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。

Robots are now being employed not just for dangerous tasks, such as discovering mines or rescuing people in disasters. They are also finding application as household helps 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 (人性化的) 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 participants were to sacrifice it. Situations that included vivid stories in which the robot was described as a merciful being or as a creature with its own understandings, experiences and thoughts, were more likely to stop the study participants from sacrificing it in the interests of anonymous (无名的) humans. "This result indicates that our study group attached a certain moral status to the robot," says Paulus. "One possible suggestion of this finding is that attempts to humanize robots should not go too far. Such efforts could come into conflict with their intended function—to be of help to us."(1)What has become a concern about robots?A. How to humanize them.B. How to treat them in life.C. How to use them effectively.D. How to find more applications.(2)In the study the participants probably have to decide ________.A. when to sacrifice a robotB. where to experience risksC. which robot to work withD. what robots should be like(3)What can be inferred from Paulus' words?A. Humanized robots offer less help to people.B. Humanizing robots too much may be improper.C. Certain moral status should be attached to robots.D. Conflicts often happen between humans and robots.(4)Which of the following would be the best title for the text?A. Robots, A Must for FutureB. Humanized Robots, A New TrendC.

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。

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forestsin these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken inby the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling."We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.(1)According to the new findings, taking steps to prevent northern forest fires may ________.A. result in a warming climateB. cause the forest fires to occur more frequentlyC. lead to a longer fire seasonD. protect the forests and the environment there(2)The following are all the immediate effects after a forest fire EXCEPT ________.A. large amounts of greenhouse gases enter the atmosphereB. the levels of ozone which is a type of oxygen increaseC. snow on the ground mirrors more sunlight back into spaceD. ashes from the fire fall on the ice surface and take in more radiation from the sun(3)Earlier studies about northern forest fires ________.A. analyze all aspects of how northern fires influence climateB. indicate that forest fires will pollute the atmosphereC. suggest that people should take measures to protect the environmentD. suggest that the fires will speed up climate warming(4)The underlined phrase "soak up" in the last paragraph most probably means ________.A. releasedB. absorbedC. createdD. distributed(5)From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ________.A. warm the climate as the supposition goesB. allow more snow to reflect more sunlight into space and thus cool the climateC. destroy large areas of forests and pollute the far-off sea iceD. help to gain more energy rather than release more energy【答案】(1)A(2)C(3)D(4)B(5)B【解析】【分析】本文是一篇说明文,介绍了阿拉斯加、加拿大和西伯利亚的森林大火使气候变暖,科学家们已经发现,在燃烧的树木允许更多的雪将更多的阳光反射到太空的地区可能会发生冷却。

After a morning hike in the Saneum HealingForest, 46-year-old firefighter Kang Byoung-wook has tea made from the bark of an elm tree, practices yoga (瑜伽), and makes a picture with dried flowers. He is one of 40 firefighters taking part in a three-day program, the aim of which is to offer "forest healing" (森林治愈); the firefighters all have posttraumatic stress disorder (创伤后应激障碍).Saneum is one of three official healing forests in South Korea. Soon there will be 34 more. South Koreans-many of whom suffer from work stress, digital addiction, and great academic pressure have accepted the medicalization of nature with great enthusiasm.There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it."We don't think of being outdoors as a way to increase happiness," says Nisbet. "We think other things will, like shopping or TV." But South Korea is starting to challenge this opinion.So what are some of the benefits of nature that Nisbet refers to? Being surrounded by nature has one obvious effect: It calms us and reduces our stress levels. This has been shown to lower blood pressure and heart rates.Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50-minute walk in a park had better attention and short-term memory than those who took a walk along a city street.Perhaps what's more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking.In fact, we may never know exactly what nature does to the brain. Something mysterious will always remain, and maybe that's as it should be.(1)What is Kang Byoung-wook doing?A.Getting lost in nature.B.Building up his strength.C.Trying to control a forest fire.D.Helping firefighters under stress.(2)What does Lisa Nisbet think of being outdoors?A.It is overlooked by people.B.It has nothing to do with happiness.C.South Koreans show great interest in it.D.We need more evidence for its benefits.(3)What benefit of nature did Stephen Kaplan find?A.It affects people's feelings.B.It lowers the risks of diseases.C.It helps improve mental performance.D.It does more good than physical exercise.(4)What would be the best title for the text?A.Your life in forestsB.Your brain on natureC.The future of forest healingD.The benefits of a stress-free life【答案】(1)A(2)A(3)C(4)B【解析】【分析】本文是一篇说明文,由韩国患创伤后应激障碍的消防员接受森林治愈谈起,介绍了大自然对我们身心健康的益处。

When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.Opossum (负鼠)In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.Hoatzin (磨雉)Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink birdMillipedes (千足虫)Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.Sea Hare (海兔)The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.(1)The sea hare defends itself from predators by ________.A. becoming plain in taste at the discovery of a predatorB. giving out purple ink to make itself invisible to predatorsC. releasing substance to make predators unable to smell itD. giving off smelly gas to try to drive predators away(2)Which of the following statements is TRUE according to the passage?A. The vulture carries bacteria so that predators dare not get close to it.B. The opossum fakes its death to avoid being targeted by predators.C. The hoatzin eats cow shit so that it is nick-named as "stink bird".D. The gas released by millipede was basically harmless.(3)The species that enjoys more than one defense mechanism is ________.A. vultureB. opossumC. millipedeD. sea hare【答案】(1)C(2)B(3)C【解析】【分析】本文是一篇说明文,介绍了一些野生动物是如何进行自身防御的。

(英语)高二英语阅读理解(科普环保)试题(有答案和解析)一、高中英语阅读理解科普环保类1.犇犇阅读理解A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.Shining iridescent color, which changes depending on the angle from which it's viewed, is favored by everything from birds to beetles and blossoms to butterflies."And in our research group we are of course interested in why this vivid metallic color is so widespread in nature." Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. " Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates." But iridescence also shows up in situations where reproduction is not an issue. " So what we are studying now is whether natural selection imposed by predation(捕食行为) could explain the occurrence of iridescence in prey animals."The idea that eye-catching colors could be used as a cover-up isn't a new one." The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing-Coloration in the Animal Kingdom, already in 1909, that 'brilliantly changeable or metallic colors are among the strongest factors in an animal's concealment'. And this sounds like a completely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal's concealment?""In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition." Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. "It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish." As for making use of this method for hiding in plain sight, "Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize." The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird's-eye view.(1)According to the passage, iridescence is not made use of by animals to ________. A. live a little longer by escaping their predator(捕食者) B. catch the attention of their mates C. conceal themselves when in danger D. catch sight of more colorful preys(2)From the study in the last paragraph, we can learn that ________.A. Bees can always tell the difference between a circle and an ovalB. Bees are creatures that are fascinated by sweet things that are iridescentC. If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding itD. Bees are likely to prefer circles to ovals, whether they are iridescent or not(3)What will be talked about in the following paragraph?A. Whether there are any differences between bees and birds.B. Some industries that have great interest in camouflage.C. Why birds are not effected by iridescent insects.D. Which camouflage theory applies more to birds.(4)Which of the following might serve as the best title of the passage?A. A famous camouflage strategyB. Metallic iridescent as the best disguiseC. Colors unique to animalsD. Shining colors as a sexual strategy【答案】(1)D(2)C(3)C(4)B【解析】【分析】本文是一篇说明文,介绍了彩虹色有助于生物隐藏。

(1)考查细节理解。

根据第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被动物用来通过逃离捕食者而活得更久,排除A;根据第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在这里我想指出的是,在某些物种中,尤其是那些表现出强烈两性差异的物种,比如天堂鸟、孔雀,甚至在某些蝴蝶或鱼类中,彩虹色的出现很可能是由性别选择所驱动的。
