初三英语复习—宾语从句(The Object Clause)一、在复合句中做宾语的从句叫做宾语从句，它有三种类型。
(一)由that引导的宾语从句。
这种宾语从句中的that本身没有词义在口语或非正式文体中可以省略。
例如：1.I hope(that)he will come tomorrow.我希望他明天来。
2.He said(that)he would study English harder than before.他说他将比以前更努力地学英语。
(二)同连接代词who,whose,what,which和连接副词how,when where引导的宾语从句。
这些连词在句中作成分，有实际意义不能省略。
例如：1.I don't know who he is. 我不知道他是谁。
2.Could you tell me whose room this is? 你能告诉我这是谁的房间吗？3.He asked me which class I was in. 他问我在哪个班。
4.We didn't know when we would meet. 我们不知道我们将在哪儿见面。
5.Please tell me how I can use the computer,will you? 请你告诉我怎样使用计算机好吗？(三)由连词wether或if引导的宾语从句。
例如：1.The teacher asked me if/whether I could answer this question.老师问我是否能回答这个问题。
2.We don't know if/whether he has been to The Great Wall.我们不知道他是否去过长城。
二、宾语从句需要注意的几个问题(一)宾语从句是陈述句不是疑问句，要用陈述句语序。
(二)含有宾语从句的复合句主句是过去时宾语从句要用过去时态——一般过去时，过去进行时，过去将来时和过去完成时。
(*但主句是其他时态时，宾语从句根据需要可用任何时态。
)例如：1.He said that he had never seen such an exciting match before.他说他以前从来没有看过这样一场激动人心的比赛。
(主句一般过去时，宾语从句过去完成时)2.I didn't know what her name was.我不知道他叫什么名字。
(主句一般过去时，宾语从句一般过去时)3.I heard that they would play against the girls'team.我听说他们将要和女生队比赛。
(主句一般过去时，宾语从句过去将来时)*当宾语从句是客观真理时，无论主句是什么时态宾语从句都要用一般现在时。
例如：1.The teacher told them that light travels faster than the sound. 老师告诉他们光速比声速快。
2.The little child didn't know the earth goes round the sun. 那小孩不知道地球是绕着太阳转的。
(三)只能用whether不能用if的几种情况：1.whether可以直接和or not连用，if不可。
I don't know whether or not he can pass the exam. 我不知道他是否能通过这次考试。
2.whether引导的宾语从句可放在句首，if不能。
Whether he can go,I'm not sure. 他是否能去，我不肯定。
3.whether还可以引导主语从句放在句首，if不能。
Whether he can pass the exam is till a question. 他是否能通过这次考试仍然是个问题。
(四)think,believe,expect,suppose等动词后面接宾语从句要表达否定意义时，要在主句的谓语动词上来表现。
例如：1.I don't think that hens can swim. 我认为鸡不会游泳。
2.We don't believe that they can finish the work in such a short time. 我们确信在这么短的时间内他们完不成这项工作。
(五)动词think的主语是第一人称时，反意疑问句要根据宾语从句来做。
例如：1.I think that he is right,isn't he? 我认为他是对的，是不是？2.We don't think that it is going to rain,is it? 我们觉得不会下雨，是吗？宾语从句专项练习一、翻译句子.1.恐怕你不能在这儿吸烟。
