In the north of China,there lies a 6,700-kilometer-long (4,161-mile-long) ancient wall.Now well-known as the Great Wall of China,it starts at the Jiayuguan Pass of Gansu Province in the west and ends at the Shanhaiguan Pass of Hebei Province in the east.As one of the Eight Wonders in the world,the Great Wall of China has become the symbol of the Chinese nation and its culture.
  Lots of beautiful legends and stories about the Great Wall took place following along the construction,and since that time these stories have spread around the country.Those that happened during construction are abundant,such as Meng Jiangnu's story and the legend of the Jiayuguan Pass.Meng Jiangnu's story is the most famous and widely spread of all the legends about the Great Wall.The story happened during the Qin Dynasty (221BC-206BC).It tells of how Meng Jiangnu's bitter weeping made a section of the Great Wall collapse.Meng Jiangnu's husband Fan Qiliang was caught by federal officials and sent to build the Great Wall.Meng Jiangnu heard nothing from him after his departure,so she set out to look for him.Unfortunately,by the time she reached the great wall,she discovered that her husband had already died.Hearing the bad news,she cried her heart out.Her howl caused the collapse of a part of the Great Wall.This story indicates that the Great Wall is the production of tens of thousands of Chinese commoners.
Another legend about the Jiayuguan Pass tells of a workman named Yi Kaizhan in the Ming Dynasty (1368BC-1644BC) who was proficient in arithmetic.He calculated that it would need 99,999 bricks to build the Jiayuguan Pass.The supervisor did not believe him and said if they miscalculated by even one brick,then all the workmen would be punished to do hard work for three years.After the completion of the project,one brick was left behind the Xiwong city gate.The supervisor was happy at the sight of the brick and ready to punish them.However Yi Kaizhan said with deliberation that the brick was put there by a supernatural being to fix the wall.A tiny move would cause the collapse of the wall.Therefore the brick was kept there and never moved.It can still be found there today on the tower of the Jiayuguan Pass.
  In addition to the above-mentioned stories about the construction of the Great Wall,there are also plenty of stories about current scenic spots.A famous one is the legend of the Beacon Tower.This story happened during the Western Zhou Dynasty (11th century BC-711 BC).King You had a queen named Bao Si,who was very pretty.King You liked her very much,however Bao Si never smiled.An official gave a suggestion that setting the beacon tower on fire would frighten the King's subjects,and might make the queen smile.King You liked the idea.The subjects were fooled and Bao Si smiled at the sight of the chaos.Later enemies invaded Western Zhou,King You set the beacon tower on fire to ask for help.No subjects came to help because they had been fooled once before.Thus,King Zhou was killed by the enemy and Western Zhou came to an end.
  Beautiful stories and legends about the Great Wall help to keep alive Chinese history and culture.In each dynasty after the building of the Great Wall,many more stories were created and spread.

The Great Wall of China is called the "Ten-thousand-Ii Great Wall" in Chinese.In fact, it's more than 6000 kilometres long. It winds its way from west to east, acrodeserts, over mountains, through valleys till at last it reaches the sea. It is one of the wonders of the world.
The Great Wall has a history of over twenty centuries.The first part of it was built during the Spring and Autumn Period. During the Warring States Period, more walls were put up to defend the borders of the different kingdoms. It was during the Qin Dynasty that the kingdom of Qin united the different parts into one empire. To keep the enemy out of his empire, Emperor Qin Shi Huang had all the walls joined up.Thus, the Great Wall came into being.
The Great Wall is wide enough at the top for five horses or ten men to walk side by side. Along the wall are watchtow-ers, where soldiers used to keep watch. Fires were lit on the the towers as a warning when the enemy came.
It was very difficult to build such a wall in the ancient days without any modern machines. All the work was done by hand. Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth, but of the flesh and blood of millions of men.
Today the Great Wall has become a place of interest not only to the Chinese but to people from all over the world.Many of them have come to know the famous Chinese saying: "He who does not reach the Great Wall is not a true man

最早的长城是楚国建的,叫做方城.为防御北方游牧民族或敌国,开始营建长城,随后,齐、燕、魏、赵、 秦等国基于相同的目的也开始修筑自己的长城.秦统一六国后,秦始皇派著名大将蒙恬北伐匈奴,把各国长城连起来,西起临姚,东至辽东,绵延万余里,遂称万里长城.
1987年12月长城被列入《世界遗产名录》.
中国的长城是人类文明史上最伟大的建筑工程,它始建于2000多年前的春秋战国时期,秦朝统一中国之后联成万里长城.汉、明两代又曾大规模修筑.其工程之浩繁,气势之雄伟,堪称世界奇迹.岁月流逝,物是人非,如今当您登上昔日长城的遗址,不仅能目睹逶迤于群山峻岭之中的长城雄姿,还能领略到中华民族创造历史的大智大勇.
长城位于中国北部,东起山海关,西到嘉峪关,全长约6,700公里,通称万里长城.
长城的修建持续了两千多年,根据历史记载,从公元前七世纪楚国筑“方城”开始,至明代(1368-1644年)共有20多个诸侯国和封建王朝修筑过长城,其中秦、汉、明三个朝代长城的长度都超过了5千公里.如果把各个时代修筑的长城加起来,总长度超过了5万公里; 如果把修建长城的砖石土方筑一道1米厚、5米高的大墙,这道墙可以环绕地球一周有余.
长城的主体工程是绵延万里的高大城墙,大都建在山岭最高处,沿着山脊把蜿蜒无尽的山势勾画出清晰的轮廓,塑造出奔腾飞跃、气势磅礴的巨龙,从而成为中华民族的象征.在万里城墙上,分布着百座雄关、隘口,成千上万座敌台、烽火台,打破了城墙的单调感,使高低起伏的地形更显得雄奇险峻,充满巨大的艺术魅力.
各地的长城景观中,北京八达岭长城建筑得特别坚固,保存也最完好,是观赏长城的最好地方.此外还有金山岭长城、慕田峪长城、司马台长城、古北口长城等.天津黄崖关长城、河北山海关、甘肃嘉峪关也都是著名的长城游览胜地.
中国万里长城是世界上修建时间最长,工程量最大的冷兵器战争时代的国家军事性防御工程,凝聚着我们祖先的血汗和智慧,是中华民族的象征和骄傲.
根据历史记载,从战国以来,有20多个诸侯国和封建王朝修筑过长城.最早是楚国,为防御北方游牧民族或敌国,开始营建长城,随后,齐、燕、魏、赵、 秦等国基于相同的目的也开始修筑自己的长城.秦统一六国后,秦始皇派著名大将蒙恬北伐匈奴,把各国长城连起来,西起临姚,东至辽东,绵延万余里,遂称万里长城,这就是“万里长城”名字的由来.但今天我们所见到的主要是明长城.
秦长城只有遗迹残存.秦始皇为了修筑长城动用了30万人,创造了人类建筑史上的奇迹.长城的修建客观上起到了防止匈奴南侵,保护中原经济文化发展的积极作用.孙中山先生曾评价:“始皇虽无道,而长城之有功于后世,实上大禹治水等”.
汉代继续对长城进行修建.从文帝到宣帝,修成了一条西起大宛贰师城,东至黑龙江北岸,全长近一万公里,古丝绸之路有一半的路程就沿着这条长城,是历史上最长的长城.到了明代,为了防御鞑靼、瓦刺族的侵扰,从没间断过长城的修建,从洪武至万历,其间经过20次大规模的修建,筑起了一条西起甘肃的嘉峪关,东到辽东虎山,全长6350公里的边墙.(但据报道,1990年一个徒步走完长城全长的中国人的计步器显示的是6700公里.)
长城有极高的旅游观光价值和历史文化意义.现在经过精心开发修复,山海关、居庸关八达岭、司马台、慕田峪、嘉峪关等处已成为驰名中外的旅游胜地.蹬高远眺,凭古怀幽,古战场的金戈铁马似乎就在眼前.如今,长城与埃及的金字塔,罗马的斗兽场,意大利的比萨斜塔等同被誉为世界七大奇迹,是中华民族古老文化的丰碑和智慧结晶,象征着中华民族的血脉相承和民族精神.

阅读下文,回答后面的问题。
  余以乾隆三十九年十二月,自京师乘风雪,历齐河、长清,穿泰山西北谷,越长城之限,至于泰安。是月丁未,与知府朱孝纯子颍由南麓登。四十五里,道皆砌石为磴,其级七千有余。泰山正南面有三谷。中谷绕泰安城下,郦道元所谓环水也。余始循以入。道少半,越中岭,复循西谷,遂至其巅。古时登山,循东谷入,道有天门。东谷者,古谓之天门溪水,余所不至也。今所经中岭及山巅崖限当道者,世皆谓之天门云。道中迷雾冰滑,磴几不可登。及既上,苍山负雪,明烛天南。望晚日照城郭,汶水、徂徕如画,而半山居雾若带然。
1.对下面各句中加粗词语的解释不正确的一项是()
A.自京师 风雪 乘:冒着
B.道少半, 中岭 越:飞越
C.而半山 雾若带然居:停留
D.复 西谷,遂至其巅 循:顺着
2.下面对本段内容的理解,不正确的一项是()
A.“自京师乘风雪,历齐河、长清,穿泰山西北谷,越长城之限,至于泰安”句中,连用“乘、历、穿、越”四个动词,准确生动,且富于变化,传神地写出了登山的迫切心情。
B.“苍山负雪,明烛天南”句用拟人手法,赋予静态的青山以人的动态,用语新颖、传神。
C.“望晚日照城郭,汶水、徂徕如画,而半山居雾若带然”句用比喻手法写在山 顶远望、俯视所见,设喻新奇,给人以美的感受。
D.本段内容主要是为下文写泰山日出作铺垫,所以文字虽多,但并非文章重点内容。

解题思路:黄土高原,介于太行山、祁连山、长城和秦岭之间,面积约50万平方千米.这里是世界上黄土分布面积最广的区域.长期的水土流失,形成了高原“沟壑纵横”的地表形态.

(1)从图中看出,黄土高原西起乌鞘岭,东到太行山,南连秦岭,北抵长城;
(2)黄土高原土质疏松,植被破坏严重,一遇雨天,水土流失严重,因此其地表景观是沟壑纵横;
(3)黄土高原上地表景观多种多样,有黄土峁、黄土梁、黄土塬等.
故答案为:(1)太行;秦岭;(2)沟壑纵横;水土流失严重;(3)D.

点评:
本题考点: 黄土高原水土流失的治理.

考点点评: 本题考查黄土高原的范围和景观特点.

我准备去长城.用英语怎么说?

The Great Wall of China-中国的长城
The Great Wall of China
The Great Wall of China is called the "Ten-thousand-Ii Great Wall" in Chinese.In fact,it's more than 6000 kilometres long.It winds its way from west to east,across deserts,over mountains,through valleys till at last it reaches the sea.It is one of the wonders of the world.
The Great Wall has a history of over twenty centuries.The first part of it was built during the Spring and Autumn Period.During the Warring States Period,more walls were put up to defend the borders of the different kingdoms.It was during the Qin Dynasty that the kingdom of Qin united the different parts into one empire.To keep the enemy out of his empire,Emperor Qin Shi Huang had all the walls joined up.Thus,the Great Wall came into being.
The Great Wall is wide enough at the top for five horses or ten men to walk side by side.Along the wall are watchtow-ers,where soldiers used to keep watch.Fires were lit on the the towers as a warning when the enemy came.
It was very difficult to build such a wall in the ancient days without any modern machines.All the work was done by hand.Thousands of men died and were buried under the wall they built.The Great Wall was made not only of stone and earth,but of the flesh and blood of millions of men.
Today the Great Wall has become a place of interest not only to the Chinese but to people from all over the world.Many of them have come to know the famous Chinese saying:"He who does not reach the Great Wall is not a true man."

下列历史事件与匈奴无关的是A昭君出塞B张骞第一次出使西域C秦长城的修筑D张骞第二次出使西域可是长城的修筑不就是为了抵御北
下列历史事件与匈奴无关的是
A昭君出塞
B张骞第一次出使西域
C秦长城的修筑
D张骞第二次出使西域
可是长城的修筑不就是为了抵御北方匈奴的入侵吗?怎么会无关呢

这道题其实没有很好的答案,如果硬要选,只能选D.我是这么分析的:
A昭君出塞是汉元帝为了拉拢匈奴的呼韩邪单于,有关
B张骞第一次出使西域是为了拉拢大月氏人,共同打击匈奴,有关
C秦长城是蒙恬击败匈奴,夺取河套地区之后,为了防北匈奴而修建的,有关
D张骞第二次出使西域是为了让乌孙回到故地,让乌孙为汉朝所用,没有直接关系.不过,张骞自己的说法是,可以间接消弱匈奴的实力.但张骞的说法是否真实准确还是另外一回事.所以,我觉得选D还算是靠谱些
