6月英語四級語法狀語從句匯總

  2017年6月英語四級語法狀語從句匯總

  1) 時間狀語從句

  時間狀語從句主要由以下連詞引導(dǎo):when, whenever, as, while, since, until, till, before, after, as soon as, once, hardly (scarcely) …when, no sooner …than。

  I will discuss the matter with you when we meet tomorrow.

  時間狀語從句還可由某些可充當(dāng)連詞的名詞(the moment, the instant, every time,等)和副詞(instantly, directly等)引導(dǎo):

  I will tell you the news the instant I know.

  Note:

 、賐efore除了可表示“在…之前”外,還可用來強調(diào)主句所表達的時間、距離很長或花費的力量相比較大,可譯為“…才”。(“not …before”可用來強調(diào)主句所表達的時間、距離很短或花費的力量相比較小,可譯為“…就”)。

  It was a long time before I got to sleep again.

 、谌绻挥趙hen引導(dǎo)的分句之前的主句使用過去進行時、過去完成時或“was/were about to, was/were on the point of”等結(jié)構(gòu)時,when表示突然發(fā)生某事,可譯為“正在…突然”或“剛…就”等。這時,不能夠用as或while來代替when。

  I was walking on the street when I ran into my old friend John.

  2) 條件狀語從句

  條件狀語從句主要由以下連詞引導(dǎo):if, unless, providing/provided (that), suppose/supposing (that), on condition (that), as/so long as, in case等。

  So long as you work hard, you will surely achieve good results in examinations.

  3) 讓步狀語從句

  讓步狀語從句主要由以下連詞引導(dǎo):though, although, even if, even though, whatever, however, whoever, wherever, no matter how/ what/ where/ when等。以下介紹幾種較特殊的讓步狀語從句。

  (1)while引導(dǎo)的讓步狀語從句多放在句首,while相當(dāng)于although,表示“盡管”,“雖然”。

  While I admit I did it, I didn’t intend to.

  (2)短語“even now/then/so”相當(dāng)于“though it is/was true”,表示“盡管如此”,“盡管這樣”。

  The fire was out, but even so, the smell of smoke was strong.

  (3) as引導(dǎo)的讓步狀語從句要倒裝。

  Child as he was, he could speak four languages.

  4) 比較狀語從句

  比較狀語從句主要由以下連詞引導(dǎo):(not) as …as, (not) the same as, (not) such …as, not so …as, than, the + 比較級…, the +比較級…等。

  We have had a lot more rainfall this year than we had last year.
