阅读下面这首诗，按要求完成题目
                                                                                     钱塘湖春行    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。
                                                                            最爱湖东行不足，绿杨阴里白沙堤。
