B. warning; following

C. Having warned; following

D. warned; followed

答案：

(答案→)A. Having been warned; following

B. warning; following

C. Having warned; following

D. warned; followed

解析：考查非谓语动词的用法，第一空填现在分词的完成式做状语，因为warn和逻辑主语young women是被动关系，而且是先被警告有危险，然后才在朋友或家人的陪伴下回家的，第二空填following做宾语补足语，因为following和修饰的宾语a friend or a family member是主动关系，句意是：被警告晚上街上很危险，年轻的女士只好在朋友和家人的跟随下回家，选A。
