    陶渊明生于东晋末朝,出身于没落的地主官僚家庭。他少时颇有壮志,博学能文,任性不羁。当时社会动乱不安,他有志不得展。做过小官,由于不满官场的丑恶,弃官回乡,这时他四十一岁,从此过着“躬耕自资”的隐居生活。忧愤、饥寒、劳累、赢疾一起折磨着他,六十三岁去世。后称靖节先生。他所作的诗文,内容多描写农村生活,表现了优美的自然风光,抒发他热爱田园生活、乐于和农民来往和不愿与统治者同流合污的高尚感情;但也包含了乐天知命、消极适世的因素。在形式上一反当时华而不实的文风,明朗清新,质朴自然,善于抓住客观事物最突出的特征,淡淡几笔传神的表现它的形象,简洁含蓄而富有韵味,对后代作家有较大的影响。本文写作年代大约是宋永初二年(421年),其时陶渊明已经五十七岁了。他拒绝同刘格的来政权合作,不满黑暗的政治现实,同时由于他和农民接近,理解他们追求理想社会的愿望,所以写了这篇记和诗。
