问题     Predictions of large populations of robots in industry have yet to come true. For a decade or more, manufacturers of big robots have explained how their machines can make industry more competitive and productive. The market for【C1】______robots is now oversupplied, and the driving force of the robotics (机器人技术) revolution is【C2】______to be with makers of machines that handle a few kilos at most.
    "Heavy-robot manufacturers are in some difficulty【C3】______finding customers. They are offering big【C4】______just to get in the door. There has been a【C5】______growth everywhere in the numbers of ro-bots, so we have to admit we are either deceiving【C6】______or that the market is slowly growing, " said John Reekie, Chairman of Colne Robotics. " The following things must happen【C7】______the robotics revolution to occur. We must achieve widespread robot literacy (文化) ,【C8】______there has been a computer literacy program, there must be a robot literacy campaign. We must also【C9】______not just a cut in, but a collapse of robot prices.【C10】______, some kind of artificial intelligence needs to be【C11】______"
    Colne makes educational robots and machine tools. It is small【C12】______with companies like ASEA or Fujitsu Fanuc. But Colne with others and departments in universities such as Surrey, Manchester, and Durham possess an advantage【C13】______the giants. The big companies sell very expensive【C14】______to businesses with expert knowledge in automation. The【C15】______companies make robots for teaching people, and now they have realized there is a need for small,【C16】______robots that they can meet.
    The little companies either bring their educational machines【C17】______an industrial standard or design from scratch (从头做起)- One technique that they all adopt is to choose【C18】______components where possible. The major cost of making【C19】______their models is the electronics, which will fall in price. There is【C20】______scope for reductions in mechanical costs. The use of standard parts, which are easily replaced, should give these robots a mechanical life of something in the order of five years.
【C3】
选项 A、to
B、with
C、over
D、in
答案D
