2024新高考英语专题复习4：主语从句和短文缩写导学案

2024新高考英语专题复习：主语从句和短文缩写导学案 主语从句 ( 教师必读 ) 一、作主语的句子叫做主语从句。 如： (1)That he will win is certain. 他肯定会赢。 (2)Whether he will come isn’tclear. 他是否会来还不清楚。 二、 在主语从句中须注意： 1. 主语从句一般用 it 作形式主语，放在句首， 而将主语从句放到句末。如： (1)It is possible that he has stolen the car. 很可能他偷了小车。 (2)Isn’t it strange that he should not have passed the test? 他测试没有通过， 难道不奇怪吗？ 2. if 引导主语从句时，只能用 it 作形式主语，放在句首， 而将 if 引导的主语从句放到句末。如： It is uncertain if he will leave for Beijing tomorrow. 明天他是否去北京还不敢肯定。 3. that 引导主语从句放在句首时，that 不可省，但在句末口语中可省。如： That he was ill yesterday is known now. 大家都已知道他昨天生了病。 4. 连接代词引导主语从句只能放在句首。如； (1)Who has broken the glass is unknown. 谁打破了玻璃现在还不知道。 (2)What he wants is all here. 他所要的东西都在这里。 5. 主语从句中主句的谓语动词一般用第三人称单数形式， 但 what 引导主语从句的主句谓语动词形式须根据句子的意思来判断。如： (1)How he worked it out is still a secret. 他是如何把它做出来的还是一个秘密 (2)What they makes in this factory are TV sets. 他们在工厂里所做的东西就是电视机。 三、 备考主语从句应注意以下三点： 一是从句作主语，主句谓语动词用第三人称单数； 二是主语从句通常用 it 作形式主语，尤其是在 It is +名词 / 形容词 / 过去分词+that…中，或在 It seems / happens that… 中，或疑问句中； 三要注意由 what, whatever, whoever 引导的主语从句一般不用形式主语。 二、真题解析 1.
