宾语从句知识点详解思维导图

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.
