I must have been dreaming. 我没看见。我当时一定是在胡思乱想吧。 She cant have been 29.She must have been 36. 她那时肯定不会是29岁，她一定36岁了。 He cant have been reading. He must have been sleeping. 他那时肯定不是在看书，他准是在睡觉。,2. must和have to的用法 两者都表示必要性，两者的主要区别在于： 1. must表示主观意愿，而have to表示客观事实。 2. must 只用于现在时，而过去时用had to，将来时用will have to。3. must 不用于否定句，否定句用neednt 不必要或dont need to。mustnt的意思是不允许，禁止。,1、I am amazed that the actress married the actor so soon.
