【題目】—The window is dirty.

—I know. It ___ for weeks.

A.hasn’t cleanedB.didn’t cleanC.wasn’t cleanD.hasn’t been cleaned

【答案】D

【解析】

考查時態(tài)和語態(tài)。句意：——窗戶是臟的�！抑�。它已經(jīng)好幾個星期沒有打掃了。句中it指代window和clean之間是被動關(guān)系，又此處表過去的動作對現(xiàn)在造成的影響，故用現(xiàn)在完成時的被動語態(tài)，主語it是單數(shù)，故用hasn't been cleaned，故選D項。
