注意：在强调结构中，如被强调部分为时间状语或地点状语，其后的连接词也绝不能为when 或where，而应用that 。在复习中，一定要注意句式的不同。 It was in Shanghai that I bought the (that引起强调句) It was Shanghai where I bought the (where引起定从)

It was twelve o'clock when we arrived (when引起时间状语从句) It was at twelve o'clock that we arrived (that 引起强调句)

it，one，that 的区别：作为代词，这三个词的对比使用是高考的热点之一。 —Why don't we take a little break? —Didn't we just have __________?

The Parkers bought a new house but _________will need a lot of work before they can move

one 用以指代同类事物中的任一，that 特指性强，指代可数与不可数词，而it指代上文提过的同一事物。

高中英语知识点总结归纳 第6篇

1、什么是状语从句状语从句(Adverbial Clause)状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。

2、状语从句考点分析：

1.状语从句虽然有完整的主谓结构，却是不能独立的从句。

2.状语从句它由从属连词引导成为整个句子一个不可缺少的部分。

3.考查的热点有条件、时间、地点、让步等状语从句的连接词词义辨析.

4.动词的时态呼应、状语从句的省略等。

5.题干结构呈交叉和综合特征，选项设计多从定语从句和名词性从句的角度进行思维干扰。

3、状语从句时态特点一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如：

I will call you as soon as I arrive in Beijing.我到北京就将给你打电话。

(这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，绝不可用will arrive)

As soon as I have finished this work, I will have gone home.我一完成此工作，就回家。

(从句中的谓语动词用现在完成时have finished，表示将来完成时,绝不可用will have finished)

If he comes back, please let me know.如果他回来了，请通知我。

(从句中的谓语动词用comes back,表示一般将来时，绝不可用will come back)

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.

2让步状语从句1、though,although,as的区别

A、Though,although的主句中可以用yet, still, nevertheless,但不可使用but。

B、though引导的从句可以倒装，也可以不倒装;as引导的从句必须倒装;although引导的从句不能倒装。其结构为：形容词/分词/副词/动词原形/名词(无冠词)+as/though+主语+谓语……

2、though可用作副词，放在句末，意为“不过，但是”。Although无此用法。

3、某些短语也引导让步的从句或短语，意为“尽管”，如：in spite of the fact that, despite the fact that,regardless of(the fact that)

句子种类

1、陈述句的否定

(1)在含有宾语从句的主从复合句中，当主句的谓语动词是think, expect, believe, suppose, guess, fancy,imagine等，且主句主语是第一人称时，宾语从句谓语的否定习惯上要移到主句谓语上，如: I don't think he is right.

(2)含有否定意义的副词never, seldom, hardly, scarcely, rarely, barely的句子应视为否定句，如: I have never been there before.

2、反意疑问句

(1)need和dare既可作情态动词，又可作实意动词，在反问部分须加以区别，如We needn't leave, need we? We don't need to leave, do we?

(2)陈述部分出现否定意义的副词或代词如never, seldom, few, hardly, little等时，反问部分须用肯定形式，如：He seldom comes, does he?

(3)陈述部分用不定代词作主语时，反问部分的主语用it，如：Nothing can stop me, can it?

陈述部分用everybody, everyone, somebody, someone，等作主语时，反问部分常用it，有时也用they，如:Everybody knows that, don't they?

(4)陈述部分包括used to时，反问部分可有两种形式，如: You used to get up early, usedn't (didn't) you?

(5)陈述部分是"there + be"结构时，反问部分用there，如:There's something wrong with you, isn't there?

(6)陈述部分是含有宾语从句的主从复合句时，反问部分的主语和谓语应和主句保持一致，如: He never told others what he thought, did he?

但，如果是I think , I believe等+宾语从句时，反问部分须和从句的动词保持一致，如，I don't think he is right, is he? I don't believe he does that, does he?

3、感叹句

用what或how,

What a beautiful park it is.

How beautiful a park it is.

How beautiful the park is.

How we worked!

4、祈使句

Take care!

Don't stand there.

Please open the door for the old lady.

3不定式的构成1、不定式的一般式：不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生，或是在它之后发生。

如：They invited us to go there this summer.他们邀请我们今年夏天去那儿。He stood aside for me to pass.他站到一边让我通过。

2、不定式的完成式：不定式的完成式所表示的动作在谓语所表示的动作之后发生，它在句中可作表语、状语、宾语，有时也可作主语、定语等。

如：She seemed to have heard about this matter.她似乎已听说过这件事。

I am sorry to have kept you waiting so long.我很抱歉让你等了这么久。

I meant to have told you about it,but I happened to have an important thing to do.我本来想告诉你这件事的，但我碰巧有一件重要的事要做。

It has been an honor for me to have traveled so much in your country.对我来说，在你们国家旅行这么多地方是一件很荣幸的事情。

3、不定式的进行式：不定式的进行式表示正在进行的与谓语动词同时发生的动作。它在句中可以用作除谓语以外的所有成分。

如：It’s nice of you to be helping us these days.你真好，这些天一直帮我们。

He pretended to be listening to the teacher carefully.他假装在认真地听老师讲课。We didn’t expect you to be waiting for us here.我们没料到你一直在这儿等我们。

4、不定式的完成进行式：如果不定式表示的动作是谓语所表示

5、动词不定式的否定形式是由not或never加不定式构成。如：Try not to be late again next time.尽量下次不要再迟到。He wished us never to meet her again.他希望我们永远不要再见到她。

6、疑问词+动词不定式：不定式和疑问词whether,what,which,whom,where,when,how,why等连用可以在句中起名词的作用，通常跟在tell,know,show,decide,learn,wonder,explain,advise,teach,discuss,find out等动词后面作宾语，有时也可以充当主语、表语等。

如：On hearing the news,he didn't know whether to laugh or to cry.听到这个消息，他不知道该哭还是该笑。

When to hold the meeting has not decided.什么时候开会还没有决定。

The most important problem is how to get so much money.最重要的事情是如何搞到这么多钱。

介词后一般不直接接不定式，但可以接疑问词+不定式短语作宾语。

如：Mary gave some advice on how to learn English.玛丽提了一些如何学习英语的建议。

I have no idea of how to do it.我不知道该怎么做。
