单选题Cooperation is the common endeavor of two or more people to perform a task or reach a jointly cherished goal. Like competition and conflict, there are different forms of cooperation, based on group organization and attitudes. In the first form, known as primary cooperation, group and individual unite. The group contains nearly all of each individual's life. The rewards of the group's work are shared with each member. There is an interlocking identity of individual, group, and task performed. Means and goals become one, for cooperation itself is valued. While primary cooperation is most often characteristic of preliterate societies, secondary cooperation is characteristic of many modern societies. In secondary cooperation, individuals devote only part of their lives to the group. Cooperation itself is not a value. Most members of the group feel loyalty, but the welfare of the group is not the first consideration. Members perform tasks so that they can separately enjoy the fruits of their cooperation in the form of salary, prestige, or power. Business offices and professional athletic teams are examples of secondary cooperation. In the third type, called tertiary cooperation or accommodation, latent conflict underlies the shared work. The attitudes of the cooperating parties are purely opportunistic; the organization is loose and fragile. Accommodation involves common means to achieve antagonistic goals; it breaks down when the common means cease to aid each party in reaching its goals. This is not, strictly speaking, cooperation at all, and hence the somewhat contradictory term antagonistic cooperation is sometimes used for this relationship.

Temptation appears and some spouses consider it. Nowadays, cheating is on the rise. "You want something you can't get by behaving within the rules, and you want it badly enough, you'll do it regardless of any guilt or regret, and you're willing to run the risk of being caught. " That's how Ladd Wheeler, psychology professor at the University of Rochester in New York, defines cheating. Cheating represents the triumph of the "Brazen Rule" over the "Golden Rule", says Terry Pinkard, philosophy professor at Georgetown University in Washington D．C． "The Golden Rule says, Do unto others as you would have them do unto you.'The Brazen Rule says, Do unto others as they would do unto you if they were in your place. ' " Many experts believe cheating is on the rise. "We're seeing more of the kind of person who regards the world as a series of things to be manipulated． Whether to cheat depends on whether it's in the person's interest. " He does, however, see less cheating among the youngest students. Richard Dienslbier, psychology professor at the University of Nebraska in Lincoln, believes that society's attitudes account for much of the rise in cheating. "Twenty years ago, if a person cheated in college, society said:'That is extremely serious; you will be dropped for a semester if not kicked out permanently, ' " he says. "Nowadays, at the University of Nebraska, for example, it is the stated policy of the College of Arts and Sciences that if a student cheats on an exam, the student must receive an'F' on what he cheated on. That's nothing. If you're going to fail anyway, why not cheat?" Cheating is unethical, Pinkard says, whether it's massive fraud or failure to tell a store cashier you were undercharged． "You're treating other people merely as a means for your own ends. You're using people in ways they would not consent to. The cheater says, ' Let everybody else bear the burden, and I'll reap the benefits. '" Cheaters usually try to justify their actions, says Rohert Hogan, chairman of the psychology department at the University of Tulsa in Oklahoma． "They never think it's their fault. " Cheaters make justifications because they want to feel good about themselves, adds Wheeler. "They don't want to label themselves as a cheater. Also, they may be anticipating the possibility of getting caught, so they work on their excuse ahead of time. " The most common justifications, psychologists say, include: "I had to do it. " "The test was unfair. " "Everybody does it, and I have to cheat to get what's rightfully mine. " "The government wastes the money anyway. " "My wife (or husband) doesn't understand me, and we've grown apart. " Cheating is most likely in situation where the stakes are high and the chances of getting caught are low, says social psychologist Lynn Kahle of the University of Oregon in Eugene. In his study, a group of freshmen were allowed to grade their own tests, while secret, pressure sensitive paper indicated who changed answers. To raise the pressure, students were given an extremely high scores as the "average" for the test and told that those who failed would go before an inquiring board of psychologists. About 16 percent of the male students changed answers; among the females, about 30 percent cheated． Everybody cheats, a little, some psychologists say, while others insist that most people are basically honest and some wouldn't cheat under any circumstances. Despite the general rise in cheating, Pinkard sees some cause for hope: "I do find among younger students a much less tolerant attitude toward cheating. " Perhaps, he says, the upcoming generation is less spoiled than the "baby boom" students who preceded them—and therefore less self-centereD． "There seems to be a swing back in the culture. "
