小时候大家一般都不爱读书，因此课堂上老师的话大多都是“一个耳朵进一个耳朵出”了，这句话也可以说成：“左耳进右耳出。”美国人在这个说法上和中国人的表达是一模一样。

在英文中“左耳进右耳出”可以用“go in one ear and out the other”来表示，我们来看两个例子：

I told Sally it was foolish to marry that man, but it went in one ear and out the other. Now she wishes she’d listened to me. He drinks and gambles¹ and she wants to leave him. 我告诉萨莉嫁给那个男人很愚蠢，但她对我的话真是左耳进右耳出。现在她后悔当初没有听我的。她的丈夫不仅酗酒还赌博，她想要离开他了。

How many times have I told you to get to work on time. But my words justgo in one ear and out the other. So I don’t have any choice but to fire you. 我已经告诉你多少次了，要按时上班。但你对我的话左耳进右耳出。所以我只好解雇你了。
