【华慧考博】考博英语每日一练（12.20）参考答案
1.A【句意】除了她的工资外，她还从投资中获得附带收益。
【解析】形容词辨析题。subsidiary“附属的；辅助的；补贴的；附带的”；subjective“主观的；个人的”；accidental“意外的；偶然的”；supervisory“监督的”。由关键词“In addition to her salary除了她的工资外”和“investments投资”知“附带的”符合，由此知A项正确。
2.A
【句意】计算机模拟表明原始的盘古大陆（Pangaea）岛屿的气温在一年中常常波动，这逐渐削弱了古生物学家们对该岛屿上气候稳定的假设。
【分析】动词辨析题。undermine“渐渐破坏；逐渐削弱”；confirm“确认；证实”；bolster“ 支持；支撑”；challenge“向……挑战；对……质疑”。由句中关键词“Paleontologists’ assumptions about the equable nature of the climate on the primeval island of Pangaea古生物学家们对原始的盘古大陆（Pangaea）岛屿上气候稳定的假设”与“computer simulations indicating that the island’s temperatures tended to fluctuate during the course of a year计算机模拟表明原始的盘古大陆（Pangaea）岛屿的气温在一年中常常波动”的对应知“逐渐削弱”更符合语境，应该选择A。
