                                                                                    茅屋为秋风所破歌

                                                                                           杜甫

八月秋高风怒号，卷我屋上三重茅，茅飞渡江洒江郊，高者挂罥长林梢，下者飘转沉塘坳。南村群童欺我老无力，忍能对面为盗贼。公然抱茅入竹去，唇焦口燥呼不得，归来倚杖自叹息。俄顷风定云墨色，秋天漠漠向昏黑。布衾多年冷似铁，娇儿恶卧踏里裂。床头屋漏无干处，雨脚如麻未断绝。自经丧乱少睡眠，长夜沾湿何由彻！安得广厦千万间，大庇天下寒士俱欢颜，风雨不动安如山。呜呼！何时眼前突兀见此屋，吾庐独破受冻死亦足！
