状语从句语法讲解

第一篇：状语从句语法讲解

高中英语状语从句

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、时间状语从句主句是一般将来时,时间状语从句用一般现在时表将来；主句是过去将来时,从句用一般过去时表示过去将来时；主句是一般过去时,从句用一般过去时.记忆：“主将从现”

（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）、具体应用1）“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.记忆：While 后用进行时.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.2）When表示“就在„„的时候”, while意为反而,可是,表示转折.One evening Beethoven was walking in a street, when he suddenly stopped outside a little house.3）Whenever 无论什么时候,随时

1.Whenever someone throws in some rubbish, the truck produces a piece of music.每当有人扔进一些垃圾时,它（汽车）就放一段音乐.2.Whenever we’re in trouble, they will help us.3.I go to the theatre, whenever I am free.4.Come and see me whenever you want to.你随时来看我.4）till和until(表示“直到„„”)句首多用until

1、在肯定句中表示“直到„„为止”,主句谓语动词要用延续性动词.I was waiting until/till he arrived.2、在否定句中表示“直到„„才”主句谓语动词常用终止性动词,这时until和till常被before替换.I didn' t leave till/until she came back.5）since: 主句用完成时,从句用一般过去时,since引导的从句间或可用现在完成时.It is two years since I have studied English.1.We have known each other since we were children.2.We have been friends(ever since)since we met at school.3.It is „„(一段时间)+since+一般过去时态句子.It is two years since my sister married.„„(一段时间)have/has passed since +一般过去时态句子 Two sisters have/has passed since my sister married.Since+时间点

1.I have been at home since three o' clock this afternoon.2.Maria has been in China since two years ago.6）Every time, each time, next time Every time you get back at night, you drop your boots on the floor.Every time I catch cold, I have pain in my back.Next time I go there, I will visit them.7）once 一旦„就

Once you begin, you must go on.你一开了头,就应该继续下去.四、地点状语从句

地点状语从句用where, wherever引导

We should go where the people need us.我们应该去人民需要我们的地方.Where there is a will, there is a way.有志者,事竟成.Wherever they went, they received a worm welcome.无论他们走到哪儿都受到热烈欢迎.She follow him whose he goes.他无论到哪里她总跟着.五、原因状语从句

原因状语从句用because(因为),since(既然), as(由于)引导

1、字母由多到少,语气由强到弱.2、由why提问必须用because回答.Since, as不回答why的提问,而且从句一般放在句首,because一般放在主句之后.3、before of +名词

Because of the rain, we didn' t go to the park.4、because 和so不可连用,只能选其一.（另有although, but）Why didn' t he come to school? Because he was ill.Since I must die, I must.既然我一定要死,我一定这样做.Since a lot of people make mistakes in life, Mr Smith wanted to give John a Chance.5、for并列连词,不能放在句首,主要放在两个并列句之间.For所提供的理由为一个补充说明,而且前面常有逗号隔开.The days we short, for it is December now.六、目的状语从句 目的状语从句用so(常用于口语), that, so that, in order that引导

目的状语从句的谓语常含有may, might, can, could, should, would等情态动词.1.We'll sit never to the front so we can hear well.2.He studied hard so that he might succeed.3.I'll speak slowly so that you can take notes.4.They hurried to the station in order that they could catch the train.5.I took a taxi so that I could get there earlier.6.I’m going to the lecture early so that I may get a good seat.七、条件状语从句

条件状语从句由if, unless,(so)as long as(只需)引导

在条件状语从句中要用一般时表示将来时（与时间状语从句相同）

We will miss the train if you don' t hurry.He said we would miss the train if we didn't hurry.You will fail the exam unless you study hard.=(if you don’t study hard)He won’t come unless he is invited.=(if he isn't invited)Eat less food unless you want to become fatter.=(if you don’t want to become better)As long as you are not afraid of difficulties, you are sure to succeed.As long as you don't lose heart, you will succeed.八、结果状语从句

结果状语从句由such„that, so„.that, so that, that 引导 1.Such„ that 的常用句型

such +a/an +形容词+可数名词单数+that such +形容词+可数名词单数+that Such+形容词+可数名词复数（不可数名词）+that

注意so many(much, few, little)+名词,such a lot of(或lots of)+名词是惯用法,不可乱用.She is such a beautiful girl that we all like her.They were such beautiful flower that we bought home.It was such delicious food that they ate it up.2.so+形容词或副词+that so+形容词+a/an+可数名词单数+that He is so rich that he can buy lot of things for himself.He works so hard that he did everything well.It was so hot a day that we all went swimming.It was such a good day that we all went swimming.3.so that, that都可以引导结果状语从句

He didn't study hard,(so)that he failed the exam.4.Too„to, enough„to 可以引导结果状语从句与so„that 替换,so„that结构可以用too„to替换必须具备两个条件,一是主句和结果状语从句的主语必须一致,二是从句中的谓语部分必须含有can(could)not.She is young that she can’t go to school.She is too young to go to school.She isn't old enough to go to school.九、让步状语从句 although, though even though = even if, whether„or however = no matter how whatever = no matter what whoever = no matter who whenever = no matter when wherever = no matter where

*although和though都表示“虽然”只是although 更正式,多用于句首,而though用于句中,二者都可与yet, still连用,但不与but连用

Although/Though they are poor, they often help others.They are poor, but they often help others.Although he has failed many times, he doesn' t give up trying.Whatever/No matter what you say, I won' t believe you.No matter what you say, I don' t care.No matter who you are, you must obey the rules of our school.However hard he tried, he failed again.No matter what the weather is like, you can always find surfers out riding the waves.十、方式状语从句

方式状语从句由as(如同,按照),as if(though)引导

*as和like都有“像”的意思,as是连词,后面连接句子,like是介词后面可加名词、代词或名词性短语.I did the work as others did.相当于 I did like others.You must do as I do.as if(though)两者意义相同,从句谓语动词常用虚拟语气,但实现可能性较大,则用连接词.It seems as if/though it’s going to rain.They are talking as if/though they were old friends.She treats me as if I were her brother.When you are in home,do as the Romans do.例 You must do ______ I told you.A.after B.before C.where D.as(D)The students must do ______ the teacher told them.A.as B.before C.after D.if(A)

十一、比较状语从句

比较状语从句由as„as, not as(so)„as, than, the+比较级,the+比较级引导 He swims as well as you.(do)He doesn' t swim as well as you(do).He got here earlier than you.(did)The busier he is, the happier he feels.英语语法状语从句类型综述状语从句主要用来修饰主句或主句的谓语.一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式.尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难.状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点.现分别列举如下: 1．时间状语从句

第二篇：状语从句

Clauses of Condition, Concession and Contrast(条件、让步和对比从句)条件从句

由 if, unless, as(so)long as, provided / providing(that), suppose / supposing(that), in case等引导，如：

If he comes I'll tell you.You would have succeeded if you had tried harder.You will fail unless you work hard.(=You will fail if you don't work hard.)

Supposing / Suppose it rains, shall we have the match as scheduled?

In case you need anything else, please let me know.让步从句

由 although, though, even though, even if, whether...or, while, as, wh-words + ever(= no matter + wh-words)等从属连词引导，如：

He is quite modest though he is the best student in the class.The needle has the same mass whether it is hot or cold.Whichever(No matter which)plan you adopt, you will meet with difficulties.使用上述让步从句的某些从属连词时注意以下几点：

a.although(though)不可与连词 but 连用；

b.as 引导的从句意义和 though 相似，但表示的语气较强，并须将强调的词放在句首（但不用 although），如：

Simple as(though)the question may seem, it is not at all common in nature.c.however / no matter how 引导的从句中，however / no matter how 后须紧跟形容词或副词，如：

However / No matter how hard I tried, I couldn't remember all the questions.对比从句

表示两个人或两件事之间的对比，常用 while 或 whereas 引导，如：

He is idle, while his brother is diligent.Some people like fat meat, whereas others hate it.Clauses of Cause, Result and Purpose(原因、结果和目的从句)原因从句

主要由下列从属连词引导：

1． Because, as, since。其中 because 语气最强，表示直接、主要原因，通常引导的从句放在句尾，特别是回答 why 提出的问题只能用 because;as 和 since 表示明显的、已知的原因，since 比 as 正式，如：

They had to move because their building was to be pulled down.As Mary was the eldest, she looked after the others.Since they live near the sea, they often go sailing.2． now that, seeing(that), considering(that), in that。这些连词与 as, since 意思相近，通常用于书面语，并且它们兼有其它意义。now that 有“时间”含义，表示”既然”，说明一种新

情况；seeing(that)和 considering(that)有“条件”含义；in that 有”某一方面”含义，如：

常用 so that, in order(that), lest, for fear that 等连词引导，如：

I took a taxi so that I could be in time for the meeting.Come closer in order that you may see the blackboard better.so that 既可引导结果从句也可引导目的从句，但结果从句表示事实，通常不含情态动词；目的从句表示希望或想要实现的事实，通常含有情态动词，如：

He got up early so that he caught the train.（结果）

He got up early so that he could(might)catch the train.（目的）

Lest 和 for fear(that)含有否定意义，并且从句中动词须用 “动词原形”或 ”should + V.” 的虚拟语气，如：

He ran away lest he(should)be caught.(= He ran away in order that he would not be caught.)

I checked all the results time and again for fear that there should be any mistakes.(= I checked all the results time and again so that there wouldn't be any mistakes.)

Clauses of Manner and Comparison(方式和比较从句)方式从句

主要由 just as, as, as if, as though 等连词引导，如：

He doesn't speak the way as other people do.Our bodies are made up of millions of very small cells, just as a building is made of many stones or bricks.He speaks French as if(as though)he were a Frenchman.由 as if 或 as though 引导的从句通常用虚拟语气，但如果主句谓语是感官动词，并且所述情况实现可能性大，也可用陈述语气，如：

It looks as if the coming autumn harvest will be even better than the last one.比较从句

主要由 as...as, not so(as)...as, than 等连词引导，如：

This table is as wide as that one.Mary can not run so(as)fast as Tom.Silver conducts electricity better than other metals.Clauses of Proportion and Other Types(比例从句和其它从句)比例从句

由关联词 the...the...连接形容词或副词比较级构成，如：

如 as...so 和 what...that 引导的类比从句；so(as)far as 引导的范围从句；except that 引导的例外从句；rather / sooner than 和 would / had rather than 引导的择比从句等，如：

As the desert is like a sea, so is the camel like a ship.（沙漠似海，骆驼似舟。）

第三篇：初中状语从句讲解(时间、条件)

初中状语从句讲解

（一）一、什么是状语？

状语是在句中起重要辅助作用的一类句子成分，用于辅助说明

时间、地点、条件、原因、目的、结果、比较或让步（共八种功能）；句中，状语一般由副词或副词性的词组、句子充当（修饰动词、形容词，甚至句子和副词本身）。

标出下列句子的状语：

当将上述状语改为用连接词引导的句子时，全句就被称为状语从句。根据状语在句中的不同作用，又将其划分为时间、地点、条件、原因、目的、结果、比较或让步状语从句。

标出下列句子的状语：

1.Everything is OK as it was in the past.2.Loves miss each other when they are apart.3.Whenever I take exams, my mind blanks out.4.More and more college students, prefer to stay in dorm.二、初中状语从句重点：时间、条件状语从句。

（一）时间状语从句中的连接词：

When / while / asafter / before / since

As soon astill（不可用于句首）/ until By the time

（解释以上连接词的意思）

（二）时间状语从句中的时态：

1.You begin to know something when you think you know nothing.2.The president laughed as he spoke.3.By the end of this year, it will be four months since they joined the army.4.We went home after we had finished the work.5.My father had left for Canada before the letter arrived.时态的一致性：主句从句

现在时现在时/过去时将来时现在时/过去时过去时过去时

提问：为什么有些动作会用进行时/完成时表示？ 观察下列句子中的动词：

While my mom was reading the newspaper, I was watching TV.While my mom came in, I was watching TV.My mom was reading the newspaper while I came in.Jack left the office after he(had)finished the report.The writer had written many unknown books before he got famous overnight.（三）条件状语从句的连接词和时态：

Unlessif

时态一致性：主句从句将来时现在时（过去将来时过去时）翻译下列句子：

1.如果叫他的话他会帮你忙的。If you ask him, he will help you.2.除非下雨，比赛将照常进行。

The game will be held unless it rains.3.If I were you, I would not be so stupid.如果我是你，我不会那么笨的。

第四篇：状语从句讲解+练习(导学案)

状语从句

学习目标：

1.通过复习、记忆，记住状语从句的考点

2.通过练习、讲解，会用状语从句的知识解决问题。

由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。同时对方式状语从句也应引起重视。

（一）时间状语从句

表示时间的状语从句可由when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by the time, no sooner … than, hardly(scarcely)… when, every time等引导。

e.g.When I came into the office, the teachers were having a meeting.He started as soon as he received the news.Once you see him, you will never forget him.No sooner had I gone to bed than I went to sleep.（二）原因状语从句

原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。

e.g.He is disappointed because he didn't get the position.As it is raining, I will not go out.Now that you mention it, I do remember.（三）地点状语从句

引导地点状语从句的连词是where 和wherever等。e.g.Sit wherever you like.Make a mark where you have a question.（四）目的状语从句

引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。

e.g.Speak clearly, so that they may understand you.She has bought the book in order that she could follow the TV lessons.He left early in case he should miss the train.（五）结果状语从句

结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that（从句谓语一般没有情态动词）, so … that, such … that等引导。

e.g.She was ill, so that she didn’t attend the meeting.He was so excited that he could not say a word.She is such a good teacher that everyone admires her.（六）条件状语从句

条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话

者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so(as)long as, on condition that, so(as)far as, if only(= if)。注意：条件从句中的if 不能用whether替换。

e.g.If he is not in the office, he must be out for lunch.You may borrow the book so long as you keep it clean.So far as I know（据我所知）, he will be away for three months.You can go swimming on condition that(= if)you don’t go too far away from the river bank.If he had come a few minutes earlier, he could have seen her.（七）让步状语从句

让步状语从句可由although, though, as, even if(though), however, whatever, whether … or, no matter who(when, what, …)等引导。注意：as引导的让步状语从句一般是倒装的。

e.g.Though he is a child, he knows a lot.Child as he is, he knows a lot.Whatever(= No matter what)you say, I’ll never change my mind.（八）方式状语从句

方式状语从句常由as, as if(though), the way, rather than等引导。e.g.You must do the exercise as I show you.He acted as if nothing had happened.（九）比较状语从句

比较状语从句常用than, so(as)… as, the more … the more等引导。e.g.I have made a lot more mistakes than you have.He smokes cigarettes as expensive as he can afford.The busier he is, the happier he feels.（十）使用状语从句时要注意的几个问题

1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。

e.g.We’ll go outing if it doesn’t rain tomorrow.I’ll write to you as soon as I get to Shanghai.2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be，就可省略从句中的“主语 + be”部分。e.g.When(he was)still a boy of ten, he had to work day and night.If(you are)asked you may come in.If(it is)necessary I’ll explain to you again.3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。

e.g.You are to find it where you left it.（地点状语从句）

Tell me the address where he lives.（定语从句，句中有先行词）

I don’t know where he came from.（宾语从句）

Where he has gone is not known yet.（主语从句）

This place is where they once hid.（表语从句）

2)地点where

You'll find itwhere it was.(地点状语从句)

Tell me the addresswhere he lives.(定语从句)

I don't knowwhere he came from.(宾语从句)

Where he has goneis not known yet.(主语从句)
