Wide World of Robots
Engineers who build and program robots have fascinating jobs. These researchers tinker (修补) with machines in the lab and write computer software to control these devices. "They're the best toys out there," says Howle 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--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 Califomia Institute of Technology in Pasadena, Choset's labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, 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 bagan 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 robots also moved in ways that snakes usually don't, such as rolling.
Choset's snake robots could crawl (爬行) through the grass, swim 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 called Medrobotics in Boston is now adapting the technology to surgeries 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," Choset says.
1. Choset began to build robots in high school.回答TF正确获得10.00分中的10.00分
2. Snake robots could move in only four directions.回答TF正确获得10.00分中的10.00分
3. Choset didn't begin developing his own snake robots until he started working at Carnegie Mellon.回答TF正确获得10.00分中的10.00分
4. Zenati tested the robot on people after using it in pigs.回答TF正确获得10.00分中的10.00分
5. The robotic technology for surgeries on people has brought a handsome profit to Medrobotics.回答TF正确获得10.00分中的10.00分反馈解析:
1. 利用题干关键词high school和build robots可以定位到第二段最后一句,即“后来,在高中时,他开始制造与汽车机器人相似的移动机器人”,可知题干信息与原文信息一致,故选T。
2. 利用题干关键词move和direction可以定位到第三段第二句到第四句,可知Choset的实验室的同事们正在研究比遥控车更酷的东西,即机器蛇。一些机器人只能向前、向后、向左或向右移动,但是机器蛇可以向多个方向扭曲。因此题干信息与原文信息不一致,所以选F。
3. 利用题干关键词robot snake和work at Camegie Mellon可以定位到第四段第一句,即“他在Carnegie Mellon工作后,Choset和同事们开始设计自己的机器蛇”。题干信息与原文信息一致,故选T。
4. 利用题干关键词pig可以定位到第六段第二句。可知Zenati先在塑料模型上实验,然后又在猪身上实验。题干信息与原文信息不一致,因此答案为F。
5. 利用题干关键词profit和Medrobotics可以定位到第七段,可知Medrobotics正在采用这项技术,但并没有提及获得巨大利益,因此答案为F。理工英语4 某公司发行总面额1000万元,票面利率为12%,偿还期限5年的债券,发行费率3%,公司适用所得税率25%,该债券发行价为1200万元,则债券资金成本为( )A.0.0829B.0.103C.0.0927D.0.0775公司财务 中国公民到国外旅游的支出应计入国际收支平衡表中的资本项目。
