英语主要从句 精讲精练
从句的基本构成形式: 一、(引导从句的)关联词 + 陈述句
常见的关联词:
1、引导多种从句的常见关联词: what , when, where, who, which, why, how, that, as, since, whether, which, whatever, whenever, if, etc.
2、引导一种从句(常为状语从句)的常见关联词:until, till, after, before, than, so long as, as far as, as soon as, the moment, every time, each time, as if, now that, even if(thought), by the time, in order that, as…as, once, in case, immediately, how long, etc.
二、主语从句 NOTICE: What we need most are books.
主语从句三要素: 1、关联词不能省略 2、谓语动词用单数 3、从句用陈述语序
常见引导词:what, when, where,which, who, that,whether, how ,whatever, whoever
Whether it will do us harm or good remains to be seen. Is what you told me really true?
I don’t think that whatever happens is right.
三、表语从句: 1、关联词不能省略 2、从句用陈述语序
常见引导词: what, when, where,why, whether, how,that, because, which,
What surprised me most was that he spoke English so well.
The question is how what you’ve said can be put into practice.
The reason (why ) he didn’t come is that he was ill.
It (This , That) is because iron contains more carbon than steel.
四、同位语从句: 1、关联词不能省略 2、从句用陈述语序
从句的名词后接同位语: fact, idea, word,promise, saying,problem, news
常见引导词: that, whether, where, how, etc.
The facts that he succeeded in the experiment pleased us.
An idea came to her that she might do that in another way.
Scientists have argued over the problem whether there is life on other planets.
五、宾语从句
1.从句用陈述语序: Free movie tickets will be given to whoever comes first.
Parents generally buy whichever books their children want.
I realized that what I said was not exactly what I meant to say.
I once read that “The beauty of life is its changes “ and that “The art of life lies in a constant readjustment(适应)to our surroundings.”
Sleep-teaching will only hammer into(强硬灌输)your head what you have studied already while you are awake.
2 . it可做形式宾语代替宾语从句: We all thought it a pity that he didn’t come.
六、名词性从句的综合问题
1、whether与 if: If 只能引导宾语从句,不能引导主语从句、表语从句、同位语从句
The question is whether it is worth doing
2、which ,what 不能引导同位语从句,,what 不能引导定语从句。
3、whatever, whichever, whoever可以引导名词性从句,“一切,任何,无论”
Whoever telephones, tell them I’m out. Whichever day you come, we’ll be pleased to se you.
Whatever problem you have, you can always come to me for help.
七、What-clause
1、what = something that /which(即含“内容”)
2、可以引导主语从句、表语从句、宾语从句:What money I have has been given to you.
3、在从句中担当主语、宾语、表语、定语:Show me what you have written.
He is not what he was a few years ago. What matters most is good health.
FIU has opened (that ) what it says is the first computer art in the US.
4.引导插入语:He is handsome, and what is more, very rich,
_____ was most important to her, she told me, was her family.
A. It B. This C. What D. As (08山东)
C 此题考查主语从句连词的选择。关键在于看出she told me是插入语,从结构上不影响整个句子的表达。据题意“她告诉我,对她来说最重要的是她的家庭”,第二个was 是整个句子的谓语动词。所选词须是连词用来引导主语从句。故可排除A,B。as
不能引导主语从句,也可排除。what引导名词性从句在从句中做主语。
八、状语从句

九、定语从句
1.总论: 定语从句在句中使用频率非常高,它分为限制性或非限制性两种。限制性定语从句上用来修饰人物事物,它与所修饰的名词或名词词组不可分割,非限制性定语从句是用来对修饰的人或物作补充说明。
定语从句的关键是:①引导定语从句的关联词;②被定语从句所修饰的先行词 。
关联词的三要素:①引导功能(引导定语从句,连接主从句);②替代功能(代表所修饰的先行词);③成分功能(在从句中担当一定成分)
2.关系代词: that which who whom whose as
① 关系代词引导定语从句并在从句中作主语,从句谓语动词在人称和数上要和先行词一致。He does’t like the book which (that) is very thick. (He doesn’t like he book. It is very thick.)
② 关系代词引导定语从句并在从句中作宾语,此时,从句中要注意不要重复宾语,而且which, that, who, whom还可以省略.
The letter (which, that) I received was from Miss Li. (The letter was from Miss Li. I received it.)
He is the man (who,whom) we met in the hotel. (He is the man. We met him in the hotel.)
③ 关系代词whose引导定语从句并在从句中作定语,whose可指人也可指物.
I haven’t met Mr Li,whose son is my teacher now.
(I haven’t met Mr Li. His son is my teacher now.)
The computer whose CPU doesn’t wok has to be repaired.
(The computer has to be repaired. Its CPU doesn’t work.)
3.关系副词: when where why ; 它们引导定语从句并在从句中作状语
when = in / on / at + which (时间)
where = in / on / at + which (地点)
why = for which (原因)
比较: This is the day that I’ll never forget. (This is the day. We met on that day.)
This is the day when (on which) we met (him).
We’ll go to the factory that you visited. (We’ll go to the factory. He works there.)
We’ll go to the factory where (in which) he works.
We don’t know the reason why (that) he fell ill.
4.which, that的区别
① that 可指人或物,which只能指物:I'll never forget the persons and the school that I saw.
② 先行词被序数词、形容词最高级修饰用that:This is the longest pencil (that) I have ever seen.
③ 先行词是all , little, -thing, 或者被all, no, every,little,only等修饰时,用that
That’s all (that) I want to say.
④ which 可以引导非限制定语从句,而that不可以:The book is red, which surprises me,
⑤ that前不加介词:This is the house in which he lives. (that he lives in)
5.带介词的定语从句
① 介词通常放在which, whom之前 :Is this the factory in which you work?
NOTICE: ⑴ 含介词的短语动词,介词不提前:That’s the boy you are looking for.
⑵ 非限制性定语从句中,介词一般提前:The man, about whom we had heard, was here yesterday.
② n. (pron.) + of which / whom: The persons, most of whom were students, enjoyed the play.
There are pyramids in Egypt, the largest of which (of which the largest) is the Great Pyramid.
③ 复杂介词 + which / whom(通常倒装)
They stayed in a big hotel, in front of which was a garden.
He came to a house, on the door of which was a plate.
6. as作关系代词
① 可以引导定语从句,并在从句中作主语、宾语和表语,从句既可以放在句首也可以放在句子后部。“正如……”,“象……(一样的)”
He was strongly against the plan as could be expected.
As everybody can see, he has done what he should do.
② such (…) as , the same (…) as: I have the same trouble as you (have).
My hometown is no longer the same as it was.
Such views as he has mentioned should be discussed.
③ 比较练习:so…as ; so…that; such (…) as; such(…) that
⑴Here is so big a stone (such a big stone) no one can lift.
( no one can lift it.
⑵The instrument is not I saw on the exhibition.
⑶The weather was I couldn’t go out.
⑷She isn’t such a careless student you think she is.
(KEY: ⑴as (that) ⑵such as ⑶such that ⑷as )
7.其它: ① 插入语: He ran from the station which I thought was impossible.
( which, I thought, was…)
② 并列主从句,两个或多个定语从句由and, but, or连接,共同修饰一个词: I’m talking about friends who care deeply about each other, who support each other, and who make life worth living.

二.◆典型陷阱题分析◆答案
1. 【陷阱】可能误选B。许多同学一看选项首先就排除了C和D,认为这样两个“引导词”叠用的情况不 可 能。在A和B两个选项中,选项A肯定不行,因为它引导宾语从句时不能充当句子成分,所以便选择了B。
【分析】正确答案选 D。第一个what 用作动词 meant 的宾语,第二个what 用作动词 said 的宾语,即 在 none of us understood what what he said meant 中,none of us understood 为主句,what what he said meant 为宾语从句,而在此宾语从句中又包括有 what he said 这样一个主语从句。
2. 【陷阱】可能误选A。【分析】最佳答案选 C。有的同学误选A,是因为认为介词后应接关系代词 which,但实际上,若填关系代词,其前没有先行词,这根据不是一个定语从句。另外,由于 had happened 缺主语,所以B和 D也不能选。
3.【陷阱】据字面意思误选A或B。【分析】答案选 D。假若选A或B,那么转换成陈述句即为:This is you want to say. / That is you want to say. 显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say? 其中的that 为句子主语,all 为表语,you want to say 为定语从句,用以修饰all。
4.【陷阱】可能误选D,认为 when 后应用疑问句词序。【分析】最佳答案选 B。第一个when引出的是一个特殊疑问句,故用疑问词序;第二个 when 引出的是主语从句,故其后用陈述句词序。(1) C (2) C
5.【陷阱】几个干扰项均有可能误选。
【分析】此题最佳答案为D。首先可以排除A和C,因为空格处实为一个宾语从句,所以不能用疑问句词序。另一方面,但按英语习惯,当用于指代身份不明的人时,要用代词it,而不用 he 或she等。比较以下两句:Mr Smith is at the door. He wants to see you. 史密斯先生在门口,他想见你。
Someone is at the door. It may be the postman. 有个人在门口,可能是邮递员。
第一句因前面指明了是 Mr Smith,所以后面用代词 he;而第二句因前面用的是不定代词 someone,说明此人身份尚不明确,故其后用了代词 it 来指代。
6. 【陷阱】此题易误选 A或B:选 A 认为这是指人的,故用who;选B认为这是非限制性定语从句,两者都是误认为这是定语从句(注意没有先行词)。 答案应选C。that引导的是一个宾语从句,用作动词 know 的宾语,它只是被句中的插入语 my dear friend 隔开罢了。(1) C (2) C (3) C 前面两题 that 引导宾语从句,后面一题 that同位语从句(修饰the news)。
◆精编陷阱题训练◆【答案与解析】1. 选D。what made matters worse 是主语从句(注意其后有谓语动词was),相当于 the thing that made matters worse。
2. 选A。what 引导的是表语从句,相当于 the thing that it takes to do anything well。
3. 选C。that 引导的是一个主语从句,句首的it为形式主语。
4. 选 C。答句为省略句,其完整形式为 I was trying to prove to the police where I was last night,在此 where 引导的是一个宾语从句。类似地,下面选 C:
“_______ made her struggle to become an artist so hard?” “______ she was a woman.”
A. What, What B. That, That C. What, That D. That, What
5. 选D。what 引导的是表语从句,what 在此相当于 the things that。
6. 选 C。句首的 it 是形式主语,空格处所填词用于引导主语从句。由于该主语从句中又缺主语,故排除A、B、D。(注意:不能选 A,因为 that 引导名词性从句时不能充当句子成分)
7. 选 A。第一空填 what,是因为该主语从句中的动词 understand 缺宾语;why 和 because 均可引导表语从句,其区别是: why 引导表语从句强调结果,because 引导表语从句强调原因。句中空格后文表明的是结果,故用 why。
8. B。what 在此引导主语从句且在从句作宾语,它相当于 the thing that。
9. B。两空均填 what,均用于引导宾语从句,因为两个宾语从句中的动词 said 和do 均缺宾语,而在各个选项中只有 what 可用作宾语。
10. 选 A。what 引导宾语从句。由于动词 wants 缺宾语,所以填 what。句意是:当你找工作面试回答问题时,请记住这条黄金定律:永远给予对方确实想要的东西。
11. 选 A。I can to save them 为 I can do to save them 之略,此句中的 do 缺宾语,故选 whatever。
12. 选 B。that 在此引导主语从句,无词义,也不充当句子成分。注意不要根据中文意思选 D,因为 because 不用于引导主语从句。
13. 选 C。两个空格处均为引导宾语从句的引导词,而四个选项中两者可引导宾语从句的只有 C。
14. 选 B。比较 That’s why… 与 That’s because…
:前者用于强调结果,后者用于强调原因。如下面一题选 D:I got wet all through. _______ I had neither a raincoat nor an umbrella.
A. It’s the reason B. That’s why C. There’s why D. That’s because
15. 选 D。由 is worth praising 这一谓语可知前面是主语从句,排除不能引导从句的 B 项和 C 项;whoever 引导主语从句表示“任何……的人”,在此它相当于 anyone who。
16. 选 A。how 引导主语从句,that 引导同位语从句。
