Jenny: In fact, I'm in Class 5.
Alison: I just came here two weeks ago. Do you like the institute?

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.

Jenny: Good. I'm hungry.
