕的大腦，故選C。

【2】文章題材題。短文介紹了神經科學家的關于人的健康報告，故選C。

【3】細節(jié)理解題。根據第三段“She says she wants to find out why a super-ager’s mind is working so well and not aging as quickly as most.”可知，科學家還不知道超級老人的大腦為何工作得那么好而且比年輕人衰老得慢，故選A。

【4】篇章結構題。根據短文思路可知，作者認為超級老人的大腦的發(fā)展是在保持活躍、學習新事物、挑戰(zhàn)自我、發(fā)展人際關系的基礎上進行的，故選B。
