选择题
--- When did you buy this computer? It looks so new.
--- I it for only a couple of days. My sister bought it for me as a birthday present.
A．bought
B．have bought
C．have had
D．had
答案
答案：C
题目分析：句意:-你什么时候买的这台电脑？它看起来很新。-我才买了几天。我的姐姐作为生日礼物
买给我的。buy 买，是一个动词。根据句意可知，这台电脑已经买了，而且至今为止已经有几天了，故应该用现在完成时态。并且buy是瞬间性动词，不能和一段时间连用，而句中有for a couple of days，故B不对，选C。A和D是一般过去时。
