【甲】元丰六年十月十二日夜，解衣欲睡，月色入户，欣然起行。念无与为乐者，遂至承天寺寻张怀民。怀民亦未寝，相与步于中庭。

       庭下如积水空明，水中藻、荇交横，盖竹柏影也。

       何夜无月？何处无竹柏？但少闲人如吾两人耳。

                                                                                                                                                                   （选自苏轼《记承天寺夜游》）

      【乙】崇祯五年十二月，余住西湖。大雪三日，湖中人鸟声俱绝。

       是日更定矣，余拏一小舟，拥毳衣炉火，独往湖心亭看雪。雾凇沆砀，天与云、与山、与水，上下一白。湖上影子，惟长堤一痕，湖心亭一点，与余舟一芥，舟中人两三粒而已。

       到亭上，有两人铺毡对坐，一童子烧酒，炉正沸。见余大喜，曰：“湖中焉得更有此人！”拉余同饮。余强饮三大白而别，问其姓氏，是金陵人，客此。

       及下船，舟子喃喃曰：“莫说相公痴，更有痴似相公者。”
