大家好!我是一位小導游。今天，我就給出大家介紹一下著名的世界遺產――長城。__曾經(jīng)說過：'不到長城非好漢。'今天，你們要登長城做好漢了!祝賀你們!你們知道嗎?長城被列入'世界'遺產的時間是20__年12月。長城是中國的像征，身為中華兒女的我們，又怎么能不驕傲呢?

大家記得古時候有一個傳說嗎?那是勤勞的孟姜女為了找被官兵捉去建筑長城的丈夫，經(jīng)過許多艱難困苦，來到長城邊。當她四處打聽，才知道丈夫被活活地累死了，于是，她在長城哭了三天三夜。突然，只聽'轟隆'一聲，長城被哭倒了800里。游客們，這是多么感人的故事啊，可見，萬里長城凝結了千萬人民的血汗，是中華人民智慧的結晶。

長城總長約6700千米，最有名的八達嶺長城隨山勢起伏，南北兩邊都有高峰聳立著。大家請跟我來。看，長城主要由關隘、城墻和烽火臺三部分組成的。城墻是長城的主要工程，特別堅固，是用巨磚、石條等材料砌成的。關隘就是長城沿線的重要駐兵據(jù)點。大家請看看旁邊，城頂上有一個垛口，每個垛口上都有一個小口，那就是嘹望口。垛口下面都有一個槍擊口。至于烽火臺，是有軍情時點燃烽火來傳遞信息的建筑?，F(xiàn)在，大家站在長城上遠眺，是不是前看不到頭，后見不著尾呢?

游客們，我先介紹到這里了，請大家漫步欣賞。大家注意了，在游覽時，不要亂丟垃圾，亂涂亂畫，愛護長城這一人們用血汗換來的世界遺產。
