名词性从句可分为主语从句、表语从句 、宾语从句和同位语从句。

　　（1）宾语从句

　　宾语从句在复合句中起宾语作用，可以作动词的宾语，也可以作介词的宾语。引导宾语从句词有:

　　连词that，if，whether；

　　连接代词who，whose，what，which；

　　连接副词when，where，how， why等。

　　The Object Clause

　　e.g.

　　1)I think (that) women can reach very high achievements in many fields of science.

　　2) I wonder whether/if she remembered how many babies she had delivered.

　　3) Do you know who/whom Jack was speaking to?

　　4) He asked whose car it was.

　　5) Pay attention to what the doctor said.

　　6) Please tell me when the earthquake took place.

　　7) Will you tell me how I can keep fit and healthy?

　　做动词的宾语

　　(1)大部分宾语从句直接跟在动词后：

　　 e.g.

　　 He doesn't know where the post office is.

　　 (2)有些宾语从句前要有间接宾语：

　　 e.g. He told me what I should read．

　　　(3)如果宾语从句后面有宾语补足语，要使用形式宾语 it 而将从句放到补足语后面；

　　 e.g. I thought it strange that he failed to call me．

　　 我觉得奇怪：他没给我打电话。

　　　(4)在think, believe, suppose, expect等动词之后的宾语从句中，如果从句谓语是否定含义，则不用否定形式,而将主句谓语动词think等变为否定形式;

e.g. I don't think you are right．
