问题
Despite their lack of success so far, research scientists have ______ in their research for a cure for AIDS.
选项
A、maintained
B、retained
C、insisted
D、persevered
答案
D
解析
动词词义与搭配题。四个选项都有“坚持”或“保持”之义,句首的Despite引导让步状语从句,可知其后的主句应表“科学家们坚持研究”,且该词还必须能与in搭配,故D正确。maintain是及物动词,表示“维持,继续”;retain也是及物动词,表示“保持,保留”;insist表示“坚持,强调”,与on搭配使用。
