2petition(compete) in the market place now.What advertisements need to do is 3.to_attract(attract) the public’s attention.Some advertisements 4.are_made(make) up of pictures or the words of experts to show people how good the products are, 5.while others try to create advertisements people like looking at.So they spend much money 6.applying(apply) modern techniques to the advertisements.Modern

people forget that someone 9.is_trying(try) to sell them something.There are also some public advertisements 10.which aim to help increase public knowledge and make our society a better place for everyone.Ⅰ.阅读理解AEach year,hikers and mountain bikers get lost or injured in the wilderness.Search and rescue efforts can involve 20 or more people.But a new “smart” drone(无人机) can follow hiking 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。

But a team of scientists at Harvard University in the US has managed to build an entirely soft robot—one that draws inspiration from an octopus(章鱼)．Described in science journal Nature, the “Octobot〞 could pave the way for more effective autonomous robots that could be used in search，rescue and exploration. “The Octobot is a minimal system which may serve as a foundation for a new generation of completely soft, autonomous robots，〞 the study's authors wrote.Robots built for precise, repetitive movements in a controlled environment don't do so well on rough terrains(地形) or in unpredictable conditions. And they aren't especially safe around humans, because they're made out of hard and heavy parts that could be potentially dangerous to their users.So researchers have been working on building soft robots for decades. They've taken inspiration from nature, looking to animals from jellyfish to cockroaches, which are often made up of more flexible matter.But creating a completely soft robot remains a challenge. Even if engineers build a silicone(硅酮) body, it's still a grand challenge to construct flexible versions of essential parts, such as a source of power.“Although soft robotics is still in its early stage, it holds great promise for several a pplications, such as searchandrescue operations and exploration，〞Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology's Center for MicroBioRobotics, wrote in a comment. “Soft robots might also open up new approaches to improving wellness and quality of life.〞语篇导读科学家受到章鱼的启发，制造了软体机器人，本文介绍了这种机器人的研发过程、用处与局限等。

A new study has found the amount of antibiotics given to farm animals is expected to increase by twothirds over the next 15 years. Researchers are linking the growing dependence on the drugs to rising demand for meat, milk and eggs. The researchers warn the drugs could quicken the development of antibioticsresistant (耐抗生素的)infections. Such infections are already a major public health concern in the United States.Experts say when people stop living in poverty, the first thing they want to do is eat better,rather than earn more money. For most people, that means their diet should contain more meat. Increasing prosperity in Asia has meant people there are eating nearly four times as much meat, milk and dairy products as they did 50 years ago.To meet that demand, farms have put many animals into smaller spaces. As the animals are crowded together, often the easiest way to deal with some of the problems of crowding is to give them antibiotics. It’s clear that antib iotics help animals stay healthy in a crowded environment and grow faster. But bacteria can develop resistance to the drugs gradually, and the antibiotics-resistant bacteria can spread to people.Doctors find that antibiotics that once worked against the infections no longer do. The bacteria have learned ways to fight the medicine. Doctors say the heavy use of antibiotics in animals is one of several reasons for the growth of antibiotic resistance worldwide. In the United States, at least two million people get drug-resistant infections each year. At least 23,000 die from an infection.Ramanan Laxminarayan heads the Center for Disease Dynamics, Economics and Policy. He says the problem is expected to get worse. He believes the use of antibiotics in animals will soon increase sharply. He says that will not be good for human health. He and other researchers wrote a report on the study, which was published in the Proceedings of the National Academy of Sciences.

Unit 2Robots课时作业Ⅰ.阅读(2020·全国新高三开学联考)A robot created by Washington State University (WSU) scientists could help elderly people with dementia and other limitations live independently in their own homes.The Robot Activity Support System, or RAS, uses sensors (传感器) equipped in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owners to objects like their medication or a snack in the kitchen.“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected，” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.Currently, about 50 per cent adults over the age of 85 need assistance with everyday activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial pressure on the healthcare system by making it easier for older adults to live alone.RAS is the first robot researchers have tried to apply to their smart home environment. They recently published a study in the journal Cogniti v e Systems Research that shows how RAS could make life easier for older adults struggling to live independently.“While we are still in an early stage of development, our initial results with RAS have been promising，”Minor said. “Th e next step in the research will be to test RAS' performance with a group of older adults to get a better idea of what video reminders and other preferences they have regarding the robot.”篇章导读：本文是一篇说明文。

Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.The honey guide does not actually like honey, but it does like the wax in the beehives(蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the_follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.11．Why is it difficult to find a wild bees' nest?A．It's small in size.B．It's hidden in trees.C．It's covered with wax.D．It's hard to recognize.12．What do the words “the follower” in Paragraph 2 refer to?A．A bee. B．A bird.C．A honey seeker. D．A beekeeper.13．The honey guide is special in the way ________．A．it gets its foodB．it goes to churchC．it sings in the forestD．it reaches into bees' nests14．What can be the best title for the text?A．Wild Bees B．Wax and HoneyC．Beekeeping in Africa D．HoneyLover's HelperB“Fathers should be neither seen nor heard，” wrote Oscar Wilde.“This is the only proper basis for family life.” It's hard to say what Wilde would have thought of this week's cover photo or the pictures inside of dads and their children.Several clearly oppose the outdated idea of fathers as detached(使分开) from the parenting process and that's just what the photographers intended.Gregory Heisler，who did the cover photograph，says he wanted the image to show genuine affections.So，rather than use professional models，he went out and found some “real dads and their real kids”. Adds Heisler, “Instead of doing some skilful，overproduced photographs，I wanted something more authentic to the experience of being a father.” This isn't the first time that Heisler，39，has conveyed complex ideas for the cover of TIME.His photographs have decorated the front of the magazine some 20 times，ranging from Olympic athlete Jackie JoynerKersee and director Davis Lynch to former President George Bush and Ted Turner for “Man of the Year” issues in 1991 and 1992，respectively.But this week's TIME cover has special meaning，he says，because he and his wife had their first child，Lucy，16 months ago.The pictures appearing inside were all done by photographer Jeffrey Lowe.Although Lowe has not experienced fatherhood yet，he observed many warm moments of parenting by spending a lot of private time with each dad and child.Of all the pictures，Lowe was most deeply touched by the fathertobe embracing his pregnant wife.While most of the credit for the pictures rightly goes to those behind the camera，cover coordinator(协调者) Linda Freeman and assistant picture editor Mary Worrell Bousquette，who work behind the scenes，also deserve praise.Freeman，for instance，had the challenging task of making arrangements for the group portrait of child movie stars that appears on page 62. She s ays, “My greatest reward is working with these talented artists.”Bousquette edited the pictures that appear inside.“I wanted our story to show the many faces of fatherhood，”she says.At least in this issue，those fathers are seen as well as heard.15．In this week's TIME the photographers wanted ________．A．to show Oscar Wilde's view had gone out of dateB．to show honor to the famous playwright Oscar WildeC．to support Oscar Wilde's viewD．to say sorry to Oscar Wilde16．In Oscar Wilde's view，________．A．fathers should stay actively involved in their children's livesB．there should be distance between fathers and children in family lifeC．what fathers enjoy most is family lifeD．fathers aren't sure about what they should do at home17．Jeffrey Lowe managed to show fathers' feelings accurately in his photos by ________．A．trying to experience fatherhood himselfB．spending most of his time with his pregnant wifeC．studying the relationship between each member in a familyD．mixing with many fathers and their children18．Which of the following is TRUE according to this passage?A．Heisler has conveyed complex ideas for the cover of TIME several times.B．Mary Worrell Bousquette is a cover coordinator.C．Lowe was most deeply touched by his pregnant wife.D．The author praises the work by the photographers and the editors.Ⅲ.完成句子19．____________________________ could Holmes settle down and dive into his logical deduction.
