A University of Nebraska professor has developed robotic cones and barrels. (46) . 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 block off the lane at that time. (47) . "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.
(48) . The fund allowed Farritor to work on the project with graduate students at Nebraska and his assistant Steve Goddard.

[填空题]After Australia changed its procedures for recruiting overseas students, more and more foreign students are coming to study in Australia.

[单项选择]The procedures followed by scholars studying literature are often unsatisfactory: the control over a cognitive project as a whole is often lost. The literary scholar seems to be collecting data, which is a preliminary operation, without making use of them. Like a diligent ant gathering food it will never eat, the contemporary literary scholar seems intent upon writing footnotes of a book s/he will never try to read.
I propose that at the outset of a research project it is necessary to render explicitly the questions the scholar will try to answer, what methods will be used and the reason why s/he thinks that it may be worthwhile answering such questions. More over, the work of the people concerned with the study of literature seems casual. For instance, much research is devoted to one author, often on the occasion of an anniversary. Now there is no reason to think that our observations will be more valid, urgent, appropriate, useful, or interesting if the author of the texts we ar
A. previous authors written about by others.
B. earlier scholars who wrote comparative literary works.
C. earlier methods for research.
D. repeats of researc
