must ,might ,could ,can't的用法?
一般而言,must表猜测只用于肯定句,表示肯定的猜测.对于正在进行的事的推测用must be doing 对于已经发生过的事的猜测用must have done
might表猜测不用于疑问句,对于时态与上面的表达一致,只用将must改成might
could可用于一切（肯定否定疑问句),时态与上面类似,但是could have done除了对表示发生过的事情的猜测“可能做了什么”这个意思之外,还有一个常用的意思,“本可以能够做什么”言外之意是对于能够做的事却没有做
can表猜测不能用于肯定句

全加动词原形

这些都是情态动词，后面都跟动词原形。must可以表示肯定推测，might表示不太确定的推测，大概、或许，could 用于委婉的语气过去式、can't语气生硬一些。

全部都是虚拟语气后面全部加动词原形。
must do sth, might do sth, could do sth, can't do sth.
