READING COMPREHENSIONPART II READING COMPREHENSION (30 MIN)Directions: In this section there are four reading passages followed by a total of 20 multiple-choice questions. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Britain’s east midlands were once the picture of English countryside, alive with flocks, shepherds, skylarks and buttercups—the stuff of fairytales. In 1941 George Marsh left school at the age of 14 to work as a herdsman in Nottinghamshire, the East Midlands countryside his parents and grandparents farmed. He recalls skylarks nesting in cereal fields, which when accidentally disturbed would fly singing into the sky. But in his lifetime, Marsh has seen the color and diversity of his native land fade. Farmers used to grow about a ton of wheat per acre; now they grow four tons. Pesticides have killed off the insects upon which skylarks fed, and year-round harvesting has driven the birds from their winter nests. Skylarks are now rare. “Farmers kill anything that affects production,”says Marsh. “Agriculture is too efficient. “Anecdotal evidence of a looming crisis in biodiversity is now being reinforced by science. In their comprehensive surveys of plants, butterflies and birds over the past 20 to 40 years in Britain, ecologists Jeremy Thomas and Carly Stevens found significant population declines in a third of all native species. Butterflies are the furthest along—71 percent of Britain’s 58 species are shrinking in number, and some, like the large blue and tortoiseshell, are already extinct. In Britain’s grasslands, a key habitat, 20 percent of all animal, plant and insect species are on the path to extinction. There’s hardly a corner of the country’s ecology that isn’t affected by this downward spiral. The problem would be bad enough if it were merely local, but it’s not : because Britain’s temperate ecology is similar to that in so many other parts of the world, it’s the best microcosm scientists have been able to study in detail. Scientists have sounded alarms about species’extinction in the past, but always specific to a particular animal or place—whales in the 1980s or the Amazonian rain forests in the 1990s. This time, though, the implications are much wider. The Amazon is a “biodiversity hot spot”with a unique ecology. But in Britain, “the main drivers of change are the same processes responsible for species’declines worldwide, “says Thomas. The findings, published in the journal Science, provide the first clear evidence that the world is in the throes of a massive extinction. Thomas and Stevens argue that we are facing a loss of 65 to 95 percent of the world’s species, on the scale of an ice age or the meteorite that may have wiped out the dinosaurs 65 million years ago. If so, this would be only the sixth time such devastation had occurred in the past 600 million years. The other five were associated with one-off events like the ice ages, a volcanic eruption or a meteor. This time, ecosystems are dying a thousanddeaths—from overfishing and the razing of the rain forests, but also from advances in agriculture. The British study, for instance, finds that one of the biggest problems is nitrogen pollution. Nitrogen is released when fossil fuels burn in cars and power plants—but also when ecologically rich heath-lands are plowed and fertilizers are spread. Nitrogen-rich fertilizers fuel the growth of tall grasses, which in turn overshadow and kill off delicate flowers like harebells and eyebrights. Even seemingly innocuous practices are responsible for vast ecological damage. When British farmers stopped feeding horses and cattle with hay and switched to silage, a kind of preserved short grass, they eliminated a favorite nesting spot of corncrakes, birds known for their raspy nightly mating calls; corncrake populations have fallen 76 percent in the past 20 years. The depressing list goes on and on. Many of these practices are being repeated throughout the world, in one form or another, which is why scientists believe that the British study has global implications. Wildlife is getting blander. “We don’t know which species are essential to the web of life so we’re taking a massive risk by eliminating any of them,” says David Wedin, professor of ecology at the University of Nebraska. Chances are we’ll be seeing the results of this experiment before too long.1．From the first paragraph, we get the impression that George MarshA．cherishes his adolescence memories.B．thinks highly of the efficiency of agriculture.C．may not have happy memories of past time.D．cannot remember his adolescence days.正确答案：A解析：推断题。

以下是店铺为大家搜索整理的英语专八中级阅读练习及答案解析，希望对正在关注的您有所帮助!Passage Nineteen (Creative Process of Works)The great question that this paper will, but feebly, attempt to answer is , what is the creative process?Though much theory has accumulated, little is really known about the power that lies at the bottom of poetic creation.It is true that great poets and artists produce beauty by employing all the powers of personality and by fusing emotions, reason, and intuitions.But what is the magical synthesis that joins and arranges these complex parts into poetic unity?John L.Lowes, in his justly famous “The Road to Xanadu,” developed one of the earliest and still generally acceptable answers to this tantalizing question.Imaginative creation, he concludes, is a complex process in which the conscious and unconscious minds jointly operate.“There is…the deep well with its chaos of fortuitously blending images; but there is likewise the Vision which sees shining in and through the chaos of the potential lines of Form, and with the Vision, the controlling Will.Which gives to that potential beauty actuality.”The Deep Well is the unconscious mind that is peopled with the facts, ideas, feelings of the conscious activity.The imaginative vision, an unconscious activity, shines through the land of chaos, of lights and shadows, silently seeking pattern and form.Finally, the conscious mind again, through Will, captures and embodies the idea in the final work of art.In this way is unity born out of chaos.Though there can be no absolute certainty, there is general agreement that the periods in the development of a creative work parallel, to some extent, Lowes’ theory of Well,Vision, Form, and Will.There are at least three stages in the creative process: preparation, inspiration, work.In a sense, the period of preparation is all of the writer’s life.It is the Deep Well.It is the Deep Well.It is especially a period of concentration which gives the unconscious mind an opportunity to communicate with the conscious mind.When remembrance of things past reach the conscious level of the writer’s mind, he is ready to go on with the process.Part of this preparation involves learning a medium—learning a language, learning how to write, learning literary forms.It is important to mot here that form cannot be imposed upon the idea.Evidence, though sparse, shows that the idea gives birth to the form that can best convey it.It is the Vision, according to Lowes, ” which sees shining in and through the chaws of the potential lines of from … ”1.When remembrance of things past reach the conscious level, the post has reached the stage called ___________[A]Well.[B]Vision.[C]Form.[D]Will.2.Which of the following statements is TRUE?[A]The form determines the subject matter.[B]The idea determines the form.[C]Vision makes beauty an actuality.[D]A writer is unconscious when he prepares his work.3.The word “fortuitously” in the third paragraph means___________[A]accidentally.[B]luckily.[C]thoroughly.[D]potentially.4.The remembrance of things past is carried on in the ___________[A]Deep Well.[B]Vision.[C]Chaotic lights and shadows.[D]Conscious mind.Vocabulary1.fuse 融化，结合2.intuition 直觉3.Xanadu 是一个非常美的，田园诗般的地方。
英语专八阅读理解练习附答案
英语专八阅读理解练习附答案英语专八阅读理解练习附答案篇一Racket, din clamor, noise, whatever you want to call it, unwanted sound is America’s most widespread nuisance. But noise is more than just a nuisance. It constitutes a real and present danger topeople’s health. Day and night, at home, at work, and at play, noise can produce serious physical and psychological stress. No one is immune to this stress. Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes and the body still responds—sometimes with extreme tension, as to a strange sound in the night. The annoyance we feel when faced with noise is the most common outward symptom of the stress building up inside→← us. Indeed, because irritability is so apparent, legislators have made public annoyance the basis of many noise abatement programs. The more subtle and more serious health hazards associated with stress caused by noise traditionally have been given much less attention. Nevertheless, when we are annoyed or made irritable by noise, we should consider these symptoms fair warning that other thing may be happening to us, some of which may be damaging to our health.Of many health hazards to noise, hearing loss is the most clearly observable and measurable by health professionals. The other hazards are harder to pin down. For many of us, there may be a risk that exposure to the stress of noise increases susceptibility to disease and infection. The more susceptible among us may experience noise as a complicating factor in heart problems and other diseases. Noisethat causes annoyance and irritability in health persons may have serious consequences for these already ill in mind or body.Noise affects us throughout our lives. For example, there areindications of effects on the unborn child when mothers are exposedto industrial and environmental noise. During infancy and childhood, youngsters exposed to high noise levels may have trouble falling asleep and obtaining necessary amounts of rest.Why, then, is there not greater alarm about these dangers? Perhaps it is because the link between noise and many disabilities or diseases has not yet been conclusively demonstrated. Perhaps it is because we tend to dismiss annoyance as a price to pay for living in the modern world. It may also be because we still think of hearing loss as only an occupational hazard.1.In Paragraph 1, the phrase immune to are used to mean ___.A.unaffected byB.hurt byC.unlikely to be seen byD.unknown by2.The author’s attitude toward noise would best be described as ___.A.unrealisticB.traditionalC.concernedD.hysterical3.Which of the following best states the main idea of the passage?A.Noise is a major problem; most people recognize its importance.B.Although noise can be annoying, it is not a major problem.C.Noise is a major problem and has not yet been recognized as such.D.Noise is a major problem about which nothing can be done.4.The author condemns noise essentially because it ___.A.is against the lawB.can make some people irritableC.is a nuisanceD.in a ganger to people’s health5.The author would probably consider research about the effects noise has on people to be ___.possible.C.a waste of moneyD.essential答案：ACCDD英语专八阅读理解练习附答案篇二Joy and sadness are experienced by people in all cultures around the world, but how can we tell when other people are happy or despondent? It turns out that the expression of many emotions may be universal. Smiling is apparently a universal sign of friendliness and approval. Baring the teeth in a hostile way, asnoted by Charles Darwin in the nineteenth century, may be a universe sign of anger. As the originator of the theory of evolution, Darwin believed that the universal recognition of facial expressions would have survival value. For example, facial expressions could signal the approach of enemies (or friends) in the absence of language.Most investigators concur that certain facial expressions suggest the same emotions in a people. Moreover, people in diverse cultures recognize the emotions manifested by the facial expressions. In classic research Paul Ekman took photographs of people exhibiting the emotions of anger, disgust, fear, happiness, and sadness. He then asked people around the world to indicate what emotions were being depicted in them. Those queried ranged from European college studentsto members of the Fore, a tribe that dwells in the New Guinea highlands. All groups including the Fore, who had almost no contact with Western culture, agreed on the portrayed emotions. The Fore also displayed familiar facial expressions when asked how they would respond if they were the characters in stories that called for basic emotional responses. Ekman and his colleagues morerecently obtained similar results in a study of ten cultures in which participants were permitted to report that multiple emotions were shown by facial expressions. The participants generally agreed on which two emotions were being shown and which emotion was more intense.Psychological researchers generally recognize that facial expressions reflect emotional states. Infact, various emotional states give rise to certain patterns of electrical activity in the facial muscles and in the brain. The facial-feedback hypothesis argues, however, that the causal relationship between emotions and facial expressions can also work in the opposite direction. According to this hypothesis, signals from the facial muscles ("feedback") are sent back to emotion centers of the brain, and so a person's facial expression can influence that person's emotional state.ConsiderDarwin's words: "The free expression by outward signs of an emotion intensifies it. On the otherhand, the repression, as far as possible, of all outward signs softens our emotions." Can smiling giverise to feelings of good will, for example, and frowning to anger?Psychological research has given rise to some interestingfindings concerning the facial-feedback hypothesis. Causing participants in experiments to smile, for example, leads them to report morepositive feelings and to rate cartoons (humorous drawingsof people or situations) as being morehumorous. When they are caused to frown, they rate cartoons as being more aggressive.What are the possible links between facial expressions and emotion? One link is arousal, which is the level of activity or preparedness for activity in an organism. Intense contraction of facial muscles,such as those used in signifying fear, heightens arousal. Self-perception of heightened arousal then leads to heightened emotional activity. Other links may involve changes in brain temperature and the release of neurotransmitters (substances that transmit nerve impulses.) The contraction of facial muscles both influences the internal emotional state and reflects it. Ekman has found that theso-called Duchenne smile, which is characterized by "crow's feet" wrinkles around the eyes and asubtle drop in the eye cover fold so that the skin above the eye moves down slightly toward theeyeball, can lead to pleasant feelings.Ekman's observation may be relevant to the British expression "keep a stiff upper lip" as are commendation for handling stress. It might be that a "stiff" lip suppresses emotional response-as long as the lip is not quivering with fear or tension. But when the emotion that leads to stiffening the lip is more intense, and involves strong muscle tension, facial feedback may heighten emotional response.1. The word despondent in the passage is closest in meaning toA curiousB unhappyC thoughtfulD uncertain2. The author mentions "Baring the teeth in a hostile way" in order toA differentiate one possible meaning of a particular facial expression from other meanings of itB upport Darwin's theory of evolutionC provide an example of a facial expression whose meaning is widely understoodD contrast a facial expression that is easily understood with other facial expressions3. The word concur in the passage is closest in meaning toA estimateB agreeC expectD understand4. According to paragraph 2, which of the following was true of the Fore people ofNew Guinea?A They did not want to be shown photographs.B They were famous for their story-telling skills.C They knew very little about Western culture.D They did not encourage the expression of emotions.5. According to the passage, what did Darwin believe would happen to human emotions that werenot expressed?A They would become less intense.B They would last longer than usual.C They would cause problems later.D They would become more negative.参考答案：B C B C A。

Consider Pasteur, he discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available.”This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2000, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging -- 13 percent for lung cancer, and 2 percent for cancer of the pancreas.With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes, are inactive in normal cells. Anything from cosmic rays to radiation to diet may activate a dormant oncogene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous.The exact mechanisms involved are still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. “Changes are a normal part of the evolutionary process,” says oncologist William Hayward. Environmental factors can never be totallyeliminated; as Hayward points out, “We can’t prepare a medici ne against cosmic rays.”The prospects for cure, though still distant, are brighter.“First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells which are always responsible for at least part of the trouble. If we can understand how cancer works, we can counteract its action.”习题1.The example of Pasteur in the passage is used to ________.[A] predict that the secret of cancer will be disclosed in a decade[B] indicate that the prospects for curing cancer are bright[C] prove that cancer will be cured in fifty to sixty years[D] warn that there is still a long way to go before cancer can be conquered2. The author implies that by the year 2000, ________.[A] there will be a drastic rise in the five-year survival rate of skin-cancer patients[B] 90 percent of the skin-cancer patients today will still be living[C] the survival statistics will be fairly even among patients with various cancers[D] there won’ t be a drastic increase of survival rate of all cancer patients3. Oncogenes are cancer-causing genes ________.[A] that are always in operation in a healthy person[B] which remain unharmful so long as they are not activated[C] that can be driven out of normal cells[D] which normal cells can’t turn off4. The word “dormant” in the third paragraph most probably means ________.[A] dead[B] ever-present[C] inactive[D] potential全文翻译“我有极大的信心相信到这个十年期结束时我们将会详尽地知晓癌细胞的生成原因，”一位癌症专家和微生物学家罗伯特•温伯格说道。

以下是店铺为大家搜索整理的英语专业八级阅读考试训练试题附答案，希望能给大家带来帮助!He was an old man with a white beard and huge nose and hands. Long before the time during which we will know him, he was a doctor and drove a jaded white horse from house to house through the streets of Winesburg. Later he married a girl who had money. She had been left a large fertile farm when her father died. The girl was quiet, tall, and dark, and to many people she seemed very beautiful. Everyone in Winesburg wondered why she married the doctor. Within a year after the marriage she died.The knuckles of the doctor's hands were extraordinarily large. When the hands were closed they looked like clusters of unpainted wooden balls as large as walnuts fastened together by steel rods. He smoked a cob pipe and after his wife's death sat all day in his empty office close by a window that was covered with cobwebs. He never opened the window. Once on a hot day in August he tried but found it stuck fast and after that he forgot all about it.Winesburg had forgotten the old man, but in Doctor Reefy there were the seeds of something very fine. Alone in his musty office in the Heffner Block above the Paris Dry Goods Company's store, he worked ceaselessly, building up something that he himself destroyed. Little pyramids of truth he erected and after erecting knocked them down again that he might have the truths to erect other pyramids.Doctor Reefy was a tall man who had worn one suit of clothesfor ten years. It was frayed at the sleeves and little holes had appeared at the knees and elbows. In the office he wore also a linen duster with huge pockets into which he continually stuffed scraps of paper. After some weeks the scraps of paper became little hard round balls, and when the pockets were filled he dumped them out upon the floor. For ten years he had but one friend, another old man named John Spaniard who owned a tree nursery. Sometimes, in a playful mood, old Doctor Reefy took from his pockets a handful of the paper balls and threw them at the nursery man. "'That is to confound you, you blithering old sentimentalist," he cried, shaking with laughter.The story of Doctor Reefy and his courtship of the tall dark girl who became his wife and left her money to him is a very curious story. It is delicious, like the twisted little apples that grow in the orchards of Winesburg. In the fall one walks in the orchards and the ground is hard with frost underfoot. The apples have been taken from the trees by the pickers. They have been put in barrels and shipped to the cities where they will be eaten in apartments that are filled with books, magazines, furniture, and people. On the trees are only a few gnarled apples that the pickers have rejected. They look like the knuckles of Doctor Reefy’ s hands. One nibbles at them and they are delicious. Into a little round place at the side of the apple has been gathered all of its sweetness. One runs from tree to tree over the frosted ground picking the gnarled, twisted apples and filling his pockets with them. Only the few know the sweetness of the twisted apples.The girl and Doctor Reefy began their courtship on a summer afternoon. He was forty-five then and already he had begun the practice of filling his pockets with the scraps of paper that became hard balls and were thrown away. The habit had beenformed as he sat in his buggy behind the jaded grey horse and went slowly along country roads. On the papers were written thoughts, ends of thoughts, beginnings of thoughts.One by one the mind of Doctor Reefy had made the thoughts. Out of many of them he formed a truth that arose gigantic in his mind. The truth clouded the world. It became terrible and then faded away and the little thoughts began again.The tall dark girl came to see Doctor Reefy because she was in the family way and had become frightened. She was in that condition because of a series of circumstances also curious.The death of her father and mother and the rich acres of land that had come down to her had set a train of suitors on her heels. For two years she saw suitors almost every evening. Except two they were all alike. They talked to her of passion and there was a strained eager quality in their voices and in their eyes when they looked at her. The two who were different were much unlike each other. One of them, a slender young man with white hands, the son of a jeweler in Winesburg, talked continually of virginity. When he was with her he was never off the subject. The other, a black-haired boy with large ears, said nothing at all but always managed to get her into the darkness, where he began to kiss her.For a time the tall dark girl thought she would marry the jeweler's son. For hours she sat in silence listening as he talked to her and then she began to be afraid of something. Beneath his talk of virginity she began to think there was a lust greater than in all the others. At times it seemed to her that as he talked he was holding her body in his hands. She imagined him turning it slowly about in the white hands and staring at it. At night she dreamed that he had bitten into her body and that his jaws weredripping. She had the dream three times, then she became in the family way to the one who said nothing at all but who in the moment of his passion actually did bite her shoulder so that for days the marks of his teeth showed...-..-.After the tall dark girl came to know Doctor Reefy it seemed to her that she never wanted to leave him again. She went into his office one morning and without her saying anything he seemed to know what had happened to her.In the office of the doctor there was a woman, the wife of the man who kept the bookstore in Winesburg. Like all old-fashioned country practitioners, Doctor Reefy pulled teeth, and the woman who waited held a handkerchief to her teeth and groaned. Her husband was with her and when the tooth was taken out they both screamed and blood ran down on the woman's white dress. The tall dark girl did not pay any attention. When the woman and the man had gone the doctor smiled. "I will take you driving into the country with me," he said.For several weeks the tall dark girl and the doctor were together almost every day. The condition that had brought her to him passed in an illness, but she was like one who has discovered the sweetness of the twisted apples, she could not get her mind fixed again upon the round perfect fruit that is eaten in the city apartments. In the fall after the beginning of her acquaintanceship with him she married Doctor Reefy and in the following spring she died. During the winter he read to her all of the odds and ends of thoughts he had scribbled on the bits of paper. After he had read them he laughed and stuffed them away in his pockets to become round hard balls.1.According to the story Doctor Reefy’s life seems very __________.A. eccentricB. normalC. enjoyableD. optimistic2.The story tells us that the tall dark girl was in the family way. The phrase “in the family way” means____________.A. troubledB. PregnantC. twistedD. cheated3.Doctor Reef lives a ___________ life.A. happyB. miserableC. easy-goingD. reckless4. The tall dark girl’s marriage to Doctor Reef proves to bea _____ one.A. transientB. understandableC. perfectD. funny5.

In New York, as much as in most communities in America, basketball is a more religious rite than sport.(2)Kids are at the playground as long as ten hours a day, actually playing as early as six.(3)Seventeen-and eighteen-olds already have rheumatoid knees from the constant pounding of their feet on the hard road. (4)They play in the heat of the afternoon with not much more to fuel them than a can of soda and a store-bought pastry, and they play at night in the dim illumination of nearby street lights and flashing neon.(5) In a single summer, typical city ballplayers will wear out four or five pairs of sneakers.(6)They play even in the dead of winter, bundled in jackets and sweaters and belching up little puffs of steam, as they bang away at the net’s rims.This type of instrument is called meteorologica l balloon, which is used to measure the wind speed and direction in the sky.The study of primitive peoples has discovered such a diversity of customs, values, feelings, and thoughts that many anthropologists arrived at the concept that man is born as a blank sheet of paper on which each culture writers its text.Example: (05’)When former President Ronald Reagan fell and broke his hip at the age of 89 , he joined a group of more than 350,000 elderly Americans who fracture their hips each year. Suffering from advanced Alzheimer's disease, Reagan is in one of the highest-risk groups for this type of accident. The incidence of hip fractures not only increases after age 50 but doubles every five to six years as the risk of falling increases. Slipping and tumbling are not the only causes of hip fractures; weakened bones sometimes break spontaneously. But falling is the major cause, representing 90% of all hip fractures.These injuries are not to be taken lightly. According to the American Academy of Orthopedic Surgeons, only 25% of those who suffer hip fractures ever fully recover; as many as 20% will die within 12 months. Even when patients do recover, nearly half will need a cane or a walker to get around.When it comes to hip fractures, the most dangerous place for elderly Americans, it turns out, is their homes; nearly 60% of these dangerous spills will occur in or around the patient’s domicile. This isn’t all bad news, however, because a few modifications cou ld prevent a lot of accidents. The first thing to do is to get rid of those throw rugs that line hallways and entrances. They often fold over or bunch up, turning them into booby traps for anyone shuffling down the hall. Entering and leaving the house is a particularly high-risk activity, which is why some experts suggest removing any doorsills higher than 1/2 in. If the steps are bare wood, you can increase traction by applying non-slip treads.Because many seniors suffer from poor balance (whether from neurological deficits or from the inner-ear problems that increase naturally with aging), it also helps to install grab bars and handrails in bathrooms and along hallway.The bedroom is another major hazard area that can be made much safer with a few adjustments.Avoid stain sheets and comforters, and opt for non-slip material like wool or cotton. Easy access to devices is important, so place a lamp, telephone and flashlight near the bed within arm’s reach. Make sure the pathway between the bedroom and bathroom is completely clear, and install a night-light along the route for those emergency late-night trips.It’s a good idea to rearrange the furniture throughout the house, so that the paths between rooms are free of obstructions. Also, make sure telephone an d appliance cords aren’t strung across common walkways, where they can be tripped over.In addition to these physical precautions, there are the health precautions every aging body should take. Physical and eye examinations, with special attention to cardiac and blood-pressure problems, should be performed annually to rule out serious medical conditions. Blood pressure that’s too low or an irregular heartbeat can put you at risk for fainting and falling. Don’t forget to take calcium and vitamin D, two critical factors in developing strong bones. Finally, enrolling in an exercise programme at your local gym can improve agility, strength, balance and coordination—all important skills that can keep you on your feet and off the floor.17.

Even among those who knew nothing about him, expressions of surprise lit up their dark, liquid eyes. He was a man not expected to be there.Not only was his stature substantially greater than that of the diminutive Tibetans, but it wasalso obvious from his bearing - and his new broadcloak, which covered a much-too-tight army uniform - that he came from a markedly loftier station in life than did the average Tibetan. Among a people virtually bereft of possessions, he had fewer still, consisting solely of a rounded bundle about a foot in diameter slung securely by a cord over his shoulder. The material the bundle was wrapped in was of a rough Tibetan weave, which did not augur that the content was of any greater value - except for the importance he seemed to ascribe to it, never for a moment releasing his grip.His objective was a tiny huddle of buildings perched halfway up an enormous valley wall across from him, atop a great wooded spur jutting out from the lower lap of the 22,493-foot Ama Dablum, one of the most majestic mountains on earth. There was situated Tengboche, the most famous Buddhist monastery in the Himalayas, its setting unsurpassed for magnificence anywhere on the planet.From the top of the spur, one's eyes sweep 12 miles up the stupendous Dudh Kosi canyon to the six-mile-long granite wall of cliff of Nuptse at its head. If Ama Dablum is the Gatekeeper, then the sheer cliff of Nuptse, never less than four miles high, is the Final Protector of the highest and mightiest of them all: Chomolongma, the Mother Goddess of the World, to the Tibetans; Sagarmatha, the Head of the Seas, to the Nepalese; and Everest to the rest of us. And over the great barrier of Nuptse She demurely peaks.It was late in the afternoon - when the great shadows cast by the colossal mountains were descending into the deep valley floors - before he reached the crest of the spur and shuffled to a stop just past Tengboche's entrance gompa. His chest heaving in the rarefied air, he removed his hand from the bundle - the first time he had done so - and wiped grimy rivulets of sweat from around his eyes with the fingers of his mired hand.His narrowed eyes took in the open sweep of the quiet grounds, the pagoda-like monastery itself, and the stone buildings that tumbled down around it like a protective skirt. In the distance the magic light of the magic hour lit up the plume flying off Chomolongma's 29,029-foot-high crest like a bright, welcoming banner.His breathing calmed, he slowly, stiffly struggled forward and up the rough stone steps to the monastery entrance. There he was greeted with a respectful nameste -"1 recognize the divine in you" - from a tall, slim monk of about 35 years, who hastily set aside a twig broom he had been using to sweep the flagstones of the inner courtyard. While he did so, the visitor noticed that the monk was missing the small finger on his left hand. The stranger spoke a few formal words in Tibetan, and then the two disappeared inside.Early the next morning the emissary - lightened of his load - appeared at the monastery entrance, accompanied by the same monk and the elderly abbot. After a bow of his head. Which was returned much more deeply by the two ocher-robed residents, he took his leave. The two solemn monks watched, motionless, until he dipped over the ridge on which the monastery sat, and out of sight.Then, without a word, they turned and went back inside the monastery.26.
