BEFORE(在我意识到事情真相之前过了一段时间)考擦状语从句
1.when"当……时",引导时间状语从句时,从句用于表示主句动作发生的特定时间.例如:
The days get longer when spring comes.春天到来时,白天变得更长了.
2.before"在……之前",引导时间状语从句时,表示主句动作发生在从句动作之前.例如:
Close the door before you leave the room.离开房间前关上门.
3.after"在……之后",引导时间状语从句时,表示主句的动作发生在从句的动作之后.例如:
I went to bed after I finished my homework.做完作业后我就去睡觉了.
4.until、till"直到",引导时间状语从句.当主句谓语动词是延续性动词时,主句常用肯定形式;当主句谓语动词是非延续性动词时,主句要用否定形式,即"not ...until / till ..."意为"直到……才……".例如:
I'll wait here until / till he comes back.我将在这里等着,直到他回来.
You can't go home until / till you finish your work.直到你完成你的工作,你才能回家.
