英语高考从句_高考从句总结

18.1 关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。

1）who, whom, that

这些词代替的先行词是人的名词或代词，在从句中所起作用如下：

Is he the man who/that wants to see you?

他就是你想见的人吗？（who/that在从句中作主语）

He is the man whom/ that I saw yesterday.

他就是我昨天见的那个人。（whom/that在从句中作宾语）

2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：

They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。

Please pass me the book whose (of which) cover is green. 请递给我那本绿皮的书。

3）which, that

它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：

A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）

The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语）

18.2 关系副词引导的定语从句

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。

1）when, where, why

关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用，例如：

There are occasions when (on which) one must yield. 任何人都有不得不屈服的时候。

Beijing is the place where (in which) I was born. 北京是我的出生地。

Is this the reason why (for which) he refused our offer? 这就是他拒绝我们帮助他的理由吗？

2）that代替关系副词

that可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略，例如：

His father died the year (that / when / in which) he was born. 他父亲在他出生那年逝世了。

He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。

18.3 判断关系代词与关系副词

方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如：

This is the mountain village where I stayed last year.

I'll never forget the days when I worked together with you.

判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）

（错） This is the mountain village where I visited last year.

（错） I will never forget the days when I spent in the countryside.

（对） This is the mountain village (which) I visited last year.

（对） I'll never forget the days (which) I spent in the countryside.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。

方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。

例1. Is this museum ___ you visited a few days age?

A. where B. that C. on which D. the one

例2. Is this the museum ____ the exhibition was held.

A. where B. that C. on which D. the one

答案：例1 D，例2 A

例1变为肯定句： This museum is ___ you visited a few days ago.

例2变为肯定句： This is the museum ___ the exhibition was held.

在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。

而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。

关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语) 。

18.4 限制性和非限制性定语从句

1) 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：

This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）

The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）

2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：

Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。

My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。

This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。

3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：

He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。

Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。

说明：关系代词that和关系副词why不能引导非限制性定语从句。

名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功同名词一样。

一．主语从句

主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。

1. It 作形式主语和it引导强调句的比较

It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人是也可用who/whom。例如：

It is a pity that you didn’t go to see the film.

It doesn’t interest me whether you succeed or not.

It is in the morning that the murder took place.

It is John that broke the window.

2. 用it 作形式主语的结构

(1) It is ＋名词＋从句

It is a fact that … 事实是…

It is an honor that …非常荣幸

It is common knowledge that …是常识

(2) it is ＋形容词＋从句

It is natural that… 很自然…

It is strange that… 奇怪的是…

(3) it is ＋不及物动词＋从句

It seems that… 似乎…

It happened that… 碰巧…

(4) it ＋过去分词＋从句

It is reported that… 据报道…

It has been proved that… 已证实…

3. 主语从句不可位于句首的五种情况

(1) if 引导的主语从句不可居于复合句句首。

(2) It is said , (reported) …结构中的主语从句不可提前。例如：

It is said that President Jingo will visit our school next week. (right)

That President Jiang will visit our school next week is said. (wrong)

(3) It happens…, It occurs… 结构中的主语从句不可提前。例如：

It occurred to him that he failed in the examination. (right)

That he failed in the examination occurred to him. (wrong)

(4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如：

It doesn’t matter whether he is wrong or not. (right)

Whether he is wrong or not doesn’t matter. (wrong)

(5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如：

Is it likely that it will rain in the evening? (right)

Is that will rain in the evening likely? (wrong)

4. What 与that 在引导主语从句时的区别

What 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：

1) What you said yesterday is right.

2) That she is still alive is a consolation.

二．宾语从句

宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。

1. 作动词的宾语

(1) 由that引导的宾语从句（that 通常可以省略）,例如：

I heard that be joined the army.

(2) 由what, whether (if) 引导的宾语从句，例如：

1) She did not know what had happened.

2) I wonder whether you can change this note for me.

(3) 动词＋间接宾语＋宾语从句。例如：

She told me that she would accept my invitation.

2. 作介词的宾语

例如：Our success depends upon how well we can cooperate with one another.

3. 作形容词的宾语

例如：I am afraid (that) I’ve made a mistake.

That 引导的从句常跟在下列形容词后作宾语：

Anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。

4. It 可以作为形式宾语

It 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如：

We heard it that she would get married next month..

5. 后边不能直接跟that 从句的动词

这类动词有Allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。例如：

I admire their winning the match. (right)

I admire that they won the match. (wrong)

6. 不可用that从句作直接宾语的动词

有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的有Envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：

He impressed the manager as an honest man. (right)

He impressed the manager that he was an honest man. (wrong)

7. 否定的转移

若主句谓语动词为Think, consider, wuppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：

I don’t think this dress fits you well.（我认为这件衣服不适合你穿。）

三．表语从句

表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语＋连系动词＋表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如：

1) The question is whether we can make good preparation in such a short time.

2) This is why we can’t get the support of the people

3) But the fact remains that we are behind the other classes.

4) The reason he is late for school is that he missed the early bus.

四．同位语从句

同位语从句就是在复合句中作名词的同位语的名词性从句。

1. 同位语从句的功能

同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：

1) The king’s decision that the prisoner would be set free surprised all the people.

2) The order that all the soldiers should stay still is given by the general.

2. 同位语在句子中的位置

同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：

He got the news from Mary that the sports meeting was put off.

3. 同位语从句与定语从句的区别

(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。

(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：

1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）

2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）
