题目内容
13．Go into a busy bookstore and you will notice that the women are reading about fashion，beauty or friendship and the men are reading about cars，sport or technology．This should not be a surprise．After all，these choices are quite typical for women and men-women like working with people while men enjoy working with tools，objects and materials．When we look at young babies，we see that baby boys and girls show the typical hobbies at a very early age．A 12-month baby girl will look longer at people while boys of the same age look longer at toys．
So where do these differences between men and women come from？Scientists believed that parents had a lot of influence（影响） on their children．But many scientists now believe that the answer is also in the amount of man and woman hormones（激素） in the mother's body before a child's birth．Study has shown that this leads to three types of brain（大脑类型）：type S，type E and type B．People who are born with a type S or man brain are interested in objects．They are good at building and using tools and working out how things work．People with a type E or woman brain are good at understanding other people's feelings and treating people with great care．Others are born with both man and woman brains-this is called the type B or balanced brain．
Perhaps the most important thing that the scientists found out was that sex（性别）doesn't decide the type of brain you have．Not all men have the type S brain，and not all women have the type E brain．But on average，more men than women have a type S brain，and more women than men have a type E brain．
So does this mean that one type of brain is better than another？No，not at all．Some people find that some things are easier to do than others because they are born to be interested in them．They are good at doing certain things naturally．Scientists hope that understanding how people are born with different types of brain can help make all of us more open to the difference．
50．The underlined word"typical"in the first paragraph probably means"A"．
A．common
B．crazy
C．secret
D．strange
51．Which of the following is true according to the passage？B
A．A child's birth decides the difference between boys and girls．
B．Baby girls are more interested in people than baby boys．
C．More men than women have better types of brain．
D．Sex decides the type of brain．
52．What does the passage mainly talk about？B
A．Child's birth and sex．
B．Types of brain and likes．
C．Parents'difference and influence．
D．Young babies and their interests．
分析 文章大意：主要介绍了由父母激素对孩子的影响，孩子有不同的兴趣爱好．他们天生对什么感兴趣．他们很自然擅长做某件事情．科学家们希望了解人们是如何形成不同类型的大脑．
