句常考知识点：
1.although 、though、as用法；
2.wh-ever 和no matter wh-区别
3.when 和while区别
although /though（尽管，虽然）
(1)一般可以替换，不能与but 连用，但可以与yet, still,
nevertheless 连用。
e.g.
Although /though it was raining hard ,yet they went on
playing football.
(2)though 还可用作副词，置于句尾。
e.g.
He said he would come ,he didn't ,though.
as /though (倒装)
as /though位于句首，从句中的表语、状语、动词原形提前。
若表语是单数名词，前置时要省略冠词。
e.g.
Child as/though he is ,he can swim well.
Much as/though I like it , I won't buy it .
wh-ever和no matter wh-
1.wh-ever 和no matter wh-都可以引导状语从句
e.g. No matter when he comes back, he should be
invited to the party.
=Whenever he comes back, he should be invited to
the party.
2.wh-ever 还可以引导名词性从句,no matter wh-不
可以。
e.g. You can take whatever you like.
when,while
when,while 也可以做从属连词，让步状语从句，引导相当于
although。
e.g.
Suddenly,she stopped when she should have continued.
While I admit that there are problems ,I can't agree with you .

when :后面接延续性或短暂性动词，表示主从句动作同时发
生或从句动作先于主句动作。
e.g. When the film ended ,the people went back .
while:后面接延续性动词，表对比。
e.g. Please don't talk so cloud while others are working .
as:侧重主从句动作交替或同时发生，译为“一边...一边”
或“随着”。
e.g. It't getting warmer and warmer as time goes by .
“一...就...”
1.as soon as、immediately、directly、the moment /minute：
通常表示主句动作紧跟从句动作发生。
e.g.
As soon as I got home ,the telephone rang .
The boy burst into tears immediately he saw his mother.
The moment I heard the voice ,I knew father was coming .
“一...就...”
2.No sooner ...than,harderly ...when ：在时态上主句的谓语动
词用had done 形式,从句的谓语动词用did形式。
e.g. He had no sooner arrived home than he was asked to start
on aother journey .
3.如果no sooner 位于句首，其后谓语部分要倒装。
e.g. No sooner had he arrived home than he was asked to start
on aother journey .
hardly ...when的用法同理。
till ,untill,not...until
（1）till ,until 表示某一动作持续到某时间点的才停止，所以
主句的谓语动词必须是持续性动词。
e.g. He remained there until/till she arrived .
（2）not...till/until 主句的谓语动词为点动词，译为“直到...
才”
e.g. He didn't go to bed till /untill she returned .
（3）Not until 位于句首，主句谓语动词要倒装。
e.g. Not until she returned did he go to bed .
before
（1）表示“还未/来得及...就，...才...”
e.g. We hadn't ran a mile before he felt tired .
（2）It will be +段时间+before ...译为“还要多久才...”
e.g. It may be many years before we meet again .
（3）It won't be +段时间+before ...译为“过不了多久就...”
e.g. It won't be long before we meet again.
since
（1）时态搭配
since后从句谓语动词用did ,主句谓语动词根据句意用
do/have(has)done/have(has)been doing.
e.g.
I have written home four times since I came here .
（2）It is +段时间+since 从句...
句意根据从句后的谓语动词是否可以延续来判断。
e.g.
It is three years since I began to smoke.(短暂性动词—表示肯定
)
It is three years since I smoked.（延续性动词—表示否定）
