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.

Acer E360 Socket 939 motherboard by Foxconn .svg
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。

多字节的另一个值得关注的问题是对齐问题。现代微处理器在某一时刻可以 读出多个字节。例如,摩托罗拉68040微处理器能同时读入4个字节的数据, 然而,这4个字节必须在连续的单元中,它们的地址除了最低两位不同之外, 其余的位均相同。该CPU可以同时读单元100、101、102和103,但不能同时 读单元101、102、103和104,后者需要两个读操作,一个操作读100(不需 要的)、101、102和103,另一个读104、105(不需要的)、106(不需要的) 和107(不需要的)。
一些CPU,特别是精简指令系统CPU,需要所有的数据都对 齐。其它的CPU不要求这样,它们通常能够在内部将数据对 齐。一般来说,不要求对齐的CPU具有更紧凑的程序,因为 没有单元因为要对齐而闲置不用。然而,对齐的CPU具有更 好的性能,因为他们读取指令和数据是需要更少的存储器读 操作。
2.3.5 Beyond the Basics(基本功能的拓展 )
对齐简单地说就使存储多字节值的起始单元刚好是某个多字 节读取模块的开始单元。在这个例子中,意味着多字节值开 始存储的单元的地址要能被4整除,这样就保证该4字节值可 在单一的一个读操作中存取到。
2.tion
Some CPUs, particularly RISC CPUs, require all data to be aligned. Other CPUs do not; they can usually align data internally. In general, nonaligned CPUs have more compact programs, because no locations are left unused by alignment. However, aligned CPUs can have better performance because they may need fewer memory read operations to fetch data and instructions.

• Most home users access the Internet this way.
Cable and Satellite Access
• Cable TV firms are increasingly offering Internet access at speeds much faster than dial-up modems.
• Satellite access enables fast downloads but requires a phone line and a modem for uploading data. • Like modem access, these access methods give your computer a temporary IP address.
Shell Access
• The least expensive type of internet access, this method requires a modem and a phone line. • You get access to the shell (user interface) of a UNIX computer, enabling you to use textbased applications such as E-mail. • UNIX knowledge is required for shell access. • Your computer isn’t really connected to the Internet. You’re using it as a terminal to access a computer that is connected to the Internet.
