---- Is it high time that we _____ on the school building? ---- Yes, it _____. A．do some repairs; is B．do some repair; is C．did some repairs; is D．did some repair; was

Answer 1

C

在It is high time that…句型中，所跟的that引导的定语从句应该用虚拟语气，谓语动词应该用过去式，所以排除A、B选项。do some repairs和during repairs中常用repair的复数形式，但常说beyond repair, in good/bad repair, out of repair, under repair。
