Ss: Mr./Miss…, You’d better not throw it away.

T: Why?

Ss: Because it can be reused.

T: (教师拿出一罐头瓶。) Here is a can. It’s not useful. S1, please throw it out of the window.

S1: Sorry. Mr./Miss…, I can’t do that. We must protect our environment and it can be collected and recycled.

T: What a greener person! (教师指着灯，然后做关灯手势。) Oh, the light is still on. S2, would you please turn it off?
