例文：On Computers电脑的利弊

Nowadays, computers are very popular around us. Like everything else, computers have both favorable and unfavorable aspects. Generally, the advantages can be listed as follows.

First, computers can calculate. They can make work more efficient for they have a high speed of calculation. Besides, people can communicate with each other by E-mail, which costs people less money and less time. Most important of all, computers create wide communication around the world. People can communicate with each other by joining Internet. They can make friends all over the world.

But every coin has two sides. The negative aspects are also apparent. To begin with, since computers can do a lot of work for us, such as calculation, we may rely too much on them and become lazier and lazier. To make matters worse, although it is convenient for people to communicate with each other by E-mail, the original warm relationship may become cold, for people will have fewer opportunities to talk to each other face to face. Worst of all, computers will have virus caused by electronic hackers so that a lot of important information will be lost.

Through above analysis, I believe that the positive aspects outweigh the negative aspects. Therefore, I believe, computers will have a bright future.

Now, the Internet is playing an important part in our daily life. Recently , we have had a discussion about the advantages and disadvantages of the Internet . Different students have different opinions.

Some students think the Internet is good. We can learn the latest news at home and abroad. Almost all of us have a QQ or MSN, and we can get in touch with our friends easily. What’s more, we can send an e-mail to our friends and chat with them on the Internet. However , each coin has two sides. There are also some disadvantages. It is easy for us to make bad friends on the Internet . Many students are addicted to the Internet, which is bad for their eyes and health.

In my opinion，the Internet has both advantages and disadvantages. We are supposed to make good use of the Internet rather than get addicted to it.

网络的利弊

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
