You must eat and drink here.(否定句)
You needn't eat and drink here.
ps:
must的否定形式有三种:
must做“应该”讲(表“义务性”),否定形式是mustn't,表示不应该.
must做“准是”讲(表“推断性”),否定形式是can not,表示不可能.
must做“必须”讲(表“必要性”),否定形式是need not,表示不必要.
请计较以下两个句子体会一下mustn't VS needn't:
You mustn't do that again next time.
下次你不可再做这种事了.
You needn't hand in your exercise-book tomorrow.
明天你不必交练习本.
