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
e-mail 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.
Choose the best answer according to the passage.(根据上文的内容选择正确的答案。每小题2分，共10分) 1．A computer virus is a computer program that is created to make and spread _______ of itself.

4．Trojan Horses _____________________________________________.
A．quickly replicate itself and gradually attache to files, programs or the hard drive.
B．infect the computer without even having to click open email attachment or any program.
C．allow hackers to take control over a particular system or to steal very important data.
D．avoid the virus to attack computer.
5．According to BusinessWeek, the ____________ attacks reported in the first half of 2003 nearly match previous year's total number .
A．86,404 B．76,404 C．56,354 D．34,876
Software testing
Software testing, which is defined as the execution of a program to find its 【1】, is a vital part of the software 【2】. There are different types of testing, mainly, they are【3】or functional testing, which
tests whether the 【4】is the expected result with the 【5】input; and 【6】(or glass box testing) which is performed to【7】problems with
the【8】structure of a program. Debugging is the process of analyzing and locating bugs when
software does not behave as expected. Software testing is a much more 【9】 means of identifying software 【10】 .Therefore, debugging supports testing other than replacing testing.
The Operating System
The operating system is a 【11】 of system programs that, when executed, controls the 【12】
of the computer. Sophisticated operating systems increase the 【13】 and consequently decrease the
【14】 of using a computer. Operating systems provide a software 【15】 , on top of which other programs, called 【16】 programs, can run. The application programs must be written to run
on 【17】 of a particular operating system. Your choice of operating system, therefore, determines, to a great extent, what applications you can 【18】 . For PCs, the most popular operating systems are DOS, OS/2, and 【19】 , but others are 【20】 , such as Linux.
Choose the best answer for each of the blanks.
Whenever new information is entered, it must 【1】 somewhere in the computer ’s 【2】 . Later, the CPU must also be 【3】 to get this information from memory. This is where RAM is
needed. The CPU can 【4】 write to and read from RAM. RAM is called Random Access Memory
【5】 the CPU can do directly to any memory location in it. The CPU does not have to look 【6】 all of RAM to find the spot it needs. But RAM only 【7
】 the data temporarily. As soon as you switch the computer 【8】 , all that information disappears from the RAM. When you switch the computer on again, the RAM is 【9】 , and ready 【10】 a new program and new data.
