问题                 The Question that the Bit Torrent Procedure Kindles
    Bram Cohen was an unusual kid. While other first-graders were outside playing, he was writing computer code. By junior high, he could solve Rubik’s Cube in a few minutes. A college dropout, he went on to co-found a hacker’s convention in San Francisco. " I was always really weird," he says. Yet it was only two years ago, at age 27, that he learned why. Cohen says he has trouble examining his thoughts and making eye contact but has learned to control his symptoms using behavioral psychology. Now he has a new task: warding off accusations by the Hollywood film industry that a breakthrough piece of software he wrote is threatening the movie business the way Napster menaced—and subsequently revolutionized—the music world.
    Cohen is the author of a free program called Bit Torrent, which has been downloaded more than 20 million times and underpins a new generation of file-sharing technology. BitTorrent addresses a couple of the biggest problems of file sharing—that downloading bogs down when lots of folks access a file at once, and that some people download content but refuse to share with others on the network. BitTorrent eliminates the bottleneck by having everyone share little pieces of a file at the same time—a process techies call swarming. And the program prevents leeching since folks must upload a file while they download it. All this means that the more popular the content, the more efficiently it zips through the network—bad news if you’re a movie studio trying to hinder the trading of films like The Incredibles. Says Andrew Parker of the Web-tracking firm CacheLogic, " It has turned the download world on its head."
    Hollywood has good reason to be worried. BitTorrent downloads account for one-third of Internet traffic, according to CacheLogic. So-called tracker sites post links to movies, video games and episodes of TV shows, the content of which is then traded at express speeds. With more folks logging onto the Internet via broadband connections, online trading of movies and TV shows is surging. Downloads of feature films alone are up 175% in the past year, says BigChampagne. In response, the Motion Picture Association of America (MPA[A]) recently filed dozens of civil suits against tracker sites in the U. S. and Britain, as well as criminal complaints against sites in France. The industry is hoping that in a case scheduled for next month, the U. S. Supreme Court will rule against firms that produce file-sharing software, such as Morpheus and Grokster. Neither Cohen nor BitTorrent is named in the lawsuit, although an MPAA spokesman says Cohen is under examination for continuing to develop the software "and making it easy to steal copyright material".
The phrase "bogs down" (Line 7,Para.2) most probably means______.
选项 A、to stop
B、to get stuck
C、to lose content
D、to be in force
答案B
解析 语义理解题。第二段第二句提到BitTorrent解决了文件共享遇到的两个最大的问题，第一个是当许多人同时要提取同一个文件时，下载就会bog down。根据常识可知，当许多人同时下载一个文件时，下载速度会变得很慢，[B]“被困住”符合常识及上下文语境，故为答案。速度变得缓慢不堪并不意味着停止或丢失内容，排除[A]和[C];[D]“大批量下载”与语境矛盾，排除。
