问题     By almost any measure, there is a boom in Internet-based instruction. In just a few years, 34 percent of American universities have begun offering some form of distance learning(DL), and among the larger schools, it’s closer to 90 percent. If you doubt the popularity of the trend, you probably haven’t heard of the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90,000 students, a statistic used to support its claim to be the largest private university in the country.
    While the kinds of instruction offered in these programs will differ, DL usually signifies a course in which the instructors post syllabi(课程大纲), reading assignments, and schedules on Websites, and students send in their assignments by e-mail. Generally speaking, face-to-face communication with an instructor is minimized or eliminated altogether.
    The attraction for students might at first seem obvious. Primarily, there’s the convenience promised by courses on the Net: you can do the work, as they say, in your pajamas(睡衣). But figures indicate that the reduced effort results in a reduced commitment to the course. While dropout rates for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weaknesses inherent in the setup. In a survey conducted for eCornell, the DL division of Cornell University, less than a third of the respondents expected the quality of the online course to be as good as the classroom course.
    Clearly, from the schools" perspective, there’s a lot of money to be saved. Although some of the more ambitious programs require new investments in servers and networks to support collaborative software, most DL courses can run on existing or minimally upgraded(升级)systems. The more students who enroll in a course but don’t come to campus, the more the school saves on keeping the lights on in the classrooms, paying doorkeepers, and maintaining parking lots. And there’s evidence that instructors must work harder to run a DL course for a variety of reasons, they won’t be paid any more, and might well be paid less.
What is the most striking feature of the University of Phoenix?
选项 A、All its courses are offered online.
B、Its online courses are of the best quality.
C、It boasts the largest number of students on campus.
D、Anyone taking its online courses is sure to get a degree.
答案A
解析 本题问的是凤凰城大学最显著的特征是什么，考查细节。第一段第三、四句指出，凤凰城大学的学位全部都是在网络教学的基础上授予的。A项“它的所有课程都是网络课程”与原文意思一致，故为答案。B、D两项文中未提及，可以排除。虽然文中提到凤凰城大学拥有9万名学生，声称是美国最大的私立大学，但是这些学生并不在校园中，而是通过远程教学上课，与C项“它自称校园中拥有最多的学生”矛盾，故排除。
