1、高考英语第二轮语法专题复习八名词性从句知识要点：1、熟悉并掌握各个连接词、关系代词和连接副词的用法。2、熟悉并掌握复合句即名词性从句（主语从句、宾语从句、表语从句、同位语从句），定语从句和状语从句。什么叫复合句由一个主句和一个或一个以上的从句构成的句子叫复合句。在复合句中主句是全句的主体，从句是全句的一个成分，不能独立。从句通常是用关联词来引导的。在这里关联词还起联系从句和主句的作用。主从复合句（Complex Sentences）一、从句的种类：主语从句（Subject Clauses）1、名词性从句表语从句（Predicative Clauses）Noun Clauses宾语从句（Obje
2、ct Clauses）同位语从句（Appositive Clauses）2、定语从句（Attributive Clauses）3、状语从句（Adverbial Clauses）注：以it作形式主语，把主语从句后置的常用的句型有：（1）It + be + 形容词 + that从句（2）It + be + 名词词组 + that从句（3）It + be + 过去分词 + that从句（4）It seem, happen等不及物动词 + that从句二、常用的关联词1、从属连词 that（无词义）；whether是否；if假如，是否 although(though)虽然；because因为 when

4、可省去词whether Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。 主语从句中只能用whether不可用if。主语连接代词whowhatwhichwhatever What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。 主语从句放在句首，句子常显得笨重，因此一般从句连接副词whenwherewhyhow It is kn
5、own to us how he became a writer. 我们都知道他是如何成为一名作家的。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。把它移到句子后面，前面用引导词“it”来作形式主语。2、宾语从句：种类关联词例 句说 明陈述意义that I believe(that) he is honest. 我相信他是忠诚的。We must never think(that) we are good in everything while others are goo
6、d in nothing. 我们决不能认为自己什么都好，别人什么都不好。 that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。宾疑问意义ifwhether I wonder whether he will come or not. 我想知道他来还是不来。 Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。 I dont know if(whether) it is interesting. 我不知道它是否有意思。 He doesnt care if it
7、 isnt a fine day. 他不在乎天气是否好。 whether常与or not连用，不能用if代替。 作介词宾语要用whether不能用if。从句是否定句时一般用if引导。语特殊疑问意义who, whom,which,whose,what, when,where, why,how,whoever,whatever, whichever Please tell me what you want. 请告诉我你需要什么？ She always thinks of how she can work well. 她总是在想怎样能把工作做好。 She will give whoever need
8、s help a warm support. 凡需要帮助的人，她都会给予热情的支持。 宾语从句作及物动词宾语也可做介词的宾语。从注1 We must make it clear that anyone who breaks the law will be punished. 我们必须认清无论谁违反了法律都要受到惩罚。 如果宾语从句后面有宾语补足语，则用it作形式宾语，将从句后置。句注2 We dont think you are here. 我们认为你不在这。 I dont believe he will do so. 我相信他不会这样做。 think, believe, imagine, s
9、uppose等动词引出的宾语从句，要将从句中的否定形式，移动主句中。3、表语从句：种类关联词例 句说 明表连词thatwhetheras if The problem is(that) they cant get here early enough. 问题是他们不能很早到达这里。 It looks as if its going to rain. 看起来天要下雨。 在非正式的文体中that可以省去。语从连接代词whowhatwhich Thats just what I want. 这正是我想要的。 The question is who(which of you) will be the n

12、r, doubt, word, proof， belief, story等。名词性从句包括四种从句即主语从句、表词从句、宾语从句和同位词从句。名词性从句的特点：that 、who、 whom、 what 、whether及 when、 where引导名词性从句时必须是陈述句词序：1、主词从句：That light travels in straight line is known to all .(That 引导主语从句不可省） When the plan is to take off hasnt been announced 主语从句通常以it 做形主语出现It was my fault t

14、句 时态一定往前推移，不可出现现在时或现在完成时。The teacher told us that Tomo had left us for America 4、同位语从句注意与定语从句区别，同位语从句对前一名词做补充说明，在 从句中无语法位置，而定语从句所修饰词在从句中占一语法位置如：The idea that one can do the work without thinking is wrong( 同位idea在从句中 无位置，而从句只是具体说明idea的内容）。The idea that you put forward at the meeting is wrong (定语从句，id
