问题     Human beings have always had an ability to attend to several things at once. (78) Nor is electronic multitasking entirely new: We’ve been driving while listening to car radios since they became popular in the 1930s. but there is no doubt that multitasking has reached a kind of warp speed in the era of Web-enabled computers, when it has become routine to conduct several IM (及时通讯) conversations, watch TV and use the computer all at once.
    But what’s the impact of this media consumption? And how are these multitasking devices changing how kids learn, reason and communicate with one another? Social scientists and educators are just beginning to deal with these questions, but the researchers already have some strong opinions.
    (79) Although multitasking kids may be better prepared in some ways for today’s fast-paced work places, Many scientists are positively alarmed by the trend. Kids that are instant messaging while doing homework, playing games online and watching TV, aren’t going to do well in the long run.
    On the positive side, multitasking students tend to be extraordinarily good at finding and using information. And probably because modem childhood centers around visual (视觉的) rather than print media, they are especially skilled at analyzing visual data and images.
    Many educators and psychologists say parents need to actively ensure that their teenagers break free of uncontrollable engagement with screens and spend time in the physical company of human beings--a growing challenge not just because technology offers such a handy option but because so many kids lead highly scheduled lives that leave little time for old-fashioned socializing and family meals. Indeed, many teenagers and college students say overcommitted(任务过量的) schedules drives much of their multitasking.
    Just as important is for parents and educators to teach kids that it’s valuable, even essential, to occasionally slow down, unplugs and take time to enjoy life beyond the screen.
The expression "warp speed" in the first paragraph is closest in meaning to ______.
选项 A、low speed
B、too much time alone
C、high speed
D、steady speed
答案C
解析 本题考查考生对特定语境下的词汇的理解。根据文意，“毫无疑问，在互联网时代，多任务处理已经达到了______，现在，人们已习惯于同时开多个即时聊天窗口，边看电视边玩电脑。”可知，一个人同时做这些事情的时候，速度是很快的。因此选择C，high speed。
