问题补充：

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

A. Warned; accompanied

B. Having warned; accompanying

C. Warning; accompanying

D. Having been warned; accompanying

答案：

A. Warned; accompanied

B. Having warned; accompanying

C. Warning; accompanying

(答案→)D. Having been warned; accompanying

解析：句意：她被警告在晚上的街上有危险，她不得不让一个朋友陪着回家。整个句子没有连词，句子已经有谓语动词，所以第一空是非谓语动词，warn与she之间是被动关系，故用过去分词，这里warn的动作发生在had to go home之前，所以用having been warned；第二空是with的复合结构，friend与accompany之间是主动关系，故用现在分词，故选D。
