唐朝元和十二年(817)春末,白居易和16位朋友结伴游江西庐山,写了不少诗,其中有一首是《大林寺桃花》:“人间四月芳菲尽,山寺桃花始盛开。长恨春归无觅处,不知转入此中来!”
有一天,宋代著名的科学家、文学家沈括读了这首诗,非常惊讶,带着讥讽的口吻评论道:“既然‘四月芳菲尽’了,怎么会‘桃花始盛开’呢大诗人也写出这样自相矛盾的句子,可谓‘智者千虑,必有一失’呀!”说完,他也就把这事忘掉了。
想不到有一年 * * 的季节,他去游山,见到了白居易诗中的奇景:四月天气,山下众花凋谢,山顶上却是桃花红艳。猛然想起白居易的诗来,才领悟到自己错怪了大诗人,也从中发现了高度对季节的影响:由于山上气温低,春季到来晚于山下。
后来,他又找来白居易的诗再读,发现前面有一篇序,序中写道:“(大林寺)山高地深;时节绝晚,于时孟夏月(即四月),如正二月天;梨花始华(花),涧草犹短。人物风候,与平地聚落不同。”沈括读了,很有感慨地说:“都怪我读书不细,经验太少啊!”
请回答:
(1) 运用辩证法有关知识说明沈括为什么会错评了白居易的诗。
(2) 白居易与沈括一前一后取得了“高度对季节的影响”的认识,这说明了什么
