悯农二首·其二 李绅 〔唐代〕 锄禾日当午，汗滴禾下土。 谁知盘中餐，粒粒皆辛苦？ 悯农译文及注释 译文 盛夏中午，烈日炎炎，农民还在劳作，汗珠滴入泥土。 有谁想到，我们碗中的米饭，一粒一粒都是农民辛苦劳动得来的呀？ 注释 禾：谷类植物的统称。 餐：一作“飧”。熟食的通称。 悯农创作背景 根据唐代范摅《云溪友议》和《旧唐书·吕渭传》等书的记载，大致可推定这组诗为李绅于唐德宗贞元十五年（公元799年）所作。 悯农赏析 首诗描绘了在烈日当空的正午农民田里劳作的景象，概括地表现了农民终年辛勤劳动的生活，最后以“谁知盘中餐，粒粒皆辛苦”这样近似蕴意深远的格言，表达了诗人对农民真挚的同情之心。 一开头就描绘在烈日当空的正午，农民依然在田里劳作，那一滴滴的汗珠，洒在灼热的土地上。这就补叙出由“一粒粟”到“万颗子”，到“四海无闲田”，乃是千千万万个农民用血汗浇灌起来的；这也为下面“粒粒皆辛苦”撷取了最富有典型意义的形象，可谓一以当十。它概括地表现了农民不避严寒酷暑、雨雪风霜，终年辛勤劳动的生活。 “谁知盘中餐，粒粒皆辛苦”，不是空洞的说教，不是无病的呻吟；它近似蕴意深远的格言，但又不仅以它的说服力取胜，而且还由于在这一深沉的慨叹之中，凝聚了诗人无限的愤懑和真挚的同情。 诗人在阐明上述的内容时，不是空洞抽象地叙说和议论，而是采用鲜明的形象和深刻的对比来揭露问题和说明道理，这就使人很容易接受和理解。 作者在前两句并没有说农民种田怎样辛苦，庄稼的长成如何不易，只是把农民在烈日之下锄禾而汗流不止的情节作了一番形象的渲染，就使人把这种辛苦和不易品味得更加具体、深刻且真实。所以诗人最后用反问语气道出“谁知盘中餐，粒粒皆辛苦”的道理就很有说服力。尤其是把粒粒粮食比作滴滴汗水，真是体微察细，形象而贴切。
