請問since and because 有甚麼分別?

Since and because have a same meaning in general ->因為

But since have another meaning->Since 19XX

But now we focus on the meaning of 因為,以顯示因果關係(cause-and-result relationship)

雖然意義上一樣,但係層次上有些少唔同,好明顯since係高層次過because

最重要既分別,在於用法同擺放既位置

有Because of 擺最前面: Because of XXX, YY ZZZ
有Because 擺最前面: BecauseXXX, so/therefore YYZZZ
有Since擺最前面: Since XXX,YYZZZ
有擺中間: The YYZZZ because/since XXX

記住because 只可以係句段(唔一定句子)前面出現既時候加of
係中間既話加of就會差,唔一定錯,但係唔流暢
記住絕對無since of 呢樣野
