单选题 Although we tried to concentrate on the lecture, we were ______ by the noise from the next room.
A. distracted B. displaced C. discharged D. discarded

【正确答案】 A

【答案解析】distract意为“转移注意力，分散思想”；displace意为“取代，代替”；discharge意为“清偿债务，履行义务”：discard意为“丢弃，抛弃”。根据although可知，所填之词表示的意思应该与concentrate on的意思对应，并且根据后面的by the noise可知，应选distract。
