原文如下：
Narrator
Listen to part of a conversation between a student and a librarian.

Student
Hi, um…, I really hope you can help me.

Librarian
That’s why I’m here. What can I do for you?

Student
I’m supposed to do a literature review for my psychology course, but um… having a hard time
finding articles. I don’t even know where to start looking.

Librarian
You said this is for your psychology course, right? So your focus is on …

Student
Dream Interpretation.

Librarian
Well, you have a focus, so that’s already a good start. Hmmm… well, there’re a few things… oh
wait… have you checked to see if your professor put any material for you to look at on reserve?

Student
Aha, that’s one thing I did know to do. I just copied an article, but I still need three more on my
topic from three different journals.

Librarian
Let’s get you going on looking for those then. We have printed versions of twenty psychology
journals in the Reference Section. These are the ones published within the last year. Then I think
about it… there’s a journal named Sleep and Dream.

Student
Oh, yeah, the article I just copied is from that journal, so I’ve got to look at other sources.

Librarian
Ok, actually, most of our materials are available electronically now. You can access psychology
databases or electronic journals and articles through the library’s computers, and if you want to
search by title with the word ‘dream’ for example, just type it in and all the articles with ‘dream’
in the title will come up on the screen.

Student
Cool, that’s great! Too bad I cannot do this from home.

Librarian
But you can. All of the library’s databases and electronic sources can be accessed through any
computer connected to the university network.

Student
Really?! I can’t believe I didn’t know that. It still sounds like it’s going to take a while though, you
know, going through all of that information, all of those sources.

Librarian
Maybe, but you already narrow your search down to articles on Dream Interpretation, so it
shouldn’t be too bad. And you probably notice that there’s an abstract or summary at the top of
the first page of the article you copied. When you go into the databases and electronic sources,
you have the option to display the abstracts on the computer screen, skimming those to decide
whether or not you want to read the whole article should cut down some time.

Student
Right, abstracts! They’ll definitely make the project more durable. I guess I should try out the
electronic search while I’m still here then, you know, just in case.

Librarian
Sure, er… that computer’s free over there, and I’ll be here till five this afternoon.

Student
Thanks, I feel a lot better about this assignment now.

红色部分表示什么呢？？abstract不应该使事情变得简略么？为什么还持久嘞？？
gter都做过这个题吧。哪位解释一下。
谢谢！
