2、表示否定的推测时,只能用cant,意为“根本不可能;肯定不是”。The hair band cant be Bobs because he is a boy.情态动词 must,may,might,could,may,can 表示推测含义与用法后面都接动词原形,都可以表示对现在情况的揣测和推断但他们含义有所不同。must 一定,肯定(100%可能性)may,might,could 有可能,也许(20%、80%可能性)cant 不可能,不会(可能性几乎为零)如:The dictionary must be mine.It has my name on it.The hair band cant
