【华慧考博】考博英语每日一练（10.11）参考答案
1.B【句意】尽管经济衰退经常以至少连续两个季度的GDP（国内生产总值）下滑为特征，但是这不是一个固定的规则。
【解析】形容词词义辨析。falling“下降的；落下的”；declining“下滑的；衰退的；倾斜的”；fluctuating“波动的；变动的”；impending“即将发生的；迫切的；悬挂的”。由关键词“recession经济衰退”及“GDP国内生产总值”可知“下滑的”符合，故B项为正确答案。
2.C
【句意】直到很久以后，她才怀疑自己是否犯错了。
【解析】语法题—强调句。由“强调句的基本结构：it is (was)+被强调的部分+that+句子的其他成分”和“当含not until的句子强调时间状语时，必须将not until放在一起”知正确答案为C。
