Is this happening in your neighborhood? Children，notebook computers stuck under their arms，await the yellow bus for the trip to middle schoo1.On the surface，the question of computers in schools is a no-brainer.It would be strange to insist that today‘s technology shouldn’t be used to make the classroom experience more individualized，more effective，more immediate，more exciting.Computers have been in schools more than 20 years—and probably even done some good.

But the idea of a personal computer as a necessary daily tool for every American grammar school pupil is altogether a different thing.Beware the superficially attractive vision of 10-year-olds doing most of their work—and homework—on a computer.It‘s another illusory silver bullet that promises to solve a11 of society’s ills through technology.Regardless of whether parents or taxpayers buy the machinery，it‘s a bad policy.

Determining the proper role of computers in schools is too important to be left to computer suppliers and educators.An educated public with clear and realistic expectations needs to help determine the right track for technology.

Educators forever seem to seek the ultimate in curricular or teaching tools.They are always preoccupied with innovation—junior high school，new math，whole language，open classrooms and mastery learning，to name a few.Some ideas turned out well and over time have earned permanent positions in our education systems.Others reflected change for change‘s sake and wound up in the trash bin，Where they belong.

Exactly what is to be solved with computers in schools? Are we looking to improve instructional capacity and flexibility? Are we trying to make teachers and aides more productive by letting students take advantage of programmed learning tools? This all sounds good，and much has been accomplished with computer assisted instruction.

But that‘s not the same as making the computer a symbol of well-tempered educational policy.There’s danger in the message that a child is not fully educated if he or she can‘t surf the World Wide Web skillfully，move around in Windows or the Finder，use a word processing program，or program in Logo or Basic.

These skills can be learned outside the classroom.Worse，the time it takes students to acquire them is time stolen from the legitimate teaching schedule—and that‘s a bad trade.

And what kind of computers should be purchased? We‘re not talking brand names.Most school systems don’t have the money to replace PCs or Macs on the two-to three-year cycle that shifting technologies demand.On the other hand，$ 2，500一the cost of just one computer—invested in books for the school library produces an asset that has，shall we say，a longer shelf life.

And who changes the factory culture of schoolrooms to allow computers to be more effective? And who teaches the teachers? These are the really tough issues—the ones that more hardware won‘t solve.

Children are best served when schools contribute to shaping the solid foundations on which their future will be built.The student who can read with curiosity and understanding，who has mastered basic mathematical concepts，who can evaluate ideas critically，is the one schools should aim to produce.

[A]the computer is too expensive a luxury for school pupils

[C]it takes too much time which might has been spent on regular courses

[D]teachers should be taught how to teach computer skills

5. The author‘s attitude towards the present way of teaching computer in schools is____.

[A]critical [B]objective

[C]positive [D]optimistic

参考答案：

1. [C]意为：它占用了太多的时间，而这些时间本来可以用于正常课程。 参阅第七段和最后一段。

2. [A] 根据下一句的意思，该词应理解为“无须思考的问题”。

3. [D] 第三段指出，决定计算机在学校中应该起什么作用是一件重要的事，不能仅交由计算机供应商和教育工作者来定，公众也应该有发言权。

4. [C] 最后一段指出，学校的根本任务是为学生的未来打下坚实的基础，学校旨在培养的学生应是具有好奇心和理解力，能掌握数学基本概念。并能对现存的一些观念进行独立评价。言外之意，由于盲目地进行计算机教育，这些基础容易被忽视。

5. [A]意为：批评的。 文章从第二段起就开始对目前的计算机教学提出了批评，并在最后一段强调指出它对培养学生基本能力的不良影响。

某学业成就测验由100道正误题组成，每题1分。如果要从统计上（99%的把握）排除猜测作答的情形，考生正确回答的题曰数量至少应该是

A.59题
B.60题
C.62题
D.63题

答案：C

解析：

此题考查的是二项分布的应用。此题n= 100，p=0.5，g=0.5，p=q，np= 20>5，故此二项分布接近正态分布，这时二项分布的x变量（即成功的次数）具有如下性质， 经过计算本题中 也就是说，如果考生随机猜测作答，答对的平均题数是50，标准差为5。据正态分布概率，当Z= 2.33时，该点以下包含了全体的99%（注意这是单侧检验），如果用原始分数表示，则为 如果本题要求的95％的把握排除猜测作答的可能性，那么当Z=1.645时，该点以下包含了全体的95%（单侧检验），那么用原始分数表示，则为。

下列关于《中华民国宪法》(1946年)的表述，正确的有（　　）。
A.基本精神与“五五宪草”一脉相承
B.规定了“五院制”的政府组织形式
C.实行总统制的政治体制
D.罗列各项民主权利自由，比以往任何宪法规定得都充分

答案：A,D

解析：

【精解】《中华民国宪法》(1946年)的基本精神与《中华民国训政时期约法》和“五五宪草”的基本精是一致的。故选A项。需要注意：虽然《中华民国宪法》(1946年)与《中华民国训政时期约法》一脉相承，但是这种承继仅限于基本原则与基本精神，并不意味着具体的继承，且“五院制”这种具体规定早在《中华民国训政时期约法》时就已作出规定，故排除B项。《中华民国宪法》(1946年)的内容特点之一就是在政权体制的规定上不伦不类，既非总统制，又非国会制、内阁制。实际上是用这种矛盾的条文掩盖蒋介石个人专制统治的本质。故排除C项。《中华民国宪法》(1946年)罗列人民各项民主自由权利，尽管都属于形式上的东西，但是不能否认，这部宪法对这些权利的规定确实比以往任何宪法文件都充分，只不过这些权利的规定过于抽象，且在具体实施上受到临时性特别法规的限制，故选D项。
