名词性从句
概念:在复合句中起名词作用的从句叫名词性从句 (Noun Clauses）。名词性从句的功能相当于 名词, 它在复合句中能担任主语、宾语、表语、 同位语等，因此根据它在句中不同的语 法功能，名词性从句又可分为主语从句、宾语从 句、表语从句和同位语从句。
He is thinking about how to solve the problem.
3).用作某些形容词的宾语：

all. ×
3. When he did the experiment has not
been decided yet. √
2. What 引导主语从句时,主句谓语 动词的单复数由表语的单复数决定.
• What he wants _a_re____these books.
• What he wants __is____some water.
三.主语从句的两种结构:主语从句可 以放句首；也可以放句末，用it 做形 式主语. For example:
1.That the earth is round is true. = It is true that the earth is round.
2.Whether he will come hasn’t been decided.
= It hasn’t been decided whether he will come.
以it作形式主语，把主语从句后置的常用句 型有：
1. It +be+形容词+that从句
（1）It is certain that she will do well in her exam.
（2） It is possible that he told her everything.
(2) It is thought that Joe drives badly.
4、It + 不及物(happen, appear等)
动词 + that从句。 (1) It happened that I was out that day.
注意 主语从句中的“主谓一致”：
1.一个主语从句作主语相当于第三人称 单数作主语，谓语动词用单数；
