  Passage

  Biochemistry is a very specific area of chemical science. First of all, the purpose of biochemistry is to find out which chemicals in particular and, how interact with particular systems inside the human body and how they affect its functions. Another area of biochemistry is the determination of the way to effect functions of the body. And in particular we can say that biochemistry is the whole foundation of the pharmaceutical industry because all the drugs that we have on the market are derived as chemical components. And the purpose of biochemistry is to determine, whether some, component is going to be active or not. And is it going to be, efficient or not, and if it's going to affect some biological functions or not. Therefore biochemistry right now is very rapidly developing area because there is a high demand, for efficient and quickly, acting chemicals and quickly acting drugs. We can see that there is a lot of viruses and a lot of diseases which are developed at this particular time and therefore there is a high demand for new efficient agents. And one area of biochemistry which is of a particular interest is computer based analysis of chemical components, and computer based design of drug, agents. It has been proven that computer based design could be particularly efficient for the design of anti-viral components.

  Q1. According to the speaker, what is the study of biochemistry?

  Q2. Why does the speaker say that biochemistry is a rapidly developing field?

  Q3. What is the interesting area of biochemistry research?

  答案&解析:

  1. 答案:B

  解析:

  根據聽力原文中Biochemistry is a very specific area of chemical science. First of all, the purpose of biochemistry is to find out which chemicals in particular and, how interact with particular systems inside the human body and how they affect its functions.可知,生物化學研究的是人體的某一系統和他們如何運轉, interact with與interaction為同義替換,所以,答案為B。

  2. 答案:A

  解析:

  根據聽力原文中Therefore biochemistry right now is very rapidly developing area because there is a high demand, for efficient and quickly, acting chemicals and quickly acting drugs.可知,生物化學之所以是一個快速變化的領域,是因為人們對高效、快速見效的藥物需求,所以,答案是A。

  3. 答案:D

  解析:

  根據聽力原文中And one area of biochemistry which is of a particular interest is computer based analysis of chemical components, and computer based design of drug, agents.可知, 文中能聽到的是生物化學特別有意思的一個領域是基于電腦技術的藥物開發,所以,答案為D。

  聽力原文:

  Lecture

  Good morning, everyone. Today we will look at how to observe behaviour in research. In this lecture, I will briefly introduce two kinds of sampling, that is, time sampling and situation sampling.

  Now first, time sampling. Time sampling means that researchers choose various time intervals for their observation. Intervals may be selected systematically or randomly. Suppose we want to observe students' classroom behaviour. Then in systematic time sampling, our observations might be made during five 20-minute periods, beginning every hour. The first observation period could begin at 9 am, the second at 10 am and so forth. However, in random sampling, these five 20-minute periods may be distributed randomly over the course of the day. That is to say, intervals between observation periods could vary—some longer others shorter. One point I'd like to make is systematic and random time sampling are not always used in isolation. They are often combined in studies. For example, while observation intervals are scheduled systematically, observations within an interval are made at random times. That means the researcher might decide to observe only during 15-second intervals that are randomly distributed within each 20-minute period.

  Now let's come to situation sampling. Then, what is situation sampling? It involves studying behaviour in different locations and under different circumstances and conditions. By sampling as many different situations as possible researchers can reduce the chance that their observation results will be peculiar to a certain set of circumstances and conditions. Why? Because people or for that manner animals do not behave in exactly the same way across all situations. For example, children do not always behave the same way with one parent as they do with the other parent, and animals do not behave the same way in zoos as they do in the wild. So, by sampling different situations, a researcher can make more objective observations than he would in only a specific situation.

  Q1. What does the introduction say about observing behaviour in research?

  Q2. What's the difference between time sampling and random sampling?

  Q3. What is situation sampling?

  答案&解析:

  1. 答案:C

  解析:

  根據文中Today we will look at how to observe behaviour in research. In this lecture, I will briefly introduce two kinds of sampling, that is, time sampling and situation sampling.可知, 開場簡短介紹當中,講座發言人指出在研究觀察行為時,有兩種研究案例的方式,所以,答案為C。

  2. 答案:A

  解析:

  根據文中第二段先是談到如何進行time sampling到,后來轉折處常考,however之后談到However, in random sampling, these five 20-minute periods may be distributed randomly over the course of the day. That is to say, intervals between observation periods could vary—some longer others shorter.可知,time sampling和random sampling不同的是兩者觀察時間間隔的不同,所以答案選A。

  3. 答案:D

  解析:

  根據聽力原文中Now let's come to situation sampling. Then, what is situation sampling? It involves studying behaviour in different locations and under different circumstances and conditions. 可知,situation sampling主要是研究觀察總結人在不同環境、狀況下的行為,所以,答案為D。

  Conversation

  W: Hello, Ultimate Computers. May I help you?

  M: Yes, this is Jack Kordell from Hunter's Office Supplies. May I speak to Elaine Strong, please?

  W: I'm sorry, but she's not in right now.

  M: Okay, do you know when she'll be back?

  W: Uh, yes, she should be here later on this afternoon maybe about 4:30. May I take a message?

  M: Yes. Ms. Strong sent me a brochure detailing your newest line of laptop computers with a description of other software products, but there wasn't any information about after-sales service.

  W: Oh, I'm sorry. Would you like me to fax that to you?

  M: Yes, but our fax is being repaired at the moment, and it won't be working until around 2:30. Hum . . . could you try sending that information around 3:30? That should give me time to look over the material before I call Ms. Strong, say, around 5:00.

  W: Sure. Could I have your name, telephone number, and fax number, please?

  M: Yes. Jack Kordell and the phone number is 560-1287. And the fax number is 560-1288.

  W: All right. I'll be sure to send you the fax this afternoon.

  M: Okay, goodbye.

  Q1. Why can't Elaine Strong answer the phone?

  Q2. What does the man want the secretary to send?

  Q3. What will the woman probably do?

  答案&解析:

  1. 答案:B

  解析:

  根據對話中女士的那句W: I'm sorry, but she's not in right now.可知,Elaine Strong不能接電話的原因是她不在辦公室。所以,答案為B。

  2. 答案:A

  解析:

  根據對話中男士在轉折處but后說的but there wasn't any information about after-sales service.可知,男士想要的是售后服務方面的信息,所以答案為A。

  3. 答案:D

  解析:

  根據對話中女士All right. I'll be sure to send you the fax this afternoon.可推知,女士接下來一定會給男士(Mr. Kordell) 發傳真。
