用must\need\may开头的疑问句回答的肯定和否定回答形式是什么?

答:如何回答以must,may,need等开头的疑问句—Must I do it at once?—No,you ____ .A.mustn't B.needn't C.can't D.don't此题应选B。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.当然可以。—No, you may not.不行。(语气较生硬)—You'd better not.最好不要抽。—I'd rather you didn't.还是不抽的好。—Please don't.请不要抽。3.—Need I finish it today?我必须今天完成它吗?—Yes, you must.是的,今天必须完成它。(肯定回答不能用Yes,you need,因为情态动词need 只用于否定句或疑问句,不用于肯定句)—No, you needn't.不必今天就完成它。—No, you don't have to.不必今天就完成它。
