名词性从句详解(主语从句、并与从句、表语从句与同位语从句)
主语从句如果一个句子在复合句中充当主语,那么这个句子就是主语从句。
主语从句主要有以下三类：1．由what等代词引导的主语从句：这类主语从句可由三类代词引起：1)whatWhat you need are more friends．What I did made my teacher angry．2)whateverWhatever I have done is for you.Whatever has been done here is helpful for your future．3)whoeverWhoever comes here will be welcome．Whoever take part in the activity will get reward．what 引导的主语从句，主句谓语动词通常用单数形式，但有两种特殊情况：a)what在从句中作主语时，主句谓语动词的单复数与从句的谓语动词保持一致。
What makes him happy also makes me happy.What are put into the box are important to me.b) 当主句中的表语是复数时，主句谓语动词用复数，否则用单数。
What he gave are five books.2．由that引导的主语从句：这类主语从句大多数用it作形式主语，而真正的主语放到句子后部，以保持句子的平稳，也有少数直接用这种从句作主语，不用it。
（主语从句位于句首时，that不可省略；当用it作形式主语，真正的主语放置在句尾，且谓语动词为seem、appear、be a pity、be a wonder、be likely时，that可省略。
）1）It’s a pity(that)you can’t come to my party．2）That she works hard makes her leaders satisfied．3）That Jack becomes a doctor is his mother’s wish. 3．由连接代（副)词及whether引导的主语从句：这类主语从句可以直接放在句首，也可以放到句尾，前面用先行词it作形式上的主语。
高中英语知识点归纳表语从句与同位语从句的区别
高中英语知识点归纳表语从句与同位语从句的区别高中英语知识点归纳——表语从句与同位语从句的区别表语从句和同位语从句是英语语法中相似但又有细微差别的两个概念。
在句子中，它们都可以作为主语、宾语或表语，但它们在句法结构和使用方法上有一些显著的区别。
本文将重点介绍表语从句和同位语从句的区别，帮助读者更好地理解并正确运用这两个知识点。
一、表语从句表语从句是一个从句，用来作为句子的表语。
它通常用来描述或说明主语的状态、性质、身份、职业等。
表语从句一般由连接词that引导，连接词that在口语中常被省略。
1. 结构及例句：表语从句的结构为：主语 + be动词/系动词 + that从句。
例如：- My dream is that I can travel around the world one day.（从句作主语）- The fact is that he didn't pass the exam.（从句作表语）2. 特点：- 表语从句中的谓语动词通常是be动词或系动词。
- 表语从句中的连接词一般为that，有时也可以用whether或其他连接词。
- 当主句的主语和表语从句的主语一致时，表语从句的主语可以省略，而只保留连接词和谓语。
二、同位语从句同位语从句是一个从句，用来解释或说明前面的名词或代词的含义、意义等。
同位语从句常常用来作为名词的同位语，起到进一步解释说明的作用。
1. 结构及例句：同位语从句的结构为：名词/代词 + 连接词 + 从句。
例如：- The fact that he didn't pass the exam disappointed his parents.（从句作同位语）- I have no idea who will be the winner.（从句作同位语）2. 特点：- 同位语从句中的连接词可以是that、whether、if等。
