英语中的主语从句、定语从句、宾语从句以及表语从句的详细总结

Answer 1

1.主语从句 1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。常见的句型有： *It is a fact\a pity\a question\good news that... *It seems\appears\happened\has turned out that... *It is clear\important\likely\possible that... *It is said\reported\estimated\has been proved that... It is said that comic books create a connection between people of the same generation. It seems that the performance is very useful. 2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。 What we lack is experience. 3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。 How the plan is to be carried out should be discussed again. I did know why I felt like crying. 2.宾语从句 1）宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。 *I promised that I would change the situation. *All this is different from what American young people would say about friendship. *He is certain that watching so much television is not good for children. *This article is well-written except that it is a bit too long. 2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。 He has made it clear that he would not change his mind. 3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。 He didn't think that the money was well spent. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because. Perhaps the most important thing to remember is that there is no one common type of life in America. The reason why so many people died there is that there were not enough food supplies. It looks as if successful international cultural communication will make the world smaller. 4.同位语从句 同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。 She finally made the decision that she would join the fashion show. I had no idea how many books I could borrow at a time. The news came that their team had won the championship. 5.定语从句 定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。 *限制性定语从句 限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。 The computers and cables which make up the Internet are owned by people and organizations. Those who live alone or who are sick may have trouble in getting close to other people. The girl whose parents died in an accident is living with her grandmother. 1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。 That is all that I've heard from him. He's the first person that I'm going to interview this afternoon. 2)关系代词的省略 在从句中作宾语的关系代词常可省略。关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。 This is one of those things with which we have to put up. This is one of those things (which\that) we have to put up with. 3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。 Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings. No one knows the reason why(=for which) he was so angry that day.*非限制性定语从句 非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。 Every object has a gravitational pull,which is rather like magnetism. *“介词+which\whom\whose”引导的定语从句 “介词+which\whom\whose”可引导限制性定语从句，也可引导非限制性定语从句，该结构中介词的选择取决于从句谓语动词的固定搭配，或先行词的习惯搭配。 This is the computer on which he spent all his savings It is written by a person with whom we are all familiar. *as引导的定语从句 as引导的定语从句主要用于“such...as”及“the same...as”的结构中，代替先行词是人或物的名词。as引导非限制性定语从句时，代替整个主句，从句可位于主句之前、之后或中间。 These are not such problems as can be easily solved.(as代替先行词problems) As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语) 6.状语从句 *时间状语从句 引导时间状语从句的从属连词和词组有： 1）when,whenever,while,as,after,before,since,till,until,once等。 We have learnt quite a lot about it since we came here. 2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。 As soon as I sent an e-mail message,I received positive responses. The moment he heard the good news,he jumped with joy. *地点状语从句 引导地点状语从句的连词是where,wherever. Wherever she went,she took her little daughter with her. *原因、结果和目的状语从句 1）引导原因状语从句的从属连词有：because,as,since,now(that),seeing that,considering that,in that等。 Considering that he is a freshman,we must say he is doing well. 2)引导结果状语从句的连词有：so...that,such...that,so that,that,so等。 Mickey Mouse is so attractive that the children are reluctant to leave. 3)引导目的状语从句的连词有：so that,in order that,for fear that,lest等，从句常使用may,might,can,could,would等情态动词。 We got up early this morning so that we could catch the first bus to the railway station. *条件和让步状语从句 1）引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。 As long as you have the right equipment,you can use a telephone line to transmit computer data. 2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构，具有强调意义。其结构为“形容词（副词、动词、名词）+as+主语+谓语”。 No matter what you may say,I would not change my mind. Young as he is,he is quite experienced in this work.(=though he is young) Child as he is,he can speak English fluently.(=though he is a child) *方式状语从句 引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中，谓语动词常用虚拟语气，表示与事实相反。 The young man made the experiment just as the teacher had taught him. Everything went on as usual as if nothing had happened.

Answer 2

先说定语从句吧 一 、正确区分关系代词that引出的定语从句功能强，除不能作定语(用whose)外，其它几个功能都可用that。但命题角度主要以that与which指物时的区别为重点进行命制。例如：（1）——Do you have anything in mind _________ you’d like for supper?——Well, _________ is OK with me.A. that ; anything B. which ; everythingC. what ; whatever D. where ; something 选A。（2）The wrong you've done him is terrible, for ______ you should make an apology to him, I think.A. this B. which C. what D. that 选B。 二 、正确区分关系代词(that或which)与关系副词when(表时间)、where(表地点)、why(表原因)。重点根据定语从句中所缺成分（即关系词在定语从句中作状语时，使用关系副词when (on which); where(in which); why(for which)；在定语从句中作作主语、宾语或表语时，使用that或which。）来确定是用关系代词还是关系副词，绝不能因先行词是时间名词就用when，是地点名词就用where，是reason就用why来确定。因此，认准先行词只是选择关系词的一个方面，更重要的是看其在后面定语从句中充当什么句子成分例如：（3）He should stand near the stage ________ he could watch and follow the play.A. where B. when C. that D. there 选A。（4）Do you think the reason _______ he gave is believable.A. for which B. which C. why D. what 选B。（5）We are living in an age _______ many things are done on computer.A. which B. that C. whose D. when 选D。 三 、当先行词在定语从句中作主语时，应注意主谓语的一致性及被动语态问题。尤其要注意在考题中不用定语从句，而是用分词短语作定语。例如：（6）The first textbooks ______ for teaching English as a foreign language came out in the 16th century.　 A. having written　 B. to be written　　 C. being written　 D. written 选D。四 、定语从句中不能再重复与先行词有关的代词或副词。必须牢记定语从句中关系词已经替代先行词并且在定语从句中已经充当其成分，故不能再用相关的代词或副词。例如：（7）He made another wonderful discovery, _______ of great importance to science.A. which I think it is B. which I think isC. which I think it D. I think which is 选B。（8）This is the hospital _____ they visited last year and is the one _____ I worked in five years ago．A．that；where B．where；thatC．where；where D．that；that 选D。（9）There are dirty marks on her trousers ________ she had wiped her hands.A. that B. which C. where D. when 选C。 五 、对介词后接关系代词而不接关系副词的考查；当关系代词作介词宾语，且该介词不是和从句的谓语动词构成固定短语时，介词可以提前，这样就出现"介词+关系代词"。先行词指物，用"介词+which", 指人则用"介词+whom", 且两个关系代词均不能省略，介词的选择要遵循两个原则：1.根据定语从句中谓语动词与先行词的搭配内容而定。 2.根据先行词特殊用法而定。例如：（10）This flower doesn't do well in soil other than the one_____ it has been specially developed．A．for which B．that C．of which D．where 选A。（11）Anyway, that evening, ____I will tell you more about later, I ended up staying at Rachel's place.A. when B. where C. what D. which 选D。 六、 关系代词as的考查。关系代词as引导限制性定语从句时既可指人又可指物。它只能替代由such，the same等修饰的先行词；as引导非限制性定语从句时，可放于句首，句中或置于句尾，而which则只能置于主句之后。但如果定语从句为否定句或表示否定意义，使用which。As引导的定性定语从句有"正如"之意，而which引导的没有。例如：（12）Our teacher set us such a difficult maths problem _____ we could not work out.A. that B. which C. as D. even 选C。（13）Carl said the work would be done by October , _______ personally I doubt very much.A. it B. that C. when D. which 选D。（14）________ is reported in the newspaper , talks between the two countries are making progress.A. It B. As C. That D. What 选B。 虽然定语从句的结构和用法比较复杂，但只要从定语从句的形式上、结构上和用法上来分析理解和比较，就一定就能把握定语从句的用法。
