宾语从句一， 宾语从句用法口诀宾语从句须注意，几点事项应牢记一是关键引导词，不同句子词相异陈述句子用that；一般疑问是否（if，whether）替；特殊问句更好办，引导还用疑问词二是时态常变化，主句不同从句异主句若为现在时，从句时态应注意；主句若为过去时，从句时态向前移三是语序要记清，从句永保陈述序具体描述1：宾语从句的时态变化宾语从句的时态受主句的限制，即：主句是一般现在时态，从句根据实际情况而定主句是一般过去时态，从句用相应的过去的时态如果从句的动作发生在主句之前，则从句要用过去完成时态特殊1：Could you tell me…是用来征询对方的意见，语气委婉，并不表示过去eg: 2. Could you tell me when we will visit the Histury Museum?具体描述2：that不可省略① 当宾语从句的主语是that 时Jane says that that is a wonderful place.② 当从句前由插入语时It says, on the card, that it is made in China.③ 当宾语从句中还有主从复合句时。
I’m afraid that if you’ve lost it, you must pay for it.④ 两个或多个宾从由并列连词连接时，第一个that可以省略，但第二个that不可以省略He said (that) the film…and that he enjoy it very much.具体描述3：宾语从句的否定转移在think, believe, suppose, expect等动词引起的宾语从句中，有时谓语尽管是否定意义，却不用否定形式，而将think 等动词变为否定形式例：I don’t think you are right. (我认为你做的不对)具体描述4：宾语从句的简化1, 如果宾语从句的主语和主句的主语是同一个人时，主句的谓语动词为hope, wish, decide, agree, choose,从句简化为不定式 I hope that I can hear from you soon. =I hope to hear from you soon.2, 如果宾语从句的主语和主句的主语是同一个人时，主句的谓语动词为know, remember, forget, learn,从句可以用“疑问词+不定式”做宾语的简单句结构。
例： I don’t know what I should do next.=I don’t know what to do next. He didn’t know where he would live. =He didn’t know where to live.3，当主句的谓语动词ask, tell, show, teach时，且宾语从句的主语和主句的间接宾语一致时，从句可简化为“疑问词+不定式”Will you please show me how I can work it out?=Will you please show me how to work it out?4, 动词seem 后的宾从可用不定式来简化，但句型要有适当的变化，通常将宾从的主语作为简化的句子的主语，seem（适当形式）做谓语 It seems that football is very interesting.=Football seems to be very interesting.由从属连词whether, if 引导的宾语从句在介词后面的宾语从句中不用if引导例：Everything depends on whether we have enough money。
和不定式连用作宾语时不用if引导.例：It hasn’t been decided whether to go there or not.附加部分：中考直击（2010 河南）Some of my friends are interested in science, but none of them can tell ____.
