TEXT C
Women’s minds work differently from men’s. At least, that is what most men are convinced of. Psychologists view the subject either as a matter or frustration or a joke. Now the biologists have moved into this minefield, and some of them have found that there are real differences between the brains of men and women. But being different, they point out hurriedly, is not the same as being better or worse.
There is, however, a definite structural variation between the male and female brain. The difference is in a part of the brain that is used in the most complex intellectual processes-the link between the two halves of the brain.
The two halves are linked by a trunkline of between 200 and 300 million nerves, the corpus callosum. Scientists have found quite recently that the corpus callosum in women is always larger and probably richer in nerve fibres than it is in men. This is the first time that a structural difference has been found between the brains of women and men and it must have some significance. The question is “What？”, and, if this difference exists, are there others？ Research shows that present-day women think differently and behave differently from men. Are some of these differences biological and inborn, a result of evolution？ We tend to think that is the influence of society that produces these differences. But could we be wrong？
Research showed that these two halves of the brain had different functions, and that the corpus callosum enabled them to work together. For most people, the left half is used for wordhanding, analytical and logical activities; the right half works on pictures, patterns and forms. We need both halves working together. And the better the connections, the more harmoniously the two halves work. And, according to research findings, women have the better connections.
But it isn’t all that easy to explain the actual differences between skills of men and women on this basis. In schools throughout the world girls tend to be better than boys at “language subjects” and boys better at maths and physics. If 〖WTHZ〗these differences〖WTBZ〗 correspond with the differences in the hemispheric trunkline,there is an unalterable distinction between the sexes.
We shan’t know for a while, partly because we don’t know of any precise relationship between abilities in school subject and the functioning of the two halves of the brain, and we cannot understand how the two halves interact via the corpus callosum. But this striking difference must have some effect and, because the difference is in the parts of the brain involved in intellect, we should be looking for differences in intellectual processing.
71. Which of the following statements is CORRECT？
A.Biologists are conducting research where psychologists have given up.
B.Brain differences point to superiority of one sex over the other.
C.Results of scientific research fail to support pupular belief.
D.The structural difference in the brain between the sexes has long been known.
In one study, researchers examined the brain of a learning disabled person who had died in an accident. They found two unusual things. One involved cells in the left side of the brain, which control language. These cells normally are white. In the learning disabled person, however, these ceils were gray. The researchers also found that many of the nerve ceils were not in a line the way they should have been. The nerve cells were mixed together.
The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind proposed that learning disabilities mainly resultes from problems in the left side of the brain. He believed this side of the brain failed to develop normally. Probably, he said, nerve cells there didn't connect as they should. So the brain was like an electrical device in which the wires were crossed.
Other researchers didn't examine brain tissue. Instead, they measured the brain's electrical activity and made a map of the electrical signals.
Frank Dully experimented with this technique at Children's Hospital Medical Center in Boston. Dr. Duffy found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Dr. Dully said his research is evidence that reading disabilities involve damage to a wide area of the brain, not just the left side.
Scientists found that the brain cells of a learning disabled person differ from those of a normal person in ______.
A．structure and function
B．color and function
C．size and arrangement
D．color and arrangement

听力原文：M: I'm doing some research into the French revolution.
W: Oh, I did some on that last year.
M: Why do you think I'm here! Could you suggest some interesting and useful sources？
W: Sure. I found "Voices from the French Revolution" by Henri Le Brun to be very useful, as well as extremely interesting and well written.
M: What makes it so good？
W: Well, he took extracts from diaries kept by people involved in the revolution. They re ally give you an idea of how it felt to live in France during that time.
M: It sounds great. Why haven't I heard of it before？
W: Well, it's only just been translated from the French original and none of the professors have added it to their booklists yet. I used the French version and translated passages myself.
M: I see. I have been told that "The French Revolution" by Victoria Jones is useful.
W: I didn't find it very useful. I mean, there was nothing in it that you can't find else where. On the other hand, it's cheap, because it's available in paperback, and you can buy it at many bookshops.
M: What about using resources available on the Internet？
W: I used the Internet for my research, but I didn't find it very helpful. Many of the web sites were too small to contain much detailed information. Others provided links to other websites, but I found myself spending a lot of time following links and not finding much information.
M: Yes, I've run across that problem myself.
W: You could try the new edition of William Wright's book. It has the same title as Victoria Jones' book. It only came out a couple of months ago and I haven't seen a copy yet. A lot of it has been rewritten or consists of additional material recently found in French archives.
M: Thanks for your help. I'll go to the bookshop and see if I can find the books you've recommended.
W: when does your research have to be completed by？
M: Well, the essay is due in six weeks, so I'll try to finish the research in four, giving me two to write the essay.
W: Good luck!
