一般说来，以must 引出的一般疑问句，其否定回答通常是用 needn't（=don't have to），这与其说是一个语法问题，不如说是一个语境或上下文是否通顺的问题。
注意以下各组问答句，并注意体会其汉语译文：1．—Must I come before dawn？我必须天亮前来吗？—Yes, you must．是的，必须天亮前来。
—No, you needn't．不必天亮前就来。
—No, you don't have to．不必天亮前就来。
2．—May I smoke in the room？我可以在这个房间抽烟吗？—Yes, you may．当然可以。
—Of course, you may[can]．当然可以。
