名词性从句复习课件.ppt

,Noun Clause,一. 什么叫“名词性从句”？,名词性从句在功能上相当于名词,主语,His job is important.,What he does is important.,表语,This is his job.,This is what he does every day.,宾语,I dont like his job.,I dont like what he does every day.,同位语,I dont know about the man, Mr. White.,I dont know about the fact that he is a teacher.,相关概念,1.名词的句法作用：名词在句中主要作 主语,宾语,表语和同位语。 2.名词性从句： 在英语的句子结构中，本来该由名词充当的主 语、宾语、表语和同位语，由一个句子来充当,这个句子就叫: 名词性从句。,宾语从句 Object Clause,表语从句 Predicative,主语从句 Subject Clause,同位语从句 Appositive Clause,名词性从句 Noun Clause,主语从句,同位语从句,表语从句,宾语从句,1.When we will start is not clear. 2.Mrs Black wont believe that her son has become a thief. 3. My idea is that we should do it right now. 4.I had no idea that you were her friend.,主语从句,宾语从句,表语从句,同位语从句,二、 判断下列从句类型,引导名词性从句的连接词,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.主语从句：在句中充当主语成分,1). That he will succeed is certain . 2) Whether he will go there is not known . 3) What he said is not true . 4) Where he hid the money is to be found out . 5) How we can help the twins will be discussed at the meeting. 6) Its certain that he will succeed .,使用主语从句的几点注意事项：,1.有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把that的主语从句置于句末。单个主语从句常视为单数。常用it作形式主语的句型如下： 1）It + be + 形容词 + that从句 2）It + be + 名词 (hope, pity, wonder, etc.)+ that从句 3）It + be + 动词的过去分词 + that从句 4）It + 特殊动词(常为不及物动词) + that 从句 eg. It happened to me that I had been away when he called. It really matters that you havent turned up.,2.另外，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, surprising, unthinkable, unbelievable, incredible, etc.) that It is suggested (advised, ordered, required, insisted, demanded, requested, proposed, desired, etc.) that,练习:用it充当形式主语,1.That we shall be late is certain. - 2. That the earth is round is known to all. - 3. That you missed the chance is a pity. -,Its known to all that the earth is round.,Its a pity that you missed the chance.,Its certain that we shall be late.,1. _ he made an important speech at the meeting was true.

A. whether B. that C. what D. when,2. 宾语从句：在句中充当宾语成分（ 可以作谓语动词、介词、不定式等非谓语动词的宾语） 连词：that, whether，if （ that 常可省略） who, what, which, whoever, whatever, when where why how,1).

A. whether B. how C. where D. which,宾语从句可以用it（作形式宾语） 来替换的句型为： 主语谓语itAdj/N从句如： I think it necessary that we have the meeting,找出下列句子中的错误，并总结出规律： I think that worthwhile that we spent so much money on these books. 2. That is hard to decide when and where we will held our sports meeting. 3. Everybody considers it impossible which he wants to finish the job in such a short time. 4. It doesnt matter that you will come or not.,it,It,that,whether,规律:主语从句和宾语从句在适当的情况 下可以借助 “it” 而后置。,3. 表语从句：从句在句中充当表语成分，一般放在连系动词之后, 对主语进行解释说明。,1.Thats _ the Party called on us to do. A. why B. what C. how D. that 2. The reason is _ he is unable to operate the machine. A. because B. why C. that D.
