二年级诗配画Narrator
Listen to a conversation between a student and an employee in the campus computer center.
Computer center employee
Hi, what can I help you with today?白鞋子
Student
Hi, um, I wanted to—you e, the thing is, I don't know much about computers, so I was wondering if, uh, if there's a class so I can learn how to u computers, like to write papers for my class.
Computer center employee
Oh, um, we don't really offer a cour for beginners, since most students already have computing experience. But all the computers in our labs have a general tutorial installed on them. You could just go there and run it.
Student
And the tutorial explains everything? I mean, it might sound strange but I've never ud a computer.
Computer center employee
大唐皇帝李治 Well, all the computer labs on campus are staffed with student assistants, and I'm sure that any one of them would be more than willing to get you started.
Student
Yeah? That sounds good. But is it expensive?
Computer center employee
No, in fact, it won't cost anything; it's one of the rvices of the computer center.
Student
That's great. How do they—I mean, how do I get in touch with the student assistants? Should I just go to a computer lab and ask whoever's there?
Computer center employee
Sure, you could do that, or I can let you have a list of names of the students who are assistants in the labs. You might know one of them.
Student
Actually, I think I'd prefer someone I don't know, um, so I can ask Is there anyone you'd recommend?
Computer center employee
All of our student assistants are really knowledgeable about computers. I mean, they have to be, in order to work in the It doesn't mean that they're necessarily good at but you probably won't be a beginner for very long.
Student
Hope not.
Computer center employee
And I just thought of something el. The bookstore has a lot of books on computers-there might be one for people like you, I mean, people who don't have a lot of experience with computers. I actually bought one for my father so he could learn how to u e-mail, basic word processing, that sort of thing—and it worked pretty well for him.
Student
OK, I'll try that, too. And if the bookstore doesn't have it, they can just order it for me?
Computer center employee
永璇
Right. Now is there anything el I can help you with today?
Student
Uh, just the list of names and the times they're working. I'd like to get going on this as soon as possible.

Lecture 1
Narrator
Listen to part of a lecture in an economics class.
Professor

When attempting to understand international trade, some things em so obvious that they can hardly be controverted, and other points that are important are invisible unless you've thought about the subject carefully.
Consider the following: if there's an increa in imports, let's say, um, let's say imports of furniture, and the domestic producers of furniture find this new competition very difficult and are cutting production and employment, then it ems obvious and easy to understand and many people conclude from this that increasing imports will cau generally greater unemployment at home.

What is not so obvious is that how much we import and how much tho are interdependent and you can't understand the one without the other. But the exports that are generated are not easily discernable, so most people don't e them. They e only the imports of furniture rising and employment in domestic furniture production falling.
So as a result, many people argue that we ought to protect jobs by limiting imports—eith
er by tariffs, quotas, regulations, or whatever—without realizing that this also has the effect of reducing potential future exports to the rest of the world, things that we can produce very, cost effectively and therefore profitably.
The fundamental proposition in international economics is that it makes n to import tho things that can be produced more economically abroad than at home and export things to the rest of the world that we can produce more cost effectively than produced elwhere in the world. Therefore, if we limit imports, we put ourlves in danger of not being able to export.
The details of this relationship will take much longer to explain than I can fully go into now but the point of the matter is that gains—the benefits of gains—from international trade result from being able to get things cheaper by buying them abroad than you can make them at home. Now there're some things that we can make at home that we can do more economically than they can do abroad.
