According to the mode of processing, computers are either analog or digital.They can also be classified as mainframes, minicomputers, workstations, or microcomputers.All else (for example, the age of the machine) being equal, this categorization provides some indication of the compu ter’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC(通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV. Translate the following passage from English into Chinese:计算机将变得更加先进，也将变得更加容易使用。

The system must first authenticate（验证）a user seeking access. Typically the authemiccition function determines whether the user is permitted to access the system at all. Then the access control function determines if the specific requested access by this user is permitted. A security administrator maintains an authorization（授权）d-sbase that specifies what type of access to which resources is allowed for this user. The access control function consults this database to detemine whether to grant access. An auditing function monitors and keeps a record of user accesses to system resources.In practice, a number of com—cmetus may cooperatively share the access control function. All mii,戏systems have at least a rudimentary（基本的），and in many cases a quite robust. access control component. Add-on security packages can add to the witi*access control capabilities of the OS.

Fill in each of the blanks with one of the words given in the following list, making changes if necessary:We can define a computer as a device that accepts input, processes data, stores data, and produces output. According to the mode of processing, computers are either analog or digital. They can also be classified as mainframes, minicomputers, workstations, or microcomputers. All else (for example, the age of the machine) being equal, this categorization provides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes. First-generation computers of historic significance, such as UNIVAC (通用自动计算机), introduced in the early 1950s, were based on vacuum tubes. Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers, dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to be incorporated on one chip. Fifth-generation computers are expected to combine very-large-scale integration with sophisticated approaches to computing, including artificial intelligence and true distributed processing.IV. T ranslate the following passage from English into Chinese: 计算机将变得更加先进，也将变得更加容易使用。

Part3 Listening and SpeakingListening Comprehension1. B2. A3. DOriginalRoadrunnerOn the current TOP 500 list of worldwide supercomputers released in June 2008, Roadrunner, IBM's new super computer, is rated No.1, exceeding IBM Blue Gene, the former No.1 on the list. IBM calls Roadrunner the world’s first “hybrid” supercomputer. It combines 12,960 IBM Cell chips, which power Sony's PlayStation 3 video game machine, with 6,948 dual-core AMD Opteron chips and 80 terabytes of memory. It runs Red Hat Linux.Roadrunner is billed at the fastest in the world, operating at one petaflop or one thousand trillion calculations per second. So, exactly how fast is the supercomputer? IBM said the speed is roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers - users would need a stack of laptops 1.5 miles high to match Roadrunner's performance. It would also take the entire population of the earth - about 6 billion people - each working a handheld calculator at the rate of 1 second per calculation more than 46 years to do what Roadrunner can doin one day.IBM said that in the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 tri-blade units have the same power as the 1998 fastest computer. Now, a complex physics calculation that will take Roadrunner one week to complete would have taken the 1998 machine 20 years to finish.Dictation1. twentieth century2. citizen3. mathematical4. early development5. career6. stored7. memory8. operate9. electronic 10. calculation 11. memories 12. manner 13. control unit 14. calculating unit 15. control unit 16. a piece of data 17. accordingly 18. advancement 19. architecture 20. majorityUnit 2Part1 Reading and TranslatingSection AⅠ. 1.
