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.
The stages of sleep take on ____
A) an irregular aspect.
B) a regular aspect
C) a punctual aspect
D) a similar aspect

听力原文： In many places in the world today, the poor are getting poorer while the rich are getting richer, and the programs of development planning and foreign aid appear to be unable to reverse this trend. Nearly all the developing countries have a modern part, where the patterns of living and working are similar to those in developed countries. But they also have a non-modern part, where the patterns of living and working are not only unsatisfactory, but in many cases are even getting worse.
What is the typical condition of the poor in developing countries？ Their work opportunities are so limited that they cannot work their way out of their situation. They are underemployed, or totally unemployed. Some of them have land, but often too little land.
Many have no land, and no prospect of ever getting any. There is no hope for them in the rural areas, and so they drift into the big cities. But there is no work for them in the big cities, of course no housing. All the same, they flock into the cities because their chances of finding some work appear to be greater there than in the villages. Rural unemployment then becomes urban unemployment.

A．The poor places are getting richer.
B．The rich places are getting richer.
C．The poor places are getting poorer.
D．Both B and C.
You do not remain at this deep fourth stage all night along, 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 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 that most dreams seem to occur.
Provided that you do not wake up during the first 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.
Which of the following does the passage mainly discuss？
A．Scientific methods of studying sleep.
B．Why humans require sleep.
C．The phases of sleep.
D．Why dreams occur during REM sleep.
W: Yes, it was fantastic. Now I know why it is listed together with the Nile River as one of the great natural wonders of the world. Here, want to see the picture I took？
M: Oh, what a view! It is even bigger than I had imagined. I remember reading about the Grand Canyon, and I think it said that it was formed suddenly when the earth' s crust split open during an earthquake.
W: Well, not that quickly. Look, here is the picture of the canyon, that fiver and its tributaries have been wearing the canyon floor away for ten million years.
M: Then the canyon is the result of swale erosion. I' 11 bet geologists have made some interesting discoveries here.
W: Not only the geologists, archaeologists have found the bones of extinct animals in caves in the canyon walls. In a cave one hundred and forty feet above the river, they found drift wood that dates back as far as thirty seven thousand years.
M: That means the river must have been a hundred and forty feet higher up when it carried the driftwood into the cave.
W: It' s very possible, but, of course, who knows. The Grand Canyon is full of mysteries. Wouldn't you like to go to Arizona some day？
M: You bet I would.

A．To the Nile River.
B．To the Museum of Natural History.

听力原文： (29)Some people don't like anything to be out of place. They are never late for work; they return their books to the library on time; they remember people's birthdays and they pay their bills as soon as they arrive. (29) Mr. Brown is such a person. Mr. Brown works in a bank, and lives on his own. His sister lives in the next town with her husband, and her son, Mark. Mr. (30) Brown doesn't see his sister or her family from one year to the next, but he sends them Christmas cards, and he hasn't forgotten one of Mark's seventeen birthdays.
Last week Mr. Brown had quite a surprise. He drove home from the bank at the usual time; driving neither too slowly nor too fast, he parked his car where he always parked it, out of the way of other cars, and he went inside to make his evening meal. Just then there was a knock at tbe door. When he opened it, he found a policeman standing there. Mr. Brown asked himself. "' Have I driven on the wrong side of the road？ Has there been some trouble at the bank？ Have I forgotten to pay an important bill？"
(31)"Hello, uncle," said the policeman, "My name's Mark. "

W: Well, not that quickly. Look, here is the picture of Colorado river. See way down at the bottom of the canyon, that fiver and its tributaries have been wearing the canyon floor away for ten million years.
M: Then the canyon is the result of swale erosion. I'll bet geologists have made some interesting discoveries here.
W: Not only the geologists, archaeologists have found the bones of extinct animals in caves in the canyon wails. In a cave one hundred and forty feet above the river, they found drift wood than dates back as far as thirty seven thousand years.
