Questions 26 to 30 are based on the following passage:
Sleep is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper, your sleep cycle is as follows. When you first drift off into slumber (安睡), your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing were slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.
You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear, to be replaced by the activity pattern of brain waves. Your eyes will begin to dart around under your closed eyelids (眼皮) as if you were looking at something occurring in front of you. This period of rapid eye movement lasts for some 8 to 15 minutes and is called REM sleep. It is during REM sleep period, your body will soon relax again, your breathing will grow slow and regular once more, and you will slip gently back from stage 1 to stage 4 sleep — only to rise once again to the surface of near consciousness some 80 minutes later.

A) stage 1 C) stage 4 B) stage 2 and stage 3 D) REM sleep

Questions 21 to 25 are based on the following passage:
We can make mistakes at any age. Some mistakes we make are about money, but most mistakes are about people. “Did Jerry really care when I broke up with Helen?” “When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?” “And Paul — why didn't I pick up that he was friendly just because I had a car?” When we look back, doubts like these can make us feel bad. But when we look back, it's too late.
Why do we go wrong about our friends — or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, “You're a lucky dog.” Is he really on your side? If he says, “You're a lucky guy” or “You're a lucky gal,” that's being friendly. But “lucky dog”? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the “dog” bit puts you down a little. What he may be saying is that he doesn't think you deserve your luck.
“Just think of all the things you have to be thankful for” is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.
How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says square with the tone of voice? His posture? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.
21.When the writer recalls the things that happened between him and his friends, he ____.
A) feels happy, thinking of how nice his friends were to him
B) feels he may not have “read” his friends' true feelings correctly
C) thinks it was a mistake to view Jim as a friend
D) is sorry that his friends let him down
22.By saying “You're a lucky dog.”, the speaker ____.
A) is just being friendly
B) expresses the same meaning as “You're a lucky guy.” or“You ' re a lucky gal.”
C) is humorous to apply the word “dog” to people
D) has a hidden jealous feeling behind the words
23.In listening to a person, the important thing is ____.
A) to notice his tone, his posture, and the look in his eye
B) to listen to how he pronounces his words
C) to check his words against his manner, his tone of voice, and his posture
D) not to believe what he says
24.If you followed the advice of the writer, you would ____.
A) weigh carefully what people say to determine their real meaning
B) get along well with people
C) trust what other people say
D) have no doubts about our friends
25.This passage tries to tell you how to ____.
A) avoid mistakes about both money and people
B) say things elegantly
C) avoid mistakes in understanding what people tell you
D) keep people friendly without trusting them
