[不定项选择题]共用题干
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 of 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一the link between the two halves of the brain.
The two halves are linked by a trunk line 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 word-handling, 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 these differences correspond with the differences in the hemispheric trunk line,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 subjects 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.
Biologists are conducting research where psychologists have given up.
A.Right
B.Wrong
C.Not mentioned

Good evening, ladies and gentlemen, and welcome. I’m sure we have all heard the expression "Think Green". Tonight we are going to talk about ways that we can "Act Green" in our everyday lives.

Whimsical Nature endowed
the Moncton region in Southeastern New Brunswick with an enviable bonanza of
oddities. On the seashore at Hopewell Cape, strange reddish rock formations rise
like giant Polynesian heads eighty feet in the air--monuments sculpted by tides
and winds and frost over countless centuries to fill the aboriginal Indians with
awe and inspire their legends. The high domes of some statues are thatched with
balsam fir and dwarf black spruce, which always prompts children to ask how the
trees got up there.
At Demoiselle Creek a few milts from
Hillsborough is a subterranean lake of undetermined size, low-roofed by dripping
stone icicles. The white gypsum floor of the lake emerges startlingly visible
through the clear water. To step into the cavern entrance on a hot summer day is
like unexpectedly walking into a cold storage plant.
When you
first glimpse the Peticodiac River at Moncton you may
A. the Fundy tide
B. the huge natural rock monuments
C. strange noises in the mountains
D. the hidden caverns
