everyone in his office.,5.,He will talk to us about,what he saw in U.S.,6.,It is impossible,that I go and attend the meeting,.,主语从句,宾语从句,表语从句,同位语从句,宾语从句,主语从句,That/wh-clause,+v+,主语从句,S+be/link.v+,that/wh-clause,表语从句,S+vt+,that/wh-clause,宾语从句,S+vi+prep+,wh-clause,宾语从句,名词从句又可分别称为,主语从句、宾语从句、表语从句,和,同位语从句。,引导名词性从句的连接词可分为三类：,连接词：,that,whether,if,连接代词：,what,whatever,who,whoever,whom,whose,which.,连接副词：,when,where,how,why,1。that只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义，,宾语从句,中可省略,2。不充当介,宾,3。引导主语从句、,表语从句,和同位语从句,that不可省略。,4.,that whether,if,as if,as though（,以上在从句中均不充当任何 成分,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,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。例如：,It is a pity that you didnt go to see the film.,It doesnt interest me whether you succeed or not.,另注意在主语从句中用来表示,惊奇、不相信、惋惜、理应如此,等语气时，谓语动词要用 虚拟语气“(should)+do”，常用的句型有：,It is necessary(important,natural,strange,etc.)that,It is suggested(requested,proposed,desired,etc.)that,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)_you said yesterday is right.,2)_she is still alive is a good thing.,It is right what you said yesterday.,It is a good thing that she is still alive.,What,That,2.what 与that 在引导主语从句时的区别,主语从句中的“主谓一致”：,1.主语从句通常被看作一个整体,主句的谓语动词用单数形式.,That they will come _certain.,2.What 引导主语从句时,主句谓语动词的单复数由表语的单复数决定.,What he wants _these books.,What he wants _some water.,3.注意,is,are,is,1_in the regulations that you should not tell other people the pass word of your e-mail account.(2005上海),A.What is required B.What requires,C It is required D.It requires,2.The Foreign Minister said,“_ our hope that the two sides will work towards peace.”(2006 北京),A.This B.There is C.That is D.It is,3.After Yang Liwei succeeded in circling the earth,_ our astronauts desire to do is walk in space.(2004 上海),A.where B.what C.that D.how,Exercises,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.She did not know,what had happened,.,2.,Our success depends upon,how well we can cooperate with one another.,3.,I am afraid,(that)Ive made a mistake,.,宾语从句,(作动词的宾语),(作介词的宾语),(作形容词的宾语),注意1：在,demand，order，suggest，decide，insist,desire,request,command,doubt,等表示,要求、命令、建议、决定,等意义的动词后，宾语从句常用“（should）+动词原形”。,I insist that she(should)do her work alone.我坚持要她自己工作。,The commander ordered that troops(should)set off at once.司令员命令部队马上出发。,2.用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：,a.引导,主语从句,并在,句首,时；b.引导,表语从句,时；c.引导从句作,介词宾语,时；d.从句后有“,or not,”时；e.后接,动词,不定式,时。,Whether there is life on the moon is an interesting question.,The question is whether she should have a low opinion of the test?,Everything depends on whether we have enough money.,I wonder whether he will come or not.,Can you tell me whether to go or to stay?,3.宾语从句中的“时态呼应”与“否定转移”,若主句谓语动词为,think,consider,suppose,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：,He,told,me that he _ his job.,(,已经完成了工作),时态呼应,否定转移,我认为他不会来这里.,I think he wont come here.(),I dont think he will come here.(),had finished,注意,4.宾语从句中用it作形式宾语,We think it,our duty,that we should help others.,注意：如果主句中有形容词或名词作宾语补足语时，一般用it来作形式宾语，把从句放在宾补后面。,我发现他两天之内完成工作是不可能的.,I find it,impossible,that he can finish the work in two days.,Exercises:“it”作形式主语或形式宾语：,1.I hate _ when people talk with their mouths full,A.it B.that C.these D.them,2.I feel _ strange that he should be so careless.,A./B.it C.that D.how,3.It worried her a bit _ her hair was turning grey.,Awhile B.that Cif Dfor,4 Will you see to _ that the luggage is brought back?,A.weB.yourselfC.itD.them,A,B,B,C,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。另外，常用的还有the reason is that 和It is because 等结构。例如：,1)The question is _ we can make good preparation in such a short time.,2)This is _ we cant get the support of the people.,3)But the fact remains _ we are behind the other classes.,4)The reason _ he is late for school is _ he missed the early bus.,whether/how,why,that,why,that,四同位语从句,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 kings 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.,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。,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.,同位语从句和,定语从句,的区别：,that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。,I had no idea that you were here（that引导同位语从句，不能省略）,Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）,Exercises,1.Doris success lies in the fact _ she is co-operative and eager to learn from others.(2006
