听力原文：M: Jean, were you able to get that report all typed up？
W: Not yet, Mr. Black. Mrs. Farnsworth asked me to type some letters for her. I'll be finished pretty quick and then I'll start on that.
M: Don't forget I need it first thing in the morning. I have to take it along to Chicago to the regional meeting.
W: Don't worry, I'll get it done. My husband's on a business trip too. He's in Detroit today, and tomorrow he'll be in Boston. So I'm planning to stay late. After it's typed up I'll leave it on your desk. I should be finished by 8:00 pm.
M: I'm sorry to keep you so late.
W: It's all right, Mr. Black. I don't mind at all. Besides, I can use a little extra money. My husband's birthday is next month. I want to buy him a new watch.
M: What kind are you going to get him, a Bulova？
W: No. I thought I'd get a Rolex, or an Elgin. I don't really know much about watches.
M: I've got one of those Seiko digitals. I really like it.
W: Do you think my husband would like one like that？
M: I'm sure he would. The only problem is that it's a little bit heavy.
W: If it's that good, I think I'll go ahead and get him one.
M: Well, at least he won't get a tie. That's what I usually get.
W: Remember, it's the thought that counts.

What makes a person a scientist?Does he have ways or tools of learning that are different from those of others?The answer is "no".It is not the tools a scientist uses but how he uses these tools that make him a scientist.You will probably agree that knowing how to use a power is important to a carpenter.You will probably agree,too,that knowing how to investigate,how to discover information,is important to everyone.The scientist,however,goes one step further,he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons.He also works to fit the answer he gets to many questions into a large set of ideas about how the world works.
The scientist's knowledge must be exact.There is no room for half right or right just half the time.He must be as nearly right as the conditions permit.What works under one set of conditions at one time must work under the same conditions at other times.If the conditions are different,any changes the scientist observes in a demonstration must be explained by the changes in the conditions.This is one reason that investigations are important in science.Albert Einstein,who developed the theory of relativity,arrived at this theory through mathematics.The accuracy of this mathematics was later tested through investigations,Einstein's ideas were shown to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.

—_______________.

When I was studying English at a training center in Washington D.C. in 1998， , I shareda house with two young Americans, Jim, and Steve. Jim was studying French and Steve Chinese, both at the Foreign Service Institute. We shared many things in common, but we also thought and acted quite differently. Steve was interested in speaking Chinese. He always tried every opportunity to talk with me with his very English-like pronunciation. I was often touched with his diligence. However, I wanted to practice English with him, too. So we often speak at the same time in the other &39;s mother tongue. Jim was fresh from college and the youngest of the three. He was going out all the time. The only time we met was at breakfast. There was a small round table in our kitchen, where we sat around to enjoy our food. Steve had Chinese fast food such as dumplings or noodles, and I ate bread and boiled eggs. But Jim often just drank a cup of tea because he had nothing in his bridge. He was too busy dating pretty French girls to do any shopping. I often offered him some of my food. But Steve told me in his poor Chinese that I didn&39; t need to do that. He said that it was Jim&39; s own fault and that it served him right. Although he was learning Chinese, hestill held his American senseof value.
Two years later, I returned to china. The three of us still keep in touch. Jim now works in a travel agency in Paris. He got married to one of the pretty girls. He wrote to tell us that now he can enjoy a delicious breakfast with his beautiful wife every morning in their comfortable living room. Steve wants to work in china. And V m helping him with this. I have introduced him to the dean of the OverseasSection of our university. He is very interested in Steve. He wants to know if Steve can work here teaching the overseas students Chinese. I have sent the messageto Steve. I&39; m sure he’ d be very happy to accept the job. However, I hope he could try harder to improve himself. Othervise, all the overseas studentswould speakwith his terrible pronunciation!
