宾语从句是考研英语中常考的语法点。
一、定义
在句子中做宾语的从句叫做宾语从句。
I know what he say.
句子中的what he say 充当know的宾语，叫做宾语从句。
二、宾语从句的分类
动词的宾语从句和介词的宾语从句
三、引导词
从属连词、连接代词、连接副词
1. 从属连词
陈述句常为that,在句子中不充当任何成分，经常被省略。
My son tells me that he likes that pretty girl.
一般疑问句常为if/whether,“是否”，if不能在whether...or not 句型中替换
I don’t know if/whether she will come.
2. 连接代词
从句为特殊疑问句时，选择连接代词或者连接副词。
主要有who, whom,whose, what,which, whoever,whatever,whichever,在宾语从句中做主语，宾语，表语，定语，不能省略。
I want to know what she plans to do.
She tells me whose the book is.
3. 连接副词
When,where,why,how,在宾语从句中做状语，不可省略。
He tells me when we can meet again.
Do you know how can they find me?
四、宾语从句的语序
须是陈述句，就是主语+谓语的顺序
He asks when we will meet again.（对）
He asks when will we meet again.（错）
五、宾语从句的否定转移
条件：1 主语须是第一人称
2 谓语动词是think, believe,suppose,imagine,guess,expect等
意义：主句否定形式，从句否定意义。
I don’t think you like music.
我认为你不喜欢音乐。
六、宾语从句的时态
宾语从句的时态由主句决定
1、主句是一般现在时，从句可以是任何时态
I remember she gave me an apple yesterday.
She tells me she will come back in a few days.
2、主句是一般过去时，从句是过去的相关时态。
主句谓语动词是过去时态，从句可以是过去的某种时态，例如，一般过去时，过去进行时，过去将来时，过去完成时。
My son told me he would take part in the activity.
He said he came back yesterday.
My son said he was reading a book at six yesterday.
My son said he had read the book several times.
注意：主句是过去时态，宾语从句叙述的真理或者事实，宾语从句要用一般时态。
They said that the earth is round.
七、宾语从句的虚拟语气
1、建议 suggest, advise,propose
2、要求 demand,desire,request
3、决定 decide
4、命令 order,command,require
5、坚决主张 insist
这些动词后使用宾语从句，要用（should）+V （虚拟语气）
My son insists that I should go home.
My mom suggests that I should stop eating too much.
The leader orders that we should finish our task at once.
八、宾语从句的简化
在混合句中，英语习惯把真正的宾语放在后面，用it做形式主语。常见使用形式宾语动词有make,find,see,hear,feel,think等等。
I find it difficult to stop eating too much.
I think it necessary that we should take plenty of water every day.
