剑桥国际教育宾语从句的用法总结

剑桥国际教育给大家分享宾语从句的一些用法

一、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

二、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

三、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.

　　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。
