在英語中，表示對某件事物的確定程度，即表示推測的時候，我們通常會用到以下情態(tài)動詞:1.must2.might,could,may3.can’t,couldn’t【注意】1.情態(tài)動詞不能表示正在發(fā)生或已經發(fā)生的事情，只表示期待或估計某

事的發(fā)生。2.情態(tài)動詞沒有人稱、數的變化，即情態(tài)動詞第三人稱單數不加-s。3.情態(tài)動詞沒有非謂語形式，即沒有不定式、分詞等形式。Grammar情態(tài)動詞表推測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表示推測“可能性”時，一般用于否定句或疑問句。can在疑問句中意思是“會，可能”。eg：Hecan’tpickherschoolbagup.他不可能拿了她的書包。could表示某事有可能發(fā)生或可能是事實。eg：Don’teatit.Itcouldgobad.不要吃它，可能壞了。Theplanecouldbeputoffbythestorm.這趟飛機可能會因為暴風雨而

推遲。Grammar3.may/mightmay,might表示推測“可能性”時，意思是“可能”，“也許”。might不表示過去時態(tài)，語氣更委婉，可能性更小。may,might表推測時，可用于否定句，但不用于疑問句。eg：Hemay/mightnotbeathome,butI’mnotsure.

他可能不在家，不過我也不確定。Grammar情態(tài)動詞表示推測可以分為以下幾種情況:(1)情態(tài)動詞+do

此結構表示對現(xiàn)在或將來正在進行的情況的推測和判斷。
