共享题干题 （一） Robot 阅读材料，回答下列的问题。（1）The most sophisticated ( 先进的 ) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly puter control software, are considered to be generally less advanced in Japan than in America or Europe.（2）Although industrial robots were originally developed as devices for simply handling objects, today their monest uses are for more skilled work like welding ( 焊接 ) , spray-painting and assembling ponents.（3）In Britain, robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.（4）It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.（5）It is estimated that 20% of all ic book heroes in Japan are robots. This is an enormous number because ics are so popular that they make up a third of all material published in Japan.（6）The reliability of robots is measured in their M.T. B.F. or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today ( equivalent to working 18 hours a day for two years ) .One way robot manufacturers have increased reliability is to test every single ponent they buy, instead of the normal procedure of just testing a small sample.（7）The biggest single benefit of introducing robots claimed by Japanese panies is that they increase quality control. Once programmed, the robots can work more accurately and consistently than humans, who can get tired and bored.1.[不定向选择题]One disadvantage of using robots is that they consume____________A.too much energy B.based on American designs C.they are too costly D.they are not reliableE.quality controlF.free of chargeABCDEF确定 2.[不定向选择题]Robots are less popular in Britain today partly because____________A.too much energy B.based on American designs C.they are too costly D.they are not reliableE.quality controlF.free of chargeABCDEF确定

1.参考答案：A
参考解析：根据第四段内容可知，机器人和人做同样的工作时，消耗的能量大约比人多一百倍，所以使用机器人的一个劣势就是机器人消耗了太多的能量，所以选A。
2.参考答案：C
参考解析：根据第三段内容可知，自从1984年以来，机器人在英国的销量一直在下降，部分原因是英国的工资率太低而不能让机器人具有经济吸引力，言外之意就是机器人价格过高，所以答案为C。3.[不定向选择题]Paragraph 5____________A.Ongoing Research B.Extension of Use C.Robot Heroes D.Greater ReliabilityE.Falling DemandF.Hidden DangerABCDEF确定
