Howie Choset，a roboticist，has been researching and building robots，particularly snake robots，at Pittsburgh’s Carnegie Mellon University for years.
Choset believes that his snake robot and others like it help reduce medical costs by making complex surgeries (外科手术) faster and easier.Choset says his new design is smaller and more flexible than earlier models.The size of surgical robots allows surgeons to operate with far less damage to the body，helping the patient heal faster.For example，instead of opening the entire chest up during heart surgery，a small hole is made，and a thin robotic snake crawls inside to the proper spot.
Dr Ashutosh Tewari of Cornell University Medical Center has used robotic tools to perform thousands of operations.Tewari said he’s most excited about the potential for surgical robots to do things humans can’t do.He said the variety of sensors available for surgical robots keeps expanding，even as
they get smaller.He said they may one day be able to test chemicals or blood in the body，or even the electrical connections in nerves.
Choset has also built larger snake robots designed for search and rescue，or just exploration.They can climb poles or trees and then look around through a camera in the head，and slid through places humans can’t reach.
Another expert at Carnegie Mellon stresses that there’s still an enormous gap between humans and even the most high-tech robots.Manuela Velosa noted that robots have been built that are good at one or two tasks—but not at the variety of tasks humans perform without even thinking.
Velosa has been building robots that ask humans for help when they don’t know what to do，as well as teams of robots that play soccer against each other.Sometimes，the robots surprise her by having once defeated the other team.
“It was programmed by me，but it looked to me as if they learned，” she said.“I believe we are much closer to having robots be able to exist with humans peacefully.The beautiful thing is you see the robots learning.”
6．How does Choset help save medical costs? A．By changing the size of robots frequently. B．By designing larger snake robots.
C．By making complex surgeries faster and easier. D．By improving the models of earlier snake robots.
7．The main advantage of using the thin surgical robot is________. A．reducing the damage to the body B．proving the technology useful to them C．helping the doctors make much money D．worsening the patient’s sickness 8．According to Manuela Velosa，________. A．robots will replace humans in the future
B．robots can do much better than humans at some tasks C．no robots can be made to turn to humans for help D．robots are able to learn by themselves 9．What can be inferred from the text?
A．The snake robot is thought to have no potential. B．Larger snake robots are not practical. C．Doctors will refuse to use the snake robot. D．The future robot will be smarter and more popular. 10．What is the text mainly about? A．Three famous roboticists. B．Researching and building robots. C．How to make snake robots. D．Different ideas on robots.
课时作业(三十二) Ⅰ.单项填空
1．解析： 考查交际用语。All right好吧；All the same仍旧，完全一样；No problem没问题；Take care保重。由语境可知，两人在道别，所以回答时应用“Take care(保重)”，D项正确。
答案： D
2．解析： 考查时态和语态。句意为：——工作计划的改变宣布了吗？——哦，天哪！我完全忘了那件事。我现在就做。问话人想知道的是事情的结果，因此用现在完成时，又因announce与the change of the schedule之间是逻辑上的动宾关系，应用被动语态。
答案： A
3．解析： 考查强调句。句意为：就是这些有毒的产品可以引起流感症状，例如头疼和肌肉酸疼。分析题干可知，本题考查“It is＋被强调部分＋that/who从句”强调句型，被强调部分为主语these poisonous products，故选B项。
答案： B
4．解析： 考查倒装句。句意为：在巢湖边有一座繁荣的城市——合肥，它是安徽省的政治、经济、文化中心。介词或介词短语置于句首时，句子要全部倒装，即：谓语放于主语之前。且此处表示一个客观的事实，故用一般现在时。
答案： A
5．解析： 考查非谓语动词。句意为：这位巨星在他的经纪人的陪同下，出现在法庭上。The superstar与accompany构成逻辑上的动宾关系，故此处用动词的-ed形式表伴随。
答案： D
6．解析： 考查连词辨析。句意为：我还没有来得及感谢那个旅游者，他就已经消失在雨中了。before在……以前；when当……时候；until直到；while尽管。根据语境可知，答案A正确。
答案： A
7．解析： 考查定语从句。句意为：在生活中我们可以看到许多这样的例子——积极的想法能够完全改变一个人。where相当于in which，引导定语从句，在从句中作地点状语，修饰先行词many examples。
答案： C
8．解析： 考查主语从句。句意为：犯错误是在所难免的。重要的是你事后如何去应付。空处引导主语从句，且在从句中作主语，应用连接词what。
答案： B
9．解析： 考查虚拟语气。insist在此表示“坚持，坚决主张”，后面that引导的宾语从句用虚拟语气。即insist that...(should) do sth.，故选A。
答案： A
