50套高中英语阅读理解(科普环保)含解析一、高中英语阅读理解科普环保类1．犇犇阅读理解While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world's first kids to be "taught" by a digital teacher. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that appears on the student's desktop, or smartphone screen, when ordered to come.The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector's "Be sustainable with energy" — a free program for Auckland elementary schools.Just like the humans it replaced, Will is able to instantly react to the students' responses to the topic. Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students' attention, but also allows the program's developers to monitor their engagement, and make changes if needed.Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, “I have a lot of hope in this technology as a means to deliver cost-effective, rich, educational experience in the future.”The program, in place since August 2018, has been a great success thus far. Ravishankar says, " What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention." However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.（1）What was special for some elementary school students in Auckland?A. A digital teacher taught them.B. They first saw something digital.C. This was the start of a new school year.D. They could get close to smartphone screen.（2）What is the benefit of this two-way interaction?A. It can smile back.B. It can use microphone.C. It can talk any topic for free.D. It can change if necessary.（3）What's Ravishankar's attitude to Will's replacing Human educators soon?A. Optimistic.B. Doubtful.C. Unclear.D.

But for scientists, working out what is going on in an actor's head has always been something of a puzzle.Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not.Dr Steven Brown, from McMaster University in Canada, said, "It looks like when you are acting, you are suppressing (压制) yourself; almost like the character is possessing you."Brown and colleagues report how 15 actors, mainly theatre students, were trained to take on a Shakespeare role — either Romeo or Juliet — in a theatre workshop. They were then invited into the laboratory, where their brains were scanned in a series of experiments.Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love?Each actor was asked to respond to different questions, based on two different premises (前提). In one, they were asked for their own perspective, while in the other, they were asked to respond as though they were either Romeo or Juliet.The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some third-person knowledge or inferences about their character.The team said they also found additional reduction in activity in two regions of the prefrontal cortex (前额皮质) linked to the sense of self, compared with when the actors were responding as themselves.However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than "pretending" to be someone —it involves embodying (体现) the text and language.（1）How did Dr Brown's team conduct their research?A. By scanning the brain activity of some actors.B. By doing a survey with some theatre goers.C. By interviewing some theatre teachers.D. By consulting some experienced researchers.（2）What is the finding of Dr Brown's research?A. Acting is not as mysterious as people think.B. Actors' brain activity differs when they are acting.C. Acting is far more than pretending to be the character.D. Actors' brain activity is more active when they are in character.（3）How did Philip Davis react to the research?A. He supported it.B. He doubted it.C. He explained it.D. He advocated it.（4）What is the text mainly about?A. A debate of how the brain functions.B. A play written by Shakespeare.C.

A shark moving around the coastline is normally a worrying sight，but this waterborne drone (无人机) threatens floating rubbish instead of people.Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet (1.5 meters by 1.1 meter), it can carry up to 352 pounds of rubbish (159.6 kg) and has an operational battery life of 16 hours.By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat."WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines," said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches.""Our drones are designed to move through a water system, whether it's around the perimeter (周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remote-controlled model and just under $ 23, 000 for the autonomous model."Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering.（1）What do we know about the WasteShark?A. It can frighten sharks away.B. It is an ocean explorer.C. It is a rubbish collector.D. It can catch fish instead of people.（2）What does Paragraph 4 mainly tell us?A. The causes of ocean pollution.B. The dangers of using plastics.C. The severity of ocean garbage pollution.D. The importance of ocean protection.（3）What will the WasteShark do with an approaching object?A. Avoid crashing into it.B. Break it into pieces.C. Swallow it.D. Fly over it.（4）Which of the following ideas does Liparts agree with?A. The WasteShark should be used more widely.B. More measures should be taken to make water clean.C. The production cost of WasteSharks should be reduced.D. People should take a positive attitude to new technology.【答案】（1）C（2）C（3）A（4）B【解析】【分析】本文是一篇说明文，介绍一种水上无人机可以用于清理浮在水面上的垃圾。

An international team of researchers from the University of Oxford have found that the way people use the Internet is closely tied to the seasonal movements in thenatural world. Their online species searches follow the patterns of seasonal animal migrations （迁徙）.Migratory birds （候鸟） flood back to where they reproduce every spring. That migratory behavior is accompanied by some human behavior. "In English-language Wikipedia （维基百科）, the online searches for migratory species tend to increase in spring when those birds arrive in the United States," said the lead author John Mittermeier.And not just birds. Mittermeier and his team surveyed nearly 2.5 billion Wikipedia search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects, horsetails and flowering plants. Seasonal trends seemed to be widespread in Wikipedia behavior for many species of plants and animals.This finding suggests new ways to monitor changes in the world's biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for conservation.Mittermeier is encouraged by the search results. He commented, "I think there's a concern among conservationists （生态环境保护者） that people are losing touch with the natural world and that they're not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people's Wikipedia interest closely related to changes in nature."Richard Grenyer, Associate Professor from the University of Oxford, says search data is useful to conservation biologists, "By using these big data approaches, we candirect our attention towards the difficult questions in modern conservation: which species and areas are changing, and where are the people who care the most and can do the most to help."（1）What have researchers found about species searches?A.They strengthen ties among people.B.They affect the animal movements.C.They differ in language backgrounds.D.They reflect animal migration seasons.（2）What is the purpose of writing Paragraph 3?A.To summarize the research process.B.To further support the research findings.C.To show the variety of species searches.D.To present researchers' heavy work load.（3）How does Mittermeier feel about the search results?A.Satisfied with Wikipedia's service.B.Worried about Wikipedia behavior.C.Amazed at people's care about nature.D.Sad about people's not getting close to nature.（4）Why does Richard think such search data is useful?A.It helps to aim at conservation targets.B.It increases interest in big data approaches.C.It keeps track of trends in biologists' work.D.It pushes people to solve difficult problems.【答案】（1）D（2）B（3）C（4）A【解析】【分析】本文是一篇说明文，牛津大学的一个国际研究小组发现，人们使用互联网的方式与自然界的季节性运动密切相关。

高一英语阅读理解(科普环保)试题(有答案和解析)含解析一、高中英语阅读理解科普环保类1．犇犇Choose the one that fits best according to the information given in the passage you have just read.The Rapid Rise and Fall of Robot BabysittersDuring the winter of 2017, an 18-year old college student named Canon Reeves spent much of his time trailing a knee-high robot around Fayetteville, Arkansas, as it delivered Amazon packages to students. The robot, created by a start-up called Starship Technologies in 2014, is basically a cooler on wheels; it uses radars, sensors, and nine cameras to make deliveries. Reeves's job was to monitor how it handled various grounds, field comments from the public, and press the off switch if necessary. He said, "People would also ask if it could deliver beer." It couldn't.Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, had almost three times the number of positions on the recruitment committee that ended in June 2016.Over the last year, a 34-year-old businessman named David Rodriguez spent hundreds of hours following a machine called the KiwiBot around UC Berkeley's campus while it delivered Red bull and other drinks to students. To retrieve (检索) orders, the app encourages students to give the robot a wave; the robot's digital eyes will roll depending on its mood. Rodriguez, who heads business development for the start-up, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won't be out of work. Everyone holds double roles in the company. Greater robot self-governing just means employees will shift their focus to accounting, engineering, and design. Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. "A huge number of jobs will be produced as autonomous vehicles are released into the environment," Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a community college in Michigan, in autonomous-vehicle repair; Toyota has trained students in maintenance as well. "We might even see a return to low-level jobs where people come and fuel the car for you," Ramsey said. "Until we can wirelessly charge, someone needs to refuel them." The hardest-to-automate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.（1）What kind of robot is the one created by a start-up called Starship Technologies? A. A factory robot. B. A delivery robot. C. A restaurant robot. D. A construction robot.（2）What does "fall under the umbrella of" in Para. 2 mean?A. are in the category ofB. are under the protection ofC. are in relation ofD. are in the process of（3）According to Ramsey, what will happen when autonomous vehicles are put on the market?A. Autonomous vehicles will become much cheaper.B. A large number of people will be out of work.C. A lot of job opportunities will be created.D. Many people will turn to buying autonomous cars.（4）What does the last sentence in Para. 4 mean?A. Robot carers will have a competitive advantage in the future.B. Many new occupations like caring for robots come and go fast.C. We still need someone to look after robots in the future.D. Robots will create more and better jobs for people in the future.【答案】（1）B（2）A（3）C（4）A【解析】【分析】本文是一篇说明文，随着机器人被越来越多的应用，照看机器人的工作也随之发生了变化。

While every dog owner knows their dogs can read their moods perfectly, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed.The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touch-screen models were all females, this confirmed what has been observed in previous studies dogs are more efficient at reading facial expressions of people that are the same gender as their owner.（1）How did the scientists conduct the experiment?A.By leaving dogs to women who are either happy or angry.B.By mixing the selected dogs together.C.By rewarding only half of the dogs touching the screenD.By showing digital pictures of women's happy or angry faces.（2）The underlined word "trepidation" in Paragraph 5 probably means ________.A.fear and hesitationB.curiosity and eagernessC.excitement and happinessD.doubt and sadness（3）According to the last paragraph, dogs with female owners ________.A.are fond of the male facesB.are uninterested in telling the emotions on the entire facesC.have difficulty telling the moods on the faces of malesD.can only recognize emotions of females（4）What is the best title for this passage?A.Mood Changes Influence DogsB.Dogs Identify the MoodsC.dogs and Their OwnersD.Dog's Mood Research【答案】（1）D（2）A（3）C（4）B【解析】【分析】本文是一篇说明文，最新的实验发现，即狗能够识别人的面部表情的变化。

The last few years have been a painful time for the company as customers deserted its platform in 3 of newer and more 4 devices. This may be the company’s last chance to 5 a vital player in an increasingly crowded marketplace.Two brand new devices are perhaps a fresh 6 for a company that has seen its global market share 7 from 20 percent three years ago to just over 3 percent today.For BlackBerry CEO Thorsten Heins, it’s another chance to remake a faded8 . “We have 9 been on a journey of transformation, not only a journey to transform our business and our brand, 10 one that I truly 11 transforms mobile communications into true mobile computing,” he said.The company promises the same 12 level of network security the BlackBerry is known for, 13a fast new browser and a more intuitive operating system. The Z10 14 much like the touch-screen phones popularized by its competitors, but the Q10 maintains the “qwerty” keyboard that has becom e BlackBerry’s trademark.Besides the technical and cosmetic (外观上的) updates, Heins says the company will no longer be called RIM or Research In Motion.“Our customers use a BlackBerry, our 15 work for BlackBerry and our shareholders are owners of BlackBerry. From today on, we are BlackBerry 16 in the world,” he said.Shareholders will be watching if customers 17 the new devices. The company’s stock has dropped as much as 90 percent in the last four years as it lost 18 to competitors.
