考博英语每日一练（8.26）参考答案
1.C
【句意】因为这是一个非常关键的案件，所以做决定时你再谨慎也不为过。
【解析】固定搭配。由句中关键词“careful谨慎的”与“as it was such a critical case因为这是一个非常关键的案件”的对应知可构成固定搭配“can’t be too careful再谨慎也不为过”的C项正确。

2.D
【句意】星系是由其组成部分之间的重力引起的引力维系在一起的，而它的旋转运动阻止了它自身的坍缩。
【解析】形容词和名词词义辨析。gravy“肉汁”；gravel“ 沙砾；砾石；石子”；gravimetric“（测定）重量的；重量分析的”；gravitational“引力的；重力引起的”。由句中关键词“A galaxy is held together by…星系由……维系在一起”和“attraction引力”的对应知“重力引起的”符合语境，故D项正确。
