名词性从句
语法专题二：名词性从句1. 名词性从句的基本概念：1) 主语从句：在句中充当主语；亦可用it作形式主语，主语从句置于句末。
2) 宾语从句：在句中充当及物动词或介词的宾语；亦可用it作形式宾语，宾语从句置于句末。
3) 表语从句：在句中充当系动词的表语。
4) 同位语从句：常置于fact, idea, news, promise, doubt, suggestion, possibility, belief等表示有内容的名词后，起解释、说明作用。
2. 注意：1) 名词性从句要用陈述句语序。
2) 名词性从句中缺少主语、表语、宾语时：常用what 导，亦可用which表示选择，用who/whom/whoever指人。
缺少状语：用where（表地点）, when（表时间）, how（表方式）, why（表原因）。
3) 如不缺成份：主语从句、同位语从句用that引导，不能省略；表从、单个动词宾从可省略引导词that；介词宾从、第二个宾从，引导词that一般不省略；it作形式主语或宾语时，引导实际主从或宾从，一般that不省略；当主从、宾从本身为复合句时，引导词that不省略。
如：He told us sadly that what he had done secretly was discovered by his parents.4) 含宾从的复合句中，主句和从句的时态保持一致，但如果从句中表示是客观现象，虽然主句是过去时态，从句仍用一般现在时。
5) 主语从句做主语，谓语动词用单数；如果由and 连接两个或两个以上的主语从句做主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用单数。
6) 当主句是I/We think（或suppose, expect, believe, imagine, guess）时，其后的宾语从句如果是否定的，常常把否定词not从从句中移到主句中。
7) 只能用whether，不能用if表示“是否”的情况如下：(1) 在表语从句和同位语从句中；(2) 在主语从句中，如果用it做形式主语，whether和if都能引导主语从句，否则，只能用whether(3) 在介词之后；(4) 后面直接跟动词不定式；(5) 与or not连用；(6) 引导让步状语从句，只能用whether。

名词性从句知识点
名词性从句知识点在英语语法中，名词性从句是一个重要且复杂的部分。
它在句子中起着名词的作用，包括主语从句、宾语从句、表语从句和同位语从句。
接下来，让我们逐一深入了解。
一、主语从句主语从句即在句子中充当主语的从句。
例如，“What he said is true”（他说的是真的。
）在这个句子中，“What he said”就是主语从句。
引导主语从句的连接词主要有三类：1、从属连词：that、whetherThat he will come is certain （他会来是肯定的。
）这里的“that”在从句中不充当成分，只起引导作用。
Whether she will go there is not decided （她是否会去那里还没决定。
）“whether”表示“是否”。
2、连接代词：what、who、which、whose、whatever、whichever、whoever 等What you need is more practice （你需要的是更多的练习。
）“what”在从句中充当宾语。
3、连接副词：when、where、why、how 等When the meeting will be held has not been announced （会议何时举行还未宣布。
）需要注意的是，主语从句后置时，常用 it 作形式主语，而将真正的主语从句放在后面。
例如：It is unknown whether he will come （他是否会来还不知道。
）二、宾语从句宾语从句在句中充当宾语。
比如，“I know that he is a student”（我知道他是个学生。
）“that he is a student”就是宾语从句。
引导宾语从句的连接词与主语从句类似：1、从属连词：that（在口语或非正式文体中常省略）、whether、ifHe said （that) he was busyI wonder if/whether he will come2、连接代词：what、who、which、whose、whatever、whichever、whoever 等She asked me what I was doing3、连接副词：when、where、why、how 等Could you tell me how I can get there?宾语从句的时态要根据主句的时态来变化。
