Question

【题目】—How long have you been going to work on foot?

—Since last month when I ________ from a heart attack.

A.recoveredB.have recovered

C.was recoveringD.would recover

Answer 1

【答案】A

【解析】

考查时态。句意：——你步行上班已经多长时间了?——自上个月我心脏病康复开始。last month是过去的的时间点，应该与过去时连用，when引导定语从句，指代last month，指上个月我从心脏病康复。用一般过去时。故选A。
