问题
选择题
—I called you at 5:00 yesterday afternoon, but no one answered.
—Sorry, I with my parents ________ at that time.
A．was shopping
B．were shopping
C．are shopping
D．went shopping
答案
答案：A
题目分析：— 我昨天下午五点给你打电话了，但是没人接。— 对不起，那时我正陪着妈妈买东西呢。通过以上分析可知，应该用过去进行时；本句I是主语，with my parents是介词短语做定语，不是主语，所以后面用was。故选A。
