Title: The Impact of Technology on Our LivesIn the modern era, the influence of technology is ubiquitous and profound. It has transformed the way we live, work, and interact with one another. As a high school student, I have witnessed firsthand the remarkable changes that technology has brought to my life and the world around me.Growing up in a digital age, I have always been surrounded by gadgets and software that make life more convenient. The smartphone, for instance, is not just a communication device but a gateway to information and entertainment. With a simple tap, I can access the vast knowledge of the internet, watch videos, play games, and stay connected with friends and family. This level of connectivity was unimaginable to previous generations.The educational landscape has also been revolutionized by technology. Online courses and digital textbooks have made learning more accessible and flexible. As a student, I can now learn at my own pace, review materials as needed, and even interact with teachers and classmates from the comfort of my home. This has been particularly beneficial during times when physical attendance at school is not possible, such as during the COVID19 pandemic.Moreover, technology has had a significant impact on the job market.

As a high school student, I am excited about the possibilities that technology presents, but I also recognize the need to navigate its complexities responsibly.翻译：标题：科技对我们生活的影响在现代时代，科技的影响无处不在且深远。

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.

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。

我的科普作品作文英语Title: The Wonders of the Universe: Exploring the Cosmos。

Have you ever gazed up at the night sky and wondered about the vastness of the universe? The cosmos, with its countless stars, galaxies, and mysteries, has fascinated humanity for centuries. In this essay, we will embark on a journey through the wonders of the universe, exploring its marvels and expanding our understanding of the cosmos.Let's begin our journey by contemplating the stars. Stars are born from vast clouds of gas and dust, undergoing a process known as stellar formation. Within these stellar nurseries, gravitational forces pull matter together, causing it to heat up and ignite nuclear fusion, the process that powers stars. From massive, luminous giants to small, dim dwarfs, stars come in a variety of sizes and colors, each contributing to the cosmic tapestry in its own unique way.Among the stars, our own Sun shines brightly, providing warmth and light to our planet. But beyond our solar system lie billions of other stars, many with their own retinues of planets, moons, and other celestial bodies. Recent discoveries of exoplanets – planets orbiting stars outside our solar system – have sparked excitement among astronomers, raising questions about the possibility oflife beyond Earth.Galaxies, vast conglomerations of stars, gas, and dust, are another fascinating aspect of the universe. From the majestic spiral arms of galaxies like the Milky Way to the irregular shapes of dwarf galaxies, these cosmic structures come in a variety of forms. At the heart of many galaxies lie supermassive black holes, gravitational behemoths that devour matter and emit powerful jets of energy. These enigmatic objects play a crucial role in shaping the evolution of galaxies and the cosmos at large.As we venture further into the cosmos, we encounter phenomena that challenge our understanding of the universe.Black holes, for instance, are regions of spacetime where gravity is so intense that nothing, not even light, can escape. Despite their mysterious nature, black holesprovide valuable insights into the fundamental laws of physics, offering a window into the nature of space, time, and gravity.The universe is also home to exotic phenomena such as supernovae, the explosive deaths of massive stars, and gamma-ray bursts, the most energetic events in the cosmos. These cataclysmic events release staggering amounts of energy, shaping the landscapes of galaxies and seeding the cosmos with heavy elements essential for the formation of planets and life.Cosmology, the study of the origin, evolution, and fate of the universe, seeks to unravel the mysteries of cosmic history. Scientists employ a variety of tools and techniques, from powerful telescopes to sophisticated simulations, to probe the deepest reaches of space and time. By studying the cosmic microwave background radiation, the afterglow of the Big Bang, cosmologists have piecedtogether a detailed narrative of the universe's birth and evolution over billions of years.Yet, for all our progress, the universe remains a source of wonder and awe, inviting us to ponder the mysteries that lie beyond our current understanding. From the smallest subatomic particles to the vast cosmic web of galaxies, the universe continues to inspire curiosity and exploration. As we gaze up at the stars, let us marvel at the beauty and complexity of the cosmos, knowing that there is still much left to discover and understand.In conclusion, the universe is a vast and wondrous place, filled with mysteries waiting to be explored. From the birth of stars to the evolution of galaxies, from the enigmatic depths of black holes to the explosive finales of supernovae, the cosmos offers a rich tapestry of phenomena for us to investigate. Through the lens of science, we can deepen our appreciation of the universe and unlock its secrets, expanding our understanding of the cosmos and our place within it.。

科技改变英文作文英文：Technology has had a tremendous impact on our lives, changing the way we live, work, and communicate. From smartphones to social media, technology has transformed the way we interact with each other and the world around us.One of the biggest ways technology has changed ourlives is through the rise of social media. Platforms like Facebook, Twitter, and Instagram have made it easier than ever to connect with friends and family, share photos and updates, and even meet new people. This has had a profound impact on our social lives, allowing us to stay connected with people even when we can't be physically together.Another way technology has changed our lives is through the rise of remote work. With the advent of tools like Zoom and Slack, it's now possible to work from anywhere in the world, as long as you have an internet connection. This hasopened up new opportunities for people who live in rural areas or who have disabilities that make it difficult to commute to a traditional office.Of course, technology has also had its downsides. The rise of social media has led to concerns about privacy and the spread of misinformation, while remote work can lead to feelings of isolation and burnout. It's important for us to be aware of these issues and to take steps to mitigatetheir impact on our lives.Overall, I believe that technology has had a netpositive impact on our lives, but it's important for us to use it responsibly and to be mindful of its potential drawbacks.中文：科技对我们的生活产生了巨大的影响，改变了我们的生活方式、工作方式和交流方式。

Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered, or died. Now, many experts believe, humans are imperiling their own ecological niche with the threat of global warming. The vaporous by-products of civilization, in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues, it could alter climate patterns worldwide-thawing glaciers, boosting sea level, scorching plains into deserts, and shifting vegetation zones.（1）生命在这个星球上已经发展了近四十亿年。

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现：地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明，地球上的许多生态系统都达不到标准。

The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统（包括干净的水源、纯净的空气以及稳定的气候）正遭受破坏。

Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。

Teach Predictions for 20101. Finally, Apple Unveils the TabletOfficially, Apple has never said a word about making a tablet computer. Yet for months, everyone in tech has been talking and writing and arguing about the Apple tablet as if it's already here. The product has already received more press than most products that actually exist. Bloggers debate its faults and flaws, its strengths and Shortcomings--such is life in the weird and wonderful world of Apple. And this does not happen by accident. Apple orchestrates this stuff. It did the same thing with the iPhone, remember? For a year before the prodtict was unveiled, rumors circulated and fake prototype photos popped up all over the place. Ifs all about creating hype, and wrapping a product in a cloud of mystery and drama, so that by the time you do unveil it people are dying to buy it just tosee what all the fuss is about.The great thing about Apple, however, is that usually the products live up to the hype. Certainly the iPhone has. Arguably, it is the single most important tech product of the past decade. Will the tabletbe as profound? We think it will be. Amazon's Kindle has pioneered the market for a portable reading device. But Kindle is far from perfect. Our bet is that Apple enters this space the way it did with the iPod and iPhone: it lets others do the pioneering work and make all the mistakes, then comes along with a product that blows the predecessors away. Better design. Better build quality. Better service. And a user interface experience that’s light years ahead of everyone else's on the planet.2. Murdoch Pulls out of GoogleThe biggest, most powerful, and once-thought-to-be indestructible print media outlets have arrived at their moment of reckoning. For a decade, the likes of the Los Angeles Times, The Washington Post, and The New York Times (not to mention innumerable other oudets), have offered up their best work on a silver, online platter-- for free. Look at where it got them. The first is in jeopardy of closing up shop, the Post has shuttered its domestic bureaus, and the Gray Ladys just eliminated some 100 newsroom jobs, the second such move in two years. Enter Rupert Murdoch, theoutspoken Aussie head of News Corp whose empire spans from the Times of London to the most august business publication in the United States, The Wall Street Journal. For months now, he has been ranting about the free consumption of news online. His radical idea? Murdoch wants to stop Google from indexing his sites, and he wants Microsoft to pay for the privilege instead. In other words, he wants someone to pay for the stuff his journalists produce.A chorus of bloggers is crying that the old man's thinking cuts against the force of history--namely, that information wants to be free, and that any future-minded company ignores that fact at its peril. Techdirt says the news baron is a hypocrite. Boing Boing says Murdoch's threat to block searches and shroud his sites with paywalls is nothing more than a bluff. Think again. This isn't a doddering old coot who doesn't get the Web. Murdoch is a savvy business-man who just might lead an industry back into the reality-based community. With billions in cash on hand, he can afford short-term losses as his properties experiment with strategies that do not involve the essential untenability of giving the product away. And once he proves that a news publication can poke Google in the eye and survive, others will follow suit. After all, if they don't, Murdoch may be the only one left standing.3. Malw Disrupts FacebookWhen it comes to malware, the law of gravity is this: the bad guys go where the money is. That's why threats to computer users have evolved from viruses to botnets and phishing attacks--each iteration is more likely to produce profit. How does a piece of malware make money, exactly? In a number of ways, from rifling through your files for bank-account information and credit-card numbers, to turning your computer into a spam factory. The follow-the-money rule also helps explain why there aren't many threats for *Mac computers. They may have some security advantages over PCs, but mostly their market share isn't big enough to be worth malware creatorg time. )It follows that as we conduct more of our lives online, malefactors will follow us there. And where is the biggest action on the Web today? Facebook, which just signed up its 350 millionth user and shows no sign of slowing down. Facebook has seen malware before; the latest threat is an especially virulent edition of the "Koobface" worm that has bedeviled the social network for months. It's going to get worse from here. Facebook has a team of smart engineers dedicated to keeping malicious activity off the site, but with the network ballooning in size, they'll need to redouble their defenses in even greater proportion.4. Starbucks Will Stalk YouPrivacy is so passe. We've become addicted to broadcasting our lives to the world, and the mobile phone is our greatest enabler. That's especially true now that GPS is a standard feature. And today's hottest startups are racing to become the ankle bracelet of choice, doing everything they can to track our every move and indulge our shout-it-from-the-rooftops exhibitionism. Location-aware services like Foursquare, which awards points every time you check into a bar or restaurant, have become staples among the early-adopter crowd. Meanwhile, Twitter6 has added geolocation to its service, meaning each tweet is like a thumbtack on the map of your daily travels. Rumors have it that Facebook, with its 350 million users, is heading in the same direction. It's only a matter of time before advertisers follow. You can almost hear the screams of joy coming from marketing departments nationwide: soon companies will be able to target their ad campaigns based not just on who you are, but where you are. Passing by a Starbucks? Your phone just offered you 10 percent off a peppermint latte!5. Movie Downloads Stall Blu-rayBlu-ray may have won the war with its rival, HD-DVD---but does anyone care? While consumers were waiting for the two formats to duke it out--nobody wanted to plunk down several hundred bucks on a losing technology--they discovered that downloading movies to their homes has matured into a great way to watch their favorite titles. A Harris Interactive poll in June found that only 7 percent of consumers without Blu-ray players planned on buying one in the next year. Whafs holding back a format that everyone agrees is showstoppingly gorgeous to watch? Money is a big part of it, of course. Getting video over the Internet through iTunes9 or Amazon Video on Demand can be much cheaper than purchasing physical copies. Sometimes the value is truly insane: all it costs to binge out on seasons one, two, and three of Friday Night Lights is $ 8.99. That's the price of the cheapest monthly subscription to Netflix, which allows unlimited streaming of some shows and movies to your PC, or to your big screen if you own an Xbox 360, PlayStation 3, newer TiVo, or a similar device,Yes, a Blu-ray disk provides better quality picture and sound. But as Wired magazine argued in a recent cover story, consumers are enjoying a "Good Enough Revolution" : we're nuts about MP3s, even if they sound kind of crappy, and we can't watch enough YouTube clips, even though they're pixellated and choppy. The feverish pursuit of top quality is no longer our only concern. Sometimes convenience matters more.6. Your Phone Replaces Your WalletDuring its most recent pledge drive, the popular public-radio program This American Life followed a familiar script, exhorting its users to chip in $10, $ 5, even just $1, to help pay for its weekly broadcast. The pitch wasn't new, but one of the payment methods was instead of heading to your computer and entering your credit-card information, you could simply send $ 5 to the show via text message. Long promised, never realized, mobile payments will finally take off in the U. S. in 2010. Already the sector is a beehive of activity, with companies like Zong and mPayy enabling cus tomers to pay for online purchases with only a phone number. Obopay, another mobilepayments company, received $ 35 million from Nokia in 2009, and it will have a wide rollout on that company's phones. Perhaps the best sign that the sector is poised for takeoff is that Twitter creator and tech superstar Jack Dorsey has set his sights on it. His new company, Square, launched in December, allows merchants to accept credit-card payments with cell phones. True, Square doesn't untether us from plastic just yet, but it's only a matter of time before "Cash or credit?" becomes "Cash or cell?"7. Facebook Goes PublicAt only 25 years old, Facebook's Mark Zuckerberg has turned his donn-room idea into a global empire. Might he identify with Alexander the Great, who wept at the size of his dominion because there were no more lands left to conquer? Not just yet: he can still take the company public. In November, the social-networking company took a major step toward that event by announcing that it was creating two classes of stock: one class suitable for sale in an initial public offering, and one that is vested with 10 times the voting power. An IPO under those conditions would flood the company with cash while keeping control firmly in Zuckerbergs hands. If that sounds familiar, it's because the strategy is the same one used by Google before it went public in 2004. Zuckerberg is as cutthroat and super-ambitious as he is socially awkward that is to say, very--and he would stand to become an actual billionaire, not just a virtual one. His Personal wealth has yo-yo'd in line with various private valuations of his company over the years. Facebook also announced this year that it is cash-flow positive, and a successful IPO would cement the site as a viable business, while archrival Twitter stillscrambles for a business model.8. Twitter Use FlatlinesTwitter is almost synonymous with explosive growth. But there are signs that 2009's darling of the Internet has already begun to level off, a reversal that would have seemed impossible not long ago. In February 2oo9, Nielsen Online reported that Twitter's 7 million unique visitors constituted more than 1,000 percent growth in just a year's time. Ashton Kutcher, after beating CNN to the million-follower mark in a neckand-neck race, began blasting past later milestones with ease. (He's now at 4.1 million followers. ) And when Oprah Winfrey embraced the service in April, Twitter's popularity simply hockey-sticked.There were skeptics all along-- Nielsen also reported last spring that 60 percent of Twitter users failed to return after one month but excitement about the new mediurm's potential made them easy to dismiss. Now the data have become difficult to ignore. Twitters U. S. traffic actually declined from September to October, according to a range of measures. We're by no means Twitter haters--here's proof--but it seems clear that the service is in for a period of modest performance, as sign-ups of new users are measured against better estimates of existing users who neglect their accounts. One of the things that has made Twitter so successful is its wide-open API; ironically, that same transparency can provide a reality check on the number of people who have let their accounts go totally dormant who began tweeting during the Oprah bubble, but turned out to be making just a short stop at the birdbath.9. Microsoft Pushes Out Steve BallmerBallmer's 10th anniversary as CEO of Mierosoft arrives in January, but ifs hard to imagine he'll be celebrating. Mierosoft stock has dropped by nearly 50 percent on his watch, lagging not just other teeh eompanies but even the Dow Jones industrial average. Distracted by the Windows Vista fiasco, Ballmer has missed every big new tech market of the past decade. Google won the race for Internet search and keyword advertising. Apple won in MP3 players and online music sales, and now holds the high ground in mobile phones, while Windows Mobile fades away. Microsoft's Zune music player is a dud. Bing, Microsoft's search engine, will never catch Google. Ballmer is said to be a brilliant guy, but he got a black eye for the way he blundered and blustered and finally botched an attempted acquisition of Yahoo. He's a screamer and a bit of a bully--not the easiest guy to work for. If Microsoft were any other company, this guy would be in trouble. But the catch is, Ballmer was put into the job by Microsoft founder Bill Gates, and the two have been pals since their undergraduate days at Harvard. If Gates wants to get rid of Ballmer, he' 11 have to craft some kind of graceful exit that lets his buddy save face. Another problem: there's no heir apparent on the management team. Nevertheless, investors must be getting restless. Soon they'll start calling for a shake-up.10. Google Faces Antitrust SuitThe Feds are already looking at Google on a variety of fronts. Its deal with book publishers has drawn scrutiny. In 2009 it was hassled by the Federal Trade Commission over possible anticompetitive connections because it shared two board members with Apple, a situation that got resolved when Google CEO Eric Schmidt quit Apple's board, and Arthur Levinson, an Apple board member, quit the Google board. Regulators freaked out again when Google tried to make a search partnership with Yahoo. Supposedly the Feds were ready to bring charges, but then Google walked away from the deal.After facing this scrutiny in the past year, Google has launched a kind of ongoing publicity campaign, wooing the media and hoping to convince people that it isn't really a big bad company. It likes to say that it's operating in a highly competitive field and that its users can leave with the click of a mouse. But the fact is, Google handles two thirds of all searches in the United States. Whether that can legally be defined as a "monopoly" and whether Google can be shown to have abused its powerful market position remains to be seen. But regulators here and/or in the European Union will find Google so tempting a target that they will not be able to resist bringing a case to find out.Addicts of the Information AgeAmong everybody from our leaders to our teenagers, no habit is spreading faster than being connected 24/7 via a smart phone.[2] Its penetration in the U.S. is estimated at 18%, and it seems that everywhere you turn, people are using their smart phones in new ways and in new places. Samsung recently estimated that it expects 500 million global smart-phone users by 2012. Actual phone calls are becoming extinct compared with handheld texts and email messages--whoever thought people would prefer typing to talking? But the evidence appears to say they do.[3"] This has also given rise to a group of people--the top 10% of smart-phone users--who just can't stop. They are the smartphoniacsI, the true addicts of the information age.[4] Here are five tell-tale2 traits of Smartphoniacs :Do they take their smart phones with them when they get up from the table to go to the restroom---and do they take an awful lot of trips there?Do you receive messages from them while you know they are driving (increasingly being harmed in state after state), or at midnight on Saturday night?Do they come up with excuses in the middle of a conversation to pull out their smart phone--something like "let me jot something you said down so I don't forget it", and then sneak a look at all their messages?Are they suffering from sprained or elongated thumbs?Do they openly use their smart phones in inappropriate places, such as first dates, at Rosh Hashanah4 or Christmas dinner, in hospital delivery rooms, or on job interviews?[5 ] If your "friend" fits four out of five of these, then he or she is a smartphoniac. If he fits only two or three of them, he is just another typical user who stays connected on the street, in meetings and at the movies.[6] As these devices pop up everywhere, there has been a recent spate of articles about smart-phone "manners"--as if using your phone when your boss, or your mother, is talking to you is just a matter of poor training on their part. I don't think your boss or your mom ever said "go ahead, text while I'm talking to you". So it's just not a matter of manners. Ifs much more the result of a deeper disconnect anxiety, an irrepressible fear that you will miss something if you put it away.[7] I once worked with a candidate for Senate who emailed me from the podiums during a debate. Many 'CEOs communicate today primarily from their smart phones. Hillary Clinton and Barack Obama used them on the campaign trail, while John MeCain didn't.[8] The famed red phone to call the Russian premier in the event of a national security emergency could now be replaced by a red smart phone. Imagine if the world's top leaders were all connected bysmart phones and they communicated directly and frequently about issues of mutual concern. It would revolutionize diplomacy.[9] But Smartphoniacs are an eclectic mix of the successful and powerful, busy professionals, teenagers and college students. All of them commtmicate incessantly.[10] In Korea, more than three in 10 youths who carry mobile phones are said to be addicted. In Germany, there are an estimated 380,000 texting addicts—folks who withdraw from the very family and friends their machines were supposed to connect them to. While there hasn't been a formal study of Smartphoniacs in America, we know that between the second quarter of 2007 and the second quarter of 2008, the North American smart-phone market grew 78.7%. About 139.3 million smart phones were sold world-wide last year, and half of U. S. smart-phone users report using their devices more today than they did just three months ago.[11] Last month, the National Texting Championship award and its $ 50,000 grand prize went to a 15-year-old who texts 500 times a day. A recent poll found that 42% of teens can text with their eyes closed. And based on other studies on the intensity of smart-phone use, we can guess that Smartphoniacs skew male, affluent and well-educated. Not since the television has any invention changed the lifestyle habits of Americans more than the smart phone. The recent movie Seven Pounds detailed the guilt of an executive who caused a fatal car crash because he emailed while driving.[12] To be sure, there are forces calling for temperance7. Some people refuse to date people who use smart phones. Many parents just say no. Legislators are getting into the act to protect public safety. But for the most part, Americans of every age and stage are wrapping themselves in apps, chcks and instantaneous communication as part of a social network. And some small but significant percentage of this group is going to take a one-way slide to the bottom, where the compulsion to use their smart phones is so strong that they can only hope their batteries last long enough to text a cry for help.[13] We're not far away from Smartphoniacs Anonymous or Mothers Against Smart Phones. We've been through this with TV, the Intemet and videogames. In the end it all works out and we successfully integrate them into our lives, even though we are never again the same. At least with smart phones, with all their usage counters, we will be able to tell who has recovered from the binges.。

科技英语原文及简单翻译How ASIMO WorksIntroduction to How ASIMO WorksWant a robot to cook your dinner, do your homework, clean your house, or get your groceries? Robots already do a lot of the jobs that we humans don't want to do, can't do, or simply can't do as well as our robotic counterparts.Honda engineers have been busy creating the ASIMO robot for more than 20 years. In this article, we'll find out what makes ASIMO the most advanced humanoid robot to date.The Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the first humanoid robot in the world that can walk independently and climb stairs.Rather than building a robot that would be another toy, Honda wanted to create a robot that would be a helper for people -- a robot to help around the house, help the elderly, or help someone confined to a wheelchair or bed. ASIMO is 4 feet 3 inches (1.3 meters) high, This allows ASIMO to do the jobs it was created to do without being too big and menacing.ASIMO's Motion: Walk Like a HumanHonda researchers began by studying the legs of insects, mammals, and the motion of a mountain climber with prosthetic legs to better understand the physiology and all of the things that take place when we walk -- particularly in the joints. For example, the fact that we shift our weight using our bodies and especially our arms inorder to balance was very important in getting ASIMO's walking mechanism right. The fact that we have toes that help with our balance was also taken intoconsideration: ASIMO actually has soft projections on its feet that play a similar role to the one our toes play when we walk. This soft material also absorbs impact on the joints, just as our soft tissues do when we walk.ASIMO has hip, knee, and foot joints. Robots have joints that researchers refer to as \degrees of freedom.\A single degree of freedom allows movement either right and left or up and down. ASIMO has 34 degrees of freedom spread over different points of its body in order to allow it to move freely. There are three degrees of freedom in ASIMO's neck, seven on each arm and six on each leg. The number of degrees offreedom necessary for ASIMO's legs was decided by measuring human joint movement while walking on flat ground, climbing stairs and running.ASIMO also has a speed sensor and a gyroscope sensor mounted on its body. They perform the tasks of:? ?sensing the position of ASIMO's body and the speed at which it is moving relaying adjustments for balance to the central computer These sensors work similarly to our inner ears in the way they maintain balance and orientation.ASIMO also has floor surface sensors in its feet and six ultrasonic sensors in its midsection. These sensors enhance ASIMO's ability to interact with its environment by detecting objects around ASIMO and comparing gathered information with maps of the area stored in ASIMO's memory.To accomplish the job our muscles and skin do in sensing muscle power, pressure and joint angles, ASIMO has both joint-angle sensors and a six-axis force sensor.Unless you know a lot about robotics, you may not fully grasp the incredible milestone it is that ASIMO walks as we do. The most significant part of ASIMO's walk is the turning capabilities. Rather than having to stop and shuffle, stop and shuffle, and stop and shuffle into a new direction, ASIMO leans and smoothly turns just like a human. ASIMO can also self-adjust its steps in case it stumbles, is pushed, or otherwise encounters something that alters normal walking.In order to accomplish this, ASIMO's engineers had to find a way to work with the inertial forces created when walking. For example, the earth's gravity creates a force, as does the speed at which you walk. Those two forces are called the \inertial force.\ground, called the \posture has to work to make it happen. This is called the \zero moment point\(ZMP). To control ASIMO's posture, engineers worked on three areas of control:? ?Floor reaction control means that the soles of the feet absorb floor unevenness while still maintaining a firm stance.Target ZMP control means that when ASIMO can't stand firmly and its body begins to fall forward, it maintains position by moving its upper body in the direction opposite the impending fall. At the same time, it speeds up its walking to quickly counterbalance the fall.?Foot-planting location control kicks in when the target ZMP control has been activated. It adjusts the length of the step to regain the right relationship between the position and speed of the body and the length of the step.ASIMO's Motion: Smooth MovesASIMO can sense falling movements and react to them quickly; but ASIMO's engineers wanted more. They wanted the robot to have a smooth gait as well as do something that other robots can't do -- turn without stopping.When we walk around corners, we shift our center of gravity into the turn. ASIMO uses a technology called \predictive movement control,\Intelligent Real-Time Flexible Walking Technology or I-Walk, to accomplish that same thing. ASIMO predicts how much it should shift its center of gravity to the inside of the turn and how long that shift should be maintained. Because this technolgy works in real time, ASIMO can do this without stopping between steps, which other robots must do.Essentially, with every step ASIMO takes, it has to determine its inertia and then predict how its weight needs to be shifted for the next step in order to walk and turn smoothly. It adjusts any of the following factors in order to maintain the right position:? ? ? ?the length of its steps its body position its speedthe direction in which it is steppingWhile reproducing a human-like walk is an amazing achievement, ASIMO can now run at speeds up to 3.7 miles per hour (6 kilometers per hour). In order to qualify as a true running robot, ASIMO must have both feet off the ground for an instant in each step. ASIMO manages to be airborne for .08 seconds with each step while running. Honda engineers encountered an entirely new set of challenges while trying to give ASIMO the ability to run. They gave ASIMO’s torso a degree of freedom to aid in bending and twisting so that the robot could adjust its posture while airborne. Without this ability, ASIMOwould lose control while airborne, possibly spinning in the air or tripping when landing.In order to make turns smoothly while running, the engineers enhanced ASIMO's ability to tilt its center of gravity inside turns to maintain balance and counteractcentrifugal force. ASIMO could even anticipate turns and begin to lean into them before starting the turn, much like you would if you were skiing or skating.ASIMO如何工作介绍如何工作。
