宾语从句知识点详解思维导图模板大纲
Lily likes the book.(名词作宾语)
I like it.(代词作宾语)
He enjoys fishing.(动名词作宾语)
Tom said he was a good boy. (句子作宾语)
通过上述例句,可以看出名词、代词、动名词、句子等都可以做宾语,那么由句子来充当宾语就是我们今天要讲的宾语从句。
1、由that引导的宾语从句,that无词义,通常可省略。例句:I know (that) he is Lily’s father.例句:She doesn’t know (that) she is ill.
注意事项:当主句的谓语动词是:suppose、think、expect、believe等词时,同时宾语从句表达的是否定的意思,那么需要把否定放置到主句位置表示。例句:I don’t think he will go to Beijing with me.
2、由whether、if引导的宾语从句,意思是“是否”。例句:Do you know whether/if he will come here?例句:I wonder whether/if he will come to my party.
特殊情况:只能用whether不能用if引导的宾语从句
(1)与or not连用时。例句:Do you know whether he will come here or not?
(2)与不定式to do连用时。例句:I don’t decide whether to go to the library.
(3)在介词的后面。例句:It depends on whether it will rain tomorrow.
3、由who、whom、whose、which、what、when、where、why、how等引导的宾语从句。例句:I know where he was born.
宾语从句的语序只能是陈述句语序。
例句:Do you know where he lives?(对)
例句:Do you know where does he live?(错)
例句:I don’t know what they are looking for.(对)
1、主句的谓语动词是一般现在时或一般将来时,从句可以根据句意需要使用任意时态。
例句:I know where he lived.
例句:I know where he lives.
例句:He knows where they live.
2、主句的谓语动词是一般过去时,从句只能用相应的过去时态。
例句:She told me that she was born in China in 2021.
例句:She said that she would go back to China.
例句:She was sorry that she hadn’t finished her homework.
