關於英文文法上的文法--adjective

it is + adj. + that 後面要用名詞先. 就好似要加另一句完整句子上去咁.
例: It is wonderful that you have such a daughter.
'you have such a daughter' 有主語動詞和賓語, 本身已可成為一句句子.

it is + adj + of ...to... of 後面要加一個人或團體. to 後面要加動詞.
例: It is very kind of you to help me sweeping the floor.
it is + adj+for...to... 相類似

後兩者的意思可參考http://hk.knowledge.yahoo.com/question/?qid=7006032600278

xxx for you代表對你來說是xxx e.g. It is very easy for you to boil water.
