【—辅导之状语从句】下面是对状语从句语法的讲解,同学们认真学习。
状语从句:
此处所说的状语从句用法仅包括条件(if和unless引导)状语从句和时间(when等引导,见下文)状语从句。状语从句需注意以下问题:
1主句若是一般将来时、祈使句或含不表过去的情态动词等,则if(如果), unless(除非),when(当…的时候), as soon as(一…就…),before, after, until, till, as(当…的时候)所引导的状语从句用一般现在时。
You may take a rest when you finish doing your work. (主句有情态动词)
Could you look after my son after I leave home?
(情态动词could是为了让语气委婉,并不指过去时,从句仍用一般现在时)
I will go out as soon as it stops raining this afternoon. (主句是将来时)
Wait for your brother at the bus station until he arrives. (主句是祈使句)
2而主句若是一般过去时,从句也要用表过去时的适当时态,如:
I would give the money to the charity if I had a million dollars.
When he got to the park, his classmates had left.
My son ran towards me as soon as he saw me on the street.
通过上面的讲解,相信同学们对状语从句的可以很好的掌握了,希望同学们在考试中取得好成绩。
