高中英语选择性必修三第四单元作文全文共6篇示例，供读者参考篇1Here's an essay on the theme of Unit 4 of the Senior High School English Elective Course 3, written in a style suitable for elementary school students, with a length of around 2,000 words:Once upon a time, there was a little girl named Emily who loved to explore the world. One sunny day, she went on a big adventure to a faraway land called Explorationville.When Emily arrived in Explorationville, she was amazed by all the sights and sounds. Tall buildings touched the sky, and people from all over the world walked the busy streets. "Wow!" exclaimed Emily. "This place is so different from my little town!"As Emily wandered through the city, she noticed that everyone spoke different languages. "Excuse me," she said to a friendly-looking woman, "could you please tell me what language you're speaking?"The woman smiled and replied, "Certainly! I'm speaking Spanish. It's the language of my home country."Emily's eyes grew wide with curiosity. "Spanish? I've never heard of that before! Could you teach me some words?"The kind woman nodded and taught Emily how to say "hello" and "thank you" in Spanish. Emily repeated the words, her tongue stumbling over the unfamiliar sounds.As she continued exploring, Emily met people speaking French, Mandarin, Arabic, and many other languages she had never heard before. With each new language, she learned a few simple phrases and stored them in her memory like precious treasures.One day, Emily came across a group of children playing a game in the park. "Can I join you?" she asked shyly.The children looked at her curiously, then one of them said, "Sure, but you'll have to learn our language first."Emily's face fell. "But there are so many languages in this city! How can I possibly learn them all?"Another child spoke up, "Don't worry, we'll teach you. That's the best way to make new friends in Explorationville!"Over the next few days, the children patiently taught Emily their language, bit by bit. They played games, sang songs, and told stories, and with each interaction, Emily's understanding grew.Finally, the day came when Emily could speak the language fluently. She joined the children's game, laughing and chatting with her new friends as if she had known them her whole life.From that day on, Emily made it her mission to learn as many languages as she could. She discovered that each language unlocked a new world of stories, traditions, and perspectives. By speaking the languages of her friends, she could connect with them on a deeper level and appreciate the richness of their cultures.Emily's adventures in Explorationville taught her that language is the key to understanding and friendship. No matter where she went or who she met, she could always find a way to communicate and learn from others.And so, Emily continued exploring the world, one language at a time, with an open heart and a curious mind, making friends wherever she went.The end.篇2Unit Four Super Cool Times!Hey guys! I'm gonna tell you all about the awesome Unit Four we learned in my big sister's English class. It was sooooo interesting!First up, they learned about different cultures and countries around the world. My sister said they read stories from peeps in Egypt, China, India and more. She showed me pictures of ancient buildings and temples that looked crazy cool! Like these huge stone pyramids from Egypt - I wanna climb to the top of one of those. And there were beauuuutiful palaces in India with colorful paintings on the walls. So pretty!Then they studied about different foods from various places. My sis brought home this reallllly spicy curry from an Indian recipe. I only had a tiny bite but my mouth was on fire! She also made some yummy dumplings from China. Those were delicious, especially dipped in that soy sauce stuff. I wanna travel around and try out all the yummy foreign foods when I'm older.But listening to my sis talk about those other countries made me a little sad too. She said lots of people there are very poor and don't have enough food or clean water or nice homes to livein. That's just not fair! Why should some people struggle so much while others have everything they need? My sis's English teacher talked about ways we can help, like donating money to charities that build wells for fresh drinking water. I'm gonna start saving my allowance to give some cash for a good cause.Another highlight was learning about different holidays and festivals in various cultures. They watched videos of these amazing celebration parades in places like Brazil and Spain. The music, dancing, bright costumes - it all looked like one big party! My parents never let me stay up late but I wish I could go dance in the streets till midnight like they do during those festivals. Maybe when I'm a grown-up.One thing that really stuck with me was when my sister's class read first-hand accounts from kids in developing countries. Get this - some kids can't go to school at all because they have to work long hours to help support their family! That made me realize how lucky I am to be able to spend my days just playing and learning. From now on, I'll defo stop whining about having to do my homework.At the end of the unit, the students had to write a paper about an issue facing the global community. My sis pick lack of education opportunities as her topic. She put together a realgood argument about how every child deserves a quality education no matter where they're born or how rich/poor their family is. I helped her do research online and make her powerpoint slides. It was fun getting to be her assistant on such an important project!Yeah, so that's the scoop on Unit Four - cultures, foods, celebrations, global issues and more. Pretty heavy stuff for a high school class if you ask me! But I guess learning about how other people live is the first step to becoming a citizen of the whole world. My sis said this unit really opened her eyes and made her want to travel more to experience different cultures firsthand. I can't wait until I'm old enough to start exploring this great big world of ours!篇3High School English Selective Unit 4 EssayHello friends! Today I want to tell you all about what we learned in my big brother's high school English class. He is taking this really cool selective unit called Unit 4. It's all about different cultures and how people live in other parts of the world. I think it's super interesting!The first part was about food from different countries. Did you know that in Italy, they eat these long noodle things called pasta? And they put red sauce made from tomatoes on top. It looks kind of weird to me, but my brother says it's really yummy. In China, they use these stick things called chopsticks to eat their food instead of forks. That seems really hard! I tried using chopsticks once and everything fell all over the place. I'll stick to forks, thanks!Then they learned about holidays in different cultures. The teacher talked about this holiday called Diwali that they celebrate in India. People light up their houses with tons of little lamps and set off fireworks. It sounds so pretty! For Chinese New Year, families get together and have huge feasts with special dishes like dumplings. The kids get money in little red envelopes too - how cool is that? I want to celebrate Chinese New Year now.My favorite part was when they studied traditional clothes from around the world. In Scotland, there are these skirts called kilts that the men wear. They're kind of like skirts but they're for boys and men, isn't that funny? In Mexico, they have these bright, colorful dresses called huipiles that women wear. They'reembroidered with beautiful designs and flowers. If I could have any traditional clothes, I'd want one of those for sure!The class also talked about music and dancing in other cultures. My brother showed me videos of these amazing Aboriginal dances from Australia. The dancers had cool body paint designs and they stomped their feet and made rhythms with sticks. We learned that in Bali, they have these gamelan orchestras that play on metallophones and gongs and drums. The music sounds so mystical and magical. I want to see a real gamelan performance someday!For celebrations, we read about this festival in Spain called La Tomatina where people legit THROW TOMATOES at each other! Can you imagine? It's supposed to be fun but I think I'd get scared if a tomato came flying at my face. We also learned about Día de los Muertos or Day of the Dead in Mexico. This is when people build altars with flowers, food, and pictures to honor their relatives who have passed away. It's a happy celebration of their lives instead of being sad. I think that's such a nice idea.Ooh, and they studied about folk tales too! Like the story of Mufaro's Beautiful Daughters from Zimbabwe. It's about these two sisters who go to visit a king, but one sister is kind while theother is selfish. Guess which one the king likes better? We also read about Anansi the Spider, who's a trickster character from West African folklore. He's always getting himself into funny messes because he tries to trick others and gets tricked himself. Haha, Anansi stories are hilarious!At the end, the class had a big project where they had to pick a country and make a presentation about its culture. My brother chose Japan and made this awesome poster all about anime, sushi, samurai warriors, cherry blossoms, and more. Some kids did dances or cooked traditional foods from their chosen countries. It looked like such an amazing project, I want to do something like that when I'm older!Well, that's everything I can remember about Unit 4 from my brother's English class. Wasn't that unit just totally fascinating? Learning about all the incredible cultures around the world makes me want to be an explorer when I grow up so I can see them for myself. A world traveler - yeah, that's what I'll be! I'll go everywhere and try all the yummy foods and see the traditional dances and wear colorful clothes from every single country. Experiencing different cultures has to be the most fun thing ever. I'll make sure to tell you guys all about my adventures when I'm aworld traveler, okay? But for now, I'm off to beg my parents for some chopsticks to practice with. Thanks for listening, friends!篇4High School English is Super Hard!Hi there! My name is Timmy and I'm in 5th grade. My big brother Jimmy is a junior in high school and he's taking this really hard English class. It's called "Optional Course 3, Unit 4" or something like that. Anyway, he's been stressing out about it a lot lately so I wanted to write about what it's like from my point of view as his little bro.First of all, the textbooks for that class are huuuuuge! I'm talking like 500 pages at least. And they're filled with all these big words and long reading passages that look crazy boring to me. Just flipping through them makes my head spin. How does Jimmy even stay awake reading all that stuff? He must be part robot or something.Then there are all the essays and writing assignments he has to do. Like, every week it seems like he's slaving over his computer, typing away furiously. His typing is so fast it's just a blur on the screen. I don't know how he doesn't get his letters all jumbled up and misspell everything. Mrs. Baker, my Englishteacher, would have a fit if I turned in papers with that many mistakes.But you know what might be the worst part? The literature analysis! Oh man, Jimmy complains about that constantly. He'll read one of those super old books or plays like Shakespeare stuff, and then he has to write these in-depth essays analyzing all the deeper meanings and symbolism and whatever. It sounds like torture if you ask me. Why can't they just read fun, easy books for kids like Captain Underpants?Despite all the hard work though, I don't think Jimmy totally hates Optional Course 3 Unit 4. He definitely complains a lot, but I can tell he's kind of into it too. Like when he's working on his essays late at night, he gets this really focused look on his face. And sometimes I'll catch him reading those dusty old books for fun when he doesn't have an assignment due. He must be a super genius or something to actually enjoy all thatbrain-melting stuff.Anyway, that's my take on what Jimmy's crazy hard English class is like. I'm just a kid so I might be totally off base, but it seems incredibly difficult to me. I don't know how high schoolers like my bro do it! I guess they must drink a lot of energy drinks or something to stay awake. Maybe I'll understand it better whenI'm older and my brain is fully developed. But for now, I'm perfectly happy sticking to fun stuff like math games and recess. Let me know when they make an English class just about bodily function jokes and I'll be all over it! Catch you later!篇5High School English is Super Fun!Hi everyone! My name is Li Lei and I'm 9 years old. I'm in 4th grade at Sunshine Elementary School. I love learning English and can't wait until I get to high school to take even more English classes!My teacher Miss Zhang says that when I get to high school, I'll get to take this really cool class called "Selective Required English Course 3". Isn't that the greatest name ever? It sounds so mysterious and exciting! I asked Miss Zhang what that class is all about and she told me something really amazing.In Unit 4 of that class, you get to learn all about different cultures from around the world! How awesome is that? Imagine getting to travel the globe and experience all kinds of new traditions and customs, all without even leaving your classroom. I can't wait!Miss Zhang says in that unit, you read stories and watch videos about different countries and communities. You learn how people live, what kinds of food they eat, what holidays they celebrate, and so much more. It's like taking a trip to every corner of the planet!One of the cultures I'm most excited to learn about is Native American culture. I saw a movie once with indigenous people living in tents made of animal skins and hunting buffalo. They had these incredible feathered headdresses and did dances around a big fire. Their lives looked so cool and different from mine. I really want to understand more about their beliefs and traditions.Another culture that sounds fascinating is life in rural villages in developing countries. Miss Zhang told me how in some places, kids my age have to walk for miles just to get water from a well or stream. They live in little huts made of mud and grass. No PlayStations or iPads, just playing outside and helping their families farm and raise animals. It's hard for me to even imagine!Then there are island cultures in the tropics where people live right on the beach and get their food from fishing in the ocean. They make grass skirts and do special dances to celebratethe full moon. How beautiful and peaceful that must be, living so simply and connected to nature.Of course, we'll also learn about cultures that are probably more familiar to me, like those in big cities across Europe, North America, and East Asia. But I bet even those will have tons of fascinating traditions and customs that are new to me. Like different holidays, foods, styles of clothing, and more. I can't wait to compare the similarities and differences between all these diverse ways of life.More than just learning about the cultures though, Miss Zhang said we'll discuss major issues impacting cultural communities around the globe. Things like preserving endangered languages, protecting indigenous lands from development and environmental damage, and helping cultural minorities maintain their unique identities and heritage. Those are such important topics that I don't really understand now, but I'm eager to learn more about how different cultures face challenges in today's changing world.I'm especially excited because Miss Zhang says in that unit, we'll get to do lots of cool projects and activities too! We might try our hand at crafts and arts from other cultures like weaving baskets, making tribal masks, or practicing traditional dances.We could cook up exotic dishes from distant lands or maybe even put on a cultural festivalwith food, music, and performances from around the world. How fun would that be?The absolute best part though, is that for our final assignment, Miss Zhang said we might get to actually meet people from some of the cultures we study! Can you imagine having visitors come into our classroom from completely different backgrounds and ways of life? We could ask them questions, hear their stories firsthand, and really get a genuine understanding of their rich traditions and heritage. I'll never forget an experience like that!Overall, I'm just so psyched to take the Selective Required English Course 3 when I'm in high school, especially Unit 4 on cultural diversity. Exploring vibrant cultures from every continent and corner of the globe just sounds like a total blast. I know it will help me appreciate the amazing diversity of people in our world. And who knows, maybe I'll even discover some cultures that I fall in love with and want to explore even more one day through traveling or cultural exchanges!Well, that's all for now. Thanks for reading my essay! I need to go practice some English word games that Miss Zhang assigned to get me ready for high school. But I'll be countingdown the days until I'm finally old enough for that Selective Required English 3 class. Classes don't get much cooler than learning about cultures from around the world!篇6High School Life is Super Cool!Hey there! I'm going to tell you all about high school and why it's just the best ever. Get ready, because this is gonna be awesome!So first up, the subjects we learn are really interesting. In middle school, it felt like we were still treated like little kids, but in high school, the teachers respect us way more as young adults. The classes cover such a wide range of topics that there's something for everyone to enjoy.My favorite is definitely biology. We get to do all these crazy experiments like dissecting frogs and growing bacteria cultures. It's so hands-on and fun! Not to mention, the teacher Mr. Paulson has the most amazing stories about his college。
必修三Unit 4 Astronomy: the science of the stars三. 阅读理解AEnglish is fast becoming the language of science around the world, but what is its future among everyday speakers? One expert points out that the percentage(比率) of native English speakers is declining(降低) globally while the languages of other rapidly growing regions are being spoken by increasing numbers of people. But English will continue to remain widespread and important.However, British language scholar David Graddol says English will probably drop in dominance(主导) by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. “The number of people speaking English as a first language c ontinues to rise, but it isn’t rising nearly as fast as the numbers of many other languages around the world, simply because the main population group has been largely in the less developed countries where languages other than English have been spoken,” he says.In a recent article in the journal Science, Mr. Graddol noted that three languages that are not near the top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil, and Malay, spoken in south and Southeast Asia.David Crystal, the author of the Cambridge Encyclopedia of the English Language, says about 1.5 billion of the world’s six billion people speak it as a second tongue compared to the 400 million native speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the future of its dominance. “Nobody quite knows what’s going to happen because no language has been in this position before. But all the evidence (证据) suggests that the English language snowball is rolling down a hill and is getting faster,” he said.36. In David Graddol’s opinion, English will _______.A. remain widespread and importantB. be more important than any other languageC. lose its dominant positionD. die away in the near future37. The underlined sentence in the last paragraph implies that ______.A. snowballs will roll down faster than language ballsB. the English language snowball is rolling down faster than any time in the pastC. English language will soon drop in dominanceD. more and more language users will choose English38. How many experts does the passage mention who express their ideas about the future of English?A. 2.B. 3.C. 4.D. 5.39. According to David Graddol, which of the following will possibly be one of the languages that will be most widely spoken?A. Malay.B. Arabic.C. Urdu.D. German.40. What should be the best title for the passage?A. English Remaining the Dominant PositionB. The Future of English? Who Knows?C. Opinions from Different ExpertsD. The English Language Snowball Rolling DownBLanguage learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises.Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can har dly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation（模仿）leads on to deliberate（有意的）imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.41. Before children start speaking________.A. they need equal amount of listeningB. they need different amounts of listeningC. they are all eager to cooperate with the adults by obeying spoken instructionsD. they can’t understand and obey the adult’s oral instructions42. Children who start speaking late ________.A. may have problems with their listeningB. probably do not hear enough language spoken around themC. usually pay close attention to what they hearD. often take a long time in learning to listen properly43. A baby’s first noises are ________.A. an expression of his moods and feelingsB. an early form of languageC. a sign that he means to tell you somethingD. an imitation of the speech of adults44. The problem of deciding at what point a baby’s imitations can be considered as speech________.A. is important because words have different meanings for different peopleB .is not especially important because the changeover takes place graduallyC. is one that should be properly understood because the meaning of words changes with ageD. is one that should be completely ignored（忽略）because children’s use of words is often meaningless45. The speaker implies________.A. parents can never hope to teach their children new soundsB. children no longer imitate people after they begin to speakC. children who are good at imitating learn new words more quicklyD. even after they have learnt to speak, children still enjoy imitating四．书面表达国外某网站将举办新一轮网上讨论活动，正面向全球中学生征集话题。

Unit4 拓展类文阅读1. Read about the general introduction of black hole.What is a black hole?A black hole is a region of spacetime from which nothing can escape, even light.To see why this happens, imagine throwing a tennis ball into the air. The harder you throw the tennis ball, the faster it is travelling when it leaves your hand and the higher the ball will go before turning back. If you throw it hard enough it will never return, the gravitational attraction will not be able to pull it back down. The velocity(速度) the ball must have to escape is known as the escape velocity and for the earth is about 7 miles a second.As a body is crushed into a smaller and smaller volume, the gravitational attraction increases, and hence(因此) the escape velocity gets bigger. Things have to be thrown harder and harder to escape. Eventually a point is reached when even light, which travels at 186 thousand miles a second, is not travelling fast enough to escape. At this point, nothing can get out as nothing can travel faster than light. This is a black hole.2. Collect as much information as possible about astronomy, Issac Newton, Albert Einstein, Stephen Hawking, and some other astronomers, especially about their ideas on gravity.1/ 1。
