Irish Dolphins May Have a Unique Dialect
Irish scientists monitoring dolphins living in a river estuary in the southwest of the country believe they
may have developed a unique dialect to communicate with each other.
The Shannon Dolphin and Wildlife Foundation(SDWF)has been studying a group of up to 120 bottle-
nose dolphins in the River Shannon using vocalizations（发声）collected on a computer in a cow shed near the
River Shannon.
As part of a research project,student Ronan Hickey digitized and analyzed a total of 1,882 whistles from
the Irish dolphins and those from the Welsh dolphins on a computer and separated theni into six fundamental
whistle types and 32 different categories.Of the categories,he found most were used by both sets of dol-
phins一but eight were only heard from the Irish dolphins.
"We are building up a catalogue of the different whistle types they use and trying to associate them with
behavior like foraging（觅食）,resting, socializing and the communications of grown.ups with calves (幼
仔）,"project leader Simon Berrow said.“Essentially we are building up what is like a dictionary of words
they use or sounds they mnake."
Berrow,a marine biologist,said the dolphins'clicks are used to find their way around and locate prey.
The whistles are communications."They do a whole range 0f other sounds like barks．groans and a kind of
gunshot," he said. "The gunshot is an intense pulse（脉冲）of sound. Sperm whales use it to stun（击昏）
their prey.”
"When I first heard it I was surprised as I thought sperm whales were the onlyh species who used it. We
can speculate the dolphins are using it for the same reason as the sperm whales,"Berrow said.
References in local legend indicate there have been dolphins in the Shannon estuary for generations and
they may even have been residents there as far back as the 6th century.
They are regularly seen by passengers on the Shannon ferry and an estimated 25.000 tourists every year
take special sightseeing tours on local boats to visit them.

参考答案
参考解析
解析：利用题干句的特征词sperm whales作为线索，发现文中第5、6两段与其相关。但是相 关的语句中都没有涉及题干句中关于饮食习惯差异的内容，因此判断题干句的内容在文章中 没有被提到。
利用题干句的特征词32 categorie、和eight作为线索，找到相关句“…32 different catego-ries.Of the categories,he found most were used by both sets of dolphins一but eight were only heard from the Irish dolphins.”这与题干句意思一致，故选A。
利用题干句的特征词communicate、 adult和baby为线索，找到相关句“…of the different whistle types…to aggociate them with behavior like…and the communicationg of grown-ups with calves"，这是说科学家正在设法将哨声与海豚的行为联系起来，如成年海豚用它来与小海豚进 行沟通。题干句的意思与原文的意思相符，所以答案是A。
利用题干句的特征词Simon Berrow和dictionary为线索，找到相关句“…Simon Berrow said,'…we are building up what jg like a dictionary of wordc they uce or g ound、 they make'”,；坟 与题干句意思完全吻合，所以选A。
利用题干句的特征词pulses of sound为线索，查找原文，找到“The gunshot is an intense pulse（脉冲）of sound.Sperm whales use it to stun their prey.”。但是是不是只有抹香鲸会用脉冲 呢？继续看下文，发现下一段说海豚也会用，所以题干句的内容不正确：
利用6th century这个特征词在原文中可以找到相关信息，在倒数第2段，意为“……早 在公元6世纪，海豚就在香农河河口繁衍生息”，而不是“被渔民养殖”，所以答案是B
利用特征词25,000为线索，查找原文，找到“…an estimated 25 , 000 tourists every year take special sightseeing tours on local boats to visit them."；还需要确定该句中的they是否指代 Irish dolphins，借助前句内容知道they指代Shannon河口的海豚，由文章开头两段可知River Shannon是爱尔兰的河流，所以答案是A。第3部分：概括大意与完成句子
利用题干句的特征词32 categorie、和eight作为线索，找到相关句“…32 different catego-ries.Of the categories,he found most were used by both sets of dolphins一but eight were only heard from the Irish dolphins.”这与题干句意思一致，故选A。

Adaptation of Living ThingsCertain animals and plants develop characteristics that help them cope with their environment better than others of their kind.This natural biological process is called adaptation.Among the superior characteristics developed through adaptationare those that may help in getting food or shelter,in providing protection,and in producing and protecting the young.That results in the evolution of more and more organisms（微生物）that are better fitted to their environments.Each living thing is adapted to its way of life in a general way,but each is adapted especially to its own distinct class.A plant,for example,depends upon its roots to fix itself firmly and to absorb water and inorganic（无机的）chemicals.It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals.These are general adaptations,common to most plants.In addition,there are special adaptations that only certain kinds of plants have.Many animals have adaptations that help them escape from their enemies.Some insects are hidden by their body color or shape,and many look like a leaf or a little branch.The coats of deer are colored to mix with the surroundings.Many animals have the ability to remain completely still when an enemy is near.Organisms have a great variety of ways of adapting.They may adapt.in their structure,function,and genetics;in their development and production of the young;and in other respects.An organism may create its own environment,as do warm-blooded mammals（哺乳动物）,which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather.Usually adaptations are an advantage,but sometimes an organism is so well adapted to a particular environment that,if conditions change,it finds it difficult or impossible to readapt to the new conditions.The author cites the behavior of warm-blooded mammals in order to illustrate that______.A:a living thing may have the ability to create an environment of its ownB:a living creature may have the ability to remain still when an enemy is nearC:a living creature may have the ability to make food from its inorganic chemicalsD:a living creature may have the ability to change the color of its skin

第一篇More About Alzheimer' s DiseaseScientists have developed skin tests that may be used in the future to identify people with Alzheimer's disease and may ultimately allow physicians to predict who is at risk of getting this neurological （神经病学的）disorder.The only current means of diagnosing the disease in a living patient is a long and expensive series of tests that eliminate every other cause of dementia."Since Alois Alzheimer described the disease nearly a century ago,people have been trying to find a way to accurately diagnose it in its early stages,"said Patricia Grady,acting director of the National Institute of Neurological Disorders and Stroke in Bethesda,Maryland."This discovery,if confirmed,could prove a big step forward in our efforts to deal with and understand the disease."Alzheimer's is the single greatest cause of mental deterioration in older people,affecting between 2.5 million and 4 million people in the United States alone.The devastating disorder gradually destroys memory and the ability to function,and eventually causes death. There is currently no known treatment for the disease.Researchers discovered that the skin cells of Alzheimer's patients have defects that interfere with their ability to regulate the flow of potassium in and out of the cells.The fact that the cell defects are present in the skin suggests that Alzheimer's results from physiological changes throughout the body,and that dementia may be the first noticeable effect of these changes as the defects affect the cells in the brain,scientists said.The flow of potassium is especially critical in cells responsible for memory formation.The scientists also found two other defects that affect the cells' supply of calcium,another critical element.One test developed by researches calls for growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that govern the flow of potassium are open.Open potassium channels create a unique electrical signature.A spokesman for the Alzheimer's Association said that if the validity of the diagnostic test can be proven it would be an important development,but he cautioned that other promising tests for Alzheimer's have been disappointing.The last paragraph implies that the diagnostic test________.A:will not be as promising as othersB:is a very important developmentC:may not be proven valid smoothlyD:will surely be disappointing in the end

Natural MedicinesSince earliest days,humans have used some kinds of medicines.We know this because humans have survived.Ancient treatments for injury and disease were successful enough to keep humans from dying out completely.They were successful long before the time of modern medicine. Before the time of doctors with white coats and shiny（发亮的）instruments. Before the time of big hospitals with strange and wonderful equipment.Many parts of the world still do not have university-educated doctors. Nor do they have expensive hospitals.Yet injuries are treated.And diseases are often cured.How?By ancient methods. By medicines that might seem mysterious , even magical（有魔力的）.Traditional medicines are neither mysterious nor magical,however.Through the centuries , tribal（部落的）medicine men experimented with plants. They found many useful chemicals in the plants.And scientists believe many of these traditional medicines may provide the cure for some of today's most serious diseases.Experts say almost 80% of the people in the world use plants for health care.These natural medicines are used not just because people have no other form of treatment. They are used because people trust them. In developed areas,few people think about the source of the medicines they buy in a store .Yet many widely-used medicines are from ancient sources,especially plants.Some experts say more than 25%of modem medicines come,in one way or another,from nature.Scientists have long known that nature is really a chemical factory. All living things contain chemicals that help them survive .So scientists' interest in traditional medicine is not new.But it has become an urgent concern.This is because the earth's supply of natural medicines may be dropping rapidly. It can be seen from the passage that the earth's supply of natural medicines______.A: may never be exhaustedB: may be dropping rapidlyC: is surprisingly bigD: is as rich as ever

Irish Dolphins May Have a Unique DialectIrish scientists monitoring dolphins living in a river estuary in the southwest of the country believe they may have developed a unique dialect to communicate with each other.The Shannon Dolphin and Wildlife Foundation(SDWF)has been studying a group of up to 120 bottle- nose dolphins in the River Shannon using vocalizations（发声）collected on a computer in a cow shed near the River Shannon.As part of a research project,student Ronan Hickey digitized and analyzed a total of 1,882 whistles from the Irish dolphins and those from the Welsh dolphins on a computer and separated theni into six fundamental whistle types and 32 different categories.Of the categories,he found most were used by both sets of dol-phins一but eight were only heard from the Irish dolphins."We are building up a catalogue of the different whistle types they use and trying to associate them withbehavior like foraging（觅食）,resting, socializing and the communications of grown.ups with calves (幼 仔）,"project leader Simon Berrow said.“Essentially we are building up what is like a dictionary of wordsthey use or sounds they mnake."Berrow,a marine biologist,said the dolphins'clicks are used to find their way around and locate prey.The whistles are communications."They do a whole range 0f other sounds like barks．groans and a kind of gunshot," he said. "The gunshot is an intense pulse（脉冲）of sound. Sperm whales use it to stun（击昏）their prey.”"When I first heard it I was surprised as I thought sperm whales were the onlyh species who used it. Wecan speculate the dolphins are using it for the same reason as the sperm whales,"Berrow said.References in local legend indicate there have been dolphins in the Shannon estuary for generations and they may even have been residents there as far back as the 6th century.They are regularly seen by passengers on the Shannon ferry and an estimated 25.000 tourists every year take special sightseeing tours on local boats to visit them.Of the 32 categories,eight were produced only by the Irish dolphins.A:RightB:WrongC:Not mentioned
