高中名词性从句讲解与练习(包含答案)

名词子句名词子句对应名词，分别是主语、表语、宾语、同文语。因此，名词子句分为主语、表语、宾语、同位从句。(a)引导名词子句的连接词支架单词的意思子句中的作用That没有任何意义只有连接起作用，子句中没有任何句子成分起作用。一般可以省略，但在句子开头不能省略。If和whether意思是“是”，表示条款含义的不确定性。起连接作用，不作为条款中的任何句子成分关系代词：谁、what、which、whom、whose、whatever、whoever、Whomever，whichever有自己的意义起连接作用，在子句中，它充当主、表、空、属性等关系副词：When、where、why、how、however、whenever和wherever有自己的意义起连接作用，在子句中起副词的作用(b)主语子句1.主语从句在复句中用作主语。E.g. Who will go is not important。2.that在引导主语时不能省略。e . g . that he suddenly fell ill last week made us surprised。It作为格式主题，主题部分放在句子末尾。It系动词形容词that子句。necessary、right、likey、wrong、important、certain、clear.It系统动词名词that子句。a pity、a shame、a fact、no wonder.It be动词ed that子句。said、told、reported、suggested、considered.It特殊动词that子句。seem、turn out、appear、matter.e . g . it doesn t matter so much whether you will come or not .4.whether领导的主语可以放谓语，而if领导的主语不能放谓语，只能放句尾。whether the worked can be completed on time is doubt ful。it is doubtful whether/if the work can be completed。(c)剽窃1，表语从句在复合句中用作表语，位于系动词之后。e . g . the question was who could go there。2、引导标语子句的连词that有时可以存储。e . g . my idea is(that)we can get more comrades to help in the work。通常，引导标语子句不需要if。the question is whether we can reduce the cost of the product .4.其他连接方：as if、as though、because、as和like。it sounds as if/though he has been really ill。5.主语是reason:表语从句的连词不是that，why。the reason why he was un happy is that he has lost his keys。6.表语从句的家庭法。(d)宾语从句1，宾语从句在复合句中用作宾语。引导宾语从句的连词that一般可以省略。e . g . I hope(that)everything is all right。2、介词后的宾语从句，如果没有用which或if连接，则分别用what或whether写。e . g . I m interested in whether you ve finished the work.Im interested in what youve said。3，whether和if都可以推导出宾语从句，并且经常交换。但是以下情况不能互相交换。宾语从句是否定句的时候只使用if，不使用whether。E.g. I wonder if it doesnt rain。使用if会产生误会。使用whether。e . g . please let me know whether you want to go。把宾语从句的whether和or not直接连接起来，不能变成if；不用直接一起写，可以改写。e . g . I don t know whether or not the report is true。I don t know whether/if the report is true or not .介词后的宾语从句引向whether。Whether可以和不定式一起使用。Whether还可以推导主语、表语从句、appositive子句、让步状语从句等，上面的内容不能改为if。但是，在引导条件子句时，只能使用if而不能使用whether。e . g . it depends on whether we have enough time。They dont know whether to go there。Please come to see me if you have time。(e)同位素节同义句在句子中用作名词的同义词，一般在名词(例如news、fact、idea、suggestion、promise等)之后描述该名词的具体内容。1.if通常不引导appositive子句。引导同义词子句的连接词通常不会省略。e . g . I have no idea when he will be back。the fact that he had not said anything surprised everybody。Attributive子句和appositive子句之间的区别：A:that领导的两个部分的区别：(1)定语从句说明名词的性质、性质和来源。同义句说明名词表示的具体内容。(2)在attributive子句中，that充当组件，而在appositive子句中，that只是连接词，不能充当或省略组件，也不能被which代替。(3)同义词中的前导词通常包含信息，例如信息、新闻、事实、希望、problem、suggestion等。(.(4)判断方法：所有相同的语言子句可以更改为：The news/idea/thought is that。的结构，但不能进行属性子句。the news that our team won the game exited us all。=the news was that our team won the game。the news that the radio broadcast this morning is not true at all .B : who、whom、whose、when、where、why领导的两个部分的区别：指南的归属节是指前面先行词表示的人、事物、时间、地点、原因。在Appositive子句中，表问。I will cherish the time when I won the prize。I have no idea when he won the prize。练习：名词子句第一，判断以下哪个句子包含名词子句，并指出是什么条款。1.China is no longer what it used to be。2.the truth that the earth turns around the sun is known to all .3.it was snowing when he arrived at the station。4.how he persuaded the manager to change the plan is interesting to us all。5.the news that they had won the game soon spreadover the whole school .6.the news that you told me yesterday was really disappoiting。7.That is where Lu Xun used to live。8.he spoke as if he understand what he was taling about。9.do you remember the teacher who taught us English at middle school？10.I wonder why she refused my invitation。第二，用适当的连接词填空。1.I can t decide _ _ _ _ _ _ _ _ _ dictionary I should buy。2.that s _ _ _ _ _ _ _ _ _ _ he refused my invitation。3.I am very interested in _ _ _ _ _ _ _ _ _ _ _ _ he has improved his pronuncation in such a short time。4._ _ _ _ _ _ _ _ _ _ we need is more time。5.the fact _ _ _ _ _ _ _ _ _ _ _ shehad not said anything at the meeting surprised every。6._ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ they will meet has not been decided yet。7.please tell me _ _ _ _ _ _ _ _ _ _ you are waiting for。8.is that _ _ _ _ _ _ _ _ _ _ _ you are looking for？9.would you please tell me _ _ _ _ _ _ _ _ _ _ _ the nearest post office is？10.I don t know _ _ _ _ _ _ _ _ _ _ he will agree to the plan or not .三、选择填空：1.Do you see _ I mean？A.that B. /C. howD。what2.tell me _ _ _ _ is on your mind。A.tharb.whatc.which d.why3.we must stick to _ _ _ _ _ we have agreed on。A.whatB .thatC ./D. how4.let me see _ _ _ _ _ _ _ _。A.that can I repair the radiob。whether I can repair the radioC.I can repair the radiod . whether can I repair the radio5.keep in mind _ _ _ _ _ _。A.that the teacher saidb。what did the teacher sayC.that did the teacher sayd。what the teacher said6.could you advise me _ _ _ _ _ _ _？A.which book should I read firstb。what book should I read firstC.that book 1 should read firstd .which book I should read first7.He was criticized for _ _ _。A.he had done ITB。what he had done c . what had he done d . that he had done it8.would you kindly tell me _ _ _ _ _？A.how can I get to the Beijing railway stationB.how I can get to the Beijing railway stationC.where can I get to the beijin railway stationD.whether ecan I get to th
