First listen and then answer the following question.

What does the "uniquely rational way" for us to municate with other intelligent beings in space depend on?

We must conclude from the work of those who have studied the origin of life, that given a pla only approximately like our own, life is almost certain to start. Of all the plas in our solar system, we ware now pretty certain the Earth is the only one on which life can survive. Mars is too dry and poor in oxygen, Venus far too hot, and so is Mercury, and the outer plas have temperatures near absolute zero and

hydrogen-dominated atmospheres. But other suns, start as the astronomers call them, are bound to have plas like our own, and

as is the number of stars in the universe is so vast, this possibility bees virtual certainty. There are one hundred thousand million starts in our own Milky Way alone, and then there are three thousand million other Milky Ways, or galaxies, in the universe. So the number of the stars that we know exist is now estimated at about 300 million million million.

Although perhaps only 1 per cent of the life that has started somewhere will develop into highly plex and intelligent patterns, so vast is the number of plas, that intelligent life is bound to be a natural part of the universe.

If then we are so certain that other intelligent life exists in the universe, why have we had no visitors from outer space yet? First of all, they may have e to this pla of ours thousands or millions of years ago, and found our then prevailing primitive state pletely uninteresting to their own advanced knowledge. Professor Ronald Bracewell, a leading American radio astronomer, argued in Nature that such a superior civilization, on a visit to our own solar system, may have left an automatic messenger behind to await the possible awakening of an advanced civilization. Such a messenger,

receiving our radio and television signals, might well

re-transmit them back to its home-pla, although what impression any other civilization would thus get from us is best left unsaid.

But here we e up against the most difficult of all obstacles to contact with people on other plas -- the astronomical distances which separate us. As a reasonable guess, they might, on an average, be 100 light years away. (A light year is the distance which light travels at 186,000 miles per second in one year, namely 6 million million miles.) Radio waves also travel at the speed of light, and assuming such an automatic messenger picked up our first broadcasts of the 1920"s, the message to its home pla is barely halfway there. Similarly, our own present primitive chemical rockets, though good enough to orbit men, have no chance of transporting us to the nearest other star, four light years away, let alone distances of tens or hundreds of light years.

Fortunately, there is a "uniquely rational way" for us to municate with other intelligent beings, as Walter Sullivan has put it in his excellent book, We Are not Alone. This depends

on the precise radio frequency of the 21-cm wavelength, or 1420 megacycles per second. It is the natural frequency of emission of the hydrogen atoms in space and was discovered by us in 1951; it must be known to any kind of radio astronomer in the universe.

Once the existence of this wave-length had been discovered, it was not long before its use as the uniquely recognizable broadcasting frequency for interstellar munication was suggested. Without something of this kind, searching for intelligences on other plas would be like trying to meet a friend in London without a pre-arranged rendezvous and absurdly wandering the streets in the hope of a chance encounter.

But there are some parts of the world where even now people cannot write.

The modern city 现代城市 In the organization of industrial life the in?uence 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 giving any consideration to the effects produced on the individuals and on their descendants by the arti?cial mode of existence imposed by the factory. The great cities have been built with no regard for us. The shape and dimensions of the skyscrapers depend entirely on the necessity of obtaining the maximum income per square foot of ground, and of offering to the tenants of?ces and apartments that please them. This caused the construction of gigantic buildings where too large masses of human beings are crowded together. Civilized men like such a way of living. While they enjoy the comfort and banal luxury of their dwelling, they do not realize that they are deprived of the necessities of life. The modern city consists of monstrous edi?ces and of dark, narrow streets full of petrol fumes and toxic gases, torn by the noise of the taxicabs, lorries and buses, and thronged ceaselessly by great crowds. Obviously, it has not been planned for the good of its inhabitants. ?一理理的 代 ?人造的?生存?方式隺加规模 I 平庸的 ?一倒夺巨?大的?大厦南满拥塞without any idea of 完全忽视without giving any consideration to

But there are some parts of the world where even now people cannot write. The only w ay that they can preserve their history is torecount it as sagas--legends handed down from one generation of story-tellersto another. These legends are useful because they can tell us somethin g aboutmigrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesianpeoples now living in th e Pacific Islands came from.

Stone does not decay, and so the tool s oflong ago have remained when even the bones of the men who made them have disappeared without trace. 3 Lesson 2 Spare that spider Why, you may wonder, should spiders be our friends ? Because they destroy somany insects, and insects include some of the greatest enemies of the humanrace. Insects would make it impossible for us to live in the world; they woulddevour all our crops and kill our flocks and herds, if it were not for the protectionwe get from insect-eating animals. We owe a lot to the birds and beasts wh o 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 dothe least harm to us or our bel ongings.Spiders are not insects, as many people think, nor even nearly related to them.One can t ell the difference almost at a glance for a spider always has eight legsand an insect never more th an 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, andhe estimated that there were more than 2,250,000 in one acre, that is something like 6,000,000 spiders of different kinds on a f ootball 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 wi th only three meals a day. It has been estimated that the weight of all the insects destroyed by spi ders in Britain in one year would be greater than the total weight of all the human beings in the c ountry.T. H.

新概念第四册课文翻译及学习笔记：Lesson10 【课文】 First listen and then answer the following question. 听录音，然后回答以下问题。 What does the computer industry thrive on apart from anarchy? Technology trends may push Silicon Valley back to the future. Carver Mead, a pioneer in integrated circuits and a professor of computer science at the California Institute of Technology, notes there are now work-stations that enable engineers to design, test and produce chips right on their desks, much the way an editor creates a newsletter on a Macintosh. As the time and cost of making a chip drop to a few days and a few hundred dollars, engineers may soon be free to let their imaginations soar without being penalized by expensive failures. Mead predicts that inventors will be able to perfect powerful customized chips over a weekend at the office -- spawning a new generation of garage start-ups and giving the U.S. a jump on its foreign rivals in getting new products to market fast. 'We've got more garages with smart people,' Mead observes. 'We really thrive on anarchy.' And on Asians. Already, orientals and Asian Americans constitute the majority of the engineering staffs at many Valley firms. And Chinese, Korean, Filipino and Indian engineers are graduating in droves from California's colleges. As the heads of next-generation start-ups, these Asian innovators can draw on customs and languages to forge tighter

Waves are the children of the struggle between ocean and atmosphere, the ongoing signatures of infinity. Rays from the sun excite and energize the atmosphere of the earth, awakening it to flow, to movement, to rhythm, to life. The wind then speaks the message of the sun to the sea and the sea transmits it on through waves -- an ancient, exquisite, powerful message. These ocean waves are among the earth”s most complicated natural phenomena. The basic features include a crest (the highest point of the wave), a trough (the lowest point), a height (the vertical distance from the trough

新概念第四册课文翻译及学习笔记：Lesson41 【课文】First listen and then answer the following question. 听录音，然后回答以下问题。At what point does the training of a captive wild elephant begin? Two main techniques have been used for training elephants, which we may call respectively the tough and the gentle. The former method simply consists of setting an elephant to work and beating him until he does what is expected of him. Apart from any moral considerations this is a stupid method of training, for it produces a resentful animal who at a later stage may well turn man-killer. The gentle method requires more patience in the early stages, but produces a cheerful, good-tempered elephant who will give many years of loyal service. The first essential in elephant training is to assign to the animal a single mahout who will be entirely responsible for the job. Elephants like to have one master just as dogs do, and are capable of a considerable degree of personal affection. There are even stories of half-trained elephant calves who have refused to feed and pined to death when by some unavoidable circumstance they have been deprived of their own trainer. Such extreme cases must probably be taken with a grain of salt, but they do underline the general principle that the relationship between elephant and mahout is the key to successful training. The most economical age to capture an elephant for training is between fifteen and twenty years, for it is then almost ready to undertake heavy work and can begin to earn its keep straight away. But animals of this age do not easily become subservient to man, and a very firm hand must be employed in the early stages. The captive elephant, still roped to a tree, plunges and screams every time a man approaches, and for several days will probably refuse all food through anger and fear. Sometimes a tame elephant is tethered nearby to give the wild one confidence, and in most cases the captive gradually quietens down and begins to accept its food. The next stage is to get the elephant to the training establishment, a ticklish business which is achieved with the aid of two tame elephants roped to the captive on either side. When several elephants are being trained at one time, it is customary for the new arrival to be placed between the stalls of two captives whose training is already well advanced. It is then left completely undisturbed with plenty of food and water so that it can absorb the atmosphere of its new home and see that nothing particularly alarming is happening to its companions. When it is eating normally, its own training begins. The trainer stands in front of the elephant holding a long stick with a sharp metal point. Two

新概念英语第四册课文翻译及学习笔记：Lesson46 【课文】 Punctuality is a necessary habit in all public affairs in civilized society. Without it, nothing could ever be brought to a conclusion; everything would be in state of chaos. Only in a sparsely-populated rural community is it possible to disregard it. In ordinary living, there can be some tolerance of unpunctuality. The intellectual, who is working on some abstruse problem, has everything coordinated and organized for the matter in hand. He is therefore forgiven if late for a dinner party. But people are often reproached for unpunctuality when their only fault is cutting things fine. It is hard for energetic, quick-minded people to waste time, so they are often tempted to finish a job before setting out to keep an appointment. If no accidents occur on the way, like punctured tires, diversions of traffic, sudden descent of fog, they will be on time. They are often more industrious, useful citizens than those who are never late. The over- punctual can be as much a trial to others as the unpunctual. The guest who arrives half an hour too soon is the greatest nuisance. Some friends of my family had this irritating habit. The only thing to do was ask them to come half an hour later than the other guests. Then they arrived just when we wanted them. If you are citing a train, it is always better to be comfortably early than even a fraction of a minted too late. Although being early may mean wasting a little time, this will be less than if you miss the train and have to wait an hour or more for the next one; and you avoid the frustration
