Do you feel cold vs Are you cold?

首先Do係一個verb to do，而Are係verb to be(is,am,are)

而當你用verb to do(do,does,did)個陣，後面一定要係一個verb(動詞)

而當你用verb to be(is,am,are,was,were)個陣，後面就一定要係一個名詞(noun)或者形容詞(adj.)

而Do you hot vs Are you hot的話，當然就Are you hot勝la，因為hot係形容詞(adj.)

而Do you hungry vs Are you hungry，當然都係Are you hungry勝la，因為hungry係形容詞(adj.)。

用do 做開頭問問題既時候後邊會係有個verb 的...
用are 的話, 就會係noun or adjective~

therefore, do you hot 同do you hungry 都係錯的!!
