Passage A
The central processing unit (CUP) 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, which its speed and capacity have increased tremendously. Indeed, these changes have resulted in micro-Computers that are small enough to fit on your desk and your lap. The CPU comprise 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 comparison. 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.
(二) 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) (15%)
1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( )
