       Two foreign students are sitting in a restaurant waiting to be served. The waiter is very busy with other

customers. After a few minutes, one student turns to the other and begins to talk.

Jenny: The service is really slow here.

Alison: Yeah, I hope the waiter comes soon. I have a class at two o'clock.

Jenny: Me, too. I recognize that English book. You must be a student at the English Language Center.

Alison: Yeah. I'm in Class 4. Are you studying there?

Jenny: In fact, I'm in Class 5.

Alison: I just came here two weeks ago. Do you like the institute?

Jenny: It's pretty good. I think I've learned a lot of English.

Alison: Yeah. I only wish the classes were a little smaller, though, because we can't get enough chance to talk.

           But I like my teachers a lot.

Jenny: How long are you going to be here?

Alison: About a year, but sometimes I feel like (想要) going home.

Jenny: You'll get used to it. Where are you from?

Alison: Thailand. How about you?

Jenny: Canada. I'm only staying here three more months. Then I'll go to Columbia University in New York.

Alison: By the way, my name's Alison.

Jenny: Hi. I'm Jenny.

Alison: Hi. Oh, here comes the waiter. It looks like we're going to get served.

Jenny: Good. I'm hungry.
