名词性从句思维导图易考易错点总结名词性从句包括主语从句、宾语从句、同位语从句和表语从句。

考查的要点主要是连接代词和副词的正确使用、主语和谓语的语序、双重连接词以及特殊句型的使用等。

具体包括：1．考查名词性从句的连接词。

如：有词义的连接代词包括who, whose, whom, what,which ；连接副词有when, where, why, how ；从属连词有that, whether, if, as if ；that无词义，在从句中不作成分，有时可省略。

2．考查名词性从句的语序和时态。

3．考查it 作形式主语、形式宾语的情况。

如： (1)It ＋be ＋形容词(necessary, important, obvious 等)＋that 从句； (2)It ＋be ＋过去分词＋that 从句；(3)It ＋be ＋名词(a surprise, a fact, a shame, an honour 等)＋that 从句；(4)It ＋不及物动词(appear, happen 等)＋that 从句。

4．考查名词性从句中的虚拟语气。

如：(1)It is/was ＋essential/important/natural …＋that …；(2)It is/was suggested/demanded/wished/desired …＋that …等。

5．考查what 引导名词性从句时的语义功能和语法功能。

如：what ＝the thingthat/anything that ；what ＝the place that ；what ＝the time that ；what ＝the person that等。

6．考查whoever ，whatever ，whichever 引导名词性从句时的语义功能和语法功能。

七大常考考点: 1.that \ what \ which; 2.it 形式主语、宾语的用法; 3.语序问题; 4.同位语从句和定从的区别; 5.what \ whatever … 6.if\whether; 7.虚拟语气问题;五、相关习题集中练习一. 相关概念1. 名词：表示人或事物的名称的词2. 名词的句法作用：名词在句中主要作___,_____,表语和______。

3. 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____来充当,这个句子就叫:名词性从句。

二、名词性从句的种类1. When we will start is not clear. ______从句2. Mrs. Black won’t believe that her son has become a thief. _____从句3. My idea is that we should do it right now. ______从句4. I had no idea that you were her friend._______从句三、常见引导词：1）连接词：that, whether, if （不充当从句的任何成分）。

从属连词that 只引导，本身无意义，仅起__作用。

（引导宾语从句时可省，但是如果是并列的多个宾语从句，只能省第___个）That he likes you is very obvious. 很显然他喜欢你。

2）连接代词who, whom, what, which, whoever, whatever, whichever 等，均有各自的意义，在从句中作主语、宾语、定语等。

如： 同位语是对前面的名词或代词做进一步的解释，通常由名词、数That’s why she wanted to leave. 这就是她想离开的原因。

When we arrive doesn't matter. 什么时候到没有关系。

Tell me which one you like best. 告诉我你最喜欢哪一个。

3）连接副词where, when, how, why等，有意义，在句中作状语The question is how we should carry out the plan. 问题是怎样执行这个计划。

When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。

Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜4）从属连词if, whether（是否）(if只能引导动词、形容词之后的宾语从句)1. ______ he said has nothing to do with you.2. ______we’ll start tomorrow will be told soon.3. ______ he did such a thing satisfied me.4.______ we can protect cultural relics needs to be discussed.四．四大从句讲解1. 主语从句作句子____语的从句叫主语从句。

主语从句通常由从属连词___，whether，if 和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。

that在句中无词义，只起___作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。

如：____ 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 ____ he became a writer. 我们都知道他是如何成为一名作家的。

_____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。

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。

主语从句后的谓语动词一般用__数形式。

常用句型如（1）It + be + 名词+ that从句（a pity,a shame,a fact,a wonder,an honor, no wonder,a surprise）如：你考试失败了真是遗憾_____________________________（2）It + be + 形容词+ that从句（clear，important，necessary，probable，possible）It is certain that she will do well in her exam. （3）It + be + 动词的过去分词+ that从句(said, reported, thought, hoped, believed, known) coral reefs-珊瑚礁如:据报道，珊瑚礁正遭受破坏。

________________________________________ （4）It + 不及物动词+ that 从句（seem, happen, appear）如：碰巧那天我出去了。

______________________________________________ 另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, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…练习题：(1) ____ he will come is certain.(2) _____she is coming or not doesn’t matter too much.(3) ____ surprised me most was to see some of the village people seated on the benches at the end of the room.(4) _____ team will win the match is a matter of public concern.(5) ____ she has gone is not known yet.1. ____is known to all, Taiwan is only part of China.2.
