英语单项（需解释） --------in the mountains for a week ,we finally saved by local police
A ,Having lost B,Losing C ,Being lost D,Having been lost

D选项正解
lose 这个动词有表示跑丢了,迷路了的意思,用法是跑丢迷路者+ is lost.在这一句就是 We were lost（过去时嘛）
那么,这一句逗号后面已经主谓齐全了,是个完整的句子了,就是 we "were"（您应该是打漏掉了这个词）saved by local police 我们被当地警方救了.那么,前面一句的主语根据平行规则就是We 我们了.
我们怎么样呢?我们在山里面一周,难道是开Party吗?就是迷路了.
那么请问那么多个时态,用哪种呢?迷路这个动作,和获救这个动作.
迷路在先,获救在后,而且获救爽一下,迷路迷一周,迷路是个持续动作.
所以,be saved 用一般过去时.be lost 用 have been lost 完成时.
就变成 (After) we have been lost in the mountains for a week,we were finally saved by local police.有先后逻辑和持续状态的.
那么,要换一种更简单的说法,不需要用After呢,就要把逗号前面整句话变成一个修饰结构,就是把after we have done 变成 having been done.表示,主语先怎样怎样一段时间后,又怎样.
所以就是 Having been lost in .for a week,we were finally saved by local police.
翻译：在大山深处经历了一周的迷路之后,我们终于被当地警方救了!
再问：谢谢您详细的回答！我还有一个疑惑，为什么不能选A？
