随着科技的发展，电脑在二十一世纪成了人们必要的用品。随之而来，网络与我们的生活息息相关，给现代人的生活、工作带来了无与伦比的方便。

通过网络，我们能查寻有用的资料,了解时事动态等等.当你工作了很长时间后去玩电脑游戏，可以减缓你的精神压力，放松你的心情.并且，上网玩游戏也不完全是坏事，因为学生玩游戏可以锻炼手、脑的反应能力，满足学生娱乐需要。

但是网络也有弊。长时间的看电脑,电脑发出的辐射对人体有很大的害处。眼睛长期处于紧张状态容易造成近视。现在的电脑游戏众多,某些电脑游戏粗制滥造,甚至含有暴力等不健康内容。有的孩子由于对社会认识不足和自我保护意识缺乏，沉迷网络游戏，网络交友。

其实网络并不可怕，只要我们面对网络时多一些认识，网络就会成为我们学习上的有利助手。让我们一起创个干净的网络世界吧 ！

With the development of the science and technology, the computer has been becoming the necessity for people in the 21st Century. Following, network is of close link with our life, bringing us incomparable convenience on our life and work.

Through the network, we can search for useful data and get to know the current events. When you play computer games after a long-time work, it can relieve your pressure and make you feel relaxed. Besides, playing online games is not all bad, for it can fulfill students' entertaining requests as well as practice their

response ability.

However, there still exist some disadvantages in the network. The radiation from the computer will do harm to people's health if you keep on watching the computer for a long time. And short sight may cause by it for your eyes stay tense. At present, there are too many games on the Internet, but some of them are not of good quality even containing some unhealthy content like violence and so on. Duo to the lack of recognizing society and self-protection awareness, some students get addicted in the games and online dating.

In fact, network is not that horrible, as long as we know more about it, it will become our right hand on our studies. Let's build a clean network world together.

手机的利弊

Cell phones have become increasingly popular in China these days. Wherever you go you can see people using cell phones. Many college students, even high school students, have cell phones.

Cell phones have brought people a lot of benefits, but the most important is that they are convenient. With cell phones in their hands, they can keep in touch with anybody they want. If they want to get some information from the Internet, they can easily have their dream realized via cell phones too. Furthermore, if someone has a heart attack or a traffic accident, a call to emergency hospital or to the police can quickly bring him the help he wants.

However, cell phones can also bring people problems. The most serious is the electric wave radiation which is thought to be harmful to users' brains. Another problem is that when people are having a meeting or having a class or at a concert etc., the ring of the cell phone may interrupt others. So I think people should use cellphones as little as possible and turn them off when they are attending important meetings or attending classes.

科技发展的利弊

The rapid development of science and technology has brought about great changes to human life. The great benefit brought about by this progress is hailed in every corner of the world. New electronic appliances have made our life simpler than ever before. New inventions have helped us to organize our daily activities. Our job can be done faster. Mobiles and QQ have made it easier to communicate with other people. Internet has enabled us to know and understand other culture and society better.

However, the disadvantages about this development should not be neglected .Some of scientific inventions have even caused great harms or disasters to mankind. For example, advanced technology can be easily manipulated by irresponsible persons. Besides, we will be too dependent on it. When technology fails, we are helpless

Sometimes, it affects our health and life styles (we'll be complacent and lazy.) The chemicals may be hazardous).What's worse, Science and technology may even

destroy our simple and healthy life (Sometimes How we miss the traditional style of living!). In addition, the appearance of new technology may invade our privacy.

To sum up, humans must be alert against the possible harm while enjoying the benefits from them.

机器人的利弊

Intelligent machines such as robots are increasingly being used. They can do many things that used to be done by human. Discuss the benefits and dangers.

For centuries, people have fantasized that someday machines could have intelligence like mankind and work as faithful servants. Today this dream has come true in many fields thanks to rapid development in artificial intelligence research. Wonderful as this seems, machines have problems.

To begin with, people lose jobs when machines take their places, especially in the mass production industry such as automobile business. In factories of the famous car company Ford, almost every step of car making is done by giant robots that work faster with higher reliability and precision than human labor. Because of the adoption of robots, thousands of workers are put out of their old jobs and forced to make changes in their work. Even such changes create job opportunities because robots need people to take care of and operate; the number of new jobs is much smaller than that of lost, thus causing huge pressure on the labor market and government.

People become less smart because of the wide use of machines in their life. Nowadays people need to use their brain less than they did in the past. Everything is programmed and the only thing we need to do is to push a button or throw on a switch. This has given us great convenience but made us lazier and less smart. Everyone has the awkward moment troubling with the spelling of a simple word when writing with a pen. But with a computer, it will automatically proofread the spelling and grammar of your writing. So people become less concerned with learning things right. This is not a progress but a regress of our intelligence and culture.

But machines have many benefits that nobody can deny such as great work efficiency and low cost of mass production. The workload that could take months to finish by manual labor could be done flawlessly by robots in minutes. We have more purchasing power to enjoy a wider variety of goods and services because of the reduction of production costs with factories using machines. Other benefits include that machines could do dangerous jobs for people in high risk businesses like mining and construction.

To conclude, machines have many merits that make our life easier and more convenient, but they have caused many problems such as undercutting our job opportunities and overdependence on machines.

Future trends in computer science is one of the artificial intelligence，It is the

research and artificial simulation of human thought and eventually be able to make a human like to think the same machine. For human services and to help people solve problems.

After all, people thought it was unique, there are feelings, there is a variety of character, this will be very difficult to achieve in the machine. In fact, to do the same as the human thinking machine, the only one of the artificial intelligence, is by no means all. Through the study of artificial intelligence, can resolve all kinds of scientific problems, and promote the development of other science, the artificial intelligence is the best!

I believe that the science of artificial intelligence is waiting for humanity to explore it step by step the real connotation.

Computers are good or not

In the last hundred years, people have set a new mind-blowing rate for the developing of new technologies. New produces are being conceived every minute of every day, all of which will impact people in some respects. However, in all these technologies and produces computers have been the most important influences on people. Some people assert that computers have made life more complex and stressful, while some people believe that computers have made life easier and more convenient. From my point of view, the advantages of computers are the

leading sides and computers become a necessary part in people＇s lives. Perhaps computers may quicken our pace of life and make our life more complex and stressful. With the development of computers almost every jobs need people who are well up in computer technology. People, who want to find a good job, must learn how to use computers. On one hand, the computer technology is a very complex subject. If you want to use computers very well, you must take a lot of time to study and practice it. On the other hand, computers develop so fast that people must study new technology constantly. Those all make people feel stressful. Even though there may be one or two disadvantages to develop computers, the advantages fast outweigh them. The major point for my penchant for computers is that computers can help people do many things, including complex computation, storing and searching information and some work that is dangerous for people to do. For instance launching a rocket up to outer space needs so complex computation that people cannot do it without computers; searching the newest information is of vital importance for business, so people will not be success in business without computers. Computers have facilitated many of our working processes and we have already grown dependent on them. Another advantage of computers is that people can use them for entertainment in spare time. From pc games to online chatting, computers have the ability to entertain us in a wide verity of ways. After a busy day, playing pc games is the favorite thing of most of my classmates. And in today＇s life, a lot of young people could have not televisions, but they must have a set of computer. Now many films display fascinating images by using computers to deal with them. In a word in spite of the fact the computer appears to have made life more complex and stressful, I fell that the advantages are more obvious. Computers have become an integral part of

everyday life. They can help us do much work and make us funny.

核能的利弊

Nuclear power plants provide about 17 percent of the world's electricity. Some countries depend more on nuclear power for electricity than others. In France, for instance, about 75 percent of the electricity is generated from nuclear power. There are more than 400 nuclear power plants around the world.

To build a nuclear reactor (核反应堆),what you need is some mildly2 enriched uranium(铀). Uranium is a fairly common element on Earth,incorporated3 into the planet during the planet's formation(形成). U-235 is one of the few materials that can undergo4 induced fission(诱发性核裂变). Raising and lowering the control rods(杆，棒条) allow operators to control the rate of the nuclear reaction. When an operator (操作员) wants the uranium core to produce more heat, the rods are raised out of the uranium bundle(捆，束). To create less heat, the rods are lowered into the uranium bundle. The rods can also be lowered completely into the uranium bundle to shut the reactor down in the case of an accident or to change the fuel. The uranium bundle acts as an extremely high-energy source of heat. It heats the water and turns it to steam. The steam drives a steam turbine(汽轮机), which spins5 a generator(发电机) to produce power.

Well-constructed nuclear power plants have an important advantage when it comes to electrical power generation——they are extremely clean. Compared with a coal fired power plant, nuclear power plants are a dream come true from an

environmental standpoint (立场，观点). Unfortunately, there are significant problems with nuclear power plants. Mining and purifying(提纯) uranium has not, historically, been a very clean process. Improperly functioning nuclear power plants can create big problems. The Chernobyl6 disaster is a good example. Spent fuel from nuclear power plants is toxic (有毒的) for centuries, and, as yet, there is no safe, permanent(永久的) storage facility for it.

The nuclear crisis in Japan has developed rapidly, which makes us to think over about exploration of nuclear power. Fears about nuclear safety which took a generation to overcome have appeared again.

Supporters of nuclear power say nuclear power produces nearly no conventional air pollution, which is called as \"clean energy”. Besides, our technology develops quickly. Therefore, risks such as natural disaster can be avoided. we can benefit from the exploration of nuclear power.

However, opponents worry that the complexity of design and engineering of nuclear plants(核电站)Any failure or operation error could lead to serious result. It will pollute soil and plants and do harm to humans and animals.

In my eyes, we should continue the exploration of nuclear power. Not only does it bring lots of profits but also it is the best choice we have. Compared with other energies like sunshine, wind, and garbage, it is best to solve the shortage of coal and natural gas. As you know, it is the most efficient and realistic means of meeting the rapidly-growing demand for power.

关于远程网络教育利弊的英语作文

With the popular visitation of the internet, network classrooms are gaining more and more popularity. As a new teaching pattern, network classrooms have become an effective compliment to traditional classrooms. So some people propose on question “Will network classrooms replace traditional classrooms?”

As to this question, the opinions vary from one to another. Some people think it quite possible for network classrooms to take the place of traditional classrooms. First, network classrooms needn’t have face-to-face communication, and are not limited by time and place, which facilities both teachers and students. Secondly, network classrooms release teachers from repeating the same contents. Since the video or audio material can be played time and again.

However, many people have opposite stand points. They say that with online courses students like direct communication with teachers and their confusion cannot be solved instantly. In addition, the computer system cannot be guaranty to work staidly all the time. Personally, both network classrooms and traditional classrooms are necessary for students. If traditional teaching patterns and motor ones like network classrooms can be combined together, more fruitful education is sure to be realized.

2关于软件翻译与人工翻译对比的英语作文

Machine Translation and Human Translation

In recent years, all kinds of electronic dictionaries and translation software have been developed. With the development of technology, these electronic dictionaries and software can help us translate not only words and phrases, but even sentences and paragraphs. So some people come to the conclusion that machine translation will replace traditional human translation. However, I couldn't agree with this argument.

Admittedly, translation machines and software bring much convenience for our study and work. With them, we needn't bother to live through the heavy dictionaries. However, machine translation has its disadvantages. First, generally speaking, translation software only can give direct translation, which is sometimes not in accordance with the original articles in logic and meaning. Second, some people depend on electronic dictionaries and software too much, which is unfavorable to their improvement in language ability.

Considering the above mentioned, I think that machine translation cannot replace human translation, but it is a good complementary to human translation. Therefore, we should combine machine translation with human translation effectively.
