Computer: Blessing or Curse

Looking back on the past 20th century, we human beings have every reason to take pride in all those great achievementsWe have conquered many diseases, launched satellites, invented mobile phones However, the advent of computer, together with the internet, is considered the most significant and has caused a thorough revolution in people‘s lives

When the first computer came into being in 1946, it was proclaimed the beginning of a new era in human history The marvelous invention coupled with Internet plays a vital role in today‘s society

Nowadays, businessmen depend substantially on computers In the database of the banks, the information of thousands of millions of accounts is stored accurately The B2B system of the Ford Car Company controlled completely by computers,makes it possible for the whole company to coordinate efficiently, thus it keeps the costs to the lowest level Stock transactions involving large sums of money can be completed safely through internet We can hardly imagine a business operating without computers

When it comes to our daily life, computers also demonstrate their advantages "distance learning" is becoming increasingly popular, by which teachers and students interact online while sitting before the PC at home And there‘s even possibility that it will take the place of the old way of teaching someday in the future

Besides, we can have easy access to the flowing information when necessary by clicking the mouse only In the past, bowerer, we have to search for hours in libraries PC games provide extra fun for our relaxation Emails facilitate communication between friends separated by long distance

While everyone says the 21st century is an information age,we should also take notice of its negative side Not all the changes brought to us are positive

I can still clearly remember the problem before the millenium that caused global panic It gave out the warning that people had relied too much on computers Once the system is ruined, it may give rise to collapse of the whole society Moreover, hackers attempt to destroy certain systems or make profits by stealing critical data; virus of different kinds are continually produced and spread on the net All these threaten our society As to individuals, spending much time on computer keeps one from communication with other people Students addicted to PC games are distracted from learning

In sum, it‘s no easy thing to define exactly whether the advent of computer is a blessing or a curse As far as I‘m concerned, despite the negative effects it brings about, the computer has improved our life and benefited us on the whole It‘s a great invention of the 20th century

简 评

新生事物的出现和发展具有两面性。所涉及的题材具有一定的典型性。90年代中期，随着电脑的'普及，越来越多的人开始关注这是好事还是坏事。对此显然不能轻易下结论。因此，客观地评述了电脑给人们带来的好处，同时也提出存在的问题。在前半部分列举了电脑的益处，在后半部分说明了电脑带来的问题。但从文章的着墨和用词可以看出的观点倾向。如文章不但分别从商务和生活两方面形象地描述了电脑带来的便捷，而且使用了如“proclaimed beginning Of new era，play a vital role，thousands Of millions Of accounts，stored accurately‘’这样的字眼。另外，文章中的过渡句选用了委婉的“while”和“not all changes brought to us are positive"来表示转折，这也预示了最终确认电脑利大于弊的观点。

As a kid, most of us like playing computer games or surfng on the internet Computer game is so fun that we are all interested in it and some students can't stop playing it But I think we can play it a few minutes if we have plenty of free time If we are tired of learning, we can play the computer games for a few minutes to relax ourselves But if we are busy in studying, we can't play it We can learn lots of knowledge from the internet, but we have to charge ourselves on the internet We shouldn't spend much time on the internet As a student, we should work hard at our books, because our main task is learning well Everything has two aspects, we must master ourselves on it So I will give you some advice as following:
1 You should finish your homework first, then you can play with the computer
2 You can't play with computer over half an hour each time
3 If you have some problems to look up, you can search them on the internet
4 You can only use the internet for learning

The disadvantage of the Computers
As all as we know,the computers do harm to our lifeFor example,if you play it for more than 2 hours ,you will feel very tired and your eyesight will get poorit's especially bad for studentssome students always play computer games all day long and they gradually hate to study and soon,they will fall behind othersWhat's more,when you play computer games,you will forget the realistic life,maybe you even kill yourselves!so, please don't play computer games to live a happy life!

今天，世界随着我们人类的科技变得更智能。如此，电脑便应运而生。但究竟
电脑，以我之见，我认为它在我们生活中扮演着重要的角色。我们每天都在用，我们每天都向它寻求帮助，我们早已离不开它了。
另一方面，然而，我们中的一些人特别是青少年，他们没日没夜地沉迷于电脑游戏。甚至，他们到了犯罪的境地，只因为想玩游戏而已。我们真应该关心和劝告他们。
最后，我先说的是，电脑是好是坏，关键是我们如何去使用而不是仅仅只看表面。
