美国习惯用语：Don’t have a cow 别着急

今天Michael到李华的宿舍串门，李华正在到处找她的眼镜。
　　M: Hey, Li Hua, what are you doing?
　　L: 哎哟，我在找我的眼镜，急死人了，找不到眼镜我怎么上课啊？

M: Calm down. Li Hua, don’t have a cow. I’m sure you’ll find them.
　　L: 你说什么？Don’t have a cow? Cow, 这不是"母牛"的`意思吗？哎，我这儿是学生宿舍，怎么能养母牛呢？

M: No, I said "don’t have a cow", it means don’t get too excited about something. I’m sure you’ll find your glasses if you are patient enough.
　　L: 噢，我懂了，你是让我耐心点儿。你叫我Don’t have a cow, 意思就是别着急、别慌，可是，Don’t have a cow字面的意思明明是"别有母牛"。这跟"别惊慌"一点关系也没有，好奇怪哟！

M: Yeah, it is a little strange, but we still say it.
　　L: 好吧，就听你的， I won’t have a cow, 再想想看，我可能把眼镜放在什么地方了。
　　M: Well, where did you see them last?
　　L: 我记得昨晚睡觉前把眼镜放在床边桌子上了。

M: Have you looked under the bed?

L: 有啊，我在床底下找过了，让我再看看。哎呀，你还真说对了，就在床底下呢！
　　M: See, I told you not to have a cow and I was right.
　　L: 可是，Michael, 你肯定平时也有惊慌失措的时候。比方说，要是我对你说，我把你的电脑弄坏了，你肯定会have a cow。
　　M: Yes, I would have a cow because I can’t afford to buy a new one. Hey, Li Hua, You didn’t really break my computer, did you?
　　L: Don’t have a cow! 我是在跟你开玩笑啦！
