专业英语的时态特点
❖ 就时态而言，因为专业科技文献所涉及的内容 （如科学定义、定理、方程式或公式、图表等） 一般并没有特定的时间关系，所以在专业文献 中大部分都使用一般现在时。
❖ 至于一般过去时、一般完成时也在专业英语中 经常出现，如科技报告、科技新闻、科技史料 等。

准确性
专业英语的准确性主要表现在用词上。然 而在语法结构上也有其特点。例如，为了 准确精细地描述事物过程，所用句子都较 长有些甚至一段就是一个句子。长句反映 了客观事物中复杂的关系，它与前述精练 的要求并不矛盾，句子长结构仍是精练的， 只是包含的信息量大，准确性较高。

专业英语的语法特点
❖客观（objectivity） ❖精练（conciseness） ❖准确（accuracy）
专业英语中的长句
❖ 面对长句，要进行语法分析。
❖ 语法分析主要从两点入手，第一是找出谓语，然后找 主语。一般英语句子不像汉语那样经常省略主语，而 是由主语和谓语一起构成句子的核心。
❖ 第二是找出连接词。英语和汉语的另一个不同是汉语 句子的分句之间常常没有连接词，而英语句子和分句 之间一般都有连接词连接。

这是由一个主句和四个从句组成的复杂长句，只有进行必要的语法分析， 才能正确理解和翻译。现试译如下： 除非相信那些机器造出的产品卖给消费者的价格足够支付所有成本，否则 厂家是不会买那些机器的。 节译：要不相信那些机器造出的产品售价够本，厂家是不会买的。 后一句只用了24个字，比前句40个字节约用字40%，而对原句的基本内容 无损。可见，只要吃透原文的结构和内涵，翻译时再在汉语上反复推敲提 炼，复杂的英语长句，也是容易驾驭的。

• Main articles: CPU design and Control unit
• The control unit (often called a control system or central controller) manages the computer's various components; it reads and interprets (decodes)(6) the program instructions, transforming them into(7) a series of control signals which activate other parts of the computer.注3 Control systems in advanced(8) computers may change the order of some instructions so as to improve performance(9).

Text A The function of computers
• Inside each of these parts are trillions of small electrical circuits(4) which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a "1", and when off it represents a "0" (in positive logic representation). 注1 The circuits are arranged in logic gates so that one or more of the circuits may control the state of one or more of the other circuits.

System Clock
Within the computer, events happen at a pace controlled by a tiny electronic “drummer”, called the system clock. The component is an electronic circuit that generated pulses at a rapid rate, measured in millions of cycles per second (MHz). Note that the system clock doesn’t have anything to do with keeping the time and date; the system clock synchronizes the computer’s internal activities. Synchronize : 同步
Control Unit
The control unit coordinates and controls all the other parts of the computer system. Under the direction of a program, the control unit manages four basic operations:
Power supply
A computer’s power supply can transform the alternating current (AC) available from standard wall outlets into the direct current (DC) needed for the computers operation. It also steps the voltage down to the low voltage required by the motherboard.

I. Introduction
• An operating system (OS), in computer science, is the basic software that controls a computer. It has two major functions: it coordinates and manipulates computer hardware.
Computer hardware is the equipment involved in the function of a computer and consists of the components that can be physically handled. The function of these components is typically divided into three main categories: input, output, and storage. 计算机硬件设备参与功能的计算机并构成 的组件,这些组件可以被物理处理。这些组件的 功能通常分为三大类:输入、输出和存储。

1.2 Computer Generations
1.2.5 Generationless Computers We may have defined our last generation of computers and begun the era of generationless computers. Even though computer manufacturers talk of “fifth” and “sixth”-generation computers, this talk is more a marketing play than a reflection of reality. 我们可能已经定义了我们最新一代计算机而且开始了计算机的无代时代。 即使计算机制造商谈到“第五”和“第六”代计算机,这些说法更多是市 场行为，而不是真实的反映。 Advocates of the concept of generationless computers say that even though technological innovations are coming in rapid succession, no single innovation is, or will be, significant enough to characterize another generation of computers. 无代计算机的观念提倡者说，即使科技革新接二连三地迅速出现,没有一 种革新是,或将是足够重要，作为另一代计算机的特征。
