假如科学家发现火星有生命英语作文
假如科学家发现火星有生命英语作文English Response:English Response:Discovering life on Mars would undoubtedly be one of the most significant scientific breakthroughs of our time. The implications would be staggering, not just for science but for humanity as a whole.Firstly, let's consider the scientific impact. Such a discovery would revolutionize our understanding of biology, astrobiology, and planetary science. It would provide crucial insights into the origins and evolution of life in the universe. Scientists would rush to study these Martian life forms, comparing them to life on Earth and seeking commonalities or differences. This could lead to breakthroughs in fields such as genetics, biochemistry, and evolutionary biology.Furthermore, the discovery would have profound philosophical and existential implications. For centuries, humans have wondered whether we are alone in the universe. Finding life on Mars would suggest that the universe is teeming with life, potentially even intelligent life. It would force us to confront our place in the cosmos and reconsider our understanding of life's purpose and meaning.Practically, the discovery would likely spur renewed interest and investment in space exploration. Governments, private companies, and research institutions would allocate resources to study Mars in greater detail, potentially paving the way for crewed missions to the Red Planet. This could kickstart a new era of space exploration and colonization, with Mars serving as a stepping stone for humanity's expansion into the solar system and beyond.On a more personal level, the discovery would capture the public's imagination like never before. People around the world would be fascinated by the idea of life beyond Earth, sparking discussions, debates, and speculation about what these Martian organisms might look like and how theymight behave. Science fiction authors would be inspired to write new stories exploring the implications of life on Mars, further fueling our collective imagination.In conclusion, the discovery of life on Mars would be a monumental moment in human history, with far-reaching consequences for science, philosophy, and society. It would inspire us to dream big and reach for the stars, reminding us of the boundless possibilities that await us in the cosmos.中文回答：如果科学家们发现了火星上存在生命，这无疑将是我们这个时代最重大的科学突破之一。
托福听力背景材料之地球之外的生命
托福听力背景材料之地球之外的生命Saturn's largest moon, Titan, has a thick atmosphere. Clouds. Complex organic molecules. NASA has called it "one of the most Earth-like worlds we have found to date." With one glaring exception. "It's awfully cold down there. It's about 94 degrees Kelvin. Which means that water would be a rock."土星最大的卫星是太阳神，太阳神有厚厚的大气层。
云是复杂的有机分子。
美国国家航空和宇宙航行局称它为“我们迄今为止发现的和地球最相似的星球”。
例外就是，这里特别冷。
温度在94凯市摄氏度，这就意味着水会被冻成坚硬的石头。
Paulette Clancy, a chemical engineer at Cornell University. At temperatures that cold —minus 290 degrees Fahrenheit—one of the most basic biological structures, the cell membrane, can't exist. Because to form, the oily membranes depend on the presence of liquid water.波莱特克兰西是康奈尔大学的一位化学工程师。
在温度为290华氏摄氏度时，最基本的细胞是不能存活的。
因为油膜的形成依赖于液态的水。
That said, Titan does have plenty of liquid to go around—but it's liquid methane. So Clancy and her colleagues used computer models to determine whether any molecules on Titan might mimic the membrane-forming compounds here on Earth. Based on a catalog of organics observed by NASA's Cassini mission, they found a candidate: acrylonitrile. Its internal electrical charge distribution would allow it to self-assemble into membranes, just like phospholipids do here on Earth. It's similarly flexible and stable. And there's a lot of it on Titan.据说太阳神这个星球上也有很多的液态物质，但这些是液态甲烷。

In o rder to obtain a licence to drive a taxi in London, candidates have to pass a detailed examination. They have to learn not only the streets, landmarks and hotels, but also the quickest way to get there. This is called “The Knowledge” by London Cab drivers and it can take years of study and practice to get ‘The Knowledge’. Candidates are examined not only onthe quickest routes but also on the quickest routes at different times of the day. People who want to pass the examination spend much of their free time driving or even cycling around London, studying maps and learning the huge street directory by heart.Passage 2: The UndergroundTravelling on the London underground (the ‘tube’) presents few difficulties for visitors because of the clear colour- coded maps. It is always useful to have plenty of spare change with you because there are often long queues at the larger stations. If you have enough change you can buy your ticket from a machine.

He knew every plant and stone in it, and he could swim across it easily. He was the biggest creature in the pond, so he was very important. When he croaked, the water-snails listened politely. And the water-beetles always swam behind him. He was very happy there.One day, while he was catching flies, a pretty dragon-fly passed by. ‘You’re a very fine frog,’ she sang, ‘but why don’t you live in a bigger pond? Come to my pond. You’ll find a lot of frogs there. You’ll meet some fine fish, and you’ 11 see the dangerous ducks. And you must see our lovely water-lilies. Life in a large pond is wonderful!’‘Perhaps it is rather dull here,’ thought the foolish frog. So he hopped after the dragon-fly.But he didn’t like the big, deep pond. It was full of strange plants. The water-snails were rude to him, and he was afraid of the ducks. The fish didn’t like him, and he was the smallest frog there. He was lonely and unhappy.He sat on a water-lily leaf and croaked sadly to himself, ‘I don’t like it here. I think I’ll go home tomorrow.’But a hungry heron flew down and swallowed him up for supper.Lesson 3Section ITask 1: I Don’t See It That WayA.Conversation 1:1.Choose the best answer for each of the following statements.(1) — (2): ba2.Give brief answers to the following questions.(1)About 6 months ago.(2)It is defective and has ruined 4 of the customer’s favorite cassettes.(3) 6 months.(4)10 days ago.3.Blank-filling.(1)bend the rule, make an exception for, make an exception for(2)adding insult to injury, make good on(3)brought it in, hold me to, onB.Conversation 2:1.Multiple choice.

Mo st people rarely think about how and why they sleep, however. We know that if we sleep well, we feel rested. If we don’t sleep enough, we often feel tired and irritable. It seems there are two purposes of sleep: physical rest and emotional and psychological rest: We need to rest our bodies and our minds. Both are important in order for us to be healthy. Each night we alternate between two kinds of sleep: active sleep and passive sleep. The passive sleep gives our body the rest that’s needed and prepares us for active sleep, in which dreaming occurs.Throughout the night, people alternate between passive and active sleep. The brain rests, then it becomes active, then dreaming occurs. The cycle is repeated: the brain rests, then it becomes active, then dreaming occurs. This cycle is repeated several times throughout the night~. During eight hours of sleep, people dream for a total d one and half hours on the average.Lesson 4Section ITask 1: Weather ForecastA.Multiple Choice. 1 — 2: acB.Fill in the following chart.Task 2: The 5 O’clock NewsA.Fill in the following chart.B.Give brief answers to the following questions based on the news report.1.It was closed down by government authorities.2.Testing confirmed that the town had been poisoned be the dumping of toxic chemicals in towndumps.3. 3 weeks ago.4.200.5.Headaches, stomachaches, faintness and dizziness.6.Toxic wastes had leaked into the ground and contaminated the water supply.7.All the residents should leave the area, until the chemical company responsible for the toxicwaste can determine whether the town can be cleaned up and made safe again.C.True of False Questions. 1—6: FTTFFTD.Fill in the following blanks (based on the news report).Teams Playing Result(1) Mexico — France 7 to 6(2) Canada — Argentina 3 to 3(3) Italy — Haiti2 to 1(with 30 minutes left to go)Section IITask 1: What Do You Like for Entertainment?A.Blank-filling.Reporter: Deborah TylerInterviewee: Students of the Brooklyn Academy of Dramatic ArtsMajor: Benny Gross —— pianoKimberley Martins —— modern danceB.Fill in the following chart about how often Benny and Kimberley go to the eight forms ofartistic entertainment.C.Rearrange the forms of artistic entertainment that Benny and Kimberley like, beginning withthe form that each one likes best.Benny: (3)—(1)—(4)—(6)—(2)—(8)Kimberley: (2)—(4)—(1)—(7)—(3)—(8)Task 2: Are You a Heavy Smoker?A.True or False Questions. 1—6: TFTTFTB.Multiple Choice. 1—6: cbcbacC.Blank-filling.Name: Doris BradleySex: femaleAge: 32Amount: 3 packets of 20 a weekFirst experience:Time: at the age of 17Place: at a partyOffered by: boyfriend, not husbandFeeling; awfully grown-upLater: started smoking 2 or 3 a day and gradually increased.Experience of giving up smoking: twice1.

It hasn’t changed in thirty years. The pupils were sitting in the same desks and reading the same books. When are schools going to move into the modern world? Books belong to the past. In our homes radio and television bring us knowledge of the world. We can see and hear the truth for ourselves. If we want entertainment most of us prefer a modern film to a classical novel. In the business world computers store information, so that we no longer need encyclopaedias and dictionaries. But in the schools teachers and pupils still use books. There should be a radio and televisionset in every classroom, and a library of tapes and records in every school. The children of today will rarely open a book when they leave school. The children of tomorrow won’t need to read and Write at all.M. P.

Here prediction is also based on common knowledge.Task 2: DictationThe School Holidays Are Too LongToday the children of this country have at last returned to work. After two months’ holiday pupils have started a new term. How many adults get such long holidays? Two to four weeks in the summer and public holidays--that’s all the working man gets. As for the average woman, she’s lucky to get a holiday at all. Children don’t need such long holidays. In term-time they start work later and finish earlier than anyone else.In the holidays most of them get bored, and some get into trouble. What a waste! If their overworked parents were given more free time instead, everyone would be happier.This isn’t just a national problem either--it’s worldwide.Dates may be different from country to country, but the pattern’s the same. Why should children do half as much work and get twice as much holiday as their parents?Lesson 6Section ITask 1: In the Path of the EarthquakeA.True or False Questions. 1—6: FTFTFFB.Map 1 is a layout of the Skinners’ farm.

Task 2: DictationSign LanguageDeaf people, people who can’t hear, are still able to communicate quite well with a special language. It’s called sign language.The speaker of sign language uses hand gestures in order to communicate. Basic sign language has been used for a long, long time, but sign language wasn’t really developed until about 250 years ago. In the middle of the 1700s a Frenchman named Epée developed sign language. Epée was able to speak and hear, but he worked during most of his life as a teacher of deaf people in France. Epée developed a large number of vocabulary words for sign language. Epée taught these words to his deaf students. Epée’s system used mostly picture :image signs. We call them picture image signsbecause the signs create a picture. For example, the sign for sleep is to put both hands together, and then to place the hands flat against the right side of your face, and then to lower your head slightly to the right. This action was meant to show the position of sleep. So we call it a picture image sign.Lesson 7Section ITask 1: Learning a Foreign LanguageA.Multiple Choice. 1—4: bcaaB.True or False Questions. 1—4: FTTFC.Give brief answers to the following questions.1.Albert Humphries.2.Balham, London.3. 4 years.4.He has been going to an evening class and has watched quite a lot of the BBC televisionprogrammes.5.They use a different book in the class.6.They make the same mistakes as he does.7.It means being able to put together the right groups of words and to say them in a reasonablyaccurate way.Task 2: In the LibraryA.Multiple Choice. 1—6: bbcacaB.True or False Questions. 1—6: TTFTFTC.Give brief answers to the following questions.1.Round the corner.2.

To escape the inevitable doom, mankind devises a bold plan: to build thousands of engines on the surface of the planet and push it out of the solar system, hoping to find a new home among the stars. This is the premise of the science fiction thriller "The Wandering Earth," a film that takes us on a thrilling journey through space and time.The story revolves around the Liu family, who arecaught in the midst of this grand scheme. Liu Qi, a young man, dreams of a life beyond the engines and the constant danger of space debris. However, when the Earth is threatened by a collision with a nearby asteroid belt, heis forced to abandon his dreams and join the mission tosave the planet. Alongside his father, Liu Peiqiang, a former truck driver and now a key member of the rescue team, they embark on a perilous mission to detonate the asteroids and save the Earth.The film is a testament to the resilience and unity of mankind in the face of existential crisis. Despite their differences and conflicts, the Liu family and the rest of the world unite to face the common enemy: the impending doom of the solar system.

1、Finding Life Beyond Earth 寻找地球以外的生命Since early times, people have been fascinated with the idea of life existing somewhere else besides earth. Until recently, scientists believed that life on other planets was just a hopeful dream. But now they are beginning to locate places where life could form.很久以来，人们就被地球以外存在生命的观点强烈地吸引。
直到近期，科学家们都坚信外星生命的想法只不过是个有希望的梦想。
但是现在他们开始定位外星生命形成的位置。
In 1997, they saw evidence of planets near other stars like the sun. But scientists now think that life could be even nearer in our own solar system. One place scientists are studying very closely is Europa, a moon of Jupiter.在1997年，他们在像太阳这类其他恒星的行星上发现了证据。
可是，现在科学家认为外星生命甚至更接近我们，就存在于我们太阳系中。
科学家们正在仔细研究的这个地方是欧罗巴，是木星的卫星。
Space probes have provided evidence that Europa has a large ocean under its surface. The probes have also made scientists think that under its surface Europa has a rocky core giving off volcanic heat. Water and heat from volcanic activity are two basic conditions needed for life to form.太空探索提供的证据表明在欧罗巴的表层下蕴藏着一个巨大的海洋。
太空探索还使科学家们相信在欧罗巴的表层下有一个岩层核心，释放出火山般的热量。
火山活动的水和热是生命形式所需的两个基本条件。
A third is certain basic chemicals such as carbon, oxygen and nitrogen. Scientists believe there might be such chemicals lie at the bottom of Europa's ocean.They may have already created life or may be about to. You may wonder if light is also needed for life to form. Until recently, scientists thought that light was essential.第三个条件是某些基本的化学元素，如：碳、氧、氮。
科学家相信在欧罗巴的海底可能存在这些物质。
它们或许已经创造了生命，也许将来会产生生命。
你或许想知道光对于生命的形成是否必要。
直到最近，他们都认为光是必须的。
But now, places have been found on earth that are in total blackness such as caves several miles beneath the surface. And bacteria, primitive forms of life have been seen there. So the lack of light in Europa's sub-surface ocean doesn't automatically rule out life forming.但是，现在地球上完全黑暗的地方也有生命，如在地表下数公里的洞穴中。
生命原始形式的细菌就存在于那儿。
因此，在欧罗巴表层以下缺少阳光的海洋中无法自动排除生命存在的可能。

2、How to Stop Global Warming 如何阻止全球变暖Global warming may or not be the great environmental crisis of the 21st century, but—regardless of weather it is or isn't—we won't do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.全球变暖有可能是21世纪巨大的环境危机，也有可能不是，但是无论它是或不是我们对此都无能为力。
我们会争论不休，作为一个国家，或许会做出一些听起来相当认真的承诺来避免这一危机。
但是这些承诺看起来越是令人印象深刻、越是有意义，就越是不太可能被遵守。
Al Gore calls global warming an “inconvenient truth,”as if merely recognizing it could put in on a path to a solution. Butthe real truth is that we don't know enough to believe global warming, and —with our major technological breakthroughs —we can't do much about it.Al Gore 称全球变暖是一个“让人感到麻烦的事实”，似乎只要认识到它的存在就可以把我们带往一条解决问题的途经上去。
但是真正的事实是，我们没有掌握足够的知识去缓解全球变暖，并且如果没有重大的技术突破，我们对此也束手无策。
No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel)that might cut back global warming. Still, politicians want to show they're “doing something”. Consider the Kyoto Protocol. It allowed countries that joined to punish those that didn't. But it hasn't reduced CO? emissions (up about 25% since 1990), and many signatories didn't adopt tough enough policies to hit their 2008 —2012 targets.没有哪个政府会对经济增长和个人自由(限制电力的使用，驾驶和旅游)采取严格的限制令，虽然这样的限制可以缓解全球变暖。
