As we hurried towa rd the house, with its welcoming light, I noticed a car pulling out from the cu rb. Just ahead, another car was waiting to back into the parking space -- a rar e commodity in crowded Manhattan. But before he could do so another car ca me up from behind, and sneaked into the spot. That's dirty pool, I thought.While my wife went ahead into our friend's house, I stepped into the str eet to give the guilty driver a piece of my mind. A man in work clothes rolle d down the window."Hey," I said, "this parking space belongs to that guy," I gestured toward the man ahead, who was looking back angrily. I thought I was being a good Samaritan, I guess -- and I remember that the moment I was feeling pretty manly in my new trench coat."Mind your own business!" the driver told me."No," I said. "You don't understand. That fellow was waiting to back intothis space."Things quickly heated up, until finally he leaped out of the car. My God, he was colossal. He grabbed me and bent me back over the hood of his car a s if I was a rag doll. The sleet stung my face. I glanced at the other driver, l ooking for help, but he gunned his engine and hightailed it out of there.The huge man shook his rock of a fist to me, brushing my lip and cutting the inside of my mouth against my teeth. I tasted blood. I was terrified. He snarled and threatened, and then told me to beat it.Almost in a panic, I scrambled to my friend's front door. As a former Mar ine, as a man, I felt utterly humiliated. Seeing that I was shaken, my wife an d friends asked me what had happened. All I could bring myself to say was t hat I had an argument about a parking space. They had the sensitivity to let it go at that.I sat stunned. Perhaps half an hour later, the doorbell rang. My blood ran cold. For some reason I was sure that the bruiser had returned for me. My ho stess got up to answer it, but I stopped her. I felt morally bound to answer it myself.I walked down the hallway with dread. Yet I knew I had to face up to m y fear. I opened the door. There he stood, towering. Behind him, the sleet ca me down harder than ever."I came back to apologize," he said in a low voice. "When I got home, I said to myself, 'what right I have to do that?' I'm ashamed of myself. All I ca n tell you is that the Brooklyn Navy Yard is closing. I've worked there for ye ars. And today I got laid off. I'm not myself. I hope you'll accept my apology. "I often remember that big man. I think of the effort and courage it took f or him to come back to apologize. He was man at last.And I remember that after I closed the door, my eyes blurred, as I stood i n the hallway for a few moments alone.1. On what occasion is the author likely to be moved?A.

While progress toward maturity is positively correlated with differentiation between m otivation and cognition, tension will, even in the mature adult, militate towards a narrowing of the range of perception.Cognition can be seen as the first step in the sequence events leading fro m the external stimulus to the behavior of the individual. The child develops f rom belief that all things are an extension of its own body to the recognition that objects exist independent of his perception. He begins to demonstrate awar eness of people and things which are removed from his sensory apparatus and initiates goal-directed behaviors. He may, however, refuse to recognize the exi stence of barriers to the attainment of his goal, despite the fact that his cogniti on of these objects has been previously demonstrated.In the primitive beings, goal-directed behavior can be very simple motivat ed. The presence of an attractive object will cause an infant to reach for it; it s removal will result in the cessation of that action. Studies have shown no ev idence of the infant's frustration; rather, it appears that the infant ceases to des ire the object when he cannot see it. Further indications are that the infant's at tention to the attractive object increase as a result of its not being in his grasp. In fact, if he holds a toy and another is presented, he is likely to drop the fi rst in order to clutch the second. Often, once he has the one desired in his ha nds, he loses attention and turns to something else.In adult life, mere cognition can be similarly motivational, although the visible presence of the opportunity is not required as the instigator of response. The mature adult modifies his reaction by obtaining information, interpreting it, and examining consequences. He formulates a hypothesis and attempts to test it. He searches out implicit relationships, examines all factors, and differentiates among them. Just as the trained artist can separate the value of color, compo sition, and technique, while taking in and evaluating the whole work, so, too, t he mature person brings his cognitive learning strengths to bear in appraising a situation.Understanding that cognition is separate from action, his reactions are only minimally guided from conditioning, and take into consideration anticipatable events.The impact of the socialization process, particularly that of parental and so cial group ideology, may reduce cognitively directed behavior. The tension thus produced, as for instance the stress of fear, anger, or extreme emotion, will o ften be the overriding influence.The evolutionary process of development from body schema through cogni tive learning is similarly manifested in the process of language acquisition. Au diting develop first, reading and writing much later on. Not only is this eviden t in the development of the individual being from infancy on, but also in the development of language for humankind.Every normal infant has the physiological equipment necessary to produce sound, but the child must first master their use for sucking, biting, and chewin g before he can control his equipment for use in producing the sounds of lang uage. The babble and chatter of the infant are precursors to intelligible vocal c ommunication.From the earlier times, it is clear that language and human thought have been intimately connected. Sending or receiving messages, from primitive warni ngs of danger to explaining creative or reflective thinking, this aspect of cognit ive development is also firmly linked to the needs and aspirations of society.5.

Sending or receiving messages.Passage 3Every minute of every day, what ecologist James Carlton calls a global ―c onveyor belt‖ redistributes ocean organisms. It‘s a planetwide biological disrupti on that scientists have barely begun to understand.Dr. Carlton –an oceanographer at Williams College in Williams town, M ass. –explains that, at any given moment, ―there are several thou sand [marine] species [traveling] … in the ballast water of ships.‖ These creatures move fro m coastal waters where they fit into the local web of life to places where so me of them could tear that web apart. This is the larger dimension of the infa mous invasion of fish-destroying, pipe-clogging zebra mussels.Such voracious invaders at least make their presence known. What concer ns Carlton and his fellow marine ecologists is the lack of knowledge about the hundreds of alien invaders that quietly enter coastal waters around the world every day. Many of them probably just die out. Some benignly –or every ben eficially –join the local scene. But some will make trouble.In one sense, this is an old story. Organisms have ridden ships for centuri es. They have cl ung to hulls and come along with cargo. What‘ new is the sc ale and speed of the migrations made possible by the massive volume of ship-ballast water –taken in to provide ship stability –continuously moving around the world….Ships load up with ballast water and its inhabitants in coastal waters of o ne port and dump the ballast in another port that may be thousands of kilomet ers away. A single load can run to hundreds of thousands of gallons. Some larger ships take on as much as 40 million gallons. The creatures that come alo ng tend to be in their larva freefloating stage. When discharged in alien waters they can mature into crabs, jellyfish, slugs, and many other forms.Since the problem involves coastal species, simply banning ballast dumps i n coastal waters would, in theory, solve it. Coastal organisms in ballast water that is flushed into midocean would not survive. Such a ban has worked for t he North American Inland Waterway. But it would be hard to enforce it world wide. Heating ballast water or straining it should also halt the species spread. But before any such worldwide regulations were imposed, scientists would nee d a clearer view of what is going on.The continuous shuffling of marine organisms has changed the biology of the sea on a global scale. It can have devastating effects as in the case of the American comb jellyfish that recently invaded the black Sea. It has destroyed that sea‘s anchovy fishery by eating anchovy eggs. It may soon spread to we stern and northern European waters.The marit ime nations that created the biological ―conveyor belt‖ should su pport a coordinated international effort to find out what is going on and what should be done about it.9. According to Dr. Carlton, ocean organisms areA. being moved to new environments.B. destroying the planet.C. succumbing to the zebra mussel.D. developing alien characteristics.10. Oceanographers are concerned becauseA. their knowledge of this phenomenon is limited.B. they believe the oceans are dying.C. they fear an invasion from outer-space.D. they have identified thousands of alien webs.11. According to Marine ecologists, transplanted marine speciesA. may upset the ecosystems of coastal waters.B. are all compatible with one another.C. can only survive in their home waters.D. sometimes disrupt shipping lanes.12. The identified cause of the problem isA. the rapidity with which larvae mature.B. a common practice of the shipping industry.C. a centuries old species.D. the world wide movement of ocean currents.13.

Shall it be radia nt with the sky of Italy or eloquent with the beau ideal of Greece? Shall it br eathe odor and languor from the orient, or chivalry from the occident? or gaye ty from France? or vigor from England? No, no; these are all too old—my o wn New England; the land of bright fires and strong hearts; the land of deeds, and not of words; the land of fruits, and not of flowers; the land often spoke n against, yet always respected: ― the latchet of whose shoes the nations of th e earth are not worthy to unloose.‖Now from this very heroic apostrophe, you may suppose that I have some thing very heroic to tell. By no means. It is merely a little introductory breeze of patriotism, such as occasionally brushes over every mind, bearing on its wi ngs the remembrance of all we ever loved and cherished in the land of our ea rly years; and if it should seem to be rodomontade to any people in other part s of the earth, let them only imagine it to be said about ―Old Kentucky‖, ―Ol d England‖, or any other corner of the world in which they happened to be b orn and they will find it quite rational.But, as touching our story, it is time to begin. Did you ever see the little village of Newbury, in New England? I dare say you never did; for it was j ust one of those out-of-the-way places where nobody ever came unless they ca me on purpose: a green little hollow, wedged like a bird‘s next between half a dozen high hills, that kept off the wind and kept out foreigners; so that the little place was s straitly sui generis as if there were not another in the world. The inhabitants were all of that respectable old steadfast family who make it a point to be born, bred, married, to die, and be buried all in the selfsame sp ot. There were just so many houses, and just so many people lived in them; a nd nobody ever seemed to be sick, or to die either, at least while I was there. The natives grew old till they could not grow any older, and then they stood still, and lasted from generation to generation. There was, too, an unchangeabi lity about all the externals of Newbury. Here was a red house, and there was a brown house, and across the way was a yellow house; and there was a straggling rail fence or a tribe of mullein stalks between. The minister lived here, and Squire Moses lived there, and Deacon Hart lived under the hill, and Mes srs. Nadab and Abihu Peters lived by the crossroad, and the old ―wider‖ Smit h lived by the meeting-house, and Ebenezer Camp kept a shoemaker‘s shop on one side, and Patience Mosely kept a m illiner‘s shop in front; and there was old Comfort Scran, who kept a store for the whole town, and sold axeheads, brass thimbles, licorice balls, fancy handkerchiefs, and everything else you can think of. Here, too, was the general post-office, where you might see letters marvelously folded, directed wrong side upward, stamped with a thimble, and s uperscribed to some of the Dollys, or Pollys, or Peters, or Moseses aforename d or not named.For the rest, as to manners, morals, arts, and sciences, the people in New bury always went to their parties at three o‘clock in the afternoon, and came home before dark; always stopped all work the minute the sun was down on Saturday night; always went to meeting on Sunday; had a schoolhouse with all the ordinary inconveniences; were in neighborly charity with each other; read their Bibles, feared their God, and were content with such things as they had —the best philosophy, after all.14.In the first paragraph the author contrasts the East and the West asA.indolent and gallant.B. charming and rude.C. foreign and familiar.D. passive and aggressive.15.

The author‘s view of Newbury isA. retrospective.B. detached.C. impartial.D. skeptical.Passage 5Just over 10 years ago, Ingmar Bergman announced that the widely acclai med Fanny and Alexander would mark his last hurrah as s filmmaker. Althoug h some critics had written him off as earnest but ponderous, others were sadde ned by the departure of an artist who had explored cinematic moods –from h igh tragedy to low comedy –during his four-decade career.What nobody foresaw was that Bergman would find a variety of ways to circumvent his own retirement –directing television movies, staging theater pro ductions, and writing screenplays for other filmmakers to direct. His latest ente rprise as a screenwriter, Sunday’s Children, completes a trilogy of family-orient ed movies that began with Fanny and Alexander and continued with The Best Intentions written by Bergman and directed by Danish filmmaker Bille August.Besides dealing with members of Bergman‘s family in byg one times –it begins a few years after The Best Intentions leaves off –the new picture was directed by Daniel Bergman, his youngest son. Although it lacks the urgency a nd originality of the elder Bergman‘s greatest achievements, such as The Silen ce and Persona, it has enough visual and emotional interest to make a worthy addition to his body of work.Set in rural Sweden during the late 1920s, the story centers on a young b oy named Pu, clearly modeled on Ingmar Bergman himself. Pu‘s father is a co untry clergyman whose duties include traveling to the capital and ministering t o the royal family. While this is an enviable position, it doesn‘t assuage probl ems in the pastor‘s marriage. Pu is young enough to be fairly oblivious to suc h difficulties, but his awareness grows with the passage of time. So do the su btle tensions that mark Pu‘s own relationship with his father, whose desire to show affection and compassion is hampered by a certain stiffness in his demea nor and chilliness in his emotions.The film‘s m ost resonant passages take place when Pu learns to see his f ather with new clarity while accompanying him on a cross-country trip to another parish. In a remarkable change of tone, this portion of the story is punctua ted with flash-forwards to a time 40 years in the future, showing the relations hip between parent and child to be dramatically reversed. The father is now ca red for by the son, and desires a forgiveness for past shortcomings that the yo unger man resolutely refuses to grant.Brief and abrupt though they are, these scenes make a pungent contrast w ith the sunny landscapes and comic interludes in the early part of the movie.Sunday’s Children is a film of many levels, and all are skillfully handled by Daniel Bergman in his directional debut. Gentle scenes of domestic content ment are sensitively interwoven with intimations of underlying malaise. While t he more nostalgic sequences are photographed with an eye-dazzling beauty that occasionally threatens to become cloying, any such result is foreclosed by the jagged interruptions of the flash-forward sequences –an intrusive device that few filmmakers are agile enough to handle successfully, but that is put to imp ressive use by the Bergman team.Henrik Linnros gives a smartly turned performance as young Pu, and Tho mmy Berggren –who starred in the popular Elvira Madigan years ago –is st eadily convincing as his father. Top honors go to the screenplay, though, whic h carries the crowded canvas of Fanny and Alexander and the emotional ambi guity of The Best Intentions into fresh and sometimes fascinating territory.19. Over the years critical views of Bergmans‘ work haveA. without exception been positive.B. deplored his seriousness.C. often been antithetical.D. usually focused on his personality.20. The subject matter of Sunday’s ChildrenA. is presented chronologically.B. takes place in the 19th century.C. occurs all in one locale.D. is derived from reminiscences.21.

The reviewer thinks that the ―flash forward‖ technique isA. seldom handled skillfully.。
