阅读下面这首古诗，回答后面的题。
                                                                                                     雨后池上
                                                                                                        刘攽
                                                                                   一雨池塘水面平，淡磨明镜照檐楹。
                                                                                   东风忽起垂杨舞，更作荷心万点声。
