       【甲】风烟俱净，天山共色。从流飘荡，任意东西。自富阳至桐庐，一百许里，奇山异水，天下独绝。水皆缥碧，千丈见底。游鱼细石，直视无碍。急湍甚箭，猛浪若奔。夹岸高山，皆生寒树，负势竞上，互相轩邈；争高直指，千百成峰。泉水激石，泠泠作响；好鸟相鸣，嘤嘤成韵。蝉则千转不穷，猿则百叫无绝。鸢飞戾天者，望峰息心；经纶世务者，窥欲忘反。横柯上蔽，在昼犹昏；疏条交映，有时见日。
       【乙】至于负者歌于途，行者休于树，前者呼，后者应，伛偻提携，往来而不绝者，滁人游也。临溪而渔，溪深而鱼肥；酿泉为酒，泉香而酒冽；山肴野蔌，杂然而前陈者，太守宴也。宴酣之乐，非丝非竹，射者中，弈者胜，觥筹交错，起坐而喧哗者，众宾欢也。苍颜白发，颓然乎其间者，太守醉也。
