The microphone is RoHS compliant – free from all substances specified in the EU directive on hazardous substances.The microphone's hypercardioid polar pattern provides a 100° angle of acceptance. Additional interchangeable elements with omnidirectional (360°), cardioid (120°) and MicroLine ® (90°) pickup patterns are available.The integral power module can be powered from any external 11V to 52V DC phantom power supply. A recessed switch in the power module permits choice of flat response or low-frequencyroll-off (via integral 80 Hz high-pass UniSteep ® filter) to help control undesired ambient noise.The microphone is enclosed in a rugged housing with a low-reflectance black finish. It features an XLRM-type connector insert at its base, allowing it to be plugged directly into an XLRF-type panel jack or microphone cable. An AT8474 low-profile isolation mount or AT8473 stand clamp is optional to permit attachment of the XLR mic base to a standard ⅝"-27 or ⅜"-16 threaded mic stand or mounting flange.The ES917aH stands 457.2 mm from the table or podium. The model output is low impedance balanced. The output connector mates with XLRF-type cable connectors. The balanced signal appears across Pins 2 and 3, while the ground (shield) connection is Pin 1. Output is phased so that positive acoustic pressure produces positive voltage at Pin 2, in accordance with industry convention.The integral 80 Hz high-pass UniSteep ® filter provides easy switching from a flat frequency response to a low-end roll-off. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, airhandling systems, etc.), room reverberation and mechanically coupled vibrations. To engage the UniSteep ® filter, use the end tip of a paperclip or other small pointed instrument to slide the switch toward the “bent” line.Avoid leaving the microphone in the open sun or in areas where temperatures exceed 43°C for extended periods. Extremely highhumidity should also be avoided.10 dB20k10k 5k 2k 1k50020010050指向特性频率特性Machida • Tokyo • Japan超心形指向性专业型双鹅颈式会议话筒ES917aH 是一枚阔频宽的电容式超心形指向性话筒，高质量的收音效能，设计于增强收音、专业录音、电视广播、会议等高要求的收音应用。

对比手法英文作文开头Title: A Comparative Approach: Exploring the Art of Contrast。
In the realm of literature and composition, employing the technique of contrast serves as a powerful tool for elucidating ideas, themes, and perspectives. Through the skillful juxtaposition of contrasting elements, writers can effectively highlight nuances, provoke thought, and engage readers on a deeper level. In this discourse, we embark on a journey to explore the intricacies of contrast in English composition, delving into its various forms, functions, and significance.At its essence, the art of contrast revolves around the comparison of distinct entities or concepts to underscore their differences or similarities. This technique not only enriches the narrative texture but also facilitates a more profound understanding of the subject matter at hand. Whether through the sharp dichotomy of opposing forces orthe subtle interplay of complementary elements, contrast infuses vitality and dynamism into literary works.One of the quintessential forms of contrast is the juxtaposition of characters within a narrative. By presenting characters with divergent traits, motivations, or worldviews, writers can effectively underscore thematic tensions and conflicts. For instance, in F. ScottFitzgerald's "The Great Gatsby," the stark contrast between the enigmatic Jay Gatsby and the pragmatic Tom Buchanan illuminates the underlying themes of illusion versusreality and the corrupting influence of wealth.Moreover, contrast can manifest through the portrayal of settings or environments within a story. The juxtaposition of disparate landscapes, such as the bustling metropolis juxtaposed with the serene countryside, can serve as a metaphorical device to underscore thematic contrasts, such as urbanization versus nature or chaos versus tranquility. Charles Dickens masterfully employsthis technique in "A Tale of Two Cities," where the stark contrast between the cities of London and Paris serves as abackdrop to explore themes of revolution, sacrifice, and redemption.In addition to its narrative functions, contrast plays a pivotal role in argumentative and expository writing. When presenting contrasting viewpoints or arguments,writers can effectively highlight the complexity of an issue and encourage critical thinking among readers. Through the artful juxtaposition of opposing perspectives, writers can construct compelling arguments that acknowledge the multiplicity of viewpoints surrounding a particular topic. This technique is particularly evident in academic discourse, where scholars engage in dialectical analysis to dissect complex issues and arrive at nuanced conclusions.Furthermore, contrast can be deployed at various levels of linguistic and stylistic composition to enhance the overall impact of a piece of writing. From the use of contrasting imagery and symbolism to the employment of antithetical sentence structures, writers employ a myriad of linguistic devices to create resonance and depth intheir works. For instance, the juxtaposition of light anddarkness in Shakespeare's "Romeo and Juliet" not only serves as a metaphor for the lovers' tumultuousrelationship but also underscores broader thematic dichotomies such as love versus hate and life versus death.In conclusion, the art of contrast represents a fundamental aspect of English composition, enrichingliterary works with depth, complexity, and resonance. Whether through the juxtaposition of characters, settings, arguments, or linguistic devices, contrast serves as a powerful tool for elucidating themes, provoking thought, and engaging readers on a profound level. As writers continue to explore the nuances of this technique, they unlock new possibilities for expression and insight, perpetuating the timeless allure of contrast in the realm of literature and composition.。
各种奇怪的声音作文英语Title: Strange Sounds: An Exploration。
Have you ever found yourself immersed in an environment where peculiar noises dance around you, teasing your senses and stirring your imagination? From the gentle rustling of leaves to the mysterious hums of the night, strange sounds surround us, sparking curiosity and wonder. In this essay, we delve into the realm of these enigmatic sounds, exploring their origins, meanings, and the profound impact they have on our lives.One of the most captivating aspects of strange soundsis their ability to evoke a myriad of emotions and thoughts within us. Consider the haunting melody of a distant train whistle in the dead of night. Its mournful tone conjures images of solitary journeys, lost loves, and untold stories shrouded in darkness. Similarly, the rhythmic tapping of rain against the windowpane can transport us to a realm of introspection and contemplation, as we listen to nature'ssymphony echoing through the night.Moreover, strange sounds often serve as harbingers of the unknown, igniting our primal instincts and heightening our senses. The sudden screech of an owl piercing the silence of the forest evokes a primal fear, reminding us of our vulnerability in the face of the wilderness. Likewise, the eerie howl of the wind on a desolate moor carries whispers of ancient mysteries and forgotten tales, stirring the imagination with visions of spectral apparitions and otherworldly encounters.But not all strange sounds inspire fear or melancholy; some hold the promise of joy, excitement, and adventure. The infectious laughter of children at play resonates with the pure, unbridled joy of youth, infusing the air with a sense of warmth and innocence. Similarly, the jubilant chirping of birds heralds the arrival of spring, awakening dormant spirits and filling the world with renewed vitality and hope.Intriguingly, the meaning and significance of strangesounds vary greatly depending on cultural context and personal experience. What may be perceived as ominous in one culture could be regarded as auspicious in another. For instance, the low rumble of thunder may be interpreted as a sign of impending doom in some societies, while in others, it is seen as a cleansing force, purifying the earth and bringing forth new life.Furthermore, advancements in technology have introduced a plethora of new and unfamiliar sounds into our lives, further enriching our auditory landscape. The hum of machinery, the beep of electronic devices, and the whirring of engines have become ubiquitous in modern society, shaping our perceptions and interactions with the world around us. Yet, amidst the cacophony of urban life, the allure of nature's symphony still beckons, reminding us of the inherent beauty and complexity of the natural world.In conclusion, strange sounds are a fascinating aspect of the human experience, capable of evoking a wide range of emotions, thoughts, and sensations. Whether haunting or harmonious, they serve as reminders of theinterconnectedness of all things and the inexhaustible wonders of the world we inhabit. So, the next time you find yourself captivated by an unfamiliar sound, take a moment to listen, for within its mysterious melody lies a world of untold stories waiting to be discovered.。
两首诗的对比英语作文In the realm of literature, poetry stands as a testament tothe human condition, often encapsulating profound emotionsand thoughts within a structured form. This essay aims to compare two distinct poems, each with its unique style, theme, and emotional resonance, to explore the diverse ways poets express their visions.The first poem under consideration is "Do Not Go Gentle into That Good Night" by Dylan Thomas. This villanelle is afervent plea from a son to his father, urging him to fight against the dying of the light, which is a metaphor for death. Thomas employs a powerful refrain, "Do not go gentle intothat good night," which recurs throughout the poem, creatinga sense of urgency and defiance against the inevitable. The poem's structure, with its strict pattern of rhyme and repetition, mirrors the intensity of the message it conveys. The use of imagery, such as "rave about," "blaze," and "snuff," evokes a passionate struggle against the end of life.In contrast, the second poem, "The Road Not Taken" by Robert Frost, presents a contemplative moment where the speaker stands at a fork in the road, musing over the choices madeand the ones not taken. Frost's poem is characterized by its narrative style and the exploration of the concept of free will. The poem is structured in four quatrains with an ABAAB rhyme scheme, which lends a rhythmic quality to thereflective tone. The central metaphor of the two divergingroads in a yellow wood encapsulates the human experience of decision-making and the consequences of those decisions. Frost's language is more subdued, using nature as a backdrop to the speaker's internal dialogue, with phrases like "two roads diverged in a wood" and "I took the one less traveled by" to illustrate the moment of choice.Comparing these two poems reveals the poets' different approaches to profound life themes. Thomas's work is a passionate outcry against the acceptance of death, while Frost's is a quiet reflection on the paths we choose in life. "Do Not Go Gentle into That Good Night" is a call to arms, urging the reader to resist passively succumbing to fate. In contrast, "The Road Not Taken" invites the reader to ponder the significance of the decisions we make and the roads we do not walk down.In terms of emotional impact, Thomas's poem is more immediate and visceral, with its urgent refrain and vivid imagery. Frost's poem, however, offers a more subtle and lasting impression, encouraging the reader to engage in introspection and consider the impact of life's choices. Both poems are powerful in their own right, but they achieve their effects through different means: one through the force of its plea and the other through the gentle nudge of its narrative.In conclusion, the comparison of "Do Not Go Gentle into That Good Night" and "The Road Not Taken" showcases the breadth of human emotion and the diversity of poetic expression. While Thomas's poem is a vibrant and forceful declaration against the end of life, Frost's poem is a thoughtful meditation onthe choices that define our existence. Both poems are enduring examples of the poetic craft, each offering a unique perspective on the human condition and inviting readers to reflect on their own experiences and the paths they have chosen to follow.。
对比手法写景色的作文英文回答：When it comes to describing scenery, the use of comparison is a powerful technique that can help paint a vivid picture in the reader's mind. Comparing different elements of nature or landscapes can bring out the beauty and uniqueness of each scene.For example, when I think of a serene lake at sunset, I can't help but compare it to a giant mirror reflecting the colors of the sky. The calm water acts as a perfect canvas for the vibrant hues of the setting sun, creating a breathtaking sight that is both peaceful and mesmerizing.On the other hand, if I were to describe a dense forest in the early morning, I might compare it to a mysterious labyrinth filled with secrets waiting to be discovered. The towering trees and thick undergrowth create a sense of mystery and adventure, making it feel like a world of itsown.By using comparisons like these, I can convey the beauty and atmosphere of different landscapes in a way that is engaging and evocative. It allows the reader tovisualize the scene in their mind and feel a deeper connection to the natural world.中文回答：当谈到描述景色时，对比手法是一种强大的技巧，可以帮助读者在脑海中描绘出生动的画面。
骑自行车尴尬的事初中英语作文全文共3篇示例，供读者参考篇1An Embarrassing Bicycle IncidentIt was a sunny spring day, and I was feeling excited to ride my bike to school. I had just gotten a cool new mountain bike for my birthday, and I couldn't wait to show it off to my friends. Little did I know, that day would become one of the most embarrassing of my entire middle school career.I hopped on my bike and started pedaling down the street, the fresh morning breeze whipping through my hair. I loved the feeling of freedom that riding a bike gave me. As I approached the intersection near the school, I noticed the crossing guard wavingChildren to cross the street. Rather than dismounting my bike like I probably should have, I decided to show off a bit.I picked up speed and bunny-hopped the curb, sailing across the crosswalk with my wheels barely touching the ground. As I landed, I heard a loud popping sound and felt my seat start to shift beneath me. The seat post had snapped in half, likely from too much air-time during my attempted stunt.Suddenly, I found myself seated directly on the bike's metal frame, pedaling furiously with my tailbone taking the full brunt of each bump in the road. The pain was intense and caught me completely off-guard. I must have looked absolutely ridiculous - a kid manically pedaling along with their rear end just inches off the pavement.As if that weren't bad enough, when I finally made it to the school's bike racks, I realized I had another problem. With no seat on my bike, I couldn't lock it up properly. The U-lock wouldn't reach around the frame without the seat there to give it height.I briefly considered just leaving my bike unlocked and hoping for the best. But after purchasing it with my hard-earned birthday money, I knew I couldn't risk it getting stolen. So I did the only thing I could think of - I carried the stupid bike, all 30 pounds of it, into school with me.You can imagine the looks and comments I got from other students as I hauled my broken bike down the hallway toward my locker. "Nice bike, loser!" and "Why'd you bring your bike inside?" were a few of the kinder remarks. My face burned with embarrassment as I tried my best to ignore the jeers and laughter.When I finally made it to class, I had to explain the whole ridiculous situation to my teacher, who looked bemused but surprisingly understanding. She allowed me to store the bike in the back corner of the room for the rest of the day. So there sat my once-prized possession, a sad reminder of my failure looming over my shoulder for every lecture and test.The final insult came at the very end of the school day. When the dismissal bell rang, I hefted my bike back over my shoulder and began the long march home. About halfway there, the bike's metal frame dug into my shoulder blade just right, causing me to completely lose my grip. The bike went clattering to the pavement in a far-too-public location.A group of girls from my class just happened to be walking by at that moment. They saw the whole mortifying scene unfold and broke into hysterical laughter, doubling over and howling as tears streamed down their faces. Their unrestrained cackles echoed in my brain, making the embarrassment cut even deeper. I'm quite sure my face must have been roughly the shade of a ripe tomato as I quickly re-shouldered the bike and beat a hasty retreat.When I finally made it home, sweaty and exhausted from hauling around the busted bike all day, the first thing I did wascall the shop and order a new seat post. While waiting for it to arrive, I kept my bike locked up at home, refusing to subject myself to any further ridicule.To this day, more than a decade later, I still cringe at the memory of that day. Anytime I see a kid popping a bunny-hop or grinding a curb on their bike, I think back to my own stunt gone terribly wrong and feel a phantom pain in my tailbone. It was an embarrassment I wouldn't wish on any middle schooler.Looking back now, I can certainly laugh at the absurdity of the whole situation. But in that moment, as a self-conscious teenager just trying to look cool in front of his peers, the embarrassment was absolutely mortifying. I learned a valuable lesson about overconfidence that day, and made sure to take it a bit easier on the stunts after that. Sometimes it's better to just keep your wheels on the ground.篇2An Embarrassing Bike RideIt was a sunny spring day, and I was feeling great as I hopped on my bicycle to ride to school. The weather was perfect – not too hot and not too cold. I loved riding my bike on nice days like this. It was such a refreshing way to start the morning comparedto being crammed into a car or bus. As I pedaled along thetree-lined streets, I could smell the blossoms and fresh cut grass.I practiced popping little wheelies, feeling like a kid again instead of an awkward middle school student.I was about halfway to school when I saw her up ahead –Brittany Harrison, one of the prettiest and most popular girls in my grade. My heart started racing just looking at her long blonde hair blowing in the breeze as she stood on the sidewalk talking to a couple of her friends. They all looked so cool and confident in their stylish outfits. I immediately becameself-conscious of my disheveled appearance in my worn-outt-shirt, gym shorts, and beat-up sneakers.I thought about taking a different route to avoid them, but it was too late – Brittany had already spotted me. I couldn't turn around now without looking like a total loser. I tried to play it cool, giving them a friendly head nod as I approached. But then disaster struck.As I tried to do a little bunny hop over a crack in the sidewalk, I hit it at just the wrong angle. The next thing I knew, I was flying over the handlebars, my bike clattering to the ground with me landing hard right at Brittany's feet! In a panic, I must haveinadvertently clipped her leg with my foot because she went tumbling down too, dropping her books and bags everywhere."Oh my god, are you okay?" I asked, feeling mortified as I scrambled to my feet, my face blushing furiously."You idiot! Look what you did!" she screamed, gesturing to the grass stains on her cute sundress.Her friends started cracking up laughing at the ridiculous scene. I desperately wanted to melt into the concrete, wishing I could just disappear. Why do these humiliating things always happen to me in front of people I'm trying to impress?"I'm so sorry, it was just an accident," I mumbled, quickly grabbing my bike and trying to beat a hasty retreat. But the bike chain had come loose, and as I bent down to fix it, I realized my shoelaces were untied. In my flustered state, I tripped over the laces, landing flat on my face in the street!The hysterical laughter from Brittany and her friends was almost too much to bear. Tears started welling up in my eyes from humiliation as I finally gathered up my bike and stormed off down the street, trying my best to maintain at least a shred of dignity. Fat chance of that after sprawling out at Brittany's feet not once, but twice!When I finally made it to school, I could barely concentrate in class. I kept replaying the mortifying scene over and over again in my mind, cringing each time. I'm sure videos of my wipeout were already spreading like wildfire all over social media. By lunchtime, everyone would know what a total klutz I am. I dreaded facing Brittany again after almost taking her out on my bike. She must think I'm the biggest loser on the planet.As I slumped down at a vacant lunch table, bag over my face, I overheard a couple girls giggling and whispering, "Did you see that video of Ben wiping out in front of Brittany this morning?"Here we go, I thought, preparing for total and complete mockery. To my surprise though, one of the girls said, "That was actually pretty impressive how he ate it not once, but twice like that! He's got some serious guts to keep on riding after embarrassing himself like that in front of Brittany and her crew. I don't know if I could have handled that.""Yeah, you gotta admire his resilience," her friend replied. "Not many guys would have the confidence to just get up and keep going like that after faceplanting in front of their crush. Ben's pretty badass!"I couldn't believe what I was hearing. All this time, I had assumed being the subject of a viral embarrassing video was theworst thing that could happen to a middle schooler. But from their perspective, it actually made me look...cool? Suddenly, I didn't feel like quite as much of a loser.I learned an important lesson that day – true confidence isn't about never making mistakes or embarrassing yourself. It's about how you handle it and keep on going, even in the most cringeworthy situations. Yeah, my bike wipeout was absolutely mortifying in the moment. But by getting back up, dusting myself off, and continuing on my way, it took a lot moreself-assurance than just giving up or trying to hide from the embarrassment.From that point on, I stopped worrying so much about what other people think or trying so hard to look cool all the time. I just focused on being more confident in myself and not getting bent out of shape over little setbacks or embarrassments. Because you know what? We all have those awkward, humiliating moments – every single one of us. It's not about avoiding them, but embracing them with humor and grace. That's true confidence.篇3An Embarrassing Bike RideI'll never forget the day I experienced one of the most embarrassing moments of my young life. It was a sunny spring afternoon, and I had just finished classes at Smith Middle School. My best friend Jake and I decided we wanted to go downtown to grab some food and hang out like we did most days after school.The only problem was that my mom was working late, so I didn't have a ride. Jake said it was no big deal though, and that we could just ride our bikes downtown. It was only about a15-minute bike ride from the suburbs where we lived. I hadn't ridden my bike much lately, but I agreed since it was such a nice day.I got my old blue Huffy out of the garage and did my best to pump up the tires, which were looking a little flat. Once I got them filled up, I was ready to go. Jake and I headed out, riding side-by-side down the neighborhood streets.At first, everything was totally fine. We were cruising along at a good pace, and I was feeling pretty confident on my bike. Maybe a little too confident... That's when things started to go wrong.We came up to a pretty steep downhill stretch, and Jake took off ahead of me. Not wanting to be shown up, my competitiveinstincts kicked in. I leaned forward, pedaling hard to pick up speed and try to catch him.That's when I heard a bizarre "pop-flap-flap-flap" kind of sound coming from my bike. I looked down to see that my chain had come loose and was bouncing all over the place! I tried pulling the brakes, but it was too late - the chain had totally jammed up my back wheel.Before I knew what was happening, my bike went into a violent shaking motion, almost vibrating with how stuck the chain was. I couldn't control it at all, and the next thing I knew, I had been thrown clear off the bike!I went flying off to the side, hitting the grass pretty hard and getting the wind knocked out of me. My bike kept going for a few more feet before clattering to the ground in a heap of bent metal and rubber.I must have made quite a spectacular crash, because I looked up to see Jake doubled over laughing so hard he could barely breathe. A couple of cars had even stopped, with the drivers looking over in concern to see if I was okay.As I tried to catch my breath and pull myself up off the grass, incredibly embarrassed, I saw that the entire chain had comeloose and was now twisted around the rear wheel. The back tire was bent at an awkward angle, and I could see that the frame had been bent too from the force of the impact."Dude, are you alright?" Jake managed to get out between gasping laughs. I just shook my head, my face blushing redder than a tomato. Not only had I just taken an incredibly graceless spill right in front of my best friend, but my bike was now completely totaled too.The drivers who had stopped got out and came over to check on me, thankfully seeing that I was just shaken up with a few cuts and bruises. One guy commented, "I haven't seen a wipeout like that since my kid tried to jump his bike off the stairs!"As people started to gather around the scene of the accident, I felt like I wanted to just disappear into the ground from embarrassment. Here I was, now the focus of tons of strangers' attention after making a total fool of myself in epic fashion.Jake was finally able to compose himself enough to come help me pick up what was left of my mangled bike. "I can't believe you just ate it like that dude! That was insane!" he kept saying over and over.We got my poor Huffy lifted up, the crumpled chain hanging off it limply. I gave Jake an annoyed look. "Yeah, thanks for stating the obvious," I grumbled. "Now how am I gonna get this piece of junk home?"That's when one of the stopped drivers, a nice middle-aged man, spoke up. "Tell you what, I've got a pickup truck right here. Why don't you toss that bike in the back, and I can give you boys a ride wherever you need to go?"Enormously grateful for the saving grace, I gratefully accepted. As Jake and I heaved the twisted remains of my bicycle into the man's truck bed, he leaned over with a friendly smile."Don't feel too bad, kid. Everybody eats pavement with their bike sometimes when they're learning. At least you provided some entertainment for all of us passersby today!" He let out a hearty chuckle.Jake and I climbed into the truck cab, and I gave the man my address. As he drove us home, I sat in awkward silence, replaying the catastrophic bike crash over and over in my head. So much for my plans of cruising into town looking cool.When we pulled up to my house, I thanked the man profusely for his help. He just smiled and waved it off. "No problem at all! Just try to keep the rubber side down next time!"As Jake and I unloaded my demolished bike from the truck, I shot him a look. "Not a word about this to anyone, got it?" He put his hands up defensively but couldn't stop a grin from spreading across his face."Whatever you say, Mr. Stoker Stuntman!"I groaned, pretty sure this embarrassing incident would give Jake teasing material for ages. I wheeled the bent and twisted metal of what had previously been my trusty bicycle into the garage, wondering how I'd be able to face showing my face at school on Monday.At least I had learned an important lesson that day - that bike maintenance is important, and that you should never let overconfidence make you do something reckless. But most importantly, I learned that the only thing worse than a painful bike crash is having it happen in such a public, embarrassing way!。
对比模仿英语作文Lost in the maze of my thoughts, wandering aimlessly through the corridors of uncertainty. The echoes of doubts reverberate in the hollow chambers of my mind, drowning out the whispers of reason.A burst of laughter, genuine and infectious, echoing through the crowded room. It's like a melody, weaving its way through the cacophony of voices, leaving behind a trail of smiles in its wake.Raindrops cascade down the windowpane, tracingintricate patterns against the glass. Each drop a tiny universe, reflecting the world outside in its shimmering surface.The taste of nostalgia lingers on my tongue,bittersweet and comforting. Memories swirl like wisps of smoke, dancing in the dim light of recollection.The city streets pulse with life, a symphony of honking horns and bustling footsteps. Each passerby a protagonistin their own story, weaving in and out of the narrative of urban existence.In the quiet embrace of solitude, I find solace. The world fades away, leaving behind only the gentle rhythm of my own heartbeat.The pages of my notebook are a canvas, waiting to be filled with the colors of my imagination. Each word a brushstroke, painting a portrait of emotions too complex to express.The first light of dawn breaks through the darkness, illuminating the world with a golden hue. It's a reminder that even in the darkest of times, there is always a glimmer of hope on the horizon.。
