问题     While human achievements in mathematics continue to reach new levels of complexity, many of us who aren’ t mathematicians at heart (or engineers by trade) may struggle to remember the last time we used calculus (微积分).
    It’ s a fact not lost on American educators, who amid rising math failure rates are debating how math can better meet the real-life needs of students. Should we change the way math is taught in schools, or eliminate some courses entirely?
    Andrew Hacker, Queens College political science professor, thinks that advanced algebra and other higher-level math should be cut from curricula in favor of courses with more routine usefulness, like statistics.
    " We hear on all sides that we’ re not teaching enough mathematics, and the Chinese are running rings around us," Hacker says. "I’m suggesting we’ re teaching too much mathematics to too many people... not everybody has to know calculus. If you’re going to become an aeronautical (航空的) engineer, fine. But most of us aren’ t. "
    Instead, Hacker is pushing for more courses like the one he teaches at Queens College: Numeracy 101. There, his students of "citizen statistics" learn to analyze public information like the federal budget and corporate reports. Such courses, Hacker argues, are a remedy for the numerical illiteracy of adults who have completed high-level math like algebra but are unable to calculate the price of, say, a carpet by area.
    Hacker’ s argument has met with opposition from other math educators who say what’ s needed is to help students develop a better relationship with math earlier, rather than teaching them less math altogether.
    Maria Droujkova is a founder of Natural Math, and has taught basic calculus concepts to 5-year-olds. For Droujkova, high-level math is important, and what it could use in American classrooms is an injection of childlike wonder.
    " Make mathematics more available," Droujkova says. " Redesign it so it’ s more accessible to more kinds of people: young children, adults who worry about it, adults who may have had bad experiences. "
    Pamela Harris, a lecturer at the University of Texas at Austin, has a similar perspective. Harris says that American education is suffering from an epidemic of "fake math"—an emphasis on rote memorization (死记硬背) of formulas and steps, rather than an understanding of how math can influence the ways we see the world.
    Andrew Hacker, for the record, remains skeptical.
    "I’m going to leave it to those who are in mathematics to work out the ways to make their subject interesting and exciting so students want to take it," Hacker says. " All that I ask is that alternatives be offered instead of putting all of us on the road to calculus. "
What does the author say about ordinary Americans?
选项 A、They struggle to solve math problems.
B、They think math is a complex subject.
C、They find high-level math of little use.
D、They work hard to learn high-level math.
答案C
解析 推理题。原文第一段指出，大部分人根本不是数学家也不是工程师，他们可能很难记得上一次使用微积分是什么时候。由此可知，普通人很少用到像微积分这样的高层次数学，也就是说，像微积分这样的高层次数学实际上用处很小，故答案为C。A项利用struggle to进行干扰，文中说的是大部分人很难回想起上一次使用微积分的时间，而不是努力解决数学问题，故排除。B项利用complex进行干扰，文中说的是人类在数学方面的成就不断达到新的复杂程度，这属于客观描述，而非大部分美国人的看法，故排除。D项原文未提及，故排除。
