共用题干Wide World of Robots
Engineers who build and program robots have fascinating jobs. These researchers tinker(修补)with ma-
chines in the lab and write computer software to control these devices."They're the best toys out there,"
says Howie Choset at Carnegie Mellon University in Pittsburgh.Choset is a roboticist,a person who designs,
builds or programs robots.
When Choset was a kid,he was interested in anything that moved一cars,trains,animals.He put motors
on Tinkertoy cars to make them move.Later,in high school,he built mobile robots similar to small cars,
Hoping to continue working on robots,he studied computer science in college.But when he got to
graduate school at the California Institute of Technology in Pasadena,Choset’。labmates were working on
something even cooler than remotely controlled cars:robotic snakes.Some robots can move only forward,
hackward, left and right. But snakes can twist(扭曲)in many directions and travel over a lot of different
types of terrain(地形)."Snakes are far more interesting than the cars,"Choset concluded.
After he started working at Carnegie Mellon,Choset and his colleagues there began developing their own
snake robots.Choset's team programmed robots to perform the same movements as real snakes,such as
sliding and inching forward.The robot、also moved in ways that snakes usually don't,such as rolling.
Choset’s snake robots could crawl(爬行)through the grass,swini in a pond and even climb a flagpole.
But Choset wondered if his snakes might be useful for medicine as well.For some heart surgeries,the
doctor has to open a patient's chest,cutting through the breastbone.Recovering from these surgeries can be
very painful.What if the doctor could perform the operation by instead making a small hole in the body and
sending in a thin robotic snake?
Choset teamed up with Marco Zenati,a heart surgeon now at Harvard Medical School,to investigate the
idea.Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.
A company caikd Medrobotics in Boston is now adapting the technology for g urgerie9 on people-
Even after 15 years of working with his team’s creations,"I still don't get bored of watching the motion
of my robots,"Clioset says.Zenati tested the robot on people after usinlg it in pigs.A:RightB:WrongC:Not mentioned
选项
Zenati tested the robot on people after usinlg it in pigs.
A:Right
B:Wrong
C:Not mentioned
答案
B
解析
根据第二段尤其是第二段最后一句话“Later, in high school, he built mobile robots simi- lar to small ears.”可知题干表述正确。
根据第三段倒数第二、倒数第三句话“Some robots can move only forward, backward, left and right.But snakes can twist in many directions and travel over a lot of different types of terrain." 以及第四段第二、三句话“Choset' s team programmed robots to perform the same movements as real snakes,such as sliding and inching forward.The robots also moved in ways that snakes usually don't, such as rolling.”可知题干表述错误。
根据第四段第一句话“After he started working at Carnegie Mellon, Choset and his col-leagues there began developing their own snake robots.”和该段最后一句中的“Choset' s snake”可 推知题干表述正确。
文中没有提到Choset的机器蛇比别人做的能做更多的动作,只是说他的机器蛇比真蛇 能做的动作还多。故选C。
提到将机器蛇运用于心脏病治疗的价值的是文章的第五段,但文中只是说这可以减少 心脏病人做胸腔切开手术的痛苦,并没提到这可以节约时间。故选C。
倒数第三段提到Zenati将机器蛇应用于塑料胸腔模型,他和Choset在猪的身上作了测 试。倒数第二段说Medrobotics公司将这项技术应用到了心脏病人身上。题干表述与文章不 一致,因为Zenati并没在人身上测试该技术。故选B
提到Medrobotic、公司的只有倒数第二段,但该段只是说这个公司将机器蛇技术应用到 了外科手术上,并没提到该公司因此获得了很大的收益。故选C。第3部分:概括大意与完成句子
