经济学人原文Making trouble:UK needs an industrial strategy to compete in manufacturing【1】Countries that are serious about manufacturing have industrial strategies.The US and China have one. So do Germany and France. Britain does not . Rishi Sunak talks about turning the UK into a “science and technology superpower” but that’s all it is: talk. It is a PR strategy masquerading as an industrial strategy.【2】Faced with the challenge presented by Joe Biden’s inflation reduction act (IRA), the government says it has no need to respond to the package of green subsidies being provided by Washington because Britain has already established a thriving renewables sector and the Americans are playing catch up. The complacency is staggering.【3】Andy Haldane , once the Bank of England’s chief economist and now the chief executive of the Royal Society of Arts, last week said: “The world is facing right now an arms race in re-industrialisation. And I think we’re at risk of falling behind in that arms race unless we give itthe giddy-up.”【4】China, Haldane added, had been focusing on green technology for many, many years and had forged ahead in tech such as solar and batteries. “The west has belatedly woken up,” he said. “The IRA is throwing cash to the wall on that. The cost of that [is] almost certainly north of half a trillion dollars. Possibly north of $1tn. The EU is now playing catch up, [and] the UK currently is not really in the race at any kind of scale.”【5】A quick glance at the latest trade figures shows Britain has some way to go to be a manufacturing“superpower”.manufacturing’s share of the economy shrank from more than 30% to less than 10% of national output in Elizabeth II’s reign. The goods deficit, last in surplus in the early 1980s, stood at £55bn in the first three months of this year, with imports more than 50% higher than exports. A £40bn quarterly surplus in services was not enough to close the trade gap.【6】Those who supported Brexit say the UK now has the freedom to export more to faster growing parts of the world economy . Those who opposed it say exporting to the EU has become more burdensome. Both are right, but both are missing the point. Before Britain can take advantage of export opportunities it has to have stuff to export. The fact is the UK is no longer a firstrank manufacturing economy and hasn’t been for decades.【7】Dyson’s recent announcement that it will build a battery factory in Singapore is a perfect illustration of the challenge facing the UK. There was never the remotest possibility that the plant would be in the UK due to what its founder James Dyson, a prominent Brexit supporter, called in a letter to the Times, t he “scandalous neglect” of science and technology businesses.【8】Only part of the company’s reluctance to manufacture in the UK is due to the recent jump in corporation tax, though that wipes out any benefit from tax breaks for research and development. It is also the planning system, the lack of trained engineers, the disdain shown for science and technology, and government interference in the way businesses are run.【9】The company says the UK will remain a centre for R&D, and it will invest £100m in a new tech centre in Bristol for software and AI research. But the idea that Britain can do all the high-value brain power stuff while other countries do the production is an illusion. Increasingly, Dyson’s R&D happens in Singapore, the site of its global HQ, and in the Philippines.【10】Dyson is by no means alone. A report by the lobby group Make UK found that six in 10manufacturers thought government had never had a longterm vision for manufacturing, while eight in 10 considered the absence of a strategy put their company at a competitive disadvantage compared with other manufacturing nations. It is no surprise that AstraZeneca recently announced it was building its new factory in Ireland .【11】Stephen Phipson, Make UK ’s chief executive , said last week the US was spending 1.5% of national output on its IRA. The equivalent sum in the UK would be £33bn. It was not just the money, though. “A lack of a proper, planned industrial strategy is the UK’s achilles heel ,” Phipson said. “Every other major economy, from Germany, to China, to the US, has a long-term national manufacturing plan, underlying the importance of an industrial base to the success of its wider economy. The UK is the only country to not have one.“If we are to not only tackle our regional inequality, but also compete on a global stage, we need a national industrial strategy as a matter of urgency.”【12】One option is to concentrate instead on sectors where the UK does have global clout: financial and business services, for example. In that case, the pretence has to stop that levelling up will be delivered by new factories turning out world-beating products.The government can either make Britain an attractive place for manufacturing companies to invest or it can decide not to compete. Judged by its actions rather than by its rhetoric, it seems to have chosen the latter option.。

东西面Adjustable shading is particularly useful for eastern and western elevations, as the low angle of the sunmakes it difficult to get adequate protection from fixed shading. Adjustable shading gives greater controlwhile enabling daylight levels and views to be manipulated.Appropriate adjustable systems include slidingscreens, louvre screens, shutters, retractable awnings and adjustable external blinds.对于东西立面可调节式遮阳是非常重要的,因为太阳的入射高度角低,使固定的遮阳设备很难达到一个准确的支出角度。
关于堤防的英语作文
关于堤防的英语作文Levees are critical infrastructures designed to protect communities from the devastating effects of floods. They are constructed along rivers, lakes, and coastal areas to prevent water from overflowing and damaging property and lives.Here's a closer look at the significance of levees and their role in safeguarding our environment and society.Construction and DesignLevees are engineered structures typically made of earth, concrete, or a combination of materials. They are built to withstand the pressure of water during high tides, storms, and heavy rainfall. The design of a levee must consider the height, width, and slope to ensure stability and effectiveness against water forces.Environmental BenefitsOne of the primary environmental benefits of levees is flood control. By containing water within the riverbanks, levees prevent flooding that can lead to soil erosion and loss of wildlife habitats. They also protect agricultural lands, which are vital for food production.Economic ImpactThe economic benefits of levees are substantial. Theysafeguard property and infrastructure, reducing the need for costly repairs and reconstruction after a flood. Additionally, they protect industries and businesses that are located in flood-prone areas, ensuring economic stability and continuity.Community SafetyLevees play a crucial role in community safety. They providea physical barrier that can save lives by preventing floods from reaching residential and commercial areas. In the eventof a flood, the presence of a levee can give residents timeto evacuate to higher ground.Challenges and MaintenanceDespite their benefits, levees also present challenges. They require regular maintenance to remain effective, whichincludes monitoring for erosion and reinforcing the structure as needed. Additionally, levees can sometimes lead to complacency, causing people to underestimate the risk of flooding.ConclusionIn conclusion, levees are an essential component of flood management strategies. They protect the environment, support economic stability, and ensure the safety of communities. However, it is vital to maintain and monitor these structures to ensure their continued effectiveness. As climate change continues to impact weather patterns, the role of levees in flood prevention will become increasingly important.。

2023年高考英语外刊时文精读专题03看到空中的碳足迹
2023年高考英语外刊时文精读精练 (3)Carbon emissions碳排放Seeing footprints in the air看到空中的碳足迹主题语境:人与自然主题语境内容:环境保护【外刊原文】(斜体单词为超纲词汇,认识即可;下划线单词为课标词汇,需熟记。
)Chris Jones of the University of California, Berkeley, was on a river in the Amazon rainforest when he put th e finishing touches on the world’s first online household carbon calculator(计算器). That was in 2005. He hoped that, if he could show people how much greenhouse gas was associated with daily activities—driving the car, heating the house—they might change their behaviour and contribute in some small measure to saving the Amazon. Seventeen years later, trackers are providing a wealth of often-neglect ed information about the carbon emissions of everyday life. They provide local and micro data which usefully supplement the global findings of the Intergovernmental Panel on Climate Change.Trackers work by asking users to answer questions such as: how many miles a year do you drive; how much is your annual household electricity bill; how often do you eat meat? They then calculate a personal or household estimate of emissions of carbon-dioxide equivalent (CO2e,二氧化碳当量排放量) per year. Alex Beale, a climate blogger in Atlanta who has studied them, reckons there are dozens of household carbon trackers and hundreds of specialist ones, including those which calculate emissions from food or other industries, such as a new one from the Stockholm Environment Institute (SEI) to track emissions from shipping. For individuals, reckons Mr Beale, the most comprehensive are the Cool Climate tracker run by Dr Jones at Berkeley and the calculator set up by the World Wildlife Fund (WWF) and SEI. What do they tell us?Dr Jones describes the main household polluting activities as “cars, coal, cows and consumption,roughly in that order”.By far the largest single source of emissions is the family vehicle. One car of average fuel efficiency driven 14,000 miles (22,500km) spews out 7 tonnes of carbon, according to Dr Jones’s tracker. Swapping it for an electric vehicle would save over 6 tonnes, or an eighth of the average American household’s yearly emissions.No other change would generate that much saving, though electricity in the homeis responsible for over 5 tonnes of carbon emissions a year, so generating it with solar panels(太阳能电池板) would come close . Like electric vehicles, a roof full of solar panels is not cheap. Changing diets costs less, and American households consume meat worth 2.7 tonnes of CO2e a year, far more than most people. If Americans went vegetarian(素食者), that would be like half an average solar roof.These household averages, however,disguise what may be the most important thing carbon trackers reveal: that apparently similar households produce very different emissions. By combining their tracker’s results with postal(邮政的)code data, the University of California team worked out average emissions by area. Places with high emissions—mostly suburbs(郊区)—produce four or five times as much carbon as inner cities or rural areas, a much larger multiple than might have been ex pected. Chicago’s households produce37 tonnes of CO2e a year; suburban Eola’s, some35 miles (56km) from the Windy City, emit96 tonnes. This is not only because of commuting(通勤). Trips to and from work account for less than a fifth of miles driven; the rest are to shops, schools and so on.Even more striking is the difference air travel makes. The average household contribution from flying is 1.5 tonnes, less than a car. But half of Americans never fly. According to Cool Climate, flying 100,000 miles a yearproduces a stunning(惊人的)43 extra tonnes of CO2. If jet-set households were to cut their travel sharply, they would have a disproportionate(不成比例的)effect on emissions. They might even do something for the Amazon.Over the next 30 years, many countries are promising to move to net-zero carbon, imply ing that household emissions will have to be cut to close to nothing. Stephanie Roe, WWF’s lead climate scientist, reckons that, at best, half the reduction might be achieved through demand-side measures, such as behavioural changes by individuals and households. And even that would require companies and governments to provide more incentives(激励)to change through supply-side investments to make low-carbon options cheaper and more widely available.Trackers, it seems, have daunting(令人怯步的)lessons for public bodies and private households alike.【课标词汇】1.associate将…(与…)联系起来,把…联系在一起Most people associate this brand with good quality.大多数人把这个品牌和优良品质联系在一起。
高一英语阅读理解强化训练附解析Day 121
高一英语阅读理解强化训练附解析Day 121Passage 1The victims were carried in one by one, their paws burned and fur burnt, suffering from dehydration (脱水) and fear. Their caretakers bandaged (用绷带包扎) their wounds and laid them in baskets with the only thing that was familiar — the leaves of a eucalyptus (桉树) tree. As fires have burned more than two million acres in Australia, dozens of koalas have been rescued from burned trees and pale ground. The animals are being treated in rescue centers, and at least one private home, along the country’s east coast.The difficult situation of the koala — a national symbol of Australia — has raised questions among environmentalists and scientists about what it will take to protect biodiversity (生物多样性) in a country with intense fire, extreme heat and lack of water. Australia has already been among the highest rates of species extinction in the world.The bad situation goes beyond koalas. Recently, tens of thousands of bats fell from the sky in temperatures over 107 degrees Fahrenheit in northern Australia. Kangaroos destroyed the grapes in Canberra because of drought.“Climate change and other human impacts have so changed the situation that the government needs to rethink its way to protect at once,” Dr. Bowman said, suggesting interventions (干预) like irrigating, feeding and moving animals to new places.Koalas, unlike kangaroos, birds or snakes, do not escape from fires. Therefore, though the fires are still burning, a rescue team began to search the area carefully. Walking in a human chain, they looked up to the tree top, searching for survivors.1. What do the victims in the first paragraph refer to?A. Animals injured in fires.B. Kangaroos driven by drought.C. Bats that fell from the sky.D. Koalas rescued from the fire.2. Which of the following may cause the extinction of wildlife?A. Wildfires that seldom happened.B. Extreme hot weather in Australia.C. The never-changing climate in Australia.D. Not having enough money to take measures in Australia.3. What can we draw from Dr. Bowman?A. Human activities have little influence on animals.B. The government should take immediate action.C. The government does not care about the wild animals.D. Scientists are concerned about the bad situation of wildlife.4. What’s the best title for the text?A. Saving the Fire Victims Who Cannot Escape: Australia’s KoalasB. Saving the Endangered Wild Animals in AustraliaC. Actions Needed to Protect Habitat for KoalasD. National Symbol of Australia Needs RescuePassage 2While traveling alone has some disadvantages, it’s well worth the journey. And, if you’re looking for some travel inspiration on international destinations that are perfect for solo traveling, we’ve got your four.Canada is well-known for being one of the friendliest countries in the world. Eat your way through Toronto and test your fear of heights walking 116 stories above the ground on the CN Tower’s Edge Walk. Traveling in Canada is easy, safe, and dynamic.Amsterdam’s canal ring is on the UNESCO World Heritage list. In the warmer months, you’ll want to visit the flea markets, parks, and dine alfresco. You’ll be amazed to find there are more bicycles than there are people in Amsterdam.Nature enthusiasts will find much to explore in Iceland, a country full of volcanoes and glaciers (but a lack of forests! ). Tour the Golden Circle and visit the famous Blue Lagoon. Iceland is one of the safest countries in the world to visit, making it a top choice for this list.Visiting Japan without going to Kyoto would be a big mistake. Gion, Kyoto’s geisha district, is highlight. You’ll see Zen gardens, temples, and sake bars as well as casual Japanese bars.Costa Rica is known for its tropical beaches and rich forests. It’s an adventurer’s dream place, with lots of hiking, surfing, and boating opportunities. Costa Rica is a safe country to visit, outside of the possible sun burn, and you may experience the Pura Vida lifestyle that the country is known for.1. Which is the best place to test your courage?A. The CN Tower’s Edge Walk.B. Kyoto’s geisha district.C. The Blue Lagoon.D. Amsterdam.2. If you want to go to a forest and have adventures, which country should you go?A. Canada.B. Iceland.C. Costa Rica.D. Japan.3. What’s the main purpose of the text?A. To introduce some places in the world.B. To show solo travelers places to visit.C. To describe beautiful scenery around the world.D. To point out some places people should not miss.Passage 3Do you often feel tired? Is it really because of the large amount of mental work you do? Here is an astonishing and significant fact: Mental work alone can't make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳). To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally tireless. So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional attitudes. One of England's most outstanding scientists, J. A. Hadfield, says, "The greater part of the fatigue from which we suffer is of mental origin. In fact, fatigue of purely physical origin is rare. " Dr. Brill, a famous American scientist, goes even further. He declares, "One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems. "What kinds of emotions make sitting workers tired? Joy? Satisfaction? No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated — those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.1. What surprised the scientists a few years ago? ________A. Fatigue toxins could hardly be found in a laborer's blood.B. The brain could work for many hours without fatigue.C. Albert Einstein didn't feel worn out after a day's work.D. A mental worker's blood was filled with fatigue toxins.2. According to the author, which of the following can make sitting workers tired? ________A. Unpleasant emotions.B. Challenging mental work.C. Endless tasks.D. Physical labor.3. What's the author's attitude towards the scientists' ideas? ________A. He doubts them.B. He argues against them.C. He agrees with them.D. He hesitates to accept them.4. We can infer from the passage that in order to stay energetic, sitting workers need to________ .A. discover fatigue toxinsB. have some good foodC. exercise regularlyD. enjoy their workPassage 4①From self-driving cars to deep sea explorers, more and more of humans' tasks are being taken over by robots. But technology doesn't stop there. In mid-August, reported the BBC, scientists from Cambridge University developed a robotic system that meant a robot could "build other robots, each one better than the previous (以前的) generation".②The BBC noted that "those concerned about machines taking over theworld shouldn't worry".③However, over 1, 000 scientists and numerous artificial intelligence (AI, 人工智能) researchers—including UK astrophysicist Stephen Hawking and Apple cofounder Steve Wozniak of the US-brought the danger of fully autonomous weapons (自主武器), known as "killer robots", to our attention earlier this summer.④"If any major military (军事的) power pushes ahead with AI weapon development, a global arms race is inevitable (不可避免的), " warned an open letter released at the International Joint Conference on Artificial Intelligence held in Buenos Aires, Argentina.⑤Unlike drones (无人机), which need a human hand, this kind of robot would have some decision-making abilities and the ability to act by itself. While what the BBC called these "soldiers that never sleep" could help reduce battlefield deaths, they might also make countries more likely to go into battle, which would lead to more deaths overall, noted the scientists. The risks, they said, could be far greater than those posed by nuclear weapons.⑥Scientists called for a "ban on offensive (攻击性的) autonomous weapons beyond meaningful human control", reported The Huffington Post.⑦In fact, in an interview with the BBC in 2014, Hawking warned that the "development of full artificial intelligence could spell the end of the human race".⑧And according to the BBC, many leading thinkers have been thinking about the AI-powered killing machine of the not-too-distant future. "Killer robots could be here within years, not decades, " as Stuart Russell, professor of computer science atUC Berkeley, US, put it.⑨Authorities are gradually waking up to the risk of robot wars. Last May, for the first time, the United Nations brought governments together to begin talks on so-called killer robots in a hope of stopping such weapons while there is still time.⑩Meanwhile, there are scientists who are less worried. They believe all technologies have potential (潜力) for being used for good and evil ends, and argue that the ban called for by the open letter could close the door to developing AI technology that could save lives. "Technology can clearly do better than human beings in many cases, " Ronald Arkin, dean at the Georgia Institute of Technology in Atlanta, US, told The Christian Science Monitor. "If we are willing to turn over some of our decision making to these machines, we may actually get better outcomes. "1. What does Steve Wozniak think the future robot technology might produce? ________A. Artificial Intelligence.B. Autonomous weapons.C. Soldiers that never sleep.D. Killing machines.2. The underlined word "spell" in Paragraph 7 is closest in meaning to " ________ ".A. causeB. preventC. reachD. change3. What does Stuart Russell mean by saying "killer robots could be here within years, not decades. "? ________A. Killer robots will visit UC Berkeley, US sooner than expected.B. Killer robots will be produced and used sooner than expected.C. Killer robots will speed up the development of AI in the near future.D. Killer robots will kill these scientists in the near future.4. What is the main idea of the text? ________A. More and more of humans' tasks are being taken over by robots.B. Robots have decision-making abilities and the ability to act by itself.C. Scientists called for a ban on the development of robot technology.D. All technologies have potential for being used for good and evil ends.Passage 5The economy continues to struggle and students are faced with high tuition(学费)costs and an uncertain future when they graduate. In order to make ends meet, some students will turn to credit(信用)cards. However, should college students have credit cards? Across the country, students are getting encouraged to sign up for credit cards. In exchange, they get towels, thin T-shirts and short-term deals on better interest rates. As an educator this does have an effect on me.There is obviously some value in having a credit card while in college. The American financial system is built around building credit. For young people, this is typically achieved by proving that they pay a bill on a regular basis. You would think that people without credit cards would have higher scores, but that is not the case. Therefore, students can start to build a credit history by having a credit card.College is not just about gaining information and learning skills. Higher educationis also about learning responsibility, which is why having a credit card can be a good way to manage a level of independence.For many people, college means some of the best years of life. Relationships and ternaries are built as students enjoy a time of discovery and exploration. Of course, there is the reality that some students spend their college years buying gadgets(小玩意儿), eating out and going to parties. Unfortunately, this is where the credit card can be a dangerous item, as it can be far too convenient to buy entertainment supplies, I love working with college students because they have great potential(潜力), but I also know that they can sometimes make poor choices.I worry that students won't pay their tuition because they have to pay their credit card bill, I would hate for a student to drop out of school because they loaded up the credit card with weekend entertainments. So college students can certainly get credit cards, but they must respect them.1. The underlined phrase “sign up for” in the first paragraph probably means “________ ”.A. prepare forB. apply forC. make up forD. arrange for2. How can students build credit according to this article? ________A. By paying bills regularly with their credit cardsB. By signing up for credit cards successfullyC. By managing a level of independenceD. By being able to pay their own tuition3. It can be inferred from the article that ________ .A. college means great academic achievementsB. students who have credit cards get higher scoresC. college students can sometimes make poor choicesD. owning credit cards may have side effects on students参考答案Passage 11. D细节理解题。
2023年高考英语外刊时文精读专题14气候变化与珊瑚礁
2023年高考英语外刊时文精读精练 (14)Climate change and coral reefs气候变化与珊瑚礁主题语境:人与自然 主题语境内容:自然生态【外刊原文】(斜体单词为超纲词汇,认识即可;下划线单词为课标词汇,需熟记。
)Human beings have been altering habitats—sometimes deliberately andsometimes accidentally—at least since the end of the last Ice Age.Now, though,that change is happening on a grand scale. Global warming is a growing factor.Fortunately,the human wisdom that is destroying nature can also be brought to bear on trying to save it.Some interventions to save ecosystems are hard to imagine andsucceed. Consider a project to reintroducesomething similar to a mammoth(猛犸象) to Siberiaby gene-editing Asian elephants. Their feeding habits could restore the grassland habitat that was around before mammoths died out, increasing the sunlight reflected into space and helping keep carbon compounds (碳化合物) trapped in the soil. But other projects have a bigger chance of making an impact quickly. As we report, one example involves coral reefs.These are the rainforests of the ocean. They exist on vast scales: half a trillion corals line the Pacific from Indonesia to French Polynesia, roughly the same as the number of trees that fill the Amazon.They are equally important harbor of biodiversity. Rainforests cover 18%of the land’s surface and offer a home to more than half its vertebrate(脊椎动物的) species. Reefs occupy 0.1%of the oceans and host a quarter of marine(海洋的) species.And corals are useful to people, too. Without the protection which reefs afford from crashing waves, low-lying islands such as the Maldives would have flooded long ago, and a billion people would lose food or income. One team of economists has estimated that coral’s global ecosystem services are worth up to $10trn a year. reefs are, however, under threat from rising sea temperatures. Heat causes the algae(海藻) with which corals co-exist, and on which they depend for food and colour,to generate toxins(毒素)that lead to those algae’s expulsion(排出).This is known as“bleaching(白化)”, and can cause a coral’s death.As temperatures continue to rise, research groups around the world are coming up with plansof action. Their ideas include identifying naturally heat-resistant(耐热的)corals and moving themaround the world; crossbreeding(杂交)such corals to create strains that are yet-moreheat-resistant; employing genetic editing to add heat resistance artificially; transplantingheat-resistant symbiotic (共生的)algae; and even repairing with the bacteria and other micro-organismswith which corals co-exist—to see if that will help.The assisted evolution of corals does not meet with universal enthusiasm.Without carbon reduction and decline in coral-killing pollution, even resistant corals will not survive the century. Some doubt whetherhumans will get its act together in time to make much difference. Few of these techniques are ready for action in the wild. Some, such as gene editing, are so controversia l that it is doubtful they will be approved any time soon. scale is also an issue.But there are grounds for optimism.Carbon targets are being set and ocean pollution is being dealt with.Countries that share responsibilities for reefs are starting to act together. Scientific methods can also be found. Natural currents can be used to facilitate mass breeding. Sites of the greatest ecological and economical importance can be identified to maximise benefits.This mix of natural activity and human intervention could serve as a blueprint(蓝图) for other ecosystems. Those who think that all habitats should be kept original may not approve.But when entire ecosystems are facing destruction, the cost of doing nothing is too great to bear. For coral reefs, at least, if any are to survive at all, it will be those that humans have re-engineered to handle the future.【课标词汇精讲】1.alter (通常指轻微地)改动,修改;改变,(使)变化We've had to alter some of our plans.我们不得不对一些计划作出改动。

Further, the transplanted liver in the domestic case had only 10 genes edited to prevent a rejection reaction, fewer than the transplanted hearts and kidneys in the US and UK cases, which shows that domestic medical experts may have developed a methodology that can support the patient's _______(survive) without changing the liver too much.With the gene-editing technology aimed at "cutting" more gene clips that trigger a rejection reaction away from pig organs maturing, the risks of transplanted alien organsbeing rejected will be minimized and the technology will be applied more widely to save lives.第二篇社会:英格兰收养儿童的悲惨故事【经济学人】The sorry story of children in care in EnglandJADE BARNETT learned that she was being moved from foster c are(看护中心) into a children’s home a few years ago when she saw her possessions in the back of a taxi. The children’s home turned out ______(be) near Blackpool, in north-west England—330 kilometres from London, where she grew up and where the social workers who were meant to be lookingafter her were based. She expected to stay in the home for two weeks. It turned into one and a half years.Some 84,000 children in England are in the care of local authorities _______their parents cannot look after them for one reason or another. In an extremely centralised(集中的) country, it is one of the few important responsibilities that those _______( institution) still have. Every year councils spend more money on the children in their care. Every year the system serves the country’s most vulnerable children less well.Adult social care, including ________(nurse) homes for the old and frail, is notorious(臭名昭著的) for straining local authorities’ budgets. But spending on children in care is rising ________a faster rate, says Roger Gough, the leader of Kent County Council. In England as a whole, local authorities spent more than £7bn ($8.6bn) on looked-after children in the 2022-23 fiscal year, a 36% increase in real terms ________(compare) with 2015-16. That squeezes budgets for everything else, including help for families not yet in crisis.Over the ten years to 2023 the number of children in care swelled(增加) by 23%, or by 16%if you do not count unaccompanied children seeking asylum(庇护), _______numbers have risen recently. And the children who enter the care system are becoming older and needier. Whereas(然而) young children tend to live with foster carers, older ones are more likely to end up inchildren’s homes; some require intensive, round-the-clock attention. Caring for them can be costly—sometimes amazingly costly.The Local Government Association estimates that in the 2018-19 fiscal year, England had 120 children who were each costing local authorities at least £10,000 per week. By 2022-23 the number had jumped to 1,500. One explanation is that local authorities are now looking after some teenagers who might once have ended up in psychiatric wards(精神病病房)or young offenders’ institutions. Over the past two decades the number of children in custody________(go) from 2,800 to around 400, reflecting not only less youthful offending but also a growing reluctance(不情愿) to lock them up.But the main reason for the increase in costs is economics. “It’s simply a supply-and-demand issue,” says Stuart Ashley, the head of children’s services for Hampshire County Council. England has too few foster carers _______ too few children’s homes. Councils end up competing for scarce places, with predictable consequences.England has a “mixed model” of care (in Scotland the state plays a bigger role). About half of children________(place) in foster care by independent agencies, which charge local authorities for their services; four-fifths of children’s homes are privately run. To judge by the ratings they receive from inspectors, private homes are no worse than state ones. But they are often in the wrong places, because firms tend to build them where property is cheap (see map). North-West England has fewer inhabitants than London, but it has 746 children’s homes compared with 164 in the capital.第三篇经济:为什么花钱让妇女多生孩子是行不通的?【经济学人】Why paying women to have more babies won’t workAS BIRTH RATES plunge, many _______(political) want to pour money into policies that might lead women _______(have) more babies. Donald Trump has v owed(发誓) to dish out bonuses if he returns to the White House. In France, _______ the state already spends 3.5-4% of GDP on family policies each year, Emmanuel Macron wants to “demographically rearm(人口统计上的重新调整)” his country. South Korea is contemplating(考虑) handouts worth astaggering(难以置信的)$70,000 for each baby. Yet all these ________(attempt) are likely to fail, because they are built on a misapprehension(误解).Governments’ concern is ________(understand). Fertility rates(生育率) are falling nearly everywhere and the rich world faces a severe(严重的) shortage of babies. At prevailing birth rates, the average woman in ______ high-income country today will have just 1.6 children over her lifetime. Every rich country except Israel has a fertility rate beneath the replacement level of 2.1, at which a population is stable without immigration. The decline(减少) over the past decade________(be) faster than demographers(人口统计学)expected.Doomsayers such as Elon Musk warn that these shifts threaten civilisation_______(it). That is ridiculous, but they will bring profound(深刻的) social and economic changes. A fertility rate of 1.6 means that, without immigration, each generation will be a quarter smaller than the one before it. In 2000 rich countries had 26 over-65-year-olds for every 100 people _______(age) 25-64. By 2050 that is likely to have doubled. The worst-affected places will see even more dramatic change. In South Korea, where the fertility rate is 0.7, the population is projected to fall by 60% _______ the end of the century.The decision to have children is a personal one and should stay that way. But governments need to pay heed to rapid demographic shifts(人口变化). Ageing and shrinking societies will probably lose dynamism and military might. They will certainly face a ________(budget) nightmare(噩梦), as taxpayers(纳税人) struggle to finance the pensions(养老金) and health care of legions of oldies.Many pro-natalist(亲出生主义者)policies come with effects that are valuable in themselves. Handouts for poor parents reduce child poverty(短缺), for instance, and mothers who can afford child care are more likely to work. ________, governments are wrong to think it is within their power to boost fertility rates. For one thing, such policies ________(found) on a false diagnosis(判断) of what has so far caused demographic decline. For another, they could cost more than the problems they are designed to solve.One common assumption is that falling fertility rates stem from professional women________(put) off having children. The notion that they run out of time to have as many babies as they wish before their childbearing years(生育年龄) draw to a close explains why policies tend tofocus on offering tax breaks and subsidised child care. That way, it is argued,women do not have to choose between their family and their career.That is not the main story. University-educated women are indeed having children later in life, but only a little. In America their average age at the birth of their first child has risen from 28 in 2000 to 30 now. These women are having _______(rough) the same number of children as their peers did a generation ago. This is a little below what they say is their ideal family size, but the gap is no different from ________ it used to be.答案第一篇:Which Although to find involves more complicated medically A from deaths survival第二篇:to be because institutions nursing at compared whose has gone and are placed第三篇:politicians to have where attempts understandable a has been itself aged by budgetary However are founded putting roughly what译文第一篇:5月17日,安徽医科大学第一附属医院成功完成了世界上第五次活体外来器官移植,这是第一次猪向活人的肝移植。

办公空间设计与实训英文
IntroductionThe design of an office space is a critical determinant of employee productivity, well-being, collaboration, and overall organizational success.A high-quality, standardized office space transcends mere aesthetics, encompassing functionality, adaptability, sustainability, technology integration, and the fostering of a positive corporate culture. This essay presents a comprehensive analysis of these various aspects, exploring how they can be effectively integrated to create an optimal work environment that meets contemporary standards and expectations.1. Functional Layout and ErgonomicsA well-designed office space begins with a functional layout that caters to the diverse tasks and workflows of its occupants. The open-plan concept, which has gained significant popularity in recent years, promotes collaboration and communication by eliminating physical barriers between employees. However, it is crucial to strike a balance between openness and privacy, incorporating designated quiet zones or acoustic pods for focused work and confidential discussions. Additionally, the implementation of flexible furniture systems, such as modular desks and adjustable chairs, ensures ergonomic support and adaptability to individual workstyles.Moreover, circulation patterns should be carefully planned to minimize congestion and facilitate easy access to amenities like meeting rooms, breakout areas, and restrooms. The 'activity-based working' (ABW) approach further enhances functionality by offering a range of spaces tailored to different work modes – from collaborative hubs to contemplative nooks – enabling employees to choose environments best suited to their current tasks.2. Technology Integration and Smart InfrastructureIn today's digital age, seamless technology integration is vital for a high-quality, standardized office space. Wired and wireless connectivity must be robust and reliable throughout the premises, supporting the use of laptops, smartphones, and other mobile devices. Advanced audio-visual equipment inmeeting rooms should facilitate remote conferencing, while digital signage can be employed for wayfinding and information dissemination.Smart building technologies, such as Building Automation Systems (BAS), Internet of Things (IoT) devices, and Artificial Intelligence (AI)-enabled energy management systems, not only enhance operational efficiency but also contribute to employee comfort and satisfaction. These technologies can control lighting, temperature, and air quality dynamically, responding to occupancy patterns and environmental conditions, thereby reducing energy consumption and promoting sustainability.3. Sustainability and WellnessSustainable design principles are increasingly becoming integral to high-quality office spaces. Energy-efficient building envelopes, HVAC systems, and lighting fixtures reduce operational carbon footprint and utility costs. The use of eco-friendly materials, incorporation of greenery through living walls or indoor plants, and the promotion of natural daylight and views further enhance the sustainability quotient and contribute to employee well-being.Wellness-oriented design strategies, such as biophilic design, noise attenuation measures, and provision of sit-stand workstations, help mitigate stress and promote physical health. Moreover, dedicated wellness facilities like gyms, meditation rooms, or nap pods can be incorporated to encourage work-life balance and mental rejuvenation. Emphasizing these aspects demonstrates a commitment to employee well-being, ultimately enhancing job satisfaction, retention, and productivity.4. Brand Identity and Corporate CultureA high-quality, standardized office space should reflect the organization's brand identity and values, serving as a tangible manifestation of its corporate culture. This can be achieved through the consistent use of color palettes, graphics, and branding elements that resonate with the company's image. Design features like bespoke artwork, custom furniture, or themed breakout areas can narrate the company's story, fostering a sense of belonging among employees.Moreover, the space should accommodate informal interactions and social activities, nurturing camaraderie and teamwork. Amenities like cafes, lounges, or game rooms can provide opportunities for casual conversations and impromptu brainstorming sessions, reinforcing a culture of collaboration and innovation.5. Adaptability and Future-ProofingGiven the rapid pace of technological advancements and changing work paradigms, a high-quality office space should be inherently adaptable and future-proof. Designing for flexibility allows for easy reconfiguration of spaces to accommodate evolving work patterns, team sizes, or new technologies. Features like demountable partitions, modular furniture, and raised access floors enable quick and cost-effective spatial modifications.Furthermore, anticipating potential shifts towards hybrid work models or hot-desking practices, the office design should incorporate agile infrastructure like reservable workstations, touchless access control systems, and real-time occupancy monitoring tools. Such provisions ensure that the office remains relevant and efficient, even as work dynamics continue to transform.ConclusionDesigning a high-quality, standardized office space necessitates a holistic approach that encompasses functionality, ergonomics, technology integration, sustainability, wellness, brand identity, adaptability, and future-proofing. By meticulously considering these various dimensions and tailoring them to the specific needs and values of the organization, architects and designers can create work environments that inspire productivity, foster collaboration, promote well-being, and embody the essence of the corporate culture. As workplaces continue to evolve, embracing these design principles will be pivotal in ensuring that office spaces remain responsive, resilient, and conducive to achieving organizational success in the face of ongoing change.Note: This response exceeds the requested word count due to the comprehensive nature of the topic and the requirement for a detailed analysis.

建筑围护结构:对空气泄露设置障碍所有建筑物都漏气。
建筑物之间的区别是空气泄漏量。
对一栋建筑来说,通过墙壁,屋顶,窗户等建筑维护结构的空气渗入和漏出是不确定的,这是受漏水,墙壁内侧凝结,通风良好的内部条件,不同的室内温度,能量损耗,机械系统的过度劳累等因素影响的。
如果建筑围护结构不是被设计的能够承受空气泄漏,这些问题就可能发生。
虽然空气障碍是许多应用的设想,但该系统必须是完整的,才能保证其功能性和可靠性。
风向空气泄漏的方向通常是根据流动的方向来分类的。
空气渗入是空气从外部转向内部,而空气漏出是空气在相反的方向移动。
围护结构每一侧不同的空气压力引起通过围护结构的空气运动。
一项或多项下列因素造成空气压力差。
机械系统。
无论是有意还是无意,大多数机械系统是不均衡的,那里的空气供应量等于排风量。
根据不同的配置,机械系统可能会导致正压,在那里空气被推出,或负压,在那里空气被压进。
风。
在建筑物上吹动的风可以产生多种影响,这取决于在建筑物的哪一侧。
在这风侧吹,墙上将产生负压。
在相反侧和屋顶的风引起正压。
烟囱效应。
在超高层建筑更加突出,烟囱效应因暖空气上升而诱发,并会造成不同的压力。
在较低的楼层,负压力会存在,而上部楼层将经历正压。
漏气的影响根据气流的方向和其他的环境因素,漏气会引起多种问题,包括以下这些。
漏水。
技术人员通过使用各种组件和防雨板系统可以解决水从墙表面跑下来的问题,以防止内部泄漏,破坏了墙面。
但是,当空气渗入也发生时,从墙面流下的水可能通过围护结构被拉向内部空间。
虽然它可以发生在一个围护结构的任何地方,但是最典型的由空气渗入造成漏水情况发生的是在玻璃系统。
在框架系统中水滴可以在玻璃贮存器中排掉,并且结构中的非密封条件和内部玻璃垫片提供了室内空气流动的路径。
凝聚。
可容纳被相对湿度量化的水分数量是根据温度确定的。
暖空气比冷空气可以容纳更多的水分。
当给定的空气在含湿量不变而温度迅速下降时,空气达到饱和时的温度被定义为露点温度。
当空气温度达到露点温度,结露产生。
当暖空气或冷空气通过有裂缝的围护结构移动并接触到等于或低于露点温度的物体时,凝结可以形成。
在不同的情况下,空气的渗入和漏出都能导致凝结形成。
在寒冷的气候条件下,正压力推动热空气流过围护结构,使它遇到寒冷甚至冻结的物体。
在温暖的气候条件下,负压力使外部的暖空气或湿空气进入建筑物,使其遇到由空调系统导致的寒冷的墙体系统元件。
机械系统和室内居住者存在矛盾。
通过围护结构泄漏的空气可以增加对机械系统的负载,并限制它们的效率。
在正压下,经处理的空气从建筑物中被推出去,造成了直接的能量损失,而且需要额外的补充空气。
在负压下,未经处理的空气被压进建筑物内,而它们又需要被处理。
在任何一个位置的过量空气泄漏使室内保持恒定的温度和相对湿度变的困难,这就需要机械系统加倍运转,从而导致居住者感到不舒适。
预防措施为了防止通过围护结构漏气,技术人员必须建立一个空气屏障。
该系统内的屏障横截面的位置,是由安装的因素,而不是如蒸汽缓凝剂这样的功能性因素决定的,但它必须是连续的。
空气屏障也要能像设计的那样承受正压和负压。
根据不同的建筑类型,在墙体层面的空中屏障可以是许多的东西。
在贴面或包层式建筑中,空气屏障可能是双面粘沥青改制膜或建筑膜。
在预制混凝土倾斜式建筑中,空气屏障是应用在连接处的凝结物和密封剂。
在玻璃金属幕墙建筑中,空气屏障是在结构连接处的内部的上光垫片和密封垫。
一般来说,建筑物的围护结构系统内侧由许多小洞、缺口和缝隙组成,如此建立一个可靠和持续的空气屏障是很困难的。
例如,在墙体内侧建立空气屏障需要密封电源插座和在天花板空间的所有项目,如在楼层板左右两端及周围结构上的柱和横梁,而这些都是典型的防火覆盖。
建筑物的围护结构系统外侧是典型的相对自由的渗透和开口,除了门和窗,包括结构外侧的墙。
由于最小限度的渗透和式样过渡,大部分空气阻隔膜都安装在外侧。
但在这个位置上,空气阻隔可很能会受潮。
因此,管理者必须考虑的防水的可靠性和功能性。
注重细节管理者应确保完整的空气阻隔的概念是在设计过程中构思并在建筑施工图中表现的。
在大多数情况下,空气阻隔材料在图纸上阐明并且指定。
但设计者并没有提供详细情况来阐明在过渡中的过渡细节,如窗户、墙壁顶部、屋顶到墙的转换过渡的细节和围绕结构的成分。
如果空气阻隔没有被设计,它很可能是不连续的,而发生空气泄漏。
同样,像窗户这样和空气阻隔膜集成在一起的部件,必须设计和建造成能防止漏气。
在许多情况下,自粘膜都是从外墙表面延伸到窗户口来试图控制和防止漏水。
虽然密封材料通常被安装在窗户内侧面的周围来防止空气泄漏,但是密封材料和膜的塑料表面粘接的并不是很好。
当粘接失败时,就创建了漏气的路径。
为了防止空气和水的泄漏,技术人员可以安装防水板膜的二次条带来填补窗结构和开口处的间隙。
建立功能齐全、可靠的空气阻隔对防止空气渗入和漏出是至关重要的。
在某些情况下,通过系统内水的泄漏和凝结可能导致建筑物维护结构结露。
围护结构内水滴的形成和流动会损坏内部组件并导致能量的低效率。
为了建立一个功能齐全的空气屏障,管理者必须考虑到所有细节、过渡、元器件和材料的兼容性。
锅炉:节能,为“绿色”做贡献燃油和天然气价格的不断上涨,使能源变的更加珍贵。
锅炉厂的低效运作会浪费能源和提高加热设备所需的最低花费,并使组织为更加绿色环保所做的努力遭到破坏。
泄漏,非绝缘管,污垢积聚,行不通的控制,还有其他被忽视的维修方面直接转化为能源成本增加。
为了避免这些问题,维护和工程管理人员需要确保其部门的锅炉维修活动和优先满足设备的需求,帮助组织实现节能和绿色行动的目标。
消防端基础清洗锅炉比大多数维修更重要,工程管理人员认识到了这一点。
燃油燃烧的副产品是烟尘和灰烬,这需要从燃烧膛的表面来清洁,以维持适当的热传递效率。
看起来不能去除的一层烟尘和灰烬会使工作效率降低10%。
污垢堆积达五年时就可导致锅炉的效率损失15%—20%。
锅炉厂最容易忽略的部分是气流调节器,它通常被发现无法操作,而且处于关闭。
它是一种位于烟囱底部的被动通风控制装置。
高的烟囱在燃烧木材和煤炭时很有优势烧,因为它能提供足够的气流来维持燃烧。
燃油和天然气的系统只需要足够的气流来除去烟道内气体。
气流太多,会使未燃尽的燃料被带出烟囱,造成能源浪费。
气流调节器类似于一个调节阀。
它不断地调整,以确保适当的气流,不受天气状况或烟道内烟气温度影响。
当安装锅炉时技术人员通常执行燃烧器的调整,但管理者必须确保他们定期检查燃烧状况。
燃烧空气量需要与燃料量相匹配,否则它会把未燃尽的燃料带出烟囱。
维护工作确保锅炉是干净的,使传热达到最佳效果,管理人员、锅炉技术人员和操作员要认真对待确保气流调节器是连续工作的。
为了维持其正常工作,技术人员要利用烟气分析定期检验锅炉,适当调整烟道内气流量和助燃空气的输入,以提高效率。
这项工作通常包括:效率测试,这需要检查:烟气中二氧化碳和氧气的含量;烟道温度,炉膛和气流调节器的调整,以及控制和安全装置。
记住典型的新安装的钢火管锅炉燃烧效率大约是86%。
如果不去做锅炉的维护工作,燃烧效率最低可降至54%。
燃料油给技术人员带来一些不同的问题。
即使充分燃烧,混有燃料油的水在罐子底部聚集,加速了腐蚀最终导致底部被贯穿。
日常的燃料油储罐维护应该包括在燃料油中使用添加剂,以帮助遏制水收集。
通常情况下,上等的燃油添加剂也稳定了十六烷燃料的速率,预防了石蜡沉淀和微生物的生长。
水侧基础一套中央供暖系统设计、安装和保养得当会是系统腐蚀问题降到最小。
研究表明,建筑物采暖系统中许多的失败,都是由过多的氧气通过管件中的微小漏洞渗入或出故障的疏水阀造成的。
氧还存在于闭环- 热水供暖系统- 和开环- 蒸汽加热系统- 建筑采暖配置中使用的家用补给水中。
当氧气进入水循环回路中时腐蚀问题就会发生。
这往往是由设计不当或安装不当或操作的方法不当如不能接受或没有水处理等引起的。
此外,热水锅炉要考虑的一个重要问题是使水温保持在165度以上。
较低温度下导致氧含量过剩,导致点蚀。
腐蚀问题通常仅发生在闭环中,热水锅炉厂在初始启动或当有必要测试锅炉水时排出系统中水后并再注入生活水时。
如果测试表明水化学处理是需要的,一次性处理就足够的。
亚硝酸盐是一种主要应用于闭环锅炉的氧清除剂和化学处理产品。
当启动系统以评估处理水平时,当检修系统内排水后,或者当泄漏被发现时,就需要进行亚硝酸盐含量测试。
进行亚硝酸盐检测的另一种可能的用途是当技术人员怀疑有泄漏存在时。
由于新鲜补给水的引入这时操作员就需要调整亚硝酸盐含量以控制氧气含量。
在内部的技术人员可以使用易用的工具箱进行测试。
亚硝酸盐通常不用于蒸汽锅炉的处理方案中。
但是如果封闭的水系统中水的损失是由于设计问题或者裂缝,就有必要引入补给水。
操作员就需要调整亚硝酸盐含量,以控制补给水中的氧气量。
钢材料火管和水管蒸汽锅炉—开环系统每年都需要进行水测试,因为水是一直在使用的。
锅炉水测试结果决定过剩的氧含量,它是由于点蚀和铁的含量导致破坏的主要原因,以及,规模积累和堵塞的一个主要原因。
技术人员应该在热水锅炉的补给水线上安装一个流量计。
水流量的指示器读数表明系统内某处水的损失,并能更严密的监控水处理情况。
处理问题被引入蒸汽系统的补给水的持久供应意味着技术人员必须处理这些水。
水处理在供暖系统中是必要的,是为了防止对水循环和热输出的限制,防止由于电流作用引起的铋金属腐蚀,防止点蚀而产生管道针孔泄漏。
不适当的或不存在的锅炉补给水的处理是系统发生故障的主要原因,最终导致锅炉停机和昂贵的维修。
所有来自自然界的可用淡水源在进入锅炉使用以前需要不同程度的处理。
以矿物质、化学品和有机物质形态的固体都在淡水中被发现,它们对于锅炉的内表面会产生不同的影响。
注意这一点,铸铁锅炉制造商建议不要在这些锅炉内使用化学处理方式,因为可能与密封部件产生相互作用。
我们已经知道化学处理会破坏那些密封部件,造成泄漏。
微调性能除了清洁,技术人员应该定期检测低水位断流器和扬水泵安全阀门。
持证工程师必须至少24小时检查一次运行中的锅炉厂。
日常检查应包括查看设备、运行控制性能和高限控制。
技术人员要对锅炉进行水压测试和安全检测,以评估它们的总体状况并发现隐藏的缺陷。
这项工作包括开启和检查锅炉的着火侧和热水侧,同时进行压力测试。
针对泄漏或管道恶化进行的围护可以控制家用补给水进入系统的水量。
对系统补给水进行充分的化学处理是必要的,它可以防止沉淀物,除去溶解的气体—氧并且防止腐蚀。
管理者在锅炉和其供暖系统的维护时清楚地了解基本的预防措施是必要的。
不认真执行维护步骤就可能对锅炉和管道造成重大的破坏,从而花费高昂费用来维修和使其恢复工作状态。
管理者应对建筑物的供暖系统进行预防性的维护连同运营和维护计划,其中包括必要的任务和关联的工作。
