表推测时：MUST 加动词原形表示对现在肯定的绝对性推测；加HAVE DONE表对过去的肯定的绝对性推测当情态动词用时：用于肯定句可表示"必须，非得，偏要"；用于否定句表示“不准，禁止”

一、must表示“必须”、“一定要”1、可用于肯定句、否定句或疑问句；用于否定句时，mustn’t 的意思是“一定不要”、“不能”，而不是“不必”：You must finish it today. 你一定要在今天完成它。2、主要表示现在或将来，但有时(如在间接引语中)也可表过去(=had to)：She asked if she must (had to) leave. 她问她是否一定要离开。3、对于must 开头一般疑问句，若要作否定回答，可用needn’t，不用mustn’t："Must I come over tonight?" "No, you needn’t." “我今晚必须过来吗?”“不必。”4、其后可接被动结构或进行形式：Something must be done to stop it. 必须采取措施来阻止它。二、must表示推测其意为“准是”、“一定是”，注意以下几点：1、通常只用于肯定句，在否定句或疑问句用 can 代之：It must be true. 那一定是真的。比较：Can it be true? 那可能是真的吗? / It can’t be true. 那不可能是真的。2、后接动词原形，表示对现在情况的推测：He must be wrong. 他一定错了。
