C.is being cleaned D.was cleaned 

A

解析試題分析:句意:看多么干凈的廁所。是的,它每天上午都被清理。動(dòng)作的承受者作主語(yǔ),用被動(dòng)語(yǔ)態(tài)。其結(jié)構(gòu)是,主語(yǔ)+be+done.主動(dòng)語(yǔ)態(tài)有的時(shí)態(tài)被動(dòng)語(yǔ)態(tài) 也有,時(shí)態(tài)體現(xiàn)在be的變化上。every morning,表示經(jīng)常性,故用一般現(xiàn)在時(shí)。故選A。
考點(diǎn):考查被動(dòng)語(yǔ)態(tài)的時(shí)態(tài)。
