.sure 的主语只能是人,certain的主语人或物均可.
I am sure of(相信) it. I am sure that she will be here on time.(相信). He is sure to arrive on time.(一定).以上三句均可用certain代替.
2.It is certain that-clause,不可以用sure.如:It is certain that more and more Chinese are learning English, and that not all can go further.
3. John sure is living in Shanghai now.sure 用在任何谓语动词之前,意义为确实.
