中文中常会用“一只耳朵进，一只耳朵出”来表示某些话听到了，但根本没有放在心上。而在英语中，也有近乎相同的表达。通常会说: Something goes in one ear and out the other.

Examples:

The teacher felt that everything she told her students was in one ear and out the other. 老师感受到教给学生的东西，都会左耳朵进，右耳朵出。

How many times have I told you to get to work on time. But my words just go in one ear and out the other. 多少次我告诉你上班要准时。但是这些话总是一耳朵进，一耳朵出，毫不起效。
