诗词赏析。
                                                                                                             相见欢
                                                                                                         李煜【南唐】
                                                                           无言独上西楼，月如钩。寂寞梧桐深院锁清秋。
                                                                           剪不断，理还乱，是离愁。别是一般滋味在心头。
