导语：在长城介绍的撰写旅程中，学习并吸收他人佳作的精髓是一条宝贵的路径，好期刊汇集了九篇优秀范文，愿这些内容能够启发您的创作灵感，引领您探索更多的创作可能。
1、长城（The Great Wall），又称万里长城，是中国古代的军事防御工事，是一道高大、坚固而且连绵不断的长垣，用以限隔敌骑的行动。长城不是一道单纯孤立的城墙，而是以城墙为主体，同大量的城、障、亭、标相结合的防御体系。
2、长城修筑的历史可上溯到西周时期，发生在首都镐京（今陕西西安）的著名的典故“烽火戏诸侯”就源于此。春秋战国时期列国争霸，互相防守，长城修筑进入第一个，但此时修筑的长度都比较短。秦灭六国统一天下后，秦始皇连接和修缮战国长城，始有万里长城之称。明朝是最后一个大修长城的朝代，今天人们所看到的长城多是此时修筑。
3、长城资源主要分布在河北、北京、天津、山西、陕西、甘肃、内蒙古、黑龙江、吉林、辽宁、山东、河南、青海、宁夏、新疆等15个省区市。其中河北省境内长度2000多千米，陕西省境内长度1838千米。根据文物和测绘部门的全国性长城资源调查结果，明长城总长度为8851.8千米，秦汉及早期长城超过1万千米，总长超过2.1万千米。
4、1961年3月4日，长城被国务院公布为第一批全国重点文物保护单。1987年12月，长城被列入世界文化遗产。

Everybody is good! Welcome to badaling scenic area tourism.
The Great Wall is one of the seven wonders of the world. It is the blood of the working people in ancient China, is also a symbol of ancient Chinese culture and the pride of the Chinese nation. Visitors, we have come to the famous badaling Great Wall, on both sides of the mountain, is the pine and cypress, like hidden-away east, birds sounds, gurgling streams, is full of poetic. To the distance, you can see the Great Wall is divided into south and north two peak, winding in the mountain ridges, long teng hu yue, spectacular, the scenery is very spectacular. The Great Wall built around the mountain, ups and downs, twists and turns. This period of the Great Wall of the wall is made of neat huge stone is some stone for up to 2 meters, weighing hundreds of pounds. Internal fill soil and stones, to the top of the wall where the ground covered square brick, very smooth. The wall of the lateral horse-refraining pits of building has 2 meters high, and have made a in, next shot mouth, for look and shooting. Every city wall, built a fortress of square ChengTai type. ChengTai have high low and high called the enemy, is the watchman sergeant and accommodation; Low called Taiwan, height and the wall was similar but prominent wall, have the crenel around, is where the patrol.
Badaling at an altitude of 1000 meters, the twists and turns of the Great Wall, such as the dragon take off on the mountains. It is not only a hardworking, the crystallization of the wisdom of the Chinese nation, is also an excellent representative of ancient architecture engineering. The badaling Great Wall, the distant, rolling hills, XiongChen, stiffness of the north to the mountain. Due to the Great Wall and grand Great Wall for to the mountain, to the mountain is more dangerous.
Here are the beacon tower, also known as beacons, Wolf yantai. Independent buildings is not connected to the Great Wall. Once the enemy pounce, communicate its kindle wars and light smoke during the day is called "ran, called flint fire at night. When the Ming dynasty, also on the relationship between the war with the enemy made a strict rules: the enemy hundreds, burning a smoke point a gun; Five hundred people, burning two smoke point two guns; More than one thousand people, three smoke SAN pao; More than five thousand people, four smoke four guns; More than ten thousand people, five five gun smoke. In this way, on the border of the military intelligence can rapid transfer to the imperial city ouchi. See the beacon tower, and then tell you a story, called "must play leud" : the zhou dynasty had a king named weeks you king, he has a beautiful woman, her temper is very strange, always don't smile, think of some way to you king. He lit up a distress signal (fire), as a result, drew leud come white, she laughed, you king is also very happy. But, really have an enemy to attack, you king lit the fire, but no one come, and he was killed by the enemy. There is a story, called "meng jiangnu cry Great Wall collapse" : legend was Meng Gusheng a daughter named meng jiangnu. Because of qin shi huang to build the Great Wall, need a lot of manpower. Qin shi huang was caught many people go to the Great Wall.
All of a sudden, I do not know where to come up to a rumor: only the wan xi is buried under the Great Wall, can make the Great Wall and solid, qin shi huang was, sent people seize wan xi. Wan xi good fled to Bangladesh. People see wan xi meng home good handsome, talented, good let meng jiangnu and wan xi of their marriage. The two men marry less than 10 days, good wan xi is the rulers who grasp to go to repair the Great Wall. In the fall, meng jiangnu saw her husband hasn't come back, give him the woolies. Along the way, reject, hardships, day and night, all the way to the Great Wall. Local people told her: wan xi good would have buried under the wall. She was grief-stricken, crying. Instantly, and dark, the Great Wall was crying collapsed in eight hundred. Just then, qin shi huang to have the Great Wall, with fine features, when he saw meng jiangnu just want her to do concubine. For qin shi huang meng jiangnu agree to her three conditions: one is for wan xi is a grave; The second is to make good full chao wenwu festivals wan xi; Three is in the middle of the Great Wall and the tomb of wan xi good repair a like flying grand bridge. After three things done, she threw herself into the sea.
Visitors, this is three stories about the Great Wall. Now the Great Wall tourist stop here, thank you!

Good morning! My name is Chen Ying snow, carefree travel guide, today is a great pleasure to serve you, you can call me snow! Today we are going to visit the Great Wall of landscape is famous in the world. The Great Wall is the world's precious historical relics, hope everyone to love the Great Wall, don't litter scribble, oh!
The Great Wall has a long history, a history of more than 2000 years, the spring and autumn period and the warring states period, the warring states to mutual defense, has built the Great Wall in the dangerous place. According to records zuozhuan: in 656 BC, "chu mahjong layout" is about the earliest record of the Great Wall. Out the six nations after the unification of China, qin to defense the north south invasion of the huns, in 224 BC, the qin, zhao and yan in The Three Kingdoms of the north Great Wall, re-hung, coherent rise. Some west about (now min county, gansu province) north mountain, east to liaodong, which is commonly known as the "Great Wall", still remains. Since then, the han, the northern wei dynasty, their, beiqi, sui dynasties had built the Great Wall. The composition
In Ming dynasty, in order to defense the invasion of alien, built the Great Wall before and after 18 times, total length of 6700 km, east of shanhaiguan, west to jiayuguan, today we visit this section of the Great Wall is built in the Ming dynasty, is located in the badaling.
Now we have arrived at the foot of badaling. Tourists friends, please look up at the Great Wall: it is like a huge dragon, winding between mountains. Please follow me to the Great Wall, see: every three hundred meters on the walls of the Great Wall there is a square ChengTai, is an ancient fortress to station troops. It is said that war, between the ChengTai can mutual echo. On the top of the walls are covered with very flat square brick, like a wide road, probably ErSanTai car can be parallel. Outside the wall along with many more than two meters high, the rows of the crenel, for? With hope and shot. The composition
My friends, have a look at your feet? Guess what weigh? Tell you! This is a stone, a piece of have two or three one thousand catties! At that time, there is no train, automobile, also have no crane, is by the shoulder of countless countless hands, step by step, carry on the steep mountains. This is how many working people sweat and wisdom, to condense into the former does not see the head, after see the tail of the Great Wall!
This is the Great Wall! This is the west jiayuguan, east to shanhaiguan, which meet the sea sunrise and gobi desert sun, or turned on the peaks, or bent over in the valley, the ups and downs, stretching thousands of miles of the Great Wall. It is such a magnificent verve, Great Wall is a great miracle in the history of the world!
Dear visitors, today's visit here will be over, thank you very much for my support and cooperation. The majestic Great Wall forever awaits respectfully you the presence!

Everybody is good! Welcome to badaling scenic area tourism. Accompany you visit together, today I am very happy, hope all can spend a good time in badaling.
Right now, I would go to visit the door
Badaling Great Wall, and now, I'll about matters needing attention: the Great Wall is one of the famous wonders of the world, it is like a dragon entrenched in north China's vast land. It is the crystallization of labor people's blood law in ancient China, is also a symbol of ancient Chinese culture and the pride of the Chinese nation, please don't scribble on the brick fluidized.
Visitors, now we have come to the famous badaling Great Wall, to the distance, you can see the Great Wall is divided into south and north two peak, winding in the mountain ridges, long teng hu yue, spectacular, the scenery is very spectacular. Look here is a two openings and u-shaped walls satin afraid brought to the barbican. Both inside and outside the barbican wall on both sides have the crenel wall, all defensive ring. If the enemy breached close into the city, will have been all around guarding city will panic in the enemy like fall in the urn. The barbican is an important part of the Great Wall. It is generally built on terrain dangerous traffic arteries. Badaling the barbican is no exception. Built on the ridge, restricted by terrain, mountain potential, low west high east, east narrow width, only 5000 square meters. There is no hole in the barbican, lack of water, usually few troops, guarding city forces in the northwest three mile fork city. Barbican in a "examine the courtyard mansion", the original is stay accommodation for the emperor passed in or officials. Barbican 63.9 meters apart, between the two door XiMenMei TiE "north gate lock-and-key", it meant I have spoken in front.
City on the doorway, ancient into install a huge double wooden door, door installation has wooden needle and latches. At ordinary times, both doors open and the pedestrian travel free access; Wartime gate closed, sealed hard; Once struck back order, city door is the export of hammering dashed forward. Barbican east gate lintel TiE as "the agent to fill", built during Ming jiajing eighteen years. Town "outside" the commonplace GuanCheng city on the stage, the original is embedded with a piece of stone, is the Ming wanli years of print. From the inscriptions could look around the Great Wall, has the more than 80 years time to complete. This tablet is a record of construction time, length of the Great Wall and the officer and tube foreman, burning head, head of the potter, mason head and name, in order to make clear the responsibility. Stand to look down on the city, we see in constant traffic and visitors through the door. Here is not only an important military defense of the ancient barrier, but also traffic arteries. From here, nantong changping, Beijing, north to yanqing, northwest to xuanhua, zhangjiakou, "convenient way from now on,". Badaling is hence the name.
When we came to linhai Great Wall, at the foot of the Great Wall, look up, the endless winding high steps, as if is a path to a blue sky of the ladder, and he seems like a dragon hou lie in rolling peaks.
Along the stairs up, came to the first gate "range gate", the ancient scene immediately appear at present, the gate is a two layers of ancient buildings, two sides of the ancients of flags fluttering, increased the antique appeal. The second floor is "clearly" lake mountain, standing there, "the east lake park" as a painting, panoramic view, I'd like to bring a "lake mountain" may be just that.
The walk, we came to the second gate "Gu Jing floor", standing on the roof of almost half of linhai city is clearly visible. Go up again, we finally boarded the highest floor of the Great Wall "Bai Yunlou", "finally finished!" I shouted happily. Standing on the "Bai Yunlou", panoramic view of the city, you see the white tower is the tallest building in linhai city, the distance of the "white band" is the yongning river to the sea.
2、然后就是叫物料员去仓库领用物料，俗称备料。
3、准备好物料以后，接着准备相应的工作夹具，作业指导书，如果是第一次生产的话，还要通知相关技术人员到现场指导。
4、物料都就绪以后，然后就安排生产人员进行生产。
5、将成品生产出来以后，再然后就是OQC品管进行质量检查，检查没有问题以后进行包装。
关键词：MB+网 工业以太网 1.现状分析
新钢公司为适应全局的发展，在烧结厂现有115m2烧结机的生产场地上合理布局，再造了一台180m2的烧结机，两台烧结机由于工艺布局上的原因共用了一条上料系统，即115m2烧结机的配料系统。新建的180m2烧结机通讯网络上采用的是基于TCP/IP的工业以太网，其传输介质是光纤，数据传输速率高，而于始建于2000年的115m2烧结机及其配料系统在通讯网络上采用的是MODIBUS PLUS（简称MB＋）网，其传输介质为两芯屏蔽双绞线，数据传输速率相对较低，而现在工艺布局上要求两台烧结机必须共用一个上料系统，它们之间必然在存在通讯上的连接。115m2烧结机的通讯网络采用的是单网架构，其通讯的稳定性和安全性紧密依赖于单条通讯电缆，在通讯安全上存在不足。当然两台烧结机在以下方面存在共性，115m2烧结机采用的PLC控制模块是MODICON公司的，180m2烧结机也是；两台烧结机的上位编程软件和监控软件均为CONCEPT和IFIX，只是版本不同。基于上述情况，我们考虑将115m2烧结机的单网架构的MB＋网改造成双网架构的以太网，从180m2烧结机主控室到配料系统主控室，配料系统主控室到115m2烧结机主控室均运用双光缆进行通讯。
2.改造思路
通过上述分析，我们对整个改造工程有了一个比较清晰的思路。实现通讯的关键在于通讯模块的选用,我们通过对施耐德电气提供的TCP/IP网络设备进行了分析比较，最终决定选用其型号为140 NOE 711 X0(100 Base Tx/Fx)的以太网通讯模块用来作通讯连接。NOE 771 X0模块具有以下优点，它提供RJ-45双绞线接口及MT-RJ光纤接口各一个，使用以太网的通讯方式，支持Peer Cop 定义 I/O 数据表，支持JAVA及嵌入式WEB服务用来管理PLC硬件。它的连接方式也非常简单，只需在现有PLC机柜底板空闲槽位上插入NOE模块即可，且支持热拔插。在确定了通讯模块的选型后，我们的思路有以下几条。
1、首先铺设光缆，从115m2烧结机主控室到配料主控室，再从配料主控室到180m2烧结机主控室铺设双光缆。
2、请专业人员对光缆头与光收发器进行融接。用双绞线将光收发器与交换机相连，再用双绞线从交换机转接到NOE模块。
3、安装NOE模块和工控机上以太网卡，对各NOE模块和各相应工控机以太网卡的IP进行配置，接通其间的通讯。
4、对各工控机中上位机编程软件和监控软件配置进行更改，使其由MB＋连接方式转变为TCP/IP的连接方式。
5、对整个通讯网络进行测试验证，更改其中的错误，完善其中的功能。
完成改造后其网络结构示意图如下：
3.具体实施
首先我们对以下设备的选型作了明确，通讯模块我们选用了施耐德的NOE 77100，交换机我们选用了MOXA工业交换机。光缆我们选用了多模铠装光缆，光收发器为，网卡为D_LINK的，双绞线为AMP的超五类屏蔽线。
硬件的安装方面我们要注意光缆铺设时其变转角不得超过90。；融接光纤时要细心谨慎，光纤盒最好用卡带进行固定；在压制双绞线的水晶头时，要注意八根线的线序，压制完后，要测试其连通性；安装网卡时，注意网卡与计算机插槽的接触完好，由于我们要在每台计算机上安装双网卡，所以还要注意网卡中断资源的分配。
软件的配置方面重点在于IP地址的分配以及上位机编程和监控软件的配置。
我们先说一下IP地址的分配：比如我厂115m2烧结机主控室IP分配可以如下设置：
NOE1地址: 84.19.4.1，NOE2地址: 84.19.4.2
ZCFOS1操作站IP1地址：84.19.4.101，IP2地址：84.19.4.102
ZCFOS2操作站IP1地址：84.19.4.103，IP2地址：84.19.4.104
ZCFOS3操作站IP1地址：84.19.4.105，IP2地址：84.19.4.106

2结果
①参考组患者创面平均愈合时间为（28.34±6.13）d，观察组患者创面平均愈合时间为（19.68±5.28）d，数据比较有统计学意义（P<0.05）。
②参考组13例患者康复期间出现创面感染，感染发生率为34.2%，观察组3例患者康复期间出现创面感染，感染发生率为7.9%，差异有统计学意义（P<0.05)；治疗7d时，参考组患者致病细菌检出率明显高于观察组，差异有统计学意义（P<0.05),详见表1。
③观察组患者在治疗期间未出现局部或全身过敏症状，无创面疼痛，患者肝肾、血常规检查等均正常，参考组患者治疗期间未出现任何不良反应，数据比较无统计学意义（P>0.05）。
3讨论
纳米银敷料具有杀菌、抗菌效果，阴离子释放后，结合带负电荷的菌体蛋白质，并使其变形沉淀银同时与酶的巯基结合，从而形成稳定的硫酸盐[1]，抑制系列巯基的酶活性，将细菌呼吸酶系统阻断，对细菌代谢进行干扰，并最终导致细菌死亡，从而起到有效的抑菌及杀菌。银的杀菌机制与化学合成的抗菌剂不同，通过重金属离子对细菌蛋白质的变性产生作用，从而具有不易耐药、广谱杀菌的作用[2]。纳米银敷料化学特性稳定，能够与真菌及细菌的DNA结合，并促使其结构的改变，使真菌及细菌活性受到抑制[3]。重组牛碱性成纤维细胞生长因子作为生物活性较强的促分裂元，能够刺激成纤维细胞、上皮细胞、血管内皮细胞、真皮细胞等具有再生及促修复作用[4]。药物能够促进内皮细胞分裂，诱导其分泌某些蛋白酶，溶解并侵入周围基质，形成纤维细胞及毛细血管，建立侧支循环，促进新的毛细血管网的形成，血液流量、肉芽组织毛细血管数量等均明显增加，创面微循环有效改善[5]。重组牛碱性成纤维细胞生长因子等在创伤、烧伤及慢性溃疡的治疗中能够有效促进伤口愈合，能够促进供皮区、烧创伤、手术创面的良好愈合[6]。本次研究中，观察组患者创面平均愈合时间明显短于参考组（P<0.05），患者治疗中感染发生率明显低于参考组（P<0.05），治疗7d后观察组患者细菌检出率明显低于参考组（P<0.05），由此可见，纳米银敷料结合重组牛碱性成纤维细胞生长因子凝胶治疗烧伤残余创面；本次治疗中，两组患者均未出现不良反应，比较无统计学意义（P>0.05），由此可知，纳米银敷料及重组牛碱性成纤维细胞生长因子凝胶在创面治疗中均不会产生严重不良反应，安全性高，值得推广使用。

想要成为一位合格的小导游，一份精彩、生动的导游词必不可少。导游词中，既要有对景区的整体介绍，也要有对某个景点的重点讲解，如果还能对景点名称的由来侃侃而谈，并且巧妙地穿插景观背后的历史和故事，引用名人留下的诗句或对联，就更能激发游客的兴趣了。快跟上我的脚步，打造一份独特的导游词，让更多的游客进一步领略世界文化遗产的艺术魅力，留下美好的回忆吧！
当我们与游客初次见面时，首先应向游客问好，然后进行自我介绍，再说欢迎词，最后告知将会带大家去哪一处景点，说明游览的目的，最重要的是别忘了带上你的热情与礼貌哟！请注意，本次列车即将到达旅程的第一站――八达岭长城。
“各位游客大家好，欢迎大家搭乘我们的游览专列，我是你们的导游。首先，我要祝贺大家即将成为真正的‘好汉’！因为我们今天将登上八达岭长城，真正感受‘不到长城非好汉’的意境。”
在游客们准备下车，开始今天的游览行程之前，小导游不妨先总体介绍这处景点的基本情况，比如它的地理位置在哪儿，它在全国甚至全世界有什么地位，等等。
“现在，我们的列车马上就要进入八达岭景区了。大家看，前面的那座就是军都山，长城就像一条巨龙盘踞在这座山上。长城是中华文化的瑰宝，是世界文化遗产之一，被誉为世界建筑的奇迹！它东起山海关，西至嘉峪关，是中国古代人民智慧血汗的结晶，也是中国古代文化的象征和中华民族的骄傲。我们今天要参观的八达岭长城是明代修筑的，它气势磅礴，正是万里长城的精华。”
当游客步入景区时，导游的核心任务就是向他们展示这一景区的最大魅力与特色，并重点介绍几处著名的风光或景观。简单来说，我们可以按照游览顺序，对所选景观逐一进行生动的、具体的描述和解说，使游客尽情览景点风光。
“朋友们，我们现在已经来到了长城脚下，请大家先朝远处看。长城像不像一条在崇山峻岭上伏卧的巨龙？它时隐时现，正准备腾空翱翔呢！长城高大坚固，它是由巨大的条石和城砖筑成的，是我国古代重要的军事防御工程。
让我们登上长城看看吧。这里的城砖十分平坦，道路十分宽阔，要是在古代，五六匹马可以并排行走。请大家再走近些看看，这里的城墙外沿还有两米多高的成排的垛子，大家能猜到垛子上方形的口子有什么功用吗？大家猜对了！这些方形的口子又称为t望口或射口，供古时戍守的将士们t望侦察和射击防御。我们再稍稍抬头，可以看到城墙顶上每隔三百多米就有一座方形的城台，那是屯兵的堡垒。打仗的时候，城台之间还可以相互呼应呢。”
成功的导游词不需要“眉毛胡子一把抓”，但要使内容更丰富、语言更生动，快向我学习这几个小妙招：首先，恰当地使用比喻、拟人、夸张、象征等手法，使静止的景观化为生动鲜活的画面，让游客沉浸和陶醉其中；其次，运用列数字的方法描述景观的特点，让游客真正游有所得、有所收获；再次，可以不失时机地穿插趣味盎然的神话传说、民间故事、诗文典故，引发游客的好奇心理，给他们留下深刻的印象。
“八达岭长城的墙体平均高7.8米，墙底宽6.5米至7.5米，顶宽4.5米。往下看是由两个门洞和U字形墙组成的瓮城。由于长城是一个完整的军事防御体系，因此它不仅有瓮城和城墙，还有传报军情的烽火台。
大家知道吗？长城是有感情的呢。关于长城有一个传说，相传秦始皇时劳役繁重，青年男女范杞梁、孟姜女新婚不到三天，新郎就被抓去修长城了。孟姜女在家等了很久也不见丈夫归来，就万里寻夫来到长城脚下。不料丈夫已经变成一堆白骨，孟姜女悲恸不已，在此大哭了三天三夜，哭倒了长城，自己也变成了一块望夫石。”
当我们旅游专列第一站的游览接近尾声时，小导游们可千万别忘了有礼貌地向游客道别，顺便也给今天的游览行程做一个小结。
一下车，就看到了一块大石碑，上面写着“八达岭长城”五个亮晶晶的大字。再往前看，一条长龙卧在那蜿蜒的山峰上，一眼望不到边。早在车上，导游就介绍过了，八达岭长城史称天下九塞之一，是万里长城的精华，在明长城中独具代表性。既然是九塞之一，当然是十分陡峭。所以年老体弱的可以先坐滑车到第四个烽火台，再登三个烽火台到山顶，如果要当好汉的那就要从山脚第一个烽火台一直往上登到第七个烽火台到山顶。听了导游的介绍后，我就跃跃欲试，当然我是要做好汉的了。
我刚站在八达岭城的入城口，我的腿就不禁抖起来，那看起来耸入云霄的烽火台与笔挺的台阶着实让我不寒而栗。我心里不禁有点后悔了，那么陡，怎么爬得上去啊！做滑车多省心啊！可是这世界上是没有后悔药的。既然已经来到了长城脚底下了，那就登上山顶征服长城吧！也不枉我来此一趟了。我战胜了心中的胆怯大步往上攀登。
刚开始台阶虽有些陡，但还能爬得上去，可过来一会儿，就越来越陡了，只好借助于长城两端建好的栏杆，扶着那长长地栏杆一步一步往上爬，慢慢地我终于登上了第一个烽火台，脚就像罐了铅一样，很酸！我站在烽火台上极目远眺心旷神怡，山下都是郁郁葱葱的树林，风迎面吹来，把我一身汗水吹得无影无踪。我的力气又回来了，继续吧！爬过一道道斜坡和高高的台阶，爬一会儿休息一会儿，不管认识的，还是不认识的，老的少的，经过身边的时候都不忘相互提醒喊声“加油”。经过漫长的上下斜坡路和近乎垂直地台阶。我和妈妈都没了力气，那长长的台阶似乎得意地在对我说：“哈哈，没力气了吧，登不上去了吧，就别当好汉了，回去吧！”我的心中似乎一下子又充满了力量，用手甩去额头的汗珠，手攀着那漫长而又结实的栏杆，脚踏着坚定的步伐，心中充满了登上长城的信念。
那天天气非常好,一大早我们就坐车去八达岭长城了。大概过了一个小时,透过车窗,我看见远处出现了连绵不断的高山,山峰上隐隐约约出现了白色的城墙,城墙在红彤彤的朝霞的映衬下,犹如一条歪歪扭扭的金丝带,爸爸告诉我那就是闻名中外的长城。旅游车离长城越来越近,我的心也越来越激动,感觉时间过得真慢!几分钟后,我们的车就来到了离长城脚下不远处的车站,我迫不及待地下了车。
首先映入我眼帘的是镌刻在路边巨石上的名言：不到长城非好汉。我们在巨石前拍照留影,爸爸兴奋地对我说：“我们今天一定要做回好汉!”买好门票,我们就进入景区了。我站在长城的入口处,向远方眺望,只见长城蜿蜒曲折、连绵不断,远处的游人似一个个小点,缓缓地上下移动。我们一边登长城,爸爸一边向我介绍长城的知识。爸爸告诉我,八达岭长城是1505年的明朝开始兴建的,主要是为了抵御外敌的入侵,城墙两边锯齿形的叫垛口,上面有?望口,下面有射击口,高高的像楼房似的建筑叫烽火台,当士兵发现有敌人入侵时,就点燃烽火台上预先准备好的柴火,远处的士兵看见烽火台上冒出的黑烟,便知道有敌情,会迅速赶来增援。听了爸爸的介绍,我想：我国古代的人民真聪明啊!
不知不觉中,我们就登上了一个烽火台,我向北面望去,只见城墙脚下山石起伏,我的眼前仿佛浮现了当年战争的残酷场面：千军万马滚滚而来,城墙上战鼓喧天,入侵的敌人有的手提大刀,有的手持长枪,还有的肩扛炸药……长城上的士兵奋勇抵抗,到处是厮杀声,到处是呐喊声,到处是鲜血和尸体……我再看长城的南面,一块巨大的广告牌展现在我的眼前,上面用中英文写着：同一个世界,同一个梦想。我想这既是2008年北京奥运会的宣传语,也是我们今天生活的真实写照,我们生活在和平年代,要更加珍惜来之不易的美好生活!
由于这天北风很大,我们走得很慢,有时是走两步退一步,所以我们不得不拉着扶手缓慢挪动身体,其他的游客也是走走停停,显得非常吃力,但是大家都没有停下来的意思,因为我们的共同目标都是长城的最高处－－海拔888米的“好汉坡”。
长城距今有2000多年的历史，总长50000多公里，是人类历史上占地面积最大的建筑。长城非常雄伟。它西起嘉峪关，东到三海关，全长有6700多公里，通称“万里长城”。城墙平均高7、8米，顶宽7、8米，可以5马并骑。万里长城全部都用大条石和城砖砌成的。如果把大条石和城砖连起来，就能绕地球一圈多。万里长城不但雄伟，而且美观。雄伟的巨龙穿行在丛林之中，城墙上面分布着成千上万座高大的烽火台，显得雄奇险峻充满巨大的艺术魅力。万里长城表现了劳动人民的智慧和才干，是我国宝贵的历史遗产。
名师点评：小作者给我们介绍了万里长城的有关知识，通过阅读小作者的文章，我们了解到了长城的历史、外貌及其在历史上的地位。文章语言描写生动形象，表达了小作者对长城的赞美之情。“东到三海关”改为“东到山海关”。
