【华慧考博】考博英语每日一练(8.28)参考答案
1.B【句意】根据查尔斯·达尔文的说法,增强物种生存能力的随机变化是自然的选择,并且遗传给以后的后代。
【解析】形容词词义辨析题。successive“连续的;继承的;依次的;接替的”;succeeding“随后的,以后的”;relative“相对的;有关系的;成比例的”;relating为动词relate“叙述;使……有联系”的现在分词。由关键词“naturally selected自然选择”与“pass(其动词过去式为passed)on把……传给(下一代)”的对应知“以后的”符合语境,故B项正确。
2.D
【句意】女性的吸烟率在之前可以忽略不计,但是现已发展到如此的程度,以至于肺癌已成为女性癌症相关死亡的主要原因。
【解析】名词词义辨析题。abundance“充裕,丰富”;necessity“需要;必然性;必需品”;impudence“厚颜无耻;粗鲁”;incidence“发生率;影响范围”。由关键词“formerly neglectable之前可以忽略不计的”与“has grown to已发展到”,以及后文谈及“吸烟与癌症相关死亡”综合可知“发生率”符合语境,故D项正确。
