Irish Dolphins may have a unique dialect
Irish scientists monitoring dolphins living in a river estuary in the southwest of the c,ountry 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 vocalisations collected on a computer in a cowshed near the River Shannon．
As part of a research project．student Ronan Hickey digitised and analysed a total of 1，882 whisties from the Irish dolphins and those from the Welsh dolphins on a computer and separated them into six fundamental whistle types and 32 different eategories．0f the categories，he found most6 were used by both sets of dolphins一but eight were only heard from the Irish dolphins．
“We are building up a catalogue 0f the different whistle types they use and trying to associate them with behaviour like foraging，resting，socialising and the communications of groups with calves”project leader Simon Below said．“Essentially we are building up what is like a dictionary 0f words they use 0r sounds they make．”
Below，a nlan’ne biologist，said the dolphins’clicks are used t0 find their way around and locate prey．The whistles are communications．“They d0 a whole range 0f other sounds like barks，groans and a kind 0f gunshot．”he said．“The gunshot is an intense pulse of sound．Sperm whales use it t0 stun their prey．”
“When I first heard it 1 was surprised as I thought sperm whales were the only species who used it．We can speculate the dolphins are usin’g 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 generatl’ons and they may even have been resident there as far back as the 6th century9．
They are regularly seen by passengers 0n the Shannon ferry and an estimated 25，000 tourists every year take special sightseeing tours on local boats t0 visit them．
第 16 题 The difference in eating habits between the bottle-nose dolphins and the sperm whales interested the SDWF scientists．
A．Right
B．Wrong
C．Not mentioned

Cousteau Remembered
Jacques—Ives Cousteau died in Paris on 26 June，1997 at the age of 87．His influence is great． Scientists respected his creative engineering；engineers praised his science．Cousteau，who claimed to be neither scientist nor engineer，contributed significantly t0 both disciplines--and to many more．
Through out his adventure--filled 1ife，Cousteau challenged definitions．Yes，he was a captain in the French Navy，and early on，a filmmaker and natural storyteller．Later，he became a famous ocean explorer，designer of underwater equipment，expedition 1eader，author，speaker， businessman，environ- mentalist．teacher and leader of an influential organization（the Cousteau Society）．
All who care about the sea--and even those who don’t think much about the ocean one way or another--owe Cousteau a tremendous debt，The knowledge gained as a consequence 0f his direct contributions，and the strong others，have transformed the way the world thinks about the sea．His stories 0f encounters with sharks and 0ther fish inspired many t0 go see themselves．Cousteau pioneered ventures in underwater living in the l 960’s：sub-sea labs where scientists submerged for days or weeks．．．—the underwater labs similar to Skylab or the space station．His films and television programmes won two Academy Rewards，three Emnies，and the hearts and minds of Viewers worldwide for decades．
Showered with honours．Cousteau remarked recently that he thought his most important accomplishment was to make people aware of and care about—the ocean．Thanks to him．we grew concerned about our growing population and the consequences 0f overfishing and ocean pollution that threaten the health of the sea，and we were inspired to d0 something to improve the way things are done．
We shared the sad feeling with Cousteau when Simone，his wife and partner for many years，died and when his son Phillippe was killed in a plane crash．We shared his joy when Jean--Michael，his eldest son．became an explorer and a spokesman for the sea in his own right．We were happy for Cousteau when he began a new family with his second wife，Fracine．And now that his voice of the ocean is silenced，we feel very sad．
第 21 题 According to the passage，Cousteau’ s influence is great because he
A．was both a scientist and an engineer．
B．invented Skylab．
C．made contributions to science and engineering．
D．was a captain in the French Navy．

High Stress May Damage Memory
According to a report issued in May 1998，elderly people who have consistently high b1ood levels of cortisol don’t score as well on memory tests as their peels with lower levels of the stress hormone．What’s more． high 1evels of cortisol are also associated with shrinking 0f the hippocampus，a region of the brain that plays a key role in learning and memory．The 6ndings suggest that even cortisol levels in the normal，“healthy” range can actually accelerate brain aging．
The study results “now provide substantial evidence that long—term exposure to adrenal stress hormones may promote hippocampal aging in normal elderly humans，”write Nada Porter and Philip Landfield of the University of Kentucky in Lexington in their editorial．Cortisol is a hormone released in response to stress by the adrenal glands，which sit on top of the kidneys．
Over a 5 to 6一year period，Dr． Sonia Lupien and his colleagues measured 24一hour cortisol levels in 51 healthy volunteers，most of Whom were in their 70s．
Despite wide variation in cortisol levels．the participants could be divided into three Subgroups：those whose cortisol progressively increased over time and was currently high（increasing／high）：those whose cortisol progressively increased over time and was currently moderate（increasing／moderate）；and subjects whose cortisol decreased，but Was currently moderate（decreasing／moderate）．
The researchers tested the volunteers’ memory on six people in the increasing／high category and five people in the decreasing／moderate group．The groups did not differ on tests of immediate memory，but the increasing／high cortisol group had other memory problems compared with those in the decreasing／moderate group．
The researchers also found that the total volume of the hippocampus in those in the increasing／high group was 14％ lower than those in the decreasing／moderate group，although there were no differences in 0ther brain regions．
The results suggest that brain aging Can be accelerated by levels of adrenal hormones that are not generally regarded as pathological and that variation within this normal range is related to variation in the rate of brain aging．”write Porter and Landfield．“This further suggests that chronic stress may accelerate the worsening of hippocampus．”
第 26 题 The part of the brain important for a person’s learning and memory is．
A．the cortisol．
B．the adrenal glands．
C．the stress hormones
D．the hippocampus．

More about Alzheimer’s Disease
Scientists 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 disorder.
The only current means of diagnosing the disease in a living patient is a 1ong and expensive series of tests that eliminate every other cause of dementia.
“Since A1ois 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.”
A1zheimer，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 t0 function，and eventually causes death．There is currently no known treatment for the disease．
Researches discovered that the kin cells of Alzheimer’s patients have defects that interfere with their ability to regulate the now 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 deflects 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．
0ne test developed by researchers calls for growing skin cells in a laboratory calture and then testing them with an electrical detector to determine if the microscopic tunnels that govern the now 0f potassium are open． 0pen 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 he important rlevelopment，but tautioned that 0ther promising tests for Alzheimer’s have been disappointing．
第 46 题 The newly developed skin tests may be used in the future to allow doctors to
A．cure those with Alzheimer’s disease
B．discover the cause 0f Alzheimer’s disease
C．predict wh0 might get Alzheimer’s disease
D．find the consequences of A1zheimer’s disease
