表示推測的情態(tài)動(dòng)詞在英語中，表示對某件事物的確定程度，即表示推測的時(shí)候，我們通常會(huì)用到以下情態(tài)動(dòng)詞，must,might,could,may,can’t,couldn’t.

情態(tài)動(dòng)詞must,might,could,can’t后面都接動(dòng)詞原形，都表示對現(xiàn)在情況的揣測或推斷，但它們的含義有所不同：must

一定；肯定(100%的可能性)might有可能；也許(20%~80%的可能性)can’t不可能；不會(huì)(可能性幾乎為零)例如：1.Thedictionarymustbemine.Ithasmynameonit.

這本字典一定是我的。它上面寫有我的名字。2.TheCDmight/couldbelongtoTonybecausehelikeslisteningtopopmusic.
