Question

Up to now, thousands of red phone boxes, the old image of Britain, ________ due to mobile phones.

A．removed B．have removed

C．were removed D．have been removed

 

Answer 1

D

【解析】答案：D　考查動詞時態和語態。根據時間狀語up to now通常與現在完成時連用，故排除A、C兩項；主語“thousands of red phone boxes”與動詞remove之間構成動賓關系，所以用現在完成時的被動形式。故選D項。
