阅读下面一首诗，完成小题。
                                                                                                         春 望
                                                                                                          杜甫
                                                                 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。
