诗歌鉴赏

                                                                                                                春望
                                                                                                 国破山河在，城春草木深。
                                                                                                 感时花溅泪，恨别鸟惊心。
                                                                                                 烽火连三月，家书抵万金。
                                                                                                 白头搔更短，浑欲不胜簪。
