Animals seem to have the sense (本能) to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant（香的） flavor (味道) was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．

In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria（自助） feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．

So, in selecting food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”, which humans soon lose. Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-established（长期养成的）habits．Some people eat foxes, dogs and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．

53．The expression “the habit” in paragraph 1 refers to drinking water which _______．

A. has no smell    B. is tasteless    C. has vitamins   D. is flavored (有味道的)

A．adults know better than babies what kind of food are good for their health

B．adults usually cannot resist (抵制) the temptation (诱惑) of various delicious foods

C．adults' eating habits are closely related to the social and cultural customs

D．adults have more choices of food than babies in eating patterns小题2:The author implied in the passage that most of us _______．

A．eat a balanced diet

B．choose the food that is of nutrition

C．have the habits influenced by the surroundings

D．like to eat the food with a fragrant flavor．小题3:As far as their eating habits are concerned, babies and rats are similar in that _______．

A．both have the wisdom to choose a balanced diet

B．both prefer flavored food and drink

C．both have the same eating patterns

D．both develop a taste for the same kinds of flavors

函数ReadDat()的功能是实现从文件ENG49.IN中读取一篇英文文章，存入到字符串数组xx中。请编制函数encryptChar()，按给定的替代关系对数组xx中所有字符进行替代，仍存入数组xx的对应的位置上，最后调用函数WriteDat()把结果xx输出到文件PS49.DAT中。
替代关系；f(p)=p*11 mod 256 (p是数组xx中某一个字符的ASCII值，f(p)是计算后新字符的ASCII值)，如果原字符是大写字母或计算后f(p)的值小于等于32，则该字符不变，否则将f(p)所对应的字符进行替代。
注意：部分源程序已给出。
原始数据文件的存放格式是：每行的宽度均小于80个字符。
请勿改动主函数main()、读函数ReadDat()和写函数WtiteDat()的内容。
试题程序：
#include＜conio.h＞
#include＜stdio.h＞
#include＜string.h＞
#include＜ctype.h＞
unsigned char xx[50] [80];
int maxline=0;
int ReadDat(void);
void writeDat(void);
void encryChar()


void main()

clrscr();
if(ReadDat())

print f ( "数据文件ENG49.IN 不能打开! \n\007" );
return;

encryChar();
WriteDat();

int ReadDat(void)

FILE *fP;
int i=0;
unsigned char *p;
if((fp=fopen("ENG49.IN","r"))==NULL)
return 1;
while(fgets(xx[i],80,fp)!=NULL)

p=strchr(xx[i],’\n’);
if(p) *p=0;
i++;

maxline=i;
fclose(fp);
return 0;

void WriteDat()

FILE *fp;
int i;
fp=fopen("ps49.dat","w");
for(i=0;i＜maxline;i++)

printf("%s\n",xx[i]);
fprintf(fp,"%s\n",xx[i]);

fclose(fp);
