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:1.must2.might,could,may3.can’t,couldn’t【注意】1.情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某

事的发生。2.情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。3.情态动词没有非谓语形式，即没有不定式、分词等形式。Grammar情态动词表推测1.Shecanplaysthepiano.2.Mr.Licouldisathome.3.Theydon’tcanspeakJapanese.

他肯定知道答案。

Hecan’tknowtheanswers.

他肯定不知道答案。Grammar2.can/couldcan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”。eg：Hecan’tpickherschoolbagup.他不可能拿了她的书包。could表示某事有可能发生或可能是事实。eg：Don’teatit.Itcouldgobad.不要吃它，可能坏了。Theplanecouldbeputoffbythestorm.这趟飞机可能会因为暴风雨而

推迟。Grammar3.may/mightmay,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。eg：Hemay/mightnotbeathome,butI’mnotsure.

他可能不在家，不过我也不确定。Grammar情态动词表示推测可以分为以下几种情况:(1)情态动词+do
