问题     It was supposed to be a quick diversion, Katie Inman told herself last week as she flipped open her laptop. She had two tests to study for, three problem sets due, a paper to revise. But within minutes, the MIT sophomore was drawn into the depths of the Internet, her work put aside.
"I had just closed Facebook, but then I reopened it. It’s horrible," said Inman, a mechanical engineering major. "I would type a sentence for my paper, and then get back on Facebook."
    Desperate for productivity, Inman did something many of her classmates at one of the most wired campuses would find inconceivable. She installed a program that blocks certain websites for up to 24 hours. No social networking. No e-mail. No aimless surfing.
    While Inman took matters into her own hands, some MIT professors are urging college leaders across the country to free students from their binding to technology. Over the past decade, schools raced to connect students to the Internet—in dorms, classrooms, even under the old oak tree. But now, what once would have been considered abnormal is an active point of discussion: pulling the virtual plug to encourage students to pay more attention in class and become more skilled at real-life social networking.
    "I have been a bit suspicious about the value of making an entire campus wireless," said Lawrence Bacow, former chancellor of MIT, where he was a professor when it began wiring all classrooms in the mid-1990s. "It seems like everyone is always plugged in and always distracted."
    At MIT, where the Internet is accessible even near the banks of the Charles River, students’ eyes obsessively wander, midconversation, down to laptops and cellphones, checking for missed updates from friends.
    In class, professors complain about students trading stocks online, shopping for Hermes scarves, showing one another video clips on YouTube—leading some faculty to call for the unwiring of all lecture halls.
    "Students are totally shameless about how they use their computers in class," said David Jones, an MIT professor. "I imagine having a Wi-Fi jammer in my lecture halls to block access to distractions."
    While MIT has yet to unwire a single lecture hall, some law schools have in recent years blocked wireless access in classrooms to keep students engaged in Socratic discussions instead of their classmates’ Groupon and eBay activities.
    Since digital monsters have come, can hunters be far behind?
According to this passage, students at MIT are notoriously busy________at class.

选项 A、getting wired instead of listening
B、taking a lot of notes using laptops
C、updating the software of their laptops
D、getting involved in discussions

答案A

解析 文章第六段和第七段主要描述了学生上课时的种种不良表现:学生的眼球离不开笔记本电脑或手机,看是否有最新的信息。老师抱怨学生上课时炒股、购物或交流视频。这些现象说明学生上课时关注的不是教学内容,而是自己的网络世界。
