① 英语各大复合句
不知道你现在是什么阶段,初中还是高中.
通常讲写作的时候,会提到高级句型和高级结内构容,但高级结构包含据我的理解,也有平时改卷时的总结,有以下的:
介词结构,非谓语,倒装句,省略句,虚拟语气等
而你所说的复合句,应该指的是相对简单的:定语从句,名词性从句,状语从句等.
象定语从句在写作中不算作高级结构,只能说比通篇的简单句要好一些.
如果你真要提高的话,可以发短信给我.我给你我的QQ号,你有问题可以问问我.最近学生小高考所以我们时间相对多一些.
当然如果你的问题相对简单,可以到中学学科网的英语教与学来,我是那儿的版主,同时那儿也有很多热心老师和学生回答问题的.
祝你成功^_^
P.S.最重要的应该是非谓语了,看那么多年高考题考了那么多非谓语就知道了.
② 请帮忙总结全面的有关英语复合句的语法,谢谢
在英语里,一定的句子成分由一定的词类来担任,如表语可由形容词、名词、代词担任。一般在句中实词可担任句子成分,虚词不能独立担任成分。
短语或称词组,一般是围绕一个中心词(按一定的语法规则组合在一起的一组词),在句中可单独担任句子成分。(从形式上可分为名词短语、形容词短语、动名词短语等)
从句内含主语和谓语,表达一定的概念,但不成为一个独立句子的一组词,叫从句。在句中可担任任何句子成分。(一般由连词、关系代词或关系副词所引导; 因此根据
不同的句子成分,可分为定语从句,主语从句,宾语从句等)
句子:一般按结构可分为简单句、并列句、复合句和并列复合句四种。
简单句:只包含一个主谓结构的句子。(可以是一个主语+一个谓语,也可以是“两个或两个以上的并列主语+两个或两个以上的并列谓语)Tom and Jack studied in the same class and lived in the same room.
还有个学者说:简单句只包含一个主谓结构,而句子的各个成分都欲单词或短语表示。
并列句:包含两个以上并列的简单句的结构的句子。并列的简单句叫分句,分句与分句之间通常由并列连词连接(and,but,for,or,so,nor 等) My father is a doctor, so I would like to follow his footsteps. (很初级的学者说 只能放中间且前面要有逗号)
复合句: 包含一个主句和一个以上从句的结构的句子叫复合句。 Because I studied hard, I passed the exam.(很初级的学者说 从属连词放前时 要有逗号,放中间便不用)
(从句只起一个句子成分的作用,因此从句就有主语从句、定语从句、状语从句等)
并列复合句:并列句中的分句里如含有从句,这种结构的句子叫并列复合句。She recognized the two men who robbed the rank yesterday and decided to call the police.
③ 英语复合句的用法
这是个宾语从句,they can't take part in 翻译过来就是他们不能参加,不能参加什么呢?版这里就少一个宾语,所以权就用what来表达不能参加的内容 take part in what they see 不能参加他们看到的
④ 英语作文中常用复合句句型,求附中文及语法
并列复合句
1、基本概念:
并列复合句是由两个或两个以上并列而又独立的简单句构成。两个简单句常由并列连接词连在一起;但有时不用连接词,只在两个简单句之间用一逗号或分号。
2、常见的并列句:
(1) 用来连接两个并列概念的连接词有and , not only…but also…, neither…nor…等,and所连接的前后分句往往表示先后关系、递进关系。前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。
(2) 表示在两者之间选择一个, 常用的连接词有or,otherwise,or else,either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。
(3) 表明两个概念彼此有矛盾、相反或者转折, 常用的连接词有but,yet,still ,however等,前后分句时态一致。
(4) 说明原因, 用连接词for ,前后分句时态一致。
(5) 表示结果,用连接词so, 前后分句时态一致。
主从复合句
1、概念:
主从复合句由一个主句和一个或一个以上的从句构成。主句为句子的主体,从句只用作句子的一个次要成分,不能独立成为一个句子。从句通常由关联词引导,并由关联词将从句和主句联系在一起。如:While the grandparents love the children, they are strict with them.(爷爷奶奶们很爱孩子,同时对他们也严格要求。) / It seemed as if the meeting would never end.(看起来会议没完没了。) / Hurry up, or (else) you'll be late.(快点, 要不然就来不及了。) / However I cook eggs, the child still refuses to eat them.(不管我用什么方法煮鸡蛋,小孩还是不肯吃。)
2、分类:
从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。(参见以下各条)
3、各从句在句子中的位置以及用法:
(1) 表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后
例如:That is why he did not come to school yesterday. / It is because you are so clever.
(2) 宾语从句:在句子中作及物动词或介词的宾语。
①基本形式:(主句+)连词+从句主语+从句谓语+...
② 关于宾语从句连词的选择:
若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;
若从句来源于一个一般疑问句,连词则用if 或whether;
若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)
例如:They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where can he get such medicine? )
③ 宾语从句的时态问题:如果主句是现在时,从句则用现在某一时态,甚至可以用过去时;
如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如:I think I will do better in English this term. (我想本学期我的英语会学得好点。) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。)
④ 下列结构后面的从句一般也作为宾语从句看待:
be sorry / afraid / sure / glad +that从句,如:I’m sorry I’m late. (对不起,我迟到了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。)
(3) 状语从句:在复合句中作状语,其位置可以在主句前或主句后。状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。
时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。如: When you finish the work, you may go out to play with Sam. (你完成工作就可以出去和Jim一起玩了。) / I won’t leave until Mum comes back. (妈妈回来了我才会走。)
地点状语从句通常由 where, wherever等引导。如:Go back where you came from! (哪里来还滚到哪里去!) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会忘记去抓住那个偷我项链的贼,无论他会在哪里。)
原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如:He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。)
目的状语从句通常由so that..., so...hat..., in order that... 等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如:He got up earlier so that he could catch the first train. (他起身更早为的是赶上第一班车。)
结果状语从句通常由 so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如:He lost so many bikes that he decided never to buy a new one. (他丢了那么多辆自行车,他决定再也不买新车了。)
比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如:Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多)
让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如:Even if you pay the debt(债务) for me, I will not thank you because it has nothing to do with me. (即使你替我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿了一件T恤衫,尽管天很冷。)
条件状语从句通常由if, unless, as long as等引导,条件状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。You will certainly fail in the coming final exams unless you work much harder. (即将来到的期末考试你肯定考不及格,除非你更用功。) / If it doesn’ t rain tomorrow, we shall go hiking. (如果明天不下雨我们就要去徒步旅行。)
[注意] 1、because与so;(al)though与but;if与so不可以同在一个句子中成对出现。2、时间、条件、原因,让步状语从句放在句首时需要用逗号与主句隔开。
(4) 定语从句:在复合句中作定语用修饰句子中某一名词或代词的从句叫定语从句。
① 定语从句的位置:放在名词或代词的后面。如:The man who has an umbrella in his hand is my uncle. (手上抓了一把雨伞的人是我的叔叔。)
② 语法术语的改变:被修饰的名词或代词称为先行词;引导定语从句的连接词称为关系词,其中that、which、who称为关系代词,where、when、how称为关系副词。
③ 关系代词或关系副词的作用:
关系代词who、whom 和whose指人,分别在从句中作主语、宾语和定语。which指物that多指物, 有时也指人,它们在从句中可以作主语或宾语。定语从句中关系代词作从句宾语时可以省略。This is the thief (that/who/whom) we have been looking for these days. (这个就是我们近日一直在找的小偷。) / Please find a room which is big enough for all of us to live in. (请找一间足够大能住下我们全体的房间。)
关系副词when或where引导定语从句时,它们在从句中分别作时间状语和地点状语。如:This is the room where they had a quarrel a week ago. (这是一个星期前他们吵架的房间。) / I can never forget the day when I first saw you. (我永远不会忘记第一次见到你的日子。)
④ 限制性定语从句和非限制性定语从句。限制性定语从句在句中不能省略,否则主句意思就不完整。非限制性定语从句和主句之间往往用逗号分开,这种从句是一种附加说明,如果从句子中省去,也不致于影响主句的意思。如:She spent the whole evening talking about her latest book, which none of us had heard of. (她一个晚上都在谈论她最近的书,我们一个人都没有听说过那本书。)
[注解]
1、关系代词只能用that的情况:当先行词是指事物的不定代词(all, anything等),或先行词部分含有最高级,或含有序数词时,不能用其他的关系代词,只能用that. 如:All that Lily told me seems untrue. (Lily告诉我的话似乎不真实。) / Can you give me anything that has no sugar inside? (能不能给我点里面没有糖的东西?) / This is the first two-story bus that runs in our city. (这是第一辆运行于我市的双层公交车。)
2、关系代词在从句中作主语时一般用who(指人)、that(指物),而不用that指人或用which指物。 如:Do you know the woman who is weeping in the corner? (你认识那个在角落里哭泣的女人吗?) / Do not tell me any words that have nothing to do with me. (跟我无关的话,请一个字也不要说。)
3、关系代词作从句的宾语时,常用which或whom,较少使用that或who,而且,关系代词常常省略。如:Tom’s father was the first parent whom our teacher talked to. (Tom的父亲是我们老师第一个谈话的人。)
4、当关系代词紧跟在介词后面时,必须用which或whom,而当介词移到句尾时,则又可以使用that或who. 如:This is the room in which Miss Li once lived. (= This is the room Miss Li once lived in.) (这是李小姐曾经居住过的房间。)
(5) 主语从句:在句子中充当句子主语的从句叫主语从句。位于谓语动词之前。通常由that,whether以及疑问连词引导。一般情况下,常用it替代主语从句,而将主语从句移到句尾。如:When we should start is still a question. (我们该在什么时候开始还是个问题呢。)

⑥ 正确的英语语法复合句子怎么写
复合句,就是把简单句无法说清楚的东西用从句补充完整。要写好复合句版子掌握以下几权点;
1、要会写定语从句⑦ 英语的复合句怎么写
从句子结构上来说,句子有三种:简单句、并列句和复合句。简单句有一个主语或多个主语和一个谓语;一个主语和多个谓语。并列句是由并列连词连接的两个或多个简单句。复合句指的是含有两个或更多的主谓结构的句子,其中有一个(或更多)主谓结构充当句子的某一(些)成分,如主语、宾语、表语、定语、状语、同位语等。主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句都属于复合句。
一、状语从句:
状语从句 Adverbial Clause,从句用作状语称为状语从句。根据用途,状语从句可分为时间、地点、原因、条件、方式、让步、结果、目的等状语从句。
I. 时间状语从句

5) In case it rains, do not expect me. 如果下雨,就不要等我了。
6) He will do anything as(so) long as it is interesting. 只要好玩,他什么都愿意做。
V. 方式状语从句

Ships carry lifeboats so that people can escape if the ship sinks.
They wrote the notice in several languages so that foreigners could understand it.
We carved their names on the stone in order that people should always remember them.
They risk their lives so that/in order that they may support their kids.
二、定语从句
定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词有:who, whom, whose, that, which等。
关系副词有:when, where, why等
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)
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
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.
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。
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。
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。
5. 介词+关系词
1)介词后面的关系词不能省略。
2)that前不能有介词。
3) 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
6. as, which 非限定性定语从句
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。As一般放在句首,which在句中。
as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:
(1) as 引导的定语从句可置于句首,而which不可。
(2) as 代表前面的整个主句并在从句中作主语时,从句中的谓语必须是系动词;若为行为动词,则从句中的关系代词只能用which。
7. 先行词和关系词二合一
1)Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school. (what 可以用all that代替)
8. what/whatever;that/what; who/whoever
1)what = the thing which;whatever = anything
2) who= the person that whoever= anyone who
3) that 和 what
当that引导定语从句时 ,通常用作关系代词,而引导名词性从句时,是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从句, 用作连接代词,作从句的具体成分,且不能省略。
9. 关系代词that 的用法
1)不用that的情况
a) 在引导非限定性定语从句时。
b) 介词后不能用。
2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中,只用that,不用which。
b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。
c) 先行词有the only, the very修饰时,只用that。
d) 先行词为序数词、数词、形容词最高级时,只用that。
e) 先行词既有人,又有物时,只用that。
三、名词性从句:
在句子中充当主语、宾语、表语与同位语的句子分别叫做主语从句、宾语从句、表语从句和同位语从句, 这些统称为名词性从句。
(一)主语从句
在复合句中用作主语的从句叫主语从句。
A 为了强调主语从句的内容,可将从句置于句首
B 大部分主语从句都可以用it作形式主语
为了保持句子平衡,主语从句常用it作形式主语,将主语从句后置。用it作形式主语的主语从句结构有如下几种:
1、It is + 名词 + that从句
2、It is + 形容词 + that从句
3、It + 动词 + that从句
4、It is + 过去分词 + that从句
用形式主语it引导的主语从句相当多,有些已形成固定的语法和译法。常见的有:
It is said that... 据说……
It is reported that... 据报导……
It is well known that... 众所周知……
It is announced that... 据宣布……
It is believed that... 人们相信……
It is thought that... 人们认为……
It is understood that... 自不待言……
It must be pointed out that... 必须指出……
It must be admitted that... 必须承认……
(二)宾语从句
宾语从句 The Object Clause,在复合句中作主句的宾语,它属于名词性从句。它可以作主句谓语动词的宾语,也可以作介词的宾语。宾语从句以从句的句式来决定连接词。
宾语从句有四步曲
连接词: (也叫引导词)
语序: 从句的词序用陈述语序(主+ 谓)
时态: 主句的时态如果是过去时,从句的时态应以过去时为基础作相应的变化。
人称: 要根据句中的意义作相应的变化
连接词(引导词)
从属连词 that ,if ,whether
连接代词 who, whom, whose, which, what
连接副词 when ,where ,how ,why
1.如果陈述句作从句,连接词用that,在口语和非正式语体中常可省略that 。
2.特殊疑问句作从句,就用原来的特殊疑问词
3.一般疑问句作从句,连词用if或whether 在选择疑问句只用whether,记住这一结构:whether … or not 。
(三)表语从句
表语从句放在连系动词之后,充当复合句中的表语。
A 可接表语从句的连系动词
可接表语从句的连系动词有be, look, seem, sound, appear等。
B as, as if / though引导的表语从句
C because, why引导的表语从句
what引导的主语从句表示结果或名词reason作主语时,后面的表语从句表示原因时要用that引导,不宜用because。
D 使用虚拟语气的表语从句
在表示建议、劝告、命令含义的名词后的表语从句,谓语动词需用"should+动词原形"表示,should可省略。常见的词有:advice, suggestion, order, proposal, plan, idea等。
(四)同位语从句
同位语从句用于对前面的名词作进一步解释,说明名词的具体内容。同位语从句一般由that引导,但也可以由whether以及连接代词和连接副词引导。
A 同位语从句一般跟在名词的后面
同位语从句一般跟在名词fact, hope, idea, news, doubt, suggestion, information, opinion, decision, discovery, truth, promise, statement, problem, rule等后面。
B 使用虚拟语气的同位语从句
在一些表示“建议、命令、要求”的名词后的同位语从句中,谓语动词用"should + 动词原形",should可省略。
⑧ 英语语法讲解复合句
复合句指的是含有两个或更多的主谓结构的句子,其中有一个(或更多)主谓结构充当句子的某一(些)成分,如主语、宾语、表语、定语、状语、同位语等。主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句都属于复合句。
一、状语从句:
状语从句 Adverbial Clause,从句用作状语称为状语从句。根据用途,状语从句可分为时间、地点、原因、条件、方式、让步、结果、目的等状语从句。
I. 时间状语从句
时间状语从句表示时间,常用的关联词有when, until, as, after, before, once, since, as long as, whenever等等。
例: 1) When you cross a main road, you must be careful.
2) He went out to play football after he had finished his homework.
3) Wait until you are called.

1) If it snows tomorrow, we will build a snowman.
You'll be late, unless you hurry.
3) Suppose we are late, what will he say? (suppose从句必须放在主句之前) 我们如果迟到了,他会说什么?
4) In the event that our team wins, there will be a party.
5) In case it rains, do not expect me. 如果下雨,就不要等我了。
6) He will do anything as(so) long as it is interesting. 只要好玩,他什么都愿意做。
V. 方式状语从句

They risk their lives so that/in order that they may support their kids.
二、定语从句
定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词有:who, whom, whose, that, which等。
关系副词有:when, where, why等
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)
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
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.
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。
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。
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。
5. 介词+关系词
1)介词后面的关系词不能省略。
2)that前不能有介词。
3) 某些在从句中充当时间,地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。
This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
6. as, which 非限定性定语从句
由as, which 引导的非限定性定语从句,as和which可代整个主句,相当于and this或and that。As一般放在句首,which在句中。
as 和which在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:
(1) as 引导的定语从句可置于句首,而which不可。
(2) as 代表前面的整个主句并在从句中作主语时,从句中的谓语必须是系动词;若为行为动词,则从句中的关系代词只能用which。
7. 先行词和关系词二合一
1)Whoever spits in public will be punished here. (Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school. (what 可以用all that代替)
8. what/whatever;that/what; who/whoever
1)what = the thing which;whatever = anything
2) who= the person that whoever= anyone who
3) that 和 what
当that引导定语从句时 ,通常用作关系代词,而引导名词性从句时,是个不充当任何成分的连接词。宾语从句和表语从句中的that常可省略。What只能引导名词性从句, 用作连接代词,作从句的具体成分,且不能省略。
9. 关系代词that 的用法
1)不用that的情况
a) 在引导非限定性定语从句时。
b) 介词后不能用。
2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中,只用that,不用which。
b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。
c) 先行词有the only, the very修饰时,只用that。
d) 先行词为序数词、数词、形容词最高级时,只用that。
e) 先行词既有人,又有物时,只用that。
三、名词性从句:
在句子中充当主语、宾语、表语与同位语的句子分别叫做主语从句、宾语从句、表语从句和同位语从句, 这些统称为名词性从句。
(一)主语从句
在复合句中用作主语的从句叫主语从句。
A 为了强调主语从句的内容,可将从句置于句首
B 大部分主语从句都可以用it作形式主语
为了保持句子平衡,主语从句常用it作形式主语,将主语从句后置。用it作形式主语的主语从句结构有如下几种:
1、It is + 名词 + that从句
2、It is + 形容词 + that从句
3、It + 动词 + that从句
4、It is + 过去分词 + that从句
用形式主语it引导的主语从句相当多,有些已形成固定的语法和译法。常见的有:
It is said that... 据说……
It is reported that... 据报导……
It is well known that... 众所周知……
It is announced that... 据宣布……
It is believed that... 人们相信……
It is thought that... 人们认为……
It is understood that... 自不待言……
It must be pointed out that... 必须指出……
It must be admitted that... 必须承认……
(二)宾语从句
宾语从句 The Object Clause,在复合句中作主句的宾语,它属于名词性从句。它可以作主句谓语动词的宾语,也可以作介词的宾语。宾语从句以从句的句式来决定连接词。
宾语从句有四步曲
连接词: (也叫引导词)
语序: 从句的词序用陈述语序(主+ 谓)
时态: 主句的时态如果是过去时,从句的时态应以过去时为基础作相应的变化。
人称: 要根据句中的意义作相应的变化
连接词(引导词)
从属连词 that ,if ,whether
连接代词 who, whom, whose, which, what
连接副词 when ,where ,how ,why
1.如果陈述句作从句,连接词用that,在口语和非正式语体中常可省略that 。
2.特殊疑问句作从句,就用原来的特殊疑问词
3.一般疑问句作从句,连词用if或whether 在选择疑问句只用whether,记住这一结构:whether … or not 。
(三)表语从句
表语从句放在连系动词之后,充当复合句中的表语。
A 可接表语从句的连系动词
可接表语从句的连系动词有be, look, seem, sound, appear等。
B as, as if / though引导的表语从句
C because, why引导的表语从句
what引导的主语从句表示结果或名词reason作主语时,后面的表语从句表示原因时要用that引导,不宜用because。
D 使用虚拟语气的表语从句
在表示建议、劝告、命令含义的名词后的表语从句,谓语动词需用"should+动词原形"表示,should可省略。常见的词有:advice, suggestion, order, proposal, plan, idea等。
(四)同位语从句
同位语从句用于对前面的名词作进一步解释,说明名词的具体内容。同位语从句一般由that引导,但也可以由whether以及连接代词和连接副词引导。
A 同位语从句一般跟在名词的后面
同位语从句一般跟在名词fact, hope, idea, news, doubt, suggestion, information, opinion, decision, discovery, truth, promise, statement, problem, rule等后面。
B 使用虚拟语气的同位语从句
在一些表示“建议、命令、要求”的名词后的同位语从句中,谓语动词用"should + 动词原形",should可省略。
