如果Must和“ should都表示需要某物,那麼在這句話中可以用mustn't代替shouldn't嗎?

有這種想法是可以理解的。但是,這兩個詞之間實際上存在細微差別。首先,區別在於must是對應該做某事的強烈聲明,而should (尤其是在疑問句中)更像是建議或推薦。換句話說,可以看出must should例子: You mustn't be so rude to him. He won't come back if you do that. (不要那樣對他無禮。他不會回來的。) 示例: Shouldn't you put salt in the food before serving it? (鹽不應該在上菜前先加鹽嗎?) 示例: You must be home by eight tonight! (今晚8點前回來!)
