【华慧考博】考博英语每日一练（2.27）参考答案
1.A【句意】这艘船的发电机出了故障，水泵的运转不得不用手动方式来替代机械方式。
【解析】副词词义辨析。manually“手工地，手动地”；artificially“人工地，人为地，不自然地”；automatically“自动地，机械地，无意识地”；synthetically“综合地，合成地”。由关键词generator broke down“发电机出了故障”及instead of mechanically“代替机械地”知“手动地”符合语境，由此知A项正确。
2.D
【句意】约翰不是任意地挑选的，他被选为这项工作的候选人是因为他最有经验。
【解析】副词辨析题。deliberately“ 故意地；谨慎地；慎重地”；alternatively“非此即彼；二者择一地”；momentously“重大地”；arbitrarily“任意地；随意地；武断地”。由句中关键词“he was chosen for the job because he had the most experience他被选为这项工作的候选人是因为他最有经验”的对应知“任意地”符合语境，故D项正确。
