Question

—I called you yesterday evening, but nobody answered. Where were you then?

—Oh, I ________ my pet dog in my yard. I ________ this dog for two months.

A.was walking; have had B.walked; have bought C.was walking; have bought

Answer

A

【解析】

句意：——我昨晚给你打电话了，但是没人接。你当时在哪儿？——哦，我当时正在院子里遛狗。我已经买这只狗两个月了。

考查动词时态。was walking过去进行时；have had现在完成时；walked一般过去时；have bought现在完成时。根据前文“Where were you then”和语境，可知第一空要用过去进行时；第二空与for two months连用，可知用延续性动词的现在完成时，bought是buy的过去分词，是瞬间动词，其延续性动词为have，故选A。
