高中英語語法:表語從句以及主語從句分析
英語的語法一直是一個非常重要的成分,是英語學習彙總必不可少的一個基石,在高中英語的學習中,如果能夠掌握一個比較全面熟練的語法知識體系,在後續的英語學習過程中會非常容易並且遊刃有餘,今天就讓我們一起來學習關於高中英語語法中的:表語從句以及主語從句吧。
一、表語從句
1.定義:用作表語的從句叫做表語從句。
2.構成:關聯詞+簡單句
3.引導表語從句的關聯詞的種類:
(1)從屬連詞that。
如:The trouble is that I have lost his address.麻煩是我把他的地址丟了。
(2)從屬連詞whether,as,as if。
如:He looked just as he had looked ten years before.他看起來還與十年前一樣。
The question is whether they will be able to help us.問題是他們是否能幫我們。
注:從屬連詞if一般不用來引導表語從句,但as if卻可引導表語從句,如:All this was over twenty years ago,but it's as if it was only yesterday.這都是20多年前的事了,但宛如昨天一樣。
能跟表語從句的謂語動詞一般為系動詞be,seem,look等。如:It looked as if it was going to rain.看起來天要下雨了。
(3)連接代詞who,whom,whose,what,which,whoever,whatever,whichever 連接副詞where,when,how,why。
如:The problem is who we can get to replace her.問題是我們能找到誰去替換她呢。
The question is how he did it.問題是他是如何做此事的。
That was what she did this morning on reaching the attic.那就是她今晨上了閣樓乾的。
解釋:1.連詞because可引導表語從句。
如:I think it is because you are doing too much.我想這是因為你做得太多。
2.在一些表示“建議、勸説、命令”的名詞後面的表語從句中,謂語動詞用虛擬語氣。
should+動詞原形表示,should可省略。如:My suggestion is that we (should)start early tomorrow.我的建議是我們明天一早就出發。
二、主語從句
1.定義:用作主語的從句叫做主語從句。
2.構成:關聯詞+簡單句
3.引導主語從句的關聯詞有三類:

如:That they were in truth sisters was clear from the facial resemblance between them.很明顯,她們確是親姐妹,她們的臉型很相似。
(2)從屬連詞whether。
如:Whether he’ll come here isn’t clear.他是否會來這裏還不清楚。
(3)連接代詞who,whom,whose,what,which,whoever,whatever,whichever 連接副詞where,when,how,why。
如:What she did is not yet known.她幹了什麼尚不清楚。
How this happened is not clear to anyone.這事怎樣發生的,誰也不清楚。
