                                                                                                                                唐  白居易

                                                                                                            孤山寺北贾亭西，水面初平云脚低。

                                                                                                           几处早莺争暖树，谁家新燕啄春泥。

                                                                                                           乱花渐欲迷人眼，浅草才能没马蹄。
