A dream is one kind of experience.It seems as real as something that actually happens; in it the dreamer takes actions and reacts.During dreams the body is asleep but the thinking part of the brain is wide awake.In fact, it is more active than it sometimes is when the body is awake.
One group of researchers decided to see what would happen if they stopped people from dreaming.As soon as the electroencephalograph (脑电图仪) registered a dream pattern, researchers woke the dreamer.They did this all night for several nights, every time the person started to dream.
The experiment revealed that people who were unable to dream became nervous, easily upset, and hungrier.As soon as they were able to sleep without interruptions they lost their nervousness and became normal again; however, they then had more dreams than usual.It was as if they were catching up on their dreams.
To check these findings, the researchers carried on a control experiment.Again they woke people during the night, but during non-dreaming periods.These people did not change their daytime behavior.And when they were allowed to sleep without interruptions (打断), the number of their dreams did not increase.
Experiments like these have caused scientists to ask if dreams serve a purpose.Researchers know, for example, that some people who go for days without sleep will suffer from hallucinations (幻觉).Certain people even begin to show signs of mental illness.Some researchers believe that people become this way because they cannot have their usual numbers of dreams.According to this theory dreaming helps people to lead normal lives.

第1题：
有以下程序：
程序运行后的输出结果是（ ）。
A.10，One*Dream!
B.9，One*Dream!
C.9，One*World
D.10，One*World
正确答案：A
P是指向二维字符数组第二行One+Dream!的数组指针，所以长度是l0，打印输出的也是该字符串。 -
第2题：
有以下程序
#include<stdio．h>
#include<string．h>
main( )
{char str[][20]={“Qne*World”，“one*Dream!”}，*P=str[1 ]．
prinff(“％d，”，strlen(p))；printf(“％s＼n”，P)； ’
}
程序运行后的输出结果是
A．9，One*World S)
B.9，One*Dream!
C．10，One*Dream!
D．10，One*World
正确答案：C
解析：可以将二维数组str看成一个是一个特殊的一维数组，其元素也是一个数组。那么，str[O]为“One*World”，str[1]为“One*Dream!”。 -
第3题：
有以下程序：
include<stdio．h>
include<string．h>
main（ ）
{char str[][20][{"One*World"，"One*Dream!"}，*p=str[1]；
prinft("％d，"，strlen(p))；printf("％s＼n"，p)；
}
程序运行后的输出结果是（ ）。
A.9，0ne*World
B.9，0ne*Dream!
C.10，One*Dream!
D.10，Ome*World
正确答案：C本题输出两个结果，第一个是求字符串的长度。第二个是输出的字符串，数组的下标是从0开始的，所以当str取1的时候，应为“One*Dream!”。
