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

B

解析試題分析：has been cleaned（現(xiàn)在完成時(shí)）被打掃過； was cleaned（一般過去時(shí)）被打掃了；is cleaned（一般現(xiàn)在時(shí)）被打掃；will be cleaned（一般將來時(shí)）將被打掃。原句意思是：窗子多么干凈��！是啊，它剛才被打掃了。Just now是過去時(shí)的時(shí)間狀語，本句不能用現(xiàn)在完成時(shí)。故選B。
考點(diǎn)：考查動(dòng)詞的時(shí)態(tài)辨析。
