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.

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.

Nowadays, online shopping is very popular for us to buy what we want.However, every coin has two sides.There are certain advantages and disadvantages of online shopping.

I think that advantages of online shopping are much more than its disadvantages.When shopping on the Internet and the global convergence,and is eager to grasp the fashion,the courage to try to have the family shopping, shopping quickly embark on a fantasy trip;Internet shopping from the conversation, payment, delivery, etc. entire transaction process, as long as it can on the Internet can easily get through the Internet, but also worried that with time;True contradictions, and do not want to go out, but there are things to buy.Not anxious to hurry up and open online shopping! Light points mouse goods immediately to the designated location;Hate shops face-to-face bargaining? Internet shopping to help you remove this problem.

Exchanges through the network can become friends for another shopping channel;Are in a foreign land, not peer-goers goods, not to buy things for people,and there is no need to feel sad for these, the owner of the Internet will be enthusiastic about your posts heart friends;Carefully selected, the results did not buy into, the owner was cold-shouldered by the experience you have had? Internet shopping you can see all goods Gegou,see the appropriate enthusiasm and the seller can talk to buy, do not face. Real happy shopping!

However, shopping on the Internet also has its disadvantages. The first disadvantage is that the consumers cant see the goods or try them on personally. Sometimes, the real goods may not be the same as what they have seen on the computer. The second disadvantage is that some shops on the Internet are not registered. They will never deliver anything to you after they get the money from you. Once cheated, you will find that you have nowhere to go to complain.There is always a trap online. If you are careless, it will bring you some trouble. You may find the color of the article is different from what you want, or the size is either too small or too big. If you want to be different, youd better not buy clothes online. Once you put on the clothes you bought online and go out, you will find many people wear the same clothes in the street.

Anyway, we should consider carefully which way to choose before we really buy so that we can buy the ideal goods.

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.

The Internet is indispensable in real life, it has become a part of peoples life. The Internet has both advantages and disadvantages, so let me say it.

In terms of interest, one: broaden your horizons. It also enriches the brain. 2: it is possible to communicate with each other, and one of the shortcomings of students is that they lack confidence and can overcome obstacles on the Internet. Third, it can promote the development of adolescent personality. Can reduce the pressure of homework. Talk to your friends about your worries. Four: can exercise writing pen, can have a sense of achievement. Five: can grasp the new education dynamic, the online test paper has everything, the student can choose freely. Teachers can also learn about new teaching methods.

There are three reasons for this. One: the Internet is just a virtual world. There are many pitfalls. For example, some unhealthy websites, high school students are not very good, only harm themselves. 2: the Internet is full of aggression, abuse and lying. We can say what we want, without any responsibility! Its immoral not to think about other peoples feelings at all. 3: according to the law, under the age of 18 years of age is not allowed to enter net bar!

Every new thing comes with a variety of worries, from films in the 1920s to the popular music video games. The focus of concern is violence, pornography, decadence and so on. There is a thin line between good and bad. Often "a miss is as good as a mile." The same goes for the Internet. The boundary between profits and profits is a disadvantage.

As a student, I am for myself on the Internet. We need not only to relieve the pressure of study, but also to replenish our food supply. Admittedly, most of us surf the Internet for better learning. In this sense, the net is the advantages and disadvantages.

The network is illusory, it is progress. The Internet is good for the bad, its up to you.

[网络社交危害英语作文

The advent of the Internet ushered in a new era of interpersonal communications and business operations. Undoubtedly, the Net are revolutionizing the daily lives of the people who have an access to it. The primary reason behind the Internet boom roots in its multifunction. It provides a vehicle for netizens to shop, search, publish blogs and browse WebPages.

A range of problems lurking behind the frenzy of Internet impressively stand out. A vast majority of Internet users mail boxes are saturated with junk mails, an issue which sparks strong criticism and generates the loss of corporate productivity. Its not alone. Porn websites lure a growing number of young peoples visits. False news via the e-mail, BBS and chat room increasingly poses a threat to the social prosperity and stability.

To crack down them, we should push for a more effectively tough law. We should join our forces to launch a nation-wide campaign, including imposing stiff penalties on spammers, shutting down or blocking the lewd sites and introducing a real-name registration system to curb fraudulent messages. We can fully believe that our combined efforts will reap rewards. A clean cyberspace will paint our lives more colorfully. An economically booming and technologically advanced global web will play a vital role in the national economic and cultural advancement.

The Internet becomes very popular in our life. It brings many advantages, but I think we primary students should keep far from the Internet.

Firstly, we should focus on our study, so we can’t spend too much time on the Internet. We can be easily addicted to it. Secondly, there is much harmful information on the Internet. They would do harm to us. Finally, surfing the Internet for too long is harmful to our eyesight.

Therefore, primary students should stay far from the Internet.

网络在我们的生活中很受欢迎，它带来了许多好处，但是我认为小学生应该远离网络。

首先，我们要潜心学习，所以我们不能花太多时间上网。我们很容易就会上瘾的。其次，网络上有很多有害信息，这些信息会对我们造成危害。最后，长时间上网会危害我们的视力。

因此，小学生应该远离网络。

[远离网络的英语作文示例

On the Internet, there are many unique languages that have become a feature of the Internet. What are these languages made of? Only people who surf the Internet often know about them, and online newcomers only listen to the "foreigner" conversation.

Some of these online languages are represented by several English letters, such as "GG" and "MM", which refer to men and women respectively. There are some homonym, such as "886" means "bye-bye", "94" means "yes", etc. Some use pictures to represent their mood or their expressions, such as ":" to express their happiness. There are other things, such as "table", which means "dont", "newbie" means a beginner... This is a strange thing.

The rise of online language is conducive to the convenience of information transmission. Because of the simplification of the language symbols, for those who typed unfamiliar, the benefits were not shallow.

However, young people dont understand the meaning of network language, is that they have the language barrier, and even make them unable to communicate, and has part of the network language is a vulgar language, such as "BT" refers to "abnormal" and so on, in one clean and pure heart, wipe off the black spot. Therefore, there are also bad aspects of online language.

Now is the Internet age, the emergence of network language and frequent use have become the trend, is inevitable. These convenient languages have become a bridge for people to communicate online. Therefore, we can only make the best of it: the relevant departments make relevant laws and regulations; Using computer technology, it is forbidden to "say" foul language; We should, of course, observe the conventions of Internet civilization.

I believe, as long as through peoples efforts, this rich characteristic language must return to have a pure sky!

Li Xiaohu spent too much time playing computer games and he fell behind others. As a good/close friend of his, I must do something to help him.

First, 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.

For this part, you are allowed 30 minutes to write a short essay based on the picture below.

You should start your essay with a brief account of the impact of the Internet on the way people communicate and then explain whether electronic communication can replace face-to-face contact. You should write at least 120 words but no more than 180 words.

“Dear Andy-How are youYour mother and I are fine .We both miss you and hope you are doing well. We look forward to seeing you again the next time your computer crashes and you come downstairs for something to eat, Love, Mom and Dad.”

范文: The modern technology has greatly altered the mode of

communication among people. With the help of the Internet, people can easily contact each other anytime anywhere. However, the side effect is that many people have become over-dependent on the Internet and neglected face-to-face communication.

As far as Im concerned, electronic communication cannot fully replace the direct contact among people. Although it seems to bring everyone together, it actually estranges people and decreases the effectiveness of communication. A typical example is that, traditionally, people working in the same office simply walk to others and talk. Today, however, co-workers tend to send e-mails or instant messages through the Internet even when they are sitting next to each other. As words can never convey the full message, it usually takes much more time and rounds of conversation than face-to-face communication, in which people can discuss more directly with less loss of information.

To conclude, the Internet enables more effective communication in some situations, but over-dependence on it actually pulls people apart.

应该禁止网络语言吗?

目前，网络语言，如“GG，MM，夏咪”，在青少年中已经流行起来。

关于网络语言有不同的看法。一些学生认为网络俚语生动，时尚，充满幽默和智慧。此外，它使上网聊天更快。

然而，另一些学生认为网络语言缺乏思想深度，过于简单。此外，它是很难理解和不被大多数人接受。这些话有时会使人迷惑，甚至造成误解。

每件事情都有两面性。在我看来，生活在信息时代，如果我们不知道互联网语言，我们似乎落后于时代。只要这些术语在适当的场合正确使用，就可以了。

Every coin has two sides , which is the same as surfing the Internet. On one hand , we benefit a lot from computers. For instance , many people are accustomed to going shopping on the Internet, which is a way to save time and money. What’s more, Internet makes it convenient for friends and relatives to communicate with each other. So people are more closed. Besides, we can go through the news all over the world through the Internet, which can broaden our eyes and assist us to learn more about the world.

On the other hand, with the popularity of computer games, more and more teenagers are addicted to virtual world , leading to a terrible grade and health. Moreover, plenty of unhealthy information emerges on the Internet, making a bad influence on teenagers.

In the 21st century, China has entered the homes of the television, but with the development of economy, the improvement of technology, the computer became the new favorite of the people in the 21st century.

The 21st century is a full of competitive information age, computer enables people to study and communication become more rich and colorful, make knowledge more convenient.

Once the teacher asked me to look up the information a historical figure, I read many books, but didnt find the information to, really worried. But later the Internet, not for a while, then find the information. This information can be found, thanks to the Internet!

The last time I saw on TV, there is a village of dozens of rural development resources, planting several acres of green vegetables, but no one has to order out. A learning computer, help them to think of a way to surf the Internet to find customers. All of a sudden, a lot of clients under the order on the Internet. A few days later, the piles of vegetables are sold out. These vegetables are placed in the fate of the rot in the home was changed by a small computer, what a miracle!

在二十一世纪的中国，电视机已迈入了千家万户，但是随着经济的发展，技术的提高，电脑在二十一世纪成了人们的新宠儿。

二十一世纪是一个充满着竞争的信息时代，电脑使人们的学习和信息交流变得更加得丰富多彩，使知识的获得更加便捷。

有一次老师让我查找一位历史人物的资料，我翻阅了许多的书籍，但还是没有找到所要的资料，真是心急如焚。可是后来上网一查，不出一会，便找到了资料。这次能找到资料，真是多亏了电脑网络呀!

我上一次在电视上看到，有一个村的几十户农民开发资源，种植了好几亩的绿色蔬菜，但是一直没有人来订购出去。一个学电脑的人帮助他们想了个办法，上网找客户。一下子，许多客户都在网上下了定单。没过几天，便把这成堆的蔬菜销售一空。这些蔬菜被放在家中腐烂的命运，被一台小小的电脑所改变了，这是多么的神奇呀!

Therapid development of the Internet in China has brought us great convenience in our daily life and work. We can send e-mail or even talk to our friends or parents via the Net. We can get whatever we need on line. So some people think we can learn all we need on the Internet.

But I do not agree with this opinion, because sometimes I find many students play the computer games, or talk about love affairs through the Net, which makes them fall behind others in study. In my opinion, the Internet should be a good tool for us to communicate with others rather than an invention for fun. What’s more, it will do harm to us instead of good if we spend too much time looking at a computer.

In summary, it would be very difficult to learn if you dont have a teacher. Also you should pay attention to the importance of working together in a class.So I hope every student values this great invention and makes good use of it.

Dear Mike，

I’m sorry to know that you feel confused about making friends on line at your new class.

I have ever read a story, which made me greatly shocked. Such a kind-hearted girl was cheated and laughed at by the cheat. She wanted to help the boy，but what the boy said was a trap.

In my opinion, making friends on line is a good wayto communicate with people from all over the world. However, every coin has two sides. When people try to make friends on line， they have to be very careful and cautious. Before meeting an on-line friend, they have to ensure that all the information concerning him or her is true.

To solve the problems concerning making friends on line, I think, the government should take strong measures to punish those who cheat people on line. As for those Internet users，they should be cautious when making friends on line.

I hope you can adapt to the new school life as soon as possible.

Social Networking’s Influence on College Students

Social networking has gained huge worldwide popularity in recent years, especially among college students. In China, college student is the main force of social networking, 97.7% of which are fond of instant messaging and 80.7% prefer social networking sites like micro-blog and Q-zone (China Internet Network Information Center, 2013). Moreover, Michigan State University Original Study also finds that compared with Chinese students, American students are more tied to social media (2013). Therefore, nowadays there is a heated debate about advantages and disadvantages about social networking’s influence on college students.

Obviously, there are a number of positive features on social networking. It provides a convenient access to consolidate the relationship with people they know, make friends with strangers without restrictions of space and share happiness and sorrow. What’s more, social networking also has educational functions including reducing college drop-out rates, motivating students to work as a team, sending information about assignments, reminding students about deadline and stimulating students to help each other. (BBC News, 2009). There is no doubt that social networking plays a significant role in eiching students’ college lives.

However, every coin has two sides. There are also many disadvantages on the influence of social networking, among which, “soft addiction” is the most serious problem, distracting students from study. Because of lack of self-restriction, many students would waste plenty of time to search the social networking sites unconsciously, followed by a strong tendency to blame themselves (Li, 2013). This kind of “soft addiction” and distraction was also confirmed by Zhang (2011) who conducted a survey by questionare of 500 Chinese college students from different schools and found that 33% students could not bear one-week life without social networking and 77% students could not help themselves accessing social networking site during classes. Furthermore, a social experiment was performed by Harrisburg University (Pilkington, 2010) to figure out the effect after initiating blackout of all social networking sites. It turned out that some students became more concentrated on

the tutor and making notes instead of having instant messaging running in classes.

As far as I’m concerned, the disadvantages far outweigh the advantages, especially in China, where social networking is used for communication and entertainment and seldom plays the educational role (Li, 2011). The priority of a college student is to study hard instead of being addicted to social networking. Therefore, it is imperative for them to realize their “soft addiction” to social networking and correct their behavior.

从古时货郎挑着担子走遍大街小巷，吆喝叫卖，到之前琳琅满目、一应俱全的超市，到电脑上的淘宝，再到现在随处可见的二维码。人们的购物方式有了翻天覆地的改变。随着互联网、智能工具的产生发展以及社会分工的细化，我们的生活方式都逐渐被碎片化了，从一类信息跳到另一类信息成立我们的常态。其中，购物的变化极为明显。

碎片化购物是空间、时间的解放。所谓解放，就是缩短了人们的购物路径。不必在节假日中，还挤入熙熙攘攘的人群，抢着促销商品，你可以舒服地躺在床上，悠闲地在手机上浏览，货比三家，看看评论，领张优惠券，最终选出你心仪的商品。不必因繁忙，而担忧没时间买柴米油盐酱醋，通过网络，你可以乘公交车、坐地铁时就下份订单。甚至可以不必带钱包，只需通过电子支付软件扫一扫，就可以购买，不用拿着零钱，也不必担心商家不诚信。

碎片化购物更有选择性。随着网络的发展和信息的整合，有些购物软件可以根据用户的个人喜好、商品性质，挑选出它认为适合你的商品，使购物更方便。相比传统购物，它已经提前帮你筛了一遍，缩小了范围。同时也让你感到一股温暖，同时也感叹着科技的发达。

碎片化购物很好地利用了人与人的关系。你可以将要买的商品链接分享给身边需要的朋友，一起参与团购、或让大家帮你出出主意、进行决策。这样碎片化的购物让这件事不再是一个人的事，而是大家都能参与进来的一个活动，让这件事变得更有趣，更生活化。

尽管碎片化购物给我们的生活带来了很多便利之处，但也有一些缺点。你可能不能在网上准确地体会到商品的一些性质，缺少真实感，比如买衣服可能不确定这衣服的尺码、手感。你也可能因为商家做的一些活动而忽视了这些商品在日常生活中的使用度，而买了许多不需要、没必要的杂物。这些问题说大不大，说小也不小。我相信在这个如马车般不断前行的世界，总有人会解决这些问题。

碎片化经历了不断的蜕变，使我们的生活变得多姿多彩起来。他有利有弊，会给我们带来便利，也同时会使我们的思维模式变得表面化，无法深入思考。碎片化的生活究竟会怎样，会将人类生活改变到什么程度，还终是未知数。
