问题     It is 3 A. M. Everything on the university campus seems ghostlike in the quiet, misty darkness -- everything except the computer center. Here, twenty students untidy and blurred-eyed, sit transfixed at their consoles([计]挖制台), tapping away on the terminal keys. With eyes glued to the video screen, they tap on for hours. For the rest of the world, it might be the middle of the night, but here time does not exist. This is a world unto itself. These young computer "hackers" are pursuing a kind of impulse, a drive so consuming it overshadows nearly every other part of their lives and forms the focal point of their existence. They are compulsive computer programmers. Some of these students have been at the console for thirty hours or more without a break for meals or sleep. Some have fallen asleep on sofas or chairs in the computer center, trying to catch a few winks but hate to get too far away from their beloved machines.
    Most of these students don’t have to be at the computer center in the middle of the night. They aren’t working on assignments. They are there because they want to be -- they are irresistibly drawn there.
    And they are not alone. There are hackers at computer centers all across the country. In their extreme form, they focus on nothing else. They flunk(考试不及格)out of school and lose contact with friends; they might have difficulty finding jobs, choosing instead to wander from one computer center to another. They may even decline personal cleanliness.
    "I remember one hacker. We literally had to carry him off his chair to feed him and put him to sleep. We really feared for his health," says a computer science professor at MIT.
    Computer science teachers are now more aware of the implications of this hacker phenomenon and are
on the lookout for potential hackers and cases of computer addiction that are already severe. They know that the case of the hackers is not just the story of one person’s relationship with a machine. It is the story of a society’s relationship to the so-called thinking machines, which are becoming almost everywhere.
It can be reasonably inferred from the passage that ______.

选项 A、the "hacker" phenomenon exists only at university computer centers
B、university computer centers are open to every student
C、university computer centers are expecting outstanding programmers become the "hackers"
D、the "hacker" phenomenon is partly attributable to the deficiency of the computer centers

答案B

解析 由文章第一段可知此情景是发生在大学计算机中心,由第三、四段可知:这些学生成绩不好,他们没日没夜地在计算机中心,所以可知大学计算机中心是对所有学生开放的,所以选B)。由文章最后一句:这种现象到处可见,可知A)不对;由文章最后一段的第一句:他们越来越意识到黑客的意义并为越来越严重的沉迷于计算机的现象而担心,所以C)不对。
