宾 语 从 句
The Object Clause
一、宾语从句的概念
在复合句中,由一个句子充当宾语,这个句子叫宾语从句。
We know that Mr Green teaches English.
She asked if these answers were right.
句子结构:
主句 + 引导词+ 宾语从句
二、宾语从句三要素
引导词
语 序
时 态
一、引导词
1. 当宾语从句是陈述句时(包括肯定句和否定
句), 引导词由that引导, 因为that在从句中不作
任何成分,也没有任何具体意思,因此在口语
或非正式文体中常省略。
Our teacher told us (that) light travels
faster than sound in yesterday’s class .
2. 当宾语从句是一般疑问句时,由连词whether或if引导,if/whether翻译为:“是否”,具有一定的意义,不能省略。
Do you know if/whether the students
had a picnic last Sunday
If 与whether 的区别
I don’t know _____ he will come or not.
与or not 连用只能用whether
It is the same to me whether they come or go.
不管......还是 无论......还是
3. 当宾语从句是特殊疑问句时,由原特殊疑问词引导,因为特殊疑问词在从句中担任一定的句子成分,具有一定的意义,所以不可以省略。
.
Please tell me which book I should read first .
