{{B}}Robotic Highway Cones{{/B}}
A University of Nebraska professor has developed robotic cones and barrels.{{U}} (1) {{/U}}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 a m, the cones could move from the side of the highway to block off the lane at that time.{{U}} (2) {{/U}}"It just seems like a very good application for robots," Farritor said. "The robotic cones would also help remove people from hazardous jobs on the highway putting barrels and cones into place," Farritor said in a report on his creation.{{U}} (3) {{/U}}This fund 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 small enough not to greatly change the appearance of the construction aides. "It would look exactly the same, "Farritor said. "Normally there's a kind of robbery, black base to them.{{U}} (4) {{/U}}"
Farritor has talked with officials from the Nebraska Department of Roads about how the robots would be most useful to what they might need.
The robots could come in handy following a slow-moving maintenance operation, like painting a stripe on a road or moving asphalt, where now the barrels have to be picked up and moved as the operation proceeds. "That way you don't have to block offa 10-mile strip for the operation," Fardtor said.
While prototypes have been made, they are not in use anywhere. Farritor said he has applied for a patent and is considering what to do next.{{U}} (5) {{/U}}He is also thinking about marketing the robots to roads departments and others across the country who may benefit from them.

D. Work on the idea began in 2002 using a National Academy of Sciences grant.
E. We replace that with a robot.

【正确答案】 A

【答案解析】[解析] 因为空格2和空格3位于同一段落中，所以它们应该在内容上围绕一个中心发展。思路：查找段落主题句。发现段首句足举例句，而段末句中出现例如篇章词This fund，因此判断前文中一定古有关资金的词语与之相呼应，发现除了空格3以外段落其他的句子中没有再谈沦到“资金”，冈此判断只有空格3处山现有关“资金”的话题，因此判断D是答案。因为该段段落的最后一句说“这笔资金允许Farrier和……一起致力于这个项目研究”，所以推测该段落在具体讲述某个项目，而该段落并没有明确的说是什么项目，发现空格后反复提到Farritor，因此推测C可能是答案，但C放在空格2处不通顺，所以C不是答案；思路：线索词对应法。A中的He在空格前句中没有呼应的名词代词，因此不是答案；而D中的We和出at也和空格前句没有呼应的词语。因此判断A是答案。
