Question

We were told that Mr Green _____ the office for a few minutes when we arrived.

A．has been away from

B．had left

C．had been away from

D．has left

Answer 1

C

試題分析：句意：有人告訴我們，當(dāng)我們到達(dá)辦公室的時候格林先生已經(jīng)離開好幾分鐘了。由于句子當(dāng)中含有表示一段時間的狀語for a few minutes，故謂語動詞必須用延續(xù)性動詞；leave離開，是一個非延續(xù)性動詞，當(dāng)與一段時間連用時，必須換成be away from。根據(jù)when we arrived可知主句必須是過去時態(tài)，所以選C。
