题目内容

15．Our classroom every day．（　　）

A．

clean

B．

cleans

C．

cleaned

D．

is cleaned

分析我们的教室每天都打扫．

解答答案：D．考查被动语态．句意"我们的教室每天都打扫．"．A动词原形．B第三人称单数．C过去式．D被动语态．主语classroom，动作的承受者，因此用被动语态，结构是be动词+动词的过去分词．every day每天，一般现在时态，主语是单数，因此用be动词单数is．clean的过去分词是cleaned．故选D

点评被动语态表示主语是动作的承受者，被动语态由"be动词+及物动词的过去分词"构成，be动词的单复数要与主语的单复数保持一致，还要注意时态及过去分词的变法．
