Let'snotplayonthestreet.二、情態(tài)動詞must，can，could表示推測1.情態(tài)動詞can和could用于表示對現(xiàn)在或將來的推測，意為“會，可能”，往往用于否定句和疑問句中，用于疑問句時，can比could表示的“可能性”要大；用于否定句時，cannot(can't)表示“不可能”。could則可用于肯定句、否定句和疑問句。在以下例句中，can和could均表示可能。如：

Itcouldbeafraid.

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

Youmustbetiredafteraday'swork.
