【题目】___________in the mountain for a week, the students were finally saved by the local police .
A. Having lost B. Lost C. Being lost D. Losing
在线课程【答案】B
【解析】
试题分析：B；考查分词作状语。词组be lost in是迷路的意思。在状语从句中，当从句主语与主句是一样的,主语和系动词可以省略，转换成状语从句应该是After they were lost in the mountains for a week.根据句意：这些学生困在山上一周后，最终被当地警察救了。故选B
