问题补充：

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

A. Warned, followed

B. Warning, following

C. Having warned, following

D. Having been warned, following

答案：

A. Warned, followed

B. Warning, following

C. Having warned, following

(答案→)D. Having been warned, following

解析：考察非谓语动词，第一空和第二空都是作状语，第一空的warn与后面的逻辑主语之间是被动关系，所以排除BC,第二空的follow与他的逻辑主语 a friend 之间是主动关系，所以选择following，排除A，所以选择D

句意为，已经被警告晚上马路上很危险，她需要有一个朋友跟她一起回家。
