There are other important differences between two sexes.As white matter is the key to spatial 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 direction 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 as young as one.A boy would try to climb a barrier before him or push it down while a girl would attract 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.
If all this disappoints you, it shouldn’t.“The brain changes throughout our lives according to what we do with it.” says a biologist.

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists , do you have questions of your own about science?”
After a long pause, a boy raised his hand, “Have you ever seen a grasshopper eat? When I try eating leaves like that, I get a stomachache. Why?”
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before” or coming up with more questions or ideas.
Never push a child to “Think”. It doesn’t make sense. Children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.
Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
31. According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.
A. to let them see the world around B. to share the children’s curiosity
C. to explain difficult phrases about science D. to supply the children with lab equipment
