We are becoming increasingly dependent on computers. They are used inbusinesses, hospitals, crime detection and even to fly planes. What thingswill they be used for in the future? Is this dependence on computers agood thing or should we be more auspicious of their benefits?Personal computers were introduced as recently as the earlyeighties. In this short time they have made a tremendous impact on our lives. Weare now so dependent on computers that it is hard to imagine what things wouldbe like today without them. In the future computers will be used to create bigger and even more sophisticatedcomputers. The prospects for this are quite alarming. They will be so complex thatno individual could hope to understand how they work. They will bring a lot ofbenefits but they will also increase the potential for unimaginable chaos. By then it might be too late I believethat it is very important to be suspicious of the benefits that computers will bring.

With the development of science and technology, computers have entered the lives of many people. Last year, I also have a computer, it brings me a lot of convenient, make me grow their knowledge, broaden the horizon. The computer can be divided into three main parts, display, host and the keyboard. Display is a big screen, like TV, show a variety of ICONS. Host is the "heart" of the computer, have two eyes, one big one small, start a program, the other a restart the program. Credit is the largest keyboard, it contains 26 English letters, four key direction, 10 Numbers, some indispensable function keys. Their respective keep on their own, give priority to people. Computer and a small tail, it is the mouse, the mouse is used to issue instructions, the display will follow its instruction, this is the magical function of the computer. Also known as the electronic computer, computer is scientists after years of research to invention. Electronic computers after several generations of "reproduction" became "versatile" computer. Computer can surf the Internet, online content is rich and colorful. Mechanism can be found in their favorite books and articles. Chat room, I can always chat with net friend, talk about the topic you want to talk about make more friends, to understand the character of others don't see the computer body hard, if meet its Nemesis - electronic virus, consequence will be unimaginable. But you can open 360 anti-virus software, the virus can be eliminated, just like drink the medicine to the patient. At present, science and technology is developing rapidly, I firmly believe that the computer in the next few years 随着科技的发展，电脑已经进入了许多人的生活。去年，我也有了一台电脑，它给我带来了很多方便，使我增长了见识，开阔了眼界.电脑分为三大主件，显示器，主机和键盘。显示器就是一个大屏幕，像电视机一样，显示出各种各样的图标。主机是电脑的“心脏”，有两只眼睛，一大一小，一只启动程序，另一只重新启动程序。功劳最大的就是键盘了，它包含着26个英语字母，4个方向键，10个数字，一些不可缺少的功能键。它们各自守在自己的岗位上，为主人服务。电脑还有一条小尾巴，就是鼠标，鼠标是用来发布指令的，显示器会听从它的指令，这就是电脑的神奇功能。 电脑又称为电子计算机，是科学家们经过多年研究才发明来的。电子计算机经过几代的 “繁衍”成为了 “多才多艺”的电脑。电脑可以上网，网上的内容更是丰富多彩。书库中可以找到自己所喜爱的书籍和文章。聊天室里，我可以随时和网友聊天，谈自己想谈的话题交更多的朋友，了解他人的性格 别看电脑的身体硬，要是遇到它的克星--电子病毒，后果将不堪设想。不过你可以打开360杀毒软件，病毒就可以消灭了，就像是给病人喝药一样。 目前，科技正在飞速发展，我坚信，电脑在今后的几年里一
