Unit 4 Text A Drone Trends to Watch in 2018
Drone-Enabled Big Data
Several companies are already using drones for data collection and analysis in such areas.
Drone-Enabled Big Data
With copious amounts of data to power unmanned aerial vehicles, “smart drones” will become more adept at navigating hazards on their own and communicating amongst themselves to negotiate safe flight paths, alter routes automatically in real-time according to current conditions, and even abort missions altogether if the data shows too much risk.
Flyability公司开发了Elios,这是一种检测无人机,旨在探索室内 和密闭空间,以指导从桥梁到矿山等任何地方的安全改进。
Drone-Enabled Big Data
Data collected by drones will also help the drone industry itself. 无人机收集的数据也将有助于无人机行业本身。
New Capabilities
Drones will have improved camera technology, upgraded Global Navigation Satellite System (GNSS), ultra-fast charging, and longer-lasting batteries.

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现:地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明,地球上的许多生态系统都达不到标准。
The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出,由于不可持续的使用,地球上将近三分之二的用来维持生命的生态系统(包括干净的水源、纯净的空气以及稳定的气候)正遭受破坏。
Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。

新西兰企业家开发了一款机器海豚——2022年高考英语最新热点时文阅读含语法填空、七选五、阅读理解
2022年高考最新热点时文阅读-科学新知2题型主要内容1阅读理解实验证明:比起使用数字设备,在纸上写作实际上对大脑最有益2阅读理解新西兰企业家开发了一款机器海豚,将为海洋馆提供新的选择3阅读理解家里的冰箱里存放的东西反映人的性格4阅读理解莫扎特效应有利于孩子大脑的发育01(2022·安徽·合肥市第八中学高二期末)A team from the University of Tokyo just published a new study that says that writing on paper is actually the best for your mind. “Paper is more advanced and useful compared to electronic records because paper contains more one-of-a-kind information for stronger memory recall,” said Professor Kuniyoshi L. Sakai, a neuroscientist at the University of Tokyo and author in the study.Most people like smartphones or tablets because they seem to make everyday tasks easier, but after gathering 48 volunteers between the ages of 18 and 29 for the study, the researchers found that those who wrote on paper to finish note-taking tasks completed these 25 percent faster than people who used smartphones or tablets. What is the reason? The team said that using paper gave the volunteers more of a chance to write in their own form, while digital devices (数字设备) are more consistent (始终如一的).The researchers divided the volunteers, including college students and office staff, into three groups depending on their memory, preferences for using paper or digital tools, sex and age. Then each volunteer read a conversation that highlighted characters explaining their plans, which mentioned what they wanted to do in two months, their 14 different class times, the deadlines for the characters' homework, and any other things. After using their paper or a device to take notes about this conversation, the volunteers were given an hour break and at ask to keep them from thinking directly about the study. They were then asked a number of questions like “What are the deadlines for the characters’ homework?”Those who used paper for notetaking took only 11 minutes to jot down their thoughts during the study, while people who used tablets took 14 minutes; smartphone users spent the most time on the task, taking 16 minutes to write down their thoughts. As for the accuracy of the answers, those writing on paper seemed to stand out. This suggested that writing on paper benefited their memory.1.Why did the volunteers writing on paper finish note-taking tasks faster?A.Their tasks were less difficult.B.They took notes without any stops.C.Their writing styles were consistent.D.They could write in their unique ways.2.What were the volunteers required to do in the study?A.Make up some conversations.B.Raise questions for each other.C.Take notes about a conversation.D.Discuss notes with group members.3.Why were the volunteers asked to answer questions after a break?A.To test their memory.B.To ensure the accuracy.C.To keep them energetic.D.To remove their thoughts.4.What does the underlined phrase “jot down” in the last paragraph probably mean?A.Leave out.B.Write down.C.Break down.D.Concentrate on.02(山西省吕梁市2021-2022学年高三上学期第一次模拟考试英语试题)Companies in New Zealand are working with American creators of some of Hollywood’s most famous creatures to develop animatronic dolphins that look almost the same with their living counterparts.A robotic dolphin that can nod an answer to a child might sound unappealing. But as marine parks around the world face increasing pressure to abandon exhibitions featuring real whales and dolphins, the creatures provide an appealing alternative, their creators say.But with a price tag of about NZ$40m (£ 20.8m) per dolphin, the biggest obstacle for the creators of the animatronic creatures is proving to potential clients that the robotic sea creatures will work out to be cheaper in the long run than the real thing.Li Wang, a business developer for Edge Innovation, the New Zealand-based company making the case for the robots, said they do cost four times more than normal dolphins but would last longer.Melanie Langlotz, one of the managers behind the project said, the robotic dolphin can’t be distinguished from the real thing. A test audience had been unable to guess the dolphin was not real, she added.Animal rights advocates also welcomed the change. They hoped robotic dolphins would replace real ones in marine parks worldwide.In nature, dolphins swim up to 40 miles a day and live in close family groups, but in captivity they were confined to concrete pools filled with chemically treated water and forced to interact with strangers. In the near future, cutting-edge technology might allow us to experience nature without harming it.5.Why will animatronic dolphins be developed?A.To attract children.B.To make a higher profit.C.To protect real dolphins.D.To show the advance of technology. 6.What can we know about robotic dolphins according to the text?A.They look different from the real ones.B.They are appealing to marine parks as well as children.C.They would have a shorter lifespan compared to real ones.D.They would be more expensive but survive longer than real ones.7.Why does the author mention real dolphins in the last paragraph?A.To stress the significance of robotic dolphins.B.To inform us of bad conditions of dolphins in captivity.C.To clarify why dolphins live better in natural environment.D.To suggest that we should improve the living conditions of dolphins.8.What’s the best title for the passage?A.Dolphins: cute animals to play withB.Robot dolphins: a costly but worthy alternativeC.Robot dolphins: an attractive and affordable toolD.Advanced technologies benefit the environment03(2022·四川·凉山彝族自治州教育科学研究所高一期末)If you don’t want people to know much about you, you’d better keep your fridge contents secret, according to a British market research document released last week.Researchers studied the fridges of 400 people in Britain and compared the contents with the owners’ lifestyles. They claim to be able to classify the nation’s people by fridge contents. They say those people can be separated into five categories: nutrition nerds (痴迷者), food -trend chasers (whatever is fashionable), strict mums, fast food fans and restaurant regulars.Nutrition nerds care much about what they put into their bodies. Their fridges are filled with fruit, vegetables and healthy meat. People in this category tend to be highly organized and usually work as lawyers or accountants (会计). The majority of them are single, but if they have a partner, that person will be similar.A fridge full of vitamins—enriched juices shows its owner works in media or fashion. They tend not to eat the foods they buy. Known as the food -trend chasers, they just want to be seen buying the latest important things.A fridge filled with everything from steak to frozen fish suggests the strict mum. Her fridge tends to be filled with every kind of product, except what she herself wants. This fridge shows difficulty in balancing family and work life.Fast food fans always buy mineral water or soda pop. The nearest they will get to fresh fruit is tomato sauce. Their fridges show someone who works hard and plays hard, and someone who doesn’t like long term planning.9.What did the researchers find out?A.People in Britain like to eat out.B.Most British people don’t eat healthily.C.There are five types of people in the world.D.People’s characters can be reflected by their fridge contents.10.What can you infer about nutrition nerds?A.They rarely eat meat.B.They are mostly single.C.They care about food quality and expenses.D.Their lives are organized by lawyers or accountants.11.What do we know about the five types of people?A.Nutrition nerds are always organized and successful in their jobs.B.Strict mums care about others in family more than themselves.C.Food- -trend chasers like to fill their fridges with tasty foods.D.Fast food fans usually fill their fridges with fresh fruit.12.What will those who often eat out put in the fridge?A.Food rich in vitamins.B.Only something to drink.C.Fast food with tomato sauce.D.Food from restaurants.04(2022·广东·高二期末)You may have heard about Amadeus Mozart, a classical composer from the 18th century. But have you ever heard about the Mozart effect?The Mozart effect first came to be known to the public in 1993. A study published in the journal Science found that children who listened to Mozart’s music, for ten minutes showed a clear improvement in spatial (空间的) reasoning tests than those who listened to other sounds that can help people relax. Another study also examined the long-term effects of Mozart on the brains of kids. A group of 3- to 4-yeard-old kids were given music lessons for six months. After the lessons, the performance of the kids on a spatial reasoning test saw 30 percent improvement as compared to children who undertook other training or no training at all for that long.As a result of these studies, the popularity of Mozart’s music has grown. Some schools in the US started to play Mozart to children, and it even led the southern state of Georgia to provide babies with free Mozart CDs. And the findings further showed the importance of music in the cognitive development of children.Now we know the Mozart effect shows playing Mozart benefits brain development. But how does that happen? The classical music pathways in the brain and the neural (神经的) trails we use for spatial reasoning are quite alike. When we listen to classical music or learn to play this kind of music, especially Mozart’s music, the spatial pathways in the brain are stimulated (刺激) and prepared for use. This makes the mind more active, leading to more intelligence.As parents, you do not need to wait until your kid is in primary school to start music lessons. Most children between the age of four and five are ready to start learning the basics of music. Early intervention (干预) can help your baby grow into a smart adult, besides improving his or her academic performance and life skills.13.What can we learn about children listening to Mozart’s music?A.They show great interest in creating music.B.They could perform spatial tasks better.C.They find his music difficult to understand.D.They could hold their attention much longer.14.The author introduces the Mozart effect mainly by ________.A.explaining data B.stating argumentsC.providing research results D.analyzing experts’ words15.Why is classical music beneficial to brain development?A.It makes the mind calm and clear.B.It fixed some damage to neural trails.C.It helps awaken some hidden memories.D.It causes the brain’s spatial pathways to start to work.16.What are parents advised to do to help their children be smart adults?A.Train children to form good learning habits.B.Develop an interest in music themselves.C.Perform music with children as much as possible.D.Get children to start music lessons early on.参考答案:1.D2.C3.A4.B【分析】这是一篇说明文。

一、阅读理解ChatGPT is back in the headlines (新闻头条)! OpenAI, the pany behind the popular chatbot, has now introduced a powerful new language model: GPT4.On March 14, GPT4 showed the world how smarter it is than the previous GPT3.5.One of its best new features is that it can understand pictures. For example, if you show a picture of a phone using the wrong charger (充电器), GPT4 can tell why the picture looks strange or funny.But GPT4’s developments don’t stop there. The new language model can code (用代码编写) classic games like Tetris (俄罗斯方块) in a matter of minutes, and produce the code and layout (布局) for a website based on a handmade drawing. It can also change the tone (语气) and style based on what you ask it to do. GPT4 is much better than the older GPT at passing tests, which may worry teachers. According to CNN, GPT4 did really well on a law school test, with a score in the top 10 percent of test takers. But GPT3.5 only got a score in the bottom 10 percent.GPT4 will also see greater use as a tool to power other apps and services. For example, the language learning app Duolingo plans to use GPT4 in their uping (即将到来的) Duolingo Max function (功能). Users can learn language by talking with AI. Another app, Be My Eyes, will have a digital assistant (数字助手) to help blind people better understand the world around them. The government of Iceland also plans to use GPT4 to protect the Icelandic language.There are still problems with the new language model, however. GPT4 still struggles to get pletely correct answers, especially wi th newer information after September 2021. GPT4 also sometimes “hallucinates (产生幻觉)”, meaning that it will insist that wrong information is true.1. What can we infer from Paragraph 2?A. GPT3.5 cannot understand pictures.B. GPT4 can respond in a fun way.C. GPT4 can tell if a phone is recharging.D. GPT4 can create funny pictures.2. The phrase “in a matter of minutes” in paragraph 3 shows that _____.A. games like Tetris are easy to codeB. GPT4 can code games like Tetris quicklyC. handmade drawings help GPT4 work betterD. anyone can code games using GPT43. What worry does GPT4 bring to teachers?A. It can change tones based on a user’s input.B. It may help students cheat on tests easily.C. Students will lose their petitiveness.D. It will take the place of lawyers in the future.4. How will the Duolingo Max users benefit from GPT4?A. AI can help them make personalized study plans.B. Blind people can municate through the app.C. They can practice languages by talking with AI.D. They can find many dying languages on the app.5. What does GPT4 “hallucinates” mean?A. It is stuck in the time before Sept 2021.B. It may not tell the past from the present.C. Its answers are partly right and partly wrong.D. It responds with wrong information.【答案】ABBCA【解析】本文介绍新版GPT4具有更加强大的功能。

SUBMERGED ARC FURNACE TECHNOLOGY
The main features of a submerged arc furnace smelting chromite are shown in Figure 1. These include: 3-phase 3-electrode A.C. operation Soderberg electrodes choke feed with overburden of chromite, reductants and fluxes energy generation by electric resistance heating controlled by secondary voltage and electrical resistivity of burden and slag electrical resistivity of burden determined mainly by size and type of reductant, e.g. coke (Iow resistivity) versus coal (high resistivity). electrical resistivity of slag determined by its composition. Close control of the charge composition and its sizing, and of the slag composition, are essential for effective operation of the submerged arc furnace. For example, three important slag properties are determined by its composition: slag viscosity: determines physical separation and recovery of metal from slag, and high viscosity slags can cause foaming problems in furnace operation. slag resistivity: helps determine electrode penetration and power input to the furnace with more resistive slags allowing deeper penetration, higher voltage operation and greater power inputs. slag liquidus : determines overall operating temperature and degree of superheat to the melt.

The strengths of the submerged arc furnace for smelting chromite may be defined as: Relatively easy to control provided the charge is well classified to maintain a 1. permeable overburden and allow escape of reduction gases, and provided also that the charge composition is well calculated and remains constant to maintain steady state electrical conditions and target slag composition. Self regulating, with power input determining rate of consumption of 2. overburden. Some preheating and pre-reduction of the overburden by the hot, ascending 3. reaction gases. Weaknesses are: 1. Requires lump ore or agglomerated ore fines for maximum operating efficiency and maximum chromium recovery. This is an important factor, for example, in South Africa where approximately 70 per cent of the chromite mined is produced as fines. Agglomeration by pelletising or briquetting is costly and may not be entirely effective in furnace operations. 2. High cost coke is required as a reductant mainly to achieve correct electrical resistivity in the burden. Coal can be used in part to adjust resistivity but there may be problems with evolution and combustion of volatiles above the burden, with consequent overheating of the furnace superstructure. 3. Furnace operation and metallurgical control is dictated by the quality and physical form of the charge, and by the slag composition. 4. Slow and diluted response to deliberate changes in charge composition. 5. 6. Chromium recoveries range from poor (65%) with high fines usage, to moderate (80%) (Figure 2). Waste-gas utilisation not practical unless the furnace is closed.
ABSTRACT The production of chromium units as ferrochromium alloys is dominated by the submerged arc furnace. Submerged arc smelting of ferrochromium is now a mature technology where improvements to decrease costs are becoming increasingly difficult. Thus some ferrochromium producers are introducing new technologies to be more cost effective and to produce better products. These developments are continuing and this paper charts the course of the more important of these and probable future trends. Included are D.e. plasma smelting, pre-heating and prereduction processes, and processing units such as the rotary kiln, rotary hearth furnace and fluid-bed reactor. The possible elimination of electrical energy is raised in a section on coal/oxygen based, smelt-reduction processes with some examples. Finally, the question of 'direct stainless steel' is discussed with its implications for the future supply of ferrochromium.
INTRODUCTION The smelting of chromite ores is dominated by the electric submerged arc furnace and it has become entrenched as the recognised production unit for ferrochromium alloys. Nevertheless, it does have some significant limitations in the smelting of chromite. These limitations, coupled with the fact that as a technology it can be regarded as having reached the 'mature' phase of its evolutionary development, require ferrochromium producers and their main customers, the stainless steel producers, to take a hard look at more cost and quality effective production and supply of chromium units. The objective of this paper is to outline some of the current and possible future developments in high carbon ferrochromium and charge chrome production, the reasons for these developments and their perceived strengths and weaknesses; and to look also at possible threats to ferrochromium production in the supply of chromium units to stainless steel producers by other means.
