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
