阅读下面这首古诗，完成(1)(2)两小题
                                                                                                          山寺夜起
                                                                                                             江湜
                                                                                             月升岩石巅，下照一溪烟。
                                                                                             烟色如云白，流来野寺前。
                                                                                             开门惜夜景，矫首看霜天。
                                                                                             谁见无家客，山中独不眠。
