问题补充：

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

A. Warned; accompanied

B. Warning; accompanying

C. Having warned; accompanied

D. Having been warned; accompanying

答案：

A. Warned; accompanied

B. Warning; accompanying

C. Having warned; accompanied

(答案→)D. Having been warned; accompanying

解析：考查非谓语动词的用法。She与warn构成被动关系，所以使用过去分词或者having been done,第二空的friend与accompany构成主动关系，使用现在分词。句意：因为被警告晚上的街上有危险，所以她不得不让一个朋友陪她一起回家。选D。
