问题      There was a time when parents who wanted an educational present for their children would buy a typewriter, a globe or an encyclopedia set. Now those  【21】______   seem hopelessly old-fashioned: this Christmas, there were a lot of  【22】______   computers under the tree.  【23】______   that computers are their key to success, parents are also frantically insisting that children 【24】______   taught to use them on school— as early as possible.
      The problem for schools is that when it  【25】______   computers, parents don’t always know best. Many schools are  【26】______   parental impatience and are purchasing hardware without  【27】______   educational  planning so they can say,"OK, we’vr moved into the computer age. "Teachers   【28】______   themselves  caught in the middle of the problem — between parent pressure and   【29】______   educational decisions.
      Educators do not even agree  【30】______   how computers should be used. A lot of money is going for computerized educational materials  【31】______   research has shown can be taught  【32】______   with pencil and paper. Even those who believe that all children should  【33】______   to computer warn of potential  【34】______   to the very young.
    The temptation remains strong largely because young childrern  【35】______   so well to computers. First graders have been  【36】______   willing to work for two hours on math skills. Some have an attention span of 20 minutes.  【37】______   school ,however, can afford to go into computing, and that creates  【38】______   another problem: a division between the have’s and have-not’s. Very few parents ask   【39】______   computer instruction in poor school districts, 【40】______   there may be barely enough money to pay the reading teacher.

选项 A、already
B、of course
C、in addition
D、yet
答案D
解析 本小题要求根据上下文的内容选择填入空白处在意义相结构上都正确的词语。already意为“已经”，of course意为“当然”，in addition意为“除此之外还……”。而yet的用法比较复杂，应注意以下几点：1)用在否定句中，表示“还(没有)”，如I’m not quite clear yet about this question．(我还不太明白这个问题。)2)用在疑问句中，表示“已经”，如Have you finished it yet?(你已经做完了吧?)3)表示“仍然”，“还在”，“还得”，如Father rose early and is working yet．(父亲起得很早，现在还在工作。)4)和比较级连用，表示“更加”，如This is bad；that is yet worse．(这个不好，那个更糟。)5)和another或more连用，表示“还有”如I’vr had yet another bill．(我还有一份账单。)故应选D 。
