This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the "groundbreaking" discovery is "realistically the only way" that anti-HIV combination treatments can be produced at a cost low enough for the developing world.They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves.

2．犇犇Choose the one that fits best according to the information given in the passage you have just read.Being able to land safely is a critically important skill for all flying animals. Comparatively speaking, ground living animals face no particular challenge when they need to stop running or crawling, while flying animals move at much higher speed, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.In the past it was believed that, in terms of flying mechanics, there was little differencebetween bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢体). This makes coordinating (协调) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or completely reverse it, something a bird cannot easily do.Another interesting characteristic of bat flight is the way in which bats land-upside down! Unlike birds which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. One downside to this landing routine is that the bats often land with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force; these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.（1）Which of the following is the topic of the passage?A. Places where flying animals choose to land.B. Why scientists have difficulty observing bats.C. Differences in the eating habits of bats and birds.D. Ways in which bats move differently from birds.（2）Which of the following is a false assumption about bats that was recently corrected?A. They cannot hear any sound.B. They sleep upside down.C. They fly similarly to birds.D. They hide in tree branches.（3）The word "it" (in 2nd paragraph) probably refers to "______".A. the distance to the netsB. the sense of flying heightC. the flying directionD. the ability to change the speed（4）According to the passage, which of the following is NOT true?A. Bats might hurt themselves when landing.B. Bats can hang upside down like birds.C. Bats can adjust speed before landing.D. Bats and birds land in different ways.【答案】（1）D（2）C（3）C（4）B【解析】【分析】本文是一篇议论文，作者用研究事实来证明蝙蝠在飞行及运动方式与鸟类完全不同。

One spring day, once the flowers have begun to open, a bee will hover (盘旋) and zip through your yard and dive-bomb your picnic table. While you're thinking about avoiding an attack, that bee is focused on something else entirely: me.A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, straw-like tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her co-workers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the comb. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only one-twelfth of a tea spoon of me.The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad.Alas, my good health is not guaranteed. The problem lies in the growth of industrial agriculture and the use of pest control chemicals, as well as changes in weather patterns, all of which reduce the number of flowers bees have to visit I'd appreciate your letting your own garden grow just a little wild My future depends on all of us fostering spring and summers wild flowers, thus helping the bees, who give so much—to you, to me—without ever asking for anything in return.（1）What does "me" refer to in the passage?A. The flowerB. The beeC. WaterD. Honey（2）What is the 2nd paragraph mainly about?A. Bees' special talentB. Bees' hard work.C. Bees' living environment.D. Bees' social behavior.（3）What is the purpose of the passage?A. To appeal for help for honeybees.B. To talk about the history of a treasure.C. To put forward techniques for gardeners.D. To argue against the control of chemicals.【答案】（1）D（2）B（3）A【解析】【分析】本文是一篇说明文，用拟人的手法，以蜂蜜的口吻，介绍了蜜蜂虽然只有六周左右的寿命，但用其一生辛勤为人类酿造蜂蜜，人类应该保护蜜蜂。

【英语】高三英语阅读理解(科普环保)专项训练100(附答案)含解析一、高中英语阅读理解科普环保类1．犇犇阅读理解News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world's first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That's why many news anchors were worried: Will AI replace us in the near future?To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person's voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programsBoth the technologies used to make Xin's performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don't always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.（1）What does the underlined word "reluctant "in the first paragraph mean?A. Delighted.B. Unwilling.C. Confused.D. Optimistic.（2）What can we infer about previous news robots?A. They read news without expressions.B. They looked like a human beingC. They could interview sports starsD. They could interact with audience.（3）What do we know about the third technology?A. This technology is very perfect so farB. This technology is quite popular nowC. This technology remains at the theoretical stageD. This technology is far from mature.（4）From the last paragraph, we can draw a conclusion that____.A. human news anchors should learn from AT anchors to save their jobsB. Al anchors perform much better than human news anchors at presentC. Al news anchors won't replace human news anchors in the near futureD. Xin Xiaomeng s expressions vary so naturally that they are true to life【答案】（1）B（2）A（3）D（4）C【解析】【分析】本文是一篇说明文，上周日，新华社新闻主播辛晓萌成为世界上第一位女性人工智能新闻主播，作者介绍了人工智能背后的技术，并指出在不久的将来，人工智能新闻主播不会取代人类新闻主播。

When athletes at the 2020 Tokyo Olympics collect their medals, they'll not only be wearing something that celebrates their sporting performance, but something that symbolizes lastingness. For both the 2020 Olympics and Paralympics, organizers aim to make all of the gold, silver, and bronze medals out of used electronics. This strong message about how to make use of e-waste has gotten a lot of Japan involved.Starting in April 2017, the Japanese Olympic Committee began collecting old laptops, digital cameras, smartphones, and other abandoned electronics. The initiative (倡议) has achieved great success. Already, the quantity needed for bronze medals has been met, and they're in the homestretch for silver and gold medals, meaning the collection process can pack up at the end of March.When looking just at the number of cell phones collected, the amount of waste is shocking. In a period of about 18 months, a little over 5 million smartphones were collected thanks to cooperation with NTT DOCOMO. Japan's largest mobile phone operator allowed the public to turn in phones at their shops, which counted a lot in the project's success.After being taken apart and sorted, the small electronics underwent a smelting process to extract (提炼) all the gold, silver, and bronze elements. Thanks to this initiative, the worldwide struggle with e-waste will have a global platform. According to a study published by the United Nations University—44.7 million metric tons of e-waste were made in 2016. Only 20% of that was actually recycled. Unfortunately, this figure is set to rise significantly in the coming years, moving to 52.2 million metric tons by 2021. So while the Tokyo Olympics initiative might be just a drop in the bucket, it's a good start in showing what the public can do if they're made more aware of the issue.（1）What can be learnt about Tokyo Olympics initiative from the passage?A. E-waste in the world is increasing significantly.B. It is easy to get elements needed from the used electronics.C. Only producers of electronics participated in the project.D. NTT DOCOMO contributed to the success of the project.（2）Which can best replace the underlined word "homestretch" in Paragraph 2?A. starting periodB. collection effortC. final stageD. hard search（3）What influence does the Tokyo Olympics initiative have?A. It offers an effective method to solve the problem of e-waste.B. It shows the power of advanced technology in daily life.C. It saves the expense spent in making all the medals.D. It encourages the public's involvement in dealing with e-waste.（4）What is the writer's attitude to the Tokyo Olympics initiative?A. PositiveB. NegativeC. AmbiguousD. Indifferent【答案】（1）D（2）C（3）D（4）A【解析】【分析】本文是一篇说明文，介绍了日本将回收利用废弃的电子产品中的金属，用于制作2020年奥运会奖牌。

【英语】英语阅读理解(科普环保)题20套(带答案)及解析一、高中英语阅读理解科普环保类1．犇犇阅读理解The Alexander techniqueUntil earlier this year, I didn't know anything about the Alexander technique—and saw no reason to think I should. One day, the backache I regularly suffered was more painful. I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they'll go away, but I eventually went to the doctor. After examining me, he said, "You actually have bad posture (姿势). Go off and learn the Alexander technique." Three months later I could walk straighter and sit better.The Alexander technique is a way of learning how you can get rid of harmful tension in your body. The teaching focuses on the neck, head and back. It trains you to use your body less severely and carry out the movements that we do all the time with less effort. There is little effort in the lessons themselves, which sets apart the Alexander technique from yoga or pilates, which are exercise-based. A typical lesson involves standing in front of a chair and learning to sit and stand with minimum effort. You spend some time lying on a bench with your knees bent to straighten the spine (脊椎) and relax your body while the teacher moves your arms and legs to train you to move them correctly.The technique helps to break the bad habits accumulated over years. Try folding your arms the opposite way to normal. This is an example of a habit the body has formed which can be hard to break. Many of us carry our heads too far back. The head weighs four to six kilos, so any inappropriate posture can cause problems for the body. The technique teaches you to let go of the muscles holding the head back, allowing it to go back to its natural place on the top of our spines.So who was Alexander and how did he come up with the technique? Frederick Alexander, an Australian actor born in 1869, found in his youth that he had vocal (声音的) problems during performances. He analyzed himself and realized his posture was bad. He worked on improving it, with excellent results. He brought his technique to London and opened a teacher-training school, which is still successful today.So if you're walking along the road one day with shoulders bent forward, feeling weighed down by your troubles, give a thought to the Alexander technique. It will help you walk tall again.（1）What does the author suggest in Paragraph 1?A. She felt no better after the treatment.B. She got bored with the Alexander technique.C. She was sceptical about the doctor's method.D. She was unwilling to seek treatment for her backache.（2）What is the principle of the Alexander technique?A. Physical tension shouldn't be completely relieved.B. The technique shouldn't be combined with other exercises.C. The practice of the technique shouldn't be attempted alone.D. Familiar physical actions shouldn't be done with much effort.（3）What can we learn about Frederick Alexander?A. He managed to recover his vocal powers.B. He was eager to make a name for himself.C. He developed a form of exercise for actors.D. He had to leave home to develop his technique.（4）What is the main idea of the passage?A. The occurrence of back pain is widespread.B. Alexander improved the technique to treat body pain.C. The Alexander technique helps overcome posture problems.D. People with back pain are victims of inappropriate postures.【答案】（1）D（2）D（3）A（4）C【解析】【分析】本文是一篇说明文，介绍亚历山大技巧的对于矫正身体的作用以及其发明者。

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 basedon 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 wereto 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 likelyto 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 notgo 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. Robot Saved, People Take the HitD. Humanized Robots, Replace Human【答案】（1）B（2）A（3）B（4）C【解析】【分析】本文是一篇说明文，随着越来越多的机器人具有人性化，它们承担越来越多样化的专业和日常任务，人们如何看待他们，如何对待他们的问题变的迫在眉睫。

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。

When you think back to the blackboard from your school days, what color is it? Chances are that it's green. So what's up with the name? Originally, blackboards were really black. Before wall-sized blackboards existed, late 18th-century students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones.In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn't draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. Problem solved! From there, the idea spread quickly as teachers could finally show a concept to the whole class at one time. By 1815, the massive writing spaces were common enough to earn their own name: blackboard.The color change came in the 1960s when companies sold, steel plates, coated with green enamel (漆) instead of the traditional dark slate. The new material was lighter and less fragile than the first blackboards, so they were cheaper to ship and more likely to survive the journey. Teachers weren't complaining either. After all, the new "greenboards" made the chalk powder easier to erase. Plus, the enamel left less of a glare and the color was nicer to look at. At that point, people started using the word "chalkboard "as a more accurate descriptor, but "blackboard" still stuck around.（1）What did the late 18th-century students use in class?A. Blackboard.B. Chalkboard.C. Greenboard.D. Mini board.（2）Why did the headmaster ask the students to put their mini boards together?A. To make a comparison.B. To make enough space.C. To draw students' attention.D. To arouse students' interest.（3）Which of the following is NOT the advantage of the "greenboard"?A. They're lighter in weight.B. They're more convenient to transport.C. They're easier to erase the powder.D. They're more useful than the traditional ones.（4）What's the main idea of the text?A. Introduction of the blackboard.B. Origin of the blackboard.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.

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。
