求宾语从句的详解

在句子中起宾语作用的从句叫做宾语从句。宾语从句分为三类：动词的宾语从句,介词的宾语从句和形容词的宾语从句。 宾语从句的连接词：(一)、从属连词连接宾语从句的从属连词主要有that,if,whether。that引导表示陈述句的宾语从句,if和whether,whether。。。or not引导表示“是否”的一般疑问句的宾语从句。（二）关联代词连接代词主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等。连接代词一般指疑问,但what,whatever除了指疑问外,也可以指陈述。（三）关联副词连接副词主要有when,where,why,how,whenever,wherever,however等。 宾语从句的用法　　1．that引导宾语从句无意义,不充当句子成分常省略。但下列情况除外：①．介词宾语从句的that不能省略。②． and连接的两个从句,两个从句的that不能省略。He told me that he had two sons and that they both had gone to college。 ③．在动词+it+宾语补足语+宾语从句结构中,that不省略。I heard it said that he had gone abroad We found it impossible that he could finish it in such a short time 2。Whether,if 引导宾语从句：两词可互换,但是下列情形除外：①．whether从句中有or not ②．whether从句做介词宾语 Everything depends on whether you agree with us 3．许多带复合宾语的句子,宾语从句经常移到句子后部,而用it做形式宾语。结构是：主语 + 动词 + it + 形容词/名词等宾语补足语 + 宾语从句 We think it wrong that he told a lie to everyone。 ①．宾语从句的语序要用陈述句语序。False: He is wondering when can he finish this difficult job。Right: He is wondering when he can finish this difficult job。 ②。 有时候可以用it 作形式宾语,而把真正的宾语从句放在后面。Bad: I thought that he could finish this job in just two hours impossible。Good: I thought it impossible that he could finish this job in just two hours。 Bad: He left whether we should continue this project to my judgment。Good: He left it to my judgment whether we should continue this project。③。 带有宾语从句的复合句的否定形式一般是否定主句。Bad: I think he doesn’t like the English teacher。Good: I don’t think he likes the English teacher。④。 主句一般过去时态,从句也要用过去时态；具体细节请看第一部分。False: He wanted to know why he is crying in the corner。Right: He wanted to know why he was crying in the corner。希望可以帮到你。
