Passage 1
The next time the men were taken up onto the deck, Kunta made a point of looking at the man behind him in line, the one who lay beside him to the left when they were below. He was a Serer tribesman much older than Kunta, and his body, front and back, was creased with whip cuts, some of them so deep and festering that Kunta, felt badly for having wished sometimes that be might strike the man in the darkness for moaning so steadily in his pain. Staring back at Kunta, the Serer’s dark eyes were full of fury and defiance. A whip lashed out even as they stood looking at each other--this time at Kunta, spurring him to move ahead. Trying to roll away, Kunta was kicked heavily in his ribs. But somehow he and the gasping Wolof managed to stagger back up among the other men from their shelf who were shambling toward their dousing with bucke

[单项选择]According to Scott Adams, creator of the comic strip (系列漫画) Dilbert, the annual performance review is "one of the most frightening and weakening experiences" in every employee"s life. Adam"s stories and comic figures poke fun at the workplace, but his characterization of people"s feelings about the annual performance review has its serious side. Although a recent study of 437 companies indicates that effective annual performance reviews can help raise profits, most employees of those companies hate them. In theory, annual performance reviews are constructive and positive interactions between managers and employees working together to attain maximum performance and strengthen the organization. In reality, they often create division, undermine morale, and spark anger and jealousy. Thus although the object of the annual performance review is to improve performance, it often has the opposite result. A programmer at an IT firm was stunned to learn at her annual performance review that she was denied a promotion because she wasn"t a "term player". What were the data used to make this judgment She didn"t smile in the company photo. Although this story might sound as if it came straight out of Dilbert, it is a true account of one woman"s experience. By following a few ideas and guidelines from industry analysis, this kind of ordeal can be avoided: To end the year with a positive and useful performance review, managers and employees must start the year by working together to establish clear goals and expectations. It may be helpful to allow employees to propose a list of people associated with the company who will be in a good position to assess their performance at the end of the year; these people may be co-workers, suppliers, or even customers. Goals should be measurable but flexible, and everyone should sign off on the plan. By checking employees" progress at about nine months, managers can give them a chance to correct mistakes and provide guidance to those who need it before the year is out. When conducting the review, managers should highlight strengths and weaknesses during the past year and discuss future responsibilities, avoiding punishment or blame. In short, when employees leave their performance reviews, they should be focusing on what they can do better in the year ahead, not worrying about what went into their files about the past.The word "ordeal" in Paragraph 3 probably refers to ______.
A. likelihood of promotion
B. depressive experience
C. poor performance
D. unrealistic expectation
