                                                                                              望  岳
                                                                                岱宗夫如何？齐鲁青未了。
                                                                                造化钟神秀，阴阳割昏晓。
                                                                                荡胸生层云，决眦入归鸟。
                                                                                会当凌绝顶，一览众山小。
