Computers
Computers don’t look like anything we use in daily life. And sometimes they occupy① a great deal of② space and time. Although they have their own style and ways to operate, they are very useful and helpful to human beings.
Unlike people, computers don’t need coffee break, sick leaves or vacation. A computer can work continuously or continually throughout a day, a week or a month, and never goes on strike③ unless the power supply④ is switched off⑤ or the chip breaks down. In short⑥, it doesn’t feel tired and the productivity is very high. We can use it to process data to programme, calculate, and even do whatever it can.
But, computers can’t think for themselves now. Although sometimes we say the computers are intelligent and once during the chess they can beat the human beings, they can’t reach the same level of thinking like mankind. They can only deal with⑦ the things that have been programmed or instructed by humans. And they have no emotions. After all, a computer is just a kind of tool with which for us to accomplish⑧ some complex work.
【注释】
①occupy：霸占；占用
②a great deal of：（常接不可数名词）许多，大量
③go on strike：举行罢工
④power supply：供电
⑤switch off：关掉，割断
⑥in short：大略地说，总而言之
⑦deal with：办理，对付
⑧accomplish：完成，办理
【点评】
这是一篇根据段首句展开的议论文。本篇作文的论题是“Computers”，即对打算机进行论述，而论述的重点放在打算机的特色上。文章分为三段，三段不仅各自自成体系，而且又统一归纳到“打算机的特色”这一要点底下。
第一段先写打算机的“分外性”，即打算机不同于一样平常的日常生活用品，虽然它既霸占空间和韶光，但对人类却非常有用。第二段写出打算机的“独特性”，这一特色可以通过与人类比较后得出。除非电源坏了或芯片坏了，打算机可以连续事情，并且效率很高。我们可以利用它干许多事情。第三段指出它的“缺陷”，可通过和人类比较后得出：打算机不能像人类一样“思考”，终极要由人类来掌握。
文章的结尾通过写出打算机的实质特色即“a kind of tool”来照料全文，并将其“分外性”、“独特性”等特色归纳于标题之下，统领全文。
