请问哪些用that引导的从句that可省,或不可省,如介词后面跟that 从句

请问哪些用that引导的从句that可省,或不可省,如介词后面跟that 从句
1)that引导宾语从句,在句中不做成分,用作连词,通常可略
2) 引导主语从句,在句中不做成分,用作连词,通常不略
3) 引导同位语,表语从句,不做成分,不能略
4) 引导定于从句,必做成分,做主语时不能略,宾语可以略

可省that的从句,原则是that 在从句中只起连接作用,不代替任何成分,主要用于部分的宾语从句,定语从句,而在that省略之后也不会造成对句意的误解。
例如:
It's time (that) we left. (定从)我们该走了。
That's the way (that) I study English.(定从)
I'm sure (that) you'll ...

可省that的从句,原则是that 在从句中只起连接作用,不代替任何成分,主要用于部分的宾语从句,定语从句,而在that省略之后也不会造成对句意的误解。
例如:
It's time (that) we left. (定从)我们该走了。
That's the way (that) I study English.(定从)
I'm sure (that) you'll pass the exam. (宾从)
不可省that的从句,
1) 习惯用法,不省略。
2)因为that代替句中的某个词而作某个成分时,在that省略之后,句意不明确。
3)固定搭配,不能省。
例如:
The degree that water freezes is called freezing point, isn't it? (定从)
It is necessary that every one of you practices speaking English every day.(主从)
We have the conclusion that one can't learn anything without his own practice.(同位语从句)
My suggestion is that he should ring her up right away.(表从)
You'd better take the umbrella with you for fear that it should rain. (目的状语从句)
Atoms are so small that we cannot see them at all. (结果状语从句)
