                                                                                         赋得古原草送别
                                                                                            唐 白居易
                                                                                 离离原上草，一岁一枯荣。
                                                                                 野火烧不尽，春风吹又生。
                                                                                 远芳侵古道，晴翠接荒城。
                                                                                 又送王孙去，萋萋满别情。
