设有程序片段:switch（sex) { case 'M': printf（“Male”); case 'F': printf（“Female”); default: printf（“error”); } 若sex的值为’F’，则程序输出结果是_______

A、{'name': 'yyy', 'Sex': 'male'}

B、{'Name': 'yyy', 'Sex': 'male'}

C、{'Name': 'xxx', 'Sex': 'male', 'name': 'yyy'}

D、错误

在以上签证中，sex那一栏可填的选项有

A、Female

B、Male

C、Man

D、Woman

以下程序中函数 fun 的功能是：统计 person 所指结构体数组中所有性别 (sex) 为 M 的记录的个数 ， 存入变量 n 中，并做为函数值返回。请填空：

#include <stdio.h>

#define N 3

typedef struct

{ int num;char nam[10]; char sex;} SS;

int fun(SS person[])

{ int i,n=0;

for(i=0;i<N;i++)

if( 【 14 】 =='M') n++;

return n;

}

main()

{ SS W[N]={{1, "AA", 'F'},{2, "BB",'M'},{3,"CC", 'M'}}; int n;

n=fun(W); printf("n=%d\n",n);

}

Our brains could be hard-wired to be male or female long before we begin to grow testes(丸)or ovaries(卵巢)in the womb. This discovery might explain why some people feel trapped in a body that's the wrong sex, and could also lead to tests that reveal the true "brain sex" of babies born with ambiguous genitalia(生殖器).

Till now, the orthodoxy among developmental biologists has been that embryos develop ovaries and become female unless a gene called SRY on the Y chromosome is switched on. If this gene is active, it makes testes develop instead. This switch is seen as the key event in determining whether a baby is a girl or a boy. Only after the gonads(性腺) form. and flood the body with the appropriate hormones, the theory goes, is the sex of our minds and bodies determined.

But in a study of mice, a team at the University of California, Los Angeles, has now found that males and females show differences in the expression of no fewer than 50 genes well before SRY switches on. "It's the first discovery of genes differentially expressed in the brain, "says Eric Vilain, who led the UCLA team. "They may have an impact on the hard-wired development of the brain in terms of sexual differentiation independent of gonadal induction."

Vilain is presenting details of seven of the 50 genes to the annual meeting of the American Society of Human Genetics in Baltimore this week. Three of these genes are dominant in females and four are dominant in males. The next step for Vilain and his team will be to show that the genes in question really do influence brain sexuality—and not just in mice. This is likely to be a much tougher proposition than merely showing there are differences in expression.

But if the findings are confirmed, they could one day yield blood tests that allow doctors to establish the brain sex of babies born with genitalia that share features of both sexes. At present doctors and parents have to guess which gender to assign for surgical "correction".

The first paragraph tells us that ______.

A．whether we will be male or female is determined by the brain, not the genitalia

B．some people consider themselves to be male but are in fact female physiologically

C．our brain sex is formed long after our testes or ovaries begin to grow

D．some people feel trapped because they have ambiguous genitalia

A．It's modern.

B．It's exciting.

C．It's comfortable.

D．It's abnormal.

听力原文：W: I'm worried about Monday's exam.

M: Take it easy. I'm sure you will do well if you take it easy and remain calm.

W: Is it all right if I use dictionaries?

M: You are not allowed to use them. I think.

W: Do you think I could discuss the questions with others during the exam?

M: I'm afraid that's impossible. Teachers would not allow that to happen.

W: May I bring some paper to write drafts?

M: Yes, that's all right, I suppose.

W: Thank you very much for the information.

Q8: What is the woman's problem?
