There are 3 levels of pro

9、gramming 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

10、to choose which programming language is best suited for the job.Passage A：AD574A AD574 is a A/D converter which converts analogy signal into digital signal, and usually used in electronic technology, here is part from its handbook.Fig 1 AD574A1.Features (Fig 1)l Complete 12-Bit A/D Converter with Re

12、patible Versions (15 ms AD674B, 80 ms AD774B)2.Product Description The AD574A is a complete 12-bit successive-approximation analog-to-digital converter with 3-state output buffer circuitry for direct interface to an 8- or 16-bit microprocessor bus. A high precision voltage reference and clock are in

13、cluded on-chip, and the circuit guarantees full-rated performance without external circuitry or clock signals. The AD574A integrates all analog and digital functions on one chip. Offset, linearity and scaling errors are minimized by active laser-trimming of thin-film resistors at the wafer stage. Th

14、e voltage reference uses an implanted buried Zener for low noise and low drift. On the digital side, 12L logic is used for the successive-approximation register, control circuitry and 3-state output buffers.The AD574A is available in six different grades. The AD574AJ, K, and L grades are specified f

15、or operation over the 0C to +70C temperature range. The AD574AS, T, and U are specified for the 55C to +125C range. All grades are available in a 28-pin hermetically-sealed ceramic DIP. Also, the J, K, and L grades are available in a 28-pin plastic DIP and PLCC, and the J and K grades are available

16、in ceramic PLCC.(二) Read the passage A and answer the questions (3分+4分+3分)1. What is the function of AD574A?2. Translate the underlined sentences.3. How many grades are there of AD574A? and what are they?Passage B:The central processing unit (CPU) is the heart of the computer systems. Among other th

17、ings, 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

18、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.装 订 线The CPU comprises the control unit and the arithmeti

19、c / 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.Th

20、e 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 e

21、qual to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next. (三) Tell whether the following statements are true(T) or false(F) according to the passage B.（根据上文的内容判断下列句子的正误）（52分10分）1. With the development of computer, the physical size o
