Besides, Internet has provided a major opportunity to buy and sell merchandise (商品). What is more, people may get medical help or even vote on Internet. Its advantages seem countless.

Behind all this glowing talk, however, are some problems. Internet makes people passive by stop.

One possible version：

Nowadays, with the development of the Internet, there is a kind of language called Web language. Some people even speak Chinese mixed with English letters. Our class have a discussion about it.

40 percent of the students think it is kind of ridiculous. In their opinions, it is useless helping people communicate or learn English. Besides, it will ruin the Chinese language. However, the others, 60 percent of our class, are fond of the Web language. They think it is helpful in expressing themselves. What’s more, it may make the language more interesting.

In my opinion, it’s not a good habit to use the Web language. It may be popular as some people think, but you may also make yourself misunderstood.

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.

当今的社会已经迈入了一个高科技、多信息交流的时代，网络也已经是不可缺少的了。有些人利用网络去学习，有些人利用网络去娱乐，最可恶的是，有些人利用网络发布一些有害于社会、国家经济、家庭以及人的生命的不良信息。

例如：在前几年发生过一起网络偷盗事件，就是几名电脑高手利用网络，向银行的电脑防护系统进行攻击，当防护系统被破坏掉之后，他们就钻进电脑里去，更改了他们事先在银行里的帐户的存款。

从这件事之后，人们开始对网络做出了许许多多的措施，但是，还是抵挡不住犯罪分子的进攻手法。

身边也有许许多多被网络吞噬的人。

比如，现在某些网吧老板，经不住金钱的诱惑，让一些青少年进入。这些青少年一旦进去之后，就可能被网络里的形形色色所吸引。他们从网络里面得到了许多现实生活里不能得到的东西。尤其是，他们被老师或家长批评、打骂之后，心理的怨恨、委屈没法向别人倾诉、发泄时，网络就是他们最好的发泄对象。他们就这样，一天一天的堕落下去，仿佛掉进了一个永远不能自拔的沼泽里去了。

如今，人们就网络对我们生活的影响展开了广泛的讨论，利弊分析英文。确实，网络就是一个利弊兼有的东西。

总的来说，大家普遍认为网络有如下两个主要优势。第一，网络让我们便捷地得到我们在生活、学习和娱乐中所需要的一些必要的信息和素材。第二，网络大大提高了我们日常生活的效率，比如购物和交流，为我们节省了很多的时间，精力和金钱。

当然，正如俗话说得好，每一个事物都有两面，网络也不例外。网络的弊端也是非常明显的。首先，我们从网络使用中享受到的舒服和方便让我们变得更加懒惰，进而对网络产生了太多的依赖。另外，网络也滋生了社会中的骗子，给他们提供了良好的生存土壤。

总之，我们应该尽力发挥网络的“利”，同时尽量去减少网络的“弊”。这样一来，我们就能更好地利用网络。

导语：吸烟有害健康，我们一个远离它，下面是yuwenmi小编为大家整理的英语作文，欢迎阅读与借鉴，谢谢!

A survey about smokers in a middle school tells that although 90% of all students never smoke, 3% of them often smoke and 7% sometimes do. In other words, 10% of the students smoke. That s terrible.

As we know, smoking is harmful to our health. Every year, thousands of people lose their lives because of it. Smoking not only does harm to your health, but also wastes money. Because, a fire may be caused by cigarette ends. It s a pity to learn that one ends in death by smoking.

In all, smoking is so dangerous that we should keep away from it.

参考翻译

一项关于中学生吸烟的调查显示，尽管90%的学生从不吸烟，其中有3%的人经常吸烟，有时有7%的人吸烟。也就是说，10%的学生吸烟。那太可怕了。

众所周知，吸烟有害健康。每年都有成千上万的人因此而失去生命。吸烟不仅有害健康，而且浪费金钱。因为，火灾可能是由烟头引起的。得知一个人死于吸烟是令人遗憾的。

总之，吸烟是如此危险，我们应该远离它。

网络的发展，既给我们带来了便利，也增加了犯罪的方式。下面是小编给大家整理的关于网络利弊英语小作文，供大家参阅! 关于网络利弊英语小作文

Internet brings us a both advantages and disadvantages. The advantages are as the following. Firstly, we can communicate with our friends more rapidly and quickly. Secondly, Internet brings us fun. For example, many websites open chatrooms where we can talk with different people and make new friends. Finally, many businessmen are taking so|called E|business seriously on the net.

The Internet also has its disadvantages, just as a coin has two sides. In the first place, some people may linger too long on the net while neglecting their work or study. In the second place, some columns on the net may have a negative influence on the youth electronic commerce.

In my opinion, Internet becomes an integral part of our lives, but it is certainly not everything. Living in the 21st century, we need to make good use of the new tool-Internet, but it is just a tool, not life itself. We should not depend on it too much, nor should we ignore it deliberately. 关于网络利弊英语小作文

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.

Only we combine the real life and computers can we use it reasonably.

As we all know, the 21st century of the Internet. With the development of the Internet, more and more people begin to use it to enjoy themselves or do something special. However, every coin has two sides , the Internet also has its own advantages and disadvantages.

Our life has a great change since we use the Internet. We benefit a lot from the Internet. As for me, I am accustomed to going shopping on the Internet, which is a good way to save my time and money. Many people do the same as me. What’s more, the Internet makes it convenient for us to make friends and get people closed . We can also go through the news all over the world.

The Internet has dramatically altered our lives over the past few decades. Although some of these changes have been negative, the overall effect of this technology has been positive. What are your opinions on this?

The Internet has brought significant changes to our lives in recent years. However, there remains some disagreement as to whether the overall effect of this technology has been positive or negative. While there are certainly valid arguments to the contrary, I personally believe that the benefits of the Internet far outweigh its drawbacks and these benefits are twofold.

First of all, it is an indisputable fact that the Internet has revolutionized the way we communicate. Despite the risk of social isolation-a problem occasionally seen in people who spend too much time at their computer terminal rather than relating to people in the real.

First of all, Internet brings much convenience and a colorful world for people.

随着高新技术的发展，互联网越来越受欢迎。无论是儿童还是老年人都知道如何使用因特网。互联网的出现给人们带来很多好处，而人们也发现带来了危害。

首先，网络给人们带来了很多便利和丰富多彩的世界。通过互联网人们可以在家里买所有的东西，了解各种信息，与来自世界各地的人交友等等。没有互联网，人们不可能享受到那些好处。此外，因为有很多人在网上购物，对快递员的需求也日益增加。这给许多人创造了就业机会。然而，互联网也给人们带来不利。由于互联网的美妙，很多人都沉迷于它。由于沉迷于玩电脑游戏而荒废学业或工作。再者，因为人们可以在网上接触到各种各样的信息，他们很容易看到一些不良的信息，这对他们的成长是有害的。

总之，任何事物都有两面性。互联网也有优点和缺点。但就我而言，如果人们正确使用互联网的话，它的优点优于缺点。

考研英语作文：网络的利与弊(Advantages and Disadvantages of the Internet)

一个女孩正在因一个问题感到困惑，“10牛的水是否产生10牛的浮力?”。于是她上网求助于网友，网友的答案更是五花八门，说对说错的都有。女孩更加困惑。由此可见，这件事反应了这样一个现实：网络文化有利也有弊。因此本文可以这样设计：

第一段：描述事情发展;第二段：网络的利 举例，网络的弊 举例;第三段：提出建议措施——取其精华，去其糟粕。

思路拓展

所有利弊型的文章，均可按照本范文提供的思路进行论述。例如，城市化的利与弊。大学扩招的利与弊等。

参考范文

a girl is asking a question online. Answers from different netizens differ so greatly that the girl is very confused about whom she should follow。 It is obvious that it is becoming a fashion for people to ask questions online when confronting a dilemma.

The implication implicit in the matte can be elaborated as follows①. On the one hand， the Internet has provided us with great convenience. For example， we can get knowledge about nearly all aspects on the Internet with only several keyboard commands and a few clicks of the mouse through search engines such as Baidu and so on. On the other hand， with an explosive amount of information on the Internet②， it can be difficult to tell good information from bad③。 For example， teenagers and adolescents may mistake the bad information online as good， the result of which can be rather devastating. Some dirty information on the net may exert negative impacts on people.

In conclusion， on the one hand， it is important for us to take full advantage of Internet to enhance our efficiency and save our time. On the other hand， effective steps should be taken to educate people to avoid and elude inappropriate and even wrong data online so as not to be misguided. Only in this way can the net better serve for our life， study and work④。

一个女孩正在网上问一个问题，来自于网友的答案差异太大了，以至于女孩很困惑到底该听谁的。很明显，人们面临困境的时候上网提问的现象已经成为一种时尚。

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.

[英语作文正确使用网络

“海内存知己，天涯若比邻”。都用这句话形容互联网的神奇，可是网络也不是“十全十美”。瞧，各种鬼故事在网络间“神出鬼没”，这不，我也上了当。

我很喜欢上网，因为我觉得网络仿佛就是一个无穷无尽的知识海洋，而我在其中自由地穿梭着。有一天，我跟往常一样在网络间漫无目的的乱浏览，无意间点中了一个名为《鬼故事》的贴子，我紧接着向下滑动，一张张既恐怖又恶心的图片浮现在我眼前，我直接吓得把手机扔在了地上，我发了半晌的呆，才忐忑不安的捡起手机，直接把网页给关了。

晚上，我出门去打篮球，在回来家路上看见了一个穿着红色连衣裙的女子，一头长发披散在脑后，头低着，使我想起了那张令我难忘的“黑与红”的图片，我仿佛觉得那个“女鬼”正盯着我，害得我起了一身鸡皮疙瘩，连忙急匆匆地跑进了小区。

睡觉了，我躺在床上，灯光暗了下来，突然，那恐怖的图象如同复印似的，在我脑中重复的出现，四周突然响起了鬼异的怪声，电灯忽闪忽闪地，吓得我几乎是屏息凝视，被子都要盖过头顶了，那恐怖地声音越来越响，在我心间回荡着，久久挥之不去，我最后还是忍不住害怕伸手就向开关按键按去，灯亮了，我看见周围景物并没有异常，才又昏睡了过去，连关灯也都忘在了脑后。

网络的危害可真大啊，一个不小心就上当了，就像我。

The Internet is one of the most discoveries of the twentieth century . More and more people or using the Internet . They usually use internet to send E-mails and play games . In many ways it has changed or will change our way of life .

Firstly , it will change our way of communication . We will exchange information with others on Internet instead of letters or telephones , which is much cheaper and faster and contains much more information .

Secondly , we can get information very quickly . Actually we can get information from all over the world in just a few minutes . It saves a lot of time .

Thirdly , we can make many friends through the internet . We can get in touch with people faraway , even from foreign conrtres . They can tell us a lot about their own counties .

Fourthly , we can buy things through Internet without going out and enjoy ourselves with some films and songs at home .

Furthermore , we can have on-line course-course in which students follow the Internet . We can work at home and in our own time . This enables us to use our time more flexibly .

In a word , Internet will change our life in many ways and it will be very helpful it we use the Internet wisely .

网络是一种很好的信息交流工具，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!

电脑对人体的五大危害：

一是对身体健康的直接影响：电脑显示器伴有辐射与电磁波，长期使用会伤害人们的眼睛，诱发一些眼病，如青光眼等;长期击键会对手指和上肢不利;操作电脑时，体形和全身难得有变化，高速、单一、重复的操作，持久的强迫体位，容易导致肌肉骨骼系统的疾患。计算机操作时所累及的主要部位有腰、颈、肩、肘、腕部等。

二是电脑微波对身体的危害：电脑的低能量的X射线和低频电磁辐射，容易引起人们中枢神经失调。英国一项办公室电磁波研究证实，电脑屏幕发出的低频辐射与磁场，会导致719种病症，包括眼睛痒、颈背痛、短暂失去记忆、暴躁及抑郁等。对女性还易造成生殖机能及胚胎发育异常，出现痛经、经期延长等症状，少数妇女还发生早产或流产，孕妇每周使用20小时以上电脑，其流产发生率增加80%以上，同时，还能导致胎儿畸形。

三是增加精神和心理压力：操作电脑过程中注意力高度集中，眼、手指快速频繁运动，使生理、心理过度重负，从而产生睡眠多梦、神经衰弱、头部酸胀、机体免疫力下降，甚至会诱发一些精神方面的疾病。这种人易丧失自信，内心时常紧张、烦躁、焦虑不安，最终导致身心疲惫。

四是导致网络综合征：长时间无节制地花费大量时间和精力在互联网上持续聊天、浏览，会导致各种行为异常、心理障碍、人格障碍、交感神经功能部分失调，严重者发展成为网络综合征，该病症的典型表现为：情绪低落、兴趣丧失、睡眠障碍、生物钟紊乱、食欲下降和体重减轻、精力不足、精神运动性迟缓和激动、自我评价降低、思维迟缓、不愿意参加社会活动、很少关心他人、饮酒和滥用药物等。

五是电脑散发的气体危害呼吸系统：电脑、激光打印机等设备会释放有害人体健康的臭氧，不仅有毒，而且可造成某些人呼吸困难，对于那些哮喘病和过敏症患者来说，情况就更为严重了。

另外，较长时间呆在臭氧气体浓度较高的地方，还会导致肺部发生病变。

今天已经是放假的第六天了。天气晴朗，不过下午还下了一场“降温雨”。下午我上了qq和我的好朋友陈建涛、关孝熙聊天，我对小陈说;“今天我们一起玩CF好吗?”“我听说孝熙也在玩。”小陈说：“好啊!他一玩我们就一起打他。”孝熙听了就说：“好你个小子竟然夹攻，我和你拼命。”小陈和我都比孝熙的级高，我的职位是中士、小陈职位是上士而新来的孝熙职位是二等兵。

下午4：00到了，我和小陈、孝熙一块玩游戏。我们玩生化幽灵。我拿着阻击枪瞄准好孝熙，嘣的一声他扣血了。然后我就捡到一把机枪“汤姆逊冲锋枪”哇威力无比，不一会儿就把孝熙给杀得半血，我又捡了补给“M60-A”机枪哇!这一支更爽，不一会儿吧4000多血的生化给杀了。最后我们玩了歼灭模式，拿着散弹枪冲向敌人的营地杀了一个片甲不流，我居然作了ACE。其实，在放假期间有时放松一下也是可以的。有时和朋友聊聊天也很开心的

My views on campus security

Our university have a bad campus security problem I think.There is so much thieve in our campus,one of my schoolmate had already been stolen three bicycle,for more convenience in campus,he cannot help but bought anyother second hand bicycle.they go to the emplacement bridge for second hand bicycle,and the crabman there find more bikes for selling,and then people who lost the bicycle go there for another,then they stolen more, then come into being avicious circle that will never be end. From Joozone.com.And the dormitory security isn’t enough for more and more student found that they have been stolen valuables when they come back dormitory after class. For does the campus sexurity well,I think it should give more guards around student’s dormitories when students are studying.And I think it also should make another more firmly door for dormitory guard.

电脑对于我们来说并不陌生，它使我们的生活更充实了，它使我们的工作、学习更有效了，它使世界人民的距离更近了，它深受很多人的喜爱，但它也给我们家带来了麻烦。

我哥哥他以前一直是个乖巧，好学的孩子，整天都捧着一本书读，他妈妈叫他干活，他二话不说，就按说的去做。他一直是我学习的好榜样。可是自从有了电脑，他逐渐迷上了网络游戏，学习一天不如一天。

你瞧，他又在玩c.f了

“啪啪，看你还不死，快死。”哥哥说。

“哥哥，我求你了，不要再玩游戏了，游戏有什么好处，他是你学习下降的罪魁祸首。”

还没等我说完，哥哥就说：“小屁孩你懂什么呀，滚!”哥哥的每一个字都想针一样扎进了我心里。

“是啊，我是小屁孩。但是，我知道稍微玩一下网络游戏，可以舒精解疲，一旦玩多了，不但会影响我们的视力、智力，甚至会使我们做错事、犯罪。你看，这一张张奖状都是你以前得来的，可自从你迷上了网络游戏，你的成绩直线下降，奖状与你绝缘了。你有没想过我们心里会怎么想。你看，你爸爸、你妈妈愁得白头发都有了。”说到这里，我看了他一下，可他眼睛直盯着屏幕，哪里听得进去。

我知道网络游戏，已经让无数老师、家长望而生畏。所以我们要控制玩游戏的时间，适度上网，健康上网。

以下是《九年级英语作文:我和哥哥的历险记》翻译。

It was sunny that day. Our parents were out, so there were only my brother and me at home. We were bored. So we decided to go boating. We played happily. But when we went to the middle of the river, the weather changed. It rained suddenly. We didn t bring umbrella and our boat was bamboo raft. As the rain was more and heavier, we were afraid to sink in the river. We tried our best to make our boat in shore. But our bamboo raft had more water on it. I was afraid to die. My brother was also very anxious. At that time, my mother came and she pulled us back to the ground. It was thrilling.

那是一个晴天。我们的父母都出去了，所以只有我和哥哥在家。我们很无聊。所以我们决定去划船。我们玩的很开心。但当我们走到河中央时，天气变了。突然下起雨来。我们没带伞，而且我们的船还竹排。由于雨越来越大，我们担心会沉到河里去。我们尽力使我们的船靠岸。但是竹筏上的水越来越多。我害怕死了。我哥哥也很着急。那时，我妈妈来了来了，她把我们拉回到地面。真的惊心动魄啊。

Everybody watches the winter haze weather, the fog haze harm is bigger, there are several city already in it, so we should strengthen the environmental management efforts, no longer let haze weather.

Must have a lot of people know the cause of the haze, fog, fog and haze, of course, is made of, fog is the main cause of a large number of small water droplets or ice crystals suspended in the ground the air system, composed of aerosols is a product of condensed water in the air near the ground layer. Fog is mainly will reduce visibility, can cause traffic hidden trouble, but not harm to people.

Haze is made up of the dust in the air, harmful material such as sulfuric acid, nitric acid, it can make the atmospheric turbidity, blurry vision and leads to reduced visibility, and can cause great harm to human body. So fog and haze two brothers together, this irrelevant to unprecedented damage caused by the atmosphere, some citys air quality has come to the point where moderate pollution, some cities has reached high levels of pollution, more terrible.

The dangers of smog is quite large, it will for highway, railway, aviation, power supply system, affect crop growth. Also easy to cause the spread of infectious diseases and a variety of diseases. Harm to peoples health. And can lead to air pollutants is not easy to spread, enhanced the toxicity of harmful substances, serious, may also cause smog. And can cause great harm to people, especially a great influence on the respiratory system. It is reported that this winter respiratory disease increased than last winter % % 30-40. This is what a staggering, worthy of our thought. So the prevention and treatment of haze weather is urgently needed.

Our precautions should be in place, in haze weather, we should stop morning exercise and outdoor activities. This just isnt good enough, I think this is the main reason of the bad weather in automobile exhaust emissions and industrial emissions, so the country should policy instructions as soon as possible to manage and control the harmful gas emissions, more tree and grass planting, purify our environment. I think, if everyone is mobilized, haze weather should flew away.

In a word, I hope you can take action, a variety of grass flowers, how to protect the environment, for our future generations to build a green, natural environment.

这个冬天雾霾天气备受大家的关注，雾霾危害较大，有好几个城市已经中了它的招，所以我们应该增强环境管理的力度，不再让雾霾天气横行。

雾霾的成因想必有不少人知道，雾霾吗，当然是由雾和霾组成的，雾的主要成因是大量悬浮在地面空气中的微小水滴或冰晶组成的气溶胶系统，是近地面层空气中水凝结的产物。雾主要会使能见度降低，会造成交通隐患，但对人的危害不大。

霾是由空气中的灰尘、硫酸、硝酸等有害物质组成，它会使大气浑浊，视野模糊并导致能见度降低，并且会对人体造成较大的伤害。这样一来雾和霾两个本不相干的兄弟聚到了一起，对大气造成空前的破坏，有些城市的空气质量已经到了中度污染的地步，更有些城市已经达到了重度污染，非常可怕。

雾霾的危害相当大，它会对公路、铁路、航空、供电系统、农作物生长造成影响。还易导致传染病扩散和多种疾病发生。危害人的健康。并且会导致空气中污染物不易扩散，增强有害物质的毒性，严重的，还可能会导致毒雾发生。并且会对人造成巨大伤害，特别是对呼吸系统影响很大。有报道称，这个冬天呼吸系统发病的人比上个冬天增加了%30---%40。这是一个多么惊人的数字，值得我们深思。所以防治雾霾天气刻不容缓。

我们的防范措施应该到位，在雾霾天气时，我们应该停止晨练和户外运动。只是这样还不够，我认为造成这种恶劣天气的主要原因是汽车尾气的排放和工业生产废气的排放，所以国家应该尽快下达政策来管理和控制有害气体的排放，多植树种草，净化我们的环境。我想，如果大家都动员起来，雾霾天气就应该灰溜溜的逃跑了吧。

总之，我希望大家可以行动起来，多种草种花，多保护环境，为我们的子孙后代营造一个绿色，天然的环境。

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.
