高考英语第二轮热点专题复习——名词性从句（最新）考情分析名词性从句是历年高考的重点和难点也是热点。
名词性从句相当于名词，可用作主句的主语、表语、宾语和同位语。
因此，名词性从句分为主语从句、表语从句、宾语从句和同位从句。
引导名词性从句的连接词有：连接代词：who, whose, whom, what, which，有词义，在从句中担任成分，如主语、表语、宾语、或定语等；连接副词：when, where, why, how，有词义，在从句中担任成分，作状语；连接词：that, whether, if, as if，if (whether), as if虽有词义，但在从句中不担任成分；that 无词义，在从句中不担任成分，有时可省略。
名词性从句重点与难点：一、that从句作主语和宾语时，常用it作形式主语，将从句放在句末e.g. It doesn’t matter so much whether you will come or not.She has seen to it that all the children are well taken care of.二、that引导名词性从句的省略情况1、that引导主语从句、表语从句、同位语从句时，不能省略。
e.g. That he suddenly fell ill last week made us surprised.2、that引导宾语从句时一般可省略，但在以下几种情况中不能省略。
1）当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时不能省略；2）当that 从句与另一名词性从句并列作宾语时不能省略；3）当that作介词宾语时不能省略。
e.g. He judged that, because he was a child, he did not understand wineEveryone knew what happened and that she was worried.The reason lies in that she works harder than the others do.三、名词性从句中的语序名词性从句中一律使用陈序语气。
高中英语名词性从句详细讲解一.名词性从句考查的焦点主要有以下六方面1. 考查名词性从句的语序问题2. 考查引导词that与what的区别3. 考查it在名词性从句中作形式主语和形式宾语的用法4. 考查whether与if的区别5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别6. 考查名词性从句的虚拟语气问题二.名词性从句的含义及连接词名词性从句的含义:在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、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四类：1. that（无含义，不充当成分）2. whether, if（有“是否”的含义，但不充当成分）3. 连接代词：what, whatever, who, whoever, whom, whomever,whose, which,whichever.（在从句中做主语、宾语、表语和定语）连接副词：when, whenever,where,wherever, how, however,why（在从句中做状语）4. as if,as though,because（不充当成分，在名词性从句中只引导表语从句）三. 四类名词性从句语法要点1.主语从句在整个句子中用作主语的从句叫主语从句。
What he wants to tell us is not clear.他要跟我们说什么，还不清楚。
It is known 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。
it作形式主语：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，而把主语从句置于句末。
It is clear that he is innocent in the accident.很明显，他在这场事故中是无辜的。
名词性从句一．名词性从句基本概念：在句子中起名词性作用的从句叫名词性从句。
Peter is interesting. What Peter said is interesting.主语主语从句I know Peter. I know that Peter is lovely.宾语宾语从句This is Peter. This is where Peter lives.表语表语从句A lovely teacher,Peter,is here.同位语The news that we won the game is exciting.同位语从句EG: I don’t know whether we will go out.二．名词性从句连接词的选择You may borrow which book you like.Whose watch was lost is known.三．主语从句1.定义：名词性从句做主语。
2.连接词That the earth moves around the sun is known to all.Whether we will go picnicing tomorrow depends on the weather.Who stands there is my father.2.用it作形式主语。
It be + 形容词/名词/过去分词+that从句It is a pity that he didn’t win the game.It is well known that the earth runs around the sun.EX：1.____we are invited to the concert this evening is good news to us.2.____we need is more time.3.__will come to have dinner is not known.4.It is common knowledge ____the whale is not a fish.5.It is known ____ he has agreed to my plan.四.宾语从句1.定义：名词性从句作宾语。
专题13 【名词性从句】解题指导·触类旁通寻方法，求策略，掌握“套路”第一步：识别名词性从句的种类1．首先确定主句的谓语动词，确定主句的主谓结构；2．分析从句在主句中所充当的成分，确定从句所属类型：主语从句、宾语从句、表语从句、同位语从句。
第二步：分析从句结构，确定从句引导词确定从句的结构和意义是否完整，结合句意填写适当的连接词。
1．若从句结构完整，用从属连词：陈述事实用that；表示疑问“是否”用if或whether；2．若从句缺少主语、宾语、表语或定语，则考虑用连接代词；3．若从句缺少状语，则用连接副词。
另外，还需注意一些特殊的引导词(if, whether, because, as if等)的用法及that引导同位语从句与定语从句的区别。
技巧1 分析句子成分①缺少主语、宾语、表语：用连接代词what、 who、 whom、 which、 whatever等。
②缺少状语(结合句意判断)：用连接副词where(表地点)、 when(表时间)、 how(表方式)、why(表原因)等。
③不缺成分，句意不完整，缺少“是否”：用if/whether。
④不缺成分且句子意义完整：用that。
技巧2 结合句意和引导词的本义解题有些引导词在句中有很鲜明的意义，如if“是否”；whoever “无论谁”；whatever “无论什么”；whichever “无论哪一个(在范围中选择)”；because“因为”；why “为什么”等。
结合句意和语境，不难解决这类试题。
①that没有词义，也不作任何成分，当从句意义完整，不缺任何成分时用that。
②what在从句中表示“……的(东西)”，在从句中充当主语、宾语、表语、定语等成分。
考点突破·针对提能明考点，攻重难，有效提升考点一、主语从句1．主语从句的引导词引导词作用that, whether, if 只起连接作用，不在从句中作成分，但一般不可省略。
名词性从句在英语中，句子可分为简单句和复合句，复合句即常说的“从句”。
由一个主句和一个（或几个）从句构成的句子叫主从复合句。
在复合句中，我们是根据从句在整个句子中所充当的成分来给复合句命名的。
如：主语从句，宾语从句，定语从句，等等。
所有的复合句中，“主语从句，宾语从句，表语从句，同位语从句”，他们的从句有名词性特征，因此合称为“名词性从句”。
名词性从句的引导词引导词是否在名词性从句中充当成分的情况充当成分：连接代词： what, which, who, whom, whose，whatever, whoever, whichever,不从当成分：连接副词： when, where, why, how, however只起连接的作用：that, if/whether, because（that引导的名词性从句，既不作任何成分，也无意义，只是表明从句是一种陈述语气，起个连接作用；if不能引导表语从句和同位语从句，if引导主语从句时不能置于句首，if引导宾语从句时，只能置于及物动词后，不能置于介词后；because只能引导表语从句）㈠主语从句（用作主语的从句叫做主语从句）1．that从句作主语That引导的主语从句可位于句首直接作主语;也可以位于句末，用it作形式主语;① That we are invited to a concert this evening is a piece of good news for us.②It is obvious that the earth is round.2．whether/if（是否）从句作主语同样可放句首或句末，但放句首只能用whether，不能用if.①Whether we shall go or stay ,is uncertain.②It was not known whether/if he would ask.3． whoever, whichever, whatever, however引导主语从句只能放句首。
高考英语名词性从句讲解一、概念：名词性从句相当于名词词组，在复合句中起名词性作用。
分类：主语从句、表语从句、宾语从句和同位语从句。

1.that 引导的主语从句①句首That a round-trip to Mars would take more than a year and a half is estimated.That he misunderstood me is obvious.That引导主语从句，放句首，不做任何成分，不可省略。
②用形式主语it来引导句子A. that引导主语从句放句首时，有时会为了避免头重脚轻，保持句子平衡，常用it做形式主语，把真正的that引导的主语从句放句后。
It is strange that he made no answer.It is known to all that the earth is round.B. 用it做形式主语的主语从句结构注意：i. It作形式主语和it引导强调句的比较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。
