问题补充：

alone in a dark room, the little girl was so frightened as to cry loudly.

A. Leaving

B. Left

C. Being left

D. To be left

答案：

A. Leaving

(答案→)B. Left

C. Being left

D. To be left

解析：考查分词做状语。本句中的动词短语leave behind留下，遗留；与后面句子的主语the little girl之间存在着被动关系，故使用过去分词在句中做状语。句意：被独自一人留在黑屋子里，那个小女孩害怕地哭了起来。故B正确。
