A[2020·太原市高三模拟试题] Great inventors like Thomas Edison have influenced people's lives with their inventions. While their contributions are certainly valuable, other amazing inventions were actually created by children!The trampolineTrampolines are great for both fun and exercise, but they are a fairly recent invention. In the 1930s, George Nissen was inspired to make a bouncy “net”after seeing a circus performance. He thought it more entertaining for performers to continue bouncing instead of landing in a net. So, at the age of 16, he made it by stretching thick cloth in a metal frame.The PopsicleCold weather led to the creation of a delicious invention —the Popsicle. Frank Epperson was just 11 years old when he accidentally created his first Popsicle. He was making himself a soda drink and left his glass outside overnight. When he found it in the morning, it had frozen solid with the stir (搅拌) stick still in the glass. And the first Popsicle was born.BrailleThree-year-old Louis Braille experienced a serious eye injury that blinded him in both eyes. He struggled to read by moving his fingers across raised letters, but that proved very difficult. At the age of twelve, Louis learned about a communication system where messages could be read silently with fingertips. He changed it and created Braille. It's now used around the world!BEACONWhen Hannah Herbst was just 14 years old, she was named America's Top Young Scientist for inventing a device called BEACON. After receiving a letter from her Ethiopian pen pal, Hannah was inspired to create a device that could convert the energy from ocean waves into electricity which she hopes will help people without easy access to electricity.1．Which of the inventions greatly benefits the blind?A．The trampoline. B．The Popsicle.C．Braille. D．BEACON.2．Who was awarded a national title for his/her invention?A．George Nissen. B．Frank Epperson.C．Louis Braille. D．Hannah Herbst.3．What do the child inventors have in common?A．They were all awarded for their amazing inventions.B．They all made improvements on previous inventions.C．They were all teenagers when they made their inventions.D．They all invented great things that influence people's lives.B[2020·郑州高三第一次质测]If there was a subject at school that made me anxious, it was science. Maybe that's because in my tenth grade, I couldn't understand my physics teacher's instructions, causing me to accidentally set fire to the classroom. So, when my husband and I decided to homeschool our daughters, we made a deal: he would teach science, while I would handle everything else. But that's not how things have been going these past few weeks, since my husband has been too busy to teach the girls.Recently, while out on my morning hike before starting lessons, I noticed that the sky was a beautiful blue, and the air was filled with the sweet smell of flowers. That's why I decided that the day's lessons would be taught outside, although I remembered that my daughters hadn't had any science classes from my husband for a while.I returned to the house to get the girls ready. We headed up into the forest, settling ourselves by a pond that rarely has any visitors. My daughter Saoirse started to pick up pondweed and catch frogs, while my other daughter Ula looked at me, waiting to be instructed. I handed her a drawing board and colored pencils. “We wait，” I told her, “and see if something comes along. In the meantime, just draw what's around you.”We worked for more than an hour, hardly speaking. A bird flew across the water, and then settled in front of a fallen tree. I quickly told Ula, worrying that she'd not seen the creature. But she had, and she started drawing it. An hour later, she finished her picture and I stared down at it. She drew the bird on her paper with amazing accuracy. But there was one other interesting fact about this drawing: she also drew me, sitting beside her.I realized, as I stared at this child's drawing of us watching a bird, how I'd lived for 40 years, received 10 years of higher education, and never understood the foundation of science before this moment. The foundation of science is a sense of wonder; it isn't about accurately reciting words from a textbook. It is first and foremost about stepping outside our busy lives and being amazed at the world around us.4.How did the author feel about science when in school?A．She was nervous about it.B．She was fond of it.C．She was confused about it.D．She was eager for it.5．The underlined word “it”in Paragraph 4 refers to “ ________”．A．the fallen tree B．the forestC．the bird D．the picture6．Which of the following best describes Ula?A．She's very outgoing.B．She's good at observing.C．She's very hard-working.D．She shares interests with her sister.7．What is the foundation of science in the author's opinion?A．Attention to accuracy.B．Curiosity about the outside world.C．Determination to find out the truth.D．The ability to understand teachers' instructions.C[2020·河北省高三六校联考]“The fact that the smoke reached São Paulo and blackened an afternoon proves how unusual the fires that burn in the countryside of Brazil are，” Ricardo Mello, head of the World Wide Fund for Nature's (WWF) Amazon program, said.The latest figures come at a time of international protest against the inaction of President Jair Bolsonaro's administration. In July, Brazil's National Institute for Space Research (INPE) showed data to the public, which indicated that there had been a significant rise in deforestation (毁林) rates. Particularly, the figures showed that in July 2019, deforestation had increased nearly 300 percent in comparison to the same month in 2018.Environmentalists are becoming increasingly concerned, accusing the government of encouraging deforestation and those who want to make use of the forest for commercial gain. During his time in power, Bolsonaro has moved to rob some power of government agencies that are responsible for protecting the rainforest as well as regulations covering native lands and nature reserves. Bolsonaro sees these kinds of regulations as a drag on economic growth in the Amazon region.Fire in the Amazon is used as a technique to clear land for agriculture. “Farmers clear cut land to make way for agriculture, and then wait for the dry season to set fire to clear the land so they can plant，” Mello said.“It's likely that all of these forest fires are deliberately set by humans.”Now it is the dry season in the Amazon, which means conditions in many parts of the rainforest are suitable for the fires to spread over large areas. “It is very unlikely that those fires break out naturally，” Mello said. “It is important to remember that 2019 is not a strong El Niño year. When we have strong El Niños, weather gets drier in the northern part of Brazil and this favors fires. This is not the case of 2019.”8．Why are deforestation figures of 2018 and 2019 compared?A．To share knowledge of the Amazon forest.B．To show how the Brazil president governs.C．To stress the seriousness of deforestation.D．To express the anger of environmentalists.9．What does President Bolsonaro do for deforestation?A．Weakening relevant government agencies.B．Encouraging the fight for commercial gain.C．Using techniques to clear land for agriculture.D．Defending regulations about nature reserves.10．What are the weather conditions of the Amazon when the fires break out?A．They're fit for fires to break out naturally.B．The Amazon experiences the dry season.C．They're possible for fires to spread everywhere.D．The Amazon is just in a strong El Niño year.11．What is the best title for the text?A．Jair Bolsonaro's Administration Was AccusedB．Farmers Cleared Amazon Land for AgricultureC．Unusual Rainforest Fires: Effects on Health and WeatherD．Amazon Fires: Possibly Linked to Environmental PoliciesD[2020·青岛高三练习诊断]Hybrid cars are cars that run on both petrol and electricity. They each have a small standard petrol engine and a battery and an electric motor to provide electrical power.There are some differences between different models of hybrid cars, but the general principle is that the car runs on petrol, and the electric motor kicks in when additional power is required, for example when going uphill or accelerating. In some hybrid cars the petrol engine turns itself off when not needed, for example when the car has stopped at traffic lights, keeping only the electric engine running.Conventional cars have large engines to cope with driving uphill andaccelerating. Most of the time, this high engine capacity is not needed, but the engine continues burning up fuel. Hybrid cars have much smaller petrol engines, boosted by electric motors when needed, so they use less petrol. Hybrid cars are also lighter and aerodynamically (空气动力学地) designed for greater fuel efficiency.Another way that fuel consumption is cut is by a system of “regenerative braking (刹车)”. The electric motor is used to slow down the car, rather than conventional brakes. The energy produced by the slowing car is transformed into electrical power, which is automatically stored in the battery. In effect, the battery recharges when you brake. In conventional cars the energy produced when the cars are braking is wasted.Car manufacturers and engineers have been experimenting with electric and hybrid cars since the late 19th century. In 1898 Ferdinand Porsche built an experimental hybrid car that used both an internal burning engine and electric motors. The first mass-produced hybrid car, the Toyota Prius, came out in Japan at the end of 1997. However, hybrid cars became available in the USA only in 1999, when the Honda Insight went on sale.As they use less fuel, hybrid cars are cheaper to run. There are also many initiatives in place to encourage people to buy them. In some countries, hybrid car owners pay a lower rate of tax, and don't have to pay on certain toll roads (收费公路). In some cities around the world, hybrid cars are allowed to park for free.12．What can we learn from Paragraph 2?A．Hybrid cars don't need petrol any more.B．The petrol engine and the electric motor work all the way.C．Hybrid cars mainly depend on electrical power to run.D．Some hybrid car petrol engines will quit when unnecessary.13．Which is NOT the reason why hybrid cars consume less energy?A．Smaller petrol engines. B．Scientific design.C．Conventional brakes. D．Energy storage.14．What can we infer from the last paragraph?A．Hybrid cars are cheaper to buy.B．Hybrid car owners don't have to pay tax.C．Hybrid car owners don't need to pay the parking fee.D．Hybrid cars will have a bright future.15．What's the author's purpose of writing the passage?A．To advertise hybrid cars.B．To introduce hybrid cars.C．To compare conventional cars and hybrid cars.D．To inform the development of hybrid cars.第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

本篇⽂章是为⼤家整理的⾼中英语演讲稿范⽂【5篇】，欢迎您阅读参考！【篇⼀】⾼中英语演讲稿范⽂ Ladies and Gentlemen： Today I’m glad that I’m standing here talking to you all. As the title given， I am going to talk you about a way of treating people and things in life. My speech here basically includes 2 parts， in the former of which I‘ll describe you the present occasion we teenagers are in， as well as the reason behind. Then it’s about the several opinions of mine toward the case above. Undoubtedly， every one of us has stepped into adolescence， a period of time where the most exciting and mysterious changes take place. Boys， apparently become more ambitious. Girls， in some ways， start to dream and become more sensitive about the world. All in all， as if our emotions become much stronger， somehow we’re always trapped in circles and struggling against something that can’t be changed anyway. We complain about how fragile our friendship is， how little people know about us， how unfair the life is，etc. It seems that every time we fail， we blame it to the tough conditions we’re in， while never notice a problem inside ourselves， that we’re never satisfied. Let’s just imagine that there was an old lady. What she sees was her neighbors’ being mean again while not how kind they were when they took care of her sick body. What she saw was her dog’s annoying barking while not how much loyalty it had shown.What she saw was always so depressing that it finally turned her into an unpleasant person. Think about how our life would be if we stand in her shoe. Why don’t we focus our attention on how much we’ve already got in stead？ You know it’s really simple to do as there’s a tremendous amount of examples. Like the popular Jetpack Joy Ride on your Iphone， you can enjoy it whenever you like， whereas in some poor area people don’t even know such thing as Iphone. Actually we should be thankful about the richness we’ve got， thankful that with each sunrise taking place we don’t need to starve to call it a day， thankful that the people we love are still in health， that we still got much to hold on. As a saying on website，” The world is tough， but I’m tougher.” What doesn’t kill you makes you stronger. Every day is a gift from life， all we need is to accept it， cherish the lessons life has taught us， so as to achieve our goal with high spirit. In this way， someday when we leave the world， we leave no regrets. Thank you for listening.【篇⼆】⾼中英语演讲稿范⽂ Good morning everybody， I’m very glad to stand here and give you a short speech. We all know that Bingxin has a famous saying “we always admire the beauty of flowers but its sprout was watered by tears of struggle and rained by blood of sacrifice”. So for the majority， behind their success， are filled of sweat and tears. Eagle flying in the vast firmament， must be experienced the pain of countless times fall under the cliff， then hammered out a pair of volley wings. A shinning of pearls，inevitably suffered countless body friction and numerous waves’ shock. In this view， a real successful people， and he must experienced numerous times to stand up again and agin after failed， because without sweat and tears on the life road ，no one can casually get the beautiful flowers. Alfter a heavy fall Shi Tiesheng lost his legs， it must be a heavy blow for anyone. But he didn＇t lose faith in life， but use his brain and hands to show the infinite love of life. Beethoven was blind and deaf， but he still had written the ＂Hero＂＂Destiny＂nd so on a large number of music works， in his unfortunately life， he doggedly gripped the ＂fate of the throat. They all had a fall， but they are strong enough to stand up， fight against fate and misfortune， finally they succeed. So for each of us， wrestling is not terrible，lose confidence and courage in life is the most terribe thing. In my opionion， the sweat and tears during the life’ journey are very important for us， they hone our will， and enrich our experience. As the saying goes， how can you see the rainbow without a rainy day， while you don＇t work hard and not struggle，how can you gain the successful flowers. All in all， the sweat and tears on the struggling road is inevitable， don’t look for shortcuts anymore， steadfast walk every step， we will succeed in the end. So belief yourself， nothing is impossile， just do it. Thank you for taking your time to listen to my speech， I hope in the near future we all can be successful.【篇三】⾼中英语演讲稿范⽂ Good afternoon ！ Ladies and gentlemen： I am very glad to make a speech here in this class ！ This time ， I＇d like to talk something about English .

Wow， what a dream it has been for Martin Luther King. But the changing world seems telling me that people gradually get their dreams lost somehow in the process of growing up， and sometimes I personally find myself saying goodbye unconsciously to those distant childhood dreams. However， we meed dreams. They nourish our spirit； they represent possibility even when we are dragged down by reality. They keep us going. Most successful people are dreamers as well as ordinary people who are not afraid to think bigand dare to be great. When we were little kids， we all dreamed of doing something big and splashy， something significant. Now what we need to do is to maintain them， refresh them and turn them into reality. However， the toughest part is that we often have no ideas how to translate these dreams into actions. Well， just start with concrete objectives and stick to it. Don’t let the nameless fear confuse the eye and confound our strong belief of future. Through our talents， through our wits，through our endurance and through our creativity， we will make it. Hold fast to dreams， for if dreams die， life is a broken-winged bird that cannot fly. Hold fast to dreams， for when dreams go， life is a barren field frozen with snow. So my dear friends， think of your old and maybe dead dreams. Whatever it is， pick it up and make it alive from today. Thank you！。

四年级天窗续写优秀英语作文500字左右全文共3篇示例，供读者参考篇1The Sky Window (Continued)It was a cloudy day and I was feeling bored during class. I gazed up at the sky window in the ceiling and daydreamed about adventures beyond the classroom walls. Suddenly, a glimmer of sunlight peeked through the clouds and shone down through the window onto my desk. As I stared at the bright spot, it seemed to grow larger and larger until it enveloped me in its brilliant light.The next thing I knew, I was no longer sitting at my desk but soaring high above the school! I looked down in amazement at the tiny building and grounds far below me. The sky window had transported me into the heavens. As I glided on air currents, I could see for miles in every direction. The whole town lay sprawled out like a colorful map, with streets like ribbons weaving between neighborhoods of houses, stores, and parks.Gaining altitude, I sailed up through wispy clouds that felt solid yet I could pass right through them. I wondered if this wasall a dream, but it seemed so real. Birds flew alongside me, chirping merrily. The sun was a brilliant orb giving warmth to my face. I spread my arms like wings and did loop-de-loops, laughing with exhilaration.In the distance, jagged peaks of a mountain range jutted towards the azure sky. I steered myself in that direction, eager to explore them up close. As I approached, the mountains loomed taller and taller, their snowy caps glistening. I coasted down into a valley between two towering sentinels of granite.A frozen lake reflected the rocky spires flawlessly. Overhead, a hawk circled, keeping watchful eyes out for any small creatures stirring below. I landed gently on the gleaming ice. All around was utter silence, broken only by the occasional melting drip of snowmelt. I picked up a handful of glistening powder and admired how it sparkled like diamonds.Just then, the school bell pierced the stillness. I found myself blinking in surprise, back at my desk as before. My teacher asked if I had been daydreaming again. I simply smiled and said, "Just exploring beyond the sky window." She smiled back, somehow seeming to understand. I knew my imagination could take me to wondrous places, if I just kept gazing out that magical window in the sky.篇2The Skylight Adventure (500 words)Last year, something really cool happened to me. It all started one night when I was having trouble sleeping because of a bright light shining through my bedroom skylight. I pulled the curtains shut but they got stuck halfway. That's when I noticed a glowing spaceship hovering outside my window!At first I was scared, but then a little green alien popped out and waved at me. His name was Zorg and he looked friendly enough. Zorg said his ship was having engine trouble and he needed a place to hide out for a while to make repairs. Against my better judgment, I let him come inside.Zorg was only supposed to stay for a few days, but he ended up living in my bedroom for over a month! We had to be really quiet so my parents wouldn't find out. Zorg was a ton of fun to have around. He used his anti-gravity ray to make my toys and furniture float, which was awesome. And he had a hologram projector that could turn my room into any imaginary world I wanted - a pirate ship, dinosaur planet, you name it!The only bad thing was that Zorg was a total slob. He left a mess everywhere with his weird alien food and tools. One timehe tried cooking an experimental alien meal and ended up blowing up my bedroom! That was a hard one to explain to my parents.Eventually, Zorg got his ship fixed and it was time for him to leave Earth. I was really sad to see my new alien buddy go. But before leaving, Zorg used his technology to clean every last speck of alien grime out of my room. He also shrank down his spaceship and gave it to me as a souvenir! It even still works - I can open up the hatch and tiny Zorg hologram waves hello.I'll never forget the time I had an alien roommate. It was one crazy, mess-making, out-of-this-world adventure! If Zorg ever needs a place to stay again, he's welcome back anytime. Just hopefully he doesn't bring any more of those smelly alien foods with him. My bedroom still has a funky odor I can't get rid of!篇3The Window (Continued)One day, I was staring out the window in my classroom daydreaming as usual when I noticed something strange outside. At first I thought my eyes were playing tricks on me. But as I looked closer, I could see that there was a tiny person standing on the ledge outside the window!I rubbed my eyes in disbelief. Could this be real? The little person seemed to be waving at me. I looked around the classroom but none of my classmates appeared to notice anything out of the ordinary. Maybe I really was just imagining things.But then the little person started jumping up and down, trying to get my attention. That's when I realized this was no dream - there was an actual tiny human being outside my window!Not knowing what else to do, I raised my hand. "Um, Mrs. Johnson?" I said nervously. "There's a little person outside the window trying to get my attention."Mrs. Johnson stopped writing on the chalkboard and turned around, giving me a funny look. "A little person? Outside this window?" She sounded doubtful."Yes, really! See, look!" I pointed excitedly out the window. To my relief, the little person was still there waving its arms.Some of my classmates started giggling, but Mrs. Johnson came over to the window to investigate. At first she didn't seem to see anything. But then the little person started frantically waving and jumping to get her to notice.Mrs. Johnson's eyes grew wide. "Good heavens, you're right! There is a tiny person out there!" She turned to the class in astonishment. "Children, we appear to have a visitor of the miniature variety."Immediately, every student jumped out of their seat and crowded around the window, trying to get a glimpse. The little person looked overwhelmed by all the attention and took a step back."What do you think it wants?" I wondered aloud.Mrs. Johnson tapped on the glass gently. "Hello there!" she called out in a friendly voice. "Can you understand me?"To our amazement, the little person nodded its head yes. It then pointed excitedly towards the latch on the window, motioning for us to open it."Should we let it in?" I asked Mrs. Johnson. Part of me was a little nervous about what this tiny creature might want. But I had to admit, I was awfully curious too.Mrs. Johnson considered this for a moment, then gave a decisive nod. "Well, I suppose there's no harm in that. But we must be very careful."Slowly, she undid the latch and opened the window...。

A drug is a chemical substance. It can bring about a physical, emotional, or mental change in people. Alcohol and tobacco are drugs. Caffeine, a substance found in coffee and some soft drinks is also a drug.Drug abuse is the use of a drug, legal or illegal that hurts a person or someone close to him. A drug user is the person who takes the drug. There are many kinds ofdrug users. Experimental users may try drugs one or twice. They want to see what the effects will be. Recreational users take drugs to get high. They use drugs with friends or at parties to get into the mood of things. Regular users take drugs all the time. But they are often able to keep up with the normal routine of work. Dependent users can‟t relate to anything but drugs. Their whole life centers around drugs. They feel extreme mental or physical pain without drugs.It‟s not always easy to tell if someone is using drugs. In the early stages, drug use is often hard to see.Sometimes people like drugs or need drugs so much they can‟t do without them. They can‟t do without them. They are dependent upon drugs. Only a few kinds of drugs can cause physical dependence, but almost any drug, when it‟s misused can make a person think he needs it all the time. By this time it‟s too late and the person is …hooked‟.16. What does the speaker say about drug abuse?17. What does the speaker say about recreational drug users?18. What does the speaker say about drug dependence?Passage twoAccording to Charles Harper, Chairman of Con Agra, the Healthy Choice line of frozen dinners began w ith his own heart attack. It‟s been brought on by years of eating anything he could get his hands on. As he lay in a hospital for recovering , Harper imagined the line of healthy frozen foods, the Tasty Good. The Healthy Choice product line was carefully tested with consumers before being introduced to the general public. ConAgra‟s research and development staff spent a year working under the instruction-“Whatever the cost, don‟t sacrifice taste”. The first test market results surprised even the ConAgra team: the low sodium, low fat frozen dinners sold much better than expected. According to the firms‟ vice president of marketing and sales, “We benefited from low expectations. The products were much better than people thought they would be” This finding supported ConAgra‟s decision to position a product against other high quality frozen dinners, rather than as a diet or health food. The new products brand‟s name and packaging were an important part to thedevelopment process. The name Healthy Choice was chosen for the positive implication it held for consumers. Because ConAgra felt product would be an impulse purchase, it was important to make the item stand out in a freezer case. This was accomplished through the dark green packaging that not only differed from the competitors, but also suggested freshness and richness in vitamins.19. What did Charles Harper think of while he was in hospital?20. What does the passage say about the Health Choice product line before it went to market?21. What is said to contr ibute to ConAgra‟s business success?22. What does the speaker say about the name Healthy Choice?Passage ThreeIn the United States, 36 states currently allowed capital punishment for serious crimes, such as murder Americans have always argued about the death penalty. Today, there is a serious question about this issue-Should there be a minimum age limit for executing criminals? In other words, is it right for convict murderers who kill when they are minors, that is under the age of 18, to receive the death penalty. In most other countries of the world, there is no capital punishment for minors. In the United States, though, each state makes its own decision. Of the 36 states that allowed the death penalty, 30 permit the execution of minors. In the state of South Carolina, a convicted murderer ws given the death penalty for a crime he committed while he was a minor. In 1977, when he was 17 years old, James Terry Roach and two friends cruelly murdered three people. Roach‟s lawyer fought the decision to execut e him. The young murder remained on death roll for ten years while his lawyer appealed to the governor. The lawyer argued that it‟s wrong to execute a person for a crime he committed while he was a minor. In the United States the governor of a state has the power to change a sentence from the death penalty to life in prison.

UNIT 4 单元主题训练Ⅰ.阅读理解A(2022·佛山二模)The future of space exploration may depend on an art form from the past: origami (折纸艺术), the ancient art of paper folding.Researchers from Washington State University (WSU), US, have used origami to possibly solve the problem of storing and moving fuel to rocket engines, a key challenge in space travel, according to Newswise.They've developed a foldable plastic fuel “bladder (囊状物)” resistant to super cold temperatures, which could be used to store and pump fuel in spacecrafts of the future.Their findings have recently been published in the journal Cryogenics.“Folks have been trying to make bags for rocket fuel for a long time，” said Jake Leachman, one of the lead researchers.“We currently don't do large, long-duration trips because we can't store fuel long enough in space.”Meanwhile, NASA is also looking to paper folding to help observe distant planets.The agency is currently developing Starshade, a foldable, sunflower-shaped piece of hardware that would help block starlight and enable telescopes to view distant objects more clearly in space.“A huge part of my job is looking at something on paper and asking, ‘Can we fly this？’” Manan Arya, a technologist in California, said.“Once I realized this is how you fold spacecraft structures, I became interested in origami.I realized I was good at it and enjoyed it.Now, I fold constantly.”Using origami for space purposes isn't new, however.Solar arrays (太阳能阵列), experimental wings for space shuttle programs and an inflatable (可充气的) satellite were also inspired by origami in both past and present space projects.“With most origami, the magic comes from the folding，” Robert Salazar, who helped design the Starshade and now works on the Transformers project, said in a statement.“There are so many patterns to still be explored.”语篇解读：本文是一篇说明文。

高二英语气候变迁阅读理解25题1<背景文章>Climate change is one of the most significant challenges facing our planet today. The Earth's climate has been changing for millions of years, but in recent decades, the rate of change has accelerated dramatically. Global temperatures are rising, causing a wide range of impacts. One of the most visible effects is the melting of glaciers and ice caps, which is leading to a rise in sea levels. This poses a serious threat to coastal communities and low-lying islands.The increase in temperature is also affecting weather patterns. We are seeing more extreme weather events such as hurricanes, floods, droughts, and wildfires. These events can cause significant damage to infrastructure, agriculture, and human lives.Another consequence of climate change is the disruption of ecosystems. Many species are struggling to adapt to the changing climate, and some may even face extinction. This can have a domino effect on the entire food chain.Scientists are working hard to understand the causes and consequences of climate change. They are also looking for solutions to mitigate its effects. One of the key strategies is to reduce greenhouse gasemissions. This can be achieved by increasing the use of renewable energy sources such as solar and wind power, improving energy efficiency, and reducing deforestation.In conclusion, climate change is a complex and urgent problem that requires immediate action. We all have a role to play in protecting our planet for future generations.1. What is one of the most visible effects of climate change?A. Increase in population.B. Melting of glaciers and ice caps.C. Decrease in temperature.D. Increase in deforestation.答案：B。

多孔介质内油、水介质迁移对比低温实验吴国忠;赵文浩;吕妍;齐晗兵;周英明;李栋【摘要】泄漏污染物(油水)在多孔介质内迁移特征是严寒地区输油管道泄漏检测技术发展的基础.实验模拟分析了输油管道泄漏污染物在多孔介质内迁移过程,研究了低温环境油、水在弥散型颗粒类多孔介质内的迁移规律.研究结果发现低温环境导致油水迁移发生显著变化,其迁移过程中的温度场发生明显改变,其迁移范围显著减小;相比于水相污染物,在低温环境下油相污染物迁移速度明显减缓,从而导致在泄漏处顶部发生堆积,并且最终溢出地表面.【期刊名称】《当代化工》【年(卷),期】2016(045)006【总页数】4页(P1108-1111)【关键词】多孔介质;油水;迁移;低温实验【作者】吴国忠;赵文浩;吕妍;齐晗兵;周英明;李栋【作者单位】东北石油大学,黑龙江大庆163318;东北石油大学,黑龙江大庆163318;大庆石化公司信息技术中心,黑龙江大庆163318;东北石油大学,黑龙江大庆163318;东北石油大学,黑龙江大庆163318;东北石油大学,黑龙江大庆163318【正文语种】中文【中图分类】TE832近年来我国经济和社会的进步带动了石油化工行业的高速发展。

石油作为主要的能源之一，其开采、运输和储存早已成为能源安全中的重中之重。

管道输送是石油生产过程中的重要环节，是石油工业的动脉，截止到2013年我国油气管线总长度已经从1978年的0.83万km增长到9.85万km[1]。

人为因素和自然因素会导致输油管道发生泄漏，输油管道的泄漏不仅影响了正常输送并且造成了巨大的经济损失。

输油管道泄漏检测是保障管道安全可靠运行的必要手段[2-4]，近几年来管道泄漏检测受到了广泛的研究，并取得了较好的应用效果。

国内外众多学者对多孔介质中污染物的迁移问题进行了研究。

例如，Cary等[5]通过土柱实验观察不同性质的多孔介质对水和非水相流体运动的影响。

Nam等[6]通过一维流体实验发现多级流体比单级流体更适合非饱和砂土水力特性的确定。
