李华刚下课，走出课堂就碰上Larry。

LH: Hey, Larry. 你刚下课啊？对了，我刚好要问你，今天你有没有见到Dave？

LL: Dave? No, I haven't seen him anywhere since professor Jones went off on him yesterday morning.

LH: Jones教授对Dave怎么啦？你说他went off on Dave? 那是什么意思呢？

LL: To go off on someone means to suddenly get very angry at someone. "To go off " can mean "to explode"- for instance, something like a bomb or a gun can go off.

LH: 噢，to go off on someone就是突然对某人大发脾气，就好像炸弹爆炸，枪支开火那样。那Jones教授为什么突然对Dave大发脾气呢？

LL: Dave asked Professor Jones if he could turn in a paper a few days late, and Professor Jones just went off on him.更多信息请访问：http://www.engbus.cn/

LH: Dave 怎么经常要求晚几天交报告呐？唉，也难怪Jones教授要go off on him对他发脾气了。Larry，你再给我举几个go off on someone的例子吧！

LL: Hmm, let me think. I remember when I was in Beijing I tried to pay a taxi driver, and he went off on me for several minutes. I had no idea why he was so angry. It turned out, what I gave him was a counterfeit note.

LH: 你给出租车司机假钞票，那他当然要对你大发脾气咯！

LL: Li Hua, have you ever gone off on someone here in the US?

LH: 我啊，我英文还不是很好，轻易不敢和人吵架。我只有对我过去那个同屋发了好几次脾气，因为她实在太脏，而且还想偷偷搬出去，就是为了想赖掉一个月的房租呢！

LL: She tried to cheat you out of a month's rent? If my roommate did that, I wouldn't just go off on him, I'd take him to court!
