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。
