when, befre, by the time
过去某一时刻或动作之前已经发生或完成的动作。
by the time 的用法
by the time 意为“到……时候(为止)”, 是一个介词短语, 在句中常起到连词的作用, 引导时间状语从句。1.如果从句中的谓语动词是一般过去时, 那么主句的谓语动词通常用过去完成时, 表示“截止到从句动作发生时, 主句动作已经完成, 即过去的过去”。
例：By the time yu came back, I had finished this bk. 你回来时我已经把这本书看完了。 （从句谓语动词came back 为一般过去 时, 所以主句动作用过去完成时had finished, 表示过去的过去。）
2. 如果从句中的谓语动词为一般现在时或现在完成时, 那么主句中的谓语动词常用将来完成时, 表示“截止到将来的某一时刻为止, 主句动作将已完成”。例：By the time I get hme, they will have left. 我到家时他们将已经离开。 By the time I graduate next year, I will have lived here fr five years. 到明年毕 业时, 我将已经在这待了五年了。
现在完成时与过去完成时的区别：现在完成时表示的动作发生在说话之前某个没有明确说出的过去时间，侧重过去发生的动作对现在产生的影响或造成的结果，与现在有关；过去完成时的动作发生在“过去的过去”，它是一个相对的时态，不能离开过去的时间而独立存在。
