牛汉

                                                                                                                       远远的

                                                                                                                       远远的

                                                                                                                       一只棕红色的麂子

                                                                                                                       在望不到边的

                                                                                                                       金黄的麦海里

                                                                                                                       一蹿一蹿地似飞似飘

                                                                                                                       你为什么生得这么灵巧美丽

                                                                                                                       你为什么这么天真无邪

                                                                                                                       你为什么莽撞地离开高高的山林
