1、精选优质文档-倾情为你奉上 宾语从句一、掌握宾语从句的概念宾语从句即指在主从复合句中用作宾语的从句。对比下面两句：简单句： I know him. 主语 谓语 宾语主从复合句： (I know ) that he is a teacher. 主句 （主语+谓语） 宾语从句如：I hope you enjoy your holiday.希望你假期过得愉快。He began to think about what he should do.他开始考虑应当怎样做。二、注意宾语从句的时态宾语从句中谓语动词的时态，常常受到主句谓语时态的制约，此为时态呼应。 若主句为一般现在时，宾语从句的时态可根据情况使

2、用任意时态； 但若主句为一般过去时，则宾语从句必须要用过去的某种时态与主句呼应。比较：He says he is busy.他说他很忙。 He said he was busy.他说他很忙。I know you will agree.我知道你会同意的。 I knew you would agree.我知道你会同意的当宾语的内容表示的是客观真理时，不管主句谓语的时态如何，从句都用一般现在时。如：The teacher said that the earth turns around the sun.老师说，地球绕着太阳转。三、明确宾语从句的语序宾语从句属名词性从句，不管用什么样的引导词引导，宾语

3、从句的语序总是用陈述语序（主语+谓语）。如：She asked when she could leave.她问她何时可以离开。Please tell me what you need.请告诉我你需要什么。四、分清宾语从句的引导词1.当宾语从句部分表示陈述句语气时，用that引导。that只起引导词作用，不充当句子成分，也没有词义，且通常可以省略。如：We think (that) he will help us.我们认为他会帮助我们。He said (that) he was good at English.他说他擅长英语。I know (that) he is very busy.我知道他很

4、忙。2.当宾语从句部分为一般疑问句时，用if或whether引导。if和whether引导宾语从句，不充当句子成分，但有词义，表示“是否”。如：I dont know if /whether he will come.我不知道他是否会来。She asked if /whether that was enough.她问那是否够了。I wonder whether /if it is true.我不知道是不是真的。一般情况下，if 和whether可以互换，但以下4种情况只能用whether：在不定式前：Whether to go there or not hasnt been decided.在

5、介词后：It depends on（依靠） whether it is going to rain.与or not连用：They are talking about whether to go there or not.宾语从句位于句首时：Whether well attend the meeting,no one knows.3.如果宾语从句原来为特殊疑问句时，用特殊疑问词引导。常见的引导宾语从句的特殊疑问词有what, who, whom, which, whose,when, how, where, why等。此时要特别注意宾语从句用陈述句词序，而不用疑问句词序。如：She asked

6、who would like to go. Tell me whose wallet this is. I dont know _(他有什么问题）。.He knows _他知道他们住哪里。Tell us how you are getting on now.告诉我们你现在过得怎样？I cant tell you _.我不能告诉你她为什么在哭。He didnt say _.他没有说什么时候回来。what引导宾语从句时，有时表示“什么”，有时表示“所的”: I asked what he needed.我问他需要什么。I gave him what he needed.我给了他所需要的东西。 Pl

7、ease remember_(我昨天所说的话）.【注意】1由特殊疑问词引导的宾语从句可以和“疑问词+不定式”结构转化同义句。eg. I dont know how I should do with the presents. = I dont know how to do with the presents.Eg:1)Please tell me what I should do next.(改同义句)Please tell me what _ _ next.2) I havent decided where I will go.(改同义句) I havent decided _ _五、宾语从

8、句与否定前移当主句的主语为第一人称，动词为think, believe, suppose, expect, imagine，后接一个表示否定意义的宾语从句时，其否定通常转移到主句。如： I dont think that it is worth doing.我认为这不值得做。I dont believe that he will help us.我相信他不会来。：）（合并为复合句）（合并为复合句）六 宾语从句和状语从句的区分eg. 1） I will go out tomorrow if it is fine.it is fine，I will go out tomorrow2） I dont

9、 know if the train has arrived.句1）中if引导的是条件状语从句。这个从句表示“条件”，修饰主句。句子的意思是如果明天天气好，我就出去。句2）中if引导的是宾语从句，充当谓语动词dont know的宾语。句子的意思是我不知道火车是否到达。判断方法：1可以从整个句式看。状语从句一般可以放在主句的前面或后面（个别除外）， 宾语从句只能放在主句谓语动词之后。2从引导词看。if充当宾语从句的连接词时，相当于whether， 词义为“是否”，充当条件状语从句的连接词时，词义为“如果”。 when充当宾语从句的连接词时，意为“什么时候”，充当状语从句的连接词时，意为“当的时候

10、”。Eg:（从句）（从句）3从时态看。if和when作连接词时，引导宾语从句要注意：从句的谓语动词的时态应根据主句的时态作相应的变化。if和when充当从属连词时，引导条件和时间状语从句，若主句的谓语动词用一般将来时，则从句的时态应用一般现在时表示将来（主将从现）。Eg:（_从句）。（_从句）七、宾语从句与形式宾语it当宾语从句后跟有宾语补足语时，通常在宾语从句处使用形式宾语it，而将真正的宾语从句移至句末。如：I think it best that you should stay here.我认为你最好住这儿。He hasnt made it known when he is going

11、to get married.他还没宣布他何时结婚注意：标点由主句决定，如主句是陈述句、祈使句，则用句号；是疑问句则用问号。eg. I heard she had been to the Great Wall. Can you tell me which bus I should take?宾语从句练习题一 选择 。1.
