狀語從句
所謂狀語從句,是指用來說明主句行為發(fā)生的時間、原因、條件、地點(diǎn)、目的、結(jié)果及方式等。
1) 時間狀語從句:記住以下連接詞的意思和重點(diǎn):
when / while / as
注意:while除了做時間狀語的連接詞外,還解釋為雖然,而.
例如:He is very diligent, while she is very lazy.
before 在之前
until / not until注意:not until放在句首時,往往要求倒裝
as soon as / once
immediately / instantly / directly 原本是副詞,這里作連接詞,表示一就,
例如: I knew I had made a mistake directly I had done it.
the moment / each time / every time / next time / the first time / the instant / the year原本是名詞或副詞,這里作連接詞用。
hardly when / no soonerthan一就
注意:這是時間狀語考試的重點(diǎn)句型,一是不要把兩個句型中的when和than的搭配搞錯了,二是要用倒裝語序。
例如:
Hardly had I sat down when the telephone rang.
重點(diǎn):在時間狀語中,用一般時代替將來時。
例如:
Well start as soon as the leader ______.
A.comes B.is comingC.will come D.came
根據(jù)英語時態(tài)一致性原則,主句與從句的時態(tài)應(yīng)一致,答案似乎應(yīng)該是B或C,但是正確答案是A,因?yàn)樵跁r間狀語中,用一般時代替將來時。將上句改為過去時,道理也一樣:
He said we would start as soon as the leader _____.
A.came B.was coming C.would come D.comes
答案應(yīng)為A。
