Having been lost in the mountains for a week ,the two students finally saved by the local police.
having been lost 还是lost 对，为什么？

Having been lost是对的，表示一种状态，他们是在“在山中迷路了一个星期的”状态下被当地警察救了。

having been lost 对，因为有时间状语for a week ，所以有较明显的时间先后顺序.

having been lost
因为后面有for a week做前提就用完成时啊

对滴...

having been lost
明显有时间的先后顺序嘛（for a week),用完成时比较好

时间短语for a week作状语，有时间的先后顺序，前面用完成时最适合了。
