情景对话
（At a party）
Jennifer: What are those guys doing?

Billy: I don't know, but it looks like they've got ants in their pants.

Jennifer: They've all got two left feet, that's for sure.

Billy: I know! It's that dance machine from Japan, Dance Dance Revolution.

Jennifer: Japanese people need a machine to teach them how to dance?

Billy: I guess it's more fun than just playing video games all the time.

珍妮花：那些人在干嘛？

比　利：我不知道，他们看起来手忙脚乱的。

珍妮花：可以确定的是他们都笨手笨脚的。

比　利：我知道了！那是日本来的跳舞机“跳跳革命”。
