It's a question that has fascinated humans for centuries, and one that we may never know the answer to for sure. But there are some tantalizing clues that suggest that we may not be alone in the universe.One of the most important factors in determining whether a planet can support life is its distance from its star. A planet that is too close to its star will be too hot for liquid water to exist on its surface, while a planet that is too far away will be too cold. Earth is located in the "habitable zone" of our solar system, which means that it is just the right distance from the sun to support liquid water.Another important factor is the presence of a thick atmosphere. An atmosphere helps to regulate a planet's temperature and protect it from harmful radiation. Earth's atmosphere is made up of a mixture of gases, including nitrogen, oxygen, and carbon dioxide. These gases help to keep Earth's surface temperature relatively stable and protect us from the sun's harmful rays.Of course, the most important factor in determining whether a planet can support life is the presence of water. Water is essential for all known forms of life, and it is thought that any planet that has liquid water on its surface is likely to be habitable.So, what are the chances that there is life on other planets? It's impossible to say for sure, but there are some reasons to be optimistic. First, there are billions of stars in our galaxy, and many of them are likely to have planets orbiting them. Second, we know that there are many different types of planets, and some of them are likely to be habitable. Third, we have discovered that life on Earth is incredibly resilient. It can survive in a wide range of environments, from the depths of the ocean to the tops of mountains.Of course, there are also some reasons to be pessimistic. First, we have yet to find any definitive evidence of life beyond Earth. Second, the universe is a vast and dangerous place, and it is possible that life is very rare. Third, even if there is life on other planets, it is likely to be very different from life on Earth.Ultimately, the question of whether there is life beyond Earth is one that we may never know the answer to. But it is a question that is worth asking, and one that will continue to fascinate us for centuries to come.中文回答：地球之外还有生命吗？这个问题已经让人类着迷了几个世纪，而且我们可能永远无法确定答案。

2. 地球外生命的可能性2.1 地外生命存在的理论依据The possibility of extraterrestrial life existing is based on several theoretical foundations. One such foundation is the concept of panspermia, which suggests that life on Earth may have originated from microorganisms or organic molecules brought to our planet through meteorite impacts or interstellar dust. This theory proposes that if life could survive the harsh conditions of space travel, it is likely that similar forms of life could exist in other parts of the universe.Another theoretical basis for the existence of extraterrestrial life is the sheer vastness of the universe. The universe is estimated to contain billions of galaxies, each with billions of stars, and many planets capable of supporting life as we know it. With such an immense number of potential habitats, it seems plausible that at least some of them mayharbor alien organisms.Additionally, studies have shown that extremophiles –organisms capable of surviving in extreme environments on Earth –can thrive in conditions previously thought to be inhospitable for life. These extremophiles include bacteria living in deep-sea hydrothermal vents, in highly acidic environments, and even within rocks miles beneath the Earth's surface. Such findings suggest that if similar extreme conditions exist elsewhere in the universe, they may also support microbial life.2.2 太空中可能存在生命的环境条件In recent years, scientists have discovered a wide range of environments in space that could potentially support life. One example is Europa, one of Jupiter's moons, which has a subsurface ocean beneath its icy crust. This ocean may contain all the necessary ingredients for life: liquid water, organic compounds, and a source of energy from volcanic activity or tidal forces generated by Jupiter's gravitational pull.Another intriguing location is Saturn's moon Enceladus, which has geysers spewing water vapor and organic molecules from its subsurface ocean into space. These plumes indicate the presence of hydrothermal vents similar to those found on Earth, providing potential habitats formicrobial life.Furthermore, exoplanets, which are planets orbiting stars outside our solar system, have also been identified as potential candidates for hosting life. Some exoplanets fall within the habitable zone of their star –the region where temperatures allow liquid water to exist on their surface. These exoplanets may possess atmospheres and environmental conditions conducive to supporting life forms similar to those found on Earth.2.3 具有潜在地外生命体迹象的行星及卫星Several celestial bodies in our solar system exhibit signs that raise the possibility of extraterrestrial life. One significant example is Mars, often referred to as the "Red Planet." Mars possesses a thin atmosphere and evidence suggests that liquid water once flowed on its surface. Recent discoveries of methane plumes and seasonal changes in atmospheric composition have sparked interest in the possibility of microbial life existing or having existed on Mars.Titan, Saturn's largest moon, is another intriguing target for astrobiology research. It has a dense atmosphere composed primarily of nitrogen, with traces of methane and other organic compounds. Lakes of liquidmethane and ethane have been observed on its surface, potentially offering an entirely different type of environment capable of supporting unique forms of life.These discoveries and observations highlight the potential existence of extraterrestrial life beyond Earth. Continued exploration and scientific investigation both within our solar system and beyond will be crucial in shedding further light on this exciting frontier of discovery.3. 最近研究发现与证据3.1 外星微生物化石发现研究成果最近的研究表明，在地球以外的行星和卫星上发现了一些可能是外星微生物化石的证据。

有趣的讨论议题英文作文

有趣的讨论议题英文作文English:"Is There Intelligent Life Beyond Earth?"This question has intrigued humanity for centuries, sparking countless debates, speculations, and scientific endeavors. As I delve into this intriguing topic, I find myself torn between skepticism and wonder. On one hand, the vastness of the universe suggests the possibility of extraterrestrial intelligence. On the other hand, the lackof concrete evidence leaves room for doubt.Considering the sheer number of stars and planets inthe observable universe, it seems statistically improbable that Earth is the only harbor of intelligent life. The famous Drake Equation, formulated by astronomer Frank Drake, attempts to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy alone. This equation takes into account factors such as therate of star formation, the fraction of stars with planets, and the likelihood of life evolving on those planets. While the Drake Equation is highly speculative and subject towide interpretation, it underscores the plausibility of intelligent life existing elsewhere in the cosmos.Moreover, advancements in astrobiology have revealedthat life can thrive in extreme environments on Earth, from deep-sea hydrothermal vents to acidic hot springs. This expands the range of potential habitats for life beyond our planet, including moons of gas giants like Jupiter and Saturn, where subsurface oceans might harbor microbial life. The discovery of extremophiles on Earth has fueled optimism that similar organisms could survive in seemingly inhospitable environments elsewhere in the universe.Furthermore, the search for extraterrestrialintelligence (SETI) continues unabated, utilizing radio telescopes to scan the skies for artificial signals indicative of intelligent civilizations. While SETI has yet to yield a definitive detection, the sheer scale of the endeavor reflects humanity's enduring fascination with thepossibility of cosmic companions.However, despite these compelling arguments, the absence of concrete evidence remains a significant obstacle. The Fermi Paradox, named after physicist Enrico Fermi, succinctly captures this conundrum: if intelligent life is common in the universe, why haven't we detected any signals or observed any visitations? Various hypotheses have been proposed to address this paradox, ranging from the notion that intelligent civilizations self-destruct before theycan make contact to the idea that interstellar travel is prohibitively difficult.Ultimately, the quest to unravel the mystery of extraterrestrial intelligence transcends scientific inquiry; it speaks to our deepest existential questions about humanity's place in the cosmos. Whether we discover intelligent life beyond Earth or not, the pursuit broadens our perspective and fosters humility in the face of the unknown.中文："地球之外是否存在智慧生命？"这个问题几个世纪以来一直让人类着迷，引发了无数的辩论、猜测和科学探索。

地球外有生命存在吗：一起来找证据!-中英互译

It’s my job to find aliens, so as you might guess, I spent a lot of time thinking about them, imagining little green women meeting up with their friends, commuting to work. And that gets me thinking about alien astronomers trying to find us in their night sky.我的工作是寻找外星人。

如你们所想，我花了很多时间琢磨他们，想象小小的绿皮肤女性和朋友们聚会，通勤上班。

这也让我想到，外星的天文学家们是不是也尝试在他们的夜空中寻找我们。

If these alien astronomers had looked in our direction in the last century, they would have been really excited to detect unequivocal signs of technology. But what if they looked 10,000 years ago, before we showed signs of civilization? Would they shrug in disappointment and go look elsewhere for life?如果外星的这些天文学家曾在上世纪看向地球，他们可能会为探测到明确的科技迹象而兴奋不已。

但如果他们是在一万年前，在我们还没有任何文明迹象的时候看向地球的呢？他们会失望地耸耸肩，然后去别的地方寻找生命吗？No, and neither should we. Instead, we can look for other signs of life. For example, if those alien astronomers had looked our way 10,000 years ago, they might notice that even without signs of civilization, we still looked slightly unusual. For one, we have a thick and temperate atmosphere.不会的，我们也不会。

2019年高考英语阅读理解一轮练(8)含解析

2019年高考英语阅读理解一轮练（8）李仕才AA recent survey in the United States showed that the average family spent more money on its pets than on its children. Although rather shocking, it should not surprise anyone who has seen the doggy parlours(客厅) where loved pets rest. Are Americans unique in treating their little friends in this way? No, the English, too, pay more attention to their pets.This can clearly be seen when we look at pet foods，which often contain more vitamins than human food. They certainly cost much. Last year the British public spent two hundred million pounds on pet food alone, to say nothing of veterinary bills or animal furniture. It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty, so it’s not unusual for me to get hot under collar when I read an old man left all his money to his dog instead of his children.There are a variety of reasons why I find pets-raising alarming. They cause physical problems. An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets. Many people find this funny, but in a number of large cities it is a major problem. Animals can cause disease, too. It is the threat of babies — a disease with no known cure.Another problem is the carelessness of pet owners. Most little children want a dog or a cat，and they continually push their mothers and fathers until they get one. It is only when the ＂sweet little thing＂ has been brought home that the parents realize how much time and money must be spent on ＂Rover＂ or ＂Bonzo＂. Then they just abandon it. As a result, they are allowed to run free. English farmers lose hundreds of sheep a year, killed by someone’s pet and you must have read of children being hurt by some pets of their own.Lastly, I would only suggest that we have got our priorities wrong and that something should be done about it. In my view, it’s time we stopped being sentimental about pets. I can see no reason why we should get upset when animals are cut up formedical experiments. This will lead us to discovering cures for serious human diseases, then I say,＂keep cutting!＂1.

You may choose a paragraph more than once.NASA Next Giant LeapA)It was 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era. Starting from the moon, we will move deeper into the solar system. The Apollo missions cleared a path for human exploration to the moon. Today we are extending that path to near-Earth asteroids(小行星), Mars and beyond.B)We are building on the Apollo program accomplishments to test and fly novel(新的), cutting-edge(尖端) technologies today for tomorrow missions. As we develop and test the newtools of 21st century spaceflight on the ourneyo Mars, we once again will change the course of history.C)The path to Mars begins with research on Earth and extends beyond its bounds, aboard the orbiting laboratory of the International Space Station, with our international partners. Some 250 miles above our heads, astronauts are conducting hundreds of experiments not possible on Earth, teaching us how humans can live, work and thrive(长得健壮) for longer periods in space.D)To help this nation send humans to deep space and return them to Earth safely, engineers across the country are developing a new space transportation tool that can travel far beyond our home planet. The Orion spacecraft and Space Launch System (SLS) heavy-lift rocket will be the most advanced space vehicles ever built. Together, they will take us farther into the solar system than humans have ever traveled. They are our spaceship to Mars and beyond.E)As we turn our eyes toward Mars, we are designing missions to take us to a roving ground?around the moon called cis-lunar(月球周围) space, where some of the very building blocks of the solar system can be explored.F)Near-Earth asteroids provide a unique opportunity we need for future human missions to Mars. Around 2019, we launch a robotic mission to reach a near-Earth asteroid. The spacecraft either will capture an entire asteroid or take a part off a much larger asteroid, then redirect the asteroid mass to a stable orbit(轨道) around the moon. Such missions will provide important information about the space to safely send humans to Mars.G)The new technologies we test by sending astronauts to study the asteroids in the cis-lunar space will make important advances to safely send humans to Mars. This includes tools like Solar Electric Propulsion, a highly efficient way to help us transport large objects and heavy cargo to support future Mars missions. NASA will continue to make significant investments in new technologies vital to achieving exploration goals. This includes advancements in entry, descent and landing technologies such as ow Density Supersonic Decelerators.H)Sending humans to deep space around the moon also will help advance techniques for space operations on and around Mars and its moons. The space around our moon is different than low-Earth orbit but very similar to what a spacecraft will experience on the trip to and from Mars. For instance, solar and cosmic radiation is intense. We also can use cis-lunar space to begin practicing activities in deep space, like spacewalks, and learn to cope with delays in communication with Earth because of the distance.I)Mars calls for us to explore. Missions to Mars could answer some of the fundamental questions of humanity: Does life exist beyond Earth? Could humans live on Mars in the future? J)The journey to answer these questions has risks, but the rewards for humanity are worth it. In our lifetime, NASA and the world will take the next giant leap to explore the red planet.______11.Preparation for the journey to Mars can start from a place near Earth.______12.People from different countries contribute to the exploration of Mars in one way or another.______13.Great benefits will be gained from missions to Mars.______14. A number of new technologies will be needed to send human beings to Mars.______15Despite the risks, it is worthwhile to take this great leap to explore Mars.______16.We are now standing on a new horizon, ready to take the next giant leap.______17.If we want to travel to Mars, a more powerful form of transportation is needed.______18.The cis-lunar space will serve as a genuine training ground.______19.New missions near Earth will provide new information before we really send a human being onto Mars.______20.The Apollo program has provided a strong base for our future explorations.Section CDirections: There are two passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice.Passage OneBelieve it or not, there is a whole generation of young people who would love to own a personal airplane but who have little or no interest in learning to fly. To satisfy demand from this new kind of traveler, futurists dream of building airplanes that will fly themselves with minimal input from their occupants(用户). Rather than planning a flight, checking weather and attending to all the other duties of pilot-in-command, the operators of these future aircrafts will simply hop in the front seat, press a few buttons (or merely speak to the flight computer) to input the desired destination and then kick back while the virtual(虚拟的) pilot does all the flying.It hard to imagine what level of understanding of aerodynamics(空气动力学) or aviation rules and regulations the operator of such a futuristic airplane would be required to possess, but for this concept to work the answer quite probably would have to be very little to none. After all, a 損ilot?who is so far removed from the decision-making processes and the actual hands-on flying of the airplane shouldn抰be depended on to take over in an emergency. Instead, these future general aviation airplanes will be little more than passenger-carrying UAVs (unmanned aerial vehicle[无人驾驶航空器]).In such cases, trained pilots on the ground could be given access to the airplane controls through a secure datalink(数据链) connection, enabling the remote operator to take over ?for a fee, of course. It similar to a concept now being debated in the airline world, where future Boeing and Airbus jetliners would have only one pilot physically on board the airplane with ground-based copilots available to step in as needed.We may not like the idea, but as we are seen in the UAV world, such operations are already possible. As the technology evolves and matures to enable airplanes to fly and land automatically without any help from humans, there no reason why airplane manufacturers (制造商) 20 years from now might not start offering a cockpit as optional equipment.21.What do futurists dream of?A) Owning a personal airplane. B) Attending to the duties of a pilot.C) Making planes with automatic piloting. D) Flying an airplane by themselves.22.What is the main characteristic of the new kind of traveler?A) They have considerable interest in learning to fly.B) They like owning and flying a personal airplane.C) They like to speak to the flight computer.D) They want to fly an airplane with minimal efforts.23.Which of the following is true of the virtual pilot on such futuristic airplanes?A) It is not as good as a human pilot. B) It knows everything about aerodynamics.C) It can easily replace a human pilot.D) It can take over in times of emergency.24.It is still necessary for human pilots on the ground to control such a plane because ______.A) such a plane is no more than an unmanned aerial vehicleB) the virtual pilot cannot handle an emergencyC) human pilots can make more money for thisD) there is a datalink connection to the controls25.Which of the following can serve as a proper title for the passage?A) The New Kind of Traveler C) The Virtual PilotB) The Fully Automated Airplane D) The Removed Human PilotPassage TwoNASA is now trying to make a spaceship that is much better than other ships.If we look at the things we need for our super spaceship, there seems to be one that is the most important. The spacecraft has to be as light as it can be. Weight costs money!A new discovery might allow spacecraft to be lighter. Imagine something that is stronger than steel but also weighs less. A new material called arbon nanotube?碳纳米管) might be the answer to the weight problem of building a super spaceship. This material is 600 times stronger than steel.One of the big problems with space travel is the radiation that in space. On Earth, our atmosphere protects us from radiation. In space, however, astronauts need protection against harmful rays.You might think that the metal on a spaceship is the answer. But, metals are the worst for shielding against very dangerous space rays. These rays are made of little pieces called ions(离子). When the ions hit metals at very high speeds, they can break an atom and cause another type of ray to form. These new rays can be worse than the radiation the metal skins were supposed to stop.You see why it is so important to block out these rays.But, we could use carbon nanotubes to make the skins of spacecraft. Nanotubes look a little like chicken wire that is too small to see.Things that are light in weight seem to work the best against these ions. When the rays hit lighter things, very little new radiation is made. The rays are stopped outside the spacecraft and new rays aren’t made.In addition, our super spaceship needs to be able to repair itself. This might really be possible. Humans can feel the smallest pinpricks(针刺) because of tiny sensors that send signals to our brains. Tiny sensors like ours could be built in the new ships. Each sensor could send messages to the computer rain?of the spacecraft. If something needed to be fixed, the computer could tell the ship to do it.Just as amazing as a car would be to someone 200 years ago, our nanotube spaceship might seem to us. We might actually make the spacecraft of tomorrow, using the technology of today.26.What is NASA trying to do?A) To make carbon nanotubes. B) To protect astronauts from ions.C) To make a new discovery.D) To build a super spaceship.27.Carbon nanotubes could be used to make the skins of spacecraft because ______.A) they are much lighter than metalB) they are 600 times stronger than steelC) they can shield the spacecraft from radiationD) they can break ions in space rays28.What will happen when ions hit the metal on a spaceship?A) Some worse radiation will be produced.B) All radiation will be blocked out.C) The metal on the spaceship will break up.D) The ions will move at high speeds.29.Tiny sensors will be built into the new spaceship so that ______.A) the computer brain can feel the smallest pinpricksB) the spaceship can have human sensationsC) the sensors can send signals to the spaceshipD) the spaceship will be capable of repairing itself30.What is the passage mainly about?A) How to build a future spaceship.B) How to make use of carbon nanotubes.C) How to protect astronauts in space.D) How to block out radiation.Part III TranslationDirections: Translate the passage from Chinese into English.周六，在戈壁滩发射基地——甘肃省酒泉卫星发射中心，神舟九号飞船载着中国第一位女宇航员升空。
