复合句

复合句(Complex Sentence)分为并列复合句和从属复合句,并列复合句是有并列连词:and、or、but连接;从属复合句由一个主句(Principal Clause)和一个或一个以上的从句(Subordinate Clause)构成。用疑问词引导词主句是全句的主体,通常可以独立存在;从句则是一个句子成分,不能独立存在。从句不能单独成句,但它也有主语部分和谓语部分,就像一个句子一样。所不同在于,从句须由一个关联词(connective)引导。 根据引导从句为主不同大大可分为:主语从句表语从句宾语从句定语从句状语从句等。

1分类

从属复合句可分为:
1).定语从句(The Attributive Clause);
2).状语从句(The Adverbial Clause);
3).名词性从句(The Noun Clause);

2定语从句

定语从句的定义

定语从句在句中作定语,用来修饰一个名词、名词词组或者代词

先行词和引导词

被修饰的名词、名词词组或代词叫做先行词
先行词定语从句之间起连接作用的词叫做引导词
引导词分为“关系代词”和“关系副词”。

关系代词和关系副词

关系代词有:who, whom, whose, that, which, as。
关系副词有:when, where, why。 注意:关系副词里面没有how。
如果要修饰方式,用that或in which引导,或者不用引导词
I don’t like the way (that, in which) he eyed me.
我不喜欢他看我的那个样子。

关系代词:who

关系代词who在从句中主要作主语,在非正式语体里who还可以作从句中的宾语
He is the man whowants to see you.
He is the man who I saw in the park yesterday.

关系代词:whom

He is the man(whom)I saw in the park yesterday.
(whom在从句中作宾语

关系代词:whose

whose 用来指人或物,(只能用作定语, 若指物,它还可以同of which互换)。
They rushed over to help the man whose car had broken down.
Please pass me the book whose cover is green. (of which the cover/the cover of which)

关系代词:which(1)

which指物,在从句中作主语宾语,作宾语时在非正式语体中可以省略。
They needed a plant which didn't need as much water as rice.
The farm(which)we visited yesterday is located in the suburb of Beijing.

关系代词:which(2)

当在which和that面前进行选择的情况下,一般情况下要选which:
1.在非限制性定语从句中通常用which作引导词,而不能用that做非限制性定语从句的引导词。
2. 修饰整个主句
I never met Julia again after that, which was a pity.
3. 修饰谓语部分。
He can swim in the river, which I cannot.
4.介词+ which
They are all questions to which there are no answers.

关系代词:that(1)

that多用来指物,有时也可以用来指人;在从句中作主语或宾语。指物的时候多用that,也可用which。
It’s a question that (which) needs careful consideration.
(指物,作主语。)
Who is the man that is reading a magazine under the tree?
(指人,作主语。)
The girl (that) we saw yesterday is Tom’s sister.
(指人,作宾语,可省略。)

关系代词:that(2)

在以下的情况中,只能用that作引导词,而不能用which作引导词。
1.先行词为all , everything, anything, nothing, little等不定代词时。
All(that)she lacked was training.
2.先行词被形容词最高级修饰时
This isthe best film thatI have ever seen.
3.先行词序数词和the last修饰时
4.先行词中既有人又有物时
They talked about the teachers and the schools thatthey had visited.
5.主句是含有who或which的特殊疑问句,为了避免重复时

3状语从句

地点状语从句

地点状语从句通常由where, wherever 引导。
Where I live there are plenty of trees.
Wherever I am I will be thinking of you.

方式状语从句

方式状语从句通常由as, (just) as…so…, as if, as though引导。
1) as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如:
Always do to the othersasyou would be done by.
你希望人家怎样待你,你就要怎样待人。
Aswater is to fish,soair is to man.
我们离不开空气,犹如鱼儿离不开水。
Just aswe sweep our rooms,sowe should sweep backward ideas from our minds.
正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。
2) as if, as though
两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的","好像……似的",例如:
They completely ignore these factsas if (as though)they never existed.
他们完全忽略了这些事实,就仿佛它不存在似的。(与事实相反,谓语虚拟语气。)
He looksas if (as though)he had been hit by lighting.
他那样子就像被雷击了似的。(与事实相反,谓语用虚拟语气。)
It looksas ifthe weather may pick up very soon.
看来天气很快就会好起来。(实现的可能性较大,谓语用陈述语气。)
说明:as if / as though也可以引导一个分词短语、不定式短语或无动词短语,例如:
He stared at meas ifseeing me for first time.
目不转睛地看着我,就像第一次看见我似的。
He cleared his throatas ifto say something.
他清了清嗓子,像要说什么似的。

原因状语从句

比较:because, since, as和for
1) because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或 since。
I didn't go,becauseI was afraid.
Since /Asthe weather is so bad, we have to delay our journey.
2) 由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就只能用for。
He is absent today,because / forhe is ill.
He must be ill,forhe is absent today.

目的状语从句

表示目的状语的从句可以由that, so that, in order that, in case等词引导,例如:
You must speak louderso that /in orderthat you can be heard by all.
Better take more clothesin casethe weather is cold.

结果状语从句

结果状语从句常由so… that 或 such…that引导,掌握这两个句型,首先要了解so 和 such与其后的词的搭配规律。
比较:so和 such
其规律由so与such的不同词性决定。such 是形容词,修饰名词或名词词组,so 是副词,只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little连用,形成固定搭配。
sofoolish,sucha fool
sonice a flower,sucha nice flower
somany / few flowers,suchnice flowers
somuch / little money,suchrapid progress
somany people,sucha lot of people
( so many 已成固定搭配,a lot of 虽相当于 many,但 a lot of 为名词性的,只能用such搭配。)
so…that与such…that之间的转换既为 so与such之间的转换。
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school

条件状语从句

连接词主要有 if, unless, as/so long as, on condition that 等。.
unless = if not.
Let's go out for a walkunlessyou are too tired.
Ifyou arenottoo tired, let's go out for a walk.

让步状语从句

though, although
注意:当有though, although时,后面的从句不能有but,但是 though 和yet可连用
Althoughit's raining, they are still working in the field.
3) even if, even though. 即使
We'll make a tripeven thoughthe weather is bad.
4) whether…or- 不管……都
Whetheryou believe itornot, it is true.
5) "no matter +疑问词" 或"疑问词+后缀ever"
No matterwhat happened, he would not mind.
Whateverhappened, he would not mind.
替换:no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意:no matter 不能引导主语从句宾语从句
(错)No matter what you say is of no use now.
(对)Whatever you say is of no use now.(无论你说什么都是无用的)
你现在说什么也没用了。(Whatever you say是主语从句)
(错)Prisoners have to eat no matter what they're given,
(对)Prisoners have to eatwhateverthey're given. 囚犯们只能给什么吃什么。

比较while, when, as

1)as, when 引导短暂性动作的动词。
Just as / Just when / WhenI stopped my car, a man came up to me.
2)当从句的动作发生于主句动作之前,只能用when 引导这个从句,不可用as 或 while。
Whenyou have finished your work, you may have a rest.
3)从句表示"随时间推移"连词能用as,不用when 或while。
Asthe day went on, the weather got worse.
日子一天天过去,天气越变越坏。

比较until和till

这两个连词意义相同。肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可 以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
I sleptuntilmidnight. 我一直睡到半夜时醒了。
WaittillI call you. 等着我叫你。
(在肯定句中可用before代替 Let's get in the wheatbeforethe sun sets.)
She didn't arriveuntil6 o'clock.
Don't get off the busuntilit has stopped.
1)Until可用于句首,而till通常不用于句首。
Untilyou told me, I had heard nothing of what happened.
直到你告诉我以前,出了什么事我一点也不知道。
2)Until when疑问句中,until要放在句首。
---Until whenare you staying? 你呆到什么时候?
---Untilnext Monday. 呆到下周一。
注意否定句可用另外两种句式表示。
(1)Not until …在句首,主句倒装
Not untilthe early years of the 19th centurydid manknow what heat is.
直到19 世纪初,人类才知道热能是什么。
Not untilI began to workdid Irealize how much time I had wasted.
直到我开始工作,我才认识到了我已蹉跎了几多岁月。
(2) It is not until… that…
10 表示"一…就…"的结构
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示"一…就…"的意思,例:
I hadhardly / scarcelygot homewhenit began to rain.
I hadno soonergot homethanit began to rain.
As soon asI got home, it began to rain.
注意:如果hardly, scarcely 或no sooner置于句首,句子必须用倒装结构:
Hardly / Scarcely had Igot home when it began to rain.
No sooner had Igot home than it began to rain.

4名词性从句

主语从句

复合句中充当主语成分的句子叫做主语从句。常规主语从句,即句子在复合句中充当一个主语。主语从句的时态:不受主句的时态影响和限制。(1)That he finished writing the composition in such a short time surprised us all.(2)Whether we will go for an outing tomorrow remains unknown.(3)Who will be our monitor hasn't been decided yet.(4)Whom we must study for is a question of great importance.(5)What caused the accident remains unknown.(6)Whatever you did is right.(7)Who the watch belongs to is unknown.(8)What we need is time.(9)What we need are good doctors.小结:(1)引导主语从句连词有that,whether,who,what,whatever等(2)连词位于句首不能省略(3)主语从句大多数情况下视为第三人称单数,但也有例外,如例(9)
注意: 当what引导的名词性分句作主语时,主谓一致问题极为复杂。著名学者周海中教授在论文《关于what-分句作主语的主谓一致问题》中就这一问题做了深入研究,并给出了10种的主谓一致关系。这些一致关系值得英语学习者和使用者特别注意。

宾语从句(The Object Clause)

在句子中起宾语作用的从句叫做宾语从句宾语从句引导词主语从句引导词相同。宾语从句可以作及物动词的宾语,作短语动词的宾语,介词的宾语。

·宾语从句:短语动词的宾语
Please go and find out when the train will arrive.
·宾语从句:介词的宾语

·宾语从句:否定的转移

我相信她8点之前不会到。
表语从句(The Predicative Clause)
·表语从句

What the police want to know is when you entered the room.
This is what we should do.

as if, as though, because也可用来引导表语从句
She seems as if she had done a great thing.
It is because you eat too much.
主语是idea, notion, proposal, suggestion, request等名词时,作表语从句的动词为原形动词或should+原形动词。
My suggestion is that we(should)go and help him.
Our only request is that thisshouldbe settled as soon as possible.
同位语从句(The Appositive Clause)
· 同位从句一般跟在某些名词如answer(答案),hope(希望),fact(事实),belief (信仰),news(消息),idea(主意;观念),promise(承诺),information(信息),conclusion(结论),order(命令), suggestion(建议),problem(问题),thought (想法)等后面。例如:
I had noidea thatyou were here.
She told us herhope thatshe would become a pianist.
He made apromise thathe would never come late.
·同位语从句:whether
whether可以引导同位语从句,而定语从句不能用whether作为引导词

I have small doubtwhetherhe is suitable for the job.
what可以引导同位语从句,而定语从句不能用what作为引导词
