Unit13 状语从句
一、考点聚焦%
1、时间状语从句
（1）as、when、while用法一览表。
类别 作 用 例 句
as as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。 She came up as I was cooking.(同时)
The runners started as the gun went off.(几乎同时)
when (at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。 It was raining when we arrived.(指时间点)
When we were at school, we went to the library every day.(在一段时间内)
while while意思是“当……的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在when表示a period of time时，两者可以互换。 Please don’t talk so loud while others are working.
He fell asleep while/when reading. Strike while the iron is hot.(用as或when不可，这里的while意思是“趁……”)
（2）引导时间状语从句的连接词除上述外还有：
①till, not … until …, until, before, since
Don’t get off the bus until it has stopped.
He waited for his father until(till)it was twelve o’clock.
It will be five years before he returns from England.
②hardly / scarcely … when, no sooner … than, as soon as once
表示“一……就”
As soon as I have finished it , I’ll give yu a call.
Once you show any fear, he will attack you.
We had hardly got / Hardly had we got into the country when it
began to rain.
No sooner had he arrived / He had no sooner arrived than she started complaining.
③directly, immediately, the moment, the minute that… 一……就
He made for the door directly he heard the knock.
④each time, every time, by the time
Each time he came to my city, he would call on me.
注意：表示未来情况，主句用将来时，从句用现在时。
2、让步状语从句
（1）although与though可以引导让步状语从句，不能与but连用，但可以与yet连用。
Although they are poor,(yet)they are warm-hearted.
（2）even if或even though引导让步状语从句，表示“即使”，“纵然”，用来使人注意下文所强调内容的性质。
I’ll get there even if(though)I have to sell my house to get enough money to go by air.
（3）no matter后接上who、what、where、how等疑问词，也可以在这类疑问词后面加上ever构成whoever、whatever、wherever、however等。
Don’t trust him, no matter what / whatever he says.
Whoever breaks the law will be published.
No matter how hard the work is, you’d better try to do it well.
（4）as也可以引导让步状语从句。要用倒装。
Child as(though)he is, he knows a lot.
Much as I like it, I won’t buy.
Try as he would, he couldn’t lift the heavy box.
3、原因状语从句：because, for, as, since, now that
（1）表示不知道的原因时用because,即说话人认为听话人不知道，因此because从句是全句最重要的部分，通常它被置于主句之后。
You want to know why I’m leaving? I’m leaving because I’m full.
for虽然表示不知道的原因，但其语气较because要弱得多，是可说可不说的话，它只能置于主句之后，这时，for是并列连词。如果不是因果关系，而是对前面主句的内容加以解释或推断时，只能用for。如：It’s morning now, for the birds are singing.（很显然，鸟叫不可能是“现在已是早上”的原因。）
（2）表示已经知道的原因时用as或since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since要比as正式一些，它们通常被置于语句之前，但有时却相反。
Seeing all of the children already seated, he said,“Since everyone is here, let’s start.”
(3)下列情况下只能使用because:
①在回答why的问句时；
②在用于强调句型时；
③被not所否定时。
4、地点状语从句：where, wherever
Make a mark wherever you have any questions.
We will go where the Party directs us.
5、目的状语从句：that, so that, in order that
注意：目的状语从句的谓语动词常与情态动词连用，否则可能是结果状语从句。不可置于句首。
6、结果状语从句：that, so that, so … that, such … that …
注意：so + 形容词/副词 + that从句；such + 名词 + that从句。
7、方式状语从句：as, as if(though)
I’ll do as I am told to.
It looks as if it is going to rain.
8、比较状语从句：than, as
9、条件状语从句：if, unless, so (as) long as, in case, once, a far as, on condition that.
注意if与unless的区别：不能用and连接两个unless从句，即不能有… unless …,and unless … 。但if … not and if … not却不受此限。
You won’t lose your weight unless you eat less and unless you exercise more.(×)
但可以说 … unless you eat less and exercise more.
10、注意状语从句中从句的省略现象
（1）连接词 + 过去分词
Don’t speak until spoken to.
Pressure can be incrased when needed.
Unless repaired, the washing machine is no use.
（2）连词 + 现在分词
Look out while crossing the street.
（3）连词 + 形容词/其他
常见的有it necessary、if possible、when necessary、if any等。
二、精典名题导解'
选择填空
1. I don’t think I’ll need any money but I’ll bring some ____________.
(NMET )
A.as last B.in case C.once again D.in time
解析：答案为B。句意为“带些钱以防万一”，只能选择in case。引导的条件状语从句，后面省略了I should need it。
2. The WTO can’t live up to its name _________ it doesn’t include a country that is home to one fifth of mankind.（NMET 2000）
A.as long as B.while C.if D.even though
解析：答案为C。本题考查状语从句的用法。句意为“假如世贸组织不包括占世界人口五分之一的中国的话，那它就名不副实”。as long as语气过于强烈，while和even though不符合句意。
3、Someone called me up in the middle of the night, but they hung up_________I could answer the phone.(NMET 2000)
A.as B.since C.before D.until
解析：答案为C。题意为：半夜里有人打来电话，我没来得及就挂了。but暗示在接话前就挂了。
1、状语从句即指在主从复合句中用作状语的从句。状语从句根据其用途可分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句、方式状语从句等。
2、时间状语从句：是由when、as、while、after、before、since、until、as soon as等从属连词引导的状语从句。时间状语从句中的谓语动词不能用一般将来时，只能用一般现在时表示将来发生的`动作或存在的状态。
3、原因状语从句：because、since、as和for都表示原因。because语势最强，回答why提出的问题，用来说明人所不知的原因。当能够很明显的看出原因或人们已知原因，就用as或since。由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
4、目的状语从句：表示目的状语的从句可以由in order that、so that等词引导。
5、结果状语从句：结果状语从句常由so...that或such...that引导，要掌握和区分这两个句型，首先要了解so和such后面分别跟什么词。such是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。so还可与表示数量的形容词many、few、much、little连用，形成固定搭配。
6、让步状语从句：是由though、although引导的状语从句。
1.引导时间状语从句的引导词有：
①表示某个时刻发生的动作：when、while、as、once
②表示某个时刻之前发生的动作：before、until
③表示某个时刻之后发生的动作：after、since
2. when引导从句时，主从句的动作有先有后，也可以同时进行，从句的动作可以是持续性的，也可以是短暂的。
eg. When I go to the cinema, the movie had already started. （主先从后）（短暂性）
When I watched movie, I used to eat ice cream. (同时) （持续性）
When the movie ended, the people went back. （从先主后）
3. while侧重主从句动作的`对比，且从句的动词必须是持续性的。
eg. While we were chatting she was reading comic．
4. as引导从句时侧重主从句动作同时或几乎同时进行，从句的动作可以是持续性的，也可以是短暂的。
eg. Sometimes I watch TV as I am having breakfast．
5. 关于when的固定搭配：
①…was/were doing…when…（正在做…突然）
②…was/were about to do…when…（刚要做…突然）
③…was/were on the point of doing…when…(刚要做…突然)
④…had just done…when….(刚一…就)
⑤Hardly/Scarcely had…done…when…(刚一…就)
引导的时间状语从句的主从复合句中，动作发生在先的用过去完成时，在后的`用过去时。表示前面的叙述所没有提到过的信息。它总是对所描述的事件予以引人注目的强调，意为“这时；突然”；当位于句末的分句具有引种用法时，大致有以下三种情况：
A. when 分句前面的分句使用过去进行时。如：
He was still smiling when the door opened and his wife came in. 他正笑着的时候，门突然开了，他妻子走了进来。
B. when 分句前面的分句使用 was （were） about to， was （were） on the point 等。如：
We were about to start when it began to rain. 我们刚要出发就开始下雨了。
C. when 分句之前的分句用过去完成时，其中 sb had hardly / scarcely /barely … when 已成为固定词组。如：
(1) We had hardly fallen asleep when the bell rang. 我们刚刚入睡，铃声就响了起来。
(2) He had scarcely arrived when he had to leave again. 他刚刚到达就又要离开了。
（2）

连接词：
in order that; so that; that; in case (以免)； for fear that (唯恐)；…
