问题补充：

of the danger in the street at night, she had to go home, with a friend her.

A. Warned; followed

B. Warned; following

C. Having warned; followed

D. Having warned; following

答案：

A. Warned; followed

(答案→)B. Warned; following

C. Having warned; followed

D. Having warned; following

解析：本题考查非谓语动词。句子的主语she与warn之间是被动关系，且发生在句子谓语动词前，故应使用过去分词；后一个空格处是介词with的复合结构，friend与follow之间是主谓关系，应用现在分词。
