构成方式
（一）主语+及物动词+宾语从句
注意：不是所有的及物动词都可以跟宾语从句，可以分为两种：
1、主语+特定的及物动词+that引导的宾语从句
I know (that) you are right.
I don’t think that you understand it.（否定前置）
I realize that I need to improve my skills.
2、主语+特定的及物动词+其他连接词引导的宾语从句
I wonder if my students passed the exam.
I don’t know what you like.
I forget what I said last night.
复合句本身也可以变成否定句、一般疑问句和特殊疑问句。
I know that Lily is a teacher.
I don’t know that Lily is a teacher.
Do you know that Lily is a teacher?
When did you know that Lily is a teacher?
（二）主语+双宾动词+间接宾语+宾语从句（直接宾语）
注意：“双宾动词不多；间接宾语都是表示人的词语；宾语从句由that或其他的连接词引导的宾语从句都可”
I ask him where my money is?
My parents always ask me when I will get married
My mother showed me how she made soup.
I often tell my students how I learned English before.
I write to my friend that I will set up a company.
I never asked Conseil if my traveling would be convenient for him.
（三）主语+特定的及物动词+宾语从句+形容词（宾补）
注意：“能跟形容词做宾补的特定的及物动词常见的有, Make Prove Think Find Consider等”
避免头重脚轻的规则，复合句句型如下：
主语+特定的及物动词+ it +形容词（宾补）+宾语从句(that从句为主)
I think it possible that Lily will be a good teacher.
I consider is necessary that we should spend more time reading English novels.
She made it clear that she would carry out her plan.
（四）主语+be+某些形容词+宾语从句
注意：“只有特殊的形容词作表语，后面才可以跟宾语从句，常见的有，sure glad happy worried afraid proud certain surprised curious等”
I am sure that you can pass the exam.
I am worried if she can come.
She is curious how you could open the lock with a card.
I am proud that my daughter can dance beautifully.
（五）动词不定式后面的宾语从句
注意：To+特定的及物动词+宾语从句（动词不定式的宾语）= 很长的动词不定式短语。
To know that she is beautiful.
To know where my wife is yesterday
根据动词不定式短语的作用，至少有五种复合句型：
It+ be +表语+含有宾语从句的动词不定式短语（作主语）
主语+ be+含有宾语从句的动词不定式短语（作表语）
主语+特定的及物动词+含有宾语从句的动词不定式短语（作宾语）
主语+特定的及物动词+宾语+含有宾语从句的动词不定式短语（作宾补）
主谓宾或主系表+含有宾语从句的动词不定式短语（作状语）
It is hard for him to admit that he stole a car last night
A reporter’s duty is to report what really happens every day.
I want to know why you didn’t come yesterday.
You want us to know that you are rich.
I am here to see what has happened.
（六）动名词后面的宾语从句
注意：特定的及物动词ing+宾语从句= 很长的动名词短语。
复合句句型，参考动词不定式
（七）介词后面的宾语从句
1、介词+宾语从句，能跟句子的介词很少，常见的介词有by和from
They were shocked by what they saw.
We know the truth from what she said
2、特定的含有介词的及物动词短语+宾语从句，常见的动词短语有，depend on, think of, talk about, find out, complain about, insist on等
注意：如果宾语从句是that引导的从句，那么动词短语里面的介词一般要省略。其他连接词引导的从句，一般不能省略。
She complains that her husband has low salary.（省略介词about）
We complain about why we can’t get high salary.
3、含有介词的固定结构或句型
注意：如果是that引导的宾语从句，也要省略介词
I am proud of what I do every day.
I am proud that I can fly. （省略介词of）=主语+be+某些形容词+that引导的宾语从句。
I am sure of where he was last night
I am sure that he likes you.
（八）宾语从句的时态
注意：“含有，主语从句和表语从句的复合句，不需要考虑从句和复合句之间的时态问题，根据表达的意思决定使用什么时态，且符合逻辑。宾语从句的时态都是取决于复合句的时态。”
需要考虑改变宾语从句的时态，有以下4种复合句句型：
主语+特定的及物动词+宾语从句
主语+双宾动词+间接宾语+宾语从句
主语+特定的及物动词+it+形容词+宾语从句
主语+be+某些形容词+宾语从句
1、复合句用一般现在时，一般将来时，现在进行时，现在完成时，宾语从句一般可以使用任何时态。
I don’t know what you do every day
I don’t know what you are talking about
She has known that you are a monk.
2、复合句用一般过去时，过去将来时，过去完成时，过去进行时，宾语从句一般要用过去时态
She told me that she was doing her homework at that time.
I thought that you were right last night.
I didn’t know why you did not come yesterday.
3、宾语从句表示“真理”，可以用一般现在时，不受复合句的时态影响。
Our teacher told us that the earth goes around the sun.
How did you know I am poor.
动词不定式，动名词，介词后面的宾语从句一般不受复合句的时态影响。
