It is certain that the temperature will rise.氣溫一定會上升。
He is certain to come.他一定會來。
sure“確信的，無疑的”，作此義解時，主語常為人而不是物。如：He is sure to succeed.他一定會成功。

試比較：They are certain/sure to succeed.他們一定會成功。They are certain/sure of success.他們有成功的把握。第一例用不定式表示說話人對某事的推斷，有“一定，必然”的含義；第二例用of短語表示主語本人的信念，有“確信，對...有把握”的含義。
再如：The strike is certain/sure to take place.罷工必然會發(fā)生。They are certain/sure of victory.他們確信會獲得勝利。
