C．is being cleaned	D．was cleaned

Answer 1

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，用被動(dòng)語態(tài)。其結(jié)構(gòu)是，主語+be+done.主動(dòng)語態(tài)有的時(shí)態(tài)被動(dòng)語態(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)語態(tài)的時(shí)態(tài)。
