【华慧考博】考博英语每日一练(1.21)参考答案
1.D【句意】他等待领导人接见时因激动而心怦怦直跳。
【解析】词义辨析——动词辨析题。flap(其动词过去式为flapped)“拍打;飘动”;flourish“繁荣,兴旺;茂盛”;flush“发红,脸红;冲走”;flutter“振翅;(旗帜等)飘动;(如心脏)不规则跳动”。由题干关键词“with excitement因激动”的对应可知“(如心脏)不规则跳动”符合,由此知D项正确。
2.A
【句意】结果是一场小型的家庭宴会,我们本来不必穿得那么正式。
【解析】语法结构——虚拟语气(Need not have done sth.“本来不需要做某事”)。由句中关键词“As it turned out to be a small house party结果是一场小型的家庭宴会”的对应可推知这里应用虚拟语气来表示“我们本来不必穿得那么正式”,由此知A项“本来不需要打扮”正确;也由此可知分别使用一般过去时态和祈使语气的C项“不需要打扮”和D项“千万不要打扮”不正确。由英语中“must have done sth.肯定做了某事”的否定表达方式一般为“shouldn't have done sth.本来不应该做某事”可排除B项。
