【华慧考博】考博英语每日一练（9.19）参考答案
1.D【句意】如同我提及的那样，心脏手术是近年来所发展的一种令人惊异的新的外科手术方法。
【解析】语法题——介词as引导比较状语。由关键词“I have already mentioned我提及”与空格前句子句意的对应知这里需填写一个词来构成比较状语，由此知四个选项中D项“如同”正确。
2.B
【句意】政府高级官员一定已经默许了这种掩盖。
【解析】固定/词组搭配。acquire“获得；取得；学到；捕获”，其为及物动词，不与“in”构成搭配；acquiesce“默许；顺从”，acquiesce in sth.“默许/默认某事”；require“需要；要求；命令”；其为及物动词，不与“in”构成搭配。由句中关键词“in”、“cover-up掩盖；隐蔽”的对应以及词义辨析知“默许”符合语境，故B项“一定已经默许”正确。
