宾语从句在复合句中做主句谓语的宾语

1、宾语从句在复合句中做主句谓语的宾语，将这个句子叫做宾语从句。宾语从句做介词或及物动词的宾语。现在从下列三个方面总结归纳如下：一，引导词A,由that 引导的陈述句性的宾语从句，在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后。连词that只起连接作用，在从句中不做句子的成分，也无词汇意义，在口语中常被省略。例：I told him that he was wrong.1 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

2、，而将think 等动词变为否定形式。例：I dont think you are right. (我认为你做的不对)2. 在许多带有复合宾语的句子中，that引导的宾语从句经常移到句子的后面，而用it做形式宾语。例：We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的)3. 如果有多个that引导宾语从句，第一个that可以省略，其他一般不可以The doctor told me (that) I should drink more water and that things would get better ve

3、ry soon.B,一般疑问句用做宾语时，由连词if、 whether 引导，表示“是否”Whether,if 在从句中不做句子的成分，一般情况下，whether和if 可以替t换。例：I dont know if/whether he will come tomorrow.The teacher asked if/whether we had finished the experiment.L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。2.宾语从句中有or not时不用if引导.例：I dont

4、know whether the movie star will come or not.3.和不定式连用作宾语时不用if引导.例：Whether to go there or not hasnt been decided.4. Whether引导的宾语从句可以放在句首：Whether they will join the football match I dont care.C,特殊疑问句用作宾语从句时，用原句的连接代词who,whom,whose, what, which和连接副词when, where, why, how 等连接的宾语从句，它们在句中即有连接从句的作用，又在句中充当句子的

5、成分。例：Do you know which film they are talking about? (which做定语)I dont know where he lives. (where 做地点状语)Do you know whose child he is?Do you remember what you should do next ?I dont know whom they are speaking to.Please tell me who called just now.二.宾语从句的语序，宾语从句从句的语序必须是陈述语序，既连接词+主语+谓语+其他成分例：I believe

6、 that they will come soon.He asked me whether I was a teacher.They wanted to know what they can do for us.三 宾语从句的时态。宾语从句的时态受主句的限制，1. 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。例:1)She says that she is a student.She said that she was a student.2)She says that she will fly t

7、o Japan in a week.She said that she would fly to Japan in a week.3)She says that she has finished her homework already.She said that she had finished her homework already.4)She says that she can sing a song in English.She said that she could sing a song in English.2. 如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一

8、般现在时态。例：The teacher said that the earth goes round the sun.He told me that Japan is an island country.3Could you tell me是用来征询对方的意见，语气委婉，并不表示过去。例：Could you tell me when we will visit the Histury Museum?四注意事项：由陈述句变成宾语从句时，要注意人称的变化。例：She said: “I have been to England before.”She said that she had been to England before.She asked me: “Do you like maths?”She asked me if I liked maths.u宾语从句与简单句的交换。由连接代词和连接副词引导的宾语从句，如果宾语从句的主语和主句的主语是同一个人时，可以用“疑问词+不定式由连接代词和连接副词引导的宾语从句，”做
