Let'snotplayonthestreet.二、情态动词must，can，could表示推测1.情态动词can和could用于表示对现在或将来的推测，意为“会，可能”，往往用于否定句和疑问句中，用于疑问句时，can比could表示的“可能性”要大；用于否定句时，cannot(can't)表示“不可能”。could则可用于肯定句、否定句和疑问句。在以下例句中，can和could均表示可能。如：

Itcouldbeafraid.

Can/Couldthisbetrue?2.表示有把握的推测时：肯定句用must，意为“一定，准是，肯定”，通常只用于肯定句。否定句用can't，意为“不可能”。如：
