This is his only request that the room after being used.

A. be cleaned

B. would be cleaned

C. is cleaned

D. will be cleaned

答案：

(答案→)A. be cleaned

B. would be cleaned

C. is cleaned

D. will be cleaned

解析：考查虚拟语气。本题是一个同位语从句，前面的名称是request，后面的同位语从句中使用虚拟语气should+动词原形，should可以省略。句意：使用以后这个房间要被打扫干净，这是他唯一的请求。故A正确。
