一、语序无论主句是陈述句还是疑问句，宾语从句都必须使用陈述语序，即“主句+连词+宾语从句(主语+谓语+……)”句式。1. 连接词+谓语。连接词在从句中作主语。常见的连接词有：wh，what，which等。如：Culd yu tell me wh knws the answer, please?
2. 连接词+名词+谓语。连接词在从句中作主语的定语。常见的连接词有：whse，what，which，hw many，hw much等。The teacher asked us hw many peple there were in the rm.3. 连接词+主语+谓语。连接词在从句中作宾语、状语或表语。常见的连接词有：wh(m)，what，which, hw many, hw much, when, why, hw, where, if /whether(在句中不充当任何成分)。He hasn't decided if he'll gn a trip t Wuxi.Culd yu tell me what I shuld d with the mney ?
4. 连接词+名词+主语+谓语。连接词在从句中作宾语或表语的定语。常见的连接词有：what，which，hw many，hw much，hw等。D yu knw which class he is in ?She asked me if I knew whse pen it was.
二、引导词1. 当由陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。He said that he culd finish his wrk befre supper.2. 当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。I dn't knw if /whether he still lives here after s many years.
但在下列情况下只能用whether：1）与r或r nt连用时Let me knw whether he will cme r ntI wnder whether we stay r whether we g2）在介词之后用whether。We're thinking abut whether we can finish the wrk n time.3）在不定式前用whether。I dn't knw whether t g.
4） whether置于句首时，不能换用if。Whether this is true r nt，I can't say.这是否真的我说不上来。5）引导主语从句和表语从句时宜用whether。如：Whether she will cme r nt is still a questin.The questin is whether we can catch the bus.3. 如果宾语从句原来是特殊疑问句，只需用原来的特殊疑问词引导。Culd yu tell me why yu were late fr the meeting this mrning?
三、时态含宾语从句的复合句，主、从句谓语动词的时态呼应应包括以下三点内容：1. 如果主句的谓语动词是一般现在时，从句的谓语动词可根据需要，选用相应的任何时态。I dn't knw when he will cmeback.He tells me that his sister came back yesterday.
2. 如果主句的谓语动词是过去时，宾语从句的谓语动词只可根据需要，选用过去时态即一般过去时、过去进行时、过去将来时或过去完成时的某一种形式。The children didn't knw wh he was.He asked his father hw it happened.3. 如果宾语从句所表示的是客观事实、普遍真理、自然现象或习惯性动作等，不管主句用什么时态，从句时态都用一般现在时。The teacher said that the earth ges rund the sun.
—I dn't knw if he will cme.我不知道他是否会来。—He will cme if it desn't rain.如果不下雨，他会来的。
—D yu knw when he will cmeback tmrrw ?你知道他明天什么时候回来吗?—Srry, I dn't knw. When he cmes back, I'll tell yu. 对不起，不知道。当他回来了，我将告诉你。
四、宾语从句的复合句转化为简单句1. 当主句谓语动词是hpe，decide，wish，chse，agree，prmise(和主观决定有关)等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。Li Ming hpes he will be back very sn. →Li Ming hpes t be back very sn.We decided that we wuld help him. →We decided t help him.
2. 当主句谓语动词是knw，learn，remember，frget，tell等动词，且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。She desn’t knw what she shuld d next.→She desn’t knw what t d next.Culd yu tell me hw I can get t the statin? →Culd yu tell me hw t get t the statin?
五、宾语从句的否定转移在主从复合句中，当主句的主语为第一人称，谓语动词是think，believe，suppse等时，要将宾语从句的否定词转移到主句中，即主句的谓语动词用否定形式，而宾语从句的谓语动词用肯定形式。I dn’t think he will cme with yu.
