古人常化用前人诗文为己用,如曹操《短歌行》中的“                  ”就借用了《管仲·形解》中的“海不辞水,故能成其大;山不辞土,故能成其高”。王勃《滕王阁序》中的“                         ”出自北周庾信的《三月三日华林园马射赋》中的“落花与芝盖齐飞,杨柳共春旗一色”。王维《山居秋暝》中的“                          ”语出《楚辞》“王孙游兮不归,春草生兮萋萋”。李白《将进酒》“陈王昔时宴平乐,                  ”化用了曹植《名都篇》中的“归来宴平乐,美酒斗十千”。姜夔《扬州慢》中的“                         

                                      ”化用杜牧《寄扬州韩绰判官》诗句“二十四桥明月夜,玉人何处教吹箫”。吴激《人月圆》中的“恍然一梦,仙肌胜雪,宫鬓戴盆望天鸦。江州司马,青衫泪湿,同是天涯”化用了白居易《琵琶行》中的“                            ”,“                             ”。张先《剪牡丹·舟中闻双琵琶》“玉盘大小乱珠迸,酒上汝面,花艳眉相并”化用了白居易《琵琶行》中“                                       ”。王实甫《长亭送别》“                                               ,北雁南飞”化用了范仲淹《苏幕遮》中的“碧云天,黄叶地”。
