问题    Now online provision is transforming higher education, giving the best universities a chance to widen their catch, opening new opportunities for the agile, and threatening doom for the slow and average. The roots are decades old. Britain’s Open University started teaching via radio and television in 1971. MIT and others have been posting lectures on the Internet for a decade.
   But the change in 2012 has been electrifying. Two start-ups, both spawned by Stanford University, are recruiting students at an astonishing rate for "massive open online courses" or MOOCs. In January, Sebastian Thrun, a computer-science professor there, announced the launch of Udacity. It started to offer courses the next month — a nanosecond by the standards of old-style university decision-making. In April, two of Mr. Thrun’s ex-colleagues launched a rival, Coursera. At first, it offered online courses from four universities. By August, it had signed up 1 million students, now boasting over 2 million. Harvard and MIT announced they would launch edX, a non-profit venture. Other schools have joined, too.
   One spur is economic and political pressure to improve productivity in higher education. The cost per student in the U.S. has risen at almost five times the rate of inflation since 1983. For universities beset by heavy debts, smaller taxpayer subsidies and a cyclical decline in enrollment, online courses mean better tuition, higher graduation rates and lower-cost degrees. New technology also gives the innovative a chance to shine against their rivals.
   MOOCs are more than good university lectures available online. The real innovation comes from integrating academic talks with interactive coursework, such as automated tests, quizzes and even games. Real-life lectures have no pause, rewind (or fast-forward) buttons; MOOCs let students learn at their own pace, typically with short, engaging videos. The cost of the courses can be spread over huge numbers of students. MOOCs enrich education for worldwide students, especially the cash-strapped, and those dissatisfied with what their own colleges are offering. But for others, especially in poor countries, online education opens the door to yearning for opportunities.
   Some of Europe’s best schools are determinedly unruffled. Oxford says that MOOCs "will not prompt it to change anything", adding that it "does not see them as revolutionary in anything other than scale". Cambridge even says it is "nonsense" to see MOOCs as a rival; it is "not in the business of online education". Such universities are likely to continue to attract the best (and richest) applicants who want personal tuition and the whiff of research in the air. For these places, MOOCs are chiefly a marketing opportunity.
   To compete head-on with established providers, MOOCs must not just teach but also provide credible qualifications. The vast majority of Coursera, Udacity and edX offerings do not provide a degree. This may be one reason for MOOCs’ high dropout rates. Another worry is that online tests are open to cheating and plagiarism. Peer grading even if honest, may be flawed.
The word "MOOCs" underlined in Paragraph 2 is______.
选项 A、a shortened version of "massive online open courses"
B、abbreviated from "massive open online courses"
C、another type of open classroom courses
D、equivalent to flipped classroom teaching
答案B
解析    词义界定。第二段“‘massive open online courses’or MOOCs”明确表明MOOCs的意义，or相当于“换言之”，取massive open online courses四个词的首字母就得到MOOC，加上courses是复数，所以加s，本意是“大规模开放性在线课程”。【知识拓展】在以前的“解析”与“知识拓展”中多次提到过词义界定可以依赖的线索，本题采用的线索是or的功能：同位语。另外，选项A的shortened version与选项B的abbreviated from不同，前者表示简缩版，如对长篇小说进行改编，变为精简故事；后者表示缩略语，如上一篇的UNESCO就来自United Nations Educational，Scientific and Cultural Organization。
