条件状语从句

条件状语从句分为真实条件句和虚拟条件句两种。假设的情况有可能发生的条件句叫真实条件句;若假设的情况完全是一种假设或发生的可能性不大的条件句叫非真实条件句。

引导条件状语从句的连词有:if,unless,so/as long as(只要),in case(万一……的话),on condition that(假如;在……条件下),suppose/s upposing(that)(假设),provided/providing

(that)(倘若;在……条件下),for fear (that)(以免,唯恐)等。

1.If you have finished your homework,you can go out and play.

___________________________________________________________________________

2.You’ll fail the exam _____________________________(除非你努力学习)。

【特别提示】条件状语从句中通常不用将来时态,要用一般现在时或现在完成时代替一般将来时,一般过去时或过去完成时代替过去将来时。

3.只要你不失去信心,你会成功的。

____________________________________________________________________________

4.___________(万一) anything important happens,please call me up.

5.如果我父母也被邀请的话,我会来。

___________________________________________________________________________

6.我会带着伞,以防下雨。

I will take an umbrella _______________________________.

让步状语从句

在句子中作让步状语的从句叫让步状语从句。让步状语从句可置于句首,句尾或剧中。

引导让步状语从句的连词主要有:although,though,as,even though,even if,whether,whatever,however,no matter+疑问词等。

They will stand by you even if you don’t succeed._____________________________________________ Though/Though he was worn out, (still) he kept on working.____________________________________ 无论发生了什么,他都不会介意的。____________________________, he would not mind.

无论有多晚,他都会回家。______________________________,he will go home.

【特别提示】

1.no matter what(who,which,when,etc.)与whatever(whoever,whichever,whenever,etc.)的区别:

当引导让步状语从句时,两者相同,可以互换,但当引导名词性从(主语从句,宾语从句,表语从句和同位语从句)时则只能用whatever(whoever,whichever,whenever,etc)。如: I want to marry the man I love, no matter who he may be.

= I want to marry the man I love, whoever he may be.(让步状语从句)

__________comes back first is supposed to win the prize.(主语从句)

I am ready to do whatever you want me to .(宾语从句)

____________________________you did, I will accept.为让步状语从句.

I will accept _____________.(无论你做什么)为宾语从句.

2. as 引导让步状语从句的用法

引导让步状语从句时,as意为“虽然,尽管”,通常从句要倒装,倒装的方法是将从句的表语或状语放在as之前.即:adj./adv./n.(不用冠词)/v.(原形)+as+主语+其他。

________________________(尽管外面正在下大雨), they started out very early.

虽然他很小,但是他知道的很多。____________________________________

她虽然是名工人,但是很努力工作。______________________________________

Try as he would, he could not lift the rock. _______________________________________

3. although和though不可与but连用,但可与yet,still或nevertheless连用。

Although it was raining hard,yet they went on playing football.尽管他看起来弱,但是很健康。
