A.仕途失意
B.伤春惜别
C.羁旅行役之苦
D.怀古叹今之悲

【◆参考答案◆】:C

【◆答案解析◆】:《八声甘州》(对潇潇暮雨洒江天)一词写词人见秋景而生的思乡的愁绪,抒发了词人的羁旅行役之苦。上片采取层层铺叙的手法,描写登高所见秋景。开头两句总写,为整个画面奠定了“清秋”的基调。接下来五句为第二层,叙写清秋里的各种景色,霜风、关河、残照、树木花草,都带上了“清秋”的色彩。后两句集中在长江流水,把思绪引向远方,也暗含时间的流逝,漂泊日久;下片以委婉曲折的笔法,抒写思念故乡的情绪。下片可分为两个层次,前六句为一个层次,写自己对故乡的思念。诗人登高遥望远方的故乡,思归之情难以控制。【错误分析与防范】此题要求考生对这首词所表达的主要内容透彻理解。如果仅仅停留在词语含义的表层,就很容易误选其他3个选项。
