知识的学习需要的不仅是大量的做题,更重要的是知识点的累积。威廉希尔app 初中频道为大家准备了宾语从句知识点,欢迎阅读与选择!
用作宾语的从句叫宾语从句。宾语从句不仅可以用作及物动词的宾语,还可以用作介词或某些形容词的宾语。宾语从句的语序只能用作陈述句语序。
一、宾语从句的引导词
1.由连词that引导,在口语或非正式文体中可以省略。例如:
He said he would go to Tokyo on business the next day.
注意:
当引导词that引导几个表示并列关系的宾语从句时,最后一个that不能省掉。
2.由if,whether引导,宾语从句属于一般疑问句时,语序一定是陈述句语序。例如:
I wondered if/whether he would come to meet me on time .
注意:
1)if 与whether一般是可以互换的,但在引导由选择疑问句变来的宾语从句时,只可以用whether。
I don't know whether the pen is his or yours.
2)如果宾语从句有or not,也只能用whether引导
I wonder whether he will come to my birthday party or not.
3)由连接代词或副词(who,whose,what,which,when,where,why,how)引导的宾语从句
He wondered what had happened to her.
Can you tell me where the nearest post office is?
二、宾语从句语序
宾语从句要用陈述语序,特别是由疑问句变来的宾语从句要将助动词、系动词移至主语之后或与它的谓语动词合并
“Where do you come from?”he asked.=He asked where you came from.
I don't know what the weather is like there.
三、时态呼应
1.若主句为一般现在时态或一般将来时态,从句的时态不限,可视句子而定,使用所需的任何时态。
We all know chickens can't swim.
She says she will come back.
2.若主句是祈使句,从句也可用所需的任何时态
Show me which picture is yours.
3.主句是一般过去时态,从句必须用过去完成时态
I knew she had swept the floor already.
4.若从句叙述的是客观真理、自然现象或永恒不变的规律时,则不受主句时态限制,仍用一般现在时态。
Our physics teacher told us that light travels faster than sound.
She said one and two is three.
四、否定转移
如果在动词think,believe,suppose,guess之后的宾语从句是由that引导的否定从句,且主句是第一人称,否定要转移到主句上。
I don't believe he is a boy of five years old.
I don't think you are right.
