【題目】﹣﹣Why not go into the classroom？

﹣﹣The door locked．

A.have beenB.will beC.has beenD.is

【答案】C

【解析】

考查現(xiàn)在完成時(shí)。句意：﹣﹣為什么不進(jìn)教室？﹣﹣門(mén)已經(jīng)鎖了。現(xiàn)在完成是表示“過(guò)去的動(dòng)作對(duì)現(xiàn)在的影響或結(jié)果”或“過(guò)去的動(dòng)作一直持續(xù)到現(xiàn)在”。本題中的門(mén)“已經(jīng)被鎖”，對(duì)現(xiàn)在產(chǎn)生影響是“沒(méi)有進(jìn)教室”，故需要現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)，主語(yǔ)是第三人稱單數(shù)。故選C。
