1 passage A

The central processing 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. 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).

— 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。,每题1分，共5分）

task of developing programs for the solution of computational problems is

referred to as programming. Computer programming is the process of planning

and creating a sequence of steps for a computer to follow. In general, this

process will help us resolve a problem, which is either too tedious or

difficult to work out otherwise . So programming is breaking a task down

into small steps.

Programming is sometimes contrasted with coding. Coding generally

refers to the writing of programs for given program specification, while

programming includes the task of preparing the program specification as well

as that of writing the program. The text of a program is sometimes referred

to as code, and lines of program text are referred to as lines of code,

especially in the case of machine-language programs. The term coder is used

to describe a person engaged exclusively in implementing program

specifications prepared by others.

What's actually involved in programming - the actual process of writing

programs? Here's a quick overview of the process:

· Write a program. · Compile the program. · Run the

program. · Debug the program.

A. Write a program. B. Debug the program.

C. Print the program. D. Compile the program.
