阅读下面这首古诗，完成后面的题。
                                                                                                   如梦令
                                                                                   昨夜雨疏风骤，浓睡不消残酒。

                                                                                   试问卷帘人，却道“海棠依旧”。

                                                                                 “知否？知否？应是绿肥红瘦。”
