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’ve 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 children  【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 haves and have-nots. Very few parents ask  【39】______    computer instruction in poor school districts,  【40】______    there may be barely enough money to pay the reading teacher.
【38】
