Question

When they went to the theatre, the play ______ for five minutes.

A．had begun

B．has begun

C．had been on

D．was on

Answer 1

C

考查完成時(shí)態(tài)。句意：當(dāng)他們到達(dá)劇院時(shí)，演出已經(jīng)開始五分鐘了。結(jié)合語(yǔ)境可知在過去某時(shí)之前動(dòng)作已經(jīng)發(fā)生了，故用過去完成時(shí)態(tài)。瞬間動(dòng)詞begin不能和表示一段時(shí)間的時(shí)間狀語(yǔ)for five minutes連用，故選C。
