點解although同but 唔可以擺同一句?

英文同中文唔一樣, 英文有分主句(main clause)  同埋副句(subordinate clause). 而每一句係只可以有一句主句.

所以老師成日講although 同but唔可以擺係同一句就係依個原因. 

Although I was sick today, I still go to school.

有Although 依部分就係副句(subordinate clause)

後面(I still go to school) 就係主句 (main clause).

副句係唔可以自己做一句完整句子, 所以而前都成日聽老師講就咁Because開頭都係錯就係依個原因.

Because I was sick. 就唔係一句完整句子啦. 所以以前考試係咪都會叫你加It is because..... 咁樣先可以叫做一句complete sentence.
