问题 What is the most striking feature of the University of Phoenix?
What accounts for the high drop-out rates for online students?
选项 A、There is no strict control over the academic standards of the courses.
B、The evaluation system used by online universities is inherently weak.
C、There is no mechanism to ensure that they make the required effort.
D、Lack of classroom interaction reduces the effectiveness of instruction.
答案C
解析 本题问“在网络在线学生中出现高退学阜的原因是什么?”文章第三段第三句指出“But figures indicate that the reduced effort results in a reduced commitment to the course．”(但是数据显示，付出的努力减少了，就会导致受这门课程约束程度的减少。)学生对课程付出的努力少了，课程对他们的约束也就会降低，自然就会出现高退学率。故[C]“没有保证学生会付出必要的努力的机制”正确。[A]“对课程的学术标准没有严格的控制。”文章中只提到网络教学的质量不如课堂教学，但是没有提及对网络课程学术标准的控制问题。[B]“网上大学使用的评估体系本身存在弱点。”文中提到，学生们似乎也了解网络课程所固有的缺点，但是这种缺点指的是网络教学的质量不如课堂教学高，而不是评估体系的问题。关于网上大学的评估体系文中没有明确提及。[D]“课堂互动的缺乏导致了教学有效性的降低。”从常识上讲，这是可能的。但是文章中没有提及这一点。
