在英语中，All don't不等于No do的意思

Not all of them are agreed by me.

I don't agree all of them.意思是“我并不是同意所有的东西”

而

I don't agree none of them.才意思是：我不同意所有的东西

当不定代词做宾语时，不能把not提前，但not all仍然表示部分否定

——我们老师说的

Not all people like studying. = All people don't like studying.

也是部分否定。

No people like studying.

This pen isn't suitable for all people.

This pen is suitable for no people.
