　　情态动词must与have to

　　概念解释：所谓情态动词就是可以表达一定情感色彩的助动词，这里先行介绍的是must与have to。在表示主观上感到必须去做什么事情时，用must;在表示客观上就必须那么做时，用have to。have to的过去时是had to;must的过去时也是had to。must经常用来表示对某种情况的判断。

　　示例1：She must be at least 35 years old.(表示判断)

　　示例2：Jennifer will have to take part in a new play soon.(表示客观上的必须)

　　示例3：In the play, she must appear in a bright red dress and long black stockings.(表示主观上的必须)

　　示例4：Last year in another play, she had to wear short socks and a bright orange-colored dress.(must的过去时)

　　示例5：Darling, it must be terrible to be grown up.(表示判断)
