高中英語同位語從句知識點整理
1. 定義:用作同位語的從句叫做同位語從句。
2. 用法:同位語從句的先行詞多為fact, news, idea, thought, question, reply, report, remark等,關聯(lián)詞多用從屬連詞that。
例如:
they were all very much worried over the fact that you were sick. 對你生病這件事,他們都很焦慮。
where did you get the idea that i could not come? 你在哪兒聽說我不能來?
注:同位語從句偶爾由從屬連詞whether引導。
例如:i have no idea whether he'll come or not. 我不知道他是否來。
連接代詞who, which, what和連接副詞where, when, why, how亦可引導同位語從句。
例如:
the question who should do the work requires consideration. 誰該干這項工作,這個問題需要考慮。
it is a question how he did it. 那是一個他如何做了此事的問題。
注:
1.一些表示“建議、命令、要求”的名詞后所跟的同位語從句中,謂語動詞用虛擬語氣should+動詞原形表示。should可省。
例如:
this is our only request that this (should) be settled as soon as possible. 這就是我們唯一的請求:盡快解決這個問題。
2.引導詞that在同位語從句中不作句子成分;而在定語從句中必作句子成分,是從句所修飾的詞的替代詞。
例如:
the fact that the chinese people invented the compass is known to all.中國人發(fā)明指南針這個事實是眾所周知的。(同位語從句)
the fact that we talked about is very important.我們談論的這個事實很重要。(定語從句)
