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 exercises — and as a result, we are aging unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why {{U}} {{U}} 1 {{/U}} {{/U}}healthy farmers in northern Japan appeared to he losing their ability to {{U}} {{U}} 2 {{/U}} {{/U}}and reason at a relatively early age, and how the process of {{U}} {{U}} 3 {{/U}} {{/U}}could be slowed down.
With a team of {{U}} {{U}} 4 {{/U}} {{/U}}at Tokyo National University, he set {{U}} {{U}} 5 {{/U}} {{/U}}measuring brain volumes of a thousand people of different ages and {{U}} {{U}} 6 {{/U}} {{/U}}occupations.
Computer technology {{U}} {{U}} 7 {{/U}} {{/U}}the researchers to obtain precise measurements of the {{U}} {{U}} 8 {{/U}} {{/U}}of the front and side sections of the brain, {{U}} {{U}} 9 {{/U}} {{/U}}relate to intellect and emotion, and determine the human character. (The {{U}} {{U}} 10 {{/U}} {{/U}}section of the brain, which controls {{U}} {{U}} 11 {{/U}} {{/U}}like eating and breathing, does not {{U}} {{U}} 12 {{/U}} {{/U}}with age, and one can continue living without intellectual or emotional {{U}} {{U}} 13 {{/U}} {{/U}}.)
Contraction of front and side parts — as cells die {{U}} {{U}} 14 {{/U}} {{/U}}— was observed in some {{U}} {{U}} 15 {{/U}} {{/U}}in their thirties, but it was still not {{U}} {{U}} 16 {{/U}} {{/U}}in some sixty-and seventy-year-olds.
Matsuzawa {{U}} {{U}} 17 {{/U}} {{/U}}from his tests that there is a simple {{U}} {{U}} 18 {{/U}} {{/U}}to the contraction normally {{U}} {{U}} 19 {{/U}} {{/U}}with age — {{U}} {{U}} 20 {{/U}} {{/U}}the head.

单选题

A. otherwise
B. clockwise
C. likewise
D. anywise

【正确答案】 A

【答案解析】这是一个比较有难度的题目，涉及比较严密的推理过程。由文章第一段可知，大脑不勤用，人就老化快。在此认知基础上，结合该文第二段，我们可以反推：人不健康，早早地就会丧失思维推理的能力。因此要补全的空缺后面有一个单词healthy，它是“健康的”之意思，因此我们知道，要补全的空缺必须是一个能够否定healthy的单词，这样才能得到“不健康的”这个意思，所以显而易见要选择A，即otherwise(“否则，本来应该是”之意思)。

单选题

A. consider
B. meditate
C. think
D. contemplate

【正确答案】 C

【答案解析】由该空缺后面的and reason我们得知该空缺要填入一个表示“思维考虑”意思的单词，我们选择C，因为consider虽然有“思维考虑”的意思，但其是及物动词，与此处要求一个不及物动词矛盾，而meditate是“沉思、冥想”的意思，尤其是指在宗教方面，contemplate也是“沉思、凝视”的意思。

单选题

A. ageing
B. age
C. aged
D. to age

单选题

A. collegers
B. collegians
C. colleges
D. colleagues

单选题

A. up
B. to
C. out
D. about

【正确答案】 D

【答案解析】这是一个词组意思区别题目。set about表示“开始，着手”，后面接动名词，符合题意。应选D。set out表示“出发、动身”，当它作“打算、试图”意思时，一般接动词不定式，即说成“set out to do sth．”。set up表示“竖立，升高”。set to的意思是“开始起劲地干，开始狼吞虎咽地吃”，是一个副词性短语，不修饰其他词语，比如说“We all set to and got the place cleaned up in no time”。
