can、may、must开头的问句，肯定和否定分别怎么回答
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：
—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。
—Yes,
you
may．当然可以。
—Of
course
you
may[can]．当然可以。
—No,
you
may
not[mustn't，can't]．不行。（语气较生硬）
—You'd
better
not[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。
—Yes,
you
must[have
to,
should]．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。
