表示推测的情态动词
在英语中，表示对某件事物的确定程度，即表示推测的时候，我们通常会用到以下情态动词: must, might, could, may, can’t, couldn’t。
意思 推测程度
must 一定，肯定 100%的可能性
may might /could 有可能， 也许 20%---80%的可能性
can’t 不可能， 不会 可能性几乎为零
must表示可能性最大的肯定推测，意思是“一定、准是”。
can表示推测“可能性”时，一般用于否定句或疑问句。can在疑问句中意思是“会，可能”。
could 表示某事有可能发生或可能是事实。
could 还可用于表示客气、礼貌、委婉的请求语气。
may, might表示推测“可能性”时，意思是“可能”，“也许”。might不表示过去时态，语气更委婉，可能性更小。may, might表推测时，可用于否定句，但不用于疑问句。
