题目内容
---What a nice MP3! How long ______ you ______ it? ---Only two days.
| A．have, bought | B．did, buy |
| C．have, had | D．are, having |
C
解析试题分析：句意：多么好的一个MP3。你买这个多久了？仅仅两天。现在完成时可以用来表示发生在过去某一时刻的,持续到现在的动作（用行为动词表示）或状态（be动词表示）常与for（+时间段）,since（+时间点或过去时的句子）连用. 现在完成时中，非延续性动词不能与for和since引导的表示一段时间的状语连用，通常是用相应的延续性动词来代替。buy 对应的延续性状态词是have。故选C
考点：考查现在完成时态的用法。
