问题 When MIT put their course content online in 2002, they were expecting their site to be one of the most popular sites around the world. [br] MIT has been in the leading position so far by offering free materials for as many as ______.

选项

答案 1,800 courses

解析 由题干中MIT可定位到第三个小标题下第三段第二句MIT has led the way, but now that MIT has made all of its 1,800 courses available...题干中in the leading position与原句led the way相对应。[精析] 此处要求填入表数量性的短语与题干中as many as搭配。根据原句可知,MIT在提供免费课程资料方面居第一位,为1,800门课程提供了免费资料。故1,800 courses满足题干要求,即为答案。
