trails(小路) without a pilot’s assistance.This could allow rescuers to search more efficiently.Scientists outfitted a craft with a single camera.As the drone’s “eye”,the camera pointed forwards.But having an eye wasn’t enough.The drone also needed a “brain” to unders tand what it was seeing.And that brain would have to recognize what constitutes a trail.Camera images,however,can be very difficult for a computer to interpret,study leader Alessandro Giusti notes.So he and his team used photos of forest trails to train th eir drone’s neural network(神经网络).They attached three GoPro cameras to a single headband.One camera pointed straight forward.The other two were directed 30 degrees to the right and left of the centre.A hiker put the package on and then hit the trails in a forested part of Switzerland.Over several weeks,the cameras recorded a total of 8 hours of video covering 7 kilometres of trails.The researchers then divided the video into individual still images to train the neural network.The network learned to identify what a trail looked like.The team then tested the program with unused images from the video.The computer did a slightly better job than the people had in correctly classifying the images.This meant the drone was ready to navigate the real world on its own.Giusti and his team took their now “smart” device to a forest with trails that had not been used in the drone’s training.It flew along the path,constantly adjusting its direction based on the images coming in through its camera.The drone didn’t perform as well in real-life as it did in the lab,Giusti admits.That’s because the drone’s camera took lower-quality images than the cameras that had been used to train it.As a result,the images being taken by thedrone looked different,he explains.This confused its neural network.“It’s an exciting use for neural networks,” says Christopher Rasmussen,a computer-vision scientist who was not involved with the study.“However,the problems faced in the experiments show that there are still some important issues to be w orked out.”1.The “smart” drone has been created in order to help .A.find travelers who get lostB.ensure the safety of travelersC.deliver necessities to travelersD.show travelers the way to a place2.While being tested to classify the images in the lab,the computer .A.did as well as the peopleB.did a lot better than the peopleC.did much worse than the peopleD.did a little better than the people3.Why didn’t the drone perform well in the forest?A.The light in the forest was very poor.B.The trees or bushes covered the trails.C.The drone couldn’t fly very low there.D.The pictures taken were of poor quality.4.What is Christopher Rasmussen’s attitude towards the results of the experiments?A.Critical.B.Doubtful.C.Objective.D.Optimistic.B(2021·石家庄调研检测)Shopping centres,stadiums and universities may soon have a new tool to help fight crime.A California company called Knightscope says its robots can predict and prevent crime.Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope.He says,“These robot security guards will change the world.Our planet has seven billion people on it.It’s going to qui ckly get to nine billion people.The security equipment that we have globally is just not going to develop that fast.The company’s Autonomous Data Machines can become the eyes and ears of law enforcement (执行).”“You want it to be machines plus humans.Let th e machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work,so it’s always working all together.”The machines are one and a half meters tall and weigh 136 kilograms.They do not carry weapons but they have day-and-night time video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may become concerned about their privacy,especially in connection with the video recordings.Some people may worry that such recordingswill appear on the Internet.Eugene Volokh,a law professor at the University of California,says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in the US.Workers in the company are working overtime to meet the demands of the market.At least 25 other countries are also interested in these robotic security guards.5.What can this new tool do for humans?A.Make strategic decisions.B.Keep watching day and night.C.Carry heavy weapons.D.Stop crime autonomously.6.Why are people worried?A.Their privacy may be let out.B.The robots are very expensive.C.Robots will replace humans.D.They will be out of work soon.7.Which of the following can be the best title of the text?A.Robots Are Becoming More PopularB.Robots Contribute a Lot to

Unit 2 RobotsⅠ.阅读理解A(2018·南昌十校二模)I hate Black Friday sales. It's often a gathering of people who are there for many different reasons. Some are looking for a deal on that one item for their loved one, or perhaps themselves. Their intentions are completely unrelated to the festive time of the year.It was several years ago when my wife asked me to meet her at the local department store on Black Friday morning. They had advertised a child's bike that she wanted to purchase for our son. We stood with a very large crowd, waiting for the manager to blow the whistle. After a while the whistle blew. It was like throwing a bucket of small fish into a tank of sharks. I told my wife that if we obtained a bike, fine, but if we did not, I was OK with that too.As the pile of bikes began to gradually decrease in size, I saw my polite opportunity to wrap my hands around the corner of one of the boxes. I lifted it up and suddenly felt some mild resistance. I looked up to see one of the largest gentlemen I had ever seen in my life. Frightening was not the word to describe his presence. He wore lots of belts of metal studded leather around both arms and even his neck. Tattoos (文身) were an obvious passion of his.I started to give up the box but he gently pushed it back in my direction and back into my hands. He then directed it into my shopping cart. He looked at me, smiled, and said, “Merry Christmas.” My wife and I went to the checkout, paid for the bike and went home. All the way home I was thinking that this moment was by far the best gift I had ever received for Christmas. The kindness of a stranger broke all preconceived notions(预想) I may have had of stereotypes and prejudices.【文章大意】本文是一篇记叙文。

课时作业 32Ⅰ.阅读理解(2019·陕西省榆林市第一中学高三检测)Robots come in many shapes and sizes, but scientists in Zurich, Switzerland, have developed one new robot called Pleurobot, which looks and acts just like a salamander (火蜥蜴)．To create the robot, scientists took hun dreds of X­rays of real salamanders. They studied the images of these animals to see which joints (关节) and muscles the animals use as they move. Then the scientists built the Pleurobot's skeleton to move just like the real thing. This makes the robot's movements incredibly lifelike.According to experts, salamanders were among the first animals to develop a skeleton and nervous system that allowed them to travel on land. “By studying the modern salamander, we have a time window to the ancestors of all vertebrates(脊椎动物), including humans，” Auke Ijspeert, the designer of the robot, told scholastic News Online.Both people and salamanders have a spinal cord (脊髓). An injury to the spinal cord can result in the inability to move. Now, there is no cure for paralysis (瘫痪). Ijspeert hopes that the Pleurobot can help change that. Because these studies could help researchers develop new ways to help people who have been paralyzed by spinal cord injuries.Scientists think that the Pleurobot could also be used for search­and­rescue tasks too dangerous for humans. Because the robot is low to the ground and has a wide range of motion, it could be used to get into dangerous places, like fallen buildings, to look for survivors. Thanks to its waterproof suit, the robotic salamander could even participate in underwater missions.Experts are now working on a smaller, sturdier (harder to break) model of the Pleurobot. They expect this one to be even better suited for getting into small spaces to do dangerous work.这篇文章主要讲了瑞士的科学家发明了一款新的机器人，这款机器人看起来有些像火蜥蜴。

2021⾼考英语⼀轮复习Unit2Robots课时作业新⼈教版选修7（含解析）Unit 2 RobotsⅠ.阅读理解A[2020·昆明市⾼三复习诊断]Artificial intelligence(AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like liver cancer in ways that were never before possible.Rishi Rawat, who teaches AI at the University of Southern California in Los Angeles, is part of a team of scientists researching how AI and machine learning can more easily recognize cancerous growths in the liver. Rawat provides information about cancer cells to a computer. He say s, “You can put the data into them and they will learn the patterns and the pattern recognition that's important for making decisions.”David Agus is another researcher. He believes that machines are not going to take the place of doctors. “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can't recognize by itself.”Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Nowadays, researchers take a thin piece of tissue (组织), put it on a small piece of glass and add color to see the cells better. That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns or structures, and learn how the cells are organized.The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes. Agus says the process could be done for almost no cost in the developing world and that having a large amount of information about patients is important for a machine to effectively do its job in medicine.The researchers of the university are now only studying liver cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.1．What can AI do with the help of the information provided by the researchers?A．Recognize cancer patterns.B．Treat liver cancer.C．Collect useful information.D．Store cancerous cells.2．What can we learn about AI?A．It will be able to replace doctors.B．Patients are unlikely to be cancerous again with its help.C．It is making a difference in taking care of patients.D．It can recognize cancer more accurately.3．What's the author's attitude towards the future of AI?A．Optimistic. B．Doubtful.C．Curious. D．Cold.4．What is the best title for the text?A．AI Is Used to Treat CancersB．AI May Compete with DoctorsC．AI May Make Doctors BetterD．AI Is Better at Curing CancersB[2020·南昌模拟]Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding applications as household help and as nursing assistants. As increasing numbers of machines, equipped with the latest artificial intelligence, take on a growing variety of specialized and everyday tasks, the question of how people see them and behave towards them becomes ever more urgent.A team led by Sari Nijssen of Radboud University and Markus Paulus, Professor of Developmental Psychology at Ludwig-Maximilians-Universitaet(LMU), have carried out a study to determine the degree to which people show concern for robots and behave towards them based on moral principles.According to Sari Nijssen, the study set out to answer the following question: “Under what circumstances would adults be willing to sacrifice robots to save human lives？” The participants were faced with a hypothetical (假设的) moral dilemma: Would they be prepared to put a single person at risk in order to save a group of injured persons? In the situations presented the intended victim was either a human, a humanoid robot that had been humanized to various degrees or a robot that was clearly recognizable as a machine.The study suggested that the more the robot was humanized, the less likely。
