计算机
计算机给我们的世界带来了许多变化，随着科学技术的发展，计算机在人类活动的各个领域中的使用年年增长，计算机对科学研究和工程学帮助很大，它们能以很快的速度运算，这些运算很复杂，要用人工运算需要几天甚至是几年。
一旦设计出程序，计算机可以以极高的速度自动运算。计算机不但可以搜集资料，而且可以贮存资料，不管什么时候需要这些资料都可以调出来。
但是计算机不会代替人。尽管计算机正在接替一度用我们自己的大脑去完成的工作，但是它们只不过是机器而已，它们决不会代替人。
Nowadays more and more families own private cars. Private cars, as the product of modem civilization, have been playing a vital role in people's daily activities. First, private cars are a convenient means of transportation. You can go wherever you like. Secondly, there is no doubt that private cars will have a great impact on the economic growth. The rapid car industry growth will contribute much to keeping the country's economy growing at a higher rate in the near futrue.
But every coin has two sides. The development of the private cars will bring about a series of problems. For example, the polluted air given off by cars will do great harm to our health, too many private cars will lead to traffic jams and a great deal of energy will be wasted and so on.
So I think we should take advantages of private cars and make them serve us better. Meantime we hope that satisfactory solutions to these negative problems will be found soon.
现在，越来越多的家庭拥有私家车。私家车作为现代文明的产物，在人们日常生活中扮演了重要的角色。首先，私家车是很方便的交通工具，你可以开车到处跑；其次，毫无疑问私家车对经，济的增长起到很大的作用。在不远的将来，快速发展的汽车工业在保持国家以较高速度的增长方面将做出很大的贡献。
当然，任何事物都有其两面性。快速发展的私家车会导致一系列问题。例如，汽车排出的废气对人体有很大的伤害，太多的私家车会导致交通阻塞，很多能源被浪费等。
所以我认为我们．应当充分利用私家车的优势，更好地为我们服务。同时，我们也希望不久这些消极的问题将会得到圆满的解决。
We can see around us that more and more students are going to own a mobile phone .From NOKIA to SIEMENS, from national to imported, from low price to high price…… Collected By www•ii63·com
As a communication device, the mobile phone benefits us a lot. We can use it to keep in touch with our families, our friends and our classmates wherever we are. In festivals, we can send short messages to wish good luck to other people we known. It brings us a lot of convenience. collected by II63·com
As a coin has two sides, the mobile phone also has disadvantages. We spend too much time on spelling our words and sending short messages that we can't focus on our studies. Also, you will always be annoyed by strangers' calls one after another.
In my opinion, we can use it. But we shouldn't spend too much time on it and don't let it disturb us from our studies. And we should not easily tell people our phone numbers who we don't recognize.
