                                                                                       【甲】 次北固山下                                     乙】落叶
                                                                                                 王湾                                                    唐 孔绍安
                                                                               客路青山外，行舟绿水前。                    早秋惊落叶，飘零似客心。
                                                                               潮平两岸阔，风正一帆悬。                    翻飞未肯下，犹言惜故林。
                                                                               海日生残夜，江春入旧年。
                                                                               乡书何处达，归雁洛阳边。
