用英语写作你眼中最伟大的发明作文全文共6篇示例，供读者参考篇1The Greatest Invention EverWhat is the greatest invention in the whole wide world? I've thought about this a lot, and at first, I thought it might be something like the wheel, or the light bulb, or even sliced bread! But then I realized there is one invention that is more important than all of those. The greatest invention ever is...the internet!The internet is a vast network that connects computers all over the planet. With the internet, we can access a wealth of information on pretty much any topic you can think of. Want to learn about ancient Egypt? There are websites for that. Curious about how airplanes fly? You can find videos explaining it. Need to know the capital of Tajikistan? Just a few clicks away!Before the internet, if you wanted to learn about something, you had to go to the library and hope they had a book on the subject. And if they didn't have what you needed, you were out of luck. But now, the internet gives us access to moreinformation than has ever existed in all of human history! That's incredible when you think about it.Probably the best thing about the internet is how it allows people to communicate and connect with one another. With email, texting, video chatting, and social media, we can stay in touch with friends and family members no matter how far apart we live. My cousins recently moved to Australia, but we can still share photos and videos through Facebook. It's amazing!The internet has also opened up new opportunities for learning. These days, many schools use online educational programs and games to supplement classroom lessons. And with virtual classrooms, students can even attend school over the internet if they can't physically be there. How cool is that?Speaking of school, the internet is also an incredibly useful tool for research and getting help with homework. When I'm stuck on a tough math problem or can't figure out something for my science project, I can find explanations, examples, and tutorials online. The internet is like having a private tutor available 24/7!But as awesome as the internet is, we do have to be careful about a few things. For starters, not everything you read online is necessarily true. There are a lot of websites with incorrectinformation, so you have to be sure you're getting facts from reliable sources when doing research. It's also really important to protect your privacy and personal information while on the internet, and never share details like your address or phone number online.There are also some potential downsides to the internet that we need to watch out for. Things like cyberbullying, online predators, and inappropriate content are dangers that kids and adults have to be aware of. That's why it's crucial to have parental controls and only visit kid-friendly websites. As long as we all follow basic internet safety rules, we can avoid those risks.Overall though, I truly believe the internet is the most significant invention humankind has ever created. It has revolutionized how we access knowledge, connect with others, learn new skills, and entertain ourselves. Can you imagine going back to a world without the internet? I can't!Just think about how much the internet has changed in its few decades of existence. As amazing as it is now, it's only going to keep evolving and becoming even more incredible. Virtual reality worlds, artificial intelligence assistants, enhanced online learning – who knows what mind-blowing internet technologiesare just around the corner? I can't wait to see what the future holds.In the meantime, I'll keep using the internet as my portal to enlightenment and exploring this vast universe of information and connectivity. To me, the internet isn't just the greatest invention so far – it's the key to all of the greatest inventions still to come. The possibilities are endless when you can instantaneously tap into the collected knowledge and creativity of the entire human race! That's a pretty awesome power for kids like me to have at our fingertips, and it's all thanks to the internet, the undisputed greatest invention ever.篇2The Greatest Invention EverHave you ever wondered what the greatest invention of all time is? I have, and I think I've figured it out - it's the internet! The internet is the most amazing, wonderful, and mind-blowing invention that has ever existed. It has completely transformed how we live our lives and lets us do so many incredible things.First of all, the internet allows us to learn about absolutely anything we want, anytime we want. Back in the old days before the internet, if you wanted to find out about something, you hadto go to the library and look it up in books and encyclopedias. But now, you can simply search on the internet and find all the information you need in seconds! You can learn about animals, planets, history, science experiments, instructions for tying knots or doing magic tricks - literally anything your heart desires. The wealth of knowledge available at our fingertips is just astounding.Not only that, but the internet lets us watch unlimited videos and shows from all over the world. Whether you want to see funny pet videos, incredible science documentaries, old classic movies, or the latest music videos, it's all right there. You'll never get bored again! My favorite thing is watching toy unboxing and review videos to see all the newest, coolest toys before I ask my parents for them.Speaking of parents, the internet has also enabled us to connect with people anywhere on the planet. I can video chat with my grandparents who live across the country and it's almost like they're right there with me. I can also talk to my friends even when we're not at school through messages, video games, and so much more. We're constantly sharing memes, videos, and chatting about our interests. The internet has brought the world closer together.Furthermore, the internet provides endless entertainment through games, apps, and websites. You can play multiplayer games with people from all over, try out new apps that do amazing things like turning you into a cartoon character, and watch hilarious videos and comedy sketches. There's always something new to explore and experience.Ordering food or shopping for anything you can imagine is also possible with the internet. You can have pizza, burgers, ice cream, or any food delivered right to your door. You can buy toys, books, video games, art supplies - really anything - with just a couple clicks. And it all shows up at your house after just a couple days! How convenient is that?Overall, the internet has to be the greatest invention ever created. It gives us access to infinite knowledge, amazing entertainment, the ability to connect with anyone worldwide, awesome games and apps, and the convenience of ordering whatever we need. I can't imagine living without the internet - it has made our lives so much better and more fun. Whoever invented it is a total genius! The internet really and truly is the most incredible thing ever invented.篇3The Greatest Invention EverHi there! My name is Jamie and I'm 10 years old. Today my teacher Miss Wilson asked us to write an essay about what we think is the greatest invention of all time. At first I didn't know what to pick - there are so many amazing things that have been invented over the years!After thinking about it for a while, I decided to write about something that I use every single day and can't imagine living without - the internet! I know the internet isn't just one single invention, but a bunch of different technologies and computer networks all linked together. But in my opinion, it's the most mind-blowing and life-changing invention humankind has ever come up with.The internet is sort of like a giant brain that contains basically all the knowledge in the world. Whenever I need to find out about something for school, or just because I'm curious, I can "ask" the internet and it will give me the answer in seconds. My parents always say how lucky kids today are compared to when they were young and had to go to the library and look through books for hours just to get basic information.But the internet is way more than just an endless library of facts. It connects people from every corner of the globe and letsus communicate in amazing ways. I can chat with my cousins on the other side of the world through video calls with just a couple clicks. I can watch videos about anything you can imagine - from science experiments to ninja movies to tutorials on how to do cool magic tricks. The internet brings amazing entertainment and education right to my fingertips.The internet is also how I play a lot of my favorite games. Sure, there are games you can play alone on a computer or console. But some of the best ones let you team up with friends online, talking to each other while shooting monsters or exploring virtual worlds together. I've made so many new friends through online games that I wouldn't have met otherwise. We may live in different countries, but it feels like we're in the same room when we're questing and battling online.Speaking of virtual worlds, the internet is opening up new mindblowing experiences called the "metaverse" which are kind of like the internet, but in 3D virtual reality. With a VR headset, you can join co-workers or classmates in amazing digital spaces that look like they're completely real. You can learn with 3D models, attend concerts with your favorite artists, or even travel to far-away places without leaving home. The metaverse is stillpretty new, but I'm convinced it's going to be the future of the internet and change how we experience the world.I could go on and on about how amazing the internet is for shopping, ordering food, sharing creativity through things like YouTube and social media, and so much more. But what really makes it great for me is how it opens up opportunities I couldn't even dream of just a couple decades ago. My grandparents didn't have the internet when they were kids and they can hardly believe all the things we're able to do with it today.The internet has made the world a much smaller place by connecting people and ideas across vast distances instantly. My friends and I can collaborate on group projects together even though we live in different towns. If I need an expert to help me with something, like learning a new coding language, I can find online teachers and tutorials instead of being limited to what's available locally.While many amazing inventions have transformed our lives, I truly believe the internet and everything it enables is the most important and impactful of all time so far. Its inventors maybe didn't fully realize just how huge and revolutionary it would become. The internet isn't perfect - there are downsides like too much screen time, cyberbullies, and privacy worries. But in myopinion, its upsides in spreading knowledge, enabling human connections, and unlocking creativity far outweigh the negatives.The internet has made our world a richer, more accessible, and more opportunity-filled place than ever before in human history. In just a couple decades, it has fundamentally changed how we live, work, learn, and connect as a global society. And we're still just scratching the surface of how transformative it may eventually be. Whatever new inventions come along, I don't think anything will ever top the internet and how it has expanded our universe of possibilities as the greatest invention ever!篇4The Greatest Invention EverWhat is the greatest invention of all time? Some people might say the wheel or the lightbulb or even the internet. But in my opinion, the greatest invention ever is something that has changed all of our lives in amazing ways - it's the smartphone!Smartphones are so incredibly cool and useful. They put the power of a computer right in your pocket or backpack wherever you go. With a smartphone, you have access to basically all of human knowledge with just a few taps on the screen. Need to know what the capital of Australia is? Just ask your phone. Wantto see pictures of planets and galaxies? Easy. Have a question about ancient Egypt? The answers are right there.But smartphones are way more than just miniature encyclopedias. They are little entertainment powerhouses too. You can play awesome games, watch hilarious videos, listen to music, and even make your own movies and songs if you want. Whenever I'm bored, I just pick up my phone and I'm instantly transported into worlds of fun and adventure.Speaking of transportation, smartphones have maps and navigation too. That means you'll never ever get lost again, even in a big confusing city. The phone uses satellites to precisely track your location and give you turn-by-turn directions to wherever you need to go. How amazing is that?For me though, the best part about smartphones is how they keep me connected to my friends and family. Using apps like Snapchat, Instagram, and TikTok, I can instantly share pictures, videos, and messages with my buddies. We're constantly cracking jokes, reacting to each other's posts, and having fun conversations. Smartphones help us keep our friend groups alive and thriving.Smartphones have cameras too - really, really great cameras that can take publication-quality photos and videos. I love beingable to capture special moments with perfect clarity. Whether I'm at a birthday party, on vacation, or just hanging out, I can snap high-definition pics that will preserve those memories forever.As if all that wasn't enough, smartphones are also productivity powerhouses that help me stay organized and get my work done. There are amazing apps for notetaking, scheduling, researching, writing papers, making presentations, and so much more. Instead of struggling with clunky software on a desktop, I can create and edit documents easily from my phone.And let's not forget about reading. These days, I can have an entire library of books loaded on my smartphone. Whether I'm into fantasy novels or biographies, comic books or classic literature, it's all right there. My phone is my portable personal bookshelf that travels everywhere with me.There's even more I could say about how great smartphones are. They have voice assistants like Siri that can set reminders, send messages, and look up trivia just by asking out loud. Many smartphones are also water resistant and shockproof, making them tough adventuring companions for outdoors exploring. And with mobile payment systems, I can make purchases from my phone with just a tap.When you add up everything a smartphone can do - educate and entertain, provide navigation and communication, act as a camera and productivity tool - it's truly a modern marvel. These pocket-sized devices give us abilities that would have seemed like magic just a couple decades ago.Nothing has transformed daily human life quite like the ubiquitous smartphone. From helping with homework to playing games to capturing priceless memories, these devices enhance our existence in so many ways. They represent the culmination of humanity's scientific genius and our ability to innovate amazing technologies.That's why in my opinion, the smartphone is the single greatest invention ever. It's more than just a gadget – it's a symbol of our progress as a species. Smartphones remind us that we are capable of incredible achievements when we set our minds to reshaping our world through ingenuity and creativity. With further advancements surely still to come, the humble smartphone may just be the first step into an astounding future of innovation. I can't wait to see what comes next!篇5The Greatest Invention of All TimeWhat do you think is the greatest invention ever made? Maybe you're thinking of something super cool like video games, smartphones, or even candy! Those are all awesome inventions that have made our lives a lot of fun. But in my opinion, the greatest invention of all time is something that changed the world in a much bigger way. It's an invention that has helped billions of people and made it possible for us to live the comfortable lives we have today. Can you guess what it is?The greatest invention ever is... electricity! That's right, I'm talking about the power that lights up our homes, runs our computers and TVs, and keeps our refrigerators cold. Electricity has completely transformed how we live, work, and play. Without it, the world would be a very different and difficult place.Way back before electricity was invented, people had to rely on fire for light and heat. They would burn wood, candles, or oil lamps to be able to see at night. But fires are dangerous, smoky, and hard to control. With the invention of electricity and light bulbs, we can flip a switch and have bright, clean light whenever we need it. No more burning down your house just to be able to read a book after sunset!Electricity also powers so many modern inventions that make our lives easier. Can you imagine living without arefrigerator to keep your food fresh? Or not having a washing machine to clean your clothes? What about not having any computers, TVs, video games, or other electronics? Life would be pretty hard if we had to go back to the old ways of doing everything by hand without any machines to help.Even basic things like heating and cooling our homes depend on electricity nowadays. In the winter, we use electric heaters, furnaces, and other devices to stay nice and warm inside when it's freezing cold outside. In the summer, we have air conditioners to keep cool instead of sweating like crazy. Modern buildings are designed to use electricity to control the temperature so we're always comfortable.But electricity doesn't just make our homes better - it has also allowed for huge advances in technology, communication, transportation, and so much more. The internet, which lets us video chat with people on the other side of the world and look up any information we want in seconds, runs on electricity. Phones, computers, and TVs all need electricity to work. Even the cars, trains, and airplanes that get us places use electric signals and controls.Hospitals use tons of electric machines to help diagnose and treat people. Things like X-ray scanners, heart monitors, andoperating equipment all need a constant supply of electricity. Without it, doctors and nurses wouldn't be able to help people as well.Electricity also powers the modern factories and machines that make all the products we use every day - our clothes, toys, furniture, and food containers are all manufactured using electricity. Even old inventions like the printing press work better with electric motors instead of being hand-cranked.As you can see, electricity is absolutely essential to almost every part of our lives today. It has allowed for countless other inventions and makes the world a much more comfortable, efficient, and amazing place. While there are definitely other huge inventions throughout history, like the wheel, the printing press, vaccines, and the internet, I don't think any of them have had as big of an overall impact as the harnessing of electricity.Generating and distributing electricity on a huge scale does have some negative impacts on the environment when it comes from burning dirty fossil fuels like coal and oil. But as we develop more renewable energy sources like solar, wind, and water power, electricity can become an extremely clean and sustainable way to power our modern world.So the next time you flip on a light switch, charge your phone, or play a video game, remember that none of it would be possible without the incredible invention of electricity. It has revolutionized how we live and allowed for so many other amazing technologies to be created. In my book, the bright idea of harnessing electricity will always be the greatest invention of all time!篇6The Greatest Invention EverWhat is the most amazing, awesome, and best invention of all time? That's a really tough question because there have been so many great inventions throughout history. After giving it a lot of thought, I think the greatest invention ever has to be the internet.The internet is just so incredibly useful and has changed our lives in so many ways. Before the internet, if you wanted to learn about something, you had to go to the library and hope they had a book on the topic. And those books were often old andout-of-date. But now with the internet, you can simply search online and find the latest, up-to-date information on absolutely anything you can imagine! Want to learn about ancient Egypt?The internet has thousands of websites to teach you. Curious about how airplanes fly? YouTube has endless videos explaining it. The internet is like having the biggest library ever, right at your fingertips!Not only is the internet an endless source of knowledge, but it also connects people all around the world. Thanks to video chat, you can actually see and talk to relatives or friends living on the other side of the planet! My grandparents live in another country and I get to video chat with them every week. Without the internet, we wouldn't be able to see their faces or hear their voices that often. The internet also lets you make new friends that you can chat and play games with, even if they live halfway across the world. It's crazy to think how easily we can communicate with absolutely anyone these days.Another amazing use of the internet is for entertainment. Whenever I'm bored, I can hop online and watchmy favorite movies, TV shows, or YouTube videos. There are millions of songs and games online too to never let you get bored. The internet is like an infinite source of entertainment that you can access anytime! Before the internet, kids had to settle for whatever was on TV or go outside to play. But now we have this vast digital playground to keep us endlessly amused.Speaking of playgrounds, the internet is also revolutionizing how we learn in school as well. Our teachers use interactive websites and games to make lessons way more fun and engaging. We can go on virtual field trips to explore ancient ruins or the depths of the ocean, all from our classroom. The internet brings the entire world into our school. It's education like no other time in history.And who knows what else the internet will make possible in the future? Maybe we'll have virtual reality classrooms where we can learn by experiencing things ourselves. Or instantaneous translators so we can communicate with anyone in the world seamlessly. With the internet constantly evolving, there's no limit to what's possible.Some people might say inventions like the wheel, electricity, or antibiotics were more important, but I think the internet combines and builds upon all the previous great inventions. It's a manmade thing that has profoundly transformed how we live, learn, communicate, and are entertained. No other invention has so deeply reshaped human experience and opened up a world of possibilities like the internet has. It's awesome how we have the sum of human knowledge at our fingertips and can connect withothers across the globe with a few taps. The internet is truly the most epic, mind-blowing invention ever created!So while fire, the printing press, automobiles, and all our other inventions are amazing in their own ways, none of them can match the sheer awesomeness of the internet. It has made the world a dramatically different place in just a couple decades. For a kid nowadays, the internet is indispensable to our lives and integral to everything we do. We're the first generation that can't even imagine existing without it! If aliens came to Earth and asked what our species' single greatest achievement was, I'd have to show them the internet. It's simply the most unbelievable, universe-changing invention humankind has ever created. The internet is, without a doubt, the G.O.A.T – the Greatest Of All Time!。

我眼中最伟大的发明手机英语作文
我眼中最伟大的发明手机英语作文全文共3篇示例，供读者参考篇1The Greatest Invention in My Eyes: The Mobile PhoneImagine a world without mobile phones. It's hard, isn't it? Mobile phones have become such an integral part of our lives that it's difficult to picture a reality where we can't instantly communicate with our loved ones or look up information on the internet at any time. In my opinion, the mobile phone is the greatest invention ever created by human beings.When I think about all the amazing things that have been invented throughout history, the mobile phone stands out as the most impressive and life-changing. Sure, the wheel was a pretty cool invention that made transportation a lot easier. And the lightbulb was great for letting us see in the dark. But the mobile phone? It's in a league of its own!The first mobile phone call was made on April 3, 1973 by Martin Cooper, a researcher at Motorola. He called his rival at Bell Labs to let him know he was speaking on a mobile phone. Can you imagine how mind-blowing that must have been at thetime? A phone that you could carry around with you and use anywhere? It was like science fiction becoming reality!In those early days, mobile phones were huge, heavy bricks that could only be used for making voice calls. But as technology improved, they became smaller, lighter, and could do so much more. Nowadays, our smartphones are like handheld computers that make the old mobile phones look like toys.With our smartphones, we can do almost anything. We can make video calls and see our loved ones' faces even if they live on the other side of the world. We can send text messages, photos, and videos in an instant. We can get directions to anywhere we want to go, look up facts on any topic imaginable, play games, watch movies, listen to music, and so much more –all from this little device that fits in our pockets!Mobile phones have changed the way we communicate, learn, work, and even have fun. Think about how much easier it is to stay in touch with our families now. My mom can call or text me whenever she needs to, and I can let her know if I'm going to be home late from school. My dad can look up information on his phone to help me with my homework. I can video chat with my grandparents who live far away and feel like they're right there with me.In emergencies, mobile phones can even save lives. If someone gets hurt or is in danger, they can quickly call for help. My friend's dad was in a car accident once, but he was able to use his phone to call an ambulance right away. Without a mobile phone, who knows how long he would have had to wait for help?Mobile phones have also changed the way we work and learn. Business people can check their emails, make video calls, and get work done from anywhere. Students can use their phones to look up information, take notes, and even attend online classes. My teacher sometimes has us use our phones in class to look up facts or work on educational apps and games. It's like having a portable library and toolbox all in one device!Of course, like with any technology, there are downsides to mobile phones too. Some people get too distracted or addicted to using them. Cyberbullies can use phones to send mean messages. And there are concerns about things like privacy and screen time. But overall, I believe the benefits of mobile phones far outweigh the negatives.Imagine trying to live your life today without a mobile phone. It would be so inconvenient! You couldn't easily call or text your friends and family. You'd have to carry around maps and dictionaries instead of having that information at your fingertips.You'd miss out on being able to look things up, take photos, watch videos, and have access to a world of knowledge and entertainment wherever you go.In my eyes, the mobile phone is the greatest invention of all time because of how much it has revolutionized communication, learning, work, and our ability to stay connected with each other and access information. It has made our lives so much more convenient, efficient, and fun. The mobile phone has truly changed the world, and I can't imagine living without it.So the next time you pull out your phone to make a call, send a text, look something up, or play a game, remember how amazing that little device really is. It's a modern marvel that has transformed human civilization in countless ways. The mobile phone is an invention that deserves to be celebrated and appreciated for its incredible impact on our world.篇2The Greatest Invention in My Eyes: The Mobile PhoneHave you ever thought about what the greatest invention in the world is? Some people might say the wheel, others might say the light bulb or the airplane. But in my opinion, the greatest invention ever is the mobile phone! Mobile phones are tinycomputers that fit right in our pockets and allow us to do all sorts of amazing things. I love my mobile phone and I think it's the coolest gadget ever created.Mobile phones make our lives so much easier and more convenient. In the past, if you needed to call someone, you had to find a payphone or use a home landline. But now with mobile phones, you can call anyone from anywhere at any time! My parents and I can stay in touch no matter where we are. If I'm at a friend's house playing, they can easily call me when it's time to come home for dinner. If we're running late coming home from a trip, my parents can call our neighbors to let them know. Having a mobile phone means you're always connected and can reach people instantly.Another amazing thing about mobile phones is that they put the entirety of human knowledge at our fingertips. If I'm doing homework and I don't understand a concept or need to look up a fact, I can use the internet browser on my phone to search for information and learn. I can read encyclopedia entries, watch educational videos, translate languages, and get answers to any question I can think of -- all from my mobile phone! It's like having a tiny portable library and teacher with me all the time. My parents didn't have that luxury when they were kids.Of course, mobile phones are also incredibly useful just for entertainment and fun. I can play games, watch movies and shows, listen to music, and more -- again, all from this little device in my hand. If I'm bored waiting somewhere, I can pull out my phone and instantly have something to do. I can text and share funny memes with my friends. I can take pictures and videos whenever I want to capture a fun moment. Mobile phones keep us entertained, let us express our creativity, and make even mundane daily activities (like waiting in line) less boring.Thanks to apps, our phones can do practically anything. There are apps for ordering food, getting driving directions, checking the weather, reading books, and so much more. Many apps are free and others just cost a few dollars, yet they provide amazing utilities right on our phones. I use a homework app to keep track of my assignments and due dates, a brain training app to work on math and reading skills through games, and even a mobile banking app to watch over my small allowance savings. With all these apps, our phones are like a magic toolbox we can use to handle all sorts of tasks.Some people worry that mobile phones are bad because kids can get addicted and spend too much time staring at their little screens instead of playing outside. And I admit, sometimesit can be hard to put my phone down when I'm really engaged in a game or texting friends. But my parents make sure I don't overdo it by setting time limits and rules. I still spend plenty of time playing outside, reading books, and doing other activities away from screens. As long as we practice moderation and balance, mobile phones are an incredible tool that makes our modern lives so much richer and more convenient.In school, we've been learning about the history of communication technologies and important inventions throughout history. We started with things like the printing press, the telegraph, radios, and telephones. Each new invention revolutionized how humans could communicate and share information. But in my opinion, none of those old inventions can compare to the awesomeness of the mobile phone! The mobile phone builds upon all those past breakthroughs in communication and computing, and packages them into one unbelievably powerful pocket-sized device.Other kids in my class picked the television, personal computers, or the internet as the greatest invention. Those are all really amazing and important inventions too, for sure. But I still think my pick of the mobile phone is the best. That's because the mobile phone combines so many utilities into one gadget: it's acommunication device for calling and texting, an educational tool for accessing info on the internet, a pocket computer, a camera, a music player, a gaming platform, and more -- all rolled into one lightweight portable package. Nothing else in the world packs so much power and versatility into such a small frame. That's why I believe the mobile phone is the greatest invention humanity has ever created.Each new generation of mobile phones keeps getting more advanced too, with bigger bright screens, faster processors, better cameras, and extra cool new features. Sometimes I imagine what mobile phones might be like 20 or 30 years from now, and I can't even picture how amazingly futuristic they'll be. Maybe they'll have holographic 3D displays or project virtual reality worlds into our eyes. Maybe they'll interface directly with our brains through just thoughts and gestures. Or maybe they'll be implanted somewhere inside our bodies as bio-computers. Whatever weird and whiz-bang abilities they gain next, I'm sure mobile phones will just keep getting more incredible as time goes on.So that's my case for why the mobile phone is the greatest invention ever: it's ultra convenient, puts a world of knowledge at our fingertips, provides endless capabilities through apps,bundles multiple utilities into one gadget, and is super fun! Having a mobile phone makes my life easier, smarter, and way more entertaining. To me, there's just no competition when it comes to naming the most impactful and useful invention created by humans so far. My mobile phone is simply the best!篇3The Greatest Invention in My Eyes: The Cell PhoneI'm sure lots of adults and even some kids would say things like computers, the internet, or airplanes are the greatest inventions ever. But in my opinion, the greatest invention of all time is definitely the cell phone! I know it might seem kind of silly for a kid to pick a cell phone over all those other amazing inventions. But just hear me out on why I think cell phones are so awesome and useful.First off, cell phones make it super easy to stay in touch with my family and friends no matter where I am. With a cell phone, I can call my mom when I'm at a friend's house to let her know I'm okay. Or I can text my dad silly jokes when he's at work to hopefully make him laugh. I can even video chat with my grandparents who live far away which is way more fun than justtalking on a regular phone. Without cell phones, keeping in touch would be so much harder!Cell phones also make me feel safer when I'm not with my parents. Let's say I was at the park or mall with just my friends. If anything went wrong or we needed an adult for some reason, I could quickly call my mom or dad for help. Or if I ever got lost or couldn't find my parents, I could use my cell phone to contact them or even use maps to figure out where I am. Plus my parents can always check in on me by calling or texting my cell. I'm sure my mom and dad feel a lot better about me being out when they know they can easily reach me.Another reason I think cell phones are the best is because they give me a tiny computer I can carry everywhere! I can use my phone to look up information for school projects, get directions if I'm lost, take pictures and videos, listen to music, watch shows and movies, read books, and even play games. It's like having a mini portable laptop, camera, music player, tv, and game console all in one device that fits in my pocket. That's so cool and convenient!Speaking of games, I have to admit that being able to play fun games on my phone is a huge plus as a kid. These days, a lot of the best games are made for mobile phones first before theycome to game consoles. I can play multiplayer games with my friends who all have phones too. We can team up, compete, chat, and cooperate together even when we're not in the same room. Playing games on phones portable and social in a way that older game systems could never be.I know some parents and teachers worry that kids these days are too glued to their phones. But in my opinion, cell phones are educational tools just as much as they are entertainment devices. There are so many great educational apps and websites that help me learn and practice things like math, spelling, geography, coding, and more. My phone gives me a fun, interactive way to learn outside of school. Teachers are even starting to use cell phones as teaching aids by having students watch videos, research topics, take quizzes, and participate in educational games and activities right on our phones.Of course, probably the number one reason I love cell phones so much is how they've become the central communication tool for my whole generation. Calling people is basically obsolete for me and my friends - we use text, video chat, and messaging apps like WhatsApp to constantly stay connected throughout the day. We can easily share pictures, videos, links, and more without any hassle. Group chats allow me to makeplans and discuss my interests with all my friends at once rather than having to track people down one-by-one.Social media apps are also huge on our phones. I can post updates, follow my interests, watch trending videos and memes, and see what's going on with my friends all through apps on my mobile device. Heck, even a lot of the biggest celebrities, YouTubers and online personalities interact with fans and share content straight to everyone's phones these days. Our phones are truly windows into global communication, entertainment, and culture.Now I'm sure some people might read this and think "Geez, this kid is way too obsessed with his phone! What's so great about those silly devices?" And you know what? A few years ago, I might have agreed with that. When I was really little, I definitely didn't appreciate cell phones as much as I do now that I'm a bit older. I just thought they were kind of boring and cheap replacements for things like real cameras, game consoles, laptops etc.But as I grew up more surrounded by mobile technology and social media, I realized cell phones aren't just convenient combinations of older tech - they enable totally new forms of communication, learning, and entertainment that weren'tpossible before. Sure, I could use a separate digital camera, music player, portable gaming device and laptop to do all the things my phone does. But having it all combined into one lightweight, pocketable gadget that I can use virtually anytime and anywhere is simply revolutionary!I get that some skeptics might say "But plenty of other inventions like the internet, antibiotics, automobiles or electricity have way more importance than phones!" And they're not totally wrong - those inventions are incredible developments that revolutionized the world in huge ways. But in my opinion, cell phones are the most seamlessly woven into the daily life and culture of my generation. They're how we socialize, learn, play, navigate, capture moments, and understand the world around us more than any other technology.Maybe to adults, cell phones are just handy tools for communication and organization. But to me and my friends, they're lifelines to our social lives, identities, interests, and education in a way no other device has been before. Our phones are windows into a whole new culture of real-time global connection and infinite information. To us, they truly are the greatest inventions we've ever known!So while respected grown-ups might pick more "important" inventions, I'm sticking by my opinion that cell phones are the most impactful, revolutionary, and flat-out awesome technological development, at least from a kid's point of view. Thanks to cell phones, my generation has opportunities for communication, education, and creativity that would have seemed like science fiction to kids of the past. For that reason alone, I think mobile phones deserve to be considered the greatest invention in my eyes!。
The Greatest Invention In My Eyes
The Greatest Invention In My EyesWhen it comes to "the greatest invention", the word "computer" strikes me. Computer has changed my or our life in my eyes, and the official document said one of the most prominent human invention and contribution in the 20th century is to develop the electric computer as well.I just have a vague conception of the initial computer. It doesn't matter inn fact. Van Neumann (the person called "father of modern computer") will not hold you back from using conputer only because you don't know him. As a result, I can feel no qualm about playing the computer but knowing nothing about it.Generally speaking, computer has melted into people's life all over the world. At a rough estimate, there are 20 thousand more newcoming Internet users every year in China. In our daily life, we always work, study, communicate, and entertain ourselves with it.For further details, officers can inform other workers of a certain meeting. You can get your wages by account transferon bank's computer rather than reach out for it in person. As for study, what I can say is much more. Teachers in college giveus lessons by PowerPoint; students preview no the Internet; librarians manage books of lending and borrowing by some system; English learners download MP3 from the Internet;.......Personally speaking, computer is used to contact others and have fun more often. If I were at home, the time of playing computer almost equals to the time of sleeping. QQ, MSN, e-mail, Blog and other communication tools shorten the distance between my friends, my parents and I. Especially, I love to write my Blog as diary. It's a pleasure to imagine how moved I'd feel if I read all the words written by myself one by one. Entertainment is also important. I can watch films, listen to the music,search for news, read novels or something with the help of computer.In brief, computer have had a close relationship with us whether in broad or narrow aspect.Nevertheless,every coin has two sides. What computer to us is what DDT to environment. DDT kills pests as well as do damage to other lives. Computer helps us as well as do harm to us. The case that some teenager died in front of computer desk is not difficult to learn. In addition, the most typical example is that my eyes have broken because of staring the screen for too long time. Don't worry. Not everyone has the "persistence" to play it for nearly all day after all.In conclusion, computer do more good than harm to us. It still is the greatest invention in my eyes.(WORDS:450 SCORE:95)Ladies and gentlemen,Good evening!My name is Diana,and I come from Shanxi Datong.It's a very valuable opportunity for me to stand here,and whatI want to talk about today is "The Greatest Invention In My Eyes".I'm part of a new creation in a global sociaty,I saw many great invetions.But can you imagine what situation it will become if we have no clothes?Let me take you to the formally,I read the diaries of Adam and Eve.Atfrist,Adam felt this creature with long hair is a good deal in his way,he was not used to company.She told him her name is Eve,and she was made out of a rib taken from his body.They livedtogether.Oneday,the plan was in a frantic commotion in one moment,and every beast was destroying its nabour.Adam went away inmuch hase,then Eve came curtained in bush and bunches of leavs.When he asked her what she meant by such nonsese,then told her to snatch them away and throw them down,she tittered and blushed.Adam was hungry,so he ate the best apple,by doing that,he did the same as Eve.Yes,they had eaten the forbidden fruit.No need to say,clothes are the greatest invention in my eyes,unless,human beings have thick and long fur.Clothes is a little thing,but it has an important effect.On one hand,it can resist cold,keepwarm;on the other hand,it can beautify ourbodies.Especially,every body likes fashion in this modern time.Clothing fashion is holding a more and more important position.Finally,I want to conclued that clothes are the greatest invention in my eyes.We have clothes,so we needn't walk naked in the Street,and we needn't use bush and bunches of leaves to curtain our bodies like Adam andEve.We become civilized human bengs.Thank to clothes!Thank you!。
TheGreatestInventionInMyEyes
TheGreatestInventionInMyEyesThe Greatest Invention In My EyesLadies and gentlemen,I would like to tell you about an unusual assignment. I was surprised and amused when our teacher told us our homework was to write a article which is in the form of speech ,but I think it is my pleasure to finish it without experience.When you look at the lovely cartoon, play with a charming dolls, sit on the fast train, answer of the 20th century chapters, we found that human in the one hundred years not only experienced the baptism of fire and blood, but also created innumerable wonders. In the 21 st century, as a great invention of the network is everywhere.While there are so many great inventions appear frequently, from the perspective of me, the greatest invention is network. The detailed reasons are as follows. First of all, chat on Internet helps us develop good friendship with other person,at the same time,strengthen our social abilities.Then,it has positive effect on study as well as life.Such as:we can search for a plenty of information which is of great value to our study.Moreoreover,Internet lays the brick of happy life,so we can find out the best idea to live life to the fullest. Next,we open our horizons by skinning good webpage,watching at great video and listening to the voice on the network,which have tremendous benefits to us. The openness of the network and convenience, content of variety and diversity, for young people, provides a broad study space, greatly broaden the adolescents' knowledge way, help teenagers broaden our horizon and promote academic. Set it an example:the Internet can also beyond time and spaceand economic constraints, in the school education online,no matter what problem you have, you can at any time through E-mail request the teacher's instructions. And the world of Internet interactive learning, rich 3 d graphics display, language interpretation and other multimedia content, make learning easier, interesting, this is any textbooks may not have.What is more,when we are listening to our favorite music and playing computer games at times,we can relax ourselves as much as possible, our depressions and stress are released very well.Furthermore,we can grasp many things.For example,songs and dances to improve the quality of life, playing computer games can sometimes help develop our intelligence and the ability to solve various kind of problems, .we can have a lot fun and enrich our tedious life.Besides, Many merchants into the network, to provide online shopping services for customers. Through the network, then you can sit in the home, in online purchasing items and enjoy is door-to-door service. What counts most is that you save the time shopping, and can be goods than N home, chances are that you will buy the good and cheap goods.While network may have adverse effect ,it is a double-edged sword.Neverthless as long as we weigh its advantages and disadventages,in addition,take the essence and discard the dregs,we will be very good use of the network.You may hold different ideas, I just represent me personally. No matter what opinions you have, I still think that the network popularization trend not only won't attenuation, and may even increase. My speech is over, thank you very much.to an overseas call, you ever realize the power of network, Turn the magnificence。

世界上最伟大的发明英语作文轮子 100字
世界上最伟大的发明英语作文轮子100字全文共6篇示例，供读者参考篇1The Greatest Invention in the World: The WheelWheels are everywhere! They're on cars, bikes, skateboards, and even office chairs. But did you know that the wheel is one of the most amazing inventions ever? It's so cool and useful that I think it might just be the greatest invention in the whole world!Way back in ancient times, people had to carry everything themselves or make animals pull heavy loads. It was really hard work. Then one day, some genius figured out that a rolling object is way easier to move than something being dragged across the ground. And just like that, the wheel was invented!The first wheels were probably just round slices of wood from tree trunks. But even those simple wooden wheels made people's lives so much easier. Imagine pushing a heavy cart instead of carrying all that stuff yourself. No more sore backs!As time went on, people made wheels better and better. They used stronger materials like stone and metal. They madethe wheels bigger for climbing over obstacles. They even added grooves and treads so wheels could roll smoothly over bumpy ground.Wheels led to some other awesome inventions too. Carts and wagons for carrying heavy loads. Chariots for racing and going to war. The wheelbarrow for hauling stuff around construction sites. And of course, modern vehicles like cars, trucks, buses, and trains that take us wherever we need to go.But wheels aren't just for transportation. There are wheels in clocks, windmills, watermills, and all sorts of machines. Bikes have wheels to make pedaling easier. Even toys have little wheels, like toy cars and skateboards. Wheels are literally everywhere you look!That's why I think the wheel has to be the greatest invention ever. It makes our lives so much easier and more fun in a million different ways. Wheels help us move heavy stuff, travel long distances, and build awesome machines. Wheels are just the best!Sure, other inventions like fire, electricity, computers, and smartphones are amazing too. But in my opinion, none of those would be possible without the simple genius of the wheel. That very first rolling object changed everything for humans.The next time you see a wheel, like on your bike or in a moving car, remember how incredibly useful and important it is. Wheels make the world go round! So take a minute and thank whoever invented the first wheel a bazillion years ago. That person totally changed human history forever with one rolling idea. Now that's what I call a great invention!篇2The Greatest Invention in the World: The WheelWhoa, did you know that the wheel is like the coolest, most awesome invention ever? It's so great and I love wheels! They are definitely the greatest thing that was ever invented by people. Let me tell you all about why wheels are just the best.First of all, wheels help us get around really easily. Without wheels, we'd have to walk everywhere or get pulled in a sled by horses or something. But with wheels, we can ride in cars, trucks, buses, bikes, scooters, roller blades, skateboards and so many other cool things with wheels! Wheels let vehicles go fast and not get stuck in the mud as easily. I love racing my bike with the wheels spinning super fast. Wheeeee!Wheels also help us move really heavy stuff around. Like if you tried to push a big couch across the floor, it would be superhard and you'd get all sweaty. But if you put wheels on that couch, you could push it easily peasy lemon squeezy! Wheels take away a ton of friction so heavy things can glide along smoothly. That's why we put wheels on shopping carts, dollies, rolling suitcases and more.Plus, wheels are used in so many great machines that make our lives better. The washing machine uses a cylinder that spins around thanks to wheels. The dishwasher has those cool spinning spray arms with wheels. Clocks and watches have gears with wheels that make the hands go around. Omg, even this computer I'm typing on has a scroll wheel to make the screen go up and down! How handy is that?And don't even get me started on skateboards, rollerblades, roller skates and other toys with wheels. Those are just mega fun to play on! I love racing my friend down the block and doing tricks in the skatepark. Shredding up and down ramps is a total blast. Wheels make playing way more exciting and adventurous than just running around on your feet.You know what else is awesome? Ferris wheels! Those huge wheels at carnivals and fairs take you high up in the sky to see everything down below. Riding in the swinging carts is both scary and thrilling as the wheel slowly turns round and round. Ialso love spinning myself around and around really fast on a swing set or merry-go-round at the park. Weeeeeee!Basically, wheels have revolutionized how we move and transport stuff. They reduce friction like crazy, allowing us to haul heavy loads easily across smooth surfaces. We use wheels for tools, toys, machines and all kinds of vehicles like bikes, cars and planes. Without the brilliant invention of the wheel, we'd be stuck pulling heavy sledges everywhere and walking absolutely everywhere too. No thanks!So in my opinion, the wheel is 100000% the most amazing, useful, fun invention ever created by human beings. Wheels make our lives so much easier, faster and better. I'm so grateful that ancient people long ago were genius enough to come up with the very first wheel. Three huge cheers for the wheel - hip hip hooray! Hip hip hooray! Hip hip hooray! Let's hear it for the greatest invention ever!篇3Here's an essay of around 2000 words on "The Greatest Invention in the World: The Wheel" written in a style suitable for an elementary school student:The Greatest Invention in the World: The WheelHave you ever wondered what the greatest invention in the whole wide world is? I think it's the wheel! The wheel is super awesome and has helped people so much. It lets us move things really easily from one place to another.The wheel was invented a really really long time ago, maybe like a bazillion years ago! It's so old that nobody really knows who invented it first. Some very smart people think it might have been invented in Mesopotamia or somewhere else in the Middle East. Isn't that totally crazy?The first wheels were probably just round wooden discs that were rolled along the ground. But later on, people made them out of stone and metal too. The coolest thing about wheels is that you can put them together to make awesome things move!Like what, you ask? Like cars, bikes, skateboards, roller skates, and so many other fun things! Wheels let vehicles drive super fast on roads. They also help machines like pulleys and gears work properly in factories. Wheels are everywhere once you start looking for them.But my favorite thing about wheels has to be the wheel on my bike! I just love riding my bicycle. The wheels let me go so fast and far. I can ride all around my neighborhood and the park nearby. It's the best exercise ever and so much fun!Wheels are also used on shopping carts, baby strollers, wheelbarrows, and all sorts of other things that need to be rolled. Just imagine how hard it would be to move stuff without wheels. You'd have to drag everything and it would be such a pain!The wheel has to be the most useful invention ever because it lets us move objects easily instead of having to carry them everywhere. It makes transportation by road so much easier whether you're driving a car, riding a bus, or just kickin' it on your skateboard.Wheels come in different sizes for different uses too. Tiny wheels are used in watches, clocks, and other small machines. Huge wheels are found on construction vehicles like bulldozers. The biggest wheel of all might be the ones on monster trucks - those are like the size of a house!To sum it up, the wheel is super duper great. It's helped humans get around and move stuff for thousands and thousands of years. We use wheels every single day without even realizing it. The wheel is in our cars, bikes, toys, and so many other things we can't live without.So the next time you go for a nice bike ride, say "Thank you wheels for being so awesome!" The wheel truly is the greatest, most revolutionary invention ever made. What would we dowithout this simple, yet brilliant creation? Not much, I'm afraid! Three cheers for the wheel - hip hip hooray!篇4The Greatest Invention in the World - The WheelHi everyone! Today I want to tell you about the most awesome invention ever created by humans. Can you guess what it is? It's the wheel! The wheel has to be the coolest and most important thing people have ever made. Without the wheel, our world would be super different and way harder.First of all, the wheel lets us have cars, trucks, buses, and all kinds of other vehicles that can drive on roads. Driving is so much faster than walking everywhere. My mom has to drive me to school every morning because it's too far to walk. If we didn't have cars with wheels, it would take us forever to get to school, the grocery store, or anywhere! We'd have to walk or ride a horse like people did a really long time ago. That would be exhausting.The wheel also lets us have bicycles, motorcycles, roller blades, skateboards and so many fun things with wheels that we can ride on. Bikes are my favorite because you can go pretty fast just by pedaling. I love feeling the wind rush past me when I cruise around the neighborhood on my bike. Skateboards areawesome too for doing tricks and riding around the skatepark. Without wheels, none of those radical sports and toys would exist!But wheels aren't just used for transportation and recreation. They're also super important for getting work done in factories, construction sites, farms and all sorts of other places. Big trucks and tractors with huge wheels can haul heavy loads of concrete, crops, logs and machinery from one place to another. At construction sites, cranes use wheels to move heavy steel beams and equipment around to build skyscrapers and bridges. My uncle is a farmer and he uses a tractor with massive wheels to plow his fields before planting crops.Wheels make it possible to move heavy stuff on carts, dollies and wagons too. That's how furniture, boxes and deliveries get rolled around easily. Desk chairs, inline skates, strollers and so many other things have wheels that make them glide smoothly. Even some of your toys probably have little wheels on them! Wheels reduce friction and effort needed to move objects over surfaces.In science class, we learned that the wheel is considered a simple machine because it's a basic tool that makes work easier. Along with levers, pulleys, screws and a few other things, thewheel is one of the oldest and most important simple machines. It lets us move loads straight horizontally using less force than dragging or carrying.The wheel was invented a really, really long time ago, but it's still super useful today. In fact, we use wheels more than ever before in our modern world with all kinds of vehicles, machines and devices. Most things that roll, spin or rotate use wheel technology in some way. The wheel keeps getting better too as engineers create new lightweight materials and designs.Just imagine how different life would be if the amazing wheel never got invented! We wouldn't have cars, bikes, skateboards or any other wheeled transportation. It would be so hard to move things around homes, cities, farms and factories. Work would be much more difficult and tiring. Travelling long distances overland would take forever and be exhausting. The world would be stuck in place without this ingenious invention!That's why I think the wheel is the greatest and most impactful invention created by humans. This simple but brilliant tool completely transformed how we can move across land with ease. The wheel revolutionized travel, transportation, labor, recreation and so much more. Life would be incredibly hard and limiting without this steady, rotating object that arrivedthousands of years ago but still roles along today, making our modern world go round.So let's hear it for the wheel - the humble but heroic innovation that keeps the world rolling along! What's your favorite thing with wheels? Let me know! Wheels for the win!篇5The Greatest Invention in the World - The WheelHave you ever thought about the greatest invention in the whole wide world? I have, and I think it's the wheel! The wheel is super duper important and makes our lives so much easier. Without the wheel, we wouldn't have cars, bicycles, skateboards, or anything that rolls. Can you imagine life without anything that rolls? No thanks!The wheel was invented a really really long time ago, maybe even as long as 6,000 years ago! Some very smart ancient people figured out that putting a heavy thing on a round shape made it way easier to move that heavy thing. They probably got tired of dragging heavy stuff across the ground. "There has to be a better way!" they must have thought.And boy were they right! Once they invented the wheel, they could put heavy things on little wheeled platforms and just push them instead of dragging. Genius! They used wheels to move big heavy building materials to make cool ancient buildings and monuments that are still around today, like the Pyramids in Egypt.But that's not all the wheel is good for, oh no no no. We use wheels every single day without even thinking about it! When you ride in a car or bus, those are wheels turning and helping you get places. When you ride your bike or scooter, it's the wheels that let you zoom around so fast. Even if you're just opening a door, you're using wheels - the little wheels on the hinges!My favorite wheels are the ones on skateboards and roller skates. I love feeling the wind in my hair as I rocket down the sidewalk. My wheels make that "rrrrrrr" sound and it's just the coolest. Sometimes I wonder what it would be like to have wheels attached to my shoes so I could roll everywhere I went. How awesome would that be?Some of the biggest, most massive wheels are on huge trucks and trains and construction vehicles. Those gigantic wheels help move incredibly heavy loads across the land.Without those big tough wheels, we couldn't build roads or railways or giant buildings. We wouldn't have factories to make all the stuff we need.And let's not forget about toys with wheels! Race cars, trucks, wagons, and lots more use those marvelous little wheels to scoot around and provide us with hours of fun. Playing with wheeled toys was one of the first ways I experienced the awesomeness of the wheel as a kid. Zipping my toy cars across the floor made me truly appreciate the genius invention of the wheel.Honestly, I can't imagine life without the wheel these days. It would be impossible to live without being able to roll and move things easily. We'd still be dragging everything across the ground like cave people! No bikes, no cars, no scooters or skateboards. That doesn't sound like much fun to me.The wheel is really a miracle if you think about it. Just a simple round shape that can roll and roll forever if you give it a little push. Yet it completely changed the world and lets us do so many amazing things with incredible ease. Buildings, transportation, toys, you name it - they all rely on the wheel.That's why I think the wheel is definitely the greatest invention in human history. It was a total game-changer that led to modern civilization as we know it. Pretty crazy that such ansimple, obvious idea once you see it could have such massive impacts over thousands of years!So the next time you hop in the car, ride your bike, or play with a rolling toy, remember to thank the geniuses who first invented the wheel all those centuries ago. We owe those ancient thinkers a huge debt of gratitude for creating something so useful yet so brilliantly simple. Three cheers for the wheel - the greatest invention ever!篇6The Greatest Invention in the World: The WheelHi there! My name is Timmy and I'm in 4th grade. Today I want to tell you about what I think is the greatest invention ever - the wheel! The wheel might seem like a simple thing, but it has totally changed the world. Without wheels, we wouldn't have cars, bikes, skateboards, or pretty much any other awesome vehicles to get around on. Can you imagine having to walk everywhere? No thanks!Wheels are basically just circular objects that rotate on an axle or axis. But don't let their basic design fool you - wheels are amazing! They help vehicles move way faster and smoother than if everything just had to slide along the ground. Wheels make iteasier to carry heavy loads too. Just look at a big semi truck - those huge wheel wheels let it haul tons and tons of cargo!The first wheels were probably just round slices of wood that people cut from tree trunks back in prehistoric times. Can you picture a caveman rolling a big log on some wooden rounds? Over time, people started adding grooves to the wheels to help them grip the road better. Then they made wheels out of stronger stuff like metal instead of wood so they wouldn't break as easily.There are so many cool types of wheels nowadays! Race cars have ultra thin and grippy rubber tires. Monster trucks have giant knobby wheels to drive over anything. Roller coasters and train wheels are specially designed to run perfectly on tracks. Heck, even inline skate wheels are a modern version of the wheel! My favorite wheels though? Definitely the kind on skateboards - those let you do awesome tricks.Beyond transportation, wheels are used in so many other awesome contraptions too. Clocks have gears which are kinds of wheels working together to keep time. Pulleys and winches use wheels to lift super heavy things. Tractors, lawn mowers, and all kinds of machines need wheels to work right. Wheels are literally everywhere you look!I can't even imagine what life would be like without wheels. We'd be pretty stuck, that's for sure! No subways, buses, or cars to get around cities. No bikes to cruise the neighborhood on. No way to quickly move heavy stuff around. Everything would take forever and be super hard! Even something as simple as a rolling office chair wouldn't exist without the wheel.So while wheels might not seem that impressive at first, they truly are one of the most important and revolutionary inventions of all time. Wheels let us travel, explore, build, and do so much more than we ever could without them. Three cheers for the amazing wheel - the greatest invention ever! Thanks for reading my essay. See ya later!。

最伟大的发明冰箱英语作文The Greatest Invention The Refrigerator。
The invention of the refrigerator is considered one of the greatest inventions of all time. It has revolutionized the way we store and preserve food, making our lives easier and more convenient. The refrigerator has become anessential appliance in every household, and it's hard to imagine life without it.Before the invention of the refrigerator, people had to rely on natural methods of preserving food, such as salting, smoking, and drying. These methods were time-consuming and often resulted in spoiled or rancid food. It was alsodifficult to store perishable foods like meat, dairy products, and fruits and vegetables for an extended period.In 1834, a young Scottish scientist named WilliamCullen made the first attempt to create artificial refrigeration. However, it wasn't until 1856 that anAmerican inventor, James Harrison, built the firstpractical refrigeration machine. The first commercial refrigeration unit was developed in the 1870s, and by the early 1900s, the refrigerator had become a common household appliance.The refrigerator works by removing heat from theinterior of the unit and expelling it to the outside. This is done by a process called refrigeration, which involves the compression and expansion of a refrigerant gas. The refrigerant gas absorbs heat from the interior of the unit, and then it is compressed, which raises its temperature. The hot gas is then cooled down, and it expands, which lowers its temperature. This process continues, and the heat is continuously removed from the interior of the unit.The refrigerator has many advantages. It allows us to store perishable foods for a more extended period, reducing waste and saving money. It also allows us to keep a variety of foods on hand, making meal planning and preparation more convenient. The refrigerator has also made it possible to transport food over long distances, which has led to theavailability of a wider variety of foods year-round.In conclusion, the invention of the refrigerator has had a significant impact on our lives. It has made it possible to store and preserve food more efficiently, reducing waste and saving money. The refrigerator has become an essential appliance in every household, and it's hard to imagine life without it.。

TheGreatestInventioninMyEyes
The Greatest Invention in My Eyes(winner)Ladies and Gentlemen:Good afternoon.When we ask others the question what is the greatest invention in their eyes, one thousand different persons may give one thousand different answers or even more. Many inventions are great in a way. Someone may name the invention of paper. Some others may name the invention of cars. But in my eyes, neither of them is great enough to be the greatest. Because with the invention of paper, we are losing our green froests and with the invention of cars, we have been losing our clean air. Many other inventions are similar in this sencse. They are just like doubleedged swords. We can never kill without being killed at the same time. Therefore, I, name the invention of bicycles. Bicycles can make us healthier and help us travel faster and faster. The most important thing: they are harmless to anything else.Haven't you noticed that our sky is becoming paler and paler? Haven't you noticed that fewer and fewer birds are singing outside your window? Or haven't you noticed that more and more people are dying of different kinds of cancers. Whenever I notice these phenomena, I can't help but wonder: Are we dying out like many other animals? Are we being annihilated from the earth? Or are we going into the night? Night, what a common word we use every day after the sun sets. But this nights is longer, even endless. Because we may not be able to see the next sunrise and the next rising Apolo will be greatly shocked to see a dead earth. Maybe, it's felt that today is in May. We have to be finghting again. But this time we are no longer fighting for such petty things as better housing and better salaries, but for the right to live, to exist. Ahead of us is not a single battle, it's a war. In this war, we don't have to pick up a gun to kill anyone. What we need to do is try to persuade as many people as possible to make full use of this greatest invention the world has ever seen. It sounds impossible to win the war. But should we win, we would not be celebrating a single May Day holiday in every May, we would be celebrating a bigger holiday, that's our Freedom Day. We would be free not from power, tyranny, persecution or discrimination, but from annhilation.Y ou may not agree with me, but please remember, the more we use the other invention, the more destructive we will be, while the more we use the greatest invention, the longer we can live.校级比赛的冠军讲稿。

Nowadays, the internet makes the impossible possible, we can communicate with foreigners online. The Internet also helps us know what happened on every corner of the world as quickly as we can. On the other hand, the internet makes our life and work convenient. In recent years, shopping online is very popular, we Just stay at home we can buy what we need online conveniently.

The result is that people may find they have less interest in the work and study and then get into a vicious circle. Another aspect is that lacking face-to-face communication brings emotional problems, the chatting and trade on the internet becomes less and less believable.In my eyes, the invention of the internet has changed the world, it is the greatest invention despite its disadvantages. It makes our society progress, makes our lives convenient, although there are still many problems, they will be solved in the near future.

The Greatest Invention in the Past Century
Teacher Lou
There are many amazing inventions in the last century. The most important invention, I think, is synthetic plastics.
In 1910, the synthetic plastics was first invented by an American chemistwho named Leo Baekeland.The plastic is phenolic resin. Eight years later, anAustriachemist called john invented urea resin. The plasticsis made ofurea resin have the properties oftransparent and light resistance compare with the first one. What’s more, they are nonflammable, lighter, cheaper, higher strength and hardness. The anther most important property is that plastics are anon-conducting materials.At a later time, different plastics that adapted different needs are invented one by one.
With those advantages, plastics are used every aspects in our life and produced different goods. Like the surface of electric wire, the shell of computers, the parts of all kinds of household appliances and the articles for daily use. For itself properties of stably, it can be used to packed foods. Without plastics, our daily life maybe become very inconvenient, and other materials which more heavily or light but expensive such as magnesium alloy have tobe used to product products. Even now, new materials haven’t be found to replaces it.
Because plastic are so stably, the nature environment unable to degradation it. The environment is serious polluted by plastics products that is optionally dropped by human. So, for our environment, plastic should be classification collection.。
