问题 共用题干Robotic Highway Cones
A University of Nebraska professor has developed robotic cones and barrels.These robotic cones and barrels can move out of the way,or into______(51),from computer commands made miles away. They can even be programmed to move on their own at any particular part of the day,said Shane Farritor,an assistant professor of mechanical engineering at Nebraska.
For example,if workers arrived at 6 am,the cones could move from the side of the highway to______(52)off the lane at that time.And they can return to the______(53)place at the end of the day."It just seems like a very good application for robots."Farritor said."The robot-ic cones would also help______(54)people from hazardous jobs on the highway putting barrels and cones into place,"Farritor said in a report on his creation.
Work on the idea began in 2002 using a National Academy of Sciences grant. The______ (55)allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard.
The robots are placed at the bottom of the cones and barrels and are______(56)enough not to greatly change the appearance of the construction aides."It would look exactly the same,"  Farritor said."______(57)there's a kind of rubbery,black base to them. We replace that ______(58)a robot."
Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most______(59)to what they might need.
The robots could come in handy following a slow-moving maintenance operation,like paint-ing a stripe on a road or moving asphalt,______(60)now the barrels have to be picked up and moved as the operation______(61)."That way you don't have to block off a 10-mile strip for the operation,"Farritor said.
______(62)prototypes have been made,they are not in use anywhere. Farritor said he has______(63)for a patent and is considering what to do next. He is thinking about starting a small business. He is also thinking about______(64)the robots to roads departments and others across the country who may______(65)from them.
选项 51._________A: workB: placeC: orderD: action
答案B
解析根据前后文可知，该处内容是与其前out of the way相对着的，因此选项中place恰当，该句句意是，几英里以外的电脑就可以发出指令将这些机器人锥形路标和路障移开或者移入某一地点。故本题选B。 由于工人们要在高速公路上施工，因此这些锥形障碍要移动到行车道上设置障碍，以方便工人们施工。在行车道上设置障碍即block off the lane。故本题选A。 在一天的最后，也就是工人们施工结束的时候，这些锥形障碍当然是返回原来的位置（original place)。故本题选D。 该句句意是，机器人还可以使人们从在高速公路上放置路标和路障的危险工作中解脱出来。“从……中解脱出来”是remove...from...。故本题选C。 前一句说，这个想法使用的是国家科学研究院提供的资金。而The______ (55) 明显是前一句所提到的的grant，即“资金”。故本题选D。 由于机器人安装在锥形路标和路障的底部，足以不改变这些路标路障的原貌，可见这些机器人足够的小，即small。故本题选C。 普通的路标、路障带有一个黑色的橡胶底座。因此该处用Normally，选B。 结合上下文可知，此处that指的是前句所提到的“黑色的橡胶底座”，该句是说“用机器人换掉橡胶底座”。replace... with...意为“用……替换……”。故本题选D。 该句是说怎样才能使机器人最有利于他们的需要。be useful to意为“对……有用，有利于”，故本题选C。 该句说，机器人可以用于缓慢移动的维护性的操作，例如在为公路粉刷白色的标线操作中需要随时摆放和移动路标、路障的地方。该句是一个地点状语从句，由where来引导。 由上题解析可知，这里是“在工作进行中”，因此用proceeds。故本题选A。 逗号前面说，路障的雏形已经做成，而后面则说还没有投入使用。显然该处需要一个转折连接词while。故本题选B。 “申请专利”是apply for a patent。故本题选A。 上一句说，他计划开一家小型公司。显然是要推梢( marketing）这种路标、路障。 该句是说，他打算向公路部门和其他国内能受益于这项发明的地方推销。 benefitfrom意为“从……获益”。故本题选A。
