【华慧考博】考博英语每日一练(8.19)参考答案
1.C【句意】这趟火车刚一启动,就听到一声巨大的爆炸声。
【解析】语法题——倒装句。由“英语中固定搭配‘hardly…when一……就……’在使用时,如果hardly放在句首,when前面的句子需要部分倒装”可直接排除A项与B项;再由“从句的时态是过去式,且主句动作发生在从句的动作之前。”知这里的主句要用过去完成时态,故C项正确。
2.D
【句意】几个世纪以来,尼罗河和沙漠的沙子都以难以察觉的方式移动着,然后这座寺院从世界上消失了,直到1813年,其才被瑞士探险家吉恩·路易斯·伯克哈特重新发现。
【解析】副词词义辨析题。imperceptibly“极微地;微细地;难以察觉地”;enormously“巨大地;非常地,在极大程度上”;unstably“不稳定地”;progressively“渐进地;日益增多地”;unnoticeably“不引人注意地;不显著地;不易察觉地”。由关键词“the Nile and the desert sands尼罗河和沙漠的沙子”及“shifted移动”的对应可推知imperceptibly在这里有“难以察觉地”的意思,故D选项“不易察觉地”正确。
