考点二.情态动词表示推测的用法
情态动词可用来表示推测,语气从强到弱的顺序是：
must，should，can，may，could，might。
１．must所表示的可能性最大，最有把握，意为“一定”。
２．can和could主要用于否定句和疑问句中 ，can’t或couldn’t 表示“不可能”
３．may 和 might表示现在或将来可能发生的动作或情况，主要用于肯定句中，might相对于may 来说，表示的可能性更小一些。
E.g.
She may not be at home.
She can’t be at home.
They should be there right now.
情态动词+do-----表示对现在或将来的情况的推测
情态动词+be doing。 ---------表示对正在进行的情况的推测
must/may/might + have done --------表示对过去情况推测 (肯定，可能，也许已经…)
