    I have a good {#blank#}1{#/blank#} at school. She is a girl. {#blank#}2{#/blank#} name is Lucy. We are in the same grade. But we are not in the same class. Lucy's brother is a student, {#blank#}3{#/blank#}. {#blank#}4{#/blank#} name is Tom. {#blank#}5{#/blank#} is a good boy. He is fifteen.

A: You must be really {#blank#}1{#/blank#} about leaving for America tomorrow, Li Ping!

B: Yeah. But I'm a bit nervous.

A: Nervous about what?

B: I don't know many of the {#blank#}2{#/blank#} and manners in the US. Could you give me a hand?

A: Sure.

B: What {#blank#}3{#/blank#} do they have in America?

A: Well, it's important to be on time when you're invited for dinner. It's {#blank#}4{#/blank#} to arrive late. Americans expect their guests to be on time.

B: Then how long may I stay there?

A: After the meal, don't leave at once. Or you seem to have come only for the meal. When your friends seem to be getting tired and running out of things, it's time to leave. The next day, call or write a thank-you note to say how much you {#blank#}5{#/blank#} the evening.
