高三英語單元必備知識點分析3
用來作主語的句子叫做主語從句。如：
(1)When he was born is unknown. 他生於何時還不知道。
(2)What he did last night is being investigated. 他昨天晚上幹了些什麼正在調查之中。
在主語從句中須注意：
1. 主語從句一般用it作形式主語，放在句首，而將主語從句放到句末。如：
(1)It is possible that he has stolen the car. 很可能他偷了小車。
(2)Isn’t it strange that he should not have passed the test?他測試沒有通過，難道不奇怪嗎?
2. if引導主語從句時，只能用it作形式主語，放在句首，而將if引導的主語從句放到句末。如：
It is uncertain if he will leave for Beijing tomorrow. 明天他是否去北京還不敢肯定。
3. that引導主語從句放在句首時，that不可省，但在句末口語中可省。如：
That he was ill yesterday is known now. 大家都已知道他昨天生了病。
4. 連接代詞引導主語從句只能放在句首。如;
(1)Who has broken the glass is unknown. 誰打破了玻璃現在還不知道。
(2)What he wants is all here. 他所要的東西都在這裏。
5. 主語從句中主句的謂語動詞一般用第三人稱單數形式，但what引導主語從句的主句謂語動詞的形式須根據句子的意思來判斷。如
(1)How he worked it out is still a secret. 他是如何把它做出來的還是一個祕密
(2)What they makes in this factory are TV sets. 他們在工廠裏所做的東西就是電視機。
