and computers, is a ________________ for describing computation in readable form. There are 3 levels of programming languages, they are________________ , which can be run directly by computer; ________________ and _____________. There are different high-level programming languages. Fortunately, most of them have many kinds of construct in common and vary only in the way that these must be ________________ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job.

Passage A

The central processing unit (CPU) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and capacity have increased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.

The CPU comprises the control unit and the arithmetic / logic unit (ALU). The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.

The ALU performs all the arithmetic and logical (comparison) functions — that is, it adds, subtracts, multiplies, divides, and does comparisons. These comparisons, which are basically “less than”, “greater than”, and “equal to”, can be combined into several common expressions, such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.

（二）Tell whether the following statements are true(T) or false(F) according to the

Passage B

A computer virus is a computer program that is created to make and spread copies of itself. The program may however also be designed to have other effects on the systems it infects, ranging from the annoying to the disastrous.

Virus attacks are growing rapidly these days. According to BusinessWeek, the 76,404 attacks reported in the first half of 2003 nearly match previous year's total number . As new antivirus tools are more powerful than before, the virus writers are getting a lot smarter with newer and creative ways to attack network systems. Let's first examine some common virus types:

Basic Virus - a piece of software code that is developed to attack computers and network systems via email or Internet connections. It quickly replicates itself and gradually attaches to files, programs or the hard drive.

Trojan Horses - This is a program that doesn't replicate when entering a system but can be effectively used to open 'back doors.' Trojan Horses allow hackers to take control over a particular system or to steal very important data.

Worm - this type of virus is able to spread itself automatically over the network from

one computer to the next. During a worm attack, users' computers get infected without even having to click open email attachment or any program, etc.

Since it is very difficult to avoid the virus, your best defense is a powerful antivirus program. In order to fight with such viruses, the software vendors should focus on making their products more robust. This may ask for a trade-off between user-friendliness and security. In specific cases it may require line-by-line inspection, code retooling and even systems automation to defend the installed programs.

(三) choose the best answer according to the passage B. (根据上文的内容选择正确的答案。（10分，每题2分)

Passage C

The Internet, then known as ARPANET, was brought online in 1969, which initially

第 5 页 共 8 页

connected four major computers at universities in the southwestern US . The early Internet was used by computer experts , engineers, scientists, and librarians. There was nothing friendly about it. There were no home or office personal computers in those days, and anyone who used it, whether a computer professional or an engineer or scientist or librarian, had to learn to use a very complex system.

The Internet matured in the 1970's as a result of the TCP/IP architecture. As the commands for E-mail, FTP , and telnet were standardized, it became a lot easier for non-technical people to learn to use the nets. It was not easy by today' s standards by any means, but it did open up use of the Internet to many more people in universities in particular. Other departments besides the libraries, computer, physics, and engineering departments found ways to make good use of the nets -- to communicate with colleagues around the world and to share files and resources.

In 1991, the first really friendly interface to the Internet was developed at the University of Minnesota. The University wanted to develop a simple menu system to access files and information on campus through their local network.

Since the Internet was initially funded by the government, it was originally limited to research, education, and government uses. Commercial uses were prohibited unless they directly served the goals of research and education. This policy continued until the early 1990's, when independent commercial networks began to grow.

5. Which statement is not true according to Passage C?

A. Many more people in universities began to use the Internet in the 1970s, but it wasn't as user-friendly as today's standards.

B. The restrictions to commercial uses changed as the independent commercial networks were not funded by the government.

C. Commercial uses were allowed for the early Internet if they directly served the goals of research and education.

D. The early Internet was logged in from home or office personal computers.

(二) Translate the following paragraph into Chinese.（将下段文章翻译成汉语。）（共10分）

A high-level language is an artificial language with which we can write various instructions. This is possible not because computer processors are now so technologically advanced that they can ?understand? these languages. You should translate from programming languages into machine language which can be understood by the computer processors. Compilers can accomplish this task. This does mean that a high-level language program is not directly executable: it must be compiled to produce processor program, which is executable.
