Text 1

Nearly 2000 years ago, as the Romans began to pull out of Scotland, they left behind a curious treasure:10 tons of nails, nearly a million of the things. The nail hoard was discovered in 1960 in a four-metre-deep pit covered by two metres of gravel.Why had the Romans buried a million nails? The likely explanation is that the withdrawal was rushed, and they didn’t want the local Caledonians getting their hands on 10 tons of weapon-grade iron. The Romans buried the nails so deep that they would not be discovered for almost two millennia.Later civilisations would value the skilled blacksmith’s labour in a nail even more than the raw material. As Roma Agrawal explains in her new delightful book Nuts and Bolts, early 17th-century Virginians would sometimes burn down their homes if they were planning to relocate. This was an attempt to recover the valuable nails, which could be reused after sifting the ashes. The idea that one might burn down an entire house just to reclaim the nails underlines how scarce, costly and valuable the simple-seeming technology was.The price of nails fell by 90% between the late 1700s and mid-1900s, as economist Daniel Sichel points out in a research paper. According to Sichel, although the falling price of nails was driven partly by cheaper iron and cheaper energy, most of the credit goes to nail manufactures who simply found more efficient ways to turn steel into nails.Nails themselves have changed over the years, but Sichel studied them because they haven’t changed much. Roman lamps and Roman chariots are very different from LED strips and sports cars, but Roman nails are still clearly nails. It would be absurd to try to track the changing price of sports cars since 1695, but to ask the same question of nails makes perfect sense.I make no apology for being obsessed by a particular feature of these objects: their price. I am an economist, after all. After writing two books about the history of inventions, one thing I’ve learnt is that while it is the enchantingly sophisticated technologies that get all the hype, it’s the cheap technologies that change the world.The Gutenberg printing press transformed civilisation not by changing the nature of writing but by changing its cost-and it would have achieved little without a parallel collapse in the price of surfaces to write on, thanks to an often-overlooked technology called paper. Solar panels had few niche uses until they became cheap; now they are transforming the global energy system.

Parenting tips obtained from hunter-gatherers in Africa may be the key to bringing up more contented children, researchers have suggested. The idea is based on studies of communities such as the Kung of Botswana, where each child is cared for by many adults. Kung children as young as four will help to look after younger ones and “baby-wearing”, in which infants are carried in slings, is considered the norm.

According to Dr Nikhil Chaudhary, an evolutionary anthropologist at Cambridge University, these practices, Known as alloparenting, could lead to less anxiety for children and parents.

Dr Annie Swanepoel, a child psychiatrist, believes that there are ways to incorporate them into western life. In Germany, one scheme has paired an old people’s home with a nursery. The residents help to look after the children, an arrangement akin to alloparenting. Another measure could be encouraging friendships between children indifferent school years to mirror the unsupervised mixed-age playgroups in hunter-gatherer communities.In a paper published in the Journal of Child Psychology and Psychiatry, researchers said that the western nuclear family was a recent invention which family broke with evolutionary history. This abrupt shift to an “intensive mothering narrative”, which suggests that mothers should manage childcare alone, was likely to have been harmful. “Such narratives can lead to maternal exhaustion and have dangerous consequences,” they wrote.By contrast, in hunter-gatherer societies adults other than the parents can provide almost half of a child’s care. One previous study looked at the Efe people of the Democratic Republic of Congo. It found that infants had an average of 14 alloparents a day by the time they were 18 weeks old and were passed between caregivers eight times an hour.Chaudhary said that parents now had less childcare support from family and social networks than during most of humans’ evolutionary history, but introducing additional caregivers could reduce stress and maternal depression, which could have a “knock-on” benefit to a child’s wellbeing. An infant born to a hunter-gatherer society could have more than ten caregivers — this contrasts starkly to nursery settings in the UK where regulations call for a ratio of one carer to four children aged two to three.While hunter-gatherer children learnt from observation and imitation in mixed-age playgroups, researchers said that western “instructive teaching”, where pupils are asked to sit still, may contribute to conditions such as attention deficit hyperactivity disorder. Chaudhary said that Britain should explore the possibility that older siblings helping their parents “might also enhance their own social development.”

26. According to the first two paragraph, alloparenting refers to the practice of _________.

A. sharing child care among community members

B. assigning babies to specific adult caregivers

C. teaching parenting details to older children

学习啦在线学习网D. carrying infants around by their parent

27. The scheme in Germany is mentioned to illustrate _________.

学习啦在线学习网A. an attempt to facilitate intergenerational communication

学习啦在线学习网B. an approach to integrating alloparenting into western culture

学习啦在线学习网C. the conventional parenting style in western culture

学习啦在线学习网D. the differences between western African ways of living

28. According to Paragraph 4, the “intensive mothering narrative” _________.

学习啦在线学习网A. alleviate parenting pressure

学习啦在线学习网B. considerate family relationships

C. results in the child-centered family

D. departs from the course of evolution

学习啦在线学习网29. According to paragraph 6, what can we learn about nursery in the UK?

A. They tend to fall short of official requirements.

学习啦在线学习网B. They have difficulty finding enough caregivers.

C. They ought to improve their carer-to-child ratio.

D. They should try to prevent parental depression.

学习啦在线学习网30. Which of the following would be the best title?

B. For a happier family, learn from the hunter-gatherers.

C. Mix-aged playgroup, a better choice for lonely children.

Text 3

Rutkowski is a Polish digital artist who uses classical painting styles to create dreamy fantasy landscapes. He has made illustrations for games such as Sony’s Horizon Forbidden West, Ubisoft’s Anno, Dungeons & Dragons, and Magic: The Gathering. And he’s become a sudden hit in the new world of text-to-image AI generation.His distinctive style is now one of the most commonly used prompts in the new open-source AI art generator Stable Diffusion, which was launched late last month. The tool, along with other popular image-generation AI models, allows anyone to create impressive images based on text prompts. For example, type in “Wizard with sword and a glowing orb of magic fire fights a fierce dragon Greg Rutkowski,” and the system will produce something that looks not a million miles away from works in Rutkowski’s style.But these open-source programs are built by scraping images from the Internet, often without permission and proper attribution to artists. As a result, they are raising tricky questions about ethics and copyright. And artists like Rutkowski have had enough.According to the website Lexica, which tracks over 10 million images and prompts generated by Stable Diffusion, Rutkowski’s name has been used as a prompt around 93,000 times. Some of the world’s most famous artists, such as Michelangelo, Pablo Picasso, and Leonardo da Vinci, brought up around 2,000 prompts each or less. Rutkowski’s name also features as a prompt thousands of times in the Discord of another text-to-image generator, Midjourney. Rutkowski was initially surprised but thought it might be a good way to reach new audiences. Then he tried searching for his name to see if a piece he had worked on had been published. The online search brought back work that had his name attached to it but wasn’t his.“It’s been just a month. What about in a year? I probably won’t be able to find my work out there because [the internet] will be flooded with AI art,” Rutkowski says. “That’s concerning.”“There is a coalition growing within artist industries to figure out how to tackle or mitigate this,” says Ortiz. The group is in its early days of mobilization, which could involve pushing for new policies or regulation. One suggestion is that AI models could be trained on images in the public domain, and AI companies could forge partnerships with museums and artists, Ortiz says.

31. What can be learned about Rutkowski from the first two paragraphs?

学习啦在线学习网A. He is enthusiastic about AI generation painting.

B. He is popular with the users of an AI art generator.

C. He attracts admiration from other illustrators.

学习啦在线学习网D. He specializes in classical painting digitalization.

学习啦在线学习网32. The problem with open-source AI art generators is that they _________.

A. lack flexibility in responding to prompts

学习啦在线学习网B. produce artworks in unpredictable styles

C. make unauthorized use of online images

D. collect user information without consent

33. After searching online, Rutkowski found _________.

学习啦在线学习网A. a unique way to reach audiences

学习啦在线学习网B. a new method to identify AI images

C. AI-generated work bearing his name

D. heated disputes regarding his copyright

学习啦在线学习网34. According to Ortiz, AI companies are advised to _________.

A. campaign for new policies or regulations

B. offer their services to public institutions

C. strengthen their relationships with AI users

D. adopt a different strategy for AI model training

35. What is the text mainly about?

学习啦在线学习网A. Artists’ responses to Al art generation.

学习啦在线学习网B. AI’s expanded role in artistic creation.

学习啦在线学习网C. Privacy issues in the application of Al.

D. Opposing views on AI development.

Text 4

The miracle of the Chesapeake Bay lies not in its depths, but in the complexity of its natural construction, the interaction of fresh and saline water and the mix of land and water. The shallows provide homes for hundreds of species while storing floodwaters, filtering pollutants from water, and protecting nearby communities from potentially destructive storm surges.All this was put at great risk late last month, when the US Supreme Court issued a ruling in an Idaho case that provides the EPA far less authority to regulate wetlands and waterways. Specifically, a 5-4 majority decided that wetlands protected by the EPA under it Clean Water Act authority must have a “continuous surface connection” to bodies of water. This narrowing of the regulatory scope was a victory for builders, mining operators and other commercial interests often at odds with environmental rules. And it carries “significant repercussions for water quality and flood control throughout the US,” as Justice Brett Kavanaugh observed.

学习啦在线学习网In Maryland, the good news is that there are many state laws in place that provide wetlands protections. But that’s a very shortsighted view, particularly when it comes to the Chesapeake Bay. The reality is that water and the pollutants that so often come with it, don’t respect state boundaries. The Chesapeake draws from a 64000-square-mile watershed that extends to Virginia, Pennsylvania, New York, West Virginia, the District of Columbia and Delaware. Will those jurisdictions extend the same protections now denied under Sackett V. EPA? Perhaps some, but all? That seems unlikely.

学习啦在线学习网It is too easy, and misleading, to see such court rulings as merely standing up for the rights of land owners when the consequences can be so dire for their neighbors. And it’s reminder that they EPA’s involvement in the Chesapeake Bay program has long been crucial as the means to transcend the influence of deep-pocketed special interests in neighboring states. Pennsylvania farmers, to use one telling example, aren’t thinking about next year’s blue crab harvest in Maryland when they decide whether to spread animal waste on their fields, yet the runoff into nearby creeks can have enormous impacts downstream.And so we would also call on state lawmakers from Richmond to Albany to consider reviewing their own wetlands protections and see for themselves the enormous stakes involved. We can’t offer them a trip to the Chesapeake Bay model. It’s been gone since the 1980s but perhaps a visit to Blackwater National Wildlife Refuge in Dorchester County where American bald eagles fly over tidal marshes so shallow you could not paddle a boat across them but teaming with aquatic life. It’s worth the scenic drive.

学习啦在线学习网36. The Chesapeake Bay is described in Paragraph 1 as _________.

A. a valuable natural environment

B. a controversial conservation area

学习啦在线学习网C. a place with commercial potential

D. a headache for nearby communities

学习啦在线学习网37. The U.S. Supreme Court’s ruling in the Idaho case _________.

学习啦在线学习网A. reinforces water pollution control

学习啦在线学习网B. weakens the EPA’s regulatory power

学习啦在线学习网C. will end conflicts among local residents

学习啦在线学习网D. may face opposition from mining operators

38. How does the author feel about the future of the Chesapeake Bay?

A. Worried.

学习啦在线学习网B. Puzzled.

C. Relieved.

学习啦在线学习网D. Encouraged.

学习啦在线学习网39. What can be inferred about the EPA’s involvement in the Chesapeake Bay Program?

A. It has restored the balance among neighboring jurisdictions.

学习啦在线学习网B. It has triggered a radical reform in commercial fisheries.

C. It has set a fine example of respecting state authorities.

D. It has ensured the coordination of protection efforts.

40. The author holds that the state lawmakers should _________.

学习啦在线学习网A. be cautious about the influence of landowners

学习啦在线学习网B. attach due importance to wetlands protections

学习啦在线学习网C. recognize the need to expand wildlife refuges

学习啦在线学习网(41) HannahSimply, there are people in Nigeria who cannot travel to the Smithsonian Institution to see that part of their history and culture represented by the Benin Bronzes. These should be available to them as part of their cultural heritage and history and as a source of national pride. There is no good reason that these artifacts should be beyond the ordinary reach of the educational objectives or inspiration of the generations to which they were left. They serve no purpose in a museum in the United States or elsewhere except as curious objects. They cannot be compared to works of art produced for sale which can be passed from hand to hand and place to place by purchase.(42) BuckWe know very exact reproductions of artwork can be and are regularly produced. Perhaps museums and governments might explore some role for the use of nearly exact reproductions as a means of resolving issues relating to returning works of art and antiquities. The context of any exhibit is more important to me than whether the object being displayed is 2,000 years old or 2 months old. In many cases the experts have a hard time agreeing on what is the real object and what is a forgery. Again, the story an exhibit is trying to tell is what matters. The monetary value of the objects on display is a distant second place in importance.(43) SaraWhen visiting the Baltimore Museum of Art, I came across a magnificent 15th-century Chinese sculpture. It inspired me to learn more about the culture that it represented. Artifacts in museums have the power to inspire, and perhaps spark that need to learn and understand the nature of their creators. Having said that, I do feel that whatever artifacts find their way to public museums should, in fact, be sanctioned as having been obtained on loan, legally purchased, or obtained by treaty. Stealing artifacts from other peoples’ cultures is obscene; it robs not only the physical objects, but the dignity and spirit of their creators.(44) VictorAncient art that is displayed in foreign countries by all means should be returned to the original country. The foreign countries have no right to hold back returning the items. I would ask that the foreign nations and the original country discuss the terms of transfer. Yes, there is the risk that the original country will not have as good security as do the foreign countries.But look at what happened to Boston’s Gardner Museum theft in 1990, including the loss of Rembrandt, Vermeer, Manet, and other masterpieces. Nothing is absolutely safe nowhere. And now Climate Change agitators are attacking publicly displayed works in European museums.(45) JuliaTo those of you in the comments section who are having strong feelings about Artifacts being removed from cities in the US and Britain and returned to their Countries of origin, I would ask you to consider why do you think Americans have more of a right to easily access the Benin Bronzes than the people of Nigeria? Why are people who live within a day’s drive of London entitled to go and see the Elgin Marbles whenever they want, but the people of Athens aren’t? What Intrinsic factors make the West a suitable home for these artifacts but preclude them from being preserved and displayed by their countries of origin?If your conclusion is that the West is better able to preserve these artifacts,think about Why you’re assuming that to be true.A. It is clear that countries of origin have never been compensated for stolen artifacts.B. It is a flawed line of reasoning to argue against returning artifacts to their countries of origin.C. Museum visitor can still learn as much from artifacts copies after the originals are returned.D. Reproductions, even if perfectly made, cannot take the place of the authentic objects.E. The real value of artifacts can only be recognized in their countries of origin rather than anywhere else.F. Ways to get artifacts from other countries must be decent and lawful.G. Concern over security is no excuse for refusing to return artifacts to their countries of origin.

“Elephants never forget” — or so they say — and that piece of folklore seems to have some foundation.The African savanna elephant also known as the African bush elephant, is distributed across 37 African countries. (46)They sometimes travel more than sixty miles to find food or water, and are very good at working out where other elephants are—even when they are out of sight. Using tracking devices, researchers have shown that they have “remarkable spatial acuity”, when finding their way to waterholes, they headed off in exactly the right direction, on one occasion from a distance of roughly thirty miles. What is more, they almost always seem to choose the nearest water hole. (47)The researchers are convinced that the elephants always know precisely where they are in relation to all the resources they need, and can therefore take shortcuts, as well as following familiar routes.Although the cues used by African elephants for long-distance navigation are not yet understood, smell may well play a part.Elephants are very choosy eaters, but until recently little was known about how they selected their food. (48)One possibility was that they merely used their eyes and tried out the plants they found, but that would probably result in a lot of wasted time and energy, not least because their eyesight is actually not very good.(49)The volatile chemicals produced by plants can be carried a long way, and they are very characteristic: Each plant or tree has its own particular odor signature. What is more, they can be detected even when they are not actually visible. New research suggests that smell is a crucial factor in guiding elephants — and probably other herbivores — to the best food resources.The researchers first established what kinds of plant the elephants preferred either to eat or avoid when foraging freely. They then set up a “food station” experiment, in which they gave elephants a series of choices based only on smell. (50) The experiment showed that elephants may well use smell to identify patches of trees that are good to eat, and secondly to assess the quality of the trees within each patch. Free-ranging elephants presumably also use this information to locate their preferred food.

考研英语一难不难

考研英语比6级难度大。

学习啦在线学习网六级英语的考试主要是对学生使用能力的测评，范围确实由易到难的六级以内的水平。

考研英语，是一场残酷的选拔赛，通过每年的考研人数及通过率指导这是一个淘汰型极强的考试方式。而英语难度也随之上升，为了形成“两极分化明显“的目的。

考研英语一和英语二的区别有哪些

1、难度：总的来说，考研英语一比考研英语二稍微难一点，毕竟专业型硕士对英语的要求和理解稍微低些，但是其实这个影响并不大，因为大多数人都是考英语一，难度高的同时大家难度都高

学习啦在线学习网2、词汇量：英语二大纲要求的阅读理解单词量与英语一相同，但在大纲中英语二阅读理解没有说明有超纲单词，而英语一明确说将有百分之三的超纲单词。

学习啦在线学习网3、完形填空：英语一的文章相对较短，长度为240-280个单词;英语二的文章长度大约为350个单词。

4、阅读理解：英语二的文章比英语一的稍微简单点，主要是选项要比英语一的简单一些，英语一四篇文章长度大约为1600个单词，英语二则稍短大约为1500个单词。

5、新题型：英语二和英语一不太一样，英语一主要是七选五，选小标题和排序，英语二是选小标题，正误判断和多项对应，感觉这个英语二的这个比较简单，是得分的重点。新题型主要有三类，一类是打乱文章排序列，一类是选段或句补充到文章里，还有一类是选标题。

6、翻译：这也是一大不同，英语一是从一篇约400词的文章中选出五句话来分别翻译，英语二是全篇翻译，虽然是全篇，但这比较简单，长度为150词左右，是得分的重点 。

7、两篇作文：英语一和二题型基本一样，都是分为小作文和大作文，英语一小作文是以应用文为主，一般都是写信，英语二除了应用文(主要写信)以外，还有一个新的，就是摘要，二者要求都是100字左右;大作文的话，英语一大多数都是以看图(动漫)说话并评论为主，字数要求是160——200单词，英语二也是看图，但是以看图表为主，字数为150字以上。
