1、 宾语从句专题宾语从在复合句中用作宾语的从句叫宾语从句。1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。2连接词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。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”。如：I dont know if whether he still lives here after so many years我不知道这么多年后他是否还住在这儿。但在下列情况下只能用whether：在具有选择意义，又有or或or not时，尤其是直接与or not连
2、用时，往往用whether（ifor not也可以使用）。在介词之后用whether。在不定式前用whether. whether置于句首时，不能换用if。引导主语从句和表语从句时宜用whether。若用if会引起歧义时，则用whether.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。3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。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。3）
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。4注意：if和when既可以引导宾语从句，也可以引导状语从句，应注意它们在两种从句中的意思和用法的不同。if和when引导宾语从句时，分别意为“是否”和“何时”，其时态应和主句时态相呼应；它们引导状语从句时，意思分别为“如果，假如”和“当时候”，当主句时态是一般将来时时，其时态用一般现在时。它们常常放在含有状语从句和宾语从句的题干中进行综合考查。如：Do you know when he will come back tomorrow ？你知道他明天什么时候回来吗？Sorry，I do
4、nt knowWhen he comes back，Ill tell you对不起，不知道。当他回来了，我将告诉你。I dont know if he will come我不知道他是否会来。He will come if it doesnt rain如果不下雨，他会来的。一. 基础练习1.
