名词性从句有答案

辨别下列名词性从句的类别：1.How the book will sell depends on its author.2.John said that he was leaving for London on Wednesday.3.The fact is that he has not been seen recently.4.The fact that he has not been seen recently disturbs 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.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, why1。

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。

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 didn’t go to see the film.It doesn’t interest me whether you succeed or not.2. what 与that 在引导主语从句时的区别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) _what you said yesterday is right.2) __That she is still alive is a good thing.It is a good thing that she is still alive.二．宾语从句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. 作动词的宾语(1) 由that引导的宾语从句(that 通常可以省略), 例如：I heard that he joined the army.(2) 由what, whether (if) 引导的宾语从句，例如：She did not know what had happened.I wonder whether you can change this note for me.(3) 动词＋间接宾语＋宾语从句。

例如：She told me that she would accept my invitation.2. 作介词的宾语，例如：Our success depends upon how well we can cooperate(合作）with one another.3. 作形容词的宾语，例如：I am afraid (that) I’ve made a mistake.I am sure (that) he will win the game.4. it 可以作为形式宾语it 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。

例如：We thought it good news that the fog had finally gone.5. 否定的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：我认为这件衣服不适合你穿。

I don’t think the dress fits you we ll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 whether/how we can make good preparation in such a short time.2) This is why we can’t get the support of the people.3) But the fact remains that we are behind the other classes.4) The reason why he is late for school is that he missed the early bus.四．同位语从句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。

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 king’s 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.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.3. 同位语从句与定语从句的区别(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。

(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述它的性质或特征；同位语从句是名词性的，其功能是对名词进行具体内容的补充说明。

例如：1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。

）（第一个that引导的从句是定语从句，that在从句中作宾语）2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。

）（同位语从句，that在句中不作任何成分）whether 与if 均为“是否” 的意思。

但在下列情况下，whether 不能被if 所取代：1.主语从句Whether he will come is unknown.2. 表语从句，如：The question is whether you should accept it.3. 同位语从句，如：The question whether he’ll attend the meeting is not decided.4. 从句作介词的宾语，如：I’m not interested in whether they’ll go or not.It depends on whether we have got enough money.5. 直接跟不定式连用，如：She hasn’t decided whether to go or not.用if 或whether 填空1. I don’t know __________ I’ll be free tomorrow.2. I don’t know _______ or not I’ll be free tomorrow.3. The question is ______ this book is worth writing.4. It depends on ______ we willhave enough money.5. ______ they can do it matters little to us.6._______ you are not free tomorrow , I’ll go without you.1.whether/if2.whether3.whether4.whether5.Whether6.If（I）试比较下面两个例句:1.The suggestion that he raised at the meeting is very good.（that引导定语从句, 作宾语, 可以省略）2.The suggestion that the students should have plenty of exercise is very good.（that引导同位语从句,在从句中不担当任何成分，但不可以省略）辨别下列从句是定语从句还是同位语从句1.We heard the news that our team had won.2.We must face the fact that we had spent all our money.3. The news that he told me yesterday was false.4. I have no doubt that he will come soon.5. The fact is that we have spent all our money.翻译以下句子，并指出带下划线的从句属于名词性从句中的哪一种。
