典型例题
例1答案 C 分析：表示否定的猜测用can’t 。must表示推测时，意为“一定”，只能用于肯定句，而must的否定must not（mustn't）表示“不应该”、“不许可”、“不准”、“禁止”等。
例2答案 C 分析：在回答带有must的问句时，否定式常用need not (= needn't)，表示“不必”，而不用must not，因为must not表示“不可以”。
例3答案 D 分析：本题第一句是请求对方的允许，需要用May，其否定式为mustn’t。
例4答案A。对于以情态动词must提问的疑问句，否定回答要用“No, 主语+needn’t”，故由问句中的must和答句中的No可选A。
