题目内容
【题目】Since the general retired from the army, he __________ himself in writing his memories.
A. is devoting B. has been devoted
C. had occupied D. has been occupying
【答案】D
【解析】句意:将军从部队退休后,一直在忙于撰写回忆录。occupy oneself in doing sth. 意为“从事于,忙于,专心于”,符合语境语义。同时注意句子时态表示从过去某个时间开始一直持续到现在的动作,强调的是持续性,用现在完成进行时。A、B、C三项在结构上均存在错误。
