宾语从句(三要素--语连时)
口诀
宾语从句三姊妹,
that,if/whether,wh-how;陈述句语序永不变;
主现从不限,主过从必过;客观真理永现。
1. 定义宾语
I know something.宾语从句·
I know that he is a hero.
总结:宾语:动词后面的名词或代词 动作的承受者
宾语从句:放在动词后面做宾语的句子(主句+连接词+从句)
二.宾语从句的种类
动词宾语从句
Do you know where he lives ?
介词宾语从句
Everything depends on whether we have enough money.
形容词宾语从句
I am sorry I am late.
I am glad that you can join us.
三.宾语从句的三要素(连接词、语序、时态)
I think that it is a touching story.
He wondered if he could shoot down the nine suns in the sky.
Chang’e didn’t know how she could keep the medicine.
1. 连接词
当宾从:that,无意,可省,用于陈述一件事情
接that宾从的动词:think, say, know, hope, wish, hear, promise, expect, believe...
eg. I hope/ that) everyone will live a happy life.
I think that you are right.
当宾从:if/whether(or not),是否,不可省
当宾从:特殊疑问词(7W+H),充当成分,不可省
if/ whether引导的宾语从句
只能用 whether不能用if情况①介宾,只能用 whether
eg. His father is worried about whether he will lose his job.
②与 or not连用时(whether or not/ whether... or not)
eg. No one knows whether they are true or not.
I want to know whether or not it' s good news.
③ whether to do sth与whether....or....
She can' t decide whether to say.
2. 语序---陈述语序(引导词+主谓+其他)
①在含有宾语从句的复合句中,宾语从句要使用陈述语序,即“引导词+主语+谓语+其他”。如:
I want to know when the train left. 我想知道火车是什么时候离开的。
注意:a. 有些特殊疑问句本身是陈述句语序。如:
What's wrong with....?
Which is the way to....?
What happened to you....?
What's the matter/trouble....?
Who studies the hardest in your class?
b. do you think后接宾语从句时,特殊疑问词即引导词要前置,do you think作为插入语。如:Who do you think he is talking with? 你认为他正在和谁交谈?
②由do, does, did构成的疑问句,在转换成宾语从句时,要去掉do, does, did,且从句中的谓语动词要根据主句时态作出相应的变化。如:
“Does he sing well?” The music teacher asked him.
→The music teacher asked him if(whether)he sang well. 这个音乐老师想知道他唱得是否很好。
③如果是will, be, have, can组成的疑问句,在变为宾语从句时,要把这些词还原到句中原来的谓语位置上,并根据主句的时态作相应的变化。如:
“Will you be free tomorrow?”She asked me.
→She asked me if (whether) I would be free tomorrow.她问我明天是否是空闲的。
3.时态(主现从不限,主过从过,真理永现)
(1)主句是一般现在时,宾语从句时态任意(需要性原则)
(2)主句是一般过去时,宾语从句用过去的某种时态(呼应性原则)
过去某种时态①一般过去时②过去进行时③过去完成时④过去将来时
