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.
According to paragraph 3, students choose MOOCs for the following reasons EXCEPT______.
选项 A、earning a certificate
B、improving job-related skills
C、meeting their interest in the subjects
D、exchanging ideas with students worldwide
答案A
解析 细节题。根据第三段第一句可知，学生们根据自己的兴趣和职业目标来选择课程。所以选项B(提高工作相关技能)和选项C(满足相关兴趣)是选择课程的理由。根据第三段第二句可知，还有一些人利用论坛来与世界各地的知识同行建立联系，所以选项D(与全世界的学生相互交流思想)也是选择课程的理由。选项A(为了获得证书)不是选择课程的理由，第一段第一句就说明了只有5％的学生完成课程并获得证书，故答案为A。
