     A is for always getting to work on time.

     B is for being extremely busy.

     C is for the conscientious ( 勤勤恳恳的 ) way you do your job.

     You may be all these things at the office, and more. But when it comes to getting ahead, experts say,

the ABCs of business should include a P, for politics, as in office politics.

     Dale Carnegie suggested as much more than 50 years ago hard work alone doesn't ensure career

advancement. You have to be able to sell yourself and your ideas, both publicly and behind the scenes.

Yet, despite the obvious rewards of engaging in office politics-a better job, a raise, praise-many people

are still unable-or unwilling-to play the game.

     People assume that office politics involves some manipulative (工于心计的) behavior, says Deborah

Comer, an assistant professor of management at Hofstra University. But politics derives from the word

'polite'. It can mean lobbying(游说) and forming associations. It can mean being kind and helpful, or even

trying to please your superior, and then expecting something in return.

     In fact, today, experts define office politics as proper behavior used to pursue one's own self-interest

in the workplace. In many cases, this involves some form of socializing within the office environment-not

just in large companies, but in small workplaces as well.

     The first thing people are usually judged on is their ability to perform well on a consistent basis, says

Neil P. Lewis, a management psychologist. But if two or three candidates are up for a promotion, each

of whom has reasonably similar ability, a manager is going to promote the person he or she likes best. It's

simple human nature.

     Yet, psychologists say, many employees and employers have trouble with the concept of politics in

the office. Some people, they say, have an idealistic vision of work and what it takes to succeed. Still

others associate politics with flattery (奉承), fearful that, if they speak up for themselves, they may

appear to be flattering their boss for favors.

     Experts suggest altering this negative picture by recognizing the need for some self-promotion.

1. Office politics (Line 2, Para. 4) is used in the passage to refer to ______.

A. the code of behavior for company staff

B. the political views and beliefs of office workers

C. the interpersonal relationships within a company

D. the various qualities required for a successful career

2. To get promoted, one must not only be equal to his job but ______.

A. give his boss a good impression

B. honest and loyal to his company

C. get along well with his colleagues

D. avoid being too outstanding

3. Why are many people unwilling to play the game (Line 4, Para. 5)?

A. They believe that doing so is impractical.

B. They feel that such behavior is unprincipled.

C. They are not good at manipulating colleagues.

D. They think the effort will get them nowhere.

4. It is the author's view that ______.

A. speaking up for oneself is part of human nature

B. self-promotion does not necessarily mean flattery

C. hard work contributes very little to one's promotion

D. many employees fail to recognize the need of flattery
