单选题 .  "We are not about to enter the Information Age, but instead are rather well into it." Present predictions are that by 1990, about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related. In 1980, only twenty-one percent of all American high schools owned one or two computers for student use. In the fall of 1985, a new study showed that half of United States secondary schools have fifteen or more computers for student use. And now educational experts, administrators, and even the general public are demanding that all students become "computer-literate". By the year 2000 knowledge of computers will be necessary in over eighty percent of all occupations. Soon those people not educated in computer use will be compared to those who are print-illiterate today.
    What is "computer literacy"? The term itself seems to imply some degree of "knowing" about computers, but knowing what? The present opinion seems to be that this should include a general knowledge, of what computers are, plus a little of their history and something of how they operate.
    Therefore, it is important that educators everywhere take a careful look not only at what is being done, but also at what should be done in the field of computer education. Today most adults are able to use a motor car without the slightest knowledge of how the internal combustion engine works. We effectively use all types of electrical equipment without being able to tell their histories or to explain how they work.
    Business people for years have made good use of typewriters and adding machines, yet few have ever known bow to repair them. Why, then, attempt to teach computers by teaching how or why they work?
    Rather, we first must fix our mind on teaching the effective use of the computer as the tool is.
    "Knowing how to use a computer is what's going to be important. We don't talk about 'automobile literacy'. We just get in our cars and drive them."1.  In 1990, the number of jobs having nothing to do with computers in the United States will be reduced to?
【正确答案】 B
【答案解析】[参考译文] “我们不是将要进入信息时代，而是置身其中的感觉相当好。”目前的预测是，到1990年，在美国大约3000万的工作或大约30%的工作市场将和电脑相关。1980年，所有美国高中只有21%的学校拥有一台或两台供学生用的电脑。而在1985年秋季，一项新的研究表明，美国一半的中等学校拥有十五台或者更多的供学生用的电脑。现在教育专家、行政人员、甚至普通大众正要求所有学生会使用电脑。到2000年，电脑知识将在超过80%的职业中成为必然要求。很快那些不会使用电脑的人将会被比作今日的“打字文盲”。
   “电脑读写能力”是什么?这个术语本身暗示某种程度上与电脑有关，但是知道什么呢?时下的观点好像是，它应该包括对电脑是什么有大概了解，另外知道一些电脑的历史以及知道电脑运行方面的一些知识。
   因此，每个地方的教育者不仅要留心观察正在做的事情，而且要注意在电脑教育领域什么应该做。今天，大部分成年人在几乎不知内燃机如何运作的情况下能够驾驶一辆摩托车。在无法讲出它们的历史或解释它们如何工作的情况下，我们也能够有效地使用各种电器设备。
   生意人已经充分利用打字机和加法机很多年了，但很少有人知道怎样维修它们。那么为什么试图教电脑要通过教它们内部构造以及电脑运行的原因呢?
   更确切地说，首先我们必须把注意力放在教授电脑的有效使用上，正如工具一般。
   “知道怎样使用电脑将会变得重要。我们不是在讨论‘汽车读写能力’。我们只需上车并且驾驶就可以。”
细节题。根据题干中的时间In 1990可定位至文章第一段第二句“Present predictions are that by 1990, about thirty million jobs in the United States, or about thirty percent of the job market, will be computer-related.”即“目前的预测是，到1990年，在美国大约3000万的工作或大约30%的工作市场将和电脑相关。”换句话说，就是7000万的工作将和电脑没有关系，因此B选项为正确答案。
