NO.1 初识网络

在我刚刚接触网络时，是在3岁。

那时我家买了新电脑，小小的我被那个神奇的鼠标迷住了。看着那个闪着光的小鼠标在电脑频幕上一点，就会蹦出来一个个丰富多彩的画面，一会儿是搞笑滑稽的唐老鸭“嘎嘎——”地叫着冲来跑去；一会儿是善良美丽的白雪公主跳着优美的舞蹈；一会儿是不怕困难、聪明机灵的喜羊羊智斗灰太狼。每当看到这些时我就情不自禁的拍起了小手，又蹦又跳。话还说不全的我竟喜欢上了电脑！经过一个多月的“修炼”我无师自通，不但会开机关机、自如地打开网页和关闭网页，更让妈妈感到不可思议的是，我竟然会玩一些简单的小游戏了。

才刚刚3岁的我让妈妈感到惊奇的同时，也有了一些担心。妈妈告诉我，我现在还小，视力没发育好，不能玩电脑。虽然还不太懂妈妈的话，可好奇心浓厚的我依然钟情于那个轻轻一点就会蹦出小人儿的“方盒子”。

NO.2 迷恋网络

渐渐地，在我7、8岁时，我已成为一名“电脑高手”甚至超过了爸爸，有时爸爸还得向我请教呢！

由此，电脑与我结下了不解之缘。随着年龄的增长，我学会了打字、查资料、看新闻，还会玩一些比较复杂的智力游戏和单机游戏，还有了自己的QQ号，没事儿时还能和同学朋友在网络上交流，那种感觉，啊，真美！看着电脑里那丰富多彩的画面，无穷无尽的知识，心里有一种说不出的感受。我非常感谢发明网络的那个人，它给我们带来了多少方便啊！我无法想象，离开电脑，离开网络，我该怎么办？

随着科技的发展，网络内容也越来也丰富，只要你轻轻一点，没有它解决不了的问题。我对网络的痴迷和依赖也越来越重，查资料找它，玩游戏找它，看大片找它……生活中有许多事情都离不开它。我无法摆脱电脑对我的诱惑，我的心早被电脑牵走了。面对我对电脑网络的不正常状态，我们家的首席“总监”——妈妈适时的和我进行了谈话。“总监”说电脑网络是个好东西，是良师、是益友，只要能正确使用它，就能给我带来巨大的帮助。可是里面还隐藏着不可预知的陷阱和魔鬼，有时你不小心点开那些非法网页，就会自动蹦出一些“少儿不宜”的画面，或者侵害电脑的病毒，还有一些暴力游戏和诱惑你不断充钱的游戏等等。所以，为了我的健康成长，我和妈妈共同规定：健康网络1小时的计划。要求除了正常的学习需要，每周上网控制在一小时。

NO.3 邂逅校讯通

直到我上三年级时，李老师让我们每人都参加一个叫校讯通的东东。当我注册后才发现，校讯通就像一个“家”，一个温暖的“家”，一个让我永不舍弃的“家”。

在这里，我认识了很多朋友。有老师，有家长，有小博友，还有校讯通的叔叔阿姨，他们都是我最亲最近的“家人”。每天，不管多累，我都会到“家”里看看我的“家人”，欣赏欣赏我的“家人”发表的，在他们的里和他们一起开心快乐，并写下我的感悟和对“家人”的祝福。我还会参考和学习一下他们的一些写作方法和经验，并用留言的方式留下我的困惑和感悟与大家一起探讨。我有时还用日记的方式记录我每到一个地方的新奇见闻、所想所感、喜怒哀乐，不管是开心的、快乐的、烦恼的，还是悲伤的，我都用键盘打成一行行文字，做成一张张美丽的图片和我的“家人”分享。在这里，我得到了无数从未谋面的“家人”的关心和爱护；在这里，我体会到了成功的喜悦和幸福；在这里，我从一个蹒跚学步的写作菜鸟成长为班级博客之星；在这里，无数关爱我的“家人”激起了我浓厚的写作兴趣，树立起我对写作的坚强信心……

校讯通，让我在电脑网里开辟了一片崭新的天地。它就像一片充满生机的绿洲，在我用心血和汗水的真诚浇灌下，焕发出生命的光彩！

电脑网络，已不再是我玩游戏、看动画的专属，它已经是我生命的一部分，因为它让我体会到了成功和幸福……

感谢网络！感谢校讯通！

The Great Wall of China is called the "Ten thousand Ii Great Wall" in

Chinese. In fact, it s more than 6 000 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 dif ferent

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 watchtowers, 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."

At the beginning of the summer vacation, our family of three returned to my

hometown, Shehong.

Back in Shehong, we stayed at my grandmothers house. One Friday morning,

my brother and I made an appointment to catch cicadas in the bushes downstairs

at their house because they have a lot of cicadas there. Before night, I rushed

over and saw that my brother was already there waiting for me, with a prepared

pocket in his hand.

We walked cautiously into the bushes, for fear that our every move would

disturb the cicadas on the trees. At this time, the cicada was screaming

"knowing" and "knowing", as if they were holding a wonderful concert. I walked

very carefully under a big tree and found a cicada lying in the middle of the

tree pole, screaming happily! I grabbed it after thinking about it, and covered

it with my hands. I wasnt nervous before, but at this time I was extremely

nervous, and my heart was jumping like a little rabbit, for fear that the cicada

would fly away all of a sudden. As a result, as soon as my hand touched the

branch, the cicada flapped its wings and flew away nimbly. The elder brother

said: "Look at me! I can definitely catch the cicada." While talking, the elder

brother found another cicada on the tree. He raised his hand high, moved his arm

gently, and when he was about a decimeter from the cicada, his brother suddenly

covered it, and suddenly he covered the cicada in the palm of his hand and put

it in a bag. Next, my brother caught five cicadas in the same way. I really envy

my brothers ability to catch cicadas.

Watching my brother catch so many cicadas, can I not feel itchy? So I said

to my brother: "Brother, you can rest for a while, Ill catch it." I handed the

bag to my brother and learned his method. After a while, I caught one. Before

long, we had more than twenty cicadas in our bags.

Watching these cicadas stay in the bag obediently, my brother and I both

laughed happily, and the cheerful laughter echoed in the trees for a long

time.

China had cause for a double celebration on Saturday after winning their

first ever swimming gold medal as well as setting a new world record in the

womens 400m medley.

Sun Yang sealed a place in Chinas Olympic history with an impressive swim

in the 400m freestyle final that was only 0.07 seconds off the world record to

take gold.

Defending Olympic champion Park Ta-Hwan was leading at the final turn, but

the 20-year-old Sun surged past his South Korean rival in the final length to

seal a place in Chinese Olympic history.

"The feeling is very nice, its beautiful. Its a big dream come true for

me," said Sun.

"Because its the Olympic Games, I felt a little bit nervous at the start,

and then at the end, I felt that I could get a medal."

Twenty minutes after Yang won Chinas maiden gold medal, 16-year-old Ye

Shiwen triumphed in the womens 400m medley, as well as breaking the world

record set in Beijing four years ago.

Ye rounded off a sparkling day in the pool for China as she claimed the

title with a breathtaking final lap of 28.93 seconds.

"I thought at the 200 meters that the race was lost, but then I realized I

was in the top two or three and I was confident I could win on the last leg,"

said Ye.

"I dreamed of winning the gold medal, but I never ever expected to break a

world record, Im overwhelmed."

A little monkey picks up a pumpkin and wants to take it home.But the pumpkin is toobig.The monkey cant take it home.

Suddenly he sees a panda riding a bike towards him. He watches the bike. "l have a good idea. I can roll the pumpkin. It likes a wheel."

So he rolls the pumpkin to his home. When his mother sees the big pumpkin, she is surprised and says, "How can you carry it home?" The little monkey answers proudly, "l cant lift it, but l can roll it." His mother smiles and says, " What a clever boy!"

Depending on personal experience, personality type and emotional concern,

we find that some people hold the idea of living in the country, while others

prefer living in the city. In my opinion, I prefer the city life, though it has

advantages and disadvantages.

First of all, city life is very colorful. City is the center of the

surrounding area. So, it is also the most booming place having the best things.

There are many great things and wonderful activities in the city, while there

isn’t in the country. For example, there are KFC, wonderful shopping mall,

delicious food from various places, dancing club, different kinds of activities

and so on. We can also learn the culture from all the countries. Despite city

life is so wonderful, it still has many disadvantages. Nowadays, with the

improvement of people’s living standard, people have more cars and more people

come to city, and then the city becomes more and more crowd. As a result,

traffic jam emerges, which makes great inconvenience for people to go out.

What’s worse, the air pollution becomes serious day by day, which is bad for

people’s health.

To sum up, every coin has two sides. Living in the city also has good side

and bad aspect. Whether like living in city or not depends on individual

thinking. As myself, I like living in city though I know the disadvantage of

living in city.

我们都知道，有许多少年因为网络游戏而迷失了自我，失去了原来的健康活泼，积极向上，我们可以看到他们迷上电脑之后有多么痛苦，我看见网上有许多的例子，像有一位同学因为迷上了电脑所以变卖家电，是他的家长不得不把手提电脑没收让他找不到，于是这位同学几次报警，谎称家里电脑被盗， 最后因为因谎报警情故意扰乱公共秩序，目前被警方依法给予行政拘留5天的处罚。有了上面的前车之鉴，我们知道，其实玩游戏是一种可以令人上瘾的东西，类似毒品。

但是正处于小学阶段的我们也渴望有一片属于自己的天地，加上应试教育的作业压力，我们不得不想到玩电脑游戏来弥补这样的心理。可是缓解也要有一个度，我们不能主次不分，我们的主要任务还是学习，而不是让我们去专门的玩电脑。假想一下，如果全世界的人们如果全部都在玩电脑游戏，没有人工作，没有人学习，拿这个世界将会乱成什么样子?我们不得而知。但是这将是一个多么令人恐惧的世界啊!电脑游戏不是生活的全部，它只是生活的一部分，他是一种很好的交流工具，人类有了它就能随时随地地获得信息.因此，就有越来越多的网络游戏出现。有部分电脑游戏是以暴力或是其他不良信息作为主题的，当学生玩这种游戏时，就会被灌输这样的想法。 现在网上有许多骗人的东西，已有不少人上当受骗了，我觉得，我们应该有一颗警惕心，防止一些坏人的犯罪行为。

我认为，上网最主要的目的应该是查找资料，而不是一味的玩游戏，沉迷游戏，这是不好的。万一沉迷于玩游戏，就会影响许多方面的问题。例如学业、与别人沟通等等。所以我们应该坚决反对沉迷游戏。 有一次，我在电视上看到一个男孩，因为沉迷网络游戏，天天都不回家，在网吧通宵上网。家长与学校也已经多次劝阻，可还是屡教不改，最终因过于沉迷游戏，导致精神失常，伤害了别人。 沉迷网络游戏是一种不好的行为。作为学生的我们，应该把精力放在学习上，而不是沉迷与上网玩游戏。我相信，只要我们努力，就一定能将这种不良风气消灭的!

As can be seen from the picture, a man with an ax on his right side sitting on a stump just wants to cut the flourishing big tree under the beautiful sunshine when suddenly the tree raises its hand to stop him. What does this drawing intend to tell us? That is to tell us that we should put forward on protecting trees and our forests.

As is known to us,the areas of our forests are becoming sharply less and less.Some selfish people are eager to obtain self-interests from cutting trees ignoring the serious consequences.Trees are humans friends and they are extremely hlepful to us.They are not only bring us shade in hot summer but also prevent cold wind in winter. Whats more importance?they can preserve good soil .Just imagine what would be like if the soil were rushed off leaving only sand instead.Thats very terrible!

To serve as responsible stewards of the planet,we must be awaken to what we are engaging in,we should accacelerate our pace to protect our forests.The Earth that we have is unique,let the fresh flowers bloom on it everywhere!

comfort in the family.On the other hand,getting together is a symbol of

blessedness and auspiciousness.People in other country dont have this

occasioned by different culture between two countries.

春节

农历新年对中国人来说是个很重要的节日。它大约要持续4天，在这期间，除了值班人员外，人们都放假了。工人不开工，学生上不学，商店关门。

新年前几天人们就开始准备。农民们宰杀猪、鸡、羊。城市居民买肉、鱼、蔬菜。人们打扫房子，贴对联，挂彩灯。

新年除夕，各家各户围坐在一起吃团圆饭。饭后，人们看电视，到了午夜12点，在这辞旧迎新的时刻，人们燃放各种烟花炮竹来庆祝。新年第一天，即正月初一，所有的人都穿着最漂亮的衣服，路上相遇，互相道“新年好”，亲戚朋友拜年互赠礼物，孩子们尽情地玩耍。

Recently, global warming has become a hot topic among people. It results

from serious air pollution. As the environmental pollution is more and more

strict, the temperature of all the world has dramatic increased. Gradually, some

disaster such as drought, floodandGlaciers Melting follow. How terrible it is!

Therefore, we need to protect our earth and fight against the disaster

together.We should start from the trivial side. Making contribution to

protecting our home.

China, as a developing country, has a large gap compared with developed

countries. If we want to catch up with and even surpass the developed ones,

education seems important and should be given the first priority. Besides,

education seems the same important to individuals.

In modern time, when science and technology are making great progress, the

education of the work force is the most important. Moreover, many of the success

in advanced countries have demonstrated that a nations prosperity mainly

depends on the quality of its labor force, namely those who have been well

educated.

For individuals, education is the best way to improve oneself. Firstly,

its education thathelps people gain basic knowledge of the world, helping them

to distinguish what is right and wrong. Secondly, education improves ones

skills of life and work, which can make people live a good life or have

achievements in career. Finally, education brings people ability of learning and

that is the key role of education.

Nowadays, more and more middle-aged people are suffering from insomnia, as

life for the middle-aged is stressful indeed. For one thing, as they are the

backbones of their companies, they have plenty of things to do at work. And they

usually have to work overtime. For another, they have to take great

responsibilities at home, for their aged parents need to be supported and their

little children need to be brought up. Thats why they dont have enough time to

have a good rest.

To sleep well, some of them often take sleeping pills. I dont think its

good for them to do so, because the sleeping pills can only get rid of the sign

of insomnia, not the cause. And taking too much sleeping pills is bad for their

health.

Therefore, I suggest those middle-aged people should know how to relax

themselves and rest their brains. Taking a simple work after supper will be

beneficial for them. Besides, they can have a glass of milk before going to bed,

which can be helpful for their sleep.

The Dragon Boat Festival is a lunar holiday, occurring on the fifth day of the fifth lunar month holiday, occurring on the fifth day of the fifth lunar month

The Chinese Dragon Boat Festival is a significant holiday celebrated in China, and the one with the longest history .

The Dragon Boat Festival is celebrated by boat races in the shape of dragons.

Competing teams row their boats forward to a drumbeat racing to reach the finish end first.

The boat races during the Dragon Boat Festival are traditional customs to attempts to rescue the patriotic poet Chu Yuan.

Chu Yuan drowned on the fifth day of the fifth lunar month in 277 B.C. Chinese citizens now throw bamboo leaves filled with cooked rice into the water.

Therefore the fish could eat the rice rather than the hero poet. This later on turned into the custom of eating tzungtzu and rice dumplings.

Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.

Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.

Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.

In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day

So many children take what their parents do for them for granted, they

haven’t realized the meaning of being grateful. So they always get angry with

their parents, because they don’t get what they want. According to the news that

a little girl went out of the house and refused to go home because her parents

did not give her enough pocket money. I was so shocked to hear it, I would never

ask much from my parents, because I knew they were not easy to make a living and

I am always feel so thankful for what they offer me. Even the one who gives me a

hand when I am in need, I would remember him and when I have the chance, I will

return. A grateful heart makes us a kind person and create a harmonious

environment.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。
