问题     Scientists in the 1950s proclaimed the robot the brainwave (灵感，灵机) of the future—it would free housewives of drudgery (单调沉闷的工作) and fill factories with tireless work force. But in many ways, the brainwave has been a washout.
    Robots can paint cars, salvage (收集) nuclear fuel and even assist in brain surgery, but they’re still pretty dumb.
    Mr. Reddy says robots are dumb "because we haven’t taken the trouble to put the pieces together, not because we don’t know how. That takes money and time and effort, and we don’t have the money".
    But today robots can recognize forms and shapes and measure distances. They can hear and speak by using computers that recognize thousands of words. Their sensors can detect smoke or fumes. They can move about rolling on wheels or walk with as many as eight legs like a spider on uneven terrain (地面,地带). In addition, they can recognize texture and the force of a movement, such as pressing.
    Many robots have one or two of these abilities to some degree, but creating a competent robot that combines most or all of them has been difficult. Scientists have also found it difficult to match human abilities that most people take for granted such as the finger’s dexterity (灵巧,熟练) or the ability to identify objects.
    "The list of things that robots can do better than humans is much shorter than the list of things robots cannot," says Tom Smith from the Cambridge Mellon Institute.
The present state of robots is due to______.
选项 A、scientists’ inability to create a competent robot
B、shortage of money and time
C、inadequate technical know-how
D、the trouble in putting together a robot
答案B
解析 本题是一道具体细节题。问目前机器人的开发利用情况不理想是由于什么原因。利用查阅式阅读法，我们可以在文章第三段中找到相关内容。这段指出，莱笛先生说机器人之所以很笨拙，“是因为我们还没有在组件上下大工夫，而并非我们不懂得其中的奥妙。而要进一步开发得需要资金、时间和精力，我们缺乏资金”。因此，本题的正确答案应是B“由于缺乏资金和时间”。
