條件狀語從句
連詞有:if, unless, as long as
(1) if引導(dǎo)的條件狀語從句 翻譯為:"如果", 時(shí)態(tài)遵循主將從現(xiàn),可以與祈使句進(jìn)行轉(zhuǎn)換,如:
If he said that,he can't be telling the truth.
如果他說了那樣的話,他不可能是說實(shí)話。
You ____________ (pass) the exam if you _________ (study) hard.
= _______________________________________________________________.
Hurry up, or you'll be late.
= _____________________________________________________.
(2) unless"除非"或"如果......不"引導(dǎo)的條件狀語從句
unless引導(dǎo)的是否定條件狀語從句,在意義上相當(dāng)于if...not,而且語氣較強(qiáng),一般不用于虛擬語氣。如:
You'll be late unless you hurry.
= _____________________________________________________.
你會(huì)遲到的,如果不趕快的話。
(3) as long as意為"只要;如果"。如:
__________________________________, we can play.
只要不下雨我們就能玩。
