台球来自法国的英语作文Title: The Origins and Evolution of Billiards。
Billiards, a game enjoyed by millions worldwide, traces its origins back to France in the 15th century. It's a game that has evolved significantly over the centuries, captivating players with its blend of strategy, skill, and precision. In this essay, we delve into the rich history and evolution of billiards, exploring its origins, development, and enduring appeal.The roots of billiards can be traced to the 15th century, where it emerged as a popular pastime among French nobility. Initially known as "billiard" (derived from the French word "bille," meaning ball), the game was played using wooden sticks called "maces" to strike balls on a grass-covered lawn. Over time, the game transitioned indoors, evolving into what we now recognize as modern billiards.One of the earliest recorded forms of indoor billiards was known as "carom billiards," where players aimed to strike their cue ball to hit both the opponent's cue ball and a third ball, known as the "object ball," without potting any balls. This early form of billiards laid the foundation for the development of various cue sports, including pool and snooker.During the 19th century, billiards experienced a surge in popularity across Europe and North America. The invention of the leather-tipped cue by French scientist François Mingaud in 1807 revolutionized the game, allowing players to apply spin and control to their shots with greater precision. This innovation led to the rise of new cue sports variations, such as English billiards and American four-ball billiards.In the latter half of the 19th century, billiards underwent further evolution with the introduction of pool tables featuring pockets. This innovation gave birth to the game of "pool," where players sought to pot specific balls into designated pockets using a cue stick. Pool quicklybecame a favorite pastime in bars, clubs, and recreational venues, contributing to the proliferation of billiard halls across the globe.Meanwhile, in the British colonies, another variant of billiards was gaining popularity: snooker. Developed in the late 19th century by British Army officers stationed in India, snooker combined elements of pool and pyramid pool, featuring colored balls with varying point values. The game's intricate rules and strategic gameplay appealed to a wide audience, leading to its widespread adoption and eventual establishment as a professional sport.Throughout the 20th century, billiards continued to evolve, with innovations in equipment, rules, and tournament formats shaping the game's trajectory. The establishment of governing bodies, such as the World Pool-Billiard Association (WPA) and the World Professional Billiards and Snooker Association (WPBSA), further standardized the sport and facilitated its global growth.In recent decades, technological advancements havetransformed the landscape of billiards, with televised tournaments, online gaming platforms, and virtual reality simulations expanding the reach and accessibility of the sport. Despite these modern adaptations, the essence of billiards remains rooted in its rich history and tradition, attracting players of all ages and skill levels to participate in the timeless pursuit of cue mastery.In conclusion, billiards has come a long way since its humble origins in 15th-century France. From the grassy lawns of aristocratic estates to the dimly lit halls of modern billiard clubs, the game has captivated generations with its blend of skill, strategy, and camaraderie. As we look to the future, one thing remains certain: billiards will continue to endure as a beloved pastime, uniting players from diverse backgrounds in the shared pursuit of cue mastery and excellence.。

Its massive circular frame seemed to pierce the very clouds above, with each gondola gleaming invitingly in the golden rays of the afternoon sun. A mischievous grin spread across Xiao Ming's face as he turned to me, his eyes sparkling with enthusiasm."Xiao Lan, let's play the Ferris Wheel game!" he exclaimed, practically bouncing on the balls of his feet. The Ferris Wheel game was a beloved tradition among our classmates, a rite of passage that tested one's courage and determination.The rules were simple: secure a spot on the Ferris wheel and remain seated until the very last revolution, enduring the dizzying heights and heart-pounding suspense. The first person to abandon their seat would be deemed the loser, forced to face the ridicule of their peers. Despite the seemingly harmless nature of the game, its psychological toll was not to be underestimated.With a mix of trepidation and excitement coursing through my veins, I nodded in agreement, determined not to back down from Xiao Ming's challenge. We hurried towards the ticket booth, eagerly exchanging our hard-earned coins for a chance to prove our mettle.As we approached the loading area, the sheer magnitude of the Ferris wheel became even more apparent, its towering presence commanding respect and awe. Xiao Ming flashed me a confident smirk, clearly relishing the opportunity to assert his bravery.We settled into our respective gondolas, the sturdy metal bars providing a sense of security, yet doing little to quell the butterflies dancing in my stomach. The ride operator, a wizened old man with a mischievous twinkle in his eye, wished us luck before setting the wheel in motion.Initially, the ascent was gentle and serene, the gondolas swaying ever so slightly as we rose higher and higher. The park below transformed into a vibrant tapestry of colors, with the distant sounds of laughter and music fading into a soothing hum. For a brief moment, it felt as though we were suspended in a realm of tranquility, soaring above the worries of the world.However, our peaceful reverie was short-lived as the wheel picked up speed, the centrifugal force pressing us firmly into our seats. Xiao Ming's earlier bravado seemed to waver slightly, his knuckles turning white as he gripped the safety bar with renewed intensity.With each revolution, the sensation grew more intense, the ground below becoming a dizzying blur. The wind whipped through our hair, carrying the scent of popcorn and sugary treats from the concession stands below. Xiao Ming's face contorted into a grimace, his lips pressed into a thin line as he fought against the urge to surrender.As for me, a peculiar sense of exhilaration washed over me, fueled by the adrenaline coursing through my veins. The world seemed to spin around us, challenging our perception of reality and testing the limits of our fortitude.Round after round, we clung to our seats, determined to outlast one another in this battle of wills. Xiao Ming's resilience was admirable, but I could sense his resolve beginning to falter. Beads of sweat trickled down his forehead, his eyes squeezed shut as he tried to maintain his composure.Finally, after what felt like an eternity, the ride began to slow, the centrifugal force gradually subsiding. Xiao Ming's eyesflickered open, a mixture of relief and disappointment etched across his face.As our gondolas came to a stop, we stumbled out onto solid ground, our legs momentarily unsteady from the dizzying experience. Xiao Ming shot me a rueful grin, acknowledging my victory in our unspoken contest."Well played, Xiao Lan," he conceded, his voice tinged with a hint of admiration. "I thought for sure you were going to give up before me."I couldn't help but laugh, the residual adrenaline still coursing through my veins. "Never underestimate my determination, Xiao Ming," I teased, nudging him playfully.As we made our way towards the exit, exchanging stories and reliving the thrilling moments of our Ferris wheel adventure, I couldn't help but feel a sense of accomplishment. Not only had I conquered my fears, but I had also solidified my friendship with Xiao Ming through our shared experience.The Ferris Wheel game had become more than just a test of courage; it was a bond that tied us together, a reminder of the unbreakable spirit that defined our childhood. And as we ventured forth into the vibrant world of the amusement park,ready to tackle the next thrilling ride or game, I knew that our memories of that day would forever be etched into our hearts, a testament to the enduring power of friendship and the ability to conquer our fears together.篇2The Ferris Wheel AdventureIt was a warm, sunny Saturday afternoon and I was feeling bored at home. My best friend Xiao Lan called me up and suggested we head down to the annual carnival that had arrived in town. "They've got all the classic games and rides," she told me excitedly. "We have to go check it out!"I didn't need much convincing. We quickly made plans to meet up at the carnival grounds in an hour. As soon as I arrived, I spotted Xiao Lan waving at me from beside the ticket booth. She came running over, her green sundress flapping in the breeze."Finally! I was worried you wouldn't show up," she teased, punching me lightly on the arm. "Come on, I already got us unlimited ride wristbands."Xiao Lan led the way as we entered the carnival, and I was immediately overwhelmed by the sights, sounds, and smells. The air was thick with the scent of hot dogs, funnel cakes, andcandied nuts. Kids ran between the different game booths, carrying over-sized stuffed animals nearly as big as they were. The shrieks and laughter from the roller coaster riders filled the air."Where should we go first?" I asked, turning in a circle slowly to take it all in. So many choices - the haunted house, the bumper cars, the spinning teacups."Let's start with the ferris wheel," Xiao Lan suggested, pointing to the towering ride that rose high above everything else. "That way we can get a view of the whole place and plan our attack."We joined the queue for the ferris wheel, somehow ending up behind a family with three rambunctious young boys. As we inched ahead in line, the boys took turns stating dramatic facts about ferris wheels that they had likely learned in school that week."Did you know that ferris wheels were invented at the 1893 World's Fair in Chicago?" one piped up."Yeah, and the original one was 264 feet tall!" his brother added."That's nothing," the third one scoffed. "The current tallest ferris wheel is 689 feet high and is located in Las Vegas!"Xiao Lan and I exchanged amused looks at their encyclopedic ferris wheel knowledge. We made idle chitchat to pass the time, discussing our plans for the summer and whether we should repaint our secret hideout tree house.Finally, it was our turn to board the ferris wheel carriage. An apathetic-looking teenage ride operator ushered us in and pulled the safety bar across our laps with a resounding clank. With a lurch, the wheel began its stately rotation, lifting us up and up until we could see for miles in every direction.As we rose higher, Xiao Lan pointed out the different landmarks visible from our vantage point - the tall office buildings downtown, the river winding through the city, and the mountains rising up in the distance. I noticed a few other carnival rides that looked entertaining - the double-looping rollercoaster that left your stomach on the ground and the free-fall tower that dropped you from dizzying heights."So what's the plan?" I asked Xiao Lan as the wheel reached its highest point and started its downward rotation. "What ride should we hit next?"My daring friend didn't hesitate. "I think we should do the Double Demolition Death Drop," she said with a wicked grin.I blanched. "You mean that free-fall tower? No way, I don't have a death wish!"Xiao Lan just laughed at my reaction. We began eagerly debating the merits and perils of each terrifying ride, time flying by as we slowly circled towards the ground again.With a final rumbling jolt, our carriage arrived back at the boarding platform and the operator opened the safety bar. "Watch your step," he said in a bored monotone as we carefully disembarked.We had just set foot on solid ground when a deafening clap of thunder made us both jump. Xiao Lan and I looked up at the sky in dismay as the first heavy raindrops began to fall, quickly segueing into a torrential downpour."Seriously?" Xiao Lan groaned, shaking her head. She grabbed my hand and started running, pulling me along behind her towards the nearest shelter - the entrance pavilion for the ferris wheel ride we had just disembarked.We huddled underneath the minimal covering it offered, quietly watching as the midway turned into a ghost town withinminutes. The vendors hastily covered their game booths and food stands while the few remaining hardy souls still braved the rides with the protection of flimsy ponchos and umbrellas.Beside me, Xiao Lan shivered slightly as the rain kept coming down in sheets. I felt a pang of guilt for not grabbing jackets before we came out. But then she looked over at me with sparkling eyes and I knew she was nowhere near ready to call it a day."You know what this means, right?" she asked with a mischievous grin spreading across her face. "An empty carnival is a perfect opportunity..."I instantly knew what she was getting at and laughed. Despite the downpour, this adventure was only just beginning. Hand in hand, we took off running into the deserted midway, ready to take on the abandoned rides and make the most of this unexpected situation.Some kids might view an empty, rain-soaked carnival as a dreary disappointment. But not us - we saw it as a wide open playground just waiting to be explored. Xiao Lan and I hurried from ride to ride, relishing the freedom of having everything to ourselves.The haunted house staff had already fled, leaving the interior lights on and the chilling narration still playing on a loop as we crept through the dark corridors, laughing at the cheesyjump-scares. We gleefully ran amok on the spinning teacup ride, whirling around and around until we could barely stand up straight when we disembarked.Probably the most fun was riding the roller coaster over and over again without having to wait in line even once. We rode it forwards, backwards, and even managed to sneak into the operator's booth to start and stop the coaster whenever we felt like it. By the time we had our fill, my clothes were drenched and streaks of purple face paint from an early ride on the spinning rides covered both our faces.Eventually, as quickly as the storm had rolled in, the rain finally let up and stopped. We emerged from our soaked carnival playground, squinting against the bright rays of late afternoon sunshine.In the distance, we could see the first staff members returning to begin the painstaking process of re-opening the rides and stands. Xiao Lan and I shared a look of mischievous triumph, already knowing this day would become one of those priceless memories we'd reminisce about for years to come.Dripping wet but beaming, we set off to find a spot to grab a celebratory ice cream and some much-needed dry clothes. The deserted carnival had been the best unplanned adventure either of us could have asked for. Just another example of how a little rain and an open mind could turn an ordinary day into something extraordinary when you had a partner in crime as awesome as my best friend Xiao Lan.篇3A Thrilling Ride on the Ferris WheelIt was a beautiful sunny day and the excitement was palpable in the air as my best friend Xiao Lan and I made our way to the annual school carnival. We had been looking forward to this day for weeks, saving up our allowance money to splurge on games, rides, and all the delicious snacks.As we approached the carnival grounds, the unmistakable aroma of cotton candy and funnel cakes wafted through the air, instantly making my mouth water. The kaleidoscope of bright colors from the various game booths and rides was dazzling to the eyes. But one ride towered above them all - the gigantic Ferris wheel that seemed to stretch up and touch the clouds."Oh Xiao Ming, we simply must go on the Ferris wheel!" Xiao Lan exclaimed, tugging at my sleeve eagerly. I had to admit, the thought of soaring high above the carnival did send a tremor of excitement through me.We made a beeline for the ride, weaving through the throngs of people until we reached the entrance. The line was quite long, but we didn't mind the wait as it allowed us to study the impressive ride up close. Each gondola was brilliantly painted and adorned with dazzling lights that flickered mesmerizingly.Finally, after what felt like an eternity, it was our turn to board. The attendant ushered us into one of the gondolas and securely fastened the safety bar across our laps. As the wheel jerked into motion, Xiao Lan and I exchanged a giddy look, gripping each other's hands tightly in anticipation.Slowly but surely, our gondola began its ascent towards the sky. With each revolution, the carnival below seemed to grow smaller and smaller until the people began to look like mere ants scurrying about. The higher we went, the more I could feel the gentle swaying of the gondola, almost like we were floating on clouds."Look out there Xiao Ming!" Xiao Lan gasped, pointing towards the horizon. "You can see the entire city from up here!"She was absolutely right. Stretched out before us was an endless vista of skyscrapers, parks, and winding roads. The sight was so breathtaking that I found myself momentarily rendered speechless, awestruck by the sheer beauty.As our gondola reached the very top of the arc, it paused for a moment, suspending us at the dizzying height. The world below looked so tiny and distant from this vantage point that it felt almost surreal. Xiao Lan and I sat in respectful silence, simply taking in the magnificent panoramic view.All too soon, our ride began its descent back towards the ground. Although my stomach did a few somersaults as we drifted back down, I couldn't wipe the euphoric smile off my face. We had just experienced something so exhilarating and wondrous."Wasn't that simply marvelous?" Xiao Lan sighed wistfully as we disembarked onto solid ground once more. "I wish we could stay up there all day and just soak in those incredible views."I had to agree wholeheartedly. While the Ferris wheel ride had been over in a matter of minutes, the memories we made would be etched into our minds forever. It was a soaring experience that filled us with breathless amazement and childlike wonder.As we meandered away from the ride, grabbing clutching souvenirstrinkets and snapping photos to commemorate the day, I knew that this was just the beginning of many more adventures to come at the carnival with my dearest friend. Just like how the Ferris wheel keeps going round and round, our fun and excitement was an endless loop. And I couldn't wait to see what other thrills awaited us.。

An Insider’s View of the Myths and Truths of the 3-D Printing‘Phenomenon’BY CARL BASS 05.28.13 | 6:30 AM | PERMALINKA 3-D printed table … with holes and all.Photo: rosemarybeetle / FlickrFrom a major VC firm’s recent $30 million investment in the industrial-grade 3-D printing space to the news that Staples will become the first major U.S. retailer to sell consumer-friendly 3-D printers, it’s clear that 3-D printing has reached its inflection point.And perhaps its hype point, too.The technology is decades old, but now there’s an ecosystem in place (which includes my own company) that moves it beyond the maker edges to mainstream center. So now more than ever I’m asked for an insider’s view on the hype vs. realities of 3-D printing —and where it’s going.3-D printing won’t replace other manufacturing technology3-D printing is indeed an important fabrication technology, because it has the marvelous ability to make anything regardless of the complexity of the form. Other fabrication techniques, honed over decades of industrialization, struggle with geometric complexity — where 3-D printers can print either the most intricate shapes or simplest cube with equal ease.THE FACT IS THAT 3-D PRINTING IS REALLY, STILL, AN IMMATURE TECHNOLOGY.Never before have we had a technology where we can so freely translate our ideas into a tangible object with little regard to the machinery or skills available. Yet just as the microwave didn’t replace all other forms of cooking as initially predicted, 3-D printing will not replace other manufacturing technologies let alone industrial-scale ones for a variety of reasons. It will complement them.The fact is that 3-D printing is really, still, an immature technology. We’ve built a magical aura around it — sci-fi style replicator! — but as soon as anyone actually uses a 3-D printer for any period of time, they immediately wish for faster build times, higher quality prints, larger build envelopes, better and cheaper materials … and so on.We need a different kind of Moore’s-like Law for 3-D printingWhile the hype paints visions of limitless replication — lost components, shoes, body parts, musical instruments, even guns—here’s a key fact: Where 3-D printing may be unfettered by complexity, it is constrained by volume.Everything from cost and time to amount of material increases exponentially: specifically, to the third power.So if we want something twice as big, it will cost 8 times as much and take 8 times as long to print. If we want something three times as big, it will cost about 27 times more and takes 27 times longer to print. And so on.The 3-D printing ecosystem is changingThe limitations introduced by “the 3rd power law of 3-D printing” — as well as the freedom of scale introduced by the unfettered complexity — should bookend any discussion of where 3-D printing is going.But everything else in between these two immutable facts is constantly changing. That includes the quality and speed of 3-D printing as well as the vibrant collection of people and companies working to overcome the current limitations and broaden use of the technology.The most common 3-D printing today is smaller-than-a-breadbox printing of plastic parts on machines ranging from open-source printers like RepRap to off-the-shelf printers like 3D Systems’ Cube (the one being carried by Staples). Then there are low-cost commercial printers like MakerBot and more expensive industrial versions made by companies like Stratasys and EOS. [For more specific numbers and data about the size, share, and growth of the market here, see the recent annual report by Wohlers Associates, which has been releasing it for 18 years.]The ecosystem isn’t just about the printers, however. 3-D printing is part of the accelerating software-controlled manufacturing trend which is making not just 3-D printers — but laser cutters, mills, lathes, routers, and industrial robots —increasingly powerful, affordable, approachable … andtherefore accessible to lay users. Software is democratizing this space just as the PC democratized computing.3-D printing needs better business modelsThe range of 3-D printable materials and scale of output has broadened considerably even as the plastic formulations of current materials continue to improve. Large industrial printers can now print metal, rubber, and ceramics in addition to plastic.However, many commenters focus so much on the limitations of printed materials, that they tend to overlook something much more important:the cost.In the average life of a typical 3-D printer, yards — even miles — of material (which are really just spools of plastic) can be used. Many manufacturers have therefore adopted a razor-razorblade model, or in this case: an inkjet cartridge-like business model for 3-D printing. There’s really very little difference between the material fed into the 3-D printer and the raw commodity, yet the cost to consumers can be up to 100 times higher. So I think this aspect is ripe for new business models that would better expand the use of 3-D printing technology and viability of the marketplace.These are the important research directionsWith so much buzz around every latest announcement in the 3-D printing space, it’s hard to tell what’s commonplace and what’s really interesting to pay attention to. Because constant improvements are happening in everything and especially in what you can print — whether replacement part or novel design, inert or organic material, at scales from the microscopic to a house, on earth or in space.THE 3RD POWER LAW OF 3-D PRINTING: EVERYTHING FROM COST AND TIME TO AMOUNT OF MATERIAL INCREASES TO THE THIRD POWER.I think two important areas to watch here are printing electronics— i.e., not just objects but logic and function — and the burgeoning fieldof bioprinting. The latter represents some of the most exciting work employing 3-D printers. For example, Dr. Anthony Atala of Wake Forest University has pioneered work that includes the successful printing and implantation of human urethras. San Diego-based Organovo prints functional human tissue that can be used for medical research and therapeutic applications. And companies like Craig Venter’s as well as Cambrian Genomics (which I have a small personal investment in) are printing DNA —yes, DNA! — one base pair at a time.Another important direction in the 3-D printing landscape involves the shift to architectural-scale 3-D printing. Examples include the work of RonRael at U.C. Berkeley, who has been working with new, low-cost organic materials and the work of Boris Behrokh Khoshnevis at the University of Southern California who has been experimenting with 3-D printing full-size buildings.The European Space Agency and Foster + Partners have teamed up to design a moonbase structure 3-D printed with Monolite UK’s D-Shape, though the beauty of their concept is that it would draw entirely on materials found onthe moon. This is important since it helps push the materials limitations of 3-D printing from what is supplied to what is found. And someone out there has already hacked a 3-D printer to use only waste materials — imagine the possibilities of using 3-D printing for true recycling and reuse.The next shift is from prototypingto limited production3-D printing and other technologies in the software-controlled manufacturing trend fundamentally rewrite the rules of mass production. No longer do we need to produce things in very large quantities to enjoy low cost and high quality; we can get very high quality products in small lots at a reasonable cost.There is a shift looming where 3-D printing can be useful for more than just rapid prototyping of small plastic parts and for small-batchproduction. However, I don’t expect to see 3-D printing replace very inexpensive production methods.NOTE THAT COST-PLUS BUSINESS MODELS ARE VERY VULNERABLE TO DISRUPTION —IT’S THE EQUIVALENT OF HAVING A ONE-TRICK PONY IN THE RACE.Think about the Kinko’s model, which didn’t replace desktop printers or production-scale printing houses — but still played an important role in the reproduction ecosystem. With 3-D printing, companies like Shapeways round out the ecosystem of printer hardware and software-controlled manufacturing by providing both services for 3-D printing and a marketplace of designs. And then there are also design repositories, like Thingiverse, and Instructables (owned by Autodesk).Note however that fee-based, cost-plus/ time-and-materials business models are very vulnerable to disruption —it’s the equivalent of having a one-trickpony in the race. The advantage there, then, isn’t in be ing a first mover but in having a rich and thriving community —that’s the key differentiator in what can easily become a crowded space.Instead of a mass-manufacturing marketplace where everything is made the same way, I expect the “production” trajectory for 3-D printing to start with low-volume, high-value objects like prosthetic devices or bespoke itemslike jewelry. Most 3-D printing will be personal and custom, similar to the way we use our inkjet printers today. Just as rip-mix-burn became the anthem for digital music, we are starting to do the same thing for the physical world with capture-modify-print (or download-modify-print) using only the cameras on our cellphones to inform computer vision algorithms.3-D printing won’t bring manufacturing back to the United StatesSo will this capability really bring manufacturing back to the U.S. and other developed countries?Yes and no. It will enable domestic manufacturing, but not the same kind, and it probably will not bring back the jobs that have been lost. The product companies of the future will have design, engineering, and manufacturing more tightly integrated together — rapid prototyping and the ability to manufacture small runs will be crucial to their success. This means the jobs of the future will continue to be higher skilled, and that the skills of future craftspeople will be as much digital as they are analog.Perhaps the only way to truly understand the crucial role computers are playing in the next generation of manufacturing is, ironically, by omitting the digital. There’s a delightful 3-D printing device on Kickstarter called the3Doodler — a 3-D printer without the computer — which has raised more than $2M. You can hold it in your hand and “draw” in the air, essentially piling molten plastic on top of itself. But it’s like dripping wet sand to build castles in the air. So while this revolution may appear to be all about hardware, it’s impossible without the microprocessors and the software.Editor: Sonal Chokshi @smc90听内行人讲解3D打印神话译者:nancyzo原文作者:BY CARL BASS, 05.28.13从风投公司在工业3D打印领域投资三千万美元到有消息称史泰博公司将会成为全美首家消费型3D打印机零售商之后,毫无疑问,3D打印技术有了峰回路转的改变。

Oil Drilling & Production Technology, 2022,44(6): 733-739.Abstract: The buried hill metamorphic rock reservoir of the Jilantai oilfield features shallow burial (400−650 m), high heterogeneity, and the development of high-angle natural fractures and the bottom water system. The fracturing reservoir stimulation suffers from high difficulties in cracking strata, proneness to connection with the bottom water, and blindness for sweet spots. The analysis of the characteristics of the metamorphic rock reservoir combined with the gained fracturing experience showed that the optimal height of water avoidance for water production control is 100−120 m. The bridge plug-perforating integrated technology with the 25 ℃ low-temperature soluble bridge plug was applied to facilitate high-pump-rate large-scale multi-stage fracturing. The perforating azimuth was optimized to avoid perforating the upper 120° range and lower sand production risks. The water-soluble temporary plugging agent was adopted for inter-layer/intra-layer temporary plugging, which led to a pressure rise of 5−8 MPa. The geological-engineering dual sweet spots were identified via long-distance sonic imaging, and the reservoir stimulation model featuring fewer stages and more clusters was formed. The presented fracturing technology was applied to 13 wells of the buried hill metamorphic rock reservoir in the Jihua-1 block, including 74 fracturing stages and 361 perforation clusters. Compared with the testing wells in early 2020, these wells presented the average fracturing stage reduction by 2 stages/well and the growth of initial post-第一作者: 朱瑞彬(1981-),2006年毕业于西南石油大学石油工程专业,华北油田公司党委委员,总工程师,现从事油气田开发研究及管理工作。

如果你去观光你会乘坐什么交通工具英语作文全文共3篇示例,供读者参考篇1If You Were Going Sightseeing, What Transportation Would You Take?Traveling and exploring new places is one of the most enriching experiences in life. When you're out sightseeing, the journey itself can be just as memorable as the destinations. The mode of transportation you choose can greatly impact your overall travel experience, convenience, and even budget. As a student, I've had the opportunity to venture out and discover different cities, both near and far, and I've learned that the right transportation choice can make or break a sightseeing adventure.For shorter trips or city explorations, my go-to option is often good old walking. There's something truly special about experiencing a place on foot, taking in the sights, sounds, and smells at a slower pace. It allows you to immerse yourself in the local culture, stumble upon hidden gems, and appreciate the little details that might be missed when whizzing by in a vehicle.Plus, it's an excellent way to stay active and burn off all those delicious local treats you'll inevitably indulge in.However, walking isn't always practical, especially when covering larger distances or dealing with luggage. In these cases, public transportation can be a lifesaver. Buses, trains, and subways are not only budget-friendly but also offer a unique glimpse into the daily lives of locals. There's something incredibly humbling about squeezing onto a crowded metro car, surrounded by people from all walks of life, each with their own stories and destinations.One of my fondest memories is navigating the intricate subway systems of major cities like London and Tokyo. The thrill of deciphering the color-coded maps, the rhythmic rumble of the trains, and the occasional disorientation when emerging from underground stations – it all added to the adventure. And let's not forget the convenience of hopping on and off at various stops, allowing you to explore multiple neighborhoods in a single day.For longer journeys or when traveling with a group, renting a car can be a liberating experience. The freedom to set your own schedule, take spontaneous detours, and blast your favorite road trip playlist is unmatched. Plus, having your own wheels meansyou can venture off the beaten path and discover those hidden gems that are often overlooked by tourists relying solely on public transportation.One of my most memorable road trips was driving along the picturesque coastline of California's Pacific Coast Highway. The winding roads, breathtaking ocean views, and the ability to stop whenever a charming seaside town caught our eye made the journey just as memorable as the destinations themselves.Of course, renting a car also comes with its challenges, such as navigating unfamiliar roads, finding parking, and dealing with the inevitable traffic jams. But for me, the sense of independence and flexibility more than makes up for these minor inconveniences.For those seeking a more adventurous and environmentally-friendly mode of transportation, cycling is an excellent option. Not only is it a great way to stay active and reduce your carbon footprint, but it also allows you to truly immerse yourself in the local surroundings at a leisurely pace. Imagine pedaling through quaint villages, winding country roads, or even urban landscapes, taking in the sights, sounds, and smells that would be missed from the confines of a car or bus.One of my most cherished cycling experiences was exploring the stunning countryside of Tuscany, Italy. The gentle hills, vineyards, and medieval towns seemed frozen in time, and the freedom to stop and picnic under an olive tree or explore a hidden chapel added to the enchantment of the journey.Of course, cycling isn't without its challenges, especially when navigating busy city streets or steep terrain. But with proper planning, appropriate gear, and a sense of adventure, it can be an incredibly rewarding way to experience a new destination.For those seeking a true sense of luxury and indulgence, private transportation services like taxis, rideshares, or even hired drivers can elevate your sightseeing experience. While more expensive, these options offer convenience, comfort, and the ability to sit back, relax, and truly soak in the scenery without worrying about logistics.One of my most luxurious transportation experiences was hiring a private driver during a visit to Bali, Indonesia. Our knowledgeable guide not only navigated the winding roads with ease but also provided invaluable insights into the local culture, history, and hidden gems that we would have missed on our own.It was a splurge, but the personalized service and lack of stress made it well worth the investment.Of course, no discussion of transportation for sightseeing would be complete without mentioning the unique and often iconic modes specific to certain destinations. From iconic double-decker buses in London to sleek bullet trains in Japan, these unique forms of transportation can be attractions in themselves.One of my most memorable experiences was taking a traditional gondola ride through the canals of Venice. As our skilled gondolier navigated the narrow waterways, serenading us with Italian ballads, the enchanting atmosphere transported us back in time, making the journey itself a highlight of our Italian adventure.Ultimately, the mode of transportation you choose for sightseeing can significantly impact your overall experience. Whether you prefer the freedom of a rental car, the convenience of public transit, the adventure of cycling, the luxury of private services, or the unique charm of iconic local transportation, the journey itself can create lasting memories.As a student, I've learned that being open to different modes of transportation not only broadens your horizons but alsoallows you to truly immerse yourself in the local culture and embrace the spirit of adventure. So, the next time you're planning a sightseeing adventure, take a moment to consider your transportation options – it might just make all the difference in creating unforgettable experiences that will stay with you long after you've returned home.篇2What Mode of Transportation Would You Take if You Went Sightseeing?If I had the chance to go sightseeing somewhere new and exciting, the first thing I would have to figure out is how I'm going to get around. The mode of transportation you choose can really make or break a travel experience. Do you want to just kick back and relax while someone else does the driving? Or would you prefer the freedom and flexibility to go wherever you want, whenever you want? There are pros and cons to every option, but here's how I would weigh the different choices.Probably the most convenient option would be to take some kind of guided tour. That way, you've got a knowledgeable local guiding you around and making sure you don't miss any of the must-see spots. A lot of tours use coaches or small buses to getgroups from place to place. These can be a great option because you don't have to worry about driving or parking yourself. You can just sit back, relax, and take in all the sights from the window as your guide provides commentary and insights. The downsides are that you're on someone else's schedule, tours can be pretty expensive, and the buses don't exactly have the most comfortable seating if you're traveling all day.Another guided option could be to hire a private driver or even just take taxis between destinations. Having a personal driver gives you more flexibility than a group tour, but it's also pricier and you may not get as much insider info. Taxis are relatively affordable for shorter rides, but the costs can really add up, especially if there's traffic or you're crisscrossing all over. It's just not the most practical for doing a full day or more of intensive sightseeing.For seeing a city or concentrated area, one of my favorite options is definitely the hop-on hop-off bus tours. These double-decker buses have routes that stop at all the top attractions and landmarks. You can just hop off wherever you want to explore, then hop back on and continue the loop when you're ready. The buses run on a continuous cycle so you can be as spontaneous as you like. Having a live guide or at least anaudio commentary makes these really informative too. My only complaint is that the buses can get quite crowded during peak seasons.If I wanted to cover more ground and see multiple cities or regions, I would probably look into renting a car. This gives you ultimate flexibility to make your own schedule and itinerary. You're not confined to a bus route or dependent on other transportation timetables. Having your own set of wheels puts you in the driver's seat, literally! The cons are that it puts the responsibility and stress of driving on you, especially if roads are hectic or you're navigating an unfamiliar place. Plus there are the added costs of rental fees, gas, insurance, and parking to consider.Whenever possible though, my absolute favorite way to experience a new place is by foot. You just can't beat walking tours for really immersing yourself and discovering all thoseoff-the-beaten-path gems. On foot, you can wander down alleys and side streets that bus tours miss. You can pop into that intriguing cafe or market youpass by. You're not insulated behind glass, but out in the open, absorbing all the sights, sounds, and smells. The pace is low and unhurried so you appreciate every detail. The only downsides are that walking canbe tiring, especially in hot climates, and you obviously can't cover as much ground as quickly as motorized transport.For longer distances between cities or regions, I would look into taking trains. Riding the rails just has such a classic and romantic feel, doesn't it? You can stretch out, relax, and watch the scenery glide by in comfort. Trains are generally less hassle than air travel too, with more lenient security and no catching flights. The stations are usually centrally located, unlike some airports. My one gripe is that trains can be a bit slow, especially here in the States where our rail infrastructure isn't as built out as Europe's, for example. But for shorter hops, it's hard to beat the convenience and comfort of train travel.Of course, in some cases flying just makes the most sense if you need to cover vast distances quickly. I'd just try to book nonstop flights to avoid the hassles of connecting through multiple airports. Once you land, then you can look into other localized transport. The only real downsides of air travel are the extra security, the costs if you don't plan ahead, and just that general feeling of being hurried and herded around that comes with flying these days.For exploring more rural or coastal regions, I've always thought it could be awesome to go on some kind of boating orsailing tour. How cool would it be to cruise around the Greek islands on a private yacht, for instance? You could cover a lot of ground, but still get that slower, more intimate experience of arriving by sea. Ferries could be a fun and affordable option too for island hopping. I just get motion sickness pretty easily, so I'd have to plan ahead with the Dramamine!In summary, if cost was no issue and I just wanted the most seamless, effortless travel experience, I would probably go with a combination of guided tours and private transportation, whether that's buses, drivers, or even private jets for long haul flights. In reality though, I'd aim for a mix of affordable public transport, trains, and lots of good old-fashioned walking tours in order to really immerse myself in the local culture and pace. Some carefully planned self-driving could allow for additional exploring off the typical tourist trails. And maybe I'd even budget a splurge activity like a helicopter tour or boat cruise for at least one leg of the trip, just for that extra "wow" factor.No matter how you get around, I think the most important thing when traveling is to remain flexible, open to improvisation, and ready to embracing the unexpected. Some of the most memorable travel experiences often arise spontaneously when you're willing to go with the flow and take the road less traveled,whether that's literally or figuratively. The best way to experience any place is to be fully present, observant, and receptive to everything it has to offer, not just rushing through to check items off a list. So by all means, make your plans and cover all your bucket list destinations, but also leave room for serendipity. That's when the real magic happens.篇3If I Had the Chance to go SightseeingI'm just a typical student, but like most people, I dream of traveling the world and seeing everything it has to offer. There are so many incredible sights, from natural wonders to ancient ruins to modern metropolitan cities. If I could go on a fantasy sightseeing adventure, how would I choose to get around? There are a lot of factors to consider!For me, the mode of transportation is a huge part of the travel experience itself. Sure, you could just hop on a plane and get somewhere fast. But where's the fun and sense of adventure in that? I think the journey is just as important as the destination when you're exploring this amazing planet of ours.I'm an environmentally conscious person, so obviously modes of transit that are fuel-efficient and have a smaller carbonfootprint would be ideal. Taking trains, buses, bicycles, and even walking from place to place appeals to me much more than renting a gas-guzzling car or SUV. Not only are those options better for the planet, but they allow you to really immerse yourself in the local culture and sights at a slower, more intentional pace.Another factor is cost - as a student, my budget is pretty limited. I'll have to be a frugal traveler, at least until I'm done with school and earning a decent income. Many public transportation options like buses, subways, and local rail systems tend to be affordable ways to get around, especially if you buy passes instead of individual tickets. Plus, you don't have to worry about high rental fees, insurance costs, parking fees, and gas expenses that come with having your own vehicle.With those priorities in mind, let me map out my dream multi-city sightseeing adventure and how I would get around using a variety of transportation modes:The journey would have to start with a long flight from my home airport to somewhere far away and exotic - let's say Bangkok, Thailand. I'd grudgingly accept the environmental impact of the flight to get there because, from Bangkok, I could rely mainly on urban rail systems, buses, taxis, tuk-tuks, andwalking to see the beautiful temples, palaces, museums, and markets of the city.After a few days in Bangkok, I would take an overnight train through the scenic Thai countryside to the historic city of Ayutthaya. There's nothing quite like the gentle rocking of a sleeper train to lull you into a restful journey. In Ayutthaya, I'd rent a bicycle or take a tuk-tuk tour to explore the ruins of ancient temple compounds like Wat Chaiwatthanaram.The next leg would be a bus ride across the border into Cambodia, where the majestic Angkor Wat temple complex awaits outside the city of Siem Reap. I'd spend a few days hiring a tuk-tuk driver to take me around the various sites like Angkor Thom, Bayon, and Ta Prohm, the haunting jungle-enveloped ruin famous from movies like Tomb Raider.Once I'd had my fill of ancient Khmer culture, I'd continue south by bus into Vietnam. In Ho Chi Minh City, the best way to experience the frenetic energy and enterprise of the streets would be by cyclo - those iconic three-wheeled pedicabs pedaled by drivers that allow you to take in all the local sights and smells as you whiz through the city.From Ho Chi Minh City, I would board an overnight sleeper train for the long journey up the coastline to Hanoi. The historiccapital city has an amazing public transit system of buses and trains, making it easy to use as a base while taking day trips by rail out to places like Ha Long Bay and the incredible seascapes of emerald waters dotted by rocky isles.If time and budget allowed, I could then take another train into China, bound for the bustling megacity of Shanghai. The subway system there is world-class - cheap, efficient, and one of the most extensive on the planet. Between the metro andride-sharing options, Shanghai's sights like the Bund riverfront, Yu Gardens, and towering skyscrapers would be easily accessible.From Shanghai, a domestic flight could bring me to Beijing where I'd undoubtedly want to spend some time exploring the incredible historical sites like the Forbidden City, Tiananmen Square, and the Great Wall of China. Guided tours with buses and/or hiking portions would probably be the best way to fully experience those landmarks.Depending on how much longer I could extend my travels, some combination of trains, ferries, and regional flights could get me over to Japan to soak in the neon-lit modern wonders of Tokyo as well as the stunning natural beauty and old-world charm of cities like Kyoto and Nara. Between the subways,Japan's high-speed rail network, and relatively affordable domestic air travel, it's easy to get around.Of course, this is just a hastily sketched dream itinerary - realistically, a trip like that could easily take 6 months or more to do properly while still being a budget-conscious student traveler. But no matter where I ended up going, I'd want my transportation choices to reflect an adventurous, environmentally sustainable, and culturally immersive way to experience the world.Whether trains, buses, bikes, boats, tuk-tuks, or just my own two feet, getting around by multi-modal local options is half the fun of travel for me. Constantly navigating unfamiliar transit systems and routes becomes a minor adventure and learning experience itself. You have to be resourceful, flexible, and ready to get a little lost sometimes. But that's part of what makes incredible memories.You meet locals, explore hidden corners, and make unplanned discoveries that you'd never encounter just zipping from place to place by plane or private car. The journey really does become part of the overall experience when you commit to public transportation, even with the occasional hassles and inconveniences that brings.In the end, we're all just temporary visitors on this earth. If I'm fortunate enough to go sightseeing one day, I want to explore in a way that appreciates our planet,learns from other cultures, and creates a lifetime's worth of irreplaceable memories through the adventures encountered along the way. For me, multi-modal local transit will hopefully be the key to making that happen.。
