Question

【题目】—I knocked at the door of your house at 9:00 yesterday morning . But nobody answered me.
—Oh, I ________a walk with my parents at that time .
A.take
B.was taking
C.took
D.have taken

Answer 1

【答案】B
【解析】句意：—昨天早上9点我敲了你家的门。但是没有人回答我。—哦，那时我正和我的父母一起散步。由yesterday morning可知，对话的时态用过去时；再由at that time“当时”可知此时的动作正在进行。因此用过去进行时态。故选B。
