3.由连接代词 Who,whom,whose,which,what和连 接副词 where,how,why,when引导的宾语从句。这 些连词既有词义又充当句子成份。 e.g. 1)Do you know whose book it is ?（谁的，作定 语）
2)Could you tell me why the train is late? （为 什么，作状语）
3)He asked who could answer the question.（谁， 作主语）
二、语序
宾语从句的语序用陈述语序：
主句+引导词+主语+谓语+其他
1.陈述句——基本不变 He said, “Lucy is younger than Tom”. He said (that) Lucy was younger than Tom. He says, “ Tom is a good student.” He says (that) Tom is a good student.
2. He says, “Tom is a good student ”. He says (that) Tom is a good student.
2. 当宾语从句是一般疑问句时，
由连词whether 或if引导（口语中常用if），译为“是否”， 不能省略。
1. She asked, “ Do they often come here early? ” She asked if/whether they often came here early.
3. Where did Anna go yesterday? I know where Anna went the day before.

语序 时态
一、引导词（连词） 1. 当宾语从句是陈述句时（包括肯定句/否定句）,
连词由that引导, 因为that在从句中不作任何成分，也没 有任何具体意思，因此在口语或非正式文体中常省略。
1. He said, “life is better than before”. He said (that) life was better than before.
2. I don’t care of ______ he is handsome. 介词后只能用whether
3. He wondered ______ to stay here the next week. 与to do 不定式连用只能用whether
4. ____ he will come is not decided.
2). I don’t know when hew_i_ll__c_o_m__e_ (come) . I can’t wait here any more . When he ___c_o_m__es
(come) , would you please ask him to call me ?
