                                                                                                      破阵子
                                                                                                        晏殊
                                                   燕子来时新社，梨花落后清明。池上碧苔三四点，叶底黄鹂一两声，日长飞絮轻。
                                                   巧笑东邻女伴，采桑径里逢迎。疑怪昨宵春梦好，元是今朝斗草赢，笑从双脸生。
