Choosing an Occupation
One of the most important problems a young person faces is deciding what to do. There are some people, of course, who from the time they are six years old know that they want to be doctors or pilots or fire fighters, but the majority of us do not get around to making a decision about an occupation or career until somebody or something forces us to face the problem.
Choosing an occupation takes time, and there are a lot of things you have to think about as you try to decide what you would like to do. You may find that you will have to take special courses to qualify for a particular kind of work, or you may find out that you will need to get actual work experience to gain enough knowledge to qualify for a particular job.
Fortunately, there are a lot of people you can turn to for advice and help in making your decision. At most schools, there are teachers who are professionally qualified to give you detailed information about job qualifications. And you can talk over your ideas with family members and friends who are always ready to listen and to offer suggestions.

Now youll hear two long conversations.
Conversation One
W: Ok, last night you were supposed to read an article about human bones. Are there any comments about it?
M: Well, to begin with, I was surprised to find out there was so much going on in bones. I always assumed they were pretty lifeless.
W: Well, thats an assumption many people make. But the fact is bones are made of dynamic living tissue that requires continuous maintenance and repair.
M: Right. Thats one of the things I found so fascinating about the article the way the bones repair themselves.
W: Ok. So can you tell us how the bones repair themselves?
M: Sure. See, there are two groups of different types of specialized cells in the bone that work together to do it. The first group goes to an area of the bone that needs repair. This group of cells produces the chemical that actually breaks down the bone tissue, and leaves a hole in it. After that the second group of specialized cells comes and produces the new tissue that fills in the hole that was made by the first group.
W: Very good. This is a very complex process. In fact, the scientists who study human bones dont completely understand it yet. They are still trying to find out how it all actually works. Specifically, because sometimes after the first group of cells leaves a hole in the bone tissue, for some reason, the second group doesnt completely fill in the hole. And this can cause real problems. It can actually lead to a disease in which the bone becomes weak and is easily broken.
M: Ok, I get it. So if the scientists can figure out what makes the specialized cells work, maybe they can find a way to make sure the second group of cells completely fills the hole in the bone tissue every time. Thatll prevent the disease from ever occurring.
Questions 19 to 22 are based on the conversation you have just heard.
19. What is the discussion mainly about?
【解析】對話一開始就談論人類骨骼的問題，女士說 But the fact is bones are made of dynamic living tissue that requires continuous maintenance and repair. 后面的對話都是針對這個話題展開的討論，可見整個對話討論的話題是骨頭的自我修復能力。
20. What is the function of the first group of specialized cells discussed in the talk?
【解析】男士解釋了第一組細胞的作用，第一組細胞生成一種化學物質分解骨組織，由此可見答案是They break down bone tissue.
21. What does the professor say about scientists who study the specialized cells in human bones?
【解析】女士說這種特殊細胞作用于人類骨頭的過程相當復雜，事實上，連研究人類骨頭的科學家都不能完全了解這個過程。從這一句中可以知道：In fact, the scientists who study human bones dont completely understand it yet. 所以答案即是這些科學家也不知道這些細胞如何工作。
22. According to the student, what is one important purpose of studying specialized cells in human bones?
【解析】學習這些人類骨頭中的特殊細胞的重要目的是為了學習如何預防骨頭疾病。從男士的這一句話中可看出：Thatll prevent the disease from ever occurring. 這樣可以在疾病發生之前預防疾病，可見符合題意。
Conversation Two
M: Hi Diana, mind if I sit down?
W: Not at all, Jerry. How have you been?
M: Good. But Im surprised to see you on the city bus. Your car in the shop?
W: No. Ive just been thinking a lot about the environment lately. So I decided the air will be a lot cleaner if we all use public transportation when we could.
M: Im sure you are right. The diesel bus isnt exactly pollution free.
W: True. Theyll be running a lot cleaner soon. We were just talking about that in my environmental engineering class.
M: What could the city do? Install pollution filters in all their buses?
W: They could, but those filters make the engines work harder and really cut down on the fuel efficiency. Instead they found a way to make their engines more efficient.
M: How?
W: Well, there is a material thats a really good insulator. And a thin coat of it gets sprayed on the certain part of the engine.
M: An insulator?
W:Y eah. What it does is reflect back the heat of burning fuel. So the fuel will burn much hotter and burn up more completely.
M: So a lot less unburned fuel comes out to pollute the air.
W: And the bus will need less fuel. So with the saving on fuel cost, they say this will all pay for itself in just six months.
M: Sounds like people should all go out and get some this stuff to spray their car engines.
W: Well, its not really that easy. You see, normally, the materials are fine powder. To melt it so you can spray a coat of it on the engine parts, you first have to heat it over 10000 degrees and then, well, you get the idea. Its not something you or I will be able to do ourselves.
Questions 23 to 25 are based on the conversation you have just heard.
Passage Two
People dreams four to six times a night. They dream while they are in the REM stage of sleep, which means rapid eye movement stage in ones sleep. Sleepers go into the REM stage about every 90 minutes. The first dream of the night may last about ten minutes. Each dream gets a little longer. The last dream of the night may be an hour long.
People need their dreams. Younger children spend more time dreaming. Babies spend almost half of their sleep in the REM stage.
One experiment showed that everyone needs to dream. Doctors gave some people sleeping pills. These sleeping pills didnt let them going to REM sleep. After a few nights without dreams, they began to feel bad. They became angry easily, they worried a lot, and they wanted to fight with everyone. Then they stopped taking the sleeping pills. They all began to dream all night for a few nights to catch up.
Why do people dream? Dreams give them time to find the answers to some of their problems. If they think they will have difficult problems the next day, they may spend more time on REM sleep the night before. In their dreams, they may find an answer to their problems.
Questions 29 to 31 are based on the passage you have just heard.
29.How often does a person dream each night?
【解析】文章一開始即交待了一個人一晚上要做夢四到六次。從第一句就可看出People dreams four to six times a night.因此，答案為 。
30.What is true according to this passage?
【解析】安眠藥會阻止人們進入REM睡眠狀態。These sleeping pills didnt let them going to REM sleep.可看出 項正確。
31.Why do people dream?
【解析】文中明確給出了答案Dreams give them time to find the answers to some of their problems.因為在夢中人可以找到自己的問題的答案。
Passage Three
O.K., everybody. Can we start the meeting now? Im Jeff Milton, the chairperson of the Graduation Committee for this year. Youve all been selected as representatives to plan the graduation ceremonies. Im sending around the sheet of paper for you to fill in your name and telephone number. Also, please write down what part of the ceremonies you would like to work on.
