您好！
宾语从句，是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。
Everything depends on whether you agree with us.

He knows where they live.
He didn't say when he would return.
I don't know why she is crying.

本回答被提问者和网友采纳官方释义：在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。
因此判断宾语从句有两个依据：
从句前有动词或者介词或者是形容词
从句在主句中充当宾语（即主句不完整，缺少宾语）
【例】
Ma ma says that I am just a child. (that 引导的从句做say的宾语)
I am glad that you will come tonight. (that引导的从句做be glad的宾语)
宾语从句连接词如下：
感谢采纳～
在句中起宾语作用的从句叫作宾语从句
1. 从属连词that, whether, if引导宾语从句，that无意义，whether/if有“是否”的意思
He said that he couldn't come to our party tonight.
Nobody knows whether/if he likes to learn a foreign language.
2. 连接代词who, whom, which, what, whose, whatever等引导宾语从句
I want to know what the manager said at the meeting.
Do you know who is in charge of the chemical works.
3. 连接副词when, where, why, how, whenever等引导宾语从句
The policewoman asked me how the car accident happened.
I knew where he was hiding.
that连词：引导宾语从句：陈述事实，that无意义，只是个引导词。He said that he would come to our school.他说他要来我们学校。
whether连词：引导宾语从句，有“是否”的意思，有一般疑问意思。He asked whether I would come.他问我是否会来。
what连接代词，什么，所……的， 在宾语从句中充当主、宾、表语。He knew what he was going to do. 他知道他要做什么。(what宾语）
who连接代词，谁，宾语从句中充当主、宾、表语。He asked me who would come to help me.他问我谁会来帮助我。（who主语）
which连接代词，哪（些），哪个，在宾语从句中充当主、宾、表、定。I wonder which book you like better.我不知道你更喜欢哪本书。（which定语）
where连接副词，哪里，在宾语从句中充当状语，表示地点。Please let me know where he will go.（where地点状语)
