個人計算機(jī)的奇妙結(jié)構(gòu)
【內(nèi)容提示】
學(xué)校要出壁報，約你用英語寫一篇介紹個人計算機(jī)的文章。內(nèi)容包括：
①計算機(jī)的工作過程與人的大腦的思維過程相似，所以又叫電腦。
�、趶耐庥^看，個人計算機(jī)有三部分：主機(jī)、鍵盤和顯示器。
�、蹚挠嬎銠C(jī)的工作過程看，計算機(jī)系統(tǒng)是由軟件和硬件組成的。硬件好比人的軀體，軟件好比人的靈魂。
�、芸刂朴嬎銠C(jī)的技術(shù)叫做軟件，計算機(jī)及其各種設(shè)備本身叫做硬件。
�、萦嬎銠C(jī)的工作就是通過其軟件，利用計算機(jī)的各種資源，指揮硬件實現(xiàn)無所不能的奇妙用途。

The Wonderful Structure of a Personal Computer
In Chinese, a computer is popularly known as an “electrical brain”, for the working process of a computer is similar to a human brain very much.
In appearance, a personal computer has three simple and clear parts: the main frame①, the keyboard② and the display③. In other words, if you own these three parts, you would exactly have a computer.
A computer system is made up of software and hardware considering its working manner. If we compare the hardware to a human body, then, the software would be the soul.
Just as a driver cannot drive a car without driving skills or the car it self, you cannot control a computer without controlling techniques or the computer itself. The controlling techniques are called software, while computers themselves and related devices④ such as a mouse⑤ are called hardware.
The work of a computer is just making full use of various resources by a software set in the computer, and directing the hardware to realize marvelous omnipotent⑥ functions.
【詞語解釋】
①main frame 主機(jī)（箱）
�、趉eyboard[＇ki:b&:d]n.鍵盤
�、踕isplay 顯示器
④related devices 相關(guān)部件
�、輒ouse 鼠標(biāo)
⑥omnipotent[&m＇nip+t+nt]a.無所不能的
【寫法指要】
1）本文是知識介紹說明文，或構(gòu)造介紹說明文。文章主要介紹了計算機(jī)結(jié)構(gòu)的簡單知識，順便提及了它的功能。在正文里，作者采用空間順序?qū)懛�，由外部結(jié)構(gòu)寫到內(nèi)部結(jié)構(gòu)。最后用類比法（analogy）將計算機(jī)操作同駕駛汽車作了比較。
2）類比法是一種邏輯推理方法，人們在文章中經(jīng)常用到。英語中表達(dá)類比的方式有多種，本文用到的有“be similar to”，“compare…to…”，“just as”等。但是，類比法有或然性，須慎用。
