请问 在宾语从句中 that 何时可以省 何时不可以省 要详细的 谢谢
that引导的宾语从句,一般可以省去that,但在下面情况中不能省略——
1.在suggest, order等表示命令、请求、建议等动词后的宾语从句中,不能省；
2.由and或but所连接的两个引导的宾语从句时,第一个从句中的that可以省,第二个从句中的that不能省；
3.that引导的宾语从句,如果从句中还有其他状语从句,引导宾语从句的that不能省略。
Tell him that if he is at home, I'll call to see him.
that引导的主语从句，that什么时候可以省，什么时候不能省呢？
That 引导名词性从句，主，表，同位，宾中只有宾从能省，都不做成分，这是区分that与what的关键。
主语从句：That the earth is round is known to all.
It's known to all that the earth is round.
that的特征，不做成分，无含义，不省略（除宾从外）
定语从句中，先行词做宾语，可以省略that。This is the book (that) I need.
find后面that的用法
find +that +从句
即that引导的宾语从句，find解释为：发现，不能解释为：找到
that后面的宾语从句，要有主语和谓语动词
如 I found that he was sad
