科技英语presentation

关于推荐科技产品的英语作文对话John: Hey Sarah, what are you doing on your tablet?Sarah: Oh hi John! I'm just browsing some tech websites looking at the latest gadgets and gizmos. You know how much I love technology!John: Yeah, you're always checking out the newest phones, computers, and other cool tech stuff. Have you seen anything good lately that you'd recommend?Sarah: Definitely! There are a few products I'm really excited about. First up, have you heard about the new SuperPhone X2? It's supposed to be amazing!John: No, what's so great about it?Sarah: Well, it has this crazy high-definition camera that can take pictures with like a billion pixels or something. The display is also supposed to be incredible - brighter and sharper than anything else out there. And get this - it's waterproof up to 100 feet underwater!John: Whoa, that does sound awesome! But I'll bet it costs a fortune.Sarah: You got that right. The base model is around 1200! Maybe we can ask for it as a Christmas/birthday present for the next few years.John: Haha, good luck with that! What else have you got your eye on?Sarah: Okay, how about this - the GameVision 5000 virtual reality headset and game system. It's supposed to give you the most realistic VR experience ever for gaming, watching movies, you name it.John: Virtual reality? Like we're actually inside the game? That's so cool!Sarah: Exactly! The graphics and motion tracking are insane. You can look around in any direction and it feels like you're really there. It even lets multiple people join the same virtual world together.John: Now you're just making me jealous. I'll never be able to afford that! Don't they cost like 500 at least?Sarah: Well, yeah...the full system is pretty pricey. But maybe we could start with just the headset for around 300? Then we can take turns using it.John: I guess that's not too unreasonable. What other tech have you been looking at?Sarah: One more thing I'm really interested in is this new laptop/tablet hybrid called the FlexBook Pro. It's a full Windows laptop when you need it, but the screen detaches from the keyboard so you can use it as a tablet too.John: That's pretty handy! A lot of my friends just have iPads for taking notes and doing homework, but a hybrid device could replace both a laptop and a tablet.Sarah: Exactly! And this particular model is supposed to have an amazing battery life, a lightning-fast processor, and it works with a stylus for writing and drawing right on the screen.John: Okay, now I really want one of those FlexBook Pro things! How much do they cost?Sarah: Well, the base models start around 800, but they can get pretty expensive if you add more storage, better processors, etc. Maybe we could split the cost if we both chip in our allowance money?John: That's not a bad idea! Let me talk to my parents about it. You've definitely got me interested in some of these new tech products.Sarah: I know, isn't it all so cool? Technology keeps getting better and better every year. I can't wait to see what kinds of awesome products they come up with next!John: Me neither! Although at this rate, I'll need to get a job and start saving up seriously if I want to be able to afford it all.Sarah: Haha, you're probably right about that. But just think how mind-blowing the tech world will be in like 10 or 20 years! I can't even imagine what they'll come up with.John: You've got me really excited now! I'll start doing extra chores around the house to earn more money. Maybe my parents will even chip in if I get good grades.Sarah: There you go! In the meantime, we can keep researching the latest products and adding them to our wish lists. Who knows, maybe we'll get lucky!John: You've got that right. Thanks for filling me in on some of the hot new tech items, Sarah. I'm definitely feeling motivated to save up for some amazing gadgets!Sarah: Anytime, John! I'm always happy to share my tech knowledge. Maybe we can start a tech club at school too to really geek out.John: A tech club? Now there's an idea! Although we might have to limit you on how much you can talk about products...otherwise we'll be there all day!Sarah: Haha, you know me too well! Okay, I'll try to contain my tech enthusiasm. But only a little bit!。

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。

科技产品的作文英文Title: The Impact of Technological Products on Our Lives。

In today's rapidly advancing world, technological products have become an integral part of our daily lives, revolutionizing the way we communicate, work, and entertain ourselves. From smartphones to smart homes, from social media platforms to virtual reality headsets, these products have significantly influenced various aspects of human existence. In this essay, we will explore the profound impact of technological products on our lives.First and foremost, technological products have transformed communication. With the advent of smartphones and social media platforms, communication has become instantaneous and global. People can connect with friends, family, and colleagues across the globe within seconds, breaking down geographical barriers. This has facilitated the exchange of ideas, cultures, and experiences like neverbefore, fostering a more interconnected world.Moreover, technological products have revolutionized the way we work. The rise of remote work tools, such as video conferencing software and cloud-based collaboration platforms, has enabled people to work from anywhere with an internet connection. This flexibility has not only increased productivity but also improved work-life balance, allowing individuals to better manage their personal and professional lives.Furthermore, technological products have transformed entertainment. Streaming services, gaming consoles, and virtual reality experiences have provided people with a myriad of entertainment options at their fingertips. Whether it's watching the latest blockbuster movie, playing immersive video games, or exploring virtual worlds, technological products have redefined the way we entertain ourselves, offering endless possibilities for escapism and enjoyment.However, along with their numerous benefits,technological products also pose certain challenges and risks. One of the most significant concerns is privacy and security. With the proliferation of personal data being collected and shared online, individuals are increasingly vulnerable to privacy breaches and identity theft. Moreover, the constant connectivity afforded by technologicalproducts has led to issues such as digital addiction and cyberbullying, raising questions about their long-term effects on mental health and social relationships.In addition, the rapid pace of technological innovation has led to concerns about job displacement and economic inequality. As automation and artificial intelligence continue to advance, certain jobs may become obsolete, leading to unemployment and economic disruption. Furthermore, access to technological products is not evenly distributed, with marginalized communities often being left behind, widening the digital divide and exacerbatingexisting inequalities.Despite these challenges, technological products have the potential to drive positive change and innovation insociety. From healthcare advancements to environmental sustainability solutions, technology has the power to address some of the most pressing challenges facing humanity. By harnessing the transformative potential of technological products responsibly and ethically, we can create a future where technology serves as a force for good, enhancing the quality of life for all.In conclusion, technological products have had a profound impact on our lives, revolutionizing communication, work, and entertainment. While they offer numerous benefits and opportunities, they also pose challenges and risks that must be addressed. By recognizing the potential of technological products to drive positive change and addressing their associated challenges, we can harness the full potential of technology to create a better, more equitable future for all.。

科技英语特点范文例文The field of science and technology has its own unique language and style of communication. Technical English, also known as scientific English, is the specific form of the English language used in academic and professional settings related to science, engineering, and technology. It is characterized by a distinct vocabulary, grammatical structures, and writing conventions that set it apart from general or everyday English. Understanding the characteristics of technical English is crucial for effective communication and understanding in the scientific and technological domains.One of the primary features of technical English is its specialized vocabulary. The language is filled with technical terms, acronyms, and jargon that are specific to particular fields or disciplines. These specialized terms are often derived from Greek or Latin roots, reflecting the historical influence of classical languages on the development of scientific terminology. For example, terms like "photosynthesis," "electromagnetism," and "cybernetics" are commonly used in technical contexts but may be unfamiliar to those outside the relevant fields. The use of these specialized terms servesto convey precise and unambiguous information, which is essential in scientific and technological communication.In addition to the specialized vocabulary, technical English is also characterized by the use of precise and concise language. Scientific and technological writing often aims to present information in a clear, logical, and objective manner, avoiding unnecessary embellishments or subjective expressions. Sentences tend to be short and straightforward, with a focus on conveying information efficiently. The writing style is typically formal and impersonal, eschewing the use of personal pronouns or colloquial expressions. This emphasis on clarity and precision helps to ensure that the information being communicated is accurately understood by the target audience.Another distinctive feature of technical English is the extensive use of passive voice constructions. Passive voice is commonly employed in scientific and technological writing to shift the focus from the agent or doer of an action to the object or result of that action. For example, instead of saying "The researcher conducted the experiment," a technical writer might say, "The experiment was conducted." This passive construction places the emphasis on the experiment itself rather than the individual performing the action. The use of passive voice helps to maintain an objective and impersonal tone, which is often preferred in scientific and technicalcontexts.Technical English also relies heavily on the use of visual aids and graphical elements to supplement the written text. Figures, tables, diagrams, and illustrations are frequently incorporated into technical documents to help convey complex information, visualize data, or provide additional context. These visual elements are often accompanied by detailed captions or explanations that further clarify the information being presented. The integration of visual aids is a crucial aspect of technical communication, as it can enhance the reader's understanding and facilitate the effective communication of technical concepts.Grammatical structures in technical English also exhibit some unique characteristics. For instance, the language often features the extensive use of modal verbs (e.g., "can," "should," "must") to express degrees of possibility, necessity, or obligation. Additionally, technical writing frequently employs the use of conditionals (e.g., "if-then" statements) to describe hypothetical scenarios or causal relationships. The language also tends to favor the use of the present tense, even when describing past or future events, as this helps to maintain a sense of objectivity and timelessness in the presentation of technical information.Furthermore, technical English is characterized by the consistent useof formal and standardized formatting conventions. Technical documents, such as research papers, reports, or manuals, often adhere to specific guidelines regarding the structure, organization, and presentation of information. These guidelines may include the use of headings, subheadings, section numbering, and consistent citation styles (e.g., APA, MLA, IEEE). Adherence to these formatting conventions helps to ensure that technical information is presented in a coherent and easily navigable manner, facilitating the reader's understanding and the overall effectiveness of the communication.It is important to note that the characteristics of technical English can vary depending on the specific field or discipline, as well as the intended audience and purpose of the communication. For instance, the language used in engineering reports may differ slightly from that used in medical research papers or computer science documentation. However, the core features of specialized vocabulary, precise and concise language, passive voice constructions, visual aids, and standardized formatting conventions are generally shared across the diverse domains of science and technology.In conclusion, technical English is a distinct form of the English language that is characterized by a specialized vocabulary, precise and concise language, the use of passive voice constructions, the integration of visual aids, and the adherence to formal grammatical structures and formatting conventions. These characteristics serve tofacilitate clear, unambiguous, and effective communication within the scientific and technological realms, enabling the efficient exchange of complex information and the advancement of knowledge in these vital fields.。
