【—輔導(dǎo)之狀語(yǔ)從句】下面是對(duì)狀語(yǔ)從句語(yǔ)法的講解,同學(xué)們認(rèn)真學(xué)習(xí)。
狀語(yǔ)從句:
此處所說(shuō)的狀語(yǔ)從句用法僅包括條件(if和unless引導(dǎo))狀語(yǔ)從句和時(shí)間(when等引導(dǎo),見(jiàn)下文)狀語(yǔ)從句。狀語(yǔ)從句需注意以下問(wèn)題:
1主句若是一般將來(lái)時(shí)、祈使句或含不表過(guò)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(yǔ)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?
。ㄇ閼B(tài)動(dòng)詞could是為了讓語(yǔ)氣委婉,并不指過(guò)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(lái)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(guò)去時(shí),從句也要用表過(guò)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(guò)上面的講解,相信同學(xué)們對(duì)狀語(yǔ)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)。
