All the preparations for the task _____, and we’re ready to start.
A.completedB.complete
C.had been completedD.have been completed

試題分析:句意:所有為這項任務的準備工作都已經(jīng)完成了,我們就準備開始了。結(jié)合語境可知本句描述的是現(xiàn)在已經(jīng)完成的動作,故用現(xiàn)在完成時態(tài),任務是被完成的對象,故用被動語態(tài)。選D。
點評:英語中的時態(tài)主要是借助于時間狀語與上下文語境來進行判斷。解答此類題型,首先要注意句子中的時間狀語,如果沒有則要通過分析上下文,結(jié)合語境來判斷句子的時態(tài)。語態(tài)的判斷主要是確定句子主語與謂語動詞的關系。如果是主動關系則用主動語態(tài),反之如果是動賓關系,則用被動語態(tài),尤其要注意一些特殊動詞的用法。
