高一英语语法知识点总结（一）
1. 定义：用作表语的从句叫做表语从句。
2. 构成：关联词+简单句
3. 引导表语从句的关联词的种类：
(1) 从属连词that。
例如：The trouble is that I have lost his address. 麻烦是我把他的地址丢了。
(2) 从属连词whether, as, as if。
例如：He looked just as he had looked ten years before. 他看起来还与十年前一样。
The question is whether they will be able to help us. 问题是他们是否能帮我们。
注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，
例如：All this was over twenty years ago, but it's as if it was only yesterday. 这都是20多年前的事了，但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be, seem, look等。
例如： It looked as if it was going to rain. 看起来天要下雨了。
(3)连接代词：
Who whom whose what
Which whoever whatever whichever
连接副词：
Where when how why
例如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。
The question is how he did it. 问题是他是如何做此事的。
That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。
注：
1. 连词because可引导表语从句。
例如： I think it is because you are doing too much. 我想这是因为你做得太多。
2. 在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。
例如： My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。

如何变时态：
直接引语在改为间接引语时、时态需要做相应的调整。
现在时它需改为过去时态；过去时态改为完成时；过去完成时则保留原来的时态。如：
1)She said. "I have lost a pen."→She said she had lost a pen
2)She said. "We hope so."→She said they hoped so.
3) She said. "He will go to see his friend。"→She said he would go to see his friend。
但要注意在以下几种情况下。在直接引语变为间接引语时，时态一般不变化。
①直接引语是客观真理。
"The earth moves around the sun and the moon moves around the earth, the teacher told me. → The teacher told me the earth moves around the sun and the moon moves around the earth。
②直接引语是过去进行时，时态不变。如：
Jack said. "John, where were you going when I met you in the street?"→Jack asked John where he was going when he met him in the street。
③直接引语中有具体的过去某年、某月、某日作状语，变为间接引语时，时态不变。如：
Xiao Wang said. "I was born on April 2l, 1980。" →Xiao Wang said he was born on April 20, 1980。
④直接引语如果是一般现在时。表示一种反复出现或习惯性的动作，变间接引语，时态不变。如：
He said, "I get up at six every morning。" →He said he gets up at six every morning。
⑤如果直接引语中的情态动词没有过去时的形式（例：ought to， had better, used to)和已经是过去时的形式时，（例：could, should, would, might）不再变。如：
Peter said. "You had better come have today。" →Peter said I had better go there that day。
