阅读下面这首古诗，回答两题。
                                                                                                           宿山寺
                                                                                             众岫耸寒色，精庐向此分。
                                                                                             流星透疏水，走月逆行云。
                                                                                             绝顶人来少，高松鹤不群。
                                                                                             一僧年八十，世事未曾闻。
