情态动词的回答
我上网查了的 ：must和need相同:Yes,...must.No,...needn't/don't have to
may和can could相同:Yes,...may/can/could.No,...mustn't/...'d better not/can't.
shall:Yes,...can/may.No,...can't.
should:Yes,...should.No,...shouldn't.
will和would差不多:Yes,...do/will.No,...won't/thanks.
但有时must否定回答好像也可以用can't
情态动词的回答我上网查了的 ：must和need相同:Yes,...must.No,...needn't/don't have tomay和can could相同:Yes,...may/can/could.No,...mustn't/...'d better not/can't.shall:Yes,...can/may.No,...can't.should:Yes,...should.No,...shouldn't.
具体判断情态动词和问句,应该要根据上下文的具体语境.语气本身是一种很微妙的东西,所以不是光记一些规则就可以的,一定要看上下文.must的否定回答用can't你有例句吗?我想到的是下面的情况,但这不是疑问句啊,你参考一下吧.
must解释为必须的时候,否定句用needn't,don't have to
must解释为“必然”表示猜测时,否定句用can't,
如：My mother must be angry.-- No,she can't be.
They must have gone out.-- No,they can't have been.
表示猜测的疑问句也用can:Can his story be true?他的故事会是真的吗?
must 表示“必须 一定”，是必须要做的事情，着重于主观的看法（愿意，命令）
而must也不像have to那样有 更多的时态。
need "需要"，表示有这个需要和必要去做某事。need做情态动词时主要用于疑问句，否定句。
差别就在于语气婉转的程度
情态动词 can must
can: I can skate.翻译：我会技能。
must:You must come in time. 你必须在规定时间内到达。
