网络公开课的英语作文【精彩20篇】

With the development of the Internet, the net bar plays an important role in people s life. More and more people, especially students, like to go to net bars.They are absorbed in playing video games, making bad friends and having a chat with Meimei on the net in the bar. Some students often go on playing late into the night in the net bar. As a result, not only does it do harm to their health but also produces a bad effect on their studies.

Now a lot of net bars have been shut down in Beijing. But some students go by bus to the net bars at suburbs to play. Fortunately, more and more parents and schools have realized it. Recently, more than six thousand students guaranteed that they would be far away from net bars in Jinzhou city, Liaoning Province. It is quite necessary for the students to get rid of the bad habit. ​

Nowadays, there is a widespread debate about the influence of the Internet upon peopleslife. Undoubtedly, there are both advantages and disadvantages in the Internet.

Generally speaking, it is widely believed there are two major positive aspects of the Internet asfollows. Firstly, the Internet has provided us with easy access to the necessary information andmaterials we want for living, learning and entertament. And secondly, the Internet haspromoted greatly the efficiency of our daily affairs such as shopping and communicating, saving us a lot of time, energy and money.

However, as a popular saying goes, every coin has two sides, and the Internet is noexception. The negative aspects of the Internet are also quite apparent. To begin with, thecomfort and convenience we get from the Internet is gradually making us lazy and dependtoo much on it. In addition, the Internet is a fertile soil where many dishonest people areborn and grow.

To sum up, we should try to bring the advantages of the Internet into full play, and reduce thedisadvantages to the minimum at the same time. In that case, We will definitely make a betteruse of the Internet .

消防，这个词语对大家来说有些陌生，却又曾有所听闻。的确，在人们的生活中，消防安全常识并不是很普及，人们并没有过多地了解消防的安全措施，导致每当灾难发生时，才会真正认识到消防知识的重要性。

就在几年前，高砂镇防火办接到农民报告，端溪村发生了森林火灾，由于风大，大火蔓延迅速，火苗飞过沙溪河，使对岸起火，并越过高速公路，向不同方向蔓延，形成大连山隧道、高砂镇龙江村、青州镇涌溪村多个火点。受火灾影响，当地部分高速公路、铁路和电力一度受到较大的影响。而这场灾难的原因，是因为农民烧树肥地，而触发森林大火。一个小举动，就造成了这么严重的后果，然而，如果当时那些农民对消防安全知识有所了解，那么，也许这场悲剧就不会发生。

“火善用之则为福，不善用之则为祸”确实，火能给我们带来好处，但如果不好好利用，那么，带来的将是灭顶之灾。所以，“祸在一瞬，防在一时”，我们应该提高消防安全意识，了解一些消防安全措施，这样，当灾难来临时，我们就能镇定、机智地应付。

我听过一个故事：当时，一个七岁的小女孩在做作业，突然闻到煤气的味道。当她检查后发现她的爸爸妈妈已经在浴室里被煤气熏晕了。就在火烧眉毛之际，她果断地打开窗户通风，并拨打了报警电话，阻止了一场灾难的发生，救了自己的父母。想一下，如果小女孩根本不了解消防知识，盲目地做出举动，例如开关电灯，就可能引发出一场火灾，造成一场悲剧，家破人亡。从中可看出，了解消防知识是多么的重要，不仅能为己所用，还能求助他人，将一场噩梦的开始转变成可喜的结局。

而当火灾真正发生时，我们首先要做的就是拨打火警电话，受到火势威胁时，要当机立断地披上浸湿的衣物、棉被向安全出口冲去，不能贪恋财物，不可乘坐电梯，若是逃生路线被大火封锁时，要立即退回室内，用手电筒、挥舞衣物、呼叫等方式向窗外发送求救信号、等待救援，但千万不可盲目跳楼，可利用疏散楼梯、阳台、落水管等逃生自救，也可以用绳子或把床单、被套撕成条状连成绳索，紧拴在窗框、暖气管、铁栏杆等固定物上，用毛巾、布条保护手心，顺绳滑下，脱离险境。

其实，火灾大多数是在不经意间发生的，往往是一个烟头，一点儿小伙星，也能造成一场大火，“疏忽一时酿火灾，痛苦一生追悔迟”，所以说，我们要防范于这种一时的疏忽，勿造成一生的痛苦!

消防安全须重视，了解措施避火灾!

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。

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.

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.

应该禁止网络语言吗?

目前，网络俚语，如“GG，MM，夏咪”，在青少年中已经流行起来。

关于网络俚语有不同的看法。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俚语缺乏思想深度，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俚语，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。

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 I‘ll 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， I’ll ask both his parents and our teachers to help him， too。 If I try these， I‘m sure he will make great progress soon。

人事有代谢，往来成古今，江山留胜迹，我辈复登临。踏寻先辈的履印，消防安全也是我们一直追寻的主题。而我对此却不以为然，对消费安全也并不重视。但那一天，我却明白了消防安全的重要性。

那天我漫步于灯火阑珊的街道，天上乌云遮住了半边太阳，望着四周人群，络绎不绝;嗅着街旁丁香，芬芳四溢;听着树上小鸟，余音缭绕。陶醉于周末闲暇之中，一切都是那么美好。但一声尖叫，打破了这一份宁静。

“着火啦!救命啊!”一声尖叫传来，街上的行人听到了顿时惊恐万分，人们抱着头，跌跌撞撞地朝南边涌去。

就这样，一场关乎生死的追逐战开始了。

“红流”席卷了大半个街道，它如同魔鬼一般，吞噬着街道上的一切。

一段时间过去了，人们早已身心疲惫，豆大的汗珠从额头上滚落下来，人们你拥我挤。忽然有一位妇女跌倒了，她坐在地上，睁大眼睛，张大嘴巴，恐惧地盯着那个恶魔，已经对生存不抱希望。

但命运并没有抛弃她——消防员来了。他们站在火堆前井然有地指挥着人们，救起妇女后，准备开始控制火情。但却发现消防栓被无良档主封死了，并在周围摆满了花花草草。顿时，那几位消防员也束手无策，跟着人流继续奔跑了起来。

一阵大风掠过，“红流”加速开始追赶，“红流”马上要追上人流，人们的心都是紧绷的，我们大口大口喘着粗气，拼命地向前跑去。不可思议的事情发生了——天空中下起了倾盆大雨!这场雨控制住了这股“红流”，人们心里的那块石头也落了下来。

次日，我再次路过这条被火烧得狼狈不堪的街道，偶然听到了两个男人的对话。

“这怎么了?”一个男人问道。

“被大火烧了，死了十几个人，听说原因是因为有一家店里煤气没有关紧发生了爆炸。”

“活该!谁叫他们不注意消防安全呢?”

听到这里，我再也忍受不住，跪在地上痛哭起来，顿时，我好像懂得了什么道理……

消防安全伴我行，那次惊心动魄的追逐，我彻底懂得了消防安全的重要性。

Internet may have been one of the most influential but disputable existences in the world, ever since its first appearance in the late 1960s. Internet has accelerated the world’s development with an incredible speed; nevertheless, it has brought this world many burdens. Nowadays, nobody can imagine what the world will be without this double-edged sword.

In my opinion, the most prominent contribution Internet has made to the world is, to offer every one of us such a convenient access to the vast outside information-based society. With appropriate use of Internet, the distances between people of different nations and countries are shortened. As long as you have a computer with network, you can easily get all kinds of information you need or the latest news from Internet, moreover, you can contact private friends or business companions all at your disposal via Internet. A coin has its two sides, and Internet is no exception to a coin. While bringing the world great convenience, Internet also gives out many negative effects, such as some porn websites, addiction in online games and so on. Especially the young people, with less self-restraint, if misled, will be likely to indulge themselves in the harmful parts of Internet. As a result, many of them lost their interests in study and eventually become, in a manner, uneducated people. Such examples are not rare in reports.

Given the above arguments, I honestly hope we can make good and full use of Internet, this marvelous fruitful creation of mankind. Although it’s a double-edged sword, with correct selection and decision, Internet has contributed a lot to the whole society and it will go on in this way.

[我对网络的看法英语作文

In recent years, the Internet has been gaining its popularity at an amazing rate. Some people suggest that the Internet brings us a lot of benefits. But on the other hand, there are also many people who strongly advocate that its drawbacks should not be ignored.

Those who favor that the Internet has many advantages give their reasons as follows. In the first place, the Internet brings us great convenience and efficiency.In the second place, we can make friends with people from all parts of the world. Furthermore, the Internet accelerates the flow of information and spreads education to all corners of the globe.

However, For one thing, it can easily lead to psychological problems.For another, there is a sharp rise in the number of cyber crimes.

For my part, I completely agree with the latter view that the Internet has more disadvantages than advantages.

With the popularity of Internet, cyber crimes are a serious problem, people’s computer will be easily attacked, because cyber criminals are everywhere on the Internet. The personal computer is no longer safe completely, we must take the measures to deal with cyber criminals. The government should reinforce the law to give heavy punishment to the cyber criminals. The people who are talented in computer technology should be trained to improve the computer defense system and more effective firewalls should be built up. What’s more, people should pay attention to not click the illegal websites. All these measures are working to protect the security of the Internet, there is still a long way to go.

随着网络的广泛受欢迎，网络犯罪是一个严重的问题，人们的电脑会很容易受到攻击，因为网络罪犯无处不在。私人电脑不再是完全安全的，我们必须采取一些措施来应对网络犯罪。政府应该加强法律，给予网络罪犯以沉重的惩罚。擅长电脑技术的人应该通过受训来改善电脑防御系统和建立更多有效的防火墙。而且，人们应该注意不要点击不合法的网站。所有的这些措施实施是为了保护电脑的安全，但是这仍然有很长的路要走。

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.

Best regards,

Yours truly，

Zhang Hua

消防安全你我他，保障安全靠大家。这句话在街道上都可以看到。然而，我们做到了吗?我们想到了吗?

据统计，20__年除夕到初一两天，全国就发生火灾1602起，死亡一人，受伤3人。看着这些数字，就已经触目惊心。更何况还没有说刚发生的火灾。

20__年1月27日，巴西一家夜总会发生大火，据最新消息，这场火灾已导致245人死亡，数百人受伤。起火原因现已查明，是因为，一所大学的学生到这里聚会，在乐队进行烟花表演时，一个烟花弹射中了天花板，导致天花板着火，让许多学生窒息而死，况且这家夜总会只用一个出口，导致学生在出口拥挤，又使很多学生踩踏而死。目前火已扑灭，学生尸体放在一个体育馆里。

同学们，我们虽然知道消防安全，但是也许做不到，我们一定要重视消防安全，是安全在我们心中。

In spite of objections from public opinion， many students cant draw themselves away from video games. It seems that the more they are prohibited from playing the games， the more they are tempted to do so. Many students indulge themselves in playing these games.

Video games are harmful to both the inzidual and society in many ways. First， they endanger the young peoples health. Sitting in front of the computer for hours on end is bad for the players eyesight as well as his entire physique. Secondly， they distract the young people attention from their work and study. Absorbed in the games， the player often forgets to go to work or class. Sometimes even if they are at work or in class， they are still thinking of the games they played or are going to play after work or after class. As a result， they quickly fall behind others in their work and study. Thirdly， they lead young people to moral degradation. Some young people are especially interested in games that are filled with violence. If they play these games a long time， they may also settle disagreements through violence， which may give rise to higher crime rate.

Therefore， it is time we took effective measures to solve this problem. On the one hand， young people should be made fully aware of the danger of video games. On the other， illegal video game houses should be eliminated， and software producers should be encouraged to make more beneficial video games in the future.

As a product of modern computer and the Internet, online games have become very popular among college students. Many students have enjoyed great pleasure and satisfaction from these games. But as we see, some students lacking self-discipline are too much indulged in these games so that their health and academic performances are affected. This phenomenon has caused much worry from the teachers and parents.

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 college students much pleasure and release their pressure greatly.

From my point of view, online games are a wonderful entertainment if you play them in a clever way. When they interfere too much with your study, it is better for you to give them up at once. But if you have enough self-control over them, you can certainly obtain real pleasure and benefit a lot from them.

作为现代计算机和互联网的产物，网络游戏已经在大学生中很流行。许多学生都已经从这些游戏中获得了快乐和满足。但是我们看到，一些缺乏自律的学生沉迷于网络游戏，影响了他们的健康和学习成绩，这种现象引起了许多老师和家长的担忧。

然而，有些人认为网络游戏并不总是有害的。他们可以培养青少年的快速响应能力。此外，还可以激发他们的想象力和他们对计算机科学的兴趣。更重要的是，它给大学生带来快乐并且很好地释放他们的压力。

从我的角度来看，如果你发挥他们的聪明的作用网络游戏是一个很好的娱乐。当它对你的学习干扰太多时，你最好马上放弃它。但是如果你有足够的自我控制能力，你就能得到真正的快乐，并从中受益很多。

A couple of years ago, individuals can only take courses at real schools. In other words, only when they go out to schools by themselves will they have lessons which they want to have. However in recent years, with the development of internet and education mode, online teaching has become increasingly common. This kind of teaching mode means that a student just needs to have classes sitting in front of a computer at home, which appealing to lots of people.

It is widely acknowledged that online teaching has its apparent merits. First and foremost, shared resources online are accessible to all people, which costs a little at the same time. This feature brings about significant benefits especially to those who fail to afford that many courses at real schools. Secondly, online teaching makes it come a reality that one is able to study at the best pace suitable for him according to his own schedule. Last but not least, studying at home without going out is much more comfortable as well as convenient to busy people in contemporary society.

Meanwhile, there is no denying that online teaching also has demerits that cannot be dismissed. For one thing, online teaching, not like face-to-face teaching, lacks interaction between teachers and students, causing teachers not to receive feedbacks from students in time. For

another thing, for people who are poor at self-discipline, learning online at home will be a less effective way since they are easier to be distracted by other things. Besides, all of online teaching courses are ready-made rather than custom-made, that is to say, it is troublesome to be flexible when changes are needed.

With the widespread of Internet, people seem to depend on it greatly. Since we have Internet, our life changes a lot. Each day, we can get information of other countries or places of the updated information. We can share our experiences with others, enjoy a lot of good things and learn much knowledge from Internet.

Beside, lots of people put lots of short video on Internet to teach others.

Secondly, by Internet, we can contact anyone we want. Internet offers us a passage to contact with others by some applications. The only thing we need to do is to download some soft wares and install them so that we can contact with our families or friends. Besides, we can use many free resources by checking the Internet.
