哪些宾语从句后不能省略引导词that？

Question

如题所述

Answer 1

that引导的宾语从句只是起连结作用,本身没有意义,在口语或非正式文件中可以省略.
例: She said (that) she was going to study French. 她说她准备去学法语.

提示:
1.如果谓语动词后跟有两个或更多个并列的宾语从句, 第二个(和第三个)连接词不可省略.
例: I forgot (that) my research paper was due on Tuesday and that my teacher had said he would not accept late papers.
2.主句中有it作形式宾语, that不可省
例: We think it is important that every citizen should have good manners.
3. 宾语从句的第一个词为this/ that时, 引导词that不可省
例: She told me that that night was very cold. 她告诉我,那个晚上很冷.
4. in that, except that后接宾语从句时,引导词that不可省
例: Criticism is necessary in that it helps to correct our mistakes.

Answer 2

在宾语从句中，that不作成分，所以都能省略。

Answer 3

1.两个或两个以上由that引导的宾语从句，只能省略第1各that，其它的不能省略。
2.
介词后的that引导的宾语从句不可省略。
3.
