9.Contestants from around the world met in Pomona,California,this month to test their skills at things like driving a car,walking down stairs,and opening doors.Sounds easy,right?But the competitors weren't people-they were robots!The bots were participating in(参加) the final round of the US's DARPA(Defense Advanced Research Projects Agency) Robotics Challenge.This event,which took place on June 5-6,tested robots on how well they could respond during a disaster and the winning team finally took home a $2million grand prize.
The DARPA challenge was created after the 2011Fukushima nuclear disaster in Japan.An earthquake caused a tsunami,which damaged a nuclear power plant.Workers at the plant needed to shut off an important valve(阀门),but it was too dangerous for humans to reach it.The US scientists at DARPA wondered whether the disaster could have been avoided if a robot had been sent to do the job.So they set up the robotics competition.
Turning a valve was just one task a robot might have to perform when entering a disaster zone.In addition to doing this,robots participating in the challenge had to navigate a course containing several other tasks:driving and exiting a vehicle,opening a door,walking over or clearing objects,cutting a hole in a wall,plus climbing a flight of stairs.
Teams had to complete the challenge in one hour,and points were awarded based on how quickly the robots completed a task.They didn't have to attempt all the tasks.To make things even more realistic,challenge organizers caused short computer-system blackouts(断电) that prevented robots and the human operators controlling them from communicating.That means teams had to program their robots to be partially autonomous(独立的).Robots also couldn't be attached to anything that could keep them from falling down,which happened a lot.
29.What do we know about this year's DARPA challenge?C
A.It lasted five days.
B.It was held in Japan.
C.Its winner got a cash prize.
D.Its winner will work in Fukushima.
30.What does the underlined part"the job"in Paragraph 3refer to?B
A.To open a door.

解答 29-32 CBCC
29.C.细节理解题.由第二段This event,which took place on June 5-6,tested robots on how well they could respond during a disaster and the winning team finally took home a $2million grand prize.可知,加利福尼亚州举行的为期两天的DARPA机器人挑战赛冠军得主获得了200万美元的现金大奖.故选C.
30 B 篇章结构题.划线部分所在句的 the disaster 指代上文的福岛核电站事故,科学家认为如果当时能有机器人去关闭核电站的阀门,那么那场事故就会避免,故此处的the job指关闭阀门.故选B.
31.C.细节理解题.由最后一段Teams had to complete the challenge in one hour,and points were awarded based on how quickly the robots completed a task.介绍机器人参赛规则可知,参赛机器人需要在一个小时之内完成比赛内容.故选C.
32 C 主旨大意题.本文主要介绍了在加利福尼亚州举行的DARPA机器人挑战赛赛况及其规则.故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
