宾语从句中不省略that的七种情况

Question

详细点哈

Answer 1

1. 宾语从句具有陈述意义时用that引导。that无具体意思，不作任何成分，因此在口语或非正式文体中常常被省略。如：
She said (that) she would leave the book on his desk. 她说她会把那本书放在他的桌子上。
● 从句的主语是that时，that不能省略；主从句之间有插入语时，that不能省略；若出现两个或两个以上的that宾语从句，且由并列连词连 接时，只有第一个连词that可以省去，其余保留。如：
It says here, on this card, that it was used in plays.卡片上写着，它过去是演戏用的。
He thought that that was a washing machine. 他认为那是一台洗衣机。
My aunt said (that) she would come and that she would also bring her daughter. 我姑姑说她要来，还要带她的女儿来。
