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】

試題分析：has been cleaned（現(xiàn)在完成時(shí)）被打掃過(guò)； was cleaned（一般過(guò)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(lái)時(shí)）將被打掃。原句意思是：窗子多么干凈�。∈前�，它剛才被打掃了。Just now是過(guò)去時(shí)的時(shí)間狀語(yǔ)，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。
