在英語中，All don't不等於No do的意思

Not all of them are agreed by me.

I don't agree all of them.意思是「我並不是同意所有的東西」

而

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

當不定代詞做賓語時，不能把not提前，但not all仍然表示部分否定

——我們老師說的

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.
