问题    Out of all the students who enroll in a massive open online course (MOOC) , only about 5 percent complete the course and receive a certificate accomplishment. This statistic is often cited as evidence that MOOCs are fatally flawed (有缺陷的) and offer little educational value to most students. Yet more than80 percent of students who fill out a post-course survey say they met their primary objective. How do we look at these two facts?
   We ’ re used to focusing on completion rates in higher education, but they’ re not the only—or even the most meaningful—indicator of engagement in open online courses. With no cost to enroll, no punishment for dropping out, and little reward for actually earning a certificate, MOOCs are fundamentally different from traditional classes—and students use them in fundamentally different ways.
   Data from more than 1. 8 million students enrolled in 36 MOOCs offered by the University of Pennsylvania show that students treat MOOCs like a buffet (自助餐) , sampling the material according to their interests and career goals. Some are curious about the subject matter and just watch one or two video lectures: others use the discussion forums to connect with their intellectual peers around the world. Of all enrolled students, nearly 60 percent watch at least one video, complete at least one assignment, or post at least once in a forum.
   So focusing on the tiny fraction of students who complete a MOOC is misguided. The more important number is the 60 percent engagement rate. Students may not finish a MOOC with a certificate of accomplishment, but the courses nonetheless meet the educational goals of millions.
What do we learn about MOOCs from paragraph 1?
选项 A、There seems to be conflicting statistics about MOOCs.
B、It turns out that MOOCs have failed people’ s expectations.
C、Most students find it hard to judge the value of MOOCs.
D、The educational value of MOOCs is well acknowledged.
答案A
解析 推理题。根据第一段第一句和第三句可知，作者给了我们两个统计数据5％和80％，分别代表了人们对大型开放式网络课程不同的、相反的评价。所以选项A(关于慕课有相互冲突的统计数据)正确。选项B(结果证明慕课辜负了人们的期望)和第一段第三句的意思不符。选项C(大部分学生觉得很难判断慕课的价值)与文章内容不符，文中第一段第三句给出了正面评价。选项D(慕课的教育价值被广泛认可)和第一段第二句意思不符，故答案为A。
