状语从句     

【要点点拨】

近几年高考对状语从句的考查主要体现在以下几个方面:

【考点1】when,while与as的用法

      均可表示“当……的时候”,但有区别:

when:既可接表示动作性或短暂性的动词,也可接表示状态的动词,不强调主从句谓语动作同时发生。有时还有“这时”的意思。

while:常接持续性的动词,强调主从句谓语动作同时发生,常用进行时。有时还有对比意义,意为“然而”。

as:强调同时发生或伴随进行。常用一般现在时或过去时,意为“一边……一边……”。有时还有“随着”含义。

① I do every single bit of housework ________ my husband Bob just does the dishes now and then.

     A. since                   B. while               C. when               D. as             (2004广西)

【考点2】“一……就……”几种表达法

once,as soon as,the moment / minute,immediately / directly / instantly引导的从句常用一般现在时或过去时。

hardly / scarcely … when…和no sooner … than …结构中,前句常用过去完成式(常用部分倒装形式),后句用过去式。

On doing sth.,each / every / the first / the last + time 后也可直接接从句,一起作时间状语。

② —— Did you remember to give Mary the money you owed her?

   —— Yes. I gave it to her _____ I saw her.                              (2004北京西城)

     A. while                  B. the moment           C. suddenly         D. once

【考点3】because,as,since与for的用法比较

   because:表示直接的原因或理由。用于回答Why的问题。because与so不能同时并列使用。

   since:表示对方已知的,无须加以说明的既成事实的理由。译为“既然”。

   as:表示十分明显的原因,一般说明因果关系。

   for:常出现在并列句中,不说明主句行为发生的直接原因,只提供一些补充说明,且不可位于句首。

③ _______ you are leaving tomorrow, we can eat dinner together tonight.     (2004江苏启东)

    A. For                B. Since               C. When                     D. while

【考点4】no matter后可接who,whom,whose,which,what,when,where,how,whether

引导的让步主语从句可用whoever,whomever,whenever,whichever,whatever,wherever,

however替换,但在ever引导其它从句时不可用no matter引导。

【考点6】引导让步主语从句应注意等几个问题

  1.由although / though , even if / though引导

       注意although / though 引导从句时,主句不能用but,但可用yet或still。

2.由whether … or (not) 引导

4.though用作副词,可位于句末,并用逗号分开。

    A. whenever              B. whether                 C. whatever         D. no matter

【考点7】before用法

   注意before在下列句型中的使用

    It will be + 一段时间 + before + 从句

【考点10】状语从句的省略用法

1.当when,while,if,unless引导状语从句时,如果主从句的主语一致,且谓语部分由be动词构成(或者从句中有it is…)时,可省略主语和be动词(或省略it is)。

2.在虚拟条件状语从句中,如果从句中有had,should,were时,可省略if,用“had,should,were + 主语”形式。
