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.
