《新概念英语》第四册二十二单元介副词填空

《新概念英语》第四册二十二单元介副词填空1.Although mankind has undergone no general improvement in intelligence or morality, it hasmade extraordinary progress the accumulation of knowledge. 虽然人类在智力和道德上没有得到普遍提高，但在知识积累方面却取得了巨大的进步。

（NCE-4-22）2.With the invention of writing, a great advance was made, for knowledge could then be notonly communicated but also stored. Libraries made education possible, and education in its turn added to libraries: the growth of knowledge followed a kind of compound-interest law, which was greatly enhanced by the invention of printing. 随着书写的发明，又迈进了一大步，因为这样一来，知识不仅能交流，而且能储存了。

藏书使教育成为可能，而教育反过来又丰富了藏书，因为知识的增长遵循桌一种“滚雪球”的规律。

印刷术的发明又大大提高了知识增长的速度。

（NCE-4-22）3.What is called ‘modern civilization’ is not the result of a balanced development of all man'snature, but of accumulated knowledge applied to practical life. 所谓“现代文明”并不是人的天性平衡发展的结果，而是积累起来的知识应用到实际生活中的结果。

Well, they wanted to do something useful.Soon, however, they realized what they had undertaken.They moved in with a local family, the Harrisons，and, like them, had little privacy, rare baths, and a blanket of snow on their quilt when they woke up in the morning.Some mornings, Rosamond and Dorothy would arrive at the schoolhouse to find the children weeping from the cold.In spring, the snow was replaced by mud over ice.In Wickenden's book, she expanded on the history of the West and also on feminism, which of course influenced the girls' decision to go to Elkhead.A hair-raising section concerns the building of the railroads, which entailed(牵涉) drilling through the Rockies, often in blinding snowstorms.The book ends with Rosamond and Dorothy's return to Auburn.Wickenden is a very good storyteller.The sweep of the land and the stoicism(坚忍) of the people move her to some beautiful writing.Here is a picture of Dorothy Woodruff, on her horse, looking down from a hill top：“When the sun slipped behind the mountains, it shed a rosy glow all around them.Then a full moon rose.The snow was marked only by small animals：foxes, coyotes, mice, and varying hares, which turned white in the winter.”语篇解读：本文是一篇说明文。

新概念英语第四册课文word版

Lesson1We can read of things that happened 5,000 years ago in the Near East, where people first learned to write. But there are some parts of the world where even now people cannot write. The only way that they can preserve their history is to recount it as sagas--legends handed down from one generation of story-tellers to another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacific Islands came from. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago.But the first people who were like ourselves lived so long ago that even their sagas, if they had any, are forgotten. So archaeologists have neither history nor legends to help them to find out where the first 'modern men' came from. Fortunately, however, ancient men made tools of stone, especially flint, because this is easier to shape than other kinds. They may also have used wood and skins, but these have rotted away. Stone does not decay, and so the tools of longago have remained when even the bones of the men who made them have disappeared without trace.Lesson2Why, you may wonder, should spiders be our friends ? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction of the number destroyed by spiders. Moreover, unlike some of the other insect eaters, spiders never do the least harm to us or our belongings. Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance for a spider always has eight legs and an insect never more than six.How many spiders are engaged in this work on our behalf ? One authority on spiders made a census of the spiders in a grass field in the south of England, and he estimated that there were more than 2,250,000 in one acre, that is something like6,000,000 spiders of different kinds on a football pitch. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by spiders in Britain in one year would be greater than the total weight of all the human beings in the country.Lesson3Modern alpinists try to climb mountains by a route which will give them good sport, and the more difficult it is, the more highly it is regarded. In the pioneering days, however, this was not the case at all. The early climbers were looking for the easiest way to the top because the summit was the prize they sought, especially if it had never been attained before. It is true that during their explorations they often faced difficulties and dangers of the most perilous nature, equipped in a manner which would make a modern climber shudder at the thought, but they did not go out of their way to court such excitement. They had a single aim, a solitary goal--the top!It is hard for us to realize nowadays how difficult it was for the pioneers. Except for one or two places such as Zermatt and Chamonix, which had rapidly become popular, Alpine villages tended to be impoverished settlements cut off from civilization by the high mountains. Such inns as there were were generally dirty and flea-ridden; the food simply local cheese accompanied by bread often twelve months old, all washed down with coarse wine. Often a valley boasted no inn at all, and climbers found shelter wherever they could--sometimes with the local priest (who was usually as poor as his parishioners), sometimes with shepherds or cheese-makers. Invariably the background was the same: dirt and poverty, and very uncomfortable. For men accustomed to eating seven-course dinners and sleeping between fine linen sheets at home, the change to the Alpsmust have been very hard indeed.Lesson4In the Soviet Union several cases have been reported recently of people who can read and detect colours with their fingers, and even see through solid doors and walls. One case concerns an 'eleven-year-old schoolgirl, Vera Petrova, who has normalvision but who can also perceive things with different parts of her skin, and through solid walls. This ability was first noticed by her father. One day she came into his office and happened to put her hands on the door of a locked safe. Suddenly she asked her father why he kept so many old newspapers locked away there, and even described the way they were done up in bundles.Vera's curious talent was brought to the notice of a scientific research institute in the town of UIyanovsk, near where she lives, and in April she was given a series of tests by a special commission of the Ministry of Health of the Russian Federal Republic. During these tests she was able to read a newspaper through an opaque screen and, stranger still, by moving her elbow over a child's game of Lotto she was able to describe the figures and colours printed on it; and, in another instance, wearing stockings and slippers, to make out with her foot the outlines and colours of a picture hidden under a carpet. Other experiments showed that her knees and shoulders had a similar sensitivity. During all these tests Vera was blindfold; and, indeed, except when blindfold she lacked the ability to perceive things with her skin. It was also found that althoughshe could perceive things with her fingers this ability ceased the moment her hands were wet.Lesson5The gorilla is something of a paradox in the African scene. One thinks one knows him very well. For a hundred years or more he has been killed, captured, and imprisoned, in zoos. His bones have been mounted in natural history museums everywhere, and he has always exerted a strong fascination upon scientists and romantics alike. He is the stereotyped monster of the horror films and the adventure books, and an obvious (though not perhaps strictly scientific) linkwith our ancestral past.Yet the fact is we know very little about gorillas. No really satisfactory photograph has ever been taken of one in a wild state, no zoologist, however intrepid, has been able to keep the animal under close and constant observation in the dark jungles in which he lives. Carl Akeley, the American naturalist, led two expeditions in the nineteen-twenties, and now lies buried among the animals heloved so well. But even he was unable to discover how long the gorilla lives, or how or why it dies, nor was he able to definethe exact social pattern of the family groups, or indicate the final extent of their intelligence. All this and many other things remain almost as much a mystery as they were when the French explorer Du Chaillu first described the animal to the civilized world a century ago. The Abominable Snowman who haunts the imagination of climbers in the Himalayas is hardly more elusive.Lesson6People are always talking about' the problem of youth '. If there is one—which I take leave to doubt--then it is older people who create it, not the young themselves. Let us get down to fundamentals and agree that the young are after all human beings--people just like their elders. There is only one difference between an old man and a young one: the young man has a glorious future before him and the old one has a splendid future behind him: and maybe that is where the rub is.When I was a teenager, I felt that I was just young and uncertain--that I was a new boy in a huge school, and I would have been very pleased to be regarded as something so interesting as a problem. For one thing, being a problem givesyou a certain identity, and that is one of the things the young are busily engaged in seeking.I find young people exciting. They have an air of freedom, and they have not a dreary commitment to mean ambitions or love of comfort. They are not anxious social climbers, and they have no devotion to material things. All this seems to me to link them with life, and the origins of things. It's as if they were in some sense cosmic beings in violent an lovely contrast with us suburban creatures. All that is in my mind when I meet a young person. He may be conceited, ill- mannered, presumptuous of fatuous, but I do not turn for protection to dreary cliches about respect for elders--as if mere age were a reason for respect. I accept that we are equals, and I will argue with him, as an equal, if I think he is wrong.Lesson7I am always amazed when I hear people saying that sport creates goodwill between the nations, and that if only the common peoples of the world could meet one another at football or cricket, they would have no inclination to meet on the battlefield. Even if one didn't know from concrete examples (the 1936 Olympic Games, for instance) that internationalsporting contests lead to orgies of hatred, one could deduce it from general principles.Nearly all the sports practised nowadays are competitive. You play to win, and the game has little meaning unless you do your utmost to win. On the village green, where you pick up sides and no feeling of local patriotism is involved, it is possible to play simply for the fun and exercise: but as soon as the question of prestige arises, as soon as you feel that you and some larger unit will be disgraced if you lose, the most savage combative instincts are aroused. Anyone who has played even in a school football match knows this. At the international level sport is frankly mimic warfare. But the significant thing is not the behaviour of the players but the attitude of the spectators: and, behind the spectators, of the nations. who work themselves into furies over these absurd contests, and seriously believe--at any rate for short periods--that running, jumping and kicking a ball are tests of national virtue.Lesson8Parents have to do much less for their children today than they used to do, and home has become much less of a workshop. Clothes can be bought ready made, washing can go to the laundry, foodcan be bought cooked, canned or preserved, bread is baked and delivered by the baker, milk arrives on the doorstep, meals can be had at the restaurant, the works' canteen, and the school dining-room.It is unusual now for father to pursue his trade or other employment at home, and his children rarely, if ever, see him at his place of work. Boys are therefore seldom trained to follow their father's occupation, and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money, and soon acquires a feeling of economic independence. In textile areas it has long been customary for mothers to go out to work, but thispractice has become so widespread that the working mother is now a not unusual factor in a child's home life, the number of married women in employment having more than doubled in the last twenty-five years. With mother earning and his older children drawing substantial wages father is seldom the dominant figure that he still was at the beginning of the century. When mother workseconomic advantages accrue, but children lose something of great value if mother's employment prevents her from being home to greet them when they return from school.Lesson9Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echo-location in bats to see a case in which the voice plays a strictly utilitarian role.To get a full appreciation of what this means we must turn first to some recent human inventions. Everyone knows that if he shouts in the vicinity of a wall or a mountainside, an echo will come back. The further off this solid obstruction the longer time will elapse for the return of the echo. A sound made by tapping on the hull of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps and the receipt of the echoes the depth of the sea at that point can be calculated. So was born the echo-sounding apparatus, now in general use in ships. Every solid object will reflect a sound, varying ac- cording to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved apparatus, it is now possible not only to locate a shoal butto tell if it is herring, cod, or other well-known fish, by the pattern of its echo .A few years ago it was found that certain bats emit squeaks and by receiving the echoes they could locate and steer clear of obstacles--or locate flying insects on which they feed. This echo-location in bats is often compared with radar, the principle of which is similar.Lesson10In our new society there is a growing dislike of original, creative men. The manipulated do not understand them; the manipulators fear them. The tidy committee men regard them with horror, knowing that no pigeonholes can be found for them. We could do with a few original, creative men in our political life—if only to create some enthusiasm, release some energy--but where are they? We are asked to choose between various shades of the negative. The engine is falling to pieces while the joint owners of the car argue whether the footbrake or the handbrake should be applied. Notice how the cold, colourless men, without ideas and with no other passion but a craving for success, get on in this society, capturing one plum after another and taking the juice and taste out of them.Sometimes you might think the machines we worship make all the chief appointments, promoting the human beings who seem closest to them. Between mid-night and dawn, when sleep will not come and all the old wounds begin to ache, I often have a nightmare vision of a future world in which there are billions of people, all numbered and registered, with not a gleam of genius anywhere, not an original mind, a rich personality, on the whole packed globe. The twin ideals of our time, organization and quantity, will have won for ever.Lesson11Alfred the Great acted as his own spy, visiting Danish camps disguised as a minstrel. In those days wandering minstrels were welcome everywhere. They were not fighting men, and their harp was their passport. Alfred had learned many of their ballads in his youth, and could vary his programme with acrobatic tricks and simple conjuring.While Alfred's little army slowly began to gather at Athelney, the king himself set out to penetrate the camp of Guthrum, the commander of the Danish invaders. These had settled down for the winter at Chippenham: thither Alfred went. He noticed at once that discipline was slack: the Danes hadthe self-confidence of conquerors, and their security precautions were casual. They lived well, on the proceeds of raids on neighbouring regions. There they collected women as well as food and drink, and a life of ease had made them soft.Alfred stayed in the camp a week before he returned to Athelney. The force there assembled was trivial compared with the Danish horde. But Alfred had deduced that the Danes were no longer fit for prolonged battle : and that their commissariat had no organization, but depended on irregular raids.So, faced with the Danish advance, Alfred did not risk open battle but harried the enemy. He was constantly on the move, drawing the Danes after him. His patrols halted the raiding parties: hunger assailed the Danish army. Now Alfred began a long series of skirmishes--and within a month the Danes had surrendered. The episode could reasonably serve as a unique epic of royal espionage!Lesson12What characterizes almost all Hollywood pictures is their inner emptiness. This is compensated for by an outer impressiveness. Such impressiveness usually takes the form oftruly grandiose realism. Nothing is spared to make the setting, the costumes, all of the surface details correct. These efforts help to mask the essential emptiness of the characterization, and the absurdities and trivialities of the plots. The houses look like houses, the streets look like streets; the people look and talk like people; but they are empty of humanity, credibility, and motivation. Needless to say, the disgraceful censorship code is an important factor in predetermining the content of these pictures. But the code does not disturb the profits, nor the entertainment value of the films; it merely helps to prevent them from being credible. It isn't too heavy a burden for the industry to bear. In addition to the impressiveness of the settings, there is a use of the camera, which at times seems magical. But of what human import is all this skill, all this effort, all this energy in the production of effects, when the story, the representation of life is hollow, stupid, banal, childish ?Lesson13Oxford has been ruined by the motor industry. The peace which Oxford once knew, and which a great university city should always have, has been swept ruthlessly away; and nobenefactions and research endowments can make up for the change in character which the city has suffered. At six in the morning the old courts shake to the roar of buses taking the next shift to Cowley and Pressed Steel, great lorries with a double deck cargo of cars for export lumber past Magdalen and the University Church. Loads of motor-engines are hurried hither and thither and the streets are thronged with a population which has no interest in learning and knows no studies beyond servo-systems and distributors, compression ratios and camshafts.Theoretically the marriage of an old seat of learning and tradition with a new and wealthy industry might be expected to produce some interesting children. It might have been thought that the culture of the university would radiate out and transform the lives of the workers. That this has not happened may be the fault of the university, for at both Oxford and Cambridge the colleges tend tolive in an era which is certainly not of the twentieth century, and upon a planet which bears little resemblance to the war-torn Earth. Wherever the fault may lie the fact remains that it is the theatre at Oxford and not at Cambridge which is on the verge of extinction, and the only fruit of thecombination of industry and the rarefied atmosphere of learning is the dust in the streets, and a pathetic sense of being lost which hangs over some of the colleges.Lesson14Some old people are oppressed by the fear of death. In the young there is a justification for this feeling. Young men who have reason to fear that they will be killed in battle may justifiably feel bitter in the thought that they have been cheated of the best things that life has to offer. But in an old man who has known human joys and sorrows, and has achieved whatever work it was in him to do, the fear of death is somewhat abject and ignoble. The best way to overcome it- so at least it seems to me----is to make your interests gradually wider and more impersonal, until bit by bit the walls of the ego recede, and your life becomes increasingly merged in the universal life. An individual human existence should be like a river--small at first, narrowly contained within its banks, and rushing passionately past boulders and over waterfalls. Gradually the river grows wider, the banks recede, the waters flow more quietly, and in the end, without any visible break, they become merged in the sea, and painlessly lose theirindividual being. The man who, in old age, can see his life in this way, will not suffer from the fear of death, since the things he cares for will continue. And it, with the decay of vitality, weariness increases, the thought of rest will be not unwelcome. I should wish to die while still at work, knowing that others will carry on what I can no longer do, and content in the thought that what was possible has been done.Lesson15When anyone opens a current account at a bank, he is lending the bank money, repayment of which he may demand at any time, either in cash or by drawing a cheque in favour of another person. Primarily, the banker-customer relationship is that of debtor and creditor--who is which depending on whether the customer's account is in credit or is overdrawn. But, in addition to that basically simple concept, the bank and its customer owe a large number of obligations to one another. Many of these obligations can give rise to problems and complications but a bank customer, unlike, say, a buyer of goods, cannot complain that the law is loaded against him. The bank must obey its customer's instructions, and not those of anyone else. When, for example, a customer first opens anaccount, he instructs the bank to debit his account only in respect of cheques drawn by himself. He gives the bank specimens of his signature, and there is a very firm rule that the bank has no right or authority to pay out a customer's money on a cheque on which its customer's signature has been forged. It makes no difference that the forgery may have been a very skilful one: the bank must recognize its customer's signature. For this reason there is no risk to the customer in the modern practice, adopted by some banks, of printing the customer's name on his cheques. If this facilitates forgery it is the bank which will lose, not the customer.Lesson16The deepest holes of all are made for oil, and they go down to as much as 25,000 feet. But we do not need to send men down to get the oil out, as we must with other mineral deposits. The holes are only borings, less than a foot in diameter. My particular experience is largely in oil, and the search for oil has done more to improve deep drilling than any other mining activity. When it has been decided where we are going to drill, we put up at the surface an oil derrick. It has to be tall because it is like a giant block and tackle, and we have tolower into the ground and haul out of the ground great lengths of drill pipe which are rotated by an engine at the top and are fitted with a cutting bit at the bottom.The geologist needs to know what rocks the drill has reached, so every so often a sample is obtained with a coring bit. It cuts a clean cylinder of rock, from which can be seen he strata the drill has been cutting through. Once we get down to the oil, it usually flows to the surface because great pressure, either from gas or water, is pushing it. This pressure must be under control, and we control it by means of the mud which we circulate down the drill pipe. We endeavour to avoid the old, romantic idea of a gusher, which wastes oil and gas. We want it to stay down the hole until we can lead it off in a controlled manner.Lesson17The fact that we are not sure what 'intelligence' is, nor what is passed on, does not prevent us from finding it a very useful working concept, and placing a certain amount of reliance on tests which 'measure' it.In an intelligence test we take a sample of an individual's ability to solve puzzles and problems of various kinds, andif we have taken a representative sample it will allow us to predict successfully the level of performance he will reach in a wide variety of occupations.This became of particular importance when, as a result of the 1944 Education Act, secondary schooling for all became law, and grammar schools, with the exception of a small number of independent foundation schools, became available to the whole population. Since the number of grammar schools in the country could accommodate at most approximately 25 per cent of the total child population of eleven-plus, some kind of selection had to be made. Narrowly academic examinations and tests were felt, quite rightly, to be heavily weighted in favour of children who had had the advantage of highly-academic primary schools and academically biased homes. Intelligence tests were devised to counteract this narrow specialization, by introducing problems which were not based on specifically scholastically-acquired knowledge. The intelligence test is an attempt to assess the general ability of any child to think, reason, judge, analyse and synthesize by presenting him with situations, both verbal and practical, which are within his range of competence and understanding.Lesson18Two factors weigh heavily against the effectiveness of scientific in industry. One is the general atmosphere of secrecy in which it is carried out, the other the lack of freedom of the individual research worker. In so far as any inquiry is a secret one, it naturally limits all those engaged in carrying it out from effective contact with their fellow scientists either in other countries or in universities, or even , often enough , in other departments of the same firm. The degree of secrecy naturally varies considerably. Some of the bigger firms are engaged in researches which are of such general and fundamental nature that it is a positive advantage to them not to keep them secret. Yet a great many processes depending on such research are sought for with complete secrecy until the stage at which patents can be taken out. Even more processes are never patented at all but kept as secret processes. This applies particularly to chemical industries, where chance discoveries play a much larger part than they do in physical and mechanical industries. Sometimes the secrecy goes to such an extent that the whole nature of the research cannot be mentioned. Many firms, for instance, have great difficulty in obtaining technical or scientific booksfrom libraries because they are unwilling to have their names entered as having taken out such and such a book for fear the agents of other firms should be able to trace the kind of research they are likely to be undertaking.Lesson19A gentleman is, rather than does. He is interested in nothing in a professional way. He is allowed to cultivate hobbies, even eccentricities, but must not practise a vocation. He must know how to ride and shoot and cast a fly. He should have relatives in the army and navy and at least one connection in the diplomatic service. But there are weaknesses in the English gentleman's ability to rule us today. He usually knows nothing of political economy and less about how foreign countries are governed. He does not respect learning and prefers 'sport '. The problem set for society is not the virtues of the type so much as its adequacy for its function, and here grave difficulties arise. He refuses to consider sufficiently the wants of the customer, who must buy, not the thing he desires but the thing the English gentleman wants to sell. He attends inadequately to technological development. Disbelieving in the necessity of large-scale production in the modern world,he is passionately devoted to excessive secrecy, both in finance and method of production. He has an incurable and widespread nepotism in appointment, discounting ability and relying upon a mystic entity called 'character,' which means, in a gentleman's mouth, the qualities he traditionally possesses himself. His lack of imagination and the narrowness of his social loyalties have ranged against him one of the fundamental estates of the realm. He is incapable of that imaginative realism which admits that this is a new world to which he must adjust himself and his institutions, that every privilege he formerly took as of right he can now attain only by offering proof that it is directly relevant to social welfare.Lesson20In the organization of industrial life the influence of the factory upon the physiological and mental state of the workers has been completely neglected. Modern industry is based on the conception of the maximum production at lowest cost, in order that an individual or a group of individuals may earn as much money as possible. It has expanded without any idea of the true nature of the human beings who run the machines, and without。

《新概念英语》第四册二十八单元介副词填空1.This is a skeptical age, but although our faith in many of the things in which our forefathersfervently believed has weakened, our confidence in the curative properties of the bottle of medicine remains the same as theirs. 这是一个怀疑一切的时代，可是虽然我们对我们祖先笃信的许多事物已不太相信，我们对瓶装药品疗效的信心仍与祖辈一样坚定。

（NCE-4-28）2.This modern faith in medicines is roved by the fact that the annual drug bill of the HealthServices is mounting to astronomical figures and shows no signs at present of ceasing to rise.卫生部门的年度药费上升到了天文数字，并且目前尚无停止上升的迹象，这个事实证实了现代人对药物的信赖。

（NCE-4-28）3.There is no quicker method of disposing of patients than by giving them what they are askingfor, and since most medical men in the Health Services are overworked and have little time for offering time-consuming and little-appreciated advice on such subjects as diet, right living, and the need for abandoning bad habits, etc., the bottle, the box, and the jar are almost always granted them. 因为卫生部门的大多数医生都越负荷工作，所以没有多少时间提出一些既费时而又不受人欢迎的忠告，如注意饮食、生活有规律、需要克服环习惯等等，结果就是把瓶药、盒药、罐药开给看病的人而完事大吉。
