英语课presentation的用法
英语课presentation的用法示例文章篇一：《英语课presentation的用法》嗨，大家好！今天我想和大家聊聊英语课上的presentation呢。
你知道吗？在英语课里，presentation就像是一场小小的表演秀。
想象一下，你就是舞台上的小明星，要把自己知道的东西展示给大家看。
比如说，你要介绍你最喜欢的动物，那这个时候，你的presentation就是把关于这个动物的所有有趣的事儿都告诉同学们。
我记得有一次，我的同桌小明要做一个关于大熊猫的presentation。
他可紧张啦，就像怀里揣了只小兔子，心扑通扑通直跳。
他站在讲台上，刚开始声音还有点小，就像蚊子嗡嗡叫。
他说：“同学们，大熊猫可好玩儿了，它们长得圆滚滚的，黑白相间的毛就像穿了一件特制的大外套。
”然后，他越说越激动，声音也越来越大。
他还拿出自己画的大熊猫图片给我们看，说：“你们看，这大熊猫的黑眼圈，就像戴了一副大墨镜，酷不酷？”我们都被他逗笑了，也对大熊猫有了更深的了解。
这就是presentation的魔力呀，能让大家通过你的讲述，看到一个全新的世界。
那在做presentation的时候，内容是很关键的。
不能只是随便说说，得有条有理。
就像盖房子，得先有个好的框架。
比如说，你要介绍一个地方，你可以先从这个地方的地理位置说起，就像告诉大家这个房子建在哪里一样。
然后再说说这个地方有什么特别的景点呀，就像是房子里有什么特别的房间一样。
接着呢，可以讲讲那里的人们的生活习惯，这就像是房子里住的人有什么特别的生活方式。
要是你东说一句西说一句，同学们就会像走进了迷宫一样，晕头转向的。
那怎么才能让自己的内容更吸引人呢？这就需要一些小技巧啦。
比如说，多讲点有趣的小故事。
我有个朋友小红，她在做关于英国的presentation的时候，就讲了一个英国女王的小趣事。
她说：“你们知道吗？英国女王特别喜欢小狗。
有一次，她的小狗在皇宫里调皮捣蛋，把一个大臣都给弄懵了呢。
presentation讲稿
presentation讲稿Good morning/afternoon/evening, ladies and gentlemen.I am honored to have the opportunity to stand here today and present to you on the topic of [标题]. During the course of this presentation, I will discuss [主题一], [主题二], and [主题三]. Please feel free to ask any questions at the end.[Introduction]Firstly, let us begin by understanding the importance of [标题]. In today's fast-paced and competitive world, effective communication and presentation skills are crucial for success in both personal and professional life. A well-executed presentation can captivate an audience, deliver key messages, and leave a lasting impression. With that in mind, let us dive into the key aspects of a successful presentation.[主题一]The first aspect to consider is the structure of the presentation. A clear and logical organization is essential for conveying information effectively. A recommended structure includes an introduction, body, and conclusion. In the introduction, provide a brief overview of the topic and grab the audience's attention. The body should consist of main points supported by evidence or examples. Use visuals, such as graphs or charts, to enhance understanding. Lastly, the conclusion should summarize the key points and leave the audience with a strong takeaway message.[主题二]Moving on to the next aspect, delivery plays a critical role in a presentation. The way you speak, move, and engage with the audience can greatly impact their level of interest and comprehension. Maintain a confident and professional demeanor. Speak clearly and audibly, ensuring everyone can hear you. Use gestures and facial expressions to emphasize key points. Additionally, maintain eye contact with the audience to establish a connection and hold their attention. Remember, effective delivery can significantly enhance the impact of your presentation.[主题三]The final aspect I would like to address is visual aids. Utilizing visuals can greatly enhance the audience's understanding and retention of information. However, it is crucial to use them appropriately. Keep visuals simple, relevant, and visually appealing. Avoid overcrowding slides with excessive text or complex graphics. Instead, use bullet points or concise phrases to highlight key information. Remember, visuals are meant to complement your presentation, not replace it. Therefore, ensure your words and visuals work together harmoniously.[Conclusion]In conclusion, an outstanding presentation requires careful planning and execution. By structuring your presentation effectively, delivering it with confidence and clarity, and utilizing appropriate visuals, you can engage and inform your audience successfully. Always remember to practice beforehand, tailor your message to the specific audience, and remain adaptable to their needs. With these skills, you will be well on your way to becoming an exceptional presenter.Thank you for your attention. I am now open to any questions you may have.。

presentation开场白
presentation开场白presentation开场白presentation开场白（一）Morning everyone! Today we’ll have a talk about dream and success in America.Everybody has his or her own dream and standard of being a successful man, but they are not actually the same because of different background and life experience and sex.There we have made an investigation about the topic. Let’s have a look at the video.（Video）OK! It looks as though different people have different opinion about being a successful man, and maybe they are always dreaming of achieving success at an early age.The American Dream is a book about American dream written by a famous journalist Dan Rather, published in 2002. He provided many stories of ordinary men and women accomplishing the extraordinary.You know America is an integrated country with a history only more than 200 years. After the continent was discovered by Europe, people all over the world came here to search for their own dream. American culture lay emphasize on individuals' value: self first, personal need first. So pursue of individual benefit and enjoyment, emphasize on achieving individual value by self-strive and self-design was highly respected. That is to say they usually have an ambition or desire to gain something they need. If they gain this, they would consider him as a successful man. Maybe that’s just what we call “American dream”。
Presentation演讲实例
Early visions of wireless power actually were thought of by Nikola Tesla basically about 100 years ago. And so, in fact, he actually set about doing a variety of things. Built the Tesla coil. This tower was built on Long Island back at the beginning of the 1900s. And the idea was, it was supposed to be able to transfer power anywhere on Earth. We'll never know if this stuff worked. Actually, I think the Federal Bureau of Investigation took it down for security purposes, sometime in the early 1900s.Bad news？Creative ideas that this tesla coil becomes the staples of soviet military installation.The electricity out can devastate the enemy infantry and proved almost as effective on most vehicles.Let’s back to the theme.The one thing that did come out of electricity is that we love this thingso much.I mean,think about how much we love it.If you just walk outside,there are infinite dollars have been invested in infrastructure around the world, putting up wires to get power from where it's created to where it's used. The other thing is, we love batteries.However,for those of us that has environmental pollution to our world,there is something like 40 billion disposable batteries built every year for power that. Do you ever wonder what happens to this stuff? 40 billion of these things built. This is what happens. They fall apart, they disintegrate, and they end up here.Without a battery,we need a wire for electricit though.Whereas,bad experience would still be thereWe've all dealt with wire jungles behind our computers and televisions. They just crop up, a natural tangle of cords formed by the devices we connect to each other. It's just a reality of modern technology. However, they can be more than simply inconvenient; large cable tangles can be detrimental to certain electronics' performance, and in extreme cases can be outright dangerous.Besides the risk of fire and electrical short, a tangle of power cables can potentially damage your electronics through unwanted power loss (that is, unexpectedly yanking a power cable out of the wall).There is another problem with interference.Analog signals sent over cables, like audio piped out from an receiver to speakers, can get interference from strong electrical currents, like power cables. An audible buzz can be heard when placing speaker cables (or any other analog audio cable) within a few inches of a live power cable.So ,think about it.Waking up at night to the third night in a row that his wife's cellphone was beeping because it was running out of battery power. And he was thinking, "With all the electricity that's out there in the walls, why couldn't some of that just come into the phone so I could get some sleep?"He is Dr.Soljacic,the theretical physicist at MIT,coming up with the concept of tranferring the electricity over distance.Basically they were able to light a 60 watt light bulb at a distance of about two meters. It got about 50 percent of the efficiency -- by the way, that's still a couple thousand times more efficient than a battery would be, to do the same thing. This was actually the experiment. So you can see the coils were somewhat larger. The light bulb was a fairly simple task.But he were able to light that, and do it very successfully.So how does it work?Imagine a coil. For those of you that are engineers, there's a capacitor attached to it too. And if you can cause that coil to resonate, what will happen is it will pulse at alternating current frequencies -- at a fairly high frequency, by the way. And if you can bring another device close enough to the source, that will only work at exactly that frequency, you can actually get them to do what's called strongly couple, and transfer magnetic energy between them. And then what you do is, you start out with electricity, turn it into magnetic field, take that magnetic field, turn it back into electricity, and then you can use it.Okay,you may have the question that is this system be able to exchange the different power between different objects.Let’s move on to the evidence for that.The amount of wine in the glass affected its resonant frequency by singer’s voice performing in a room filled with wine glasses.Only when absorbed enough energy from sound waves in the air it was to be shattered –while the other glasses remained unharmed.In this example, energy is transferred very efficiently between sound waves in the air and the mechanical vibrations of the glass, at the partially filled wine glass’resonant frequency.。

英语presentation范文Good morning everyone,Today I would like to talk to you about the topic of climate change and its impact on our environment. As we all know, climate change is becoming an increasingly urgent issue that needs to be addressed.First, let's define climate change. It refers to long-term changes in temperature, precipitation, wind patterns, and other aspects of the Earth's climate system. These changes are primarily caused by human activities such as the burning of fossil fuels, deforestation, and industrialization. The effects of climate change are wide-ranging and have a significant impact on the environment, ecosystems, and human health.One of the most noticeable effects of climate change is the rise in global temperatures. Over the past century, the average global temperature has increased by about 1 degree Celsius. This may not sound like much, but it has drastic consequences. Rising temperatures lead to the melting of polar ice caps, resulting in rising sea levels and increased flooding in coastal areas. This threatens the homes and livelihoods of millions of people around the world.Furthermore, climate change is causing more extreme weather events such as hurricanes, droughts, and heatwaves. These events can have devastating consequences. For example, the recent hurricanes in the Caribbean and the wildfires in California are directly linked to climate change. These events not only causeimmediate damage and loss of life but also have long-lasting effects on the affected regions.In addition to these direct impacts, climate change also poses indirect threats to our environment and ecosystems. For example, rising temperatures and changes in rainfall patterns can lead to the loss of biodiversity and the extinction of plant and animal species. This loss of biodiversity has far-reaching consequences as it disrupts the delicate balance of ecosystems and reduces the resilience of our planet to other threats such as disease and pollution.So, what can we do to address climate change? There are several actions that can be taken at various levels, from individual to global. Firstly, we can all make small changes in our daily lives to reduce our carbon footprint. This includes using public transport or cycling instead of driving, reducing energy consumption at home, and recycling as much as possible. Secondly, governments and international organizations need to implement policies and regulations that promote renewable energy and reduce greenhouse gas emissions. Finally, we need to raise awareness and educate the public about the importance of climate change and its impacts. This includes spreading information through public campaigns, schools, and the media.In conclusion, climate change is a pressing issue that requires immediate attention. The effects of climate change are already being felt around the world, and if we do not take action, the situation will only worsen. It is up to all of us to make a difference and work towards a sustainable future.Thank you for listening.。

英语presentation三分钟范文
英语presentation三分钟范文篇1Dear friends, today I want to share with you one of my favorite books, "The Little Prince". This is not just an ordinary book, but a magical journey that has deeply touched my heart!The story is full of wonders and wisdom. The little prince leaves his own planet and travels through various asteroids, meeting all kinds of strange and interesting characters. How fascinating it is! Isn't it amazing to think about his adventures?One of the most unforgettable plots is when the little prince meets the fox and they have a profound conversation about taming. This part really made me think a lot. It made me understand the meaning of connection and responsibility.This book has had a huge impact on me. It taught me to look at the world with a childlike innocence and to cherish the simple and true things in life. Don't we all need such reminders in this busy and complicated world?So, my dear friends, I highly recommend "The Little Prince" to you. Let's all embark on this wonderful journey of the heart together!篇2Oh my goodness! Let me share with you an unforgettable journey that changed my life.It was a sunny summer, and I decided to embark on a solo trip to a remote village. The moment I arrived, I was stunned by the breathtaking scenery. The mountains were like giants standing tall, covered with lush greenery. The clear blue sky seemed to touch the tips of the mountains. The rivers flowed gently, making a soothing sound as if singing a lullaby.The local food was simply divine! I tasted the most delicious homemade pies and fresh fruits. The flavors exploded in my mouth, leaving me craving for more. But what made this trip truly remarkable were the people I met. There was an old man who shared his life stories with me, and his wisdom and kindness touched my heart deeply.This journey wasn't just about the beautiful views and mouthwatering food. It was a journey of self-discovery and growth. I overcame my fear of being alone and learned to enjoy the present moment. It was an experience I will cherish forever. How wonderful life can be when we step out of our comfort zone and embrace the unknown?篇3Today, I want to talk about a really hot social phenomenon that has been changing our lives in a big way - the popularity of electronic payment! How amazing is it that we can simply take out our phones and complete a transaction in seconds? It's so convenient! No more fumbling for cash or worrying about having the right change.But wait! Have you ever thought about the potential problems it mightbring? What if there are technical glitches? What if our personal financial information gets leaked? These are serious questions that we need to consider.Now, let's turn to another important topic - environmental protection! Oh my goodness, how crucial it is for our future! We all know that our planet is facing many challenges. But what can we do as individuals? We can start by reducing our use of single-use plastics. Can you imagine the amount of plastic waste we produce every day? It's terrifying! We can also choose to use public transportation or bike instead of driving alone. Every small action counts!In conclusion, whether it's the convenience and challenges of electronic payment or the importance of our actions for the environment, we should think deeply and act wisely. Let's make a positive difference together!Thank you!篇4Today, I'm thrilled to share with you something truly remarkable! Have you ever thought about how a new technology could completely transform our lives? Well, let me introduce you to the wonders of 5G technology!5G technology is not just a simple upgrade; it's a revolutionary breakthrough! It enables incredibly fast data transmission speeds. Imaginedownloading a full-length movie in just seconds! Isn't that amazing? With 5G, smart cities will become a reality. Self-driving cars can communicate with each other in real-time, reducing traffic accidents. Remote surgeries can be performed with precision, saving countless lives!But that's not all. The future of 5G is filled with endless possibilities. It will power the Internet of Things, connecting everything from our home appliances to industrial equipment. Will our lives become more convenient and efficient? Absolutely!Now, let's shift gears and talk about a healthy lifestyle. How important is it to stay fit and eat right? Extremely important! Regular exercise not only keeps our bodies in shape but also boosts our mood and energy levels.A balanced diet, rich in fruits, vegetables, and lean proteins, gives us the nutrients we need to thrive.So, let's embrace 5G and lead a healthy life. Let's step into this exciting future together!篇5Ladies and gentlemen! Today, I want to delve into a profound philosophical issue that has perplexed humanity for ages - the relationship between free will and determinism.Have you ever wondered if our actions are truly a result of our own free choices, or are they predetermined by a series of causes and effects beyond our control? This is not just an abstract question but one that hassignificant implications for how we view ourselves and our place in the world.On one hand, the idea of free will suggests that we have the autonomy to make decisions and shape our destinies. We feel a sense of responsibility for our choices and believe that we have the power to change our lives for the better. But on the other hand, determinism argues that everything that happens is inevitable, based on prior conditions and the laws of nature. If this is the case, then are we just pawns in a cosmic game, with no real say in the outcome?This is not a simple either/or proposition. Maybe it's a complex interplay between the two. But how do we navigate this murky territory? How do we make sense of our experiences in light of this ongoing debate?The exploration of this topic is not only intellectually stimulating but also has practical relevance to our daily lives. It forces us to reflect on our actions, our motives, and the nature of moral responsibility.So, dear friends, let's keep pondering and seeking a deeper understanding of this fascinating conundrum. Thank you!。

英语3分钟presentation
英语3分钟presentationLadies and Gentlemen,Good day to you all. Today, I am thrilled to have the opportunity to share with you a topic that is very close tomy heart: "The Power of Language in Shaping Our World." Inthe next three minutes, I will be discussing the profound impact that language has on our daily lives, our cultures,and our understanding of the world around us.Firstly, let's consider the role of language in communication. Language is the primary tool we use to express our thoughts, feelings, and ideas. It is the bridge that connects us with others, allowing us to share experiences and knowledge. Without language, we would be unable to convey thecomplexities of our inner world, and the richness of human interaction would be greatly diminished.Secondly, language is a reflection of our culture. Each language carries within it the history, traditions, andvalues of the people who speak it. It is through languagethat we pass on our stories, our beliefs, and our customsfrom one generation to the next. The diversity of languages around the world is a testament to the richness of human culture and the myriad ways in which we interpret andinteract with the world.Moreover, language is a powerful tool for learning anddiscovery. It enables us to explore new ideas, to ask questions, and to seek answers. The development of language has been instrumental in the advancement of science, technology, and the arts. It is through language that we can document our findings, share our insights, and collaboratewith others to build upon the knowledge of the past.In addition, language has the power to inspire and to influence. Great speeches, literature, and poetry have the ability to move us emotionally, to challenge our perspectives, and to inspire us to action. The words we choose can uplift, motivate, or even change the course of history.However, language is not without its challenges. Language barriers can lead to misunderstandings and can hinder collaboration. The loss of languages, due to globalizationand other factors, is a significant concern, as it represents the loss of unique cultural perspectives and knowledge.In conclusion, language is a fundamental aspect of our human experience. It is through language that we connect with others, express our identities, and shape our world. As we continue to navigate the complexities of our global society,it is essential that we value and preserve the diversity of languages, and strive to bridge the gaps that languagebarriers can create.Thank you for your attention, and I look forward to any questions or discussions that may arise from this presentation.。
