Space explorationRobots will not only help us on this world. But will also help us explore other worlds. In fact, space exploration is one of the most promising usages for robots. Since these machines are not so susceptible to the elements that could hurt or kill people. Robots can withstand radiation, heat, cold and can function without an atmosphere. Also robots have a much longer life span. So voyages to other solar systems as well as other planets would be possible. Robots could communicate with us and if something went wrong and destroyed, the space vehicle and a machine would be lost, not a human being.机器人用于空间探索机器人不仅会在这个星球上帮助我们，而且还将帮助我们探索别的星球。
实际上，空间探索就是机器人最有前途的用途之一，知识因为机器人对于机器人会使人伤亡的自然环境和条件不很敏感。
机器人能经受得住辐射，耐热又耐寒，而且能在没有大气的环境中的工作。
此外，机器人的使用寿命长得多。
因此不但可飞往别的行星，而且可飞往别的星系。
机器人可跟我们进行通信联络，要是有什么东西除了毛病，而损坏了宇宙飞行器的话，失去的是机器人而不是人。

关于科技的英语作文加中文Here is an English essay about technology, with a word count greater than 1000 words. The essay is written without the title and without any extra punctuation marks.As the world continues to evolve and progress, the impact of technology on our lives has become increasingly profound. From the way we communicate and access information to the way we work and entertain ourselves, technology has transformed nearly every aspect of our daily existence. In this essay, we will explore the multifaceted role of technology in our lives and its far-reaching implications.One of the most significant ways in which technology has shaped our world is through communication. The advent of the internet and mobile devices has revolutionized the way we stay connected with friends, family, and the global community. Social media platforms, instant messaging apps, and video conferencing tools have made it possible to bridge geographical barriers and foster real-time interactions, even across continents. This enhanced connectivity has not only strengthened personal relationships but also facilitated the exchange of ideas, the dissemination of information, and thepromotion of cultural understanding on a global scale.Furthermore, technology has revolutionized the way we access and process information. With the vast resources available on the internet, we can now readily obtain knowledge on virtually any topic, from the latest scientific breakthroughs to the cultural traditions of distant lands. The proliferation of search engines, online databases, and digital libraries has empowered individuals to become self-directed learners, allowing them to expand their horizons and deepen their understanding of the world around them. This access to information has also fueled innovation and creativity, as people can easily research, collaborate, and build upon the ideas of others.In the realm of work and productivity, technology has transformed the way we approach our professional lives. The rise of automation, artificial intelligence, and cloud computing has streamlined numerous business processes, increasing efficiency and reducing the time and effort required to complete various tasks. This has allowed companies to focus on more strategic and value-added activities, ultimately enhancing their competitiveness and profitability. Furthermore, the advent of remote work and telecommuting has provided greater flexibility and work-life balance for employees, as they can now perform their duties from the comfort of their own homes or from any location with a stable internet connection.The impact of technology extends beyond the realms of communication, information, and work, as it has also transformed the way we entertain ourselves and engage in leisure activities. The proliferation of streaming platforms, online gaming, and augmented reality applications has revolutionized the entertainment industry, offering a vast array of content and experiences to cater to diverse preferences and interests. These technological advancements have not only expanded the options available to consumers but have also provided new avenues for creative expression and artistic exploration.However, it is important to acknowledge that the advancement of technology is not without its challenges and drawbacks. The reliance on digital devices and the constant connectivity can lead to issues such as screen addiction, social isolation, and the erosion of face-to-face interactions. Furthermore, the rapid pace of technological change can create a digital divide, where certain individuals or communities may lack access to these advancements, resulting in a widening of the socioeconomic gap.Moreover, the rise of data-driven technologies has raised concerns about privacy, data security, and the ethical use of personal information. As we increasingly entrust our personal data to digital platforms and services, the need for robust cybersecurity measures and transparent data management practices has become increasingly crucial. Navigating these ethical and privacy-relatedchallenges will be a crucial aspect of ensuring that technological progress benefits society as a whole, rather than privileging a select few.Despite these challenges, the overall impact of technology on our lives has been undeniably transformative and largely positive. By enhancing communication, expanding access to information, improving productivity, and enriching our leisure experiences, technology has undoubtedly played a pivotal role in shaping the modern world. As we continue to embrace and harness the power of technological advancements, it is crucial that we do so with a keen awareness of the potential pitfalls and a commitment to leveraging these tools in a responsible and equitable manner.科技在我们生活中扮演着日益重要的角色。

科技类词汇对应阅读passage1A snake﹣robot designer，a technologist，an extradimensional physicist and a journalist walk into a room.The journalist turns to the crowd and asks：Should we build houses on the ocean？Like a think﹣tank panel，members of the team dream up far﹣out answers to the crucial problem，such as self﹣driving housing units that could park on top of one another in the coastal city center.The setting is X，the enterprise which considers more than100ideas each year，in areas ranging from clean energy to artificial intelligence.Although only a tiny percentage become"projects"with far﹣reaching creativity，these projects exist，ultimately，to change the world，like Waymo，the biggest self﹣driving﹣car company.In the past60years，something strange has happened.As the academic study of creativity has thrived （蓬勃发展），the label innovation may have covered every tiny change of a soda can or a toothpaste flavor，but the rate of productivity growth has been mostly declining since the1970s.John Fernald，an economist，points out that the notable exception to the post﹣1970decline in productivity occurred when businesses throughout the economy finally figured out the breakthrough technology﹣information technology.John Fernald says，"It's possible that productivity took off，because we picked all the low﹣hanging fruit from the IT wave."Actually，the world economy continues to harvest the benefits of IT.But where will the next technology shock come from？Breakthrough technology results from two distinct activities﹣invention and innovation.Invention is typically the work of scientists and researchers in labs，while innovation is an invention put to commercial use.Seldom do the two activities occur successfully under the same roof.They tend to thrive in opposite conditions；while competition and consumer choice encourage innovation，invention has historically progressed in labs that are protected from the pressure to generate profit.Allowing well﹣funded and diverse teams to try to solve big problems is what gave us the computer and the Internet.Today，we fail to give attention to planting the seeds of this kind of ambitious research，while complaining about the harvest."Companies are really good at combining existing breakthroughs in ways that consumers like.But the breakthroughs come from patient and curious scientists，not the rush to market，"says Jon Gertner，the author of The Idea Factory."Technology is a tall tree，"John Fernald said."But planting the seeds of invention and harvesting the fruit of innovation are entirely distinct skills，often mastered by different organizations and separated by manyyears."As for me，both of them are essential for technology，although they are relatively independent.I don't think X is a planter or a harvester，actually.It is like building taller ladders.Nobody knows for sure what，if anything，the employees at such enterprises are going to find up on those ladders.But they're reaching.At least someone is.（1）What is the main purpose of the first two paragraphs？A．To present the process of group discussion.B．To illustrate X's worry about big problems.C．To reveal the importance of the crazy ideas.D．To stress the varied backgrounds of the team.（2）What can we learn from the passage？A．Breakthroughs must stand the test of the market.B．Innovation on necessities can promote productivity.C．Invention develops slowly under the pressure of profit.D．The harvest of innovation lies in some ambitious research.（3）Regarding John Fernald's view on technology，the author is.A．supportiveB．cautiousC．uncertainD．critical（4）What can be inferred about X from the passage？A．It will focus on innovation.B．It will have its outcome soon.C．It may give in to its fruitless reality.D．It may bring an encouraging outlook.【分析】这是一篇说明文。

Technology has become an integral part of our lives, and it has significantly impacted the way we live, work and communicate. In my opinion, technology has both positive and negative effects on our lives.On the one hand, technology has made our lives more convenient and efficient. For example, we can now communicate with people from all over the world instantly through social media platforms like Facebook and Twitter. We can also shop online and have our purchases delivered to our doorstep, saving us time and effort. In addition, technology has revolutionized the way we work, allowing us to work remotely and collaborate with colleagues from different parts of the world.On the other hand, technology has also had some negative effects on our lives. For instance, the overuse oftechnology can lead to addiction and social isolation. People may spend too much time on their phones or computers, neglecting their relationships with family and friends. Moreover, technology has also led to job displacement, as many jobs are now automated, leaving many people unemployed.中文：科技已成为我们生活中不可或缺的一部分，它对我们的生活、工作和交流方式都有着重要的影响。

I thought only I had that problem.哈我认为只有我有这个顾虑Luckily enough, if we want to use one of these things for stellar travel,幸运的是如果我们想用其中一个彗星进行星际旅行we have quite a few to choose from!我们的选择有很多！According to NASA,根据美国航天局there are around 3,600 comets that we currently know of.我们目前已知的彗星约有3600颗Beyond that, it’s believed that there are billions of other comets out there此外据说在遥远的柯伊伯带还有数十亿颗彗星orbiting our Sun in the Kuiper Belt and even more distant Oort Cloud. 甚至是更远的奥尔特云围绕着太阳运行的What makes comets great for getting around in space彗星能够穿梭星际is that they can go SUPER fast.是因为其速度极快Yeah, this baby can fly!是的这小东西会飞！How fast they’re travelling depends on a bunch of different factors,它们的速度取决于多种不同因素but they can travel anywhere from a few thousand kilometers per hour,但在一定条件下它们的速度可以从时速几千公里to over 160,000 kilometers per hour under certain conditions.达到每小时超16万公里在任何地方飞行In fact, in 2016, scientists at NASA recorded2016年美国航天局的科学家们记录了a comet traveling at nearly 600 kilometers per second as it dove toward the Sun.一颗秒速六百公里驶向太阳的彗星That’s over 2 /million/ kilometers per hour!那超过了两百万公里每小时！To put that in perspective,就此展望if we could travel at 2 million kilometers per hour,如果我们能以每小时两百万公里的速度飞行then wecould get to Mars from Earth in around 28 hours,我们可以在一天多的时间里just little more than a single day,约28小时就可以完成火星之旅assuming the two planets were close together in their orbits. 假设轨道上有两颗行星距离很近Lining up the planets is the least of our worries though.我们可以在可控范围内排列行星While comets can go super fast,彗星的速度超快getting to them would be a big problem.登上彗星仍会是一大问题That’s because, not even considering how hard it would be to actually commandeer one,因为我们甚至没有考虑控制一个彗星有多难comets just don’t typically get that close to Earth.彗星一般离地球很远Hale-Bopp, a comet that made the news about two decades ago, 大概二十年前新闻上报道了海尔-波普彗星came closer to Earth than most comets do,它比大多彗星更靠近地球and it was still about 200 million kilometers away.但还是有约两百万公里的距离We might as well just go straight to Mars at that point!照那样我们还不如直接去火星吧！Even if a comet did come by Earth,即使彗星确实经过地球we assume that its trajectory is towards Mars,我们也断定它的轨道是朝着火星的and we ignore that it would likely be in its more gassy, less-solid state,并且我们忽略了它可能更多的是气体而非固态物质you’d still have to keep yourself alive on the comet.你还要在彗星上生存下去I guess if it’s only a day or so then food and water would be less of an issue我猜如果只是一天左右那食物和水就不是问题了since the aliens would definitely feed you once we got there,因为一旦我们到了那里外星人肯定会伺候我们的but you’d still have to worry about oxygen and protecting your self from space.但你仍要担心氧气并且保护自己远离太空You would need about 0.84 kilograms of oxygen a day,你每天约需0.84公斤的氧气so you better grab a spacesuit and take a big breath before jumping on the comet.所以跳上彗星前你最好穿上宇航服深吸一口气So yeah, using comets as a means of space travel is probably not that viable in the end.所以利用彗星进行太空旅行或许并不可行Sometimes I like doing these thought experiments, you know,有时我喜欢做这些思维实验and then realizing that they can’t work.然后意识到不可能实现But it’s still interesting!仍然它仍很有趣！That’s how we learn people!这也是咱认识人类的方法！So do you have any questions about space that you want me to answer.你有关于太空的疑问想要我解答？Any planets that we should cover next?接下来我们要讲哪些行星？Let me know right now in the comment section below!请立刻在下方评论区告诉我吧！Curious to know what would happen if you were trapped on the international space station?我很好奇如果你被困在国际空间站会发生什么？We teamed up with our friend William Osman to answer that question.我们会与我们的朋友William Osman一起为你解答ISS actually gets its power from solar arrays made up of thousands of solar cells.国际空间站的能量来自上万个太阳能电池组成的阵列These arrays can efficiently covert solar energy into electrical power. 这些阵列可以有效地将太阳能转换成电能Typically producing more power than the station needs at one time. 通常在同一时间产生超出所需的电力（二）饮水鸟蕴含的工程学原理The Engineering of the Drinking BirdThis toy has fascinated me since childhood.我从小就对这个玩具着迷To me its motion is almost hypnotic.对我来说它的运动就像是催眠Here’s how it operates.它是这样运转的Wet the bird beak thoroughly with room temperature water.将鸟喙完全浸透在室温的水中The opaque container makes it looked chilled,不透明容器使它看起来冷淬了but it isn’t…其实并没有Then stand it upright…然后让它直立It will take a few seconds for it to start drinking…它要等几秒钟后才开始喝水Notice that all of the action right now takes place in the stem here 注意现在所有的运动都发生在躯干这里As l speed up the action当我快进这个过程you see liquid rising and the bird rocking back and forth.可以看见液面上升饮水鸟开始前后摇摆If I return to normal speed,如果调回常速播放you can see the bird slowly …可以看到饮水鸟慢慢地very, very slowly ….非常非常慢地Rock forward…向前摆动Until it takes a drink,直到它喝到了水which it will do again and again.然后一遍又一遍地重复此过程In this video I’ll detail the bird’s clever engineering design,在本视频中我将详述这只鸟精妙的工程设计explain how it uses thermodynamics,阐明它是如何运用热力学知识and link its action to some of the greatest将其运动与一些工程师创造的and most impactful devices created by engineers.伟大且影响深远的装置联系起来的This toy has long history,这个玩历史悠久but its current incarnation is due to Miles V. Sullivan—它的当前形态是由贝尔实验室一名科学家a scientist at Bell Labs.Miles V. Sullivan创造的He specialized in methods of manufacturing semiconductors,他专精于研究制造半导体的方法but as a sideline invented toys.发明玩具是他的副业Its reported that this bird delighted U.S. President Herbert Hoover,据说这只饮水鸟深得美国总统赫伯特·胡佛喜爱an engineer who failed to figure out how it worked,作为一名工程师他没搞懂它的工作原理and it also defeated the great scientist Albert Einstein,而且它还难倒了伟大的科学家艾尔伯特·爱因斯坦who spent three and half months studying it.爱因斯坦花了三个半月来研究它It’s reported that he refused to take the bird apart.据报道他拒绝把这只鸟拆开With the benefit of hindsight,有了后见之明let’s start by exploring how it works让我们从探索它的工作原理and examining the key engineering design aspects.以及检查关键的工程设计方面开始First, let’s ask is the water ornamental or essential?首先要问的是水是装饰品还是必需品？At first the bird acts just as if the water were still there.最初饮水鸟的行为好像水还在那里一样Now let’s speed up the bird’s motion我们快进饮水鸟的动作you see at 15 minutes it is still drinking.可以看见过了15分钟它仍在喝水At 30 still drinking.30分钟还在喝水45 minutes still drinking.45分钟依然还在喝水60 minutes still drinking.60分钟还在喝水75 minutes still drinking.75分钟仍然还在喝水And five or ten minutes later,又过了5到10分钟后at eighty or eight-five minutes it takes its last drink.约在80到85分钟它喝了最后一次水The liquid still rises a bit,虽然液面上升了一点but it never rises enough to make the bird tip over,但它从没上升到足够使鸟翻倒的高度which shows that the motion is not perpetual说明这个运动不是永恒的—as long as there is water, the bird keeps drinking.只要有水鸟就一直喝水Let’s look inside the bird来看看饮水鸟的内部to get an idea of how it works.了解它的工作原理Underneath the bird’s hat, beak and fabric covering lies a glass bulb 在鸟帽鸟嘴和织物覆盖物下面有一个玻璃泡smaller than the bulb at the base, and also rounder.它比底部的玻璃泡小也更圆Now, watch as I put a few drops of isopropyl alcohol on the bulb to cool it.现在我滴几滴异丙醇在玻璃泡上使它降温The liquid rapidly rises to the head,里面的液体快速上升到头部this changes the bird’s center of gravity这改变了饮水鸟的重心so that it will tilt forward.使它向前倾斜The head now fills with liquid and then …现在头部充满了液体接下来……there…你看…it …drinks.它喝水了It becomes upright and the liquid drains from the head.它直立后液体从头部排出Liquid rises again to the head and…液体再一次上升到头部……the bird drinks again.饮水鸟再一次喝水This cycle repeats until all of the isopropyl alcohol on the bird ’s head evaporates.这个过程循环往复直到鸟头上的异丙醇都蒸发掉Why does the liquid rise?为什么液面会上升呢？The place to begin is with the bird’s manufacture.我们从饮水鸟的制造说起The bird is filled through this “tap ”—a small pipe built into the head —通过装在头部里的小管子即龙头with methylene chloride dyed red, which is then frozen,向鸟内装入冷冻的染成红色的二氯甲烷a vacuum applied to evacuate the air,抽走空气形成真空the tap sealed ( and of course, later hidden by the bird’s hat )…把龙头密封(当然后来被鸟帽盖住了)And then the methylene chloride melts:之后二氯甲烷融化It turns to liquid and then some of it evaporates（turns into vapor）.转变为液态其中部分二氯甲烷蒸发(变成蒸汽)The key to the bird’s operation is饮水鸟运转的关键就在于that the vapor in the head and in the base are separated by the liquid in the base.头部和底部的气体被底部的液体所隔离It’s hard to see,这很难看清楚but the tube extends into the base, nearly reaching the bottom.不过管子延伸到底部几乎接触到底面This separates the vapor in base and the vapor in the tube使得底部和管中的气体隔离……and …of course, the head.当然还有头部的气体So, at rest the pressure in these two spaces are equal,在静止状态这两个空间的压强相等but when the bird’s beak is wet,但当鸟喙湿润时the temperature falls鸟喙温度下降and as I’ll explain in a moment the pressure in the head drops头部的压强下降这个我稍后会解释below that in the base and the liquid rises.降到低于底部的压强然后液面上升Of course this liquid in the head causes the bird to…tilt forward, to drink …自然头部的液体导致饮水鸟向前倾斜喝水and when it drinks,当它喝水时the vapor in the head and the base are connected,头部和底部的蒸汽连通the pressures is nearly equalize两端压强几乎相等—a slug of vapor rises to the top and some liquid drains from the head一股蒸汽上升到头部迫使部分液体流出and then the cycle repeats.然后循环重复To see the pressure equalize为了看到压强平衡过程l will slow down the bird as I tilt it forward.我会慢一点倾斜饮水鸟Right now the head is half full.现在头部已经半满了When I tilt it you see a slug of vapor go from bottom to top.当它倾斜时可以看见一股蒸汽从底部升到顶部I’ve tilted it far enough forward我把它倾斜得够多that the liquid in the head is below the top of the tube以至于头部的液面低于管子的顶端and the liquid in the base is below the section of the tube that almost reaches the bottom of the bird.同时底部液面也低于几乎触底的管子底端This allows the pressure to equalize,这样头部和底部的压强相等and as the bird becomes upright而当饮水鸟站起来时the liquid returns to the base before the cycle starts again.液体会在下一次循环开始之前返回到底部In operation it doesn’t tilt quite this far forward实际运转时它不会向前倾斜这么多and so the pressures don’t fully equalize.因此压强不会完全平衡Why, though, does the pressure in the head drop as the temperature falls?那么头部压强为何会随着温度下降而下降呢？You can see the answer if I shoot cool, compressed gas across the bird’s head.你看我向头部射低温压缩气体就知道答案了As the cool gas strikes,遇到低温气体时you see liquid condensing inside the head;头部内壁出现了冷凝的液体and, as you see on the left,正如你在左图看到的this causes the liquid in the base to rise.这导致底部的液面上升The cool gas withdraws energy as heat from the head,低温气体带走头部的热量causing some of the methylene chloride vapor inside to condense –to turn into a liquid.导致头部部分二氯甲烷气体冷凝成液体This decreases dramatically the amount of vapor in the head.这大大减少了头部的气体体积Liquid is 1,000 times more dense than vapor.液体的密度是气体的1000倍This in turn lowers the pressure in the head and causes the liquid to rise.结果降低了头部的压强使液面上升I used compressed gas to cool the head我用压缩气体给头部降温because I can control the amount of cooling;因为我可以控制降温的程度the bird, though, cools its head by “drinking.”然而饮水鸟通过喝水来降温The head is wrapped in fabric that absorbs water.其头部包裹在吸水的织物中As I put drops on its beak当我把水滴在鸟喙上you can see the water beads up at first…一开始你可以看到水珠……and then saturates the fabric and spreads rapidly across the bird’s face.然后水珠浸透织物并迅速扩散到鸟的整个面部On the right side you can see it creeping to back of the head.从右边看可以看到水渍浸到了后脑勺If I now turn the bird around,如果我现在把鸟转过来you can see that the water has spread to the back.可以看到水已经蔓延到后面As I continue adding drops on the beak如果我继续往鸟喙上滴水the saturated area on the back increases.头背处渗水区域扩大When this water evaporates into the air, it removes energy from the bulb as heat当水蒸发到空气中带走了头部的热量you feel this effect every time you step out of the shower,每次你洗完澡都会有这种感受the evaporating water withdraws energy as heat and chills you.蒸发的水带走热量让你感到冷飕飕的This evaporation, this withdrawal of heat, lowers the temperature 蒸发吸热降低了头部的温度and begins the condensation of the vapor, which starts the cycle 蒸汽冷凝启动循环as I showed you with the cool, compressed gas.就像我之前用低温压缩气体做的演示一样As long as the head is wet and heat is withdrawn from it,只要头部保持潮湿而且有热量带走the bird will always “drink, ”饮水鸟将一直“喝水”but if you were to operate the bird in humid air,但如果你把饮水鸟放在潮湿的环境it would slow down, because little water would evaporate,它就会减速喝水因为很少有水分蒸发and if the air were at 100 % humidity the bird would stop如果空气湿度是100% 饮水鸟将停止喝水because no water would evaporate at all.因为根本没有水蒸发Now, to make this dramatic condensation happen现在为了达到明显的冷凝效果when the temperature is lowered just slightly当温度只稍微降低时the evaporating water lowers the temperature by only about three-tenths of a degree水的蒸发只降低了0.3 度the bird’s designer choose a highly volatile liquid.饮水鸟的设计者选择了一种极易挥发的液体This means one whose boiling point is near ambient temperature这就需要这种液体的沸点接近室温because for small changes in temperature因为即使温度轻微变化there is a large change from vapor to liquid从气态至液态的变化也是巨大的and so the variation of pressure is large.从而引起压强的巨大变化Watch what happens as I “heat ”the base of the bird with my hand.观察我用手加热饮水鸟的底部时会怎么样You see the liquid level in the base dropping,可以看到底部的液面在下降that’s because energy from my hand is converting some of the liquid into vapor,这是由于手的热量使部分液体转化成气体which increases the pressure in this region…增大了这个区域的压强and that causes the liquid to rise to the head.从而使液体上升到头部Eventually I heat the vapor so much that it shoots up the stem.最终我把蒸汽加热到从管子中冒出来Now watch as I place my hand around the head.现在看我把手放在头部Heat from my hand converts liquid to vapor,手上的热量将液体转化为蒸汽which increases the pressure从而增大了压强and forces the liquid back to the base.并迫使液体回到底部To test this explanation of the bird’s operation,为了验证这个饮水鸟运转的解释let’s activate the bird in different ways.让我们用不同方式来触发饮水鸟As I noted it is the temperature difference between its top and bottom我说过是它顶部和底部的温差that drives liquid to rise to the head.驱使液体上升至头部So, let’s see what happens if I point a light at the base of the bird,那么我们看看对底部进行光照会怎么样which I’ve painted black我把饮水鸟的底部涂成了黑色so it will absorb the energy from the light better.这样它能更好地吸收光能As I heat the base of the bird,当我给饮水鸟底部加热时the liquid rises, as before but …液体像之前一样上升但是……五倍速播放the bird tips backwards.饮水鸟向后倾斜The wet nose tilted the center of gravity……湿润的鼻子倾斜了饮水鸟的重心……and so I added some modelling clay to the nose于是我在鸟鼻子上加了些粘土to get the bird to tilt forward.好让鸟向前倾斜And now when I turn on the light the liquid rises,现在当我打开灯光液体上升the birds drinks as if there were liquid in front of it until…鸟儿就像面前有水一样喝水直到……I turn the light off我把灯关掉and the bird drinks for a little bit longer until eventually…这只鸟再坚持了一会儿直到最终……it comes to rest.它停了下来Next, let’s see what happens if we use this: Whiskey.接下来让我们看看用这个会怎么样：威士忌Again, thoroughly wet the bird’s beak with the liquid…再次用液体浸润鸟喙……stand it upright …让它直立……and then we see again the liquid rising in the bird …然后我们又看到饮水鸟体内的液面上升and then …it drinks.然后……它在喝水We can also now understand why the bird’s rate of drinking differs 我们现在也能理解在三种不同的刺激下among the three methods I used to “activate ”the bird:为什么饮水鸟的喝水频率不同了a heat lamp, whiskey and water.加热灯威士忌和水三种刺激Roughly, heat bird takes three drinks for every one of the water bird,大致上饮水鸟每喝一次水受热鸟喝三次the whiskey bird takes two for every drink of the water bird.而饮水鸟每喝一次饮酒鸟喝两次The reason the bird drinks whiskey faster than water is之所以饮酒鸟比饮水鸟快because the rate of evaporation of the alcohol is greater than that of water.是因为相对于水酒精更易挥发This means that heat is withdrawn faster from the head也就是说头部的热量散失更快and so more vapor condenses in a shorter amount of time,短时间内冷凝的蒸气更多which accelerates the pressure difference.从而加速扩大压差The heat lamp causes the greatest difference of all,加热灯导致的压差最大which highlights how an engineer thinks about this bird.这重点表明了工程师对饮水鸟的想法To an engineer this bird is a heat engine.对工程师来说饮水鸟是一个热机A heat engine turns heat differences into work —mechanical motion.热机将热能转化为功——机械运动To see that recall that when the bird is just about to drink回想一下当鸟正要喝水时that its head is at a lower temperature than its base,它的头部温度比底部的低which is at ambient temperature.底部温度就是环境温度Then when it “drinks ”, the pressure in the head and base start to equalize,当它“喝水”时头部和底部的压强开始平衡so liquid returns to the base,于是液体回到底部but the overall temperature of the bird但是现在饮水鸟的整体温度is now just a little below ambient temperature.只是稍低于环境温度When it return to upright, the base draws in energy as heat…当它恢复直立时底部吸热……the head then rejects some energy as heat头部放热and the bird drinks again.然后饮水鸟再次喝水These two flows define a heat engine:这种热传递定义了热机：a device, operating in a cycle一种循环运行的装置that absorbs heat from a high temperature reservoir,从高温热源处吸热converts part of it into work,将部分热能转化为功and rejects the remainder into a low temperature reservoir.向低温热源放热The fact that this is a heat engine饮水鸟就是热机这一事实means it’s related to the great machines that make our globalized world happen:表明它跟实现全球化的许多伟大机器有关among those the mighty steam turbine that generates electricity,其中有能发电的大型蒸汽轮机the giant diesel engine that propels container ships across the oceans,推动货轮穿越海洋的大型柴油机and the great gas turbine that flies us around the globe.还有让我们飞遍全球的燃气轮机（三）人们是否应该接受人造肉Lab-Grown Meat Is Coming to Your

现代科技阅读英文作文
现代科技阅读英文作文英文：Modern technology has greatly impacted the way we read. With the rise of e-books, audiobooks, and online articles, we have access to more reading materials than ever before. However, this convenience comes with its own set of challenges.One challenge is the potential for distraction. With the internet at our fingertips, it's easy to get sidetracked by social media, emails, or other online content. This can make it difficult to focus on reading for extended periods of time.Another challenge is the impact on our eyes. Reading on electronic devices for long periods of time can cause eye strain and other vision problems. This is why it's important to take breaks and give our eyes a rest.Despite these challenges, modern technology has also made reading more accessible and convenient. E-books and audiobooks can be downloaded instantly, and online articles can be accessed from anywhere with an internet connection. This means that people who may not have had access to physical books or magazines in the past can now read and learn more easily.Overall, modern technology has both positive and negative effects on the way we read. It's up to us to finda balance and use technology in a way that enhances our reading experience rather than detracts from it.中文：现代科技对我们的阅读方式产生了巨大的影响。

摘要
Abstract
The vocabulary of any technical discussions or piece of writing may include words which are never used outside the subject or field in question. If you do not know the subject, you will not understand what is said or written, even if English is your mother tongue. The vocabularies used in science and technology are very large, and in English they include many semitechnical words which are used in unfamiliar ways so that their new meanings must be learned.
