I said it would start a bad habit and that she should do her own work中为什么要用that?

问题描述:

I said it would start a bad habit and that she should do her own work中为什么要用that?
said后不都是宾语吗?and后面为什么还用that?

这是两个宾语从句,完整的是I said (that) it would start a bad habit and that she should do her own work
一句话中如果有两个宾语从句,那么第一个that可以省略,而第二个不可以省略
