求賓語從句的詳解

解答：

在句子中起賓語作用的從句叫做賓語從句.賓語從句分爲三類：動詞的賓語從句,介詞的賓語從句和形容詞的賓語從句.
賓語從句的連接詞：
(一)、從屬連詞
連接賓語從句的從屬連詞主要有that,if,whether.
that引導表示陳述句的賓語從句,
if和whether,whether...or not引導表示「是否」的一般疑問句的賓語從句.
（二）關聯代詞
連接代詞主要有who,whom,whose,what,whoever,whomever,whosever,whatever,whichever等.
連接代詞一般指疑問,但what,whatever除了指疑問外,也可以指陳述.
（三）關聯副詞
連接副詞主要有when,where,why,how,whenever,wherever,however等.
賓語從句的用法　　1．that引導賓語從句無意義,不充當句子成分常省略.但下列情況除外：
①．介詞賓語從句的that不能省略.
②． and連接的兩個從句,兩個從句的that不能省略.
He told me that he had two sons and that they both had gone to college.
③．在動詞+it+賓語補足語+賓語從句結構中,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 引導賓語從句：兩詞可互換,但是下列情形除外：
①．whether從句中有or not
②．whether從句做介詞賓語
Everything depends on whether you agree with us
3．許多帶複合賓語的句子,賓語從句經常移到句子後部,而用it做形式賓語.結構是：
主語 + 動詞 + it + 形容詞/名詞等賓語補足語 + 賓語從句
We think it wrong that he told a lie to everyone.
①．賓語從句的語序要用陳述句語序.
False: He is wondering when can he finish this difficult job.
Right: He is wondering when he can finish this difficult job.
②. 有時候可以用it 作形式賓語,而把真正的賓語從句放在後面.
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. 帶有賓語從句的複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. 主句一般過去時態,從句也要用過去時態；具體細節請看第一部分.
False: He wanted to know why he is crying in the corner.
Right: He wanted to know why he was crying in the corner.
