我们中国有句古话：知足者常乐，可是真正要做到知足也是很难的。人的欲望都是无穷无尽的，所以如何才能抵住诱惑成为了很多人的心理课堂。今天我们讲的这个习语是To push one's luck得寸进尺

下面我们通过对话来了解一下：

Larry 和李华正在课间休息的时候聊天，李华说她又想逃课。

LH: Larry, 我已经好久都没有为我的论文做研究了。我想今天不去上Wilkins教授的课而去图书馆。

LL: I dunno, Li Hua. You'll really be pushing your luck if you miss class again.

LH: Pushing-my-luck? Pushing是推的意思，luck是运气，我不懂耶！pushing my luck是什么意思。

LL: I said you will be pushing your luck. "To push your luck" means to take a chance when you've already done something risky.

LH: 噢，pushing-your-luck就是已经做了冒风险的事，可是啊！还想再进一步碰碰运气，是这个意思吗？

LL: That's right. The first two times, the professor didn't give you any trouble. But every time you miss a class, you are taking an even bigger risk. You are pushing your luck.

LH: 对噢，那两次没去上课，教授没说什么。要是我今天再不去上课，万一教授不高兴，我不就麻烦了吗？ Larry，你不也是这样吗？你那台车，煞车都坏了，你还到处开，不也是碰运气，希望它不出事吗？

LL: That's right. One day, I was almost in a car wreck, so I decided to stop pushing my luck and have the brakes fixed. I was so stupid.

LH: 我还不知道你差一点出车祸呢！哎呀，你看，你非要push your luck，非要到差一点出车祸的时候才去修车。真危险！ Larry，这么说，to push one's luck只能指冒风险，碰运气吗？

LL: Generally yes. But sometimes, if someone keeps asking you for favors, you might tell them "don't push your luck!"

LH: 我最近就碰到这么一个人，我帮了她一点忙，她就没完没了了，要求一个接一个。下回我就可以对她说：Don't push your luck! 对了，Larry，我还真想要你帮个忙，我能再借你的电脑用吗？这不算是push my luck吧？

LL: No, of course not. You're welcome to use my computer.

LH: 谢谢，Larry，你总是那么大方。我今天下午能借你的车吗？

LL: Yeah, OK... I guess...

LH: 那我能不能把你的电脑搬回家用一个礼拜呢？

LL: You're pushing your luck, Li Hua!

LH: 哈哈... 跟你开玩笑嘛！
