A、St. John’ s University. B、Massachusetts Institute of Technology. C、University of California, Berkeley. D、Yale University. A细节题

Knowledge is free on the Internet at a small but growing number of colleges and universities. About 160 schools around the world now offer course materials free online to the public. Recent additions in the United States include projects at Yale, Johns Hopkins and the University of California, Berkeley.
    The Massachusetts Institute of Technology became an early leader with its Open Course Ware project, first announced in 2001. Free lecture notes, exams and other resources are published at ocw.mit.edu. Many exams and homework assignments even include the answers. The Web site also has videos of lectures and demonstrations.
    Today, Open Course Ware offers materials from 1,800 undergraduate and graduate courses. These range from physics and linear algebra to anthropology, political science—even scuba diving.
    Visitors can learn the same things M.I.T. students learn, but they receive no credit toward a degree. Some materials from a course may not be available, and the site does not provide contact with teachers.
    Still, M.I.T. says the site has had forty million visits by thirty-one million visitors from almost every country. Sixty percent of the visitors are from outside the United States and Canada.
    There are links to materials translated into Spanish, Portuguese, Chinese and Thai. Open Course Ware averages one million visits each month, and the translations receive half a million more.
