喜樂美語
  1. 1

    Mustn't is the short spoken form of must not. You use it when something is not allowed, or when you want to warn someone strongly: you mustn't touch that; you mustn't tell. It is not the same as don't have to. Don't have to means there is no need — you may skip it. Mustn't means no: do not do it. British classrooms care a lot about that pair. American speakers use must not a bit less, and often say can't for the same “not allowed” feeling. The first t in mustn't is usually silent: it sounds like MUSS-unt. You keep the in writing.

    不可以、不准（must not 的縮寫；不是「不必」）
