问题 Last year, the crime rate in Chicago has sharply______.

选项 A、declined
B、lessened
C、descended
D、slipped

答案 A

解析 decline意为“下降,减少”,如:Domestic production of oil will continue todecline.(国内石油生产将继续下降。)与rate连用表示比率下降。lessen意为“缩小,减少”,不能与rate连用。descend意为“位置下降”,如:He descended into a cellar.(他走下地窖。)slip意为“滑倒”,如:She slipped on the wet stones and fell.(她在潮湿的石头上滑了一下跌倒了。)
