Unit 2 Cloning一、阅读理解。Kanda really doesnt like to walk alone.The scientist from a research institute of intelligent robots finds the experience so boring that hed rather driveeven though he lives close to his lab and knows that walking is healthy.“I enjoy walking with someone，like with my wife，with my daughter，” Kanda said.“But they are not always available.”So Kanda，who specializes in humanlike bots，developed a robotic walking partner that could make small talk based on its surroundings，which，he hopes，might motivate people to get out and exercise more.The bot rests on a persons shoulder like a boxy parrot.It weighs about a pound and a half and sits roughly 8.5 inches high，and is 3.5 inches wide and 10 inches long.A microphone，a speaker，and an internal camera allow it to municate.Its even equipped with a smile.Kanda and his team collected video from five different locations，including a garden and a shopping mall，and created a dataset of small talk topics related to each location.Then they programmed the robot to associate visual cues with specific topics.A special speech software provided the robot with a voice.Near a group of parked cars，for example，it might say，“In a big parking lot， sometimes I forget where I parked.”They tested the robot on 15 volunteers，10 males and 5 females，who were paid and averaged about 26 years old.“Have you ever blown a puff of dandelion（蒲公英） seeds into the air？”The robot asked a participant，who smiled and responded，“Yes，I often did that when I was a child.” Although several participants noted the robots weight，Kanda was surprised that no one considered the experience strange or funny.“I guess people enjoy new technologies，” he said.Just like a human partner，Kandas bot isnt perfect.Its not able to go for walks in heavy rain and，while the robot can make expressions，it cant really hold a conversation，about which Kanda is most worried.Despite its limits，Kanda was forted by the bots presence.“I felt a kind of sense of being with someone，” he said，“particularly when it spoke.”【解题导语】本文主要介绍了新研发的陪人散步的机器人。1.Why does Kanda have the idea of developing a robotic walking partner？A.Because he wants someone to acpany him while walking.B.Because he has never developed a robot like a parrot.C.Because his family are unwilling to walk with him.D.Because he is crazy about developing robots.A解析：细节理解题。根据第一段的“I enjoy walking with someone，like with my wife，with my daughter，Kanda said.But they are not always available.”可知，Kanda发明陪人散步的机器人的原因是想找个人在他散步时陪他，故选A。2.What characteristic does the robot have？A.It can “speak” and “see”.B.It can walk like a human being.C.It can municate with people freely.D.It is much more humorous than a real person.A解析：推理判断题。根据第二段倒数第二句以及第三段的“Then they programmed.with a voice.”可推知，这种机器人可以说话还可以看，故选A。3.What is necessary for the robot to function？A.A small size.BA boxy shape.C.A human partner. DA speech software.D解析：细节理解题。根据第二段倒数第二句和第三段的“Then they programmed.A special speech software provided the robot with a voice.”可知，这种机器人是要配备麦克风、扬声器、内置摄像头以及特殊的语音软件的，故选D。4.What is Kanda most likely to do about his robot next？A.To make it more convenient to carry.B.To improve its conversational skills.C.To enable it to walk in heavy rain.D.To better its sound system.B解析：推理判断题。根据最后一段第二句的“it cant really
