1. rise = to move upwards or to a higher position [不及物動詞]The aircraft rose slowly into the sky.意思是:上升但某件物品的價格上升是說成: rise in price或rise in valueMotor fuel rose in price as the war continued.2. arise = to begin to exist or to develop [不及物動詞]We can have another meeting if the need arises.意思是:出現3. raise = to put something in a higher place or positon [及物動詞,會有受詞]He could hardly raise the injured arm at all.意思是:舉起某物件You can raise your prices.你可以提高售價. arise大多以抽象名詞為主詞...

We always considered the use of "To rise" for describing something is increasing or moving up and "to arise" for something is appearing.
