表示“a与b的两数和的平方”的代数式是（ ） A . a2+b2 B . a+b2 C . a2+b D . （a+b）2 答案：D2、阅读下面短文，根据第1至第3小题的具体要求，简要回答问题。 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 as 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 being dedicated to 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 Comeran, assistant professor of management at Hofstra University. “But politics comes from the word ‘polite’. It can mean persuading 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 seek one’s own self-interest in the workplace. In many cases, this involves some form of getting along with others within the office environment—not just in large companies, but in small workplaces as well. Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people , they say, have an idealistic idea 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 changing this negative picture by recognizing the need for some self promotion. 1．What does it mean by saying “many people are still unable—or unwilling—to ‘play the game’”?（回答词数不超过15个） 2．According to today’s experts, what is office politics?（回答词数不超过12个） 3．What’s the main idea of the passage?（回答词数不超过8个）
