他一定会来 He is sure to come. 那一定不是刘老师 That person can't be Teacher Liu. 一定要掌握英语 You must command English. 你一定喜欢她 You must have fallen in love with her. You must like her.这种表达方法容易引起歧义。可以理解成父母包办婚姻时逼婚的说法，也可以理解成推测的说法。 你一定没吃过这道菜。You couldn't have tasted this dish.有的时候还可以在后面加上点东西，变成You couldn't have tasted this dish，I bet. 昨天你一定没去学校 You definitely didn't go to school yesterday. 或 You couldn't have gone to school yesterday. 他一定还没来,别着急 Take it easy. He can't have been there. 英语里面确实还有一些词表示很肯定的意思，如bet，absolutely，definitely，exactly等
