Question

---How clean the window is ! -----Yes ! It _______ just now .

A. has been cleaned  B. was cleaned  C. is cleaned  D.  will be cleaned

 

Answer 1

【答案】

B

【解析】

试题分析：has been cleaned（现在完成时）被打扫过； was cleaned（一般过去时）被打扫了；is cleaned（一般现在时）被打扫；will be cleaned（一般将来时）将被打扫。原句意思是：窗子多么干净啊！是啊，它刚才被打扫了。Just now是过去时的时间状语，本句不能用现在完成时。故选B。

考点：考查动词的时态辨析。
