Question

Do you know that women’s brains are smaller than men’s? Normally the women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent（聪明的） than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain is made up of “grey matter” and “white matter”. While men have more of the white matter, the amount（数量）of “thinking” brain is almost the same in both men and women.
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes（性别）. As white matter is the key to spatial（空间的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses（胎儿）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
小题1:Which of the following is TRUE according to Paragraph 1?

A．Grey matter controls thinking in the brain.

B．Men’s brain is 10% less than women’s.

C．Grey matter plays the same role as white matter.

D．Men and women have the same amount of white matter.

A．Men have weaker spatial abilities.

B．Women do not need to tell directions.

C．Women prefer doing many things at a time.

D．Women do many jobs at a time better than men.

小题3:What can you learn from Paragraph 4?

A．Our children needed more spatial skills.

B．Women may have more feelings than men.

C．Young boys may be stronger than young girls.

D．More women take up jobs requiring speech skills.

小题4: The passage is mainly about _______.

A．ways of being more intelligent

Answer 1

小题1:A
小题1:D
小题1:D
小题1:C

小题1:A 推理判断。由第一段最后两句可知。尽管男人有更多的后者（白质），但是大脑的思考部分（当然是灰质）的量男女几乎完全相等。A有很大的迷惑性，但仔细一看文章中说的是平均。
小题1:D 推理判断。可采用排除法。女人在同时完成多项任务上有优势，并不是说女人喜欢同时干许多事情，因此A 错。C 、D明显与文章内容不符。
小题1:D 推理判断。由more men take up jobs that require good spatial skills, while more women speech skills（while more women take up jobs that require speech skills.）一句可知。
小题1:C . 考查文章大意。本文主要讲述科学家对男女两性大脑的研究，故选C。
