考博英语每日一练(9.4)参考答案
1.B
【句意】我们在六点钟将会离开,希望到午饭时间时已完成旅程的大部分。
【解析】语法结构——完成时态。由句中关键词“by lunch time到午饭时间时”的对应可知这里应该使用完成时态,由此可直接排除A项和C项;再由这里指代“完成旅程的大部分”知B项“to have done”正确。
2.A
【句意】六个阿拉伯国家与美国中断外交关系,而黎巴嫩撤回了自己的大使。
【解析】词组辨析。break(其动词过去式为broke) off “中断;突然停止”;break up“分裂;分手; (会议、聚会) 解散”;break down“ (机器、车辆等) 出故障;分解; (对观点、陈述等) 分门别类”;break in“打断;闯入”。由关键词“diplomatic relations外交关系”的对应知“中断”符合语境,故A项正确。
