Li Hua spent too much time playing computer games and he fell behind

others. As a good friend of his, I must do something to help him.

Firstly, I think its very important for him to learn lessons well. He

should spend most of his time on his study instead of computer games. Secondly,

I must tell him that playing computer games too much is bad for his health,

especially for his eyes. So he must give it up. I can play more sports with him

after school. Maybe he will become more interested in sports than computer

games. And then Ill ask him to concentrate more on his study. Of course, I will

try my best to help him with all his subjects. I think I can do it in many fun

ways and let him find much fun in studying. At the same time, Ill ask both his

parents and our teachers to help him, too.

If I try these, Im sure he will make great progress soon.

篇1:游览长城作文800字

全文共 826 字

暑假里,我来到了北京,除了要看奥运会以外,当然还要游览一下北京非常有名,人人都知道的古建筑奇迹——长城咯!

和爸爸商量好之后,我们决定要去长城中最为有名,最为壮观的长城——八达岭长城,之所以叫八达岭,是因为这个地方四通八达,也因为这个地方四通八达,易守难攻,是一个非常重要的战略要地,所以要在这里修筑城关。另外,我们去八达岭长城,也可以顺便游览有名的明朝十三陵等景点。

第二天,我们来到了北京旅游集散中心,坐上了通往八达岭的大巴,我们认识了一位姓夯的导游,它是一位地道的北京人,一路上,他给我们介绍了北京许多好吃的、好玩的,也给我们讲了八达岭长城的“好汉坡”——毛主席的“不到长城非好汉”就是在这“好汉坡”说的。他还告诉我们,明朝有16位皇帝,为什么只有13个陵墓,这是因为,剩下的三位皇帝中,开国皇帝朱元璋葬在南京,还有一位也葬在别处,另外一位至今下落不明,是历史上的疑案……

北京非常大,由东至西坐车要行一个大白天,我们从城中心的天安门附近坐车到八达岭也花了两个半小时。到达了八达岭长城后,我们下了车,一眼望去,真壮观啊!那长城随着连绵起伏的山脉向前曲曲折折地延伸,像一条龙,在云雾缭绕的山峰中飞腾,再向前,就是还没有开放的“野长城”它极为险要,有的斜坡坡度接近垂直,它那张满杂草的断壁残垣,又让人想起那烽火连天的古代战场……看了这长城,然人顿时心胸开阔,豪情万丈!我也抑制不住心中的激情,迫不及待地登上了长城。长城时而险,时而缓,虽然非常陡峭难行,但风景非常优美,每到达新的一个烽火台,人们都会四处观望,所以每到烽火台前面50米,都会被人堵得水泄不通,“前面的人快点儿吧!”“快走呀!”“踩我脚了!”等叫声此起彼伏……

于是,看似只有7、8千米的路程,因为路程的艰险难行,加上每个烽火台前的“堵车”,所以当我们回到山下停车场时,已经过了3个多小时了。

怎么样,听了我的经历,你肯定对八达岭长城有一点点了解了吧,如果你还想了解更多的话,那么就亲自去玩一玩吧!

今天,我们游览了世界闻名的古建筑奇迹――长城

长城是中华民族的象征,它全长一万两千多里,是世界上最伟大的建筑之一。我们游览的是长城八达岭段。当车行到离八达岭不远处时,就已经看到了气势恢宏的长城,随着连绵起伏的山脉向远处曲曲折折地延伸,像一条龙在云雾缭绕的山峰中飞腾。长城上每隔一段距离就是一座烽火台,像一个个巨人手牵着手,担起了保卫中原大地的重任。

我们从长城脚下往上爬,长城并不像我想象的那样陡峭,而是由许多缓坡连接起来,在比较陡的地方都筑有阶梯,阶梯的两旁和中间还装有扶手,一点儿也不难爬。长城上人山人海,还有许多“老外”呢!在不知不觉中,我们已经爬到了第一个烽火,这里让我想起了“烽火戏诸侯”的故事。过了烽火台,我们又继续向上攀登,在山间云雾里,我隐隐约约看见对面的山上有用钢板做成的“同一个世界,同一个梦想”的标语牌。接着往上爬,我们看到了一座碉楼,爸爸说:“这是哨塔,古代哨兵就在这里放哨。”过了哨塔,我们就往回走,来到了“好汉碑”。好汉碑上有毛主席的题词――不到长城非好汉。我们全家在这儿留了个影,便回家了。

“不到长城非好汉”,今天我爬上了长城,当了一回好汉,真开心啊!

长城,这充满古老与神秘气息的地方,此刻,它在我脚下。

步上坚固的石阶,周围充满了自然的气息――崇山峻岭、绿树环抱。这长城宛如条长龙在这山中蜿蜒。上千年的历史,这座饱经风霜雨雪的古老建筑仍显刚强坚毅。初踏长城,心中既激动又感慨,激动是因为我将踏上的是举世闻名的万里长城,而我又感慨这长城是由多少汗水、泪水甚至生命换来的,这是多么大的代价啊。但它是中国的骄傲,也是每个中国人的骄傲。

我怀着这份心情,向前走着,让我增强了几份神圣的感觉。有人说:重要的并不是到达目的地,而是欣赏沿途的风景。的确,周围有着如此美丽的风景,谁又在乎下一站又是哪里。在这里,我觉得每一秒都不是虚度。我更希望时间凝固,让我屏气凝神仔细欣赏这里的一草一木。似乎美丽已不能形容它,完美才是对它最好的诠释。

渐渐的,日落西山,夕阳西下,今天的旅行也将落下帷幕。人生就是如此,在达到一个目的地后,就便会有另一个追求。太阳东升西落,日复一日,年复一年,生作文四:游长城

The Great Wall of China

The Great Wall of China is called the "Ten-thousand-Ii Great Wall" in Chinese.In fact, its 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."

中国长城

中国的长城汉语中常叫作“万里长城”。实际上它长6 ooo多公里。它从西到东,穿过沙漠,越过高山,跨过深谷,蜿蜒而行,最后直到海边。它是世界上的奇观之一。

长城有两千多年的历史。最早是在春秋时期开始修筑的。战国时期,各诸候国为了保卫自己的边境,分别修筑了更多的城墙。在秦朝时,秦国把各诸侯国统一起来,成为一个帝国。为了御敌于国门之外,秦始皇令人把所有的城墙连接起来。这样,长城就形成了。

长城上面很宽,足够五匹马或10个人并排而行。沿城墙有许多烽火台,过去常有士兵驻守。敌人来时,就点燃烽火,以通知其他士兵。

没有任何现代机器,要修筑这样一座长城是非常困难的。所有的工作都不得不用手来完成。成千上万的人死了,被埋在自己修建的城墙下面。长城不仅是用石头和土筑成的,而且也是用数以百万计的人的血肉筑成的。

今天,长城不仅对中国人,而且对来自全世界各地的人们来说都是一处名胜。其中许多人都已知道这句中国名言:“不到长城非好汉”。

Different people have different career outlooks. Some people want to become

of being freelancers, and so on.

However, my ideal job is teaching. Firstly, I’m told that teachers have a

high income. With the high income, I can open a training school to help the

children in poor families with their education. Secondly, teachers always have

summer and winter holidays, thus I will have more free time to relax myself.

More importantly, teachers are angels to students, who can pass on the knowledge

to students as well as help them develop their hobbies and interests. I can’t

imagine how happy I will feel when I see my students become elites.

In order to be a qualified teacher, I should read more books to acquire

这个暑假,我有幸去了北京,游览了不少风景名胜,回想起来,还是记忆犹新,意犹未尽,久久难忘。最让我震憾是八达岭长城!八达岭长城真是太雄伟壮观了!

我和爸爸妈妈站在八达岭长城的入口处,只见巍峨的长城犹如一条巨龙弯弯曲曲地盘在山上。望着远处的山顶上黑压压的蚂蚁般的人们,心里不由得惊讶:真是人山人海!长城上的风景到底是怎样的呢?我的心里充满了疑问,带着这个疑问,我向长城迈开了脚步。

长城的阶梯很陡,没有阶梯的地方都是陡坡,非常难爬。于是我就抓住扶手一点一点往上挪。长城的整座城墙用花岗岩条石和特制城砖砌筑而成,高大坚固。墙顶分段设置敌台、垛口和射洞,还特设有排水系统。我还看到了我身后爬过的那几段长城,现在它显得那么渺小。弯弯曲曲的城墙,一直到山的最远处——不管我怎么踮脚,怎么蹦怎么跳都看不见尽头,只能看到若隐若现的烽火台。八达岭地区山势险要、城关重叠,作为军事防御可谓固若金汤。古代的人们可真是了不起呀!

据导游介绍:长城是我国古代伟大的军事工程,也是中国人的骄傲和中华民族悠久历史的象征。它东起山海关、西至嘉峪关,蜿蜒一万两千多里,故以“万里长城”闻名于世。中国首建长城于公元前7世纪,秦始皇于公元前221年统一中国后耗费巨大人力物力,以“修万里城,筑万里人”的代价完成了这一宏伟工程。从此万里长城巍然屹立于世界东方,经历了千百年的风霜雨雪。八达岭长城是北京地区的长城制高点,是居庸关范围内的北口。因“出居庸关,北往延庆州,西往宣镇,路从此分”,故名八达岭……

快到中午了,头顶的太阳火辣辣的烘烤着大地,我们满头大汗。每上一个台阶都要用尽全力,腿好像灌了铅,抬都抬不起来。可一想到“忍耐和坚持是痛苦的,但它会逐渐给你好处”这句话,我就又开始爬。

历经千辛万苦,我们最终终于气喘吁吁地爬到了我和爸爸自己的终点。“不到长城非好汉”,我高声大喊,“我也是一个好汉啦!”
