Will you be going back home for the Spring Festival? (来源：英语杂志 http://www.EnglishCN.com)

False: 是的，我回去。Of course! (这一句是错的)

True: 当然。Sure. / Certainly.(这种说法是正确的)

以英语为母语的人使用of course的频率要比中国的学生低得多，只有在回答一些众所周知的问题时才说of course。因为of course后面隐含的一句话是“当然我知道啦!难道我是一个傻瓜吗?”因此，of course带有挑衅的意味。在交谈时，用sure或certainly效果会好得多。同时，of course not也具挑衅的意味。正常情况下语气温和的说法是certainly not。
