问题     You have probably heard some of the hoopla(大肆宣传)about elite universities offering free online courses through Coursera. In just the past few weeks, Coursera has added 12 universities to its lineup, including Princeton, Duke and Johns Hopkins.
    The company’s website says its goal is to "give everyone access to the world-class education that has so far been available only to a select few," and much of the news coverage has focused on how this will democratize learning. Two weeks after Coursera announced its initial round of partnerships, Harvard University and the Massachusetts Institute of Technology announced a plan to invest $ 60 million in a similar course platform called edX, and a third company, Udacity, announced that it too would join the fray.
    Despite near universal enthusiasm for such projects, it’s important to take a few steps back. First, although the content is free now, it’s unlikely that it will remain that way for long. According to Coursera’s contracts, both the company and the schools plan to make a profit—they just haven’t figured out the best way to do that yet. But more important, I am concerned that computer-aided instruction will actually widen the gap between the financially and educationally privileged and everyone else, instead of close it.
    In terms of learning on the college level, the Department of Education looked at thousands of research studies from 1996 to 2008 and found that in higher education, students rarely learned as much from online courses as they did in traditional classes. In fact, the report found that the biggest benefit of online instruction came from a blended learning environment that combined technology with traditional methods, but warned that the uptick had more to do with the increased amount of individualized instruction students got in that environment, not the presence of technology. For all but the brightest, the more time students spend with traditional instruction, the better they seem to do.
    Supporters of online learning say that all anyone needs to access a great education is a stable Internet connection. But only 35% of households earning less than $25,000 have broadband access to the Internet, compared with 94% of households with income in excess of $ 100,000. In addition, according to the 2010 Report on Mobile Access, only half of black and Latino homes have Internet connections at all, compared with almost 65% of white households. Many blacks and Latinos primarily use their cell phones to access the Internet, a much more expensive and less-than-ideal method for taking part in online education. In short, the explosion of this type of educational instruction, though free now, may leave behind the students who need education the most.
    It’s not hard to understand why the chance to watch lectures, pass tests and even get a formal certificate from an elite school would stir excitement. But as the recently released report on the American Dream makes clear, a four-year college degree is the only type of educational intervention that promotes upward mobility from the lower-middle class. If we really want to democratize education, finding creative ways to realistically open up colleges to different communities will do more to help than a model that is more beneficial for students who are already wealthy, academically prepared and highly motivated. We ought to make sure that everyone has access to the same opportunities, or we will further widen the opportunity gaps we mean to close.
Which of the following is NOT the reason why computer-aided instruction will actually widen the educational gap?
选项 A、Both the company and the schools which provide free online courses now plan to make a profit in the long run.
B、The presence of technology in online instruction won’t help college students as much as traditional classes.
C、Household income levels and races result in different Internet connection statuses.
D、It’s very unrealistic to provide online courses to people from different communities.
答案D
解析 事实细节题。作者在文章第二段提到了公司和学校都想在网络课程中获利；第四段提到学生们在网络课程中学到的不如在传统课堂中学到的多；第五段提到不同收入、人种的家庭对网络的拥有率不同。这些都是网络授课事实上会加大教育差距的原因。但文中并未提到为不同群体提供网络课程是不现实的，故D)为正确答案。
