高中英语状语从句讲解及练习
状语从句
状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。
一、时间状语从句
引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time等。时间状语从句中一般用一般现在时或一般过去时。
1．When , while, as都可解释为“当```的时候”但侧重点有所不同。
1)W hen
Eg: When I arrived home , I had a little rest.
注意点：
when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。
Eg: When (she was) walking along the street, she met her class teacher.
2)A s
As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”
Eg: He sang as he danced.(一面```一面) You will grow wiser as you grow older.(随着)
3)W hile表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。
Eg: While we were working, they were having a rest.
While (they were) having a discussion, they got very confused.
注意点：
while 有对比的含义，解释为“然而”。eg: I prefer black tee, while he likes coffee.
2．until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
肯定句：I waited until midnight.
否定句：I did not leave until midnight.
注意点：
1）not until…在句首，主句用倒装
eg: Not until you had explained how did
I manage to do it.
2) It is not until…that…引导的强调句
It was not until it was dark that he came back.
3. the minute, the moment, each time都可表示“一```就```”
eg: The worker recognized the type of the machine the moment he saw it.
注意点：
the minute, the moment, each ( every, next, the first) time作连词不和when 连用。4．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```”
eg: I had hardly/scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
It began to rain as soon as I got home.
注意点：Hardly/scarcely…when, no sooner…than位于句首，主句用倒装eg: Had I hardly/scarcely got home when it began to rain.
No sooner had I got home than it began to rain.
二条件状语从句
条件状语从句分为两大类：真实条件句和虚拟条件句。引导条件状语从句的连词有：if, even if/though, unless/ if …not, as long as/ so long as, as far as/so far as, provided/providing (that), on condition that 等。条件状语从句中如果主句是将来时，条件状语从句用一般现在时。1.unless 和if…not
unless 相当于if…not
eg: You will fail unless you study hard.
You will not fail if you study hard.
注意点：
在虚拟条件句中可用if…not，但不能用unless
eg: If she were not too silly,she would
understand.
2．引导条件状语从句的其它连词：Eg: You may go there ,as long as you keep quite.
Eg: I shall give you the book on condition that you return it tomorrow.
Eg: I will go provided that you go too.
三让步状语从句
引导让步状语从句的连词有：though, although, even if/ though, however, no matter how, no matter what, no matter who 等。
1．though, although不可与but连用，但可以和yet , still连用.
Eg: Though/Although it is raining ,they are still running outside.
注意点：
1）though可引导倒装(although不引导倒装)，结构为：
强调对象+as/though+主语+其它成分，强调对象可为表语（名词、形容词）或状语（副词），表语为名词时，前面不用
冠词。
Child as/ though he was, he knew what was the right thing to do.
Tired as he is, he goes on with his work. 2）despite 和in spite of 也有让步意义，后接名词或动词，而though, although是连词，后接从句。
Eg: Despite /In spite of wanting to see him again, she refused to reply to his letter.
Though/although she wanted to see him again, she refused to reply to his letter.
2. “no matter+疑问词”或“疑问词+后缀ever”
eg: No matter what happened, he would not mind.
Whatever happened, he would not mind.
注意点：no matter+疑问词不能引导名词性从句
3.even if/ though表示“即使”
eg: He doesn’t want to marry her even if/ though he loves her very much.
四原因状语从句
引导原因状语从句的连词有：because, since, as , now that ,considering that, for the reason that , due to the fact that,owing to the fact that等
1．because
because语气最强，通常用于回答why 提出的问题
注意点：
在it was…that…的强调结构中，强调原因状语从句可用because引导，不用since,as, for引导。
Eg: It is because she is too inexperienced that she does not know how to deal with the situation.
2. since和as
since的语气比because 弱，比as强，表示间接的，已知的原因，自然的结果，表示“既然，由于”。
Eg: As/ Since you are not very well, you had better have a rest.
3．for
当for表示原因关系时，for分句是对第一分句内容的推断或猜测。
Eg: It must have rained last night, for the ground is wet now.
五目的状语从句
引导目的状语从句的连词有：so that, in order that, lest, in case, for fear that等。Eg: You must speak louder so that/in order that you can be heard by all.
He wrote the name down for fear that he should forget it.
Better take more clothes in case the weather is cold.
注意点：lest, in case, for fear that所引导的状语从句中，动词可以用虚拟语气，形式为should+动词原形，也可不用虚拟语气，用动词的一般现在时或一般过去时。
Eg: You had better leave the key at home in case one of us should think of/thinks of coming back.
六结果状语从句
引导结果状语从句的连词有：so that, so…that, such…that等
eg: He is so young that he can not go to school.
He is such a young boy that he can not go to school.
1．常用句型：
so+形容词/副词+that从句
so+形容词+a/an+单数可数名词+that从句
such +a/an+形容词+单数可数名词+that 从句
such +形容词+复数可数名词/不可数名词+that从句
2．so和such的搭配规律
such修饰名词或名词词组，so修饰形容词或副词,so还可接many, few, much, little等。
Eg: so foolish such a fool so nice a flower such a nice flower
so many/few flowers such nice
flowers
so much/little money such rapid progress
so many people such a lot of people
七比较状语从句
引导比较状语从句的连词有：as…as, than, not so…as, the more…the more等
如：
He speaks English as fluently as his brother (does)
I can’t jump so /as high as he (does) There are more workers in this factory than in the one next to it .
The more you read, the more interesting , you will find the novel is .
连接词than 可作为关系代词用。如：
He wrote more than was necessary
Don’t carry more mo ney than is needed
八地点状语从句
引导地点状语从句的连词有:where, wherever以及where构成的复合词等eg: She found her calculator where she lost it.
Wherever I am, I will miss you.
注意点：
eg: I happened to see your dictionary lie where I used it last time.（地点状语从句）
I happened to see your dictionary lie in the lab where I used it last time.（定语从句）
九方式状语从句
引导方式状语从句的连接词有as, just as, as if / though（一般用虚拟语气，也有用直陈语气的）等。
EG：Just do as you are told.
The workers went on working as if nothing had happened.
He talked to the girl as though he had
fallen in love with her.
在just as ---, so --- 结构中，as 带有比喻含义。意为“正如”，多用于正式文体。
EG：Just as some people like sports, so some people like music.
the way 也可引导方式状语从句。EG：you should operate the machine the way I do .

(完整word版)高中英语状语从句用法详细解析
高中英语状语从句用法详细解析 一、定义： 在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。 二、分类 根据意义上的不同，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句 三、时间状语从句 （一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once. （二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。

高中英语语法---条件状语从句讲解
条件状语从句 概念定义 由引导词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。（注意：在含有条件状语从句的复合句中，表示将来时态，主句是一般将来时态,祈使句或情态动词，从句要用现在时态,[主将从现原则]（主将从现，将并非指将来时，还指表示将来含义的，跟着if后的那句话是从句。） 类型 条件状语从句 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如： 1） If you ask him,he will help you. 如果你请他帮忙，他会帮你的。 2） If you fail in the exam,you will let him down. 如果你考试不及格，你会让他失望的 if引导的条件状语从句既可以将从句放前面也可以将从句放后面 （如果天下雨，我们就不玩了）If it rains,we will stop playing.‘ 转为We will stop playing if it rains. if引导的条件状语从句
另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设，从句多用一般过去时或过去完成时。如：If I were you,I would invite him to the party.如果我是你，我会邀请他参加聚会。I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车，我会到的早一点儿。 那么，除了if之外，是否还有其他连词也可以引导条件状语从句呢?回答是肯定的，不仅有，还有很多。这些词由于出现的频率较小，且用法较复杂一些，所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非，若不，除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身，你就不能及时赶到那儿。 Unless it rains,the game will be played.除非下雨，比赛将照常进行。 2、on condition(that)...在……条件下，如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相，条件是你答应保密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果，假如 supposing引导的条件从句表示一种假设条件。 Supposing it rains,shall we continue the sports meeting?倘若下雨，我们的运动会还要继续举行吗? Supposing anything should go wrong,what would you do then?假如出了什么问题，你准备怎么对付?
