Passage A The central proce吉sing 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.

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。15分，每题3分) 36.With the development of computer,the physical size of the CPU has often become bigger and bigger.
