地道表达

be out like a light

1. 解词释义

Like a light的意思与“灯”没有任何关系，其实际意思是“睡着”。而对话中在like a light前面有个副词out，即为：out like a light，其意思就带有“不省人事，昏睡，被击昏”的意思了。

2. 拓展例句

e.g. After the sustained effort of the day I lay down on the bed and went out like a light.

持续不断地苦干了一整天后，我一躺在床上就昏昏入睡了。

Ps：leave for something的意思是“离开呆在的地方去做某事”。例如：
