【—輔導(dǎo)之狀語從句】下面是對(duì)狀語從句語法的講解，同學(xué)們認(rèn)真學(xué)習(xí)。

　　狀語從句：

　　此處所說的狀語從句用法僅包括條件(if和unless引導(dǎo))狀語從句和時(shí)間(when等引導(dǎo),見下文)狀語從句。狀語從句需注意以下問題：

　　1主句若是一般將來時(shí)、祈使句或含不表過去的情態(tài)動(dòng)詞等，則if(如果), unless(除非)，when(當(dāng)…的時(shí)候), as soon as(一…就…)，before, after, until, till, as(當(dāng)…的時(shí)候)所引導(dǎo)的狀語從句用一般現(xiàn)在時(shí)。

　　You may take a rest when you finish doing your work. （主句有情態(tài)動(dòng)詞）

　　Could you look after my son after I leave home?

　　（情態(tài)動(dòng)詞could是為了讓語氣委婉，并不指過去時(shí)，從句仍用一般現(xiàn)在時(shí)）

　　I will go out as soon as it stops raining this afternoon. （主句是將來時(shí)）

　　Wait for your brother at the bus station until he arrives. （主句是祈使句）

　　2而主句若是一般過去時(shí)，從句也要用表過去時(shí)的適當(dāng)時(shí)態(tài)，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.

　　通過上面的講解，相信同學(xué)們對(duì)狀語從句的可以很好的掌握了，希望同學(xué)們?cè)诳荚囍腥〉煤贸煽?jī)。
