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：考查非谓语动词用法。Warn与she之间构成被动关系，所以使用过去分词表示被动，排除BC。Warned和Having been warned都可以，第二空的friend与accompany构成主动关系，故使用现在分词的形式，故D正确。
