A.machine B.computer C.keyboard D.mouse 5.Which of the following is not the stage of programming? A.Write a program. B.Debug the program. C.Print the program. D.Compile the program. 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 Business Week,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. 6.A computer virus is a computer program that is created to make and spread of itself.

That can be the end of a boat, and the end of everyone in it. Accidents can happen easily and quickly. One family had an accident with some big fish. (Perhaps it wash’t an accident for the fish). The fish swam under their boat and bit holes in it. The sea came in, of course, and they all got into that. They lived and hoped for many days. They ate and slept, and they always hoped... At last a ship found them. How do people live in a very small life-boat? Perhaps for weeks or months? They must be strong in every way. They must have hope -- they must want to live. But you can not eat and drink hope. You cannot drink sea water. Drink a lot of sea water -- and you will quickly die. Sailors can drink rain water. They must catch rain water in their boat. They must also catch fish and birds for food. Life-boats do not often carry a cooker, and so the sailors cannot cook their food. Raw fish and bird -- meat is not very nice, but there won't be any choosers in a life-boat! Tile sailors must eat raw food or they will die. What do people think about in a life-boat? They think about land, a warm bed dry clothes, fresh water and food, food, food. 11. Which of the following is not correct?_______ A. People may have to live for weeks on a life-boat. B.

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.

You can meat in a life-boat A. cook B. not cook C. not eat D. not carry 15. When they are in trouble in the sea people most probably always think about . A. sea water B. rough sea C. accidents D. none of these Passage D 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. Tell whether the following statements are true(T) or false(F) according to the passage（根据上文的内容判断下列句子的正误） 1. With the development of computer, the physical size of the CPU has often become bigger and bigger.( ) 2. The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input /output devices is controlled by the control unit of the CPU. ( ) 3. The CPU comprises the control unit and memory. ( ) 4. The control unit performs all the arithmetic and logical (comparison) functions( )
