20點!!!adjective pattern

It is + adj + of/for sb + to-inf.

如果adj指sb就用of
如果adj指to-inf就用for

It is easy for you to finish the task.
To finish the task is easy for you.

It is greedy of him to take it away.
He is greedy to take it away.

乜係錦樣分嫁咩? 同我學校教既有d出入

我學校就話
of 就係講關於一個人既品格, 角色, 性格之類果d, personality果陣用
例如: generous, kind, selfish, silly, intelligent 等等,呢d用of
唔係personality就用for

你舉既果d for既例子: easy, essential, hard, important 等等
呢d唔係人既性格或者角色, 所以就用for

希望解答到你既問題

有方法分架!


It's + adjective + for + 人物A/物件A + to infinitive (action A)指做左Action A後對人物A/物件A有好會有adjective所形容的影響
e.g. It's good for you to drink more water.
飲多D水對你有好處


It's + adjective + of + 人物B/物件B + to infinitive (action B)

指人物B/物件B做左Action B後對你有adjective所形容的影響
e.g. It's good of you to do the setup.
你做好D setup, 你真好.

唔係太關事的^^ 即係:

It's + adjective + for + 人物A/物件A + to infinitive (action A)既Adjective係形容件事
e.g. It is good for you to sleep early.
早訓對你好
It is easy for us to forget things.
唔記得野對我地黎講係好容易的事
