Questions 6~10 are based on the following passageThe strong tie between organized sports and the competitive ethic ( 准则）has given greater importance to men ’s sp orts than to women ’s, since man ’s role in the United States is viewed as more competitive and aggressive than woman’s. As one high school teacher stated more than two decades ago: “Our culture does not require girls to compete against each other in physica l activity to achieve the acceptable female image. Our culture does require boys to do so.” During the last fifteen years, however, this has been changing, and a stronger emphasis on equality for women has emerged in all facets (方面) of American life, including organized sports. High schools and colleges have been urged to give more emphasis to women’s sports and to spend more money on them. In fact, laws governing equality have required many schools to do so. It is still true, however, that most Americans believe men’s organized sports are more important than women’s. In high school, and to a lesser extent in college, males earn popularity and recognition through competing in organized sports, while females often earn these same things by being cheerleaders. The cheerleader does not compete. Rather, she is part of a group of pretty girls who lead the people watching football or basketball games in cheering for the school team, which is composed of competitive young men.The diffe rence in roles between the males and females at major sports events reflects differences in traditional roles later in life, when men are expected to compete for economic success and women are supposed to give men emotional support as wives and homemakers. What has brought greater importance to men’s sports? A．The strong tie between sports and competition. B．The competitive and aggressive nature of men. C．The improper teaching of high school education. D．The competition against others in physical activity.
