[赏析] 韩愈，字退之，倡导了"唐代古文"运动,被尊为“唐宋八大家〞之首。这是一首描写和赞美早春美景的七言绝句。
4、钱塘湖春行 〔唐〕白居易
孤山寺北贾亭西，水面初平云脚低。几处早莺争暖树，谁家新燕啄春泥。
乱花渐欲迷人眼，浅草才能没马蹄。 最爱湖东行缺乏，绿杨阴里白沙堤。
水面初平：春天湖水初涨，水面刚刚平了湖岸。初：副词，刚刚。云脚低；指云层低垂，看上去同湖面连成一片。 早莺：初春时早来的黄鹂。莺：黄鹂，鸣声婉转动听。 争暖树：争着飞到向阳的树枝上去。 新燕：刚从南方飞回来的燕子。 行缺乏：百游不厌。 阴：同“荫〞，指树阴。白沙堤：即今白堤，又称沙堤、断桥堤，在西湖东畔，唐朝以前已有。白居易在任杭州刺史时所筑白堤在钱塘门外，是另一条。
