英语作文从自然中获取灵感的发明全文共3篇示例，供读者参考篇1Nature's Brilliant Designs: Inventions Inspired by the Natural WorldHave you ever noticed how many amazing things there are in nature? Plants, animals, even tiny insects and microbes have special abilities that are truly incredible. As a kid, I love exploring the outdoors and observing all the wonders of the natural world. What amazes me most is how humans have been able to look at nature and get inspiration to create awesome new inventions!Let me tell you about some of the coolest examples of inventions that were inspired by observing plants and creatures in their natural environments. Get ready to have your mind blown by nature's brilliance and human ingenuity!VelcroThis one is a classic. Can you believe Velcro, which is used to stick things together so easily, was inspired by burs getting stuck to a dog's fur? It's true! In the 1940s, a Swiss engineer named George de Mestral went for a hike and noticed burrs clingingtenaciously to his clothes and his dog's fur. When he looked closely under a microscope, he saw that the burrs had hundreds of tiny hooks that caught on anything looped, like fabric.De Mestral realized he could mimic thisnatural design to create two sides – one with tiny hooks and one with soft loops –that could stick together firmly but be pulled apart easily. And so Velcro was born! Isn't it awesome that such a simple observation in nature led to something we use constantly in our shoes, jackets, bags and more?Bullet TrainsJapan's incredible high-speed bullet trains are able to go over 200 miles per hour. But there was one big problem early on – whenever the trains came out of a tunnel, they created a loud "boom" sound from the built-up air pressure. This sound was so loud it could actually cause windows near the tracks to shatter!The engineers studying this issue got an ingenious idea from...the beak of a kingfisher bird. These sleek birds can smoothly dive from the air into bodies of water to catch fish with hardly a splash. Researchers realized the unique beak shape allows air and water to flow efficiently without creating turbulence.Mimicking the kingfisher's narrow beak, the front of the bullet trains were redesigned to be more aerodynamic. This small change completely solved the boom noise problem and allowed the trains to run much more efficiently at high speeds. Just amazing that a small bird could inspire something so useful for human transportation!Termite Mound Air-ConditioningHere's one that really blows my mind. The huge mounds built by termites, which can be taller than humans, do an incredible job of air-conditioning to keep the termite colonies inside at the perfect temperature. Using a remarkably smart design aided by constant wind movement, the mounds can stay around 87°F (30°C) inside even when outside temperatures vary from 35°F (2°C) all the way to 104°F (40°C).After studying termite mounds in Zimbabwe, researchers built an office building that copied the termites' ventilation design. This "Eastgate Centre" in Harare has no conventionalair-conditioning or heating, but stays regulated at an almost perfect temperature just through carefully designed ventilation. It uses 10% of the energy needed for a normal building its size!I think it's so cool that some of the best air-conditioning comes not from human engineering, but from observing theintricate mounds of tiny termites. Nature really can out-think us if we just pay close attention.Sharkskin SwimsuitsFor the last one, I've got to share something related to one of my biggest interests – swimming! You may have heard of the specialized swimsuits designed to reduce drag and increase speed called "sharkskin swimsuits." As the name suggests, these suits were inspired by the unique texture of sharkskin.While sharkskin feels smooth if you run your hand from the tail to the head, it actually has millions of tiny teeth-like scales that face backwards. This creates a surface that allows the shark to smoothly glide through the water. The rationale behind sharkskin swimsuits is that by having a textured surface mimicking these scale-like grooves, swimmers are able to cut through the water faster.After sharkskin swimsuits were approved for competition in 2008, they helped swimmers win numerous medals and set many new world records. All thanks to carefully observing the sleek skin of nature's most skillful swimming predator!Isn't it amazing how so many human inventions have been inspired by simply observing the natural world around us? Froma casual observation like burrs on a dog leading to Velcro, to studying microscopic details like sharkskin texture, nature is an endless source of brilliant designs and solutions.As a kid, I'm constantly in awe of the incredible abilities of plants and animals all around me. And I'm grateful that humans have shown the curiosity and ingenuity to take inspiration from nature to create so many useful inventions that make our lives better. Who knows how many more awesome innovations are waiting to be discovered by paying closer attention to the marvels of the natural world? I can't wait to see what we come up with next!篇2Nature's Awesome InventionsHave you ever looked around at all the amazing things in nature and thought "Wow, that's so cool! I wish we could make something like that." Well, lots of really smart inventors and engineers have done just that! By observing plants, animals, and the natural world, they've come up with ingenious ways to solve problems and create useful new inventions. Let me tell you about some of the awesome inventions that were inspired by nature.VelcroHave you ever gone on a hike and gotten burdock burrs stuck to your socks or clothes? Those little burrs can be really annoying, but a Swiss inventor named George de Mestral had a brilliant idea after taking a close look at them. In 1941, he went home and studied the burrs under a microscope. He noticed they had lots of tiny hooks that caught on loops in the fabric. De Mestral thought he could mimic this natural design to create a unique fastener. After lots of experimentation, he finally invented what we now call Velcro! The scratchy side has thousands of tiny hooks like the burrs, and the soft side is covered in soft loops for them to grab onto. Velcro is used on so many things today like shoes, jackets, bags, and even NASA spacesuits!Bullet Train NosesJapan's famous bullet trains are some of the fastest trains in the world. But do you know what helped inspire their super aerodynamic design? It was the beak of a kingfisher bird! Engineers noticed how sleek and streamlined a kingfisher's beak is as it dives into water to catch fish. This allows the bird to move very quickly through the water with minimal resistance. The engineers used similar aerodynamic principles when designing the nose cones for the bullet trains. The cones are shaped justlike the narrow beak of a kingfisher, allowing the trains to cut through the air efficiently at incredibly high speeds.Gecko TapeGeckos are those cool little lizards that can climb up smooth walls and hang upside down from ceilings. Pretty neat, right? Well, it's all thanks to millions of tiny hairs on their toes that allow them to stick using molecular attraction. In 2012, scientists and engineers were able to recreate this incredible gripping ability to create Gecko Tape. The tape has synthetic hairs that interact with surfaces the same way a gecko's toes do through van der Waals forces. Gecko Tape can hold up to 700 pounds per square inch! It could be used to make climbing robots, help space vehicles grab onto things, or even let you walk on walls like Spider-Man. As one of the scientists said, "Nature isn't a bad model to follow."Underwater AdhesivesHave you ever tried to stick two things together under water? It's basically impossible because most glues don't work when they get wet. But certain sea creatures like mussels and barnacles figured out how to solidly attach themselves to rocks, ships, and other surfaces in the ocean. Scientists took a close look at the proteins in mussel threads to try and mimic that natural adhesiveability. They were able to reverse engineer a synthetic underwater adhesive that can be used to bond materials together in wet environments. Potential uses range from repairing boat hulls and submarines to delivering drugs or medical sensors inside the human body. Once again, nature provided the perfect model for human innovation.Self-Cleaning MaterialsHave you noticed that it's pretty hard to keep windows and other glass surfaces clean for very long? Dirt, dust, and water spots accumulate so quickly. Well, inventors took a cue from leaves and came up with incredibly self-cleaning glass! Many plant leaves have a micro-texured, super hydrophobic(water-repelling) surface that allows rain and dirt to easily wash away. By etching microscopic patterns into the surface of glass, scientists created a product that mimics that self-cleaning property of nature. When water hits the specialtexture, it forms spheres that easily pick up dust and dirt and roll right off. These self-cleaning windows can be found on many buildings today, and the technology has applications for other products too like self-cleaning exterior paint and fabric.Nature is awesome, isn't it? It has taken millions of years for plants and animals to evolve all sorts of unique abilities and traitsto survive and thrive. But instead of just marveling at them, humans have found incredibly clever ways to take inspiration from nature's designs. Who knows what other brilliantbio-inspired inventions scientists and engineers will come up with next? By observing and learning from the natural world around us, the possibilities are endless for solving problems and creating innovative new technologies. If I were you, I'd keep my eyes open for more of nature's marvels - the next great human invention might just be growing or crawling right in front of you!篇3Nature's Wonders and Human InventionsHave you ever looked around at all the amazing things in nature and thought "Wow, how did that happen?" Well, a lot of very smart people have done the same thing. By studying plants, animals, and the natural world, they've gotten ideas for incredible new inventions that make our lives better. Nature is honestly the best teacher and inspiration!One example is airplanes. You might think "How is a big metal tube anything like nature?" But the Wright brothers, who invented the first successful airplane, were inspired by observations of birds. They noticed how birds angled their wingsto steer and propelled themselves by flapping. The Wright brothers then applied similar principles of aerodynamics to build their flying machine. Wild, right?Speaking of flying, let me tell you about the awesome invention of Velcro. In 1941, a Swiss engineer named George de Mestral went on a hiking trip and got covered in burrs that stuck to his clothes and his dog's fur. Rather than just grumbling about it, de Mestral was curious. He looked at the burrs under a microscope and saw they had tiny hooks that caught on loops in the fabric. This gave him the brilliant idea to invent Velcro - two strips of fabric with hooks and loops that stick together but can be pulled apart. Thank you, burrs!There are tons of medical inventions inspired by nature too. The ancient Greeks observed willow tree bark relieving pain and fever. Much later, scientists were able to extract salicylic acid from willow bark, which led to developing aspirin and other drugs. Morphine, an important painkiller, came from the opium poppy plant. Even the idea of using leeches in medicine was taken from how they naturally attach and help drain blood.Natural creatures have been a huge inspiration for robotics. Robots have been modeled after insects, snakes, fish, and even humans to make them better at walking, swimming, climbing,and other complex movements. Scientists studied insects like cockroaches that are able to squeeze through tiny spaces and keep going even when flipped over. Using what they learned, they built robots that can do search and rescue tasks in areas too small or dangerous for humans.Sometimes nature's inspiration is right there in the name of an invention. The videocam "camcorder" got its name by combining "camera" and "recorder," just like "camouflage" comes from the French for "to disguise." Both words refer to animals' natural ability to blend into their surroundings. People copied this to develop better military disguises and eventually, portable video cameras.We can't forget about giant nautical inventions like ships and submarines, which were inspired by floating and swimming creatures like ducks, fish, and whales. Steel ship hulls got the idea of being streamlined from observing fish. And the first primitive submarines were literally just underwater rowboats sealed with animal skins. Thank you, fish and furry friends!Even some of the coolest fictional inventions were inspired by biology. Everyone's heard of Spider-Man, right? Hisweb-shooters were straight-up copied from how real spiders can shoot out sticky webs. Comic book writers were so impressed byspider silk that they gave Spider-Man the same ability, but powered by fun gadgets instead of being "naturally" produced.Some nature inspirations are just mind-blowing. You know those colorful stickers and decorations that seem to shimmer with rainbows moving across them? Their inventor was inspired by the iridescent colors found in things like butterfly wings, pearls, and soap bubbles. It happens when light bounces off tiny grooves in just the right way, creating those spectacular shimmery effects.Of course, nature doesn't directly hand us ready-made inventions - it takes super creative and hard-working people to turn those inspirations into reality. But we would be a lot worse off without the natural world to spark ideas and point us in the right direction.Even kids like you can get in on this. Maybe you'll notice how spiderwebs are structured in a certain pattern that's crazy strong for its size. Or how chameleons can change color by using fancy cells to shift the pigments in their skin. Or you'll be intrigued by the stickiness of gecko feet that allows them to climb walls. Who knows - observations like those could lead to new discoveries and groundbreaking inventions someday!At the very least, I hope this has given you a newfound appreciation for the wonders of nature and all the ways it has helped human creativity and ingenuity. Next time you're walking outside, I challenge you to keep your eyes peeled for plants, animals, or anything else that makes you think "Whoa, how does that work?" You might just be looking at the inspiration for the world's next big invention!。
关于滑板的英语句子1. 介绍滑板的英文文章Skiboarding is a winter sport which combines elements of skating, snowboarding, and skiing. Skiboards are generally 80-120 centimeters long, symmetrical, twin tipped, and wider than traditional skis. In addition, they generally have non-release bindings, very similar to snowboard hard-boot bindings. However, skiboards are now on the market which feature ski-like releasable bindings. The sport is often referred to (especially in the UK) as snowblading or skiblading, however, "Snowblades" are a trademark of Salomon.The first prototype of the modern skiboard was the Atomic Glider (later renamed the Figl), a 63.5 centimeter bindingless ski designed in 1982 to fit into a hiker's backpack and sold primarily in Colorado. Around 1990, Austrian company Kneissel introduced the BigFoot, a 65 centimeter, foam-injected ski with a binding system. Some consider the BigFoot to be the first mass-produced skiboard. Next came the MicroSki, created by Kent Keiswieller in 1992.From 1993-1996, the first products actually referred to as skiboards were manufactured by several pioneer companies, including Canon, Line, GrooveUSA, Klimax, and Powder Company.In 1997, French ski company Salomon released their version of skiboards, called Snowblades, in response to skiboarding's growing popularity. Soon many larger ski companies such began to produce skiboards.Skiboarding was replaced with skiing in the X Games, a hard hit to the United Skiboard Series (USS). Professional skiboarders no longer had a forum to compete, and several professional skiboarders including Mike Nick, Iannick B., and Nicky Adams switched to freestyle skiing. The lack of aprofessional circuit caused skiboarding to drop in popularity around 2001.Since then, skiboarding has been growing a steady following. Some elements of skiboarding are easier to learn than skiing, so many people with little or no experience in snow sports can use it as an easy way to get down the slopes. Skiboards can also be used as a tool to learn skiing, or as a change of pace for advanced skiers. The short length and sidecut of skiboards makes them easier to turn than traditional skis, but their short length also makes it more important to have a centered stance. Because of the shorter length, skiboarding is hard to perfect where longer skis give an advantage, such as when performing aerial maneuvers, skiing through soft snow or powder, and generally more aggressive skiing.In 2004, Bentfilms released White Dwarf, a skiboarding video highlighting the technical possibilities of skiboarding, separating it from skiing, and showcasing the talents of many new riders.2007 marked a landmark in the advancement of skiboarding, as riders from around the world came together in Predeal, Romania for the first ever Skiboard World Cup. Three freestyle events were held (Rail Jam, Big Air and Slopestyle) as well as three racing events (Skiboard Cross, Fakie Downhill and Chinese Downhill). The World Skiboard Association was the main organizer of the event.。
