Treasure Fever

A)Most visitors come to Cape Canaveral, on the northeast coast （海岸）of Florida, for the tourist attractions. It's home to the second-busiest（第二的） cruise ship port（邮轮港口） in the world and is a gateway to the cosmos.（宇宙 ）Nearly 1.5 million visitors flock here every year to watch rockets, spacecraft, and satellites blast off into the solar system from Kennedy Space Center Visitor Complex.Nearly 64 kilometers of undeveloped beach and 648 square kilometers of protected refuge（保护区） fan out from the cape's sandy shores（沙滩 ）.

B)Yet some of Cape Canaveral's most legendary（传说） attractions lie unseen, wedged under the sea's surface in mud and sand, for this part of the world has a reputation as a deadly ship trap.Over the centuries, dozens of majestic Old World sailing ships smashed（破碎的） and sank on this irregular stretch （延伸）of windy Florida coast.They were vessels （船舶）built for war and commerce, crossing the globe carrying everything from coins to cannons（大炮）, boxes of silver and gold, chests of jewels（珠宝） and porcelain（瓷器）, and pearls（珍珠） from the Caribbean.

C)Cape Canaveral contains one of the greatest concentrations （集中）of colonial（殖民地的） shipwrecks in the world.In recent years, advances in radar, diving（潜水 ）, detection equipment, computers, and GPS have transformed the hunt. The naked eye might see a pile of rocks, but technology can reveal the precious artifacts（古董) that lie hidden on the ocean floor.

D) As technology renders the seabed（海底） more accessible, the hunt（打捞） for treasure-filled ships has drawn a fresh tide of salvors and their investors - as well as marine archaeologists （考古学家）wanting to bring to light the lost（迷失的） relics（遗迹）. But of late, when salvors（救援人员） have found vessels（船舶）, their rights have been challenged in court.（法院）The big question: who should have control of these treasures?

E) High-stakes （高风险）fights over shipwrecks pit archaeologists against treasure hunters in a vicious cycle（恶循环） of accusations. Archaeologists regard themselves as protectors of history, and they see salvors as careless destroyers.Salvors feel they do the hard work of searching for ships, only to have them stolen from under them when discovered.This kind of clash （冲突）inevitably takes place on a grand scale.Aside from the salvors, their investors, and the maritime archaeologists who serve as expert witnesses, the battles sweep（席卷） in local and international governments and organizations like UNEScO that work to protect under-water heritage.

The court cases that ensue stretch（持续） on for years.Are finders keepers, or do the ships belong to the countries that made them and sent them sailing （航行）centuries ago? Where once salvors and archaeologists worked side by side（并肩）, now they belong to opposing（对立）, and equally contemptuous（轻蔑的）, tribes.

F)Nearly three million vessels lie wrecked on the Earth's ocean floor - from old canoes to the Titanic - and likely less than one percent have been explored.Some -- like an ancient Roman ship found off Antikythera, Greece, dated between 70 and 60 BC and carrying astonishingly （惊人的）sophisticated（精密的） gears（齿轮） and dials for navigating（航行 ） by the sun - are critical to a new understanding of our past.No wonder there is an eternal （永恒的）stirring（激发） among everybody from salvors to scholars（学者） to find them.

G)In May 2016, a salvor named Bobby Pritchett, president of Global Marine Exploration (GME) in Tampa, Florida, announced that he had discovered scattered（分散的） remains of a ship buried a kilometer off Cape Canaveral.Over the prior three years, he and his crew（团队） had obtained 14 state permits to survey a nearly 260-square-kilometer area off the cape; they worked 250 days a year, backed by investor funds of, he claims, US $4 million.It was hard work.Crew members were up at dawn（黎明）, dragging sensors （传感器）from their expedition vessels （探险船）back and forth, day in and day out, year after year, to detect metal of any kind.

Using computer technology, Pritchett and his crew created intricate（复杂的）, color-coded maps marked with the GPS coordinates（坐标） of thousands of finds, all invisible under a meter of sand.

H) One day in 2015, the magnetometer（磁力计） picked up metal that turned out to be an iron cannon（大炮 ）; when the divers blew the sand away, they also discovered a more precious bronze （青铜）cannon with markings indicating French royalty（皇室） and, not far off, a famous marble（大理石 ） column（石柱） carved with the coat of arms of France, known from historical paintings.The discovery was cause for celebration.The artifacts indicated （表明）the divers had likely found the wreck of La Trinité, a 16th-century French vessel（船舶） that had been at the center of a bloody battle between France and Spain that changed the fate（命运 ） of the United States of America.

I)And then the legal storm began, with GME and Pritchett pitted against Florida and France.

The Sunken Military Craft Act of 2004, a US federal act, protects any vessel that was on a military （军事）mission, allowing the originating country to claim their ship even centuries later.

In 2018, two long years after Pritchett's discovery, the federal district （地方）court ruled（裁决 ） in favor of France.For Pritchett, the decision was devastating.（毁灭性的）Millions of dollars of investor funding and years of labor were lost.

J)But this is far from the first time a salvor has lost all rights to a discovery.In 2012, for instance, Spain won a five-year legal battle against Odyssey Marine Exploration, which had hauled （打捞）594,000 gold and silver coins from a Spanish wreck off the coast of Portugal across the Atlantic to the United States."Treasure hunters can be naive（天真）," says attorney（律师） David Concannon, who has had several maritime archaeologists as clients and represented two sides in the battles over the Titanic for 20 years."Many treasure hunters don't understand they are going to have to fight for their rights against a government that has an endless supply of money for legal battles that treasure hunters are likely to lose."

K) Putting an inflated （抬高 ）price on artifacts rather than viewing them as cultural and historical treasures that transcend （超过）any price is what irritates（使恼怒） many archaeologists.For the archaeologist, everything in a wreck matters - hair, fabric, a fragment of a newspaper, rat bones - all things speak volumes.Archaeologists don't want artifacts ending up in a private collection instead of taking humanity on a journey of understanding.

L) George Bass is one of the pioneers of under-water archaeology, and a researcher at Texas A&M University. He has testified（作证） in court against treasure hunters, but says archaeology is not without its own serious problems.He believes archaeologists need to do a better job themselves instead of routinely （常规的）criticizing treasure hunters."Archaeology has a terrible reputation（名誉） for not publishing enough on its excavations and finds," he says.Gathering data, unearthing and meticulously preserving and examining finds, verifying（验证） identity and origin, piecing（修补） together the larger story, and writing and publishing a comprehensive paper or book can take decades.A bit cynically（冷笑的）, Bass describes colleagues who never published because they waited so long they became ill or died. Who is more at fault, Bass asks, the professional archaeologist who carefully excavates （发掘）a site and never publishes on it or the treasure hunter who locates a submerged wreck, salvages （打捞）part, conserves part, and publishes a book on the operation?

M) Pritchett concedes （承认 ）that his find deserves careful excavation（挖掘） and preservation."I think what I found should go in a museum," he says."But I also think I should get paid for what I found."Indeed, it's a bit of a mystery（令人费解） why governments, archaeologists, and treasure hunters can't work together - and why salvors aren't at least given a substantial finder's fee before the original owner takes possession of the vessel and its artifacts.

1.Exploration of shipwrecks on the sea floor is crucial in updating our understanding of humanity's past.

2.Quite a number of majestic（宏伟的） ships sailing from Europe to America were wrecked off the Florida coast over the cent- uries.

3.Pritchett suffered a heavy loss when a US district court ruled against him.

4.Recently, people who found treasures in shipwrecks have been sued （被起诉）over their rights to own them.

5.Pritchett claims he got support of millions of dollars from investors for his shipwreck exploration.

6.One pioneer marine scientist thinks archaeologists should make greater efforts to publish their findings.

7.With technological advancement in recent years, salvors now can detect the invaluable man-made objects lying buried under the sea.

8.According to a lawyer, many treasure hunters are susceptible（易受影响的） to loss because they are unaware they face a financially stronger opponent in court.

9.Salvors of treasures in sunken ships and marine archaeologists are now hostile（敌对） to each other.

10.Archaeologists want to see artifacts help humans understand their past instead of being sold to private collectors at an outrageous （令人吃惊的）price.

Can Learning a Foreign Language Prevent Dementia?

A) You may have heard that learning another language is one method for preventing or at least postponing the onset of dementia（痴呆症）.Dementia refers to the loss of cognitive abilities, and one of its most common forms is Alzheimer's（阿尔茨海默症） disease.At this time, the causes of the disease are not well understood, and consequently, there are no proven steps that people can take to prevent it.Nonetheless（尽管如此）, some researchers have suggested that learning a foreign language might help delay the onset （发作）of dementia.

B) To explore this possibility more deeply, let's look at some of the common misconceptions （误解）about dementia and the aging brain.First of all, dementia is not an inevitable part of the normal aging process.Most older adults do not develop Alzheimer's disease or other forms of dementia.It is also important to remember that dementia（痴呆） is not the same thing as normal forgetfulness.At any age, we might experience difficulty finding the exact word we want or have trouble remembering the name of the person we just met.People with dementia have more serious problems, like feeling confused or getting lost in a familiar place.Think of it this way: If you forget where you parked your car at the mall（商场）, that's normal; if you forget how to drive a car, that may be a signal that something more serious is going on.

C)The idea that dementia can be prevented is based on the comparison of the brain to a muscle.

When people talk about the brain, they sometimes say things like "It is important to exercise your brain" or "To stay mentally fit（健康）, you have to give your brain a workout.（锻炼）"Although these are colorful analogies（类比）, in reality the brain is not a muscle.Unlike muscles, the brain is always active and works even during periods of rest and sleep.In addition, although some muscle cells have a lifespan（寿命） of only a few days, brain cells last a lifetime. Not only that, but it has been shown that new brain cells are being created throughout one's lifespan.

D) While it makes for a colorful analogy, comparing the brain to a muscle is inaccurate （不准确）and misleading. So, if the brain is not a muscle, can it still be exercised? Once again, researchers don't know for sure.There are now many computer, online, and mobile device applications that claim to be able to "train your brain," and they typically tap into a variety of cognitive abilities.

However, research suggests that although this type of training may improve one's abilities at the tasks themselves, they don't seem to improve other abilities.In other words, practicing a letter-detection task will, over time, improve your letter-detection skills, but it will not necessarily enhance your other perceptual （感知的）abilities.

E) However, there is some reason to believe that learning languages might be different.The best evidence that foreign language learning confers cognitive benefits comes from research with those who are already bilingual（双语言者）.Bilingualism most commonly occurs when children are exposed to two languages, either in the home (mom speaks Dutch（荷兰语）, dad speaks Spanish) or more formally in early schooling.But bilingualism certainly occurs in adulthood as well.

F) Bilingualism and multilingualism（多语言的） are actually more common than you might think.In fact, it has been estimated that there are fewer monolingual speakers in the world than bilinguals and multilinguals.Although in many countries most inhabitants（居民） share just one language, other countries have several official langu- ages.Switzerland, for example, has four official languages: German, French, Italian, and Romansh.Throughout large parts of Africa, Arabic, Swahili, French, and English are often known and used by individuals who speak a different, native language in their home than they do in the marketplace（市场）. So bilingualism and multilingualism are to be found throughout the world.And with regard to cognitive abilities, the research on those who speak more than one language paints an encouraging picture.（前景）

G) For one thing, bilinguals are better at multitasking.（多任务执行）One explanation of this superiority is that speakers of two languages are continually inhibiting （抑制）one of their languages, and this process of inhibition confers general cognitive benefits to other activities.In fact, bilingual individuals outperform their monolingual counterparts on a variety of cognitive tasks, such as following complex instructions, and switching to new instructions.For the sake of completeness, it should be noted that the advantages of being bilingual are not universal（普遍） across all cognitive domains.Bilingual individuals have been shown to have smaller vocabularies and to take longer in retrieving（检索） words from memory when compared to monolinguals（单语言）.In the long run, however, the cognitive and linguistic advantages of being bilingual far outweigh （更有价值）these two drawbacks. （缺点

H)If the benefits of being bilingual spill over to other aspects of cognition, then we would expect to see a lower incidence of Alzheimer's disease in bilinguals than in monolinguals, or at least a later onset of Alzheimer's for bilinguals.In fact, there is evidence to support this claim.The psychologist Ellen Bialystok and her colleagues obtained the histories of 184 individuals who had made use of a memory clinic in Toronto.For those who showed signs of dementia, the monolinguals in the sample had an average age of 71.4 years at the time of onset.The bilinguals, in contrast, received their diagnosis at 75.5 years, on average.In a study of this sort（类）, a difference of four years is highly significant, and could not be explained by other systematic differences between the two groups.For example, the monolinguals reported, on average, a year and a half more schooling than their bilingual counte- rparts, so the effect was clearly not due to formal education.

I) A separate study, conducted in India, found strikingly similar results: bilingual patients developed symptoms of dementia 4.5 years later than monolinguals, even after other potential factors, such as gender and occupation, were controlled for.In addition, researchers have reported other positive effects of bilingualism for cognitive abilities in later life,even when the person acquired the language in adulthood.Crucially, Bialystok suggested that the positive benefits of being bilingual were only found in those who used both languages all the time.

J)But encouraging as these kinds of studies are, they still have not established exactly how or why differences between bilinguals and monolinguals exist.Because these studies looked back at the histories of people who were already bilingual, the results can only say that a difference between the two groups was found, but not why that difference occurred.Further research is needed to determine what caused the differences in age of onset between the two groups.

K) Other studies of successful aging suggest that being connected to one's community and having plenty of social interaction is also important in delaying or even preventing the onset （发作）of dementia.Once again, however, the results are far less clear than the popular media might lead you to believe.Older individuals who lead active social lives are, almost by definition, healthier than their counterparts who rarely leave their homes or interact with others.So we can't really say whether being socially active prevents the onset of dementia, or if people who don't have dementia are more likely to be socially active.

L)

But even if studying a foreign language is not a magical cure-all（万能药）, there is one thing it will do: It will make you a better speaker of a foreign language.Doing that confers a whole host of advantages we do know about.

1.Research indicates that brain training is likely to boost one's ability at specific tasks, but not one's other cognitive abilities.

2.According to estimates, the number of people who speak two languages or more is greater than those who speak one language only.

3.For the time being, we do not know what causes people to lose their cognitive abilities, or what we can do to prev- ent it.

4.It is hard to determine whether people who are free from dementia tend to have more social activities, or more social activities keep people away from dementia.

5.There is evidence that learning foreign languages might be beneficial to boosting one's cognitive abilities.

6.It was suggested that only those who always spoke two languages could benefit from bilingualism.

7.The brain is different from muscles in that it keeps working even when the
