Unit 4Section One Tactics for ListeningPart 1 Spot DictationStephen Powelson Amazing MemoryWhen Stephen Powelson was nine,his school organized a(1)weekly contest in memorizing passages from the Bible.Stephen paid(2)no attention until he was chided*for(3 not competing.The next Sunday he surprised everyone by(4)reciting all the passages for the(5)entire year.As a teenager in prep school,Stephen took Greek.His teacher(6)assigned 21 lines of the I liad*to be memorized(7)in a week.At the end of the hour-though he(8)insisted he paid full attention to the(9)lecture二 Stephen knew all 21.He went on to memorize the first(10)100 lines.I n 1978,for the first time(11)since college,Powelson,now 60,had some(12)spare time.To keep his mind active,he reread the I liad and(13)discovered that he still knew the first 100 lines(14)by heart.That someone could memorize so much between ages 60 and 70 is(15)astonishing to most people,who are(16)convinced that memory(17)worsens as we grow older.Powelsons method is to(18)read a book into his tape recorder,then read it several more times,making sure he understands(19)each word.Also,he says,I attempt to(20)visualize myself as part of the action.Part 2 Listening for GistYou might not know how rarely images are viewed directly through telescopes.The most common way to observe the skies is to photograph them.The process is very simple.First,a photographic plate is coated with a light-sensitive material.The plate is positioned so that the image received by the telescope is recorded on it.Then the image can be developed,enlarged,and published so that many people can study it Because most astronomical objects are very remote,the light we receive from them isfeeble.But by using a telescope as a camera,long time exposures can be made.I n this way,objects can be photographed that are a hundred times too faint to be seen by just looking through a telescope.ExerciseDirections:Listen to the dialogue and write down the gist and the key words that help you decide.1)This dialogue is about how to photograph astronomical objects.2)The key words are photograph,coated,light-sensitive material,positioned、received,recorded,developed,enlarged,published,remote,fbeble,telescope,camera,long exposures.Section Two Listening ComprehensionPart one DialogueTunisian Holiday(Someone is

southwest.2)The program is now about halfway to meeting its goal of a wild population of at least 100 wolves covering more than 12,800 square kilometers.3)Decisions about mating,movement among the 45 captive-breeding facilities and releases into the wild are made by a US-Mexican committee of scientists,landowners and others.4)A wolf with rare genes-until it has successfully reproduced-will never be released because of the high mortality rate in the wild.5)The recovery program is gradually moving away from freeing captive-bornwolves,as the population of pups born free takes off.Francisco and Sheila were pioneers in a federal program in Eureka,32 kilometers southwest of St.Louis,the United States,to restore the endangered Mexican gray wol the rarest and most genetically distinct subspecies of gray wolf in North America.After more than a century of assault（攻击，袭击）by humans,the wolf population had dwindled to（减少到）no more than a handful by the 1970s in Mexico and the American southwest.The research center,popularly known as the Wolf Sanctuary*,was founded in 1971 by Marlin Perkins,a world-renowned（世界知名的）naturalist and former director of the St.Louis Zoo,and his wife Carol.Besides the Mexican wol the sanctuary works with the endangered red wolf（赤狼）,maned wolf（鬃狼）,swift fox（草原狐）/and African wild dogs（豺狗）.I n the late 1970s,the last seven known wolves were captured in the wild or taken from zoos to begin the breeding program（育种计划）.I n 1981,the first captive-bred（人工繁殖的，圈养的）litter（幼狼）of Mexican gray wolves produced in the federal program was born at the Wild Canid Center,and the first release into the wild（放生）took place in 1998.The program is now about halfway to meeting its goal of a wild population of at least 100 wolves covering more than 12,800 square kilometers.Though in captivity（在繁殖场）themselves,Francisco and Sheila taught their pups so well that many are thriving in the wild.They were ideal parents.They raised 25 babies,taught them good survival skills and sent many of them off to live on their own.Nine of Francisco and Sheilas offspring were among the first 11 captive-bomMexican gray wolves released in 1998.Both parent wolves have since died-Francisco at age 14 in December.Sheila at age 16 in June 2000-but they lived,as captive wolves often do,roughly twice as long as wolves in the wild.Today the Wild Canid Survival and Research Center in Eureka estimates that 98 percent of Mexican wolves released from the federal program are descendants of the prolific*lobo*pair.About 250 lobos now live in captivity at 45 US and Mexican facilities.The Wild Canid Center,however,has produced more puppies and housed more Mexican grays than any other facility.The Wild Canid Center is ideated*on 25 isolated hectares within Washington Universitys Tyson Research Center.The wolves live in large outdoor enclosures with minimal human contact.They learn to hunt,raise young,live in natural family packs,and to be suspicious of people-all necessary skills for surviving in the wild.Decisions about mating,movement among the 45 captive-breeding facilities and releases into the wild are made by a US-Mexican committee of scientists,landowners and others.They also maintain a genetic database.A wolf with rare genes-until it has successfully reproduced-will never be released because of the high mortality rate（死亡率）in the wild.I ts not uncommon for freed wolves to be struck by cars or shot by hunters;in recent weeks,five have died.Despite the losses,released wolves are reproducing.The recovery program is gradually moving away from freeing captive-born wolves,as the population of pups born free takes off(增力口).Scientists want to let nature decide whats a good wolf and whats not through natural selection.A:Pre-listening QuestionThe wolf is a large member of the canine family.Most of the adult grey wolves weigh in the vicinity of 75 to 125 pounds(34 to 56 kilograms).Wolves live in family groups called packs.A pack is usually made up of a male parent,a female parent,their pups and a few other adult wolves that are the older brothers and sisters.Wolves can run up to 40 miles an hour and can easily cover 50 miles a day.The wolf has developed the capacity to survive in the most inhospitable of climatesThe wolves in the high arctic endure several winter months of perpetual darkness.Even in February when the sun returns to the north,temperatures of-40 and bitter winds are common.I n the wild wolves can live up to 13 years or more;in a protected wolf park or a controlled area of land,a wolf can live to be up to 16 years old.B:Sentence DictationDirections:Listen to some sentences and write them down.You will hear each sentence three times.C:Detailed Listening1 Directions:Listen to the passage and complete the
