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。
