【2019 •襄阳市】— I enjoy walking on the clean streets in the morning.

  — You know they _      by the hard-working cleaners every day.

  A. clean                                    B. are cleaned        

  C. are cleaning                             D. will clean

【回答】

B

【解析】句意：——我喜欢早上在干净的街道上散步。——你知道它们每天都被勤奋的清洁工打扫。考查一般现在时的被动语态。A. clean打扫，动词原形；B. are cleaned一般现在时的被动语态；C. are cleaning现在进行时态；D. will clean一般将来时态。根据You know they _    by the hard-working cleaners every day.可知本句为主从复合句，从句的主语they和谓语动词clean之间存在逻辑上的被动关系，所以应用被动语态；由every day可知句子时态用一般现在时，一般现在时的被动语态构成为am/is/are+动词的过去分词，主语是they，be动词用are，clean的过去分词是cleaned；故*选B。

知识点：动词语态
