Introduction:Throughout human history, the idea of extraterrestrial life has captured our imagination. Countless stories, movies, and scientific inquiries have been dedicated to the possibility of encountering beings from beyond our planet. While some dismiss the notion as mere fiction, othersremain fascinated by the idea. In this essay, we will explore the concept of extraterrestrial beings, drawing inspiration from popular depictions and scientific theories.Body:1. The Fascination with Extraterrestrial Life:Humans have always looked to the stars with wonderand curiosity. From ancient civilizations to modern astronomers, the search for life beyond Earth has been a driving force in our exploration of the cosmos. The idea that we are not alone in the universe ignites our imagination and pushes the boundaries of what we know.2. The Search for Extraterrestrial Intelligence (SETI):Scientists have been actively searching for signs of extraterrestrial intelligence through programs like SETI. By scanning the skies for radio signals or other anomalies, researchers hope to detect evidence of civilizations beyond our own. While no conclusive proof has been found yet, the quest continues, fueled by the belief that we may one day make contact with another intelligent species.3. Popular Depictions of Extraterrestrial Beings:In literature, movies, and television, extraterrestrial beings are a common theme. From friendly aliens like E.T. to menacing invaders like those in "War of the Worlds," these portrayals reflect our hopes, fears, andimaginations. While some depictions are purely entertainment, others provoke deeper questions about our place in the universe and our relationship with other forms of life.4. Scientific Theories About Extraterrestrial Life:Scientists have put forward various theories about where and how extraterrestrial life might exist. Some focus on planets within our own solar system, such as Mars or Europa, where conditions could be conducive to life. Others look to distant exoplanets orbiting other stars, speculating about the potential for habitable environments beyond our solar neighborhood. While much remains unknown, ongoing research continues to expand our understanding of the possibilities.5. The Implications of Contact:The prospect of making contact with extraterrestrial beings raises profound questions and challenges for humanity. How would such an encounter impact our society,our beliefs, and our understanding of ourselves? Would it unite us as a species or divide us along cultural, religious, or political lines? These are complex issues that have been explored in science fiction and debated by scholars and ethicists.Conclusion:While the idea of encountering extraterrestrial beings may seem like science fiction, it remains a tantalizing possibility that captivates our imagination and drives scientific inquiry. Whether through the search for signals from distant civilizations or the exploration of potentially habitable worlds, humanity continues to reach for the stars in search of answers to one of our most profound questions: are we alone in the universe?。
Was Einstein a Space Alien原文及翻译
Was Einstein a Space Alien原文及翻译Was Einstein a Space Alien原文及翻译原文:Albert Einstein, one of the greatest minds in the history of science, is known for his groundbreaking theories and contributions to the field of physics. However, there have been persistent rumors and speculations that Einstein was more than just a brilliant scientist – some believe that he may have been a space alien. This article delves into the evidence, myths, and theories surrounding the idea that Einstein was a visitor from outer space.Einstein was born on March 14, 1879, in Ulm, Germany. From a young age, he showed a profound interest in mathematics and physics. His exceptional intellect and ability to think outside the box allowed him to develop revolutionary concepts, such as the theory of relativity. However, some people argue that his extraordinary abilities were not entirely human in origin.One theory suggests that Einstein's incredible intelligence and revolutionary ideas were the result of extraterrestrial intervention. According to proponents of this hypothesis, Einstein's ideas were too advanced for a mere mortal and could only have come from a more advanced civilization. They speculate that Einstein was a vessel for extraterrestrial knowledge, sent to Earth to enlighten humanity.Another aspect often pointed out is Einstein's physical appearance. Some claim that his distinctive features, such as his wild hair and intense gaze, resemble the stereotypical image of aliens depicted in popular culture. This has led some to believe that Einstein's appearance was evidence of his extraterrestrial origin.Additionally, skeptics argue that Einstein's breakthroughs in science were too unconventional to have been achieved through purely human means. They suggest that his insights into the nature of space and time were the result of otherworldly guidance. Some even go as far as suggesting that he had access to advanced technology and knowledge that had been shared by extraterrestrial beings.Despite these compelling arguments, it is important to approach these theories with a skeptical mind. The idea that Einstein was an alien lacks solid evidence and is largely based on speculation. While his intellect and contributions to science were undoubtedly extraordinary, they can be explained by his own brilliance and dedication to his work.翻译:艾因斯坦是太空外星人吗？艾因斯坦是科学史上最伟大的思想家之一，以他的开创性理论和对物理学领域的贡献而闻名。

剑桥雅思阅读9原文(test1)READING PASSAGE 1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.William Henry PerkinThe man who invented synthetic dyesWilliam Henry Perkin was born on March 12, 1838, in London, England. As a boy, Perkin’s curiosity prompted early intere sts in the arts, sciences, photography, and engineering. But it was a chance stumbling upon a run-down, yet functional, laboratory in his late grandfather’s home that solidified the young man’s enthusiasm for chemistry.As a student at the City of London School, Perkin became immersed in the study of chemistry. His talent and devotion to the subject were perceived by his teacher, Thomas Hall, who encouraged him to attend a series of lectures given by the eminent scientist Michael Faraday at the Royal Institution. Those speeches fired the young chemist’s enthusiasm further, and he later went on to attend the Royal College of Chemistry, which he succeeded in entering in 1853, at the age of 15.At the time of Perkin’s enrolment, the Royal College of Chemistry was headed by the noted German chemist August Wilhelm Hofmann. Perkin’s scientific gifts soon caught Hofmann’s attention and, within two years, he becameHofmann’s youngest assistant. Not long after that, Perkin made the scientific breakthrough that would bring him both fame and fortune.At the time, quinine was the only viable medical treatment for malaria. The drug is derived from the bark of the cinchona tree, native to South America, and by 1856 demand for the drug was surpassing the available supply. Thus, when Hofmann made some passing comments about the desirability of a synthetic substitute for quinine, it was unsurprising that his star pupil was moved to take up the challenge.During his vacation in 1856, Perkin spent his time in the laboratory on th e top floor of his family’s house. He was attempting to manufacture quinine from aniline, an inexpensive and readily available coal tar waste product. Despite his best efforts, however, he did not end up with quinine. Instead, he produced a mysterious dark sludge. Luckily, Perkin’s scientific training and nature prompted him to investigate the substance further. Incorporating potassium dichromate and alcohol into the aniline at various stages of the experimental process, he finally produced a deep purple solution. And, proving the truth of the famous scientist Louis Pasteur’s words ‘chance favours only the prepared mind’, Perkin saw the potential of his unexpected find.Historically, textile dyes were made from such natural sources as plants and animal excretions. Some of these, such as the glandular mucus of snails, were difficult to obtain and outrageously expensive. Indeed, the purple colour extracted from a snail was once so costly in society at the time only the rich could afford it. Further, natural dyes tended to be muddy in hue and fade quickly. It was against this backdrop that Perkin’sdiscovery was made.Perkin quickly grasped that his purple solution could be used to colour fabric, thus making it the world’s first synthetic dye. Realising the importance of this breakthrough, he lost no time in patenting it. But perhaps the most fascinating of all Perkin’s reactions to his find was his nearly instant recognition that the new dye had commercial possibilities.Perkin originally named his dye Tyrian Purple, but it later became commonly known as mauve (from the French for the plant used to make the colour violet). He asked advice of Scottish dye works owner Robert Pullar, who assured him that manufacturing the dye would be well worth it if the colour remained fast (i.e. would not fade) and the cost was relatively low. So, over the fierce objections of his mentor Hofmann, he left college to give birth to the modern chemical industry.With the help of his father and brother, Perkin set up a factory not far from London. Utilising the cheap and plentiful coal tar that was an almost unlimited byproduct of London’s gas street lighting, the dye works began producing the world’s first synthetically dyed material in 1857. The company received a commercial boost from the Empress Eugenie of France, when she decided the new colour flattered her. Very soon, mauve was the necessary shade for all the fashionable ladies in that country. Not to be outdone, England’s Queen Victoria also appeared in public wearing a mauve gown, thus making it all the rage in England as well. The dye was bold and fast, and the public clamoured for more. Perkin went back to the drawing board.Although Perkin’s fame was achieved and fortune assured by his first discovery, the chemist continued his research. Among other dyes he developed and introduced were aniline red (1859)and aniline black (1863) and, in the late 1860s, Perkin’s green. It is important to note that Perkin’s synthetic dye discoveries had outcomes far beyond the merely decorative. The dyes also became vital to medical research in many ways. For instance, they were used to stain previously invisible microbes and bacteria, allowing researchers to identify such bacilli as tuberculosis, cholera, and anthrax. Artificial dyes continue to play a crucial role today. And, in what would have been particularly pleasing to Perkin, their current use is in the search for a vaccine against malaria.Questions 1-7Do the following statements agree with the information given in Reading Passage 1?In boxes 1-7 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this1 Michael Faraday was the first person to recognise Perkin’s ability as a student of chemistry.2 Michael Faraday suggested Perkin should enrol in the Royal College of Chemistry.3 Perkin employed August Wilhelm Hofmann as his assistant.4 Perkin was still young when he made the discovery that made him rich and famous.5 The trees from which quinine is derived grow only in South America.6 Perkin hoped to manufacture a drug from a coal tar waste product.7 Perkin was inspired by the discoveries of the famous scientist Louis Pasteur.Questions 8-13Answer the questions below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 8-13 on your answer sheet.8 Before Perkin’s discovery, with what group in society was the colour purple associated?9 What potential did Perkin immediately understand that his new dye had?10 What was the name finally used to refer to the first colour Perkin invented?11 What was the name of the person Perkin consulted before setting up his own dye works?12 In what country did Perkin’s newly invented colour first become fashionable?13 According to the passage, which disease is now being targeted by researchers using synthetic dyes?READING PASSAGE 2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 on the following pages.Questions 14-17Reading Passage 2 has five paragraphs, A-E.Choose the correct heading for paragraphs B-E from the list of headings below.Write the correct number, i-vii, in boxes 14-17 on your answer sheet.List of Headingsi Seeking the transmission of radio signals from planetsii Appropriate responses to signals from other civilisations iii Vast distances to Earth’s closest neighboursiv Assumptions underlying the search for extra-terrestrial intelligencev Reasons for the search for extra-terrestrial intelligencevi Knowledge of extra-terrestrial life formsvii Likelihood of life on other planetsExample AnswerParagraph A v14 Paragraph B15 Paragraph C16 Paragraph D17 Paragraph EIS THERE ANYBODY OUT THERE?The Search for Extra-terrestrial IntelligenceThe question of whether we are alone in the Universe has haunted humanity for centuries, but we may now stand poised on the brink of the answer to that question, as we search for radio signals from other intelligent civilisations. This search, often known by the acronym SETI (search for extra-terrestrial intelligence), is a difficult one. Although groups around the world have been searching intermittently for three decades, it is only now that we have reached the level of technology where we can make a determined attempt to search all nearby stars for any sign of life.AThe primary reason for the search is basic curiosity hethe same curiosity about the natural world that drives all pure science. We want to know whether we are alone in the Universe. We want to know whether life evolves naturally if given the right conditions, or whether there is something very special about the Earth to have fostered the variety of life forms that, we seearound us on the planet. The simple detection of a radio signal will be sufficient to answer this most basic of all questions. In this sense, SETI is another cog in the machinery of pure science which is continually pushing out the horizon of our knowledge. However, there are other reasons for being interested in whether life exists elsewhere. For example, we have had civilisation on Earth for perhaps only a few thousand years, and the threats of nuclear war and pollution over the last few decades have told us that our survival may be tenuous. Will we last another two thousand years or will we wipe ourselves out? Since the lifetime of a planet like ours is several billion years, we can expect that, if other civilisations do survive in our galaxy, their ages will range from zero to several billion years. Thus any other civilisation that we hear from is likely to be far older, on average, than ourselves. The mere existence of such a civilisation will tell us that long-term survival is possible, and gives us some cause for optimism. It is even possible that the older civilisation may pass on the benefits of their experience in dealing with threats to survival such as nuclear war and global pollution, and other threats that we haven’t yet discovered.BIn discussing whether we are alone, most SETI scientists adopt two ground rules. First, UFOs (Unidentified Flying Objects) are generally ignored since most scientists don’t consider the evidence for them to be strong enough to bear serious consideration (although it is also important to keep an open mind in case any really convincing evidence emerges in the future). Second, we make a very conservative assumption that we are looking for a life form that is pretty well like us, since if it differs radically from us we may well not recognise it as a life form,quite apart from whether we are able to communicate with it. In other words, the life form we are looking for may well have two green heads and seven fingers, but it will nevertheless resemble us in that it should communicate with its fellows, be interested in the Universe, live on a planet orbiting a star like our Sun, and perhaps most restrictively, have a chemistry, like us, based on carbon and water.CEven when we make these assumptions, our understanding of other life forms is still severely limited. We do not even know, for example, how many stars have planets, and we certainly do not know how likely it is that life will arise naturally, given the right conditions. However, when we look at the 100 billion stars in our galaxy (the Milky Way), and 100 billion galaxies in the observable Universe, it seems inconceivable that at least one of these planets does not have a life form on it; in fact, the best educated guess we can make, using the little that we do know about the conditions for carbon-based life, leads us to estimate that perhaps one in 100,000 stars might have a life-bearing planet orbiting it. That means that our nearest neighbours are perhaps 100 light years away, which is almost next door in astronomical terms.DAn alien civilistation could choose many different ways of sending information across the galaxy, but many of these either require too much energy, or else are severely attenuated while traversing the vast distances across the galaxy. It turns out that, for a given amount of transmitted power, radio waves in the frequency range 1000 to 3000 MHz travel the greatest distance, and so all searches to date have concentrated on looking forradio waves in this frequency range. So far there have been a number of searches by various groups around the world, including Australian searches using the radio telescope at Parkes, New South Wales. Until now there have not been any detections from the few hundred stars which have been searched. The scale of the searches has been increased dramatically since 1992, when the US Congress voted NASA $10 million per year for ten years to conduct, a thorough search for extra-terrestrial life. Much of the money in this project is being spent on developing the special hardware needed to search many frequencies at once. The project has two parts. One part is a targeted search using the world’s largest radio telescopes, the American-operated telescope in Arecibo, Puerto Rico and the French telescope in Nancy in France. This part of the project is searching the nearest 1000 likely stars with high sensitivity for signals in the frequency rang 1000 to 3000 MHz. The other part of the project is an undirected search which is monitoring all of space with a lower sensitivity, using the smaller antennas of NASA’s Deep Space Network.EThere is considerable debate over how we should react if we detect a signal from an alien civilisation. Everybody agrees that we should not reply immediately. Quite apart from the impracticality of sending a reply over such large distances at short notice, it raises a host of ethical questions that would have to be addressed by the global community before any reply could be sent. Would the human race face the culture shock if faced with a superior and much older civilisation? Luckily, there is no urgency about this. The stars being searched are hundreds of light years away, so it takes hundreds of years for their signal toreach us, and a further few hundred years for our reply to reach them. It’s not important, then, if there’s a delay of a few years, or decades, while the human race debates the question of whether to reply, and perhaps carefully drafts a reply.Questions 18-20Answer the questions below.Choose NO MORE THAN THREE WORDS AND/OR A NUMBER from the passage for each answer.Write your answers in boxes 18-20 on your answer sheet.18 What is the life expectancy of Earth?19 What kind of signals from other intelligent civilisations are SETI scientists searching for?20 How many stars are the world’s most powerful radio telescopes searching?Questions 21-26Do the following statements agree with the views of the writer in Reading Passage 2?In boxes 21-26 on your answer sheet, writeYES if the statement agrees with the views of the writerNO if the statement contradicts the views of the writerNOT GIVEN if it is impossible to say what the writer thinks about this21 Alien civilisations may be able to help the human race to overcome serious problems.22 SETI scientists are trying to find a life form that resembles humans in many ways.23 The Americans and Australians have co-operated on joint research projects.24 So far SETI scientists have picked up radio signals from several stars.25 The NASA project attracted criticism from some members of Congress.26 If a signal from outer space is received, it will be important to respond promptly.READING PASSAGE 3You should spend about 20 minutes on Questions 27-40, which are based on Reading Passage 3 below.The history of the tortoiseIf you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn’t forget the pla nts, without whose prior invasion of the land none of the other migrations could have happened.Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thorough going land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales (including the small whales we call dolphins) and dugongs, with their close cousins the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don’t even come ashoreto breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches.There is evidence that all modern turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Plaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modern turtles and tortoises. You might wonder how we can tell whether fossil animals lived on land or in water, especially if only fragments are found. Sometimes it’s obvious. Ichthyosaurs were reptilian contemporaries of the dinosaurs, with fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs.Walter Joyce and Jacques Gauthier, at Yale University, obtained three measurements in these particular bones of 71 species of living turtles and tortoises. They used a kind of triangular graph paper to plot the three measurements against one another. All the land tortoise species formed a tight cluster of points in the upper part of the triangle; all the water turtles cluster in the lower part of the triangular graph. There was no overlap, except when they added some species that spend time both in water and on land. Sure enough, these amphibious species show up on the triangular graph approximately half way between the ‘wet cluster’ of sea turtles and the ‘dry cluster’of land tortoises. The next step was to determine where the fossils fell. The bones of P. quenstedti and P. talampayensis leave us in no doubt. Their points on the graph are right in the thick of the dry cluster. Both these fossils were dry-land tortoises. They come from the era before our turtles returned to the water.You might think, therefore, that modern land tortoises have probably stayed on land ever since those early terrestrial times, as most mammals did after a few of them went back to the sea. But apparently not. If you draw out the family three of all modern turtles and tortoises, nearly all the branches are aquatic. Today’s land tortoises constitute a single branch, deeply nested among branches consisting of aquatic turtles. This suggests that modern land tortoises have not stayed on land continuously since the time of P. quenstedti and P. talampayensis. Rather, their ancestors were among those who went back to the water, and they then reemerged back onto the land in (relatively) more recent times.Tortoises therefore represent a remarkable double return. In common with all mammals, reptiles and birds, their remote ancestors were marine fish and before that various more or less worm-like creatures stretching back, still in the sea, to the primeval bacteria. Later ancestors lived on land and stayed there for a very large number of generations. Later ancestors still evolved back into the water and became sea turtles. And finally they returned yet again to the land as tortoises, some of which now live in the driest of deserts.Questions 27-30Answer the questions below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 27-30 on your answer sheet.27 What had to transfer from sea to land before any animals could migrate?28 Which TWO processes are mentioned as those in which animals had to make big changes as they moved onto lands?29 Which physical feature, possessed by their ancestors, do whales lack?30 which animals might ichthyosaurs have resembled?Questions 31-33Do the following statements agree with the information given in Reading Passage 3?In boxes 31-33 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this31 Turtles were among the first group of animals to migrate back to the sea.32 It is always difficult to determine where an animal lived when its fossilised remains are incomplete.33 The habitat of ichthyosaurs can be determined by the appearance of their fossilised remains.Questions 34-39Complete the flow-chart below.Choose NO MORE THAN TWO WORDS AND/OR A NUMBER from the passage for each answer.Write your answers in boxes 34-39 on your answer sheet.Method of determining where the ancestors of turtles and tortoises come fromStep 171 species of living turtles and tortoises were examined anda total of 34 ……………………. were taken from the bones of theirforelimbs.Step 2The data was recorded on a 35 ………………..

Since human beings have existed in the Earth for millions of years, some scientists are curious about other intelligent forms in the universe. Some scientists attempt to municate with these life forms. However, others believe it would be hazardous. In the following essay, both views will be explored as well as my personal stance.On one hand, many scientists and evidence has proved that humans are definitely not the only creature in theuniverse, so contacting these intelligent life forms could be demanding. Specifically, other life forms also existedon other plas; some of them even have visited the Earth.For example, about several decades ago, an UFO has visiteda small town of America, and they did not attack the humans. They could have destroyed the Earth if they had despicable plans. Therefore, contacting with these unknown creatures could help us to know the outer space better, so it wouldbe beneficial for the humans to try to contact with these aliens.In stark contrast, some other scientists believe that contacting with life forms would bring danger to the humans because we barely know them. To be precise, some scientists believe that these intelligent life forms could be smarter than us, and have more advanced technologies, people cannot win the war if they invade the Earth. Take films as example, as it describes in Independence Day, aliens invaded the Earth as they were aiming at the sufficient natural resources on earth and it is totally for their own interest. Their attack caused huge damage to the earth as humanbeings have no advanced weapon to fight back.In my opinion, even getting in touch with aliens could bring dangers to humans, it is still worth trying as I believe the majority of them are seeking for peace of the whole universe and hostility is barely carried. Looking forother creatures in the vast universe is a big step for humans to explore the outer space. It could be a double-sword, bringing both opportunities and challenges. Whether aliens are dangerous dose not truly matter under this circumstance, what is more important is that earthman, us, have the ability and courage to take adventures in the unknown space and meet something new.With advancement of societal technology, certain scientists work for looking for other intelligent life forms who may not exist on the earth such as aliens. While some people argue that contacting with them is likely to bring danger to human. Therefore, the essay aims to critically discuss both views and e up with my own opinion.That a number of researchers try to find other plas’ living species has to be admitted that pursing that curiosity is one of mankind’s nature. Additionally, by exchanging ideas with aliens about historical progression and ac ademic discussion and so on, mankind’s world has the opportunity to make immense progress in modern technology by giving inspirations to scientists for pushing the frontiers of science which may solve particular thorny issues such as environmental pollution. On the other hand, as far as some researchers are concerned, it lays a solid foundation for people to possess an improved quality oflife who live on other plas in order to avoid diseases anddisasters brought by serve atmosphere pollution and doomsday respectively.While, simultaneously, others claim that touching with aliens probably breaks seemingly peaceful earth and brings unexpected danger. Firstly, it is likely that being greedy, exploitative and violent, aliens are searching for somewhere to harvest for water, minerals and fuel, contributing to meeting unprecedented risk by telling them the man’s existence. Furthermore, people know nothing of extraterrestrial intelligence intentions and capabilities so it is impossible to predict whether they will be benign or hostile. For example, earthlings will may be slaughtered and enslaved as colonized countries in the past time.From a personal perspective, earthlings can try to search for other unique life forms in various plas, but without promising to guarantee human’s lives, it would not better send messages to aliens and disturb their daily lives.Our imagination about beings on other plas has never stopped and reached its climax in such movie series like “Star Wars” and “Star Trek” in 1960s and 1970s. If other life forms do exist, an idea I strongly support, should we, as human beings on the Earth, try to reach out and municate with them?A lot of people do not like the idea of sending messages to aliens “out there”. Aording to their theory, trying to establish munication with other life forms is extremely expensive because it entails designing plex equipment and apparatus. This will consume tons of money, which should be spent solving more practical problems like medical care or education. More importantly, as these people would claim, once they receive our messages and know about our existence, the aliens may invade the Earth and eliminate us all, just like what they do in many movies and science fiction.There are others who are very enthusiastic about reaching out for aliens on other plas. They are interested in how these different life forms survive and believe their more advanced technology may well help us human beings solve our existent problems. Having been living in the universe as the only intelligent being for too long, many people find it very attractive to reach their brothers and sisters from other plas. It is significant for another reason, too. As the Earth will surely die and disappearinto the black hole as many scientists have speculated, we need to be known by our siblings on other plas so that when that day eventually does e, our future grand, grandchildren will not perish.Personally, I do not think much of the “danger” theory. If the aliens are less developed than us, they cannot be a threat to us even if they want to; if they are more developed and civilized, the probability that we are killed by them is still lower. Once the xenophobic danger is removed, I believe most of us will wele the idea of municating with the intelligent forms outside the Earth, because they can provide us with the much desired panionship and may save us when the Earth expires.When it es to the issue about the possibility of aliens’ existence on other plas, some people argue that there should be munication between human beings and other creatures if they really exist, but others believe that it may lead to some potential risks for human beings to municate with unknown life forms.On one hand, mankind may benefit from municating with other creatures if they own advanced technologies. It is true that human beings have developed numerous technologies currently, but some aspects, such as space exploration,still need to be improved. If other plas possess technologies human beings do not have, maybe they could assist us to make a progress. Thus, sending messages to them could allow human beings to have more technologies from the universe possibly.On the other hand, getting in touch with aliens may be detrimental to human beings since they may invade the earth. Countries on the earth will fight with each other because they need to acquire more resources. Similarly, if alien civilization also intended to reap some profits from the earth, space wars would be an inevitable consequence. Therefore, in order to maintain a peaceful life on the earth, human beings should be really cautious about sending messages to outer space.From my own perspective, exploring space will be a pulsory task for mankind sooner or later, but scientists should be patient before they make more breakthroughs.After all, human beings are just potent to send their astronauts into outer space for limited time and our technology is still not so mature. Also, there still exist all kinds of conflicts among countries on the earth and developing domestic economy should be the top priority for most governments to improve their citizens’ life quality. Thus, human beings may not be prepared to wele alien civilization in the current era.。

TEST 1 PASSAGE 2 参考译文：外星有生命存在吗?——搜寻外星文明计划人类是否是宇宙中唯一存在的生命这个问题已经困扰我们几百年了，然而随着搜索来自其他智慧文明的无线电信号，现在我们或许离这个问题的答案已经不远了。
这项也被称为SETI (search for extra?terrestrial intelligence, 搜寻外星文明)的计划进行起来非常困难。
虽然世界各地的团体已经断断续续地搜寻了三十多年，然而直到现在，我们所达到的技术水平才允许我们下定决心去尝试搜寻附近所有附近星球上的任何生命迹象。
A 人类之所以搜索无线电信号，主要是出于一种基本的好奇心，正是这种对大自然的好奇心推动了所有纯科学的发展。
我们想知道人类是否是宇宙中唯一存在的生命。
我们想知道在适宜的条件下，生命是否会自然形成。
我们还想知道地球上是否存在某种特殊的物质，孕育了那些我们司空见惯的各种形式的生命体。
只需监测一下无线电信号，这些最根本的问题就能够得到充分解答。
从这种意义上来说，SETI 是纯科学系统发展的又一个重要推动力，而纯科学正不断拓宽着人类的知识范围。
然而，人类之所以对其他地方是否存在生命这件事感兴趣，还有其他原因。
比如，我们地球上的文明历史只有寥寥数千年，而过去几十年的核战争与污染的威胁告诉人类，我们的生命也许很脆弱。
我们还能再延续两千年吗?还是将自我灭绝呢?既然像地球这样的星球拥有数十亿年的寿命，我们可以猜想，如果银河系中确实还有其他文明存在，那么它们的历史可能从零到数十亿年不等。
因此，如果我们收到其他文明的信号，那它们的平均历史很有可能比人类历史长得多。

外星人科幻英语作文Title: Encounters with Extraterrestrial Intelligence.In the vastness of the universe, the existence of extraterrestrial life is a concept that has fascinated and perplexed humanity for centuries. The idea of intelligent beings beyond our planet has been explored through various scientific, cultural, and fictional mediums, each offering unique perspectives on this enigmatic subject. As we delve deeper into the mysteries of the cosmos, the question remains: are we alone in this infinite expanse of space and time?The search for extraterrestrial intelligence (ETI) has been a central theme in the scientific community for decades. Projects like SETI (Search for Extraterrestrial Intelligence) have been scanning the cosmos for signs of intelligent life, utilizing radio telescopes and other advanced technologies to intercept any potential signals. While no conclusive evidence of extraterrestrial life hasbeen found, the quest continues, fueled by curiosity andthe desire to understand our place in the universe.The concept of extraterrestrial life has also been a staple in science fiction literature and cinema. From the classic H.G. Wells' novel "The War of the Worlds" to modern blockbusters like "Star Wars" and "Alien," these narratives offer a window into the possibilities of extraterrestrial encounters. They range from terrifying encounters withalien predators to hopeful collaborations with benevolent beings, each scenario painting a unique picture of what an extraterrestrial encounter might look like.But what would an actual encounter withextraterrestrial intelligence look like? Would we even be able to comprehend the nature of their intelligence, given the vast differences in biology, culture, and technology? Would such an encounter bring about a new era of scientific understanding or would it present a threat to our existence?The potential impact of extraterrestrial contact is immense. It could rewrite our understanding of life, theuniverse, and everything. It could provide answers to the fundamental questions about our existence, such as the origin of life and the purpose of consciousness. On the other hand, it could also pose significant risks, such as the potential for conflict or the spread ofextraterrestrial diseases.As we continue to explore the universe and push the boundaries of scientific knowledge, the question of extraterrestrial life remains an intriguing and complex topic. Whether we encounter extraterrestrial intelligence in the near future or not, the pursuit of knowledge and understanding will remain a critical aspect of human civilization.In conclusion, the search for extraterrestrial intelligence is a journey that spans the boundaries of science, culture, and imagination. It is a quest that challenges our understanding of the universe and our place within it. As we continue to explore and learn, we must remain open to the possibilities that lie beyond our current understanding. Perhaps one day, we will find theanswer to the ultimate question: are we alone in the universe? Until then, the search for extraterrestrial intelligence will remain a fascinating and essential aspect of human endeavor.。

智慧外星人extraterrestrial intelligence
Renowned physicist Stephen Hawking and Russian billionaire Yuri Milner are pushing the search for extraterrestrial life into higher gear. The pair said Monday the $100m program funded by Milner will combine unprecedented computing capacity with the world's most powerful telescopes in a search of the heavens. Milner said the search will be entirely transparent and will rely on open-source software so findings can be shared throughout the world.
著名物理学家史蒂芬·霍金和俄罗斯亿万富豪尤里·米尔纳的联合将外星人搜索推向了一个全新的高度。
两人20日透露，将由米尔纳出资1亿美元，以前所未有的方式充分利用计算机技术和世界上最强大的望远镜，开启太空搜寻。
米尔纳表示，搜寻将全程透明，且使用开源软件，保证最终的发现成果由全世界共享。
外星人用英文表示可以是alien，这个词也有外国人、陌生的等含义。
此外上文中的extraterrestrial life可以表示外星生命，这是个天文学名词。
ET也可以表示外星人，是extraterrestrial的缩写。
智慧外星人即extraterrestrial intelligence。
此次寻找外星人计划的英文为search for extraterrestrial intelligence，简称SETI。
在此次伦敦皇家科学学会寻找外星生命迹象的启动仪式上，霍金说：“在无限的茫茫宇宙中(in an infinite universe)，一定存在着其它形式的生命( other occurrences of life)。
或许外星生命会正盯着我们看呢。
不管怎样，这都是最重要的问题。
是时候有人来找出这个问题的答案了，去寻找地球以外的生命(search for life beyond Earth)。
弄清楚我们到底是不是黑暗中孤独的存在，这点对我们很重要。
”。
