For many older Chinese the milky flavour recalls a Communist-era childhood when few other treats were available.【2】The sweets predate the Communist Party takeover in 1949. This year theyturn 80. As one of the few pre-Communist products still thriving, they have a thing or two to teach China’s new tech upstarts about longevity.【3】The rabbit has reinvented itself many times, most recently in November whenit teamed up with Coach, a high-end American fashion firm, toproduce giant bunnies on handbags (pictured) costing up to 7,500 yuan ($1,050), as well as flouncy dresses, denim jackets and a gold White-Rabbit necklace (hopped up at 9,500 yuan). Tapping into nostalgia in the Chinese market, the collaboration gives Coach a boost in the complex warren of Chinese consumerism,while enabling White Rabbits to breed new followers across the Pacific.【4】China’s first domestic toffees were produced in 1943 with Mickey Mouse on the wrapper. When such Americana fell out of favour in the 1950s,the rodent was replaced by da baitu, a big white rabbit, which gave the brand its name. The stylised blue-and-white cartoon bunny became an icon: in 1972 Zhou Enlai, then China’s prime minister, presented White Rabbits to Richard Nixon on his first visit to Communist China. Soviet leaders visiting Beijing also enjoyed such gifts.【5】The fortunes of the sweet soured after Mao Zedong died in 1976. As foreign goods poured in, White Rabbits lost their domestic dominance. Guan Sheng Yuan, the state-owned company that makes them, touted thetreat’s nutritional properties—seven sweets were equivalent to drinking a glass of milk, according to a popular slogan—but parents became harder to lure with such claims.【6】The confectionery even fell foul of China’s food-safety scandals in 2008 when thousands of children became ill drinking Chinese powderedmilk contaminated with melamine, and dairy products were removed from shops at home and abroad. White Rabbits are now made using imported milk powder.【7】The bunnies fought back. In 2018 the first batches of White Rabbit lip balm sold out within hours. The following year the manufacturer teamed up with Godiva, a chocolate company, to make White Rabbit ice cream and people queued for hours to buy the newly launched White Rabbit milk tea at a pop-up shop in Shanghai. The company has since launched perfumes, a shower gel and hand cream. In 2021 Guan Sheng Yuan opened a shop in Shanghai selling all manner of branded products. 【8】The sweet-maker has capitalised on the trend for guochao, a phrase meaning “national wave”, applied to trendy Chinese-made consumer goods that appeal tothe nostalgia and patriotism of the young. Liushen, a traditional mosquito repellent, collaborated with KFC to make a refreshing herbal drink for the summer. The Forbidden City in Beijing even produced a range of lipsticks named for the colours of ancient artefacts.【9】White Rabbit’s collaboration with luxury brands received a boost this year from the arrival of the year of the rabbit in the Chinese zodiac. Sales in the first quarter were up by 10% year on year, according to Guan Sheng Yuan. To see in the new year, SK-II, a Japanese skincare brand, launched a limited-edition White Rabbit face serum(the bottles warned consumers: “Do not eat”). Foreign markets provide an additional carrot. The candies have diversified into a whole rangeof flavours, such as peanut, red-bean, mustard and durian, and are exported to more than 50countries. That’s a whole different rabbit-hole.长难句:1.原文:The rabbit has reinvented itself many times, most recently in November when it teamed up with Coach, a high-end American fashion firm, to produce giant bunnies on handbags (pictured) costing up to 7,500 yuan ($1,050),as well as flouncy dresses, denim jackets and a gold White-Rabbit necklace (hopped up at 9,500 yuan).2.分析:主句是主谓宾结构The rabbit(主语)has reinvented(谓语动词)itself(宾语)。

经济学人原文Clause for thought: first non-invasive way to read minds as AI turns brain activity into text【1】An AI-based decoder that can translate brain activity into a stream of text has been developed, in a breakthrough that allows thoughts to be read non-invasively for the first time. The decoder could reconstruct speech with uncanny accuracy while people listened to a story – or even silently imagined one – using only fMRI scan data. Previous language decoding systems have required surgical implants, and the latest advance raises the prospect of new ways to restore speech in patients strugglingto communicate as a result of stroke or motor neurone disease. Dr Alexander Huth, a neuroscientist who led the work at the University of Texas at Austin, said: “We were kind of shocked that it works as well as it does. I’ve been working on thisfor 15years … so it was shocking and exciting when it finally did work.”【2】Mind-reading has traditionally been the preserve of sci-fi, in characters such as the X-Men’s Jean Grey, but the latest AI technology has finally taken the concept into the real world. This decoder’s achievement overcomesa fundamental limitation of fMRI: while the technique can map brain activity toa specific location with incredibly high resolution, there is an inherent time lag, which makes tracking activity in real time impossible. The lag exists because fMRI scans measure the blood-flow response to brain activity, which peaks and returnsto baseline over about 10 seconds, meaning even the most powerful scanner cannot improve on this. “It’s this noisy,sluggish proxy for neural activity,” said Huth. This hard limit has hampered the ability to interpret brain activity in response to natural speech because it gives a “mishmash of information” spread over a few seconds.【3】However, the advent of large language models – the kind ofAI underpinning OpenAI’s ChatGPT – provided a new way in. These models are able to represent, in numbers, the semantic meaning of speech, allowing the scientists to look at which patterns of neuronal activity corresponded to strings of words with a particular meaning rather than attempting to read out activity word byword. The learning process was intensive: three volunteers were required to lie ina scanner for 16 hours each, listening to podcasts. The decoder was trained to match brain activity to meaning using the large language model GPT-1, a precursor to ChatGPT. Later, the same participants were scanned listening to a new storyor imagining telling a story and the decoder was used to generate text from brain activity alone.【4】About half the time, the text closely – and sometimes precisely– matched the intended meanings of the original words. “Our system works at the level ofideas, semantics, meaning,” said Huth. “This is the reason why what we get out is not the exact words, it’s the gist.” For instance, when a participant was played the words: “I don’t have my driver’s licence yet,” the decoder translated as: “She has not even started to learn to drive yet.”【5】In another case, the words: “I didn’t know whether to scream, cry or run away. Instead, I said: ‘Leave me alone!’” was decoded as: “Started to scream and cry, and then she just said: ‘I told you to leave me alone.’” The participants were also askedto watch four short, silent videos while in the scanner, and the decoder was able to use their brain activity to accurately describe some of the content, the paper in Nature Neuroscience reported.【6】“For a non -invasive method, this is a real leap forward compared to what’s been done before, which is typically single words or short sentences,” Huth said. Jerry Tang, a doctoral student at the University of Texas at Austin and co-author, said: “We take very seriously the concerns that it could be used for bad purposes, and have worked to avoid that. “We want to make sure people only use these typesof technologies when they want to and that it helps them.”【7】Prof Shinji Nishimoto of Osaka University, whohas pioneered the reconstruction of visual images from brain activity, described the paper as a “significant advance”. He said: “This is a non-trivial finding and can be a basis for the development of brain-computer interfaces.” The team now hope to assess whether the technique could be applied to other, more portable brain-imaging systems, such as functional near-infrared spectroscopy (fNIRS).。

高考英语考前突破 阅读理解能力 文化教育 一口好牙或有助提高运动成绩素材
一口好牙或有助提高运动成绩Dentists say elite athletes could stand a better chance of winning gold medals if they look after their teeth.牙医称,优秀的运动员如果能好好对待自己的牙齿,那么他们获金牌的机会会更大。
The Oral Health and Performance in Sport conference in London heard that athletes' oral health was often bad and could impair training and performance.At the pinnacle of elite sport, the difference between winning and losing is tiny, so even marginal improvements can make a crucial difference.Doctors for Team GB's boxing squad are already trying to improve oral health.DisruptiveA study, published in the British Journal of Sports Medicine, showed a fifth of athletes said their oral health damaged their training and performance for the Games.At the conference, dentists said tooth pain could disrupt sleep and training and that inflammation of the gums could affect the rest of the body, impairing performance.It is not unusual for poor oral health to have wider effects. The NHS says it is linked to type 2 diabetes and heart problems.A regular floss(牙线), a bottle of mouthwash and good brushing technique are not going to transform a weekend jogger into an Olympian.However, Prof Ian Needleman, director of the International Centre for Evidence-Based Oral Health at University College London, says there could be an impact in elite sport.He told the BBC: "It's the accumulation of marginal gains, where the difference between elite athletes at the very top is small. Then oral health, amongst other aspects, could make a difference."The research we did at London 2012 found a large proportion of young athletes, fantastically well tuned physically, had really poor oral health."Quite a high proportion reported an impact on their training and performance so it's clearly an issue for them."。

Why Do We Make Weird Faces When We Taste Something Sour?为什么我们吃到酸的东西时会做出奇怪的表情?When you eat something really sour, the sensation isn't limited to your tongue. An especially tart bite has a way of making your entire face contract into a scrunched-up look of discomfort. If you can't resist puckering your mouth when you lick a lemon or snack on Sour Patch Kids, you can thank evolution.当你吃到很酸的东西时,你的感觉并不仅仅局限于舌头。
尤其是吃到特别酸的东西会让你的整张脸皱成一团,看起来很不舒服的样子。
如果你在吃到柠檬或很酸的食物时不由自主地要撅起嘴,那你得感谢进化。
That unmistakeable sour flavor that prickles you tastebuds is a product of the hydrogen ions that acids release when they combine with saliva. When your mouth detects this sign of acid, it lets you know in a dramatic way. Your taste receptors light up and your face twists involuntarily in what's known as a rejection response, according to Live Science.那种给你的味蕾带来明显刺痛感的酸味是酸与唾液结合时释放的氢离子产物。
关于口红效应的英文阅读理解
关于口红效应的英文阅读理解The "lipstick effect" is a theory that suggests during tough economic times, consumers will be more willing to buy less expensive luxury goods, such as lipstick, as a means of making themselves feel better. This term was first coined during the Great Depression in the 1930s when it was observed that despite the overall decline in consumer spending, the sales of cosmetics, particularly lipstick, remained strong.The lipstick effect is often attributed to the ideathat consumers may not be able to afford big-ticket luxury items during an economic downturn, but they still want to treat themselves to something that feels luxurious. Lipstick, being a relatively affordable luxury item, becomes a popular choice for consumers looking to indulgein a small, feel-good purchase.From a psychological perspective, the lipstick effect can be seen as a form of retail therapy. In times ofeconomic uncertainty, people may turn to small indulgences like lipstick to boost their mood and alleviate stress.This phenomenon reflects the human desire for comfort and self-care, even in challenging financial circumstances.Furthermore, the lipstick effect has implications for the beauty industry and consumer behavior. Companies may capitalize on this phenomenon by offering a range of affordable luxury beauty products during economic downturns, recognizing that consumers may still be willing to make discretionary purchases in this category.In conclusion, the lipstick effect refers to the tendency for consumers to purchase small luxury items like lipstick during tough economic times as a way to feel better. This phenomenon highlights the complex interplay between consumer psychology, economic conditions, andretail trends.。

The truth hurts 真相伤人Mar 31st 2010 | WASHINGTON, DC | From The Economist print editionWill the Treasury call China a currency manipulator?财政部会定义中国为货币操纵国吗?TO MOST people, to say that China holds down the value of its currency to boost its exports is to state the obvious. Not, though, to America’s Treasury Department. By law it must report twice a year on which countries fiddle their exchange rates at the world’s expense. China was last fingered in 1994. Ever since then, the Treasury has concluded that the designation would do more harm than good. Speculation is growing that it may decide differently in its next report, due on April 15th.对大多数人来说,说中国通过抑制人民币的价值,刺激出口,等于在陈述一个明显的事实。
然而对美国财政部来说,却不是这么简单。
法律规定它每隔两年对其它国家干涉汇率,危害他国的行为进行汇报。
中国曾在1994年列入汇率操纵国。
自那时候起,财政部得出结论:罗列中国,更多的是带来坏处。
外界猜测财政部可能将在4月15日的报告中推翻原先的结论。
The mood in America resembles that in 2005, when the Senate voted to hit China with tariffs of 27.5% and the Treasury ratcheted up its rhetoric. China abruptly moved to a managed float for the yuan. It was allowed to appreciate by 20% over the next three years before a halt was called during the banking panic of 2008.现在美国的感受类似2005年。

How spider silk avoids hungry bacteria蜘蛛丝是如何免于被饥肠辘辘的细菌蚕食的No antibiotics are involved它们并非以抗生素抗菌Tougher than any fibre made by humans and extraordinarily good at transmitting vibrations to the predators that weave it,spider silk has been a source of inspiration for the development of everything from scaffolding for regenerating bones to bulletproof vests,remote sensors and noise reducers.蜘蛛丝比任何人类制造的纤维都要坚韧,而且它还特别利于将震动传递给编织出它的捕食者。
从用于骨骼再生的支架到防弹背心,再从远程传感器到降噪器,蜘蛛丝一直是人类各种发明的灵感源泉。
Yet one of its most remarkable attributes,its resistance to decay,has received little attention.Some researchers speculate that spider silk keeps hungry bacteria at bay by being laced with antibiotics.然而,作为其最显著特性之一的抗腐坏性却很少受到人们的关注。
一些研究人员推测,蜘蛛丝是因为添加了抗生素才得以远离饥肠辘辘的细菌的。
But work by Wang Pi-Han and Tso I-Min at Tunghai University,in Taiwan, published in the Journal of Experimental Biology,suggests this is not thecase.Rather,silk manages to avoid being eaten by locking the nutrients it contains behind an impenetrable barrier.但据台湾东海大学的王必汉和曹一鸣发表在《实验生物学杂志》上的研究表明,事实并非如此。

Digest Of The. Economist.2006(6-7)Hard to digestA wealth of genetic information is to be found in the human gutBACTERIA, like people, can be divided into friend and foe. Inspired by evidence that the friendly sort may help with a range of ailments, many people consume bacteria in the form of yogurts and dietary supplements. Such a smattering of artificial additions, however, represents but a drop in the ocean. There are at least 800 types of bacteria living in the human gut. And research by Steven Gill of the Institute for Genomic Research in Rockville, Maryland, and his colleagues, published in this week's Science, suggests that the collective genome of these organisms is so large that it contains 100 times as many genes as the human genome itself.Dr Gill and his team were able to come to this conclusion by extracting bacterial DNA from the faeces of two volunteers. Because of the complexity of the samples,they were not able to reconstruct the entire genomes of each of the gut bacteria, just the individual genes. But that allowed them to make an estimate of numbers.What all these bacteria are doing is tricky to identify—the bacteria themselves are difficult to cultivate. So the researchers guessed at what they might be up to by comparing the genes they discovered with published databases of genes whose functions are already known.This comparison helped Dr Gill identify for the first time the probable enzymatic processes by which bacteria help humans to digest the complex carbohydrates in plants. The bacteria also contain a plentiful supply of genes involved in the synthesis of chemicals essential to human life—including two B vitamins and certain essential amino acids—although the team merely showed that these metabolic pathways exist rather than proving that they are used. Nevertheless, the pathways they found leave humans looking more like ruminants: animals such as goats and sheep that use bacteria to break down otherwise indigestible matter in the plants they eat.The broader conclusion Dr Gill draws is that people aresuperorganisms whose metabolism represents an amalgamation of human and microbial attributes. The notion of a superorganism has emerged before, as researchers in other fields have come to view humans as having a diverse internal ecosystem. This, suggest some, will be crucial to the success of personalised medicine, as different people will have different responses to drugs, depending on their microbial flora. Accordingly, the next step, says Dr Gill, is to see how microbial populations vary between people of different ages, backgrounds and diets.Another area of research is the process by which these helpful bacteria first colonise the digestive tract. Babies acquire their gut flora as they pass down the birth canal and take a gene-filled gulp of their mother's vaginal and faecal flora. It might not be the most delicious of first meals, but it could well be an important one.Zapping the bluesThe rebirth of electric-shock treatmentELECTRICITY has long been used to treat medical disorders. As early as the second century AD, Galen, a Greek physician, recommended the use of electric eels for treatingheadaches and facial pain. In the 1930s Ugo Cerletti and Lucio Bini, two Italian psychiatrists, used electroconvulsive therapy to treat schizophrenia. These days, such rigorous techniques are practised less widely. But researchers are still investigating how a gentler electric therapy appears to treat depression.Vagus-nerve stimulation, to give it its proper name, was originally developed to treat severe epilepsy. It requires a pacemaker-like device to be implanted in a patient's chest and wires from it threaded up to the vagus nerve on the left side of his neck. In the normal course of events, this provides an electrical pulse to the vagus nerve for 30 seconds every five minutes.This treatment does not always work, but in some cases where it failed (the number of epileptic seizures experienced by a patient remaining the same), that patient nevertheless reported feeling much better after receiving the implant. This secondary effect led to trials for treating depression and, in 2005, America's Food and Drug Administration approved the therapy for depression that fails to respond to all conventional treatments, including drugs and psychotherapy.Not only does the treatment work, but its effects appear to be long lasting. A study led by Charles Conway of Saint Louis University in Missouri, and presented to a recent meeting of the American Psychiatric Association, has found that 70% of patients who are better after one year stay better after two years as well.The technique builds on a procedure called deep-brain stimulation, in which electrodes are implanted deep into the white matter of patients' brains and used to “reboot” faulty neural circuitry. Such an operation is a big undertaking, requiring a full day of surgery and carrying a risk of the patient suffering a stroke. Only a small number of people have been treated this way. In contrast, the device that stimulates the vagus nerve can be implanted in 45 minutes without a stay in hospital.The trouble is that vagus-nerve stimulation can take a long time to produce its full beneficial effect. According to Dr Conway, scans taken using a technique called positron-emission tomography show significant changes in brain activity starting three months after treatment begins. The changes are similar to the improvements seen in patientswho undergo other forms of antidepression treatment. The brain continues to change over the following 21 months. Dr Conway says that patients should be told that the antidepressant effects could be slow in coming.However, Richard Selway of King's College Hospital, London, found that his patients' moods improved just weeks after the implant. Although brain scans are useful in determining the longevity of the treatment, Mr Selway notes that visible changes in the brain do not necessarily correlate perfectly with changes in mood.Nobody knows why stimulating the vagus nerve improves the mood of depressed patients, but Mr Selway has a theory. He believes that the electrical stimulation causes a region in the brain stem called the locus caeruleus (Latin, ironically, for “blue place”) to flood the brain with norepinephrine, a neurotransmitter implicated in alertness, concentration and motivation—that is, the mood states missing in depressed patients. Whatever the mechanism, for the depressed a therapy that is relatively safe and long lasting is rare cause for cheer.The shape of things to comeHow tomorrow's nuclear power stations will differ from today'sTHE agency in charge of promoting nuclear power in America describes a new generation of reactors that will be “highly economical” with “enhanced safety”, that “minimise wastes” and will prove “proliferation resistant”. No doubt they will bake a mean apple pie, too.Unfortunately, in the world of nuclear energy, fine words are not enough. America got away lightly with its nuclear accident. When the Three Mile Island plant in Pennsylvania overheated in 1979 very little radiation leaked, and there were no injuries. Europe was not so lucky. The accident at Chernobyl in Ukraine in 1986 killed dozens immediately and has affected (sometimes fatally) the health of tens of thousands at the least. Even discounting the association of nuclear power with nuclear weaponry, people have good reason to be suspicious of claims that reactors are safe.Yet political interest in nuclear power is reviving across the world, thanks in part to concerns about global warming and energy security. Already, some 441 commercial reactorsoperate in 31 countries and provide 17% of the planet's electricity, according to America's Department of Energy. Until recently, the talk was of how to retire these reactors gracefully. Now it is of how to extend their lives. In addition, another 32 reactors are being built, mostly in India, China and their neighbours. These new power stations belong to what has been called the third generation of reactors, designs that have been informed by experience and that are considered by their creators to be advanced. But will these new stations really be safer than their predecessors?Clearly, modern designs need to be less accident prone. The most important feature of a safe design is that it “fails safe”. Fo r a reactor, this means that if its control systems stop working it shuts down automatically, safely dissipates the heat produced by the reactions in its core, and stops both the fuel and the radioactive waste produced by nuclear reactions from escaping by keeping them within some sort of containment vessel. Reactors that follow such rules are called “passive”. Most modern designs are passive to some extent and some newer ones are truly so. However, some of the genuinely passive reactors are also likely to be moreexpensive to run.Nuclear energy is produced by atomic fission. A large atom (usually uranium or plutonium) breaks into two smaller ones, releasing energy and neutrons. The neutrons then trigger further break-ups. And so on. If this “chain reaction” can be controlled, the energy released can be used to boil water, produce steam and drive a turbine that generates electricity. If it runs away, the result is a meltdown and an accident (or, in extreme circumstances, a nuclear explosion—though circumstances are never that extreme in a reactor because the fuel is less fissile than the material in a bomb). In many new designs the neutrons, and thus the chain reaction, are kept under control by passing them through water to slow them down. (Slow neutrons trigger more break ups than fast ones.) This water is exposed to a pressure of about 150 atmospheres—a pressure that means it remains liquid even at high temperatures. When nuclear reactions warm the water, its density drops, and the neutrons passing through it are no longer slowed enough to trigger further reactions. That negative feedback stabilises the reaction rate. Can business be cool?Why a growing number of firms are taking global warming seriouslyRUPERT MURDOCH is no green activist. But in Pebble Beach later this summer, the annual gathering of executivesof Mr Murdoch's News Corporation—which last year led to a dramatic shift in the media conglomerate's attitude tothe internet—will be addressed by several leading environmentalists, including a vice-president turned climatechangemovie star. Last month BSkyB, a British satellite-television company chaired by Mr Murdoch and run by hisson, James, declared itself “carbon-neutral”, having taken various steps to cut or offset its discharges of carboninto the atmosphere.The army of corporate greens is growing fast. Late last year HSBC became the first big bank to announce that itwas carbon-neutral, joining other financial institutions, including Swiss Re, a reinsurer, and Goldman Sachs, aninvestment bank, in waging war on climate-warming gases (of which carbon dioxide is the main culprit). Last yearGeneral Electric (GE), an industrial powerhouse, launched its “Ecomagination” strategy, aiming to cut its outputofgreenhouse gases and to invest heavily in clean (ie, carbon-free) technologies. In October Wal-Mart announced aseries of environmental schemes, including doubling the fuel-efficiency of its fleet of vehicles within a decade.Tesco and Sainsbury, two of Britain's biggest retailers, are competing fiercely to be the greenest. And on June 7thsome leading British bosses lobbied Tony Blair for a more ambitious policy on climate change, even if that involvesharsher regulation.The greening of business is by no means universal, however. Money from Exxon Mobil, Ford and General Motorshelped pay for television advertisements aired recently in America by the Competitive Enterprise Institute, with thedaft slogan “Carbon dioxide: they call it pollution; we call it life”. Besides, environmentalist critics say, some firmsa re engaged in superficial “greenwash” to boost the image of essentially climate-hurting businesses. Take BP, themost prominent corporate advocate of action on climate change, with its “Beyond Petroleum” ad campaign, highprofileinvestments in green energy, and even a “carbon calculator” on its website that helps consumers measuretheirpersonal “carbon footprint”, or overall emissions of carbon. Yet, critics complain, BP's recent record profits arelargely thanks to sales of huge amounts of carbon-packed oil and gas.On the other hand, some free-market thinkers see the support of firms for regulation of carbon as the latestattempt at “regulatory capture”, by those who stand to profit from new rules. Max Schulz of the ManhattanInstitute, a conservative think tan k, notes darkly that “Enron was into pushing the idea of climate change, becauseit was good for its business”.Others argue that climate change has no more place in corporate boardrooms than do discussions of other partisanpolitical issues, such as Darfur or gay marriage. That criticism, at least, is surely wrong. Most of the corporateconverts say they are acting not out of some vague sense of social responsibility, or even personal angst, butbecause climate change creates real business risks and opportunities—from regulatory compliance to insuringclients on flood plains. And although these concerns vary hugely from one company to the next, few firms can besure of remaining unaffected.Testing timesResearchers are working on ways to reduce the need for animal experiments, but new laws mayincrease the number of experiments neededIN AN ideal world, people would not perform experiments on animals. For the people, they are expensive. For theanimals, they are stressful and often painful.That ideal world, sadly, is still some way away. People need new drugs and vaccines. They want protection fromthe toxicity of chemicals. The search for basic scientific answers goes on. Indeed, the European Commission isforging ahead with proposals that will increase the number of animal experiments carried out in the EuropeanUnion, by requiring toxicity tests on every chemical approved for use within the union's borders in the past 25years.Already, the commission has identified 140,000 chemicals that have not yet been tested. It wants 30,000 of theseto be examined right away, and plans to spend between €4 billion-8 billion ($5 billion-10 billion) doing so. Thenumber of animals used for toxicity testing in Europe will thus, experts reckon, quintuple from just over 1m ayearto about 5m, unless they are saved by some dramatic advances in non-animal testing technology. At the moment,roughly 10% of European animal tests are for general toxicity, 35% for basic research, 45% for drugs andvaccines, and the remaining 10% a variety of uses such as diagnosing diseases.Animal experimentation will therefore be around for some time yet. But the hunt for substitutes continues, and lastweekend the Middle European Society for Alternative Methods to Animal Testing met in Linz, Austria, to reviewprogress.A good place to start finding alternatives for toxicity tests is the liver—the organ responsible for breaking toxicchemicals down into safer molecules that can then be excreted. Two firms, one large and one small, told themeeting how they were using human liver cells removed incidentally during surgery to test various substances forlong-term toxic effects.PrimeCyte, the small firm, grows its cells in cultures over a few weeks and doses them regularly with the substanceunder investigation. The characteristics of the cellsare carefully monitored, to look for changes in theirmicroanatomy.Pfizer, the big firm, also doses its cultures regularly, but rather than studying individual cells in detail, it counts cellnumbers. If the number of cells in a culture changes after a sample is added, that suggests the chemical inquestion is bad for the liver.In principle, these techniques could be applied to any chemical. In practice, drugs (and, in the case of PrimeCyte,food supplements) are top of the list. But that might change if the commission has its way: those140,000screenings look like a lucrative market, although nobody knows whether the new tests will be ready for use by2009, when the commission proposes that testing should start.Other tissues, too, can be tested independently of animals. Epithelix, a small firm in Geneva, has developed anartificial version of the lining of the lungs. According to Huang Song, one of Epithelix's researchers, thefirm'scultured cells have similar microanatomy to those found in natural lung linings, and respond in the same way tovarious chemical messengers. Dr Huang says that theycould be used in long-term toxicity tests of airbornechemicals and could also help identify treatments for lung diseases.The immune system can be mimicked and tested, too. ProBioGen, a company based in Berlin, is developing anartificial human lymph node which, it reckons, could have prevented the near-disastrous consequences of a drugtrial held in Britain three months ago, in which (despite the drug having passed animal tests) six men sufferedmultiple organ failure and nearly died. The drug the men were given made their immune systems hyperactive.Such a response would, the firm's scientists reckon, have been identified by their lymph node, which is made fromcells that provoke the immune system into a response. ProBioGen's lymph node could thus work better than animaltesting.Another way of cutting the number of animal experiments would be tochange the way that vaccines are tested, according to CoenraadHendriksen of the Netherlands Vaccine Institute. At the moment, allbatches of vaccine are subject to the same battery of tests. DrHendriksen argues that this is over-rigorous. When new vaccine culturesare made,belt-and-braces tests obviously need to be applied. But if abatch of vaccine is derived from an existing culture, he suggests that itneed be tested only to make sure it is identical to the batch from which itis derived. That would require fewer test animals.All this suggests that though there is still some way to go before drugs,vaccines and other substances can be tested routinely on cells ratherthan live animals, useful progress is being made. What is harder to see ishow the use of animals might be banished from fundamental research.Anger managementTo one emotion, men are more sensitive than women MEN are notoriously insensitive to the emotional world around them. At least, that is the stereotype peddled by athousand women's magazines. And a study by two researchers at the University of Melbourne, inAustralia,confirms that men are, indeed, less sensitive to emotion than women, with one important and suggestiveexception. Men are acutely sensitive to the anger of other men.Mark Williams and Jason Mattingley, whose study hasjust been published in Current Biology, looked at the way aperson's sex affects his or her response to emotionally charged facial expressions. People from all cultures agreeon what six basic expressions of emotion look like. Whether the face before you is expressing anger, disgust, fear,joy, sadness or surprise seems to be recognised universally—which suggests that the expressions involved areinnate, rather than learned.Dr Williams and Dr Mattingley showed the participants in their study photographs of these emotional expressions inmixed sets of either four or eight. They asked the participants to look for a particular sort of expression, andmeasured the amount of time it took them to find it. The researchers found, in agreement with previous studies,that both men and women identified angry expressions most quickly. But they also found that anger was morequickly identified on a male face than a female one.Moreover, most participants could find an angry face just as quickly when it was mixed in a group of eightphotographs as when it was part of a group of four. That was in stark contrast to the other five sorts ofexpression,which took more time to find when they had to be sorted from a larger group. This suggests that something in thebrain is attuned to picking out angry expressions, and that it is especially concerned about angry men. Also, thishighly tuned ability seems more important to males than females, since the two researchers found that men pickedout the angry expressions faster than women did, even though women were usually quicker than men to recognizeevery other sort of facial expression.Dr Williams and Dr Mattingley suspect the reason for this is that being able to spot an angry individual quickly hasa survival advantage—and, since anger is more likely to turn into lethal violence in men than in women, the abilityto spot angry males quickly is particularly valuable.As to why men are more sensitive to anger than women, it is presumably because they are far more likely to getkilled by it. Most murders involve men killing other men—even today the context of homicide is usually aspontaneous dispute over status or sex.The ability to spot quickly that an alpha male is in a foul mood would thus have great survival value. It wouldallowthe sharp-witted time to choose appeasement, defence or possibly even pre-emptive attack. And, if it is right, thisstudy also confirms a lesson learned by generations of bar-room tough guys and schoolyard bullies: if you wantattention, get angry.The shareholders' revoltA turning point in relations between company owners and bosses?SOMETHING strange has been happening this year at company annual meetings in America:shareholders have been voting decisively against the recommendations of managers. Until now, mostshareholders have, like so many sheep, routinely voted in accordance with the advice of the people theyemploy to run the company. This year managers have already been defeated at some 32 companies,including household names such as Boeing, ExxonMobil and General Motors.This shareholders' revolt has focused entirely on one issue: the method by which members of the boardof directors are elected. Shareholder resolutions on other subjects have mostly been defeated, as usual.The successful resolutionscalled for directors to be elected by majority voting, instead of by thetraditional method of “plurality”—which in practice meant that only votes cast in favour were counted,and that a single vote for a candidate would be enough to get him elected.Several companies, led by Pfizer, a drug giant, saw defeat looming and pre-emptively adopted a formalmajority-voting policy that was weaker than in the shareholder resolution. This required any director whofailed to secure a majority of votes to tender his resignation to the board, which would then be free todecide whether or not to accept it. Under the shareholder resolution, any candidate failing to secure amajority of the votes cast simply would not be elected. Intriguingly, the shareholder resolution wasdefeated at four-fifths of the firms that adopted a Pfizer-style majority voting rule, whereas it succeedednearly nine times out of ten at firms retaining the plurality rule.Unfortunately for shareholders, their victories may prove illusory, as the successful resolutions wereall“precatory”—meaning that they merely advised management on the course of action preferredbyshareholders, but did not force managers to do anything. Several resolutions that tried to imposemajority voting on firms by changing their bylaws failed this year.Even so, wise managers should voluntarily adopt majority voting, according to Wachtell, Lipton, Rosen &Katz, a Wall Street law firm that has generally helped managers resist increases in shareholder power butnow expects majority voting eventually to “become universal”. It advises that, at the very least,managers should adopt the Pfizer model, if only to avoid becoming the subject of even greater scrutinyfrom corporate-governance activists. Some firms might choose to go further, as Dell and Intel have donethis year, and adopt bylaws requiring majority voting.Shareholders may have been radicalised by the success last year of a lobbying effort by managersagainst a proposal from regulators to make it easier for shareholders to put up candidates in boardelections. It remains to be seen if theywill be back for more in 2007. Certainly, some of the activistshareholders behind this year's resolutions have big plans. Where new voting rules are in place, they plancampaigns to vote out the chairman of the compensationcommittee at any firm that they think overpaysthe boss. If the 2006 annual meeting was unpleasant for managers, next year's could be far worse.Intangible opportunitiesCompanies are borrowing against their copyrights, trademarks and patentsNOT long ago, the value of companies resided mostly in things you could see and touch. Today it liesincreasingly in intangible assets such as the McDonald's name, the patent for Viagra and the rights toSpiderman. Baruch Lev, a finance professor at New York University's Stern School of Business, puts theimplied value of intangibles on American companies' balance sheets at about $6 trillion, or two-thirds ofthe total. Much of this consists of intellectual property, the collective name for copyrights, trademarksand patents. Increasingly, companies and their clever bankers are using these assets to raise cash.The method of choice is securitisation, the issuing of bonds based on the various revenues thrown off byintellectual property. Late last month Dunkin' Brands, owner of Dunkin' Donuts, a snack-bar chain, raised$1.7billion by selling bonds backed by, among other things, the royalties it will receive from itsfranchisees. The three private-equity firms that acquired Dunkin' Brands a few months ago have used thecash to repay the money they borrowed to buy the chain. This is the biggest intellectual-propertysecuritisation by far, says Jordan Yarett of Paul, Weiss, Rifkind, Wharton & Garrison, a law firm that hasworked on many such deals.Securitisations of intellectual property can be based on revenues from copyrights, trademarks (such aslogos) or patents. The best-known copyright deal was the issue in 1997 of $55m-worth of “Bowie Bonds”supported by the future sales of music by David Bowie, a British rock star. Bonds based on the films ofDreamWorks, Marvel comic books and the stories of John Steinbeck have also been sold. As well asDunkin' Brands, several restaurant chains and fashion firms have issued bonds backed by logos andbrands.Intellectual-property deals belong to a class known as operating-asset securitisations. These differ fromstandard securitisations of future revenues, such as bonds backed by the payments on a 30-yearmortgage or a car loan, in that theborrower has to make his asset work. If investors are to recoup theirmoney, the assets being securitised must be “actively exploited”, says Mr Yarett: DreamWorks mustcontinue to churn out box-office hits.The market for such securitisations is still small. Jay Eisbruck, of Moody's, a rating agency, reckons thataround $10 billion-worth of bonds ar e outstanding. But there is “big potential,” he says, pointing out thatlicensing patented technology generates $100 billion a year and involves thousands of companies.Raising money this way can make sense not only for clever private-equity firms, but also for companieswith low (or no) credit ratings that cannot easily tap the capital markets or with few tangible assets ascollateral for bank loans. Some universities have joined in, too. Yale built a new medical complex withsome of the roughly $100m it raised securitising patent royalties from Zerit, an anti-HIV drug.It may be harder for investors to decide whether such deals are worth their while. They are, after all,highly complex and riskier than standard securitisations. The most obvious risk is that the investorscannot be sure that the assets。

too many teeth阅读理解答案
too many teeth阅读理解答案Many Americans harbour a grossly distorted and exaggerated view of most of the risks surrounding food. Fergus Clydesdale, hea d of the department of food science and nutrition at the University ofMassachusettsAmherst, says bluntly that if the dangers from bact erially contaminated chicken were as great as some people believe, “the streets would be littered with people lying here and there.”Though the public increasingly demands no-risk food, there is no such thing. Bruce Ames, chairman of the bioc hemistry department at the University of California, Berkeley, point s out that up to 10% of a plant’s weight is made up of natural pes ticides (杀虫剂). Says he:“Since plants do not have jaws or teeth to protect themselves, they employ chemical warfare.” And many naturally produced ch emicals, though occurring in tiny amounts, prove in laboratory tess tobestrongcarcinogensa substance which can cause cancer. Mushr ooms (菇) might be banned if they were judged by the same stand ards that apply to food additives (剂). Declares Christina Stark, a nutritionist at Cornell University:“We’ve got fat worse natural chemicals in the food supply t han anything man-made.”Yet the issues are not that simple. While Americans have no re ason to be terrified to sit down at the dinner table, they have every reason to demand significant improvements in food and water saf ety. They unconsciously and unwillingly take in too much of too m any dangerous chemicals. If food already contains natural carcinog ens, it does not make much sense to add dozens of new man-made ones. Though most people will withstand the small amounts of contaminants generally found in food and water, at least a few i ndividuals will probably get cancer one day be cause of what they eat and drink.To make good food and water supplies even better, the Gover nment needs to tighten its regulatory standards, stiffen its inspecti on program and strengthen its enforcement policies. The food ind ustryshould modify some longaccepted practices or turn to less ha zardous alternatives. Perhaps most important, consumers will have to do a better job of learning how to handle and cook food properly. The problems that need to be tackled exist all along the food-supply chain, from fields to processing plants to kitchens.1、 What does the author think of the Americans’ view of the ir food?A) They overstate the government’s interference with the f ood industry.B)They are overoptimistic about the safety of their food.C) They overestimate the hazards of their food.D) They overlook the risks of the food they eat.2、The author considers it impossible to obtain no-risk food because ________.A) no food is free from pollution in the environmentB) pesticides are widely used in agricultureC) many vegetables contain dangerous natural chemicalsD) almost all foods have additives3、 By saying “they employ chemical warfare”(Line 4, Para.2) , Bruce Ames means “________”.A) plants produce certain chemicals to combat pests and disea sesB) plants absorb useful chemicals to promote their growthC)farmersusemanmade chemicals to dissolve the natural chemi cals in plantsD) farmers use chemicals to protect plants against pests and di seases4、 The reduction of the possible hazards in food ultimately de pends on ________.A) the governmentB) the consumerC) the processorD) the grower5、What is the message the author wants to convey in the passage?A) Eating and drinking have become more hazardous than before.B)B) Immediate measures must be taken to improve food prod uction and processing.C) Health food is not a dream in modern society.D) There is reason for caution but no cause for alarm with rega rd to food consumption.答案:1、D2、A3、C4、C5、B。
与牙齿英语作文
与牙齿英语作文Teeth are an essential part of our body and play a crucialrole in our daily lives. They help us chew food, speakclearly, and even contribute to our facial appearance. Here's a composition on teeth in English:The Importance of TeethTeeth are not just a set of hard structures in our mouth;they are vital tools for our survival and social interactions. They allow us to enjoy a wide variety of foods, from the softest fruits to the hardest nuts. Without them, our diet would be severely limited, and our ability to digest food would be compromised.Functionality and HealthFirst and foremost, teeth are designed for mastication, the process of breaking down food into smaller pieces. This not only makes it easier to swallow but also aids in thedigestive process. The incisors are perfect for biting into food, the canines for tearing, and the molars for grinding. This division of labor ensures that we can process a diverse diet.Moreover, teeth are indicators of overall health. Healthyteeth and gums are often a sign of a well-balanced diet and good oral hygiene. Conversely, dental problems such as cavities and gum disease can be a sign of underlying health issues.Aesthetic ValueBeyond their functional role, teeth also play a significant part in our appearance. A bright, healthy smile can boostself-confidence and make a positive impression on others. In many cultures, a beautiful smile is considered an attractive feature and can influence social and professional success.Oral HygieneMaintaining good oral hygiene is crucial for the health of our teeth. Regular brushing with fluoride toothpaste, flossing, and dental check-ups are essential practices. These habits help to prevent plaque buildup, which can lead to tooth decay and gum disease.Dental Care ProfessionThe dental care profession is dedicated to the health and maintenance of teeth. Dentists provide a range of services from routine cleanings to complex procedures such as root canals and dental implants. They also educate patients on the importance of oral hygiene and the steps they can take to protect their teeth.ConclusionIn conclusion, teeth are not just for eating; they are integral to our health, comfort, and social interactions. Taking care of our teeth should be a priority, as neglect can lead to pain, infection, and even tooth loss. By understanding the importance of teeth and practicing goodoral hygiene, we can enjoy the benefits of a healthy and attractive smile throughout our lives.This composition touches on the multifaceted importance of teeth in our lives, from their role in digestion to their impact on our social interactions and self-esteem.。
双语阅读 牙医的批评
双语阅读牙医的批评Ten days ago, I received some pretty harsh criticism. I took it on the chin, and accepted that my performance had been sloppy, substandard and was storing up trouble for the future.As a result, I have made some big changes: I am more focused and pay greater attention to detail than before. I am grateful to the person for telling me just how badly I was doing and am optimistic that my new behaviour will eventually yield results.Re-reading the above paragraph, I'd like to make one small correction. I didn't actually take the criticism on the chin. I took it in the mouth, as that is where it was aimed.The criticism was delivered by my dental hygienist and followed a long poke-about in and around my gum margins. She declared that in some areas my flossing and work with the interdental brushes was so incompetently executed that unless I reformed, I could lose my back teeth. Every day since then, I have been hard at it with sixdifferent pieces of kit. It is a major undertaking but one to which I am sincerely committed.This business of learning from criticism is a new thing for me. So new, in fact, that I don't think I can remember a single occasion in my working life when I have listened to an account of my failings with such good grace and wholeheartedly tried to change.Mostly, when I'm criticised, one of two things happens. Either I slip down into a well of self-doubt from which no action is possible, or I feel an instant surge of resentment and, when that dies down, an attempt to justify myself or to denigrate my critic takes its place. At this point, I may enlist others to help me assemble an alternative reality in which the critic is in the wrong and I am splendidly, undeniably in the right.Usually the process stops there. Very occasionally, a few days later I start to wonder if maybe they could have a point after all. Yet even then, the following step – a corresponding change in behaviour – seems always to elude me.I know I'm not alone in this. I have been asking people for the past week to tell me about times when they have accepted criticism and changed. They all claimed to welcome negative feedback, even whenpainful. But when pressed, few could name any change made as a result – or, if they could, it turned out to be something piffling such as no longer splitting infinitives after having been told off for doing so.So what was it about my session in the dentist's chair that was so different? I have thought about this in the fallow hours spent attending to my gums last week and come up with six conditions that explain why the criticism brought change.First, my hygienist presented me with a causal chain that was hard to dispute. Bad brushing leads to loss of teeth. The only way out is to brush better.Second, she had no hidden agenda. Her goal was the same as mine –for my teeth to remain in situ for as long as possible.Third, I recognised her as an authority on the subject, as she has spent two decades scraping around in people's mouths.Fourth (and this is really important) I do not equate myself with my flossing methodology. To attack the latter is not to imply I am aterrible employee or horrid person.Fifth, she showed me exactly how to do better and offered hints as I amateurishly tried it myself.Ten days ago, I received some pretty harsh criticism.

And the only reason that I'm not going to dothat is because I get quite a few of these attacks so my skin is more leathery than it used to be.In hope of further tips on how to take criticism I have scanned the web. “Feedback is the breakfast of champions,” say the self-help sites.Only it isn't. It is the breakfast of weirdos, of ambitious freaks.I know this because I have spent many hours watching reality TV shows such as The Apprentice and America's Next Top Model. Every week the judges hand out savage criticism to the contestants. Every week,their faces barely flinch. The following week the same contestantsreturn with new accents, new jaw lines, new walks and new attitudes just to please their critics.So this is the real secret to taking criticism. What you need is not the humility and level-headedness to listen to another's point of view. Instead, you need to be so focused on succeeding at something that you swallow your pride and do whatever you are told.Which leads me to an unlooked-for parallel between me and the young catwalk wannabes on America's Next Top Model. They desperately want to be a cover girl; I desperately want to keep my teeth. And if that means spending 15 minutes a day juggling four interdental brushes, then so be it.十天前,我受到了一些颇为严厉的批评。

Not as close as lips and teeth China should not fear India’s growing friendship with VietnamOct 22nd 2011 | from the print editionWHEN China’s sovereignty is at issue Global Times, a Beijing newspaper, does not mince words. In September it growled that a contract between Vietnam and an Indian state-owned oil-and-gas company, ONGC, to explore in Chinese-claimed waters in the South China Sea would “push China to the limit”. Yet this month India and Vietnam have reached an agreement on “energy co-operation”. Global Times is incensed that this was signed just a day after Vietnam, during a visit to Beijing by the head of its communist party, Nguyen Phu Trong, had agreed with China on “ground rules” for solving maritime squabbles. Now, thundered the paper, “China may consider taking actions to show its stance and prevent more reckless attempts in confronting China.”The more sober China Energy News, a publication of the Communist Party’s People’s Daily, has weighed in, warning India that its “energy strategy isslipping into an extremely dangerous whirlpool.” Behind such fulminations lie two C hinese fears. One is that India’s involvement complicates its efforts to have its way in the tangled territorial disputes in the South China Sea. Thesecond is that India and Vietnam are seeking closer relations as part of an American-led strategy to contain China. Even if the first worry has some basis, fears of containment are overblown.As Mr Trong was in China, however, Vietnam’s president, Truong Tan Sang, was in India, to pursue the two countries’ “strategic partnership”. Paranoid Chinese nationalists could be forgiven for feeling ganged up on. After all, ignoring the border clashes with the former Soviet Union in 1969, these were the countries on the other side of China’s two most recent wars. In both Delhi and Hanoi the experience of brief “punitive” invasion by China respectively still colours attitudes. India was humiliated by China’s foray into what is now Arunachal Pradesh in 1962. Vietnam’s fierce response to the Chinese invasion of 1979 has become part of national legend of perpetual resistance to Chinese domination.Vietnam still claims the Paracel islands in the South China Sea, from which China evicted it in 1974, as well as the much-contested Spratlys to the south, where over 70 Vietnamese sailors died in clashes with China in 1988. Tension in the area remains high. Earlier this year, after a Vietnamese ship had its surveying cables cut by a Chinese patrol boat, hundreds joined anti-China protests in Hanoi and Ho Chi Minh City.So Vietnam welcomes India’s support, just as it was buoyed last year by America’s declaration, aimed at China’s perceived assertiveness, of a “national interest” in freedom of navigation in the South China Sea. Of Vietnam’s partners in the Association of South-East Asian Nations, Brunei, Malaysia and the Philippines also have partial claims in the sea. Vietnam naturally would like to present as united a front as possible against China’s claims.It is against this background that some Indian strategists see an opportunity: Vietnam could be “India’s Pakistan”, a loyal all y, as Pakistan is for China, that exerts indirect, debilitating pressure on its strategic rival. Harsh Pant, a professor of defence studies at King’s College, London, argues that Vietnam offers India an entry-point, through which it can “penetrate China’s periphery”.Tweaking China appeals to Indian diplomats, who habitually complain that their big neighbour refuses to make room for their own country’s rise. Behind that resentment lurks irritation at China’s effort to exert influence in India’s own backyard, not just through its “all-weather” friendship with Pakistan, but in Bangladesh, Myanmar, Nepal and Sri Lanka as well. Indeed, on Mr Sang’s heels in India came Myanmar’s president, Thein Sein, as Indiaattempts to make up diplomatic ground it has lost to China.India also wants to push back against what it sees as Chinese provocations. Among these is the apparent Chinese stoking of the unresolved territorial disputes that led to the 1962 war. In recent years it has revived its claim to most of Arunachal Pradesh. No wonder backing Vietnamese claims in the South China Sea appeals to some Indian hawks. Already, in July, an Indian naval ship off Vietnam ignored a radio warning, apparently from theChinese navy, that it was entering Chinese waters.China resents anything that smacks of efforts to thwart its rise as a global power. Talk of India’s selling Vietnam the BrahMos missiles it has developed jointly with Russia is still speculative. But Chinese strategists will fret about the purpose of the regular “security dialogue” agreed on during Mr Sang’s visit. It comes as Indian press reports suggest India has decided to deploy BrahMos missiles in Arunachal, pointed at Chinese-controlled Tibet. Behind India’s assertiveness and its closer ties with Vietnam, China de tects America’s hand. In July Hillary Clinton, the secretary of state, urged India “to engage east and act east as well”. Vietnam’s VietnamBut to see India and Vietnam as compliant partners in an American-orchestrated anti-China front is off the mark for three reasons. Both countries are fiercely independent. Neither is going to do America’s bidding, and Vietnam is certainly not going to be India’s Pakistan. Second, their relations are about far more than China. They go back centuries (it is Indo-China, after all) and have been improving for decades. Sanjaya Baru, editor of the Business Standard, an Indian newspaper, and former spokesman for the prime minister, has called it “perhaps the most well-rounded bilateralrelationship that India has with any count ry”.Third, both insist—plausibly—that they want good relations with China, now India’s biggest trading partner. And after all, Mr Trong was in China even as Mr Sang was in India. Hu Jintao, China’s president, was reported as counselling Vietnam to “stick to using dialogue and consultations to handle properly problems in bilateral relations.” Of course, if China itself had been consistent in following Mr Hu’s advice, the improvement in relations between India and Vietnam might not have such an impetus behind it, and, viewed from Beijing, might seem far less sinister.。
