问题     When today’s college graduates get together for a reunion someday, they may decide to do it by computer. That’s because right now, nearly one in five college students takes at least one class online, according to a new survey.
    For professors, the growth of e-learning has meant a big shift in the way they deal with students.
    Take professor Sara Cordell of the University of Illinois-Springfield: Her day doesn’t end at 6 p.m., as it does for some college professors.
    Cordell sits at her computer in her campus office to chat with a half-dozen students gathered in front of their screens: One is in Tennessee, another in California’s central valley, another in Ohio. They’re all here to talk about Thomas Hardy’s 19th-century novel Tess of the D’Urbervilles.
    Cordell has a microphone hooked up to her PC, and her students listen from home. All but one of them type their responses, which appear in chat-format on Cordell’s screen.
    The process looks kind of awkward—the natural flow of a regular class is missing, as responses arrive onscreen in a digital flood. But at second glance, there’s something else here not seen in a regular college class: All of the students are paying attention and all are engaged.
    Cordell, who is in her 50s, has been teaching offline for 25 years; online for four. She said she was initially skeptical about how meaningful an English course could be online. But now she’s a convert. Online classes conducted in real time have a special kind of immediacy, Cordell said.
    "They’re right there. They’re listening. And they like talking to each other, typing to each other. That, I think, is a big attraction, because they get to engage real time with the other students as much as with me," Cordell said.
    After two hours of discussion, Cordell signs off. But the class actually never goes to sleep. The students, including a mother of six, will keep the conversation going. This is known as the asynchronous part of the class, and it happens on an online education content management system, where written assignments are posted.
    That means the work never stops—and many instructors say teaching an online class is more work. [br] What happens in the asynchronous part of the class?
选项 A、The students hand in their written assignment.
B、The students keep discussing without the teacher.
C、The students take turns to play the role of the teacher.
D、The students sign off after they finish their homework.
答案 B
解析 这一题同样考查代词的所指。倒数第2段最后一句中的this应该是指上两句提到的内容，概括上两句的内容可以知道，B与之最为相近，为本题答案。
