The language develops as the media become various, many years ago, people used the language that was very formal, because most oral language was always the same as the paper language. But as the time by, people started to use computer, they shared the information, at the same time, many new language was created. The Internet language is in favor by people, they like to use it, because it is fashionable and very appropriate to express what they mean. I like to use the Internet language, it is so new and fun, what’s more, it is convenient, like I can use the shorten words instead of the long words. The problem of the Internet language is that it is very informal, it can’t be written in the paper, it will changes as the time goes by. In my opinion, we can use the Internet language in informal occasions.

语言的发展伴随着多媒体的多样化，很多年以前，人们使用正式的语言，因为大部分口语和书面语言差不多。但是随着时间的流逝，人们开始使用电脑，他们分享信息，同时，很多新的语言被创造出来。网络语言为人们所喜爱，他们也乐意使用，因为这很时尚，也能恰当地表达人们的意思。我喜欢使用网络语言，那很新鲜和有趣，而且，也很方便，比如我可以使用短的词来代替长的词。网络语言的问题在于非常不正式，不能书面书写，网络语言也会随着时间而改变。在我看来，我们可以在非正式场合使用网络语言。

现代信息网络技术的发展，尤其是互联网在中国的迅速发展，使中国人的社会存在方式大大地扩展与延伸，使中国开始步入互联网时代。互联网是一种新型媒体，它具有的互动多媒体的效果对未成年人产生了极大的吸引力，必然也对未成年人的思想道德产生了巨大的影响。这种影响有积极的一面，也有消极的一面。未成年人是指未满18岁的特殊群体。一般而言，他们的知识和阅历还不足以明辨是非，他们的世界观、人生观和道德观还没有成熟，还不足以抵制不良社会风气、习惯、观念和事物的影响。网络是一个信息的宝库，同时也是一个信息的垃圾场，学习信息、娱乐信息、经济信息以及各种各样的黄色、暴力信息混杂在一起，使网络成为信息的花筒。

互联网可以为我们提供各种学习的机会。互联网最大的用处就是它能给我们提供丰富的信息资料，传递信息。

互联网上有很多不良信息、毒害我们的心灵，存在大量淫秽文章、图片、电影和动画。即便一些正规网站，为了提高访问率也发布一些裸露的写真集，用挑逗的字眼和图片吸引网民访问。这些低级趣味的信息一旦被未成年人访问，就会很快侵入原本美好的心灵。许多孩子的堕落就是从偶尔看一次黄色录像，偶尔浏览一下色情网站开始的。一旦陷入，父母的打骂甚至哀求、老师的教育劝导都很难让他们回头。互联网上的网络游戏、虚掷光阴。网上有各种各样的游戏，其中不乏黄色、暴力的游戏。未成年人对游戏的痴迷超乎想象。网络游戏不再只是游戏，它还可能吃人!一个少年的沉溺，意味着一个幸福家庭的毁灭。记的电视上曾经报道了个节目，一个15岁的少年整天弥恋在电脑游戏中，原本他的学习成绩很好，自从爱上了电脑游戏后成绩一落千丈。再后来他每天上课注意力不集中，经常缺课。有1次居然在网吧里连续打了10天没喝一口水，吃的是方便面，他简直是达到了走火入魔的地步。后来他觉得无脸见老师同学，对不起他的爸爸妈妈就吃老鼠药自杀了。死前还写了一封信，名叫“天堂的来信”。1位15岁了少年就这样的去了，这篇报道告诉了我们小学生现在最重要的是学习，不要每天沉浸在电脑当中，否则将会一事无成!

互联网网络一半像是天使，一半像是魔鬼。一方面为我们开拓了知识的新领域，丰富了文化生活;同时，含有色情、暴力、赌博、愚昧的迷信和落后文化与有害信息传播，严重威胁着未成年人脆弱的心灵。

最后我还要告诉人们：电脑是可以玩的、互联网是可以上的、只要我们不去浏览一些色情网站、不陷入游戏中、我们就不会家毁人亡。

As a product of modem computer and the Internet，online games have won great popularity among people，youngsters in particular.However,some people believe that young people who lack self-discipline can easily get indulged in these games and their health and academic performances are severely affected.This phenomenon can be found on TV reports from time to time，and many teachers and parents have expressed

However,some others argue that online games are not always harmful.They can train the ability of youngsters to respond to things quickly.  Moreover,they Can stimulate their imagination and their interest in computer science.More importantly,it does bring people much pleasure and satisfaction，and release their pressure greatly.

From my point of view,online games are a wonderful entertainment if you play them in a reasonable way.When they interfere too much with your life，you’d better give them up at once.Yet if you have enough self-control over them，you can certainly obtain real pleasure and benefit a lot from them.

[网络游戏危害英语作文

It can be seen that some students are addicted to computer games， and the number of them is keeping rising. They always spare their learning time to play computer games，which leads them to ignoring their studies. They just surf the Internet and play computer games， so they even dont know how to communicate with others in reality. It is such a big pity that it is time to take some measures to limit computer games.

First， the teacher should be responsible for educating students to leave away from computer games. Teachers should try to make students realize the original dangers of computer games. Second，the government should check the Internet cafes at times in order to let the runners run their business legally. Third，it is necessary to make some laws to forbid the game developers to create some harmful games for students.

In a word，if the three ways above are put into practice effectively， it is certain that fewer and fewer students have interest in computer games.

从20世纪80年代开始，迅速发展的IT技术在二十多年的时间里彻底改变了这个世界。人们开始习惯于生活中无处不在的网络：从现金到信用卡消费，从面对面的交易到网上订单，从阅读报纸到浏览网页……然而看似便捷、祥和的网络世界并不安全，我们时常会受到不良干扰，成为网络世界中的受害者。

目前，网络犯罪的势头有愈演愈烈之势，已经成为电子商务时代的最大隐患。2000年1月的6~9日，黑客们发动了一次被称为“网上珍珠港”的偷袭战，对雅虎、亚马逊网上书店、CNN等美国八大著名网站发动了一连串袭击，致使各大网站瘫痪长达数小时。欧洲和我国香港地区的一些网站也遭受到黑客袭击。据统计，4天的攻击造成了约12亿美元的经济损失。而且实际上，没有人真正了解网路犯罪到底严重到何种程度，因为大部分的攻击都没有被发现。据美国联邦调查局估计，计算机犯罪造成的各种损失每年合计高达100多亿美元。

国际范围内的网络犯罪与作为普通用户的我们似乎很遥远，但事实是否如此呢?前一阵子，炒得沸沸扬扬的“艳照门”事件在整个中国乃至整个世界都掀起了一阵轩然大波。网络作为事件传播的主要工具，被各种各样的人利用起来，给电脑前的用户们以一次巨大的冲击。大量淫秽图片被各网站收录，提供人们免费下载，有的甚至被制成“压缩包”在用户中赠阅。到面前为止，有很多人电脑里还保存着这些不雅图片以作“纪念”。网络，这个如今社会最流行的传媒，传递着的不良信息败坏了社会风气，冲击着人们的道德底线，给下一代的青少年造成了消极的影响。网络安全问题离我们很近，当我们轻轻敲击鼠标时，其实就在做着“安全”“不安全”的选择题，在分秒之间安全就会成为危险。

在国际刑法界例举的现代社会新型犯罪排行榜上，计算机犯罪已名列榜首。哈尔塞说过：“互联网可以做每一件事情，它可以做为你量身定做的事情，可以做你需要它做的任何事情。”如此看来，网络世界仿佛变得如黑洞搬深不可测。难道我们就要远离网络?答案是否定的。信息时代的人们只要努力做到“魔高一尺，道高一丈”，就能防患于未然。

网络建设者应加强网络漏洞的修补，且广纳贤才，让有识之士在正确的道路上施展自己的才华;普通的用户则应提高自身的思想道德修养，自觉抵制不良信息的侵扰，且勇于揭露网络不文明行为。只要社会、个体一起努力，我想安全的网络世界离我们并不遥远。

我们要警惕不安全网络，为建设和谐的网络世界贡献自己的一份力量!

With more and more cars coming into our families, we are

With more and more cars coming into our families, we are happy that it has greatly improved our life. But unluckily, it has also brought many problems, such as heavy traffic and traffic accidents。

Traffic safety is everybodys business. We must obey the rules. For example, we must walk on walk side, when we cross zebra – crossing, stop and look right and left, then go across fast. Don’t play football on the road .we can tell our parents not to drink before they drive, not to run through red lights, not to talk and laugh while driving etc。

We can say cars are coming into our life, but only when everybody thinks traffic safety is everybodys business can we be safe driving on roads and walking on sidewalks.

My dear schoolmates,

There is no denying that safety plays an important part in our daily life. Recently our school has carried out a program aimed at making our campus a safe place to stay on. I considered this as indeed a good practice, which will make us aware that safety should come first in our daily life, whether when we stay at school or outside it. When we are doing sports, we should attach importance to the safety and avoid being hurt.

Furthermore, when we get into trouble with our classmates, we should remain calm and avoid any form of fighting, which may only bring suffering and pain to us mentally and physically.

As far as I’m concerned, I feel all the students and teachers should work hard and creatively to keep the “Safe Campus” activity in mind. Besides, we are supposed to

observe the law discipline wherever we are. Let’s start right now and spare no effort to do little bit every hour and I hope we have a good time everyday!

Thank you!

目前，一些诸如GG、MM、 Xia Mi 等网络语言在青少年中极为盛行，并且出现在家庭作业报告，甚至全国入学考试的作文中。请你以 “Should Internet Slang Be Prohibited (禁止)?”为题，根据下表内容用英语写一篇短文，并谈谈你自己的看法。

注意：

1. 短文开头已经给出，不计入总词数; 2. 词数：100-120左右 【参考范文】

Should Internet Slang Be Prohibited?

At present， Internet Slang， such as “GG， MM， Xia Mi”， has become popular among the teenagers.

There are different opinions on Internet Slang. Some students think Internet Slang is vivid， fashionable and full of humor and intelligence. Besides， it makes chatting on the Internet quicker.( 万业宝 www.wAnyEbao.CoM )

However， some other students think Internet Slang lacks depth of thought and is too simple. Also， it is hard to understand and not accepted by most people. The words sometimes might make people confused， even resulting in misunderstanding.

Every coin has two sides. In my opinion， living in the Information Age， if we don’t know the Internet Slang， we seem to fall behind the times. It will be OK as long as these terms are used correctly in proper situations.

沉迷网络游戏

题目：李华沉迷于电脑游戏中，影响了学习。作为他的好朋友，你打算怎么帮他呢?请用下面所给的提示词写一篇不少于80字的短文。字迹工整，语言流畅。

提示词：give up concentrate on be (become)interested in

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 it’s 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.

In light of recent celebrity photo leaks from their cloud accounts, one major topic at this years China Internet Security Conference is cloud security. People have all heard the term "cloud" so many times, but what exactly is it?

The cloud refers to software and services that run on the Internet instead of your computer. Apple’s iCloud, for example, is a popular cloud service, as well as Dropbox and Google Drive.

The advantages of using the cloud? First, you can access your documents, photos and videos from anywhere. Your home, the office, on the train, as long as you’re connected to the Internet. You can also access your files from multiple devices like an iPhone, an iPad or a computer. And to make things even better, you don’t have to worry about backups, because most cloud services automatically saves your data for you.

The only problem is, when you a file from one device, make sure it’s d from the cloud too. Otherwise, a copy of it will be left in the cloud.

如今，互联网在社会上越来越普及，网络道德与礼貌也日益重要。网络虽是虚拟世界，但仍要讲究道德与礼貌。

在现实生活中，人们相互交往时都很注意讲文明、讲礼貌，愿意展示自己有文化、有修养、有良好品行的美好形象。

在虚拟社会中，人们交往互不谋面，可能交往的双方永远不知道对方是谁。这样，是不是就可以不讲礼貌，可以信口开河、脏话连篇呢?不能!在网络这个虚拟社会中，由于人与人之间的交往一般都是书面语言进行，所以谦和的态度、礼貌的语言、相互的尊重就显得更加重要，它会使人感到温暖亲切，能自然地拉近双方的距离，消除陌生感，从而使交往的双方友善地进行沟通。文明礼貌的言行举止会帮你在网友间架起友好交往的桥梁。

如果开口骂人，说脏话，只会使大家厌恶，觉得你没修养。这种人在社会上和网络上是没有立足之地的。据《楚天都市报》报道，荆州市有两个中学生用QQ聊天，其中一个说脏话，另一个便将他拖进“黑名单”里。那个骂人的便用“珊瑚虫”版QQ查到对方所在的网吧、机号，约上几个同学，找到他，把他活活打死了。后来被法院抓到，被判了刑。

讲道德，不仅仅涉及到不讲脏话，还必须言而有信。如果瞎回帖子，会让别人信以为真，做错事，害人害己。

另外，由于我们青少年正处于成长时期，阅历少，经验不足，在网络这个缤繁世界游历时，一定要注意树立自我保护意识，在自己的头脑里建立起“安全防火墙”，以抵御不良信息对我们的影响。标明限制信息的，如果自己处在限制区域内，一定不能进入。

再举个例子，我的几个同学在网上发现了一个打打杀杀的，叫什么《闪客快打》的游戏，打开时明明显示着“本游戏含暴力因素，未满18岁禁止进入”，但他们却固执地闯进去玩起来。由于玩多了，他们一看见同学就想冲上去打上几拳或踢上几腿，学习也直线下滑。这是多么可悲的事儿呀!我们一定要吸取教训，不看未成年人不适宜的信息，不玩不适宜未成人的游戏。

上网必须用自己注册的账号和密码，未经允许绝对不能盗用他人的账号和密码，加“好友”时要经过对方的允许与验证。别人在输入账号和密码时，要自觉回避，不能偷看，这是一种基本的美德。

别人制作的网页、动画，撰写的文字等都是制作人的知识产权，是受国家保护的，未经允许绝对不能转载，署上自己的名字。

再谈谈安全问题。目前网上有不少骗子，利用儿童的轻信和好奇心约会儿童到某地会合。这样的事儿即使你认识对方，也必须和家长商量，时刻都不能放松警惕。最重要的是，不管什么时候，都不能轻易将个人资料发布在网上。

好了!愿大家合理安排时间，在网上无忧无虑，安全地畅游!

Every year a lot of people got injured or died in traffic accidents. It is reported that many accidents resulted from people’s breaking of traffic rules. So it is necessary for all to keep the traffic rules in mind and obey them strictly.

When one crosses the street, one should take the crosswalk, underground passage or pedestrian overpass. If one is riding a bike or motorcycle, keep riding on the right side of the road. When the red light is on, please stop and wait until the green light is on. Give a hand signal if one wants to turn or stop. It is important to let the children know that playing on the road is very dangerous. Helping the aged and children cross the road is always a kind deed.If everyone obeys the traffic rules, it will be much safer to walk or ride on the road.

每年很多人受伤或死于交通事故。据报道,许多事故是由于人们违反交通规则的。所以有必要记住交通规则并严格遵守它们。

当一个人穿越马路,要走人行横道、地下通道或人行天桥。如果一个人是骑自行车或摩托车,骑在路的右边。红灯时,请停止,等待绿灯。给一只手如果一个人想把或停止的信号。重要的是要让孩子们知道在路上玩耍是很危险的。帮助老人和孩子过马路总是一种契约。如果每个人都遵守交通规则,这将是更安全步行或骑在路上。

Along with the time development, accessing the net already turned the extremely universal matter. No matter is adult or the child, so long as mentioning the computer, all think of internet. But, accessing the internet is advantageous ,but also has shortcoming.

I knew very many people access the net, mainly is for playing games, which is very bad for the study. Therefore, some people believed, the elementary and middle school students lack the self-control.

But,there are many people approving to accessing internet, why? Because internet can provide to the people very helps. First, the network looks like a library, we can look up very many materials easily,and it is quicker than the speed of consulting books; Next, we may read a richer news on-line; In addition, accessing the net also has other functions, for example, E-mail, telephoning on the net and so on.

Actually, accessing the net has its profit and the shortcoming place. We use it to open to expand the field of vision, the study knowledge, but must certainly grasp the discretion.

Currently, many problems concerning the safety of food have popped up. As for me, I believe at least three factors account for this issue.

目前，有关食品安全的许多问题都出现了。至于我，在这个问题上至少有三个因素的相信我。

First, I observe that profits drive many food producers to commit illegal things. They aim to gain more money at the expense of consumers’ health. Second, the overuse of agricultural pesticide has resulted in the degradation of food quality. The excessive pesticide bears enormous health hazard for people. Furthermore, some food producers inject hormones into domestic animals so as to make them grow more quickly and thus they can turn in more profit. As a result, people’s health has been seriously disturbed.

首先，我观察到许多食品生产商的利润驱动做非法的事情。他们的目标是赢得更多的钱在消费者的健康为代价。第二，农药的过度使用，导致食品质量下降。过量农药熊健康危害巨大。此外，一些食品生产商注入国内动物激素，使他们成长得更快，因此他们可以将更多的利润。因此，人们的健康受到了严重干扰。

All in all, food safety is such a great concern, and we all should do establish laws and implement them effectively to avoid producing toxic foods.

总之，食品安全是这样一个伟大的关注，我们都应该建立法律和执行有效的避免产生有毒的食物。

Not long ago. Sanlu milk powder incident once again draw the attention of food safety issues. Why food safety is always at risk? I think there are probably two reasons. For onr thing, the illegal business add a number of unsafe things into the food driven by the interests. For another thing, the countrys regulatory regime is inadequate, so that criminals can take advantage of the opportunity.

Food safety is very important. If you eat unsafe food, the consequences would be unthinkable. Therefore, we should take some measures to prevent unsafe food.

First of all, the government should strengthen supervision and improve the law to punish illegal food manufacturers. furthermore, when consumers buy food should depends on its production date and shelf-life. In short, to solve the food security issues need a long way to go, it needs the joint efforts of all sides.

With the development of science and technology, it is much more common for people to buy goods through different kinds of media than before. People can buy things such as computers and necklaces through TV, radio, the Internet, etc.

Shopping through media is welcomed by most people due to various reasons. From the perspective of consumers, it can save time for people who don’t have much spare time. For retailers, it can cut costs for those without much circulating funds. However, there are still some defects in shopping through media. First, compared with face-to-face deal, it seems less reliable and trustworthy. Second, people will lose the fun of bargaining.

In my view, although shopping via media brings great convenience to us, we still should be brings great convenience to us, we still should be

careful when we “go shopping” through media. We should check the information released by the media. Only in this way can we fully enjoy the convenience brought by media shopping without the concern of being cheated.
