How long have you ()the mobile phone?

Question

A had Bbought C lent Dborrowed. 我认为是选A。因为CD首先肯定不是， 而bought是瞬间动词。可是我们英语书上有一句话是I have already bought the travel guidebook。这是为什么呢？ 现在进行时是不是一定要用瞬间动词呢？

Answer 1

用持续时间做状语来限定的完成时，要使用延续动词，否则就可用瞬间动词,表示动作已完成可是用I have bought it. 但不可用I have bought it since yesterday,只能说I have had it since yesterday.How long have you had the mobile phone?就是以问句的形式用时间限定了，所以只能用延续动词。现在进行时不一定要用瞬间动词，如:I'm buying the book.表示将来时态，意思是：我打算要买那本书。
