一. 时间状语从句　　

1. when引导的时间状语从句，常译为“当……的时候”，when的从句可以用延续性动词，也可以用点动词。　　

eg.

Someone knocked at the door when I was sleeping. 当我正在睡觉时，有人敲门。　　

I will visit my good friend when I have time. 当我有空儿时，我将去看望我的好友。　　

I worked for a foreign company when I was in 　　Shanghai　　. 当我在上海时，我为一家外国企业工作。　　

注：when也可以作并列连词，表示一个动词正在进行的时候，突然间发生了另外一件事。　　

eg.　　

I was fishing by the river, when someone called for help. 　　

我正在河边钓鱼，就在那时有人求救。　　

We were working in the chemistry lab, when the lights went out. 　　

我们正在化学实验室工作，突然灯都熄灭了。　　

2. while引导的时间状语从句，常译为“与……同时，在……期间”，while的从句中常用延续性动词或表示状态的词。　　

eg. 　　

They rushed in while we were discussing problems. 　　

当我们正在讨论问题时，他们冲了进来。　　

Father was cleaning the car while I was playing computer games. 　　

当我正在打电子游戏时，爸爸正在清洗汽车。　　

注：while也可以作并列连词，表转折的关系，相当于but，译为“然而”。　　

eg.　　

I like listening to music, while my brother likes doing sports.

3. as引导的时间状语从句，常译为“当……的时候，一边……一边”as的从句中可使用延续性动词，也可使用点动词。

随着时间的推移，我们对自己周围的事物有了更好的理解。　　

4. before和after引导的时间状语从句，before强调主句的动作发生在从句的动作之前，而after强调主句的动作发生在从句的动作之后。　　

eg.　　

He had been a cook before he went to college. 他上大学前曾当过厨师。　　

He called me after he had finished his work. 他在工作完之后给我打了个电话。　　

注：若主句和从句两个动作发生的先后顺序十分接近，那么也可以不用完成时态，例如上面的第二句可改成：He called me after he finished his work. 　　

5. as soon as引导的时间状语从句，译为“一……就……”。　　

eg.　　

He will go to see you as soon as she gets here. 他一到这里就会去看你。

eg.

We haven’t seen each other since we parted. 我们自从分手以后一直没见过面。　　

注：常用句型：It is +时间段+since从句   译为：自从……有多长时间了。　　

eg.

自从她大学毕业已有六年的时间了。　　

7. till和until引导的时间状语从句，译为“直到……为止”，not … till / until引导的时间状语从句，译为“直到……才”。前者强调主句动作的结束，用延续性动词，后者强调主句动作的开始，用点动词。

We won’t start our discussion until / till he comes. 　　

我们要等到他来了，再开始我们的讨论。　　

二、让步状语从句:　　

though, although　　

　注意： 当有though, although时，后面的从句不能有but，但是 though 和yet可连用

　He is very old, but he still works very hard.　　　

　虽然他很老，但仍然努力地工作。

　伤口虽愈合，但伤疤留下了。 （谚语）　　

　 　

典型例题　　

1） ___she is young, she knows quite a lot.　 　　

A. When　B. However　 C. Although　 D. Unless　　

答案：C。意为虽然她很年轻，却知道许多。　　

　 　

2)　as, though 引导的倒装句　　

　 as / though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）。　　

　　Child as /though he was, he knew what was the right thing to do.　　

　= Though he was a small child, he knew what was the right thing to do.　　

　 　

注意： a.　句首名词不能带任何冠词。　　

　　　　b.　句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。　　

　　 Try hard as he will, he never seems able to do the work satisfactorily.　　

　 = Though he tries hard, he never seems…　　

　虽然他尽了努力，但他的工作总做的不尽人意。　　

　 　

3)　ever if, even though.　即使

4) whether…or-　 不管……都　　

　　 Whether you believe it or not, it is true.　　

　 　

5)　"no matter +疑问词" 或"疑问词+后缀ever" 　　

　　 No matter what happened, he would not mind.　　

　　 Whatever happened, he would not mind.　　

　 替换：no matter what = whatever　　

　　　　 no matter who = whoever　　

　　　　 no matter when = whenever　　

　　　　 no matter where = wherever　　

　　　　 no matter which = whichever　　

　　　　 no matter how = however　　

　 注意：no matter 不能引导主语从句和宾语从句。

　（对）Whatever you say is of no use now.　　

　　　 你现在说什么也没用了。(Whatever you say是主语从句)
