问题补充：
of danger in the street at night by police, young women in India nowadays have to go home with a friend or a family member them.
A. Having been warned; following
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：句意：警察告知了印度的妇女晚上在街上走是危险的，她们现在回家时有朋友或家人陪着。这里逗号后是一个句子，整个句子没有连词，所以第一空应该用非谓语动词，young women与warn之间是被动关系，故排除CD；因为这些妇女先是被警告有危险，然后晚上回家时有家人或朋友陪着，所以先发生warn又发生的谓语动词，故用分词的完成时；第二空是with的复合结构，a friend or a family member与follow之间是主动关系，故用现在分词表主动，故选A。
