C might be described as a "medium level language",Like a true high level language,there is a one-to-many relationship between a C statement and the machine language instruction it is compiled into. Thus a language like C gives you far more programing leverage than a low level assembly language.However, compared to most high level languange ,C has a very small set of constructs. In addition unlike most high level language ,C let you easily do chorse (such as bit and pointer manipulation) additionally performed by assembly languages, Therefore ,C is an especially good tool to use for developing operating system( such as the UNIX operating system),or other system software.翻译：C语言的开发始于20世纪70年代初期，现在已经成为非常流行的语言，C语言也许最适合被描述成为“中级语言”，。

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 A.（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.( F)2.The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU andinput /output devices are controlled by the control unit of the CPU.( T)3.The CPU comprises the control unit and memory. ( F )4.The control unit performs all the arithmetic and logical (comparison) functions。

Fill in each of the blanks with one of the words given in the following list, making changes if necessar(完形填空)(只选十个空)A programming language is a language used to write instructions for the computer. It lets the programmer express data processing in a symbolic manner without regard to machine-specific details.The difficulty of writing programs in the machine language of 0s and 1s led first to the development of assembly language, which allows programmers to use mnemonics (助记符)for instructions and symbols for variables. Such programs are then translated by a programknown as an assembler into the binary encoding used by the computer. Other pieces of systemsoftware known as linking loaders (连接装入程序) combine pieces of assembled code and load them into the machine’s main memory unit, where they are then ready for execution. Theconcept of linking separate pieces of code was important, since it allowed “libraries” of programs to be built up to carry out common tasks—a first step toward the increasingly emphasized notion of software reuse. Assembly language was found to be sufficiently inconvenient that higher-level languages (closer to natural languages) were invented in the1950s for easier, faster programming; along with them came the need for compilers,programsthat translate high-level language programs into machine code. As programming languagesbecame more powerful and abstract, building efficient compilers that create high-quality codein terms of execution speed and storage consumption became an interesting computer scienceproblem in itself.III. Fill in each of the blanks with one of the words given in the following list, making changes if necessary: (完形填空)(只选十个空)A compiler, in computer science, is a computer program that translates source code into object code. Software engineers write source code using high-level programming languagesthat people can understand. Computers cannot directly execute source code, but need a compiler to translate these instructions into a low-level language called machine code. Compilers collect and reorganize (compile) all the instructions in a given set of source code to produce object code. Object code is often the same as or similar to a computer’s machine code. If the object code is the same as the machine language, the computer can runthe program immediately after the compiler produces its translation. If the object code is notin machine language, other programs—such as assemblers, binders (联编程序), linkers, andloaders (加载程序)—finish the translation.Most computer languages use different versions of compilers for different types of computers or operating systems, so one language may have different compilers for personalcomputers (PC) and Apple Macintosh computers. Many different manufacturers often produceversions of the same。
