In that part of test, we are asked to write a short essay according to a given picture. In the picture, a pair of parents are facing with a computer on the first floor in an apartment. On the screen is a sentence of irony, ‘Dear son, How is your life going on the second floor? We miss you so much. ’Obviously, the picture reflects the common problem in our daily life. Technology has made us and close relatives and friends more distant.We can’t deny that the great benefits brought about by the progress on science and technology is hided in every corner of the world. Modern communication tools such asmobiles and QQ make it possible to send message in a handy way. The Internet enables a pupil to accomplish a university graduation thesis. Powerful networking information storage makes incalculable social activity in an orderly way. Sophisticated scientific techniques even help human to explore other planets. Anyway,the finding of the second earth may give human a newaccomadation after the earth is destroyed. That sounds not bad. As we can see, the rapid development of science and technology has brought great changes to our life. However, some of the influence it takes is not so optimistic. Just like the example I reffered at the beginning. Communicating through social networking web site is becoming a threaten to people’s real life. Against to it’s original willing, we gradually fade out in the crowd. Despite this, children lack essentialinterpersonal skills. Those who indulge in I pad or I phone often isolated and being cut off from the outside world. They tend to be more introverted, self-centered and withdrawn. From another point of view, the technique makes using tools on a large scale become a consequent tendency. You must hear of the industrial revolution which caused two job cuts over the whole world. Nowadays, the bad influence may even worse. The mature assembly line work is controlled by automatic machine.Thereupon, a large amount of workers get unemployed. It is not benefit to stabilize society. Some of scientific inventions have also done great harms or disasters to mankind. And advanced technology can be easily manipulated by irresponsible persons or countriees.It is just easy to think of something, but difficult to give down-to-earth execution. We should avoid the negative effects while enjoying the great convenience. I believe that, once we try, we are bond to keep the balance of advantages and disadvantages.关于科技的英语演讲稿范文4The development of science and technology makes our life more comfortable and convenient.However, scientists have created many problems, which are not easy to be resolved,such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions. Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before. Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rocketsand space shuttles can help us realize the dream of space travel. Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable. However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-madesatellite.Industrialization is making natural resources become scarce. Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.关于科技的英语演讲稿范文5Science and art are the obverse and reverse of Nature's medal; the one expressing the eternal order of things, in terms of feeling, the other in terms of thought.Science has long had an uneasy relationship with other aspects of culture. Think of Galileo’s 17th-century trial for his rebelling belief before the Catholic church or poet William Blake’s harsh remarks against the mechanistic worldview of Isaac Newton. The schism between science and the humanities has, if anything, deepened in this century.Until recently the scientific community was so powerful that it could afford to ignore its critics--but no longer. As funding for science has declined, scientists have attacked “anti-science” in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl Sagan of Cornell University.Defenders of science have also voiced their concerns at meetings such as “The Flight from Science and Reason,” held in New York City in 1995, and “Science in the Age of (Mis) information,” which assembled last June near Buffalo.Anti-science clearly means different things to different people. Gross and Levitt find fault primari ly with sociologists, philosophers and other academics who have questioned science’s objectivity. Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview.关于科技的英语演讲稿范文6You might never fail on the scale I did, but some failure in life is inevitable. It is impossible to live without failing at something, unless you live so cautiously that you might as well not have lived at all – in which case, you fail by default.Failure gave me an inner security that I had never attained by passing examinations. Failure taught me things about myself that I could have learned no other way. I discovered that I had a strong will, and more discipline than I had suspected; I also found out that I had friends whose value was truly above the price of rubies.The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive. You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more than any qualification I ever earned.关于科技的英语演讲稿范文7I was given the job of escorting him back to the Underground Station afterwards, and this man whose life had been shattered by cruelty took my hand with exquisite courtesy, and wished me future happiness.And as long as I live I shall remember walking along an empty corridor and suddenly hearing, from behind a closed door, a scream of pain and horror such as I have never heard since. The door opened, and the researcher poked out her head and told me to run and make a hot drink for the young man sitting with her. She had just had to give him the news that in retaliati on for his own outspokenness against his country’s regime, his mother had been seized and executed.Every day of my working week in my early 20s I was reminded how incredibly fortunate I was, to live in a country with a democratically elected government, where legal representation and a public trial were the rights of everyone.Every day, I saw more evidence about the evils humankind will inflict on their fellow humans, to gain or maintain power. I began to have nightmares, literal nightmares, about some of the things I saw, heard, and read.And yet I also learned more about human goodness at Amnesty International than I had ever known before.关于科技的英语演讲稿范文8Now, I am not going to stand here and tell you that failure is fun. That period of my life was a dark one, and I had no idea that there was going to be what the press has since represented as a kind of fairy tale resolution. I had no idea then how far the tunnel extended, and for a long time, any light at the end of it was a hope rather than a reality.So why do I talk about the benefits of failure? Simply because failure meant a stripping away of the inessential. I stopped pretending to myself that I was anything other than what I was, and began to direct all my energy into finishing the only work that mattered to me. Had I really succeeded at anything else, I might never have found the determination to succeed in the one arena I believed I truly belonged. I was set free, because my greatest fear had been realised, and I was still alive, and I still had a daughter whom I adored, and I had an old typewriter and a big idea. And so rock bottom became the solid foundation on which I rebuilt my life.关于科技的英语演讲稿范文9Amnesty mobilises thousands of people who have never been tortured or imprisoned for their beliefs to act on behalf of those who have. The power of human empathy, leading to collective action, saves lives, and frees prisoners. Ordinary people, whose personal well-being and security are assured, join together in huge numbers to save people they do not know, and will never meet. My small participation in that process was one of the most humbling and inspiring experiences of my life.Unlike any other creature on this planet, humans can learn and understand, without having experienced. They can think themselv es into other people’s places.Of course, this is a power, like my brand of fictional magic, that is morally neutral. One might use such an ability to manipulate, or control, just as much as to understand or sympathise.And many prefer not to exercise their imaginations at all. They choose to remain comfortably within the bounds of their own experience, never troubling to wonder how it would feel to have been born other than they are. They can refuse to hear screams or to peer inside cages; they can close their minds and hearts to any suffering that does not touch them personally; they can refuse to know.I might be tempted to envy people who can live that way, except that I do not think they have any fewer nightmares than I do. Choosing to live in narrow spaces leads to a form of mental agoraphobia, and that brings its own terrors. I think the wilfully unimaginative see more monsters. They are often more afraid.What is more, those who choose not to empathise enable real monsters. For without ever committing an act of outright evil ourselves, we collude with it, through our own apathy.One of the many things I learned at the end of that Classics corridor down which I ventured at the age of 18, in search of something I could not then define, was this, written by the Greek author Plutarch: What we achieve inwardly will change outer reality.关于科技的英语演讲稿范文10So given a Time Turner, I would tell my 21-year-old self that personal happiness lies in knowing that life is not a check-list of acquisition or achievement. Your qualifications, your CV, are not your life, though you will meet many people of my age and older who confuse the two. Life is difficult, and complicated, and beyond anyone’s total control, and the humility to know that will enable you to survive its vicissitudes.Now you might think that I chose my second theme, the importance of imagination, because of the part it played in rebuilding my life, but that is not wholly so. Though I personally will defend the value of bedtime stories to my last gasp, I have learned to value imagination in a much broader sense. Imagination is not only the uniquely human capacity to envision that which is not, and therefore the fount of all invention and innovation. In its arguably most transformative and revelatory capacity, it is the power that enables us to empathise with humans whose experiences we have never shared.One of the greatest formative experiences of my life preceded Harry Potter, though it informed much of what I subsequently wrote in those books. This revelation came in the form of one of my earliest day jobs. Though I was sloping off to write stories during my lunch hours, I paid the rent in my early 20s by working at the African research department at Amnesty International’s headquarters in London.There in my little office I read hastily scribbled letters smuggled out of totalitarian regimes by men and women who were risking imprisonment to inform the outside world of what was happening to them. I saw photographs of those who had disappeared without trace, sent to Amnesty by their desperate families and friends. I read the testimony of torture victims and saw pictures of their injuries. I opened handwritten, eye-witness accounts of summary trials and executions, of kidnappings and rapes.Many of my co-workers were ex-political prisoners, people who had been displaced from their homes, or fled into exile, because they had the temerity to speak against their governments. Visitors to our offices included those who had come to give information, or to try and find out what had happened to those they had left behind.I shall never forget the African torture victim, a young man no older than I was at the time, who had become mentally ill after all he had endured in his homeland. He trembled uncontrollably as he spoke into a video camera about the brutality inflicted upon him. He was a foot taller than I was, and seemed as fragile as a child.关于科技的英语演讲稿范文。

科技的英语作文篇1technology is a necessary force in modern life. we use technology to develop economy, change our life and quicken the pace of development. without it,we might still stay in a poor society. we might have no tvs, no computers and even no lights. we might have to work by hands instead of by machines and read many books to gain new knowledge instead of XXX use of computer nets. it's believed that technology improves our life.but technology is not always a positive force in modern life. if it is not used in the right way, it may be harmful and even dangerous to people. for example,as a result of advanced technology, computer viruses have been made by some people with personal purposes,and obviously everyone knows what harm they do. we can see that under the influence of the negative effect of technology,our society may be faced with a great danger.so we should make use of the positive force of technology to develop our modern life and reduce its negative effects.科技的'英语作文篇2Nowadays, there is general trend that people engaging in technological revolutions. Nevertheless, a question has been raised, “how did the science change our living conditions”To begin with, the science can help us to relieve excessivestress and tension by providing a temporary escape from a day-to-day life. In a world that has increasingly focused on turning everyone into millionaire, to cope with the current social trend, people crave being actively involved in the larger world and widening circles. Work-related stress, for example, has become a major problem which plagues all of modern people. In the most cases, the TV or computer, which were invented by new technology in the 20th century, can not merely help us lessen stress accumulated from an individual's demanding work life but are also fun to indulge in, is a sound and viable plan.In addition to eliminating people’s tension, the development of telephone and internet has improved our life styles. In other words, the science can allow us to meet friends of diverse background by an interesting and effective means. Especially, the age of a student or, better yet, the stage of the personal development of a student has to be considered when they have no leisure time and opportunity to widen circles and learn how to interact socially and behave in a group of their peers.Finally, it is undeniable that continuously developing technologies have brought tremendous benefits, especially in learning area. Learning has in many ways become easier than has ever been before. Take learning English for example, In the past, few students owned tape recorders, and learning materials were scarce as well. But today, tape recorders get more and more inexpensive, and diversified learning materials are readily available. On the other hand, new devices, such as MP3 or MD players, are offered in market, and relevant learning materials (MP3 files) are easily and freely downloadable from the Internet.Admittedly, science revolution has some negative effects under certain circumstances. For instance, the new technologycan harm our environment. However, after balancing all the pros and cons, the above-mentioned disadvantage seems to be minor. 科技的英语作文篇321st century is the century of technology. Today, technology is everywhere. We often use several technologies ,such as computer and phone. These technologies make easier life for us.With the development of technology and science, people are getting richer. Computer will go into every household. Computer can help us to do many things, such as playing games, designing and making us easier to do things.With today's technology, the phone can do many things, such as taking photos and sending the e-mail on the phone. We needn’t write a letter. We just need to make a phone call, so you can know more and more from your friends or family.With better and faster development of science and technology people can live better. If we do not have science and technology, our life will become even worse, the world cannot become beautiful. Without technology, there would be no technology life科技的英语作文篇4Several reasons account for the change. Firstly, we are in the information age today. Computers are useful in editing and data processing, make it easier for people to communicate with each other and provide all sorts of information. Secondly,computer skills can be a competitive edge for job hunter, which stimulates students' interest in computers and encourages them to have a good command of them. Finally,as the price of computers drops sharply recent years, more and more students can afford them.But some problems also arise,liking wasting students’time and having negative effect on studies. Therefore, we, as students,should always keep in mind that we should use computer in an appropriate way.科技的英语作文篇5Technology is a necessary force in modern life. we use technology to develop economy, change our life and quicken the pace of development. without it,we might still stay in a poor society. we might have no tvs, no computers and even no lights. we might have to work by hands instead of by machines and read many books to gain new knowledge instead of XXX use of computer nets. it's believed that technology improves our life.But technology is not always a positive force in modern life. if it is not used in the right way, it may be harmful and even dangerous to people. for example,as a result of advanced technology, computer viruses have been made by some people with personal purposes,and obviously everyone knows what harm they do. we can see that under the influence of the negative effect of technology,our society may be faced with a great danger.So we should make use of the positive force of technology to develop our modern life and reduce its negative effects.科技的英语作文篇6May 1st Sunday Fine.It was fine today,Lily and I went to visit the Science Museum.It is about two kilometers away from our homes, so we decided to go there by bike.We set off at 8 o'clock.At the museum we saw a lot of interesting things.We could operate some equipment.There we met many classmates and friends.We thought we had learned a lot and were more interested in science.At half past eleven we left the museum for home.We enjoyedourselves in the museum today.5月1日星期日晴今天是个好天气,我和丽丽去科技馆参观。

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

A relatively rare event or quite shocking events also can be easy to become the center of network public opinion. And the reason of network public opinion happening is that the rapid development of the network makes the rapid dissemination of information. Every small events are likely to become the center of network public opinion. And the second reason is many people have a strong sense of Equal and justice. And the network is a very good platform to make their speech attention and recognition. So that many people like to go to internet to make comments on it. In the course of time the network public opinion has become more and more frequent But the emergence of the network public opinion brings different influence.First of all is the good work public opinion can supervise the false, unfair events,officials, play a supervisory role.But on the other hand, The network of public opinion also caused a lot of bad influence.Such as Human flesh search also easy to cause the invasion of privacy.科技英语范文:Is Science DangerousThe rapid development of science and technology has brought about great changes to human life, including great harms and disasters .Then people enter into endless argument about whether science is dangerous or not.So many examples can be figured out to prove the danger of science. Advanced technology can be easily manipulated by irresponsible persons as well as terrorist. Such as the Disaster 911, airplanes fly into buildings, fire burning, huge structures collapse, a lot of victims such as intellectual and business elites were sacrificed. Besides, As technology becomes more powerful day by day , we'll be complacent and lazy. Increased dependency on modern tools like calculators has reduced on our creativity. Students can’t solve a very simple mathematical equation without using a calculator. This affects the way these students uses their brains and reduces on the level of creativity.Just like the saying goes that every coin has two sides. However, it ‘s obvious that we make the decision to choose which side. After 911, people condemn the terrorist not airplays. Student who got low marks should rethink his carelessness and laziness but not pass the buck to the calculator.Any way, There is no dangerous science, but dangerous and irresponsible people. We are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. Actually, the key lies in the user. Moralities such as responsibility, diligence and goodness should never be lost in our heart. Otherwise , the world would be full of danger even we turn back to the stone age.科技英语范文:The impact of technology on personal communicationNowadays, with the rapid development of science and technology, people’s life takes on a brand new look, especially the communication.No one can deny that we enjoy the convenience of hi-techproducts such as mobile phones and computers. They have enormously changed the ways of communication in shortening the distance between people as well as making instant contact possible. The speeding-up mobile technology has efficiently promoted the dream of “global village”.However, each coin has two sides. Since mobile technology has progressed rapidly, there occurs some lamentable phenomenon. The high technology make our communicationmoreconvenient, but it doesn’t mean科技英语范文:高科技The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions.Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before.Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel.Modern medicine prolongs peoples life and relieves patientsof sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable.However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce.Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.。

科学技术英语作文篇1"She has this thing where she goes to a movie theater, watching a horror movie and there was a wolf howling in the background.” University of Cambridge zoologist Arik Kershenbaum, talking about his collaborator Holly Root-Gutteridge, a biologist at Syracuse University. She said to herself, ‘Well, that's wrong. That's clearly a European wolf and not a North American wolf like it should be in the scene.'"Slight variations in the way we speak allow us to tell whether someone is from Boston or New York just by listening to them. The same turns out to be true for the animals known as canids, which includes wolves, dogs and coyotes. They all howl to communicate—but those howls vary. Canids can tell which howls belong to their known associates and which belong to strangers.So Kershenbaum and Root-Gutteridge decided to categorize the howls of different canids around the world. Together with colleagues, they compiled recordings of more than 2,000 canid howls, including European wolves, Mexican wolves, arctic wolves, dingoes, coyotes, golden jackals, domestic dogs, New Guinea singing dogs, and more. A computer program sorted the howls into different types. The study was published in the journal Behavioral Processes. [Arik Kershenbaum et al, Disentangling canid howls across multiple species and subspecies: Structure ina complex communication channel]Based on the analysis, canids use 21 different kinds of howls to communicate. If you think of the howls as words, then all canids have the same vocabulary—but each species or sub-species has its own unique dialect. Some words are more common in one dialect, while other words are more common in another dialect and so on. By matching dialect with species and geography, researchers could monitor endangered species, like red wolves, just by listening.AK: "Being able to distinguish between the howls of a coyote and the howls of a red wolf opens the possibility for techniques of passive monitoring, passive population monitoring, using acoustics."Meanwhile, ranchers have tried to broadcast specific howls to discourage grey wolves from feasting on their livestock, but it's never been successful.AK: "Because we don't really know what message we're conveying to the wolves when we play back an arbitrary howl. For all we know, we could be playing back a howl that means come and eat, there's lots of interesting food over here."The research could thus finally bring peace to the conflict between ranchers and wolves, by finally speaking to the predators in their own language.—Jason G.

People living in the 18th or 19th centuries would never imagine the advanced household appliances we are now able to enjoy. Every aspect of our lives, for instance, in the field of medicine or agriculture has witnessed great improvements through the application of science.However, many people complained that science has also brought disasters to human life. Some evil scientists have used their knowledge to do some illegal things. They may use science for the creation of weapons to destroy thousands of lives in wars. They might also use their knowledge to produce drugs to make a lot of money for themselves.Generally speaking, science has provided us with many valuable things. But if used wrongly, it can also lead toharm. We should try to keep science under control and put it to the best use of mankind.科技的英语作文3Science and technology change our life.With the rapid development of science and technology, our daily life has been changed a lot. New technological inventions begin to play an essential role, for example, the robot can help us clean up and finish much homework.

科技英语作文篇1Technology has turned this world into a different one full of wonders, some of them being too good to be true. For example, mobile phone is playing an important role in our social and professional lives, whereas the Internet has connected people at every corner on the planet and beyond. As a consequence, telecommuting may soon become a more common way of working as more people are doing part of their jobs from home. And so what? Actually people are no closer to feeling happy in various respects because such technological developments are destroying many basic values of simple and easy lifestyles. Computers in particular have made life less emotional since the more time people use the Internet, the less time they spend with human beings.In sum, there are reasons to be worried about what will become of mankind as a whole facing an increasingly complex world in which they may enjoy all the conveniences of life and yet they do not feel any happier or wiser. Who knows that over-dependence on modern technology could not mean the beginning of the end of human sparks of creativity, spirit, compassion, love and understanding and other good things about a simple and easy life. In making peoples lives more enjoyable but more complex, technology seems as if sendingplenty of blessings from heaven as well as sending plenty of evils from hell.科技英语作文篇2Why doesn’t the fish sleep?

关于科技的英语作文精选5篇科学技术是社会进展的原动力。
没有他们,人类社会的进展永久无法从原始社会到现代社会。
下面给大家共享一些关于科技的(英语(作文)),盼望对大家有关心。
关于科技的英语作文1In the modern time, the growth of technology is increasingly developed. More and more people don’t use their brains when there is no need to use other instruments. Too much people use technology so that people are lazier and less healthy than before. They rely on technology too much.Some believe that modern technology shorten the distance of human. For instance, people all use cellphone to call friends or family, or computer to search information, or use , MSN, twitter, blog etc. These modern instruments shorten the distance between human.However, others think that it’s just the reverse. Technology makes people use less face-to-face communication. The contact in real life is less and less. People do less interaction to each other. In the long term, people will get depressed without enough communication.As far as I’m concerned, modern technology provides convenience to people. It makes people easily to get information. Only could we use it correctly, it does much contribution to us.关于科技的英语作文2Science and technology have been bringing human beings tremendous benefits. Thanks to science and technology, we now live comfortably and conveniently in houses furnished with air conditioners, refrigerators, washing machines and televisions etc. Thanks to science and technology, we can eat fresh vegetables at the year round. Thanks to science and technology, we can travel long distances in the fraction of a second on planes, trains and cars. Thanks to science and technology, we wear clothes with synthetic materials which can not easily be worn out.However, science and technology have atso brought us a lot of disasters. First, because of the many breakthroughs in the field of medicine, people are now living much longer than they used to. As a result, the population of the world is increasing, causing lots of problems. Second, because of the development of industry, lots of the wastes from factories pour into the air and rivers, causing pollution of all kinds. Third, some terrorists are using science and technology against mankind. They use biological, chemical and unclear weapons to threaten world peace...So its urgent that we find ways to solve these problems. But we should not stop the development of science and technology because of these disasters they bring, just as we should not give up eating for fear of choking. In addition, we should make some rules to regulate our actions. As long as we use science and technology in a proper way, they may bring us even more benefits.关于科技的英语作文3Here is a difference between science andtechnology.Science is a method of answering theoreticalquestions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools,techniques, and procedures for implementing the findings of science.Another distinction between science and technology has to do with the progress in each. Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth with the highest degree of accuracy and certainty, cannot pay heed to their own or other peoples likes or dislikes, or to popular ideas about the fitness of things. What scientists discover may shock or anger people--as did Darwins theory of evolution. But even an unpleasant truth is more than likely to be useful; besides, we have the option of refusing to believe it! But hardly so with technology;we do not have the option of refusing to hear the sonic boom produced by a supersonic aircraft-flying overhead; we do not have the option of refusing to breathe polluted air. Unlike science, progress in technology must be our slave and not the reverse. The legitimate purpose of technology is to serve peopie--people in general, not merely some people; and future generations, not merely those who presently wish to gain advantage for themselves.We are all familiar with the abuses of technology. Many people blame technology itself for widespread pollution, resource depletion and even social decay in general--so much so that the promise of technology is obscured. That promise is a cleaner and healthier world. If wise applications of science and technology do not lead to a better world, what else will?关于科技的英语作文421st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better.First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently.Also, internet is another useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. The internet leads us to a place where we can find unlimited information and resources. It makes our life much easier and better.The last technology is cellphone. Nowadays, many people have a cellphone. But it just appears on the market for about 10 years. It is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. Also, we can communicate with others by making a phone call instead of sending letters. It is very fast and useful way to communicate.In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future.关于科技的英语作文5The advent of modern technology brings a substantial impact on the whole world. It not only boosts the economy, but also changes the people’s conception on the world. It also increases global communication among countries. In my opinion, modern technology is creating a single world culture in that such technology as computer and internet is bringing people together and making the world get smaller.First of all, modern technology promotes the globe to frequently use one language. The invention of computers and Internet promotes English to be a global language and dominate in the communication worldwide. Since language is the agent of culture, the worldwide use of English fosters more and more minds thinking alike.Besides, the development of the internet brings peo ple’s life style into uniform. The availability of Internet makes people have a lot in common, such as access to information, online shopping or payment. People from all over the world are doing the same thing each day on the Internet, and their living habit is becoming closer and closer with each passing day.Based on the points discussed above, it is obvious that modern technology is creating a single world culture.关于科技的英语作文精选5篇。

英语科技文8篇
英语科技文8篇1.《蚕丝制作》As is displayed in the first diagram, the life cycle of the silkworm can be categorized into 4 main stages. First, the life of the silkworm starts from eggs propagated by the moth, and it takes 10 days for each egg to become a silkworm larva that feeds on mulberry leaves. Silkworm larva continues to grow in 4 to 6 weeks, then wrapping itself with silk thread to construct a cocoon in the next 3 to 8 weeks. A moth can be produced from the cocoon in 16 days. The life cycle begins again from then on. Focusing on the second diagram, it illustrates the 5 main steps of the procedure of producing silk cloth. Well generated cocoons will be selected firstly. Before the silk thread can be unwound, cocoons have to be boiled in hot water. One cocoon can produce approximately 300 to 900 metres of silk thread. The unwound thread will be dyed afterwards to be weaved into silk cloth. Overall, the two diagrams reveal the stage of producing cocoons in the life cycle of the silkworm can be used to make silk cloth through 5 simple steps.2.《户外取水》The chart describes how water is obtained outdoors. According to the figure, the first step of obtaining water outdoors is to find a hole with green plants on its bottom. Next, remove the green plants in the middle and put a container there. Then, cover the hole with a plastic sheet and place two stones on both ends of it to secure its position. A third stone is laid on the middle of the plastic sheet so that the middle part is also the lowest part. When the sun shines on the green plants in the hole, water evaporates from these plants. The vapor rises up and then coolsdown to form water drops on the plastic sheet. When there is more and more water, it flows along the sheet to accumulate on the lowest part. Finally, water falls down into the container directly under the middle stone. Thus, water is collected successfully through evaporation from green plants.3.《房屋不同季节的构造》As is displayed in the flow chart, the principles of insulation in cool and warm climate respectively differ to a large extent. As to the situation of cool climate, we adopt the high-angled roof in order to be nearly parallel with the direction of the sun so that the direct exposition to the heat of sun is lessened as much as we can. By this, the temperature of the materia l won’t fluctuate within a large range. Meanwhile, thermal building material could enhance the heat storage insulation, preventing outflow, thus reduction of heat. Adversely, in warm climate, reflective building material is indispensable with overhands for shade. The direction of the roof is almost vertical to the direction of the sun to lead to external insulation reflection. By this, ventilation would result in the removal of heat storage rather than reduction. Through the different working principles of ventilation, we are fascinated by the masterpieces of modern science and technology.4.《超市建造地点选择》As is unfolded in the map, Place M and N have their unique pros and cons as to the place for building the supermarket. First of all, Place N is located in the urban area of the G town, which may have more population and business. This advantage is incomparable with Place M. What’s more, Main road runs across the center area with convenience in traffic and logistics for the market afterwards. However, the place is equally far away from the neighborhood and the suburb area and cannot attract theresidents inthe outskirts. As a double-edged sword, Place M is more specifically customer-oriented. In spite of its comparably remote location with Place N, it would attract more customers in the outskirts, for they are reluctant to make a long trip for shopping. On the other hand, the train line nearby will also bring convenience in traffic to the urban-dwellers. Situated to the north-west of Place N, Place M is near the A and B Town with total population of 23 million, far outnumbering the overall population of D and E town, with 12 million. What’s worthy of being mentioned is that fierce competition in Place N and probable monopoly in Place M should also be taken into account when building the supermarket.5.《玻璃的再生》As is displayed in the flow chart, the recycling process of glass is really a complex one. The overall process can be categorized into 3 stages. First, glass products in various forms are gathered in the Collection point, so that they are easily transported by special trucks or vans to the Cleaning plant, where they get sterilization by high-pressured water. There are three different channels in the Recycling plant, namely Brown, Green and Clear, which represent the colors of glass. After recycled in the furnace, glass products are melted into recycled liquid glass. Mixed with new liquid glass, the compound is finally moulded into solid glass, which, afterwards, will be sent to various customer supermarkets for selling. Thus, the glass will go to the customers for different purposes. Through a brief introduction of the circle of glass recycling, we come to realize that recycling plays a vital role in environmental protection and ecological preservation.6.《化肥的制作》As is shown in the flow chart, the process of recycling organic waste to produce compost is really a complex one. The whole process can be categorized into five stages. First of all, prepare a plastic container which has four holes for ventilating the air. There is a rule when putting waste into the container, food at the bottom within 15 centimeters high, grass at the middle and newspaper at the top within 15 centimeters high altogether, in order to make a optimum environment for different bacteria reproducing. In the following stage, we can witness nitrogen and water being put into the container. What's worth mentioning is that water is only added in a hot weather. Next, heat the waste and let the bacteria reproduce fastly, with which the organic waste can be decomposed and became garden fertiliser after 6 months. Subsequently, we can carry the compost out and move it to the garden, thus a new recycling can begin. In conclusion, using this way to turn the organic waste into garden fertiliser is environmentally friendly. By enlarging the number or volume of the container, we can dispose more waste at the same time.7.《咖啡的制作》The diagram shows the stages in the process of making chocolate. Chocolate comes from the cacao tree, which is grown in parts of South America, Africa and Indonesia. The tree produces large red pods which contain white cocoa beans. Firstly, when the pods are ripe, they are harvested, the beans are removedand they are fermented for several days in large wooden boxes. During the fermenting process, the beans turn brown. Next, the brown beans are spread in the sun to dry. They are then put in large sacks and transported by train or lorry. After this, thebeans are taken to a chocolate factory where they are roasted in an oven at temperatures of between 250 and 350 degree Celsius. After being roasted, the beans are crushed and the outer shell is removed. This part is not needed for making chocolate. Finally, the inner part of the bean is pressed and liquid chocolate is produced.8. 《砖块的制作》The process by which bricks are manufactured for the building industry can be outlined in seven consecutive steps. First the raw material, clay, which was just below the surface of soil in certain clay-rich areas has to be dug up by a digger. Then the lumps of clay are placed on a metal grid in order to break up the big chunks of clay into much smaller areas, which fall through the metal grid onto a roller, whose motion further segregates the bits of clay. Sand and water are added to make a homogenous mixture, which is then either formed in moulds or cut into brick-shaped pieces by means of a wire cutter. Those fresh bricks are then kept in a drying oven for at least 24 and a maximum of 48 hours, several dozens if not hundreds of bricks at a time. The dried bricks are then transferred to a so-called kiln, another type of high temperature oven. First they are kept at a moderate temperature of 200 ℃-1300 ℃ . This process is followed by cooling down the finished bricks for 48 to 72 hours in a cooling chamber. Once the bricks have cooled down and have become hard, they get packaged and delivered to their final destination, be it a building site or storage.。

探索发现:科学家发现奇特系外"钻石"行星群
An exoplanet, called WASP-12b which is about 1,200 light years from Earth and 1.4 times the mass of Jupiter has been considered suitable for life existence, although a little hot. And its sibling planets could even be made of diamonds, according to new research findings.
最新研究结果显示,一颗名为WASP-12b、距离地球1200光年、质量为木星1.4
倍的系外行星适合生命存在,尽管热了一点。
而与其同属一个星系的情况更甚:它们有可能由钻石构成。
A team led by researcher Nikku Madhusudhan of Princeton University and scientist Joe Harrington of the University of Central Florida monitor WASP-12b during one of its orbits, particularly in the instants before it passed behind its home star. In those brief moments, the light from the star would flow through the planet's atmosphere, allowing astronomers to study the wavelengths produced and infer the atmosphere's chemical composition.
由美国普林斯顿大学的研究员尼库马杜苏丹和佛罗里达中部大学的科学家乔哈林顿
领导的一个研究小组检测WASP-12b的一次绕轨运行情况,特别是在它从其母恒星后面经过的那一刻。
在这一刹那,恒星发出的光会穿透行星的大气,天文学家得以研究产生的波长,并推断行星大气的化学成分。
They found some exoplanets, WASP-12b included, have carbon-rich chemistry: Some have atmospheres with a carbon-to-oxygen ratio of about 0.5. As for WASP-12b, however, there was more than twice the concentration of carbon as usual and almost 100 times more methane than expected.
他们发现,一些包括WASP-12b在内的系外行星具有碳浓度高的化学特性,即它们大气中的碳氧比率约为0.5。
不过,WASP-12b的碳浓度要比通常情况高出一倍多,而且甲烷的浓度几乎是预计的100倍。
That has big implications for extraterrestrial biology, since life is based on carbon, and methane - which is made up of carbon and hydrogen - is a byproduct of metabolism. The planet's carbon-heavy atmosphere could retain heat and light, providing energy for life to get started and thrive. That life would have to survive on comparatively little oxygen and water, and would have to be very tolerant of methane.
这对于地外生命学来说意义重大。
因为生命建立在碳的基础上,而由碳和氢构成的甲烷是新陈代谢的副产品。
大气中高浓度的碳可以留住光和热,为生命的出现和茁壮成长提供能量。
这些生命要再氧气和水相对较少的环境下生存,而且要能够忍受甲烷。
As for some of the planets formed along with WASP-12b, they could easily be smaller, with rocky formations made not of silica, like Earth's, but of graphite or - given enough time and enough pressure - precious diamonds.
而和WASP-12b一起形成的另外一些行星很可能体积更小,岩层不像地球那样由硅石构成,而是由石墨或者——如果有充足的时间和压力——钻石这样的珍贵材料构成。
