高考英语名词性从句知识点一、that从句1、主语从句that从句作主语时，常用it作形式主语，常见的句型有：It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc. ) + that 从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc. ) + that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,etc. ) + that 从句that可以省略，但that从句位于句首时，that不能省略。
2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid 等。
在可以接复合宾语的动词之后,如think, make, consider等，可以用it作形式宾语。
(2)That从句一般不能充当介词宾语，偶尔可作except, in的宾语。
3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时，应在某些抽象名词之后,如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等，对前面的名词起补充说明的作用，that 在从句中不担当任何成分，不能省略。
二、whether/if 从句1＞在表语从句和同位语从句中，只能用whether不能用if；当主语从句放于句首时，只能用whether不用if；当it作形式主语，主语从句放在句末时用whether或if均可；discuss后引导宾语从句时，必须用whether。

3.连接词1). 从属连词：that, whether/if that：无词义，在宾从中可省（在从句中不做成分）区别：whether/if：有词义：是否例句I think (that) you are right.I don’t know whether (≠ if ) or not I should take his advice .They asked whether (= if ) we need any help.What he wants to tell us is not clear.Who will win the match is still unknown.以及：whoever, whomever, whichever, whateverwhere：哪里3). 连接副词：why：为什么（有词义，在从句how：怎么样中作状语，具体选when：什么时候择按意思）例句It is known to us how he became a writer.Where the English evening will be held has not yet been announced.以及：wherever, however, whenever注意事项：1. what，that区分：what在从句中可做主语，宾语，表语，有两个意思：东西，什么；而that在从句中不做任何成分，也没有任何意思。

但是what和who引导主语从句时，有时主句的谓语动词的数应与主句中表语的名词保持一致。
例句：1. What they bought was water.2. What they bought were books.“It”作形式主语的句型：1) It is/was +名词( no wonder, an honor, a good thing, a pity, no surprise…)＋主从例句：It is a pity that we can’t go.2) It is/was ＋形容词(obvious, natural, surprising, wonderful, possible, likely,certain…)＋主语从句例句：It is clear that Tom has returned.3) It is/was＋过去分词(said / reported / believed / known / thought / expected /decided / announced / arranged…)＋主语从句例句：It is said that President Jiang will visit our school next week.4) It＋动词(happens /occurs / seems…) ＋主语从句例句：It occurred to him that he failed in the examination.5) It doesn’t matter how/whether…例句：It doesn’t matter whether he is wrong or not.2.宾语从句(Object Clause)：作句子的宾语；位于动词或介词之后。
