老舍《养花》英译赏析老舍《养花》英译赏析珍贵的花草不易养活,看着一棵好花生病欲死是件难过的事。
下面是店铺精心整理的老舍《养花》英译赏析,仅供参考,欢迎大家阅读。
养花On Growing Flowers老舍Lao She我爱花,所以也爱养花。
我可还没成为养花专家,因为没有工夫去作研究与试验。
我只把养花当作生活中的一种乐趣,花开的大小好坏都不计较,只要开花我就高兴。
在我的小院中,到夏天,满是花草,小猫儿们只好上房去玩耍,地上没有它们的运动场。
I love flowers and hence have taken to growing them. But, short of time to do research and experiment in flower cultivation, I am no gardener at all. I merely take flower cultivation as a pleasure of life. I really don’t care whether or not my flowers will put forth plump and nice-looking blossom. I’ll be delighted as long as they can blossom. In summer, flowers and plants growing in luxuriance in my small courtyard will leave little open space as a playground for the little cats, so they have to sport about in our rooms instead.要点:1、先说标题,此处并没有单纯译为Growing flowers,而是加了on(此处表“关于”),因为本文并不单单是说养花这家事情,而是通过写“养花”表达自己对于知识的重视。

OverviewThere are more than 275,000 species of plants, and no one species can be used as a "typical example" of their body plans. Plants live in fresh water, in seawater, on land, even high above a forest floor (attached to other plants), and their features are correspondingly diverse. In size alone, plants range from microscopic algae to giant redwoods. Which plants, then, should be our focus? Botanists divide the plant kingdom into two broad categories:Vascular plants: with well-developed conducting tissues through which water andsolutes are transported to different body regions.Nonvascular plants: no internal transport systems (very simple ones).Because fewer than 30,000 species (the red, brown, and green algae and the bryophytes) are nonvascular, it is clear that the vascular pattern is more typical. The most familiar vascular plants are the seed-producing plants, so called spermatophyte and generally divided into gymnosperms and angiosperms:Gymnosperms: chiefly conifers, such as pines, spruces, firs, hemlocks, larches, cypress, junipers, maidenhair trees, and redwoods.Angiosperms: flowering plant s, such as poplars, willows,birches, walnuts, elms,mulberries, oaks, roses, apple trees, cherry trees, lilacs, lilies, tulips,orchids, and bamboos.The overwhelming majority of vascular plants (235,000 species) are flowering, and they will be our focus here. All vascular plants have primary tissues originating at roots and shoot tips, and as these tissues grow and develop, the roots, stems, and leaves increase in length. Collectively, these tissues are called primary growth. Many species also show secondary growth, which results in increases in diameter(girth,周长,围长) at older root and stem regions. For example,secondary growth adds to the woody parts of a maple tree; primary growth gives rise to its new shoots each spring.There are two classes of flowering plants, referred to informally as monocots and dicots. They both have a shoot system, consisting of stems and leaves, and a root system. Both produce flowers, which serve as the reproductive system. However, one of the main differences between the two classes is that monocot seeds have one cotyledon, and dicot seeds have two. Other differences between monocots and dicots are shown as follows:Monocots Dicotsone cotyledon in seed two cotyledons in seedfloral parts usually occur in threes floral parts usually occur in fivesleaf veins usually are parallel leaf veins usually are netlikemost monocots show little or many dicots show secondary growthno secondary growthpollen grains basically have one pore pollen grains basically have three pore or furrows or furrowsAn Overview of Common Plants种子植物Spermatophyte 裸子植物Gymnosperms 被子植物Angiosperms 双子叶植物Dicotyledons 单子叶植物monocotyledons松属pine 冷杉属fir云杉属spruce 落叶松属larch铁杉属hemlock 银杏maidenhair tree, Ginkgo 雪松cedar金松golden larch 杉木Chinese fir 北美红杉sequoia, R edwood巨杉Giant sequoia, giant redwood, Big-Tree 水杉metasequoia, fossil tree红豆杉yew 三尖杉属plum-yew 榧树属torreya扁柏属cedar 刺柏属juniper 柏木属cypress侧柏属Chinese thuja, Oriental Arbor-Vitae 圆柏属juniper柳属willow, osier, salon-tree 杨属poplar, cotton wood, aspen山毛榉,水青冈beech 锥栗属,栗属chestnut 栎属oak桤木,赤杨alder 桦木属birch 鹅耳枥属hornbeam铁木属hop-hornbeam 榛属hazel (tree) 榆属elm朴树属hack-berry, nettle-tree 桑属mulberry 构树paper-mulberry榕树属fig-tree 无花果fig 胡桃属walnut山核桃hickory 枫杨wing-nut 榛属nut-tree芍药属peony(牡丹tree peony)小檗属berbery 木兰属magnolia鹅掌楸tulip-tree 悬铃木plane(tree)漆树属sumac (h )槭树属maple 蔷薇属rose 树莓(悬钩子)属,dewberry 苹果apple tree 李子plum 梨pear樱桃cherry 杏apricot 桃peach山楂haw, hawthorn 梅plum 花楸属sorb, service-tree, scorb 绣线菊属meadow sweet 金合欢wattle刺槐locust 皂荚属honey-locust 胡枝子属bush-clover臭椿tree of heaven 楝树China-tree 卫矛属spindle tree南蛇藤staff-tree 冬青属holly 黄杨属box黄栌smoke-tree 茉莉属jasmine 桉树gum椴树属basswood, lime, linden 七叶树属horse chestnut 柿树属persimmon, ebony鼠李属buckthorn 枣树common jujube 葡萄grape柽柳属tamarisk 茶树tea 石榴pomegranate珙桐dove-tree 梾木dogwood 常春藤ivy杜鹃花属azalea 丁香属lilac, clove 白蜡属ash连翘golden-bell 桂花fragrant flower 楸树catalpa, bean-tree柚pomelo, pum [m]elo 柠檬树,橙lemon tree 柑桔(橘)orange忍冬属honeysuckle 枸杞boxthorn 竹类bamboo亚麻flax 草莓strawberry 郁金香tulip百合lily 兰orchid 人参ginseng。
关于种花草使校园更美的英语作文的英语作全文共5篇示例,供读者参考篇1Planting Flowers and Plants to Make Our School Look Amazing!Hi there! My name is Emma and I'm a student at Sunnydale Elementary School. I really love our school, but I think there's something we could do to make it look even better – we should plant lots of beautiful flowers and plants all around!Have you ever noticed how pretty gardens and parks with lots of colorful flowers look? They're so bright and cheerful. Wouldn't it be awesome if our schoolyard looked like that too? Just imagine walking through the gates in the morning and being greeted by tons of roses, tulips, daffodils and other gorgeous flowers everywhere you look. How amazing would that be?Not only would it make our school grounds way more attractive, but plants and flowers also provide homes for all sorts of cool critters like birds, butterflies and ladybugs. We'd get to see them fluttering and crawling around while we play outside atrecess. Plus, plants and flowers make the air fresher and cleaner for us to breathe. How neat is that?I've been dreaming of this idea for a while now, and I've done some research on how we could actually make it happen. First, we'd need to get permission from the principal and teachers. I'm sure they'd be on board though, since a beautiful flowery schoolyard would put smiles on everyone's faces. It might even attract more students to want to come to our awesome school!Next, we'd need lots of supplies like soil, seeds, bulbs, gardening tools and maybe even some small trees or bushes to plant. I'll bet we could get donations of those things from local gardening stores or nurseries if we explain what a cool project this is. We could also ask parents to donate any extra gardening supplies they have at home and don't need.Once we have all the materials, we'd need to figure out the best sunny and shady spots around the schoolyard to plant everything. The front areas along the sidewalks and fences would be perfect for tall, bright flowers that would grab people's attention as they walk by. Maybe we could put flowering bushes and trees along the edges too. Then in the big grassy areas, wecould make flowerbeds bursting with loads of different colorful flowers and plants.Maintaining all of the new gardens would be a lot of work, but I know we students could totally handle it. We could form "Green Teams" and each team could be responsible for certain garden areas. We'd need to water the plants, pull out any weeds, replant anything that dies, and gently prune and trim the bushes and trees as needed. Older students could even teach the younger kids about botany and ecology.Just thinking about how unbelievably pretty and lively our campus would look with tons of vibrant flowers and plants has me super excited! Imagine students feeling happy and calm while reading or eating lunch surrounded by beautiful gardens. Picture families taking photos at our school with the gorgeous flowery backgrounds. Our whole community would be proud of our stunning, blooming schoolyard.We'd probably need to start small at first and just get a few garden areas planted and established. But year after year, we could expand bit by bit with more flower beds, bushes and trees until the whole campus looks like a ecological paradise! A place that's not only amazing for learning, but also a feast for the eyes and soul.What do you think? Are you just as pumped as I am about this idea to make our school look like a wonderland of flowers and plants? We'd have the most beautiful campus in the whole city, maybe even the state! If everyone -- students, staff, parents and community members -- teamed up, I really believe we could make this dream a reality. Our school deserves to look absolutely phenomenal. So let's get started getting those green thumbs ready for some serious gardening!篇2Making Our School Beautiful with Flowers and GrassHi, my name is Jamie and I'm a student in the 5th grade. Today, I want to talk about how we can make our school look even more amazing by planting flowers and grass around the campus. It's such a fun and easy way for kids like us to get involved and make a big difference!First of all, let me tell you why I think this is such a great idea. Our school is already really nice, with lots of open space for us to run around and play during recess. But you know what would make it even better? Splashes of color from pretty flowers and lush, green grass covering some of those bare areas. It wouldturn our school into a vibrant, living garden that's just bursting with life and beauty.Imagine walking through the main entrance in the morning and being greeted by rows of sunflowers standing tall, their yellow petals reaching up to greet the sun. Or picture relaxing under a shady tree during lunch, surrounded by bushes covered in pink and white roses. How peaceful and relaxing would that be?And let's not forget about grass! Having grassy areas for us to sit, play, and even learn outdoors would be awesome. We could have reading circles on the grass, or our gym teacher could take us outside for exercises and games. Grass also helps prevent soil erosion and reduces dust in the air, which is much healthier for us.Speaking of health, there are so many benefits to being around flowers, trees, and nature. Studies show that having plants around can improve our moods, reduce stress and anxiety, and even help us concentrate better in class. Just looking at something pretty like a garden can make us feel happy and calm inside. Plus, the flowers would attract bees, butterflies, and other cool critters for us to observe.Now, I know what you might be thinking – how can kids like us possibly transform our whole school into a garden? Well, with a little teamwork and some helping hands from teachers and parents, it's totally possible! We can start small by planting flower beds along the main walkways or around the school buildings. Once those get established, we can look into adding more throughout the campus.We'll need to research which types of plants grow best in our local climate. Luckily, there are lots of beautiful options like roses, daffodils, tulips and many others that would look gorgeous here. For grass, we may want a variety that's drought-resistant since we live in a dry area. Getting expert advice from a gardener or the local nursery will really help.Of course, gardens need lots of care and hard work from all of us students. We'll have to take turns watering the plants, pulling weeds, and maybe even building some decorative items like bird houses to add around the gardens. But I know we can do it if we all pitch in!Just imagine how proud we'll feel looking out at the stunning gardens we created together. Our school will be the prettiest one around, with fotografers coming from miles away to take pictures of it. And whenever we see those colorful flowersor run around on the soft grass, we'll know that we helped make that beauty happen. How awesome is that?So what do you say? Are you ready to get your hands dirty and turn our campus into a living work of art? Let's grab our gardening gloves and get planting! With a little hard work and a lot of care, our school will be even more special than it already is. We've got this, gardeners!篇3My School GardenHi! My name is Emma and I'm in 5th grade. I love my school, but I think we could make it look even prettier by planting some flowers and plants around the buildings and playground. Having a nice garden would make our school so colorful and inviting. Let me tell you all about my idea!First of all, I think we should have flower beds along the front of the school near the entrance. When people first come to our school, it would look so cheerful and welcoming if there were lots of bright flowers blooming there. We could plant tulips, daffodils, roses, sunflowers and more. The red, yellow, pink and purple flowers would be so vibrant and beautiful.Next, we need to put some flowery plants and shrubs around the edges of the playground area. That way, when we're playing at recess, we'll be surrounded by pretty blooms and green leaves. I'm imagining azaleas, hydrangeas, lilies and rhododendrons planted in the playground gardens. Their petals would sway gently in the breeze as we run around. Wouldn't that be delightful?We could also line the sidewalks and paths around school with flower beds too. Students and teachers could enjoy the floral scenery as they walk along. Lining the paths with marigolds, zinnias, petunias and impatiens would surely put a smile on everyone's face each day.Oh, and we can't forget about planting some things in big colorful pots and planters too! We could put those flowering potted plants right outside the main entrance and along the pick-up and drop-off areas for cars. Red geraniums, purple wave petunias and yellow marigolds would make such a pretty entrance display.In addition to flowers, we could also plant some trees, shrubs and other plants around the school grounds to make it look green and lush. Imagine climbing oaks, blossoming cherry trees, neatly trimmed bushes and plants with different colored leavesand textures. It would be like a miniature park right at our school!Having a botanical garden around our school would do so much more than just make it look nicer too. We could use the garden areas for science lessons about plants, insects, butterflies and more. How awesome would it be to see butterflies and bees fluttering around our flower beds? The garden could also attract pretty birds that we could birdwatch and learn about.Other classes could use the gardens for inspiration too. The art students could paint or sketch the flowers and plants. The writers could go sit among the blooms and trees to help them feel creative and inspired as they write their stories and poems. During quiet reading time, kids could pick a garden spot to relax and unwind with their books.For kids who don't have a yard or garden at home, the school garden would allow them to experience nature up close. They could see plants and flowers go through their life cycles as the seasons change. In the spring, they'd witness buds opening into colorful blooms. During summer, the plants would be in full bloom with vibrant colors. In fall, leaves would change into radiant oranges, reds and yellows before dropping off in winter. What an amazing science lesson just from planting flowers!I think having a big flower and plant garden at school would also make us all feel happier in general. The bright colors are sure to lift our moods and spirits each day. When I'm having a hard day, looking at a vase of fresh cut flowers from the school gardens always seems to cheer me up. Flowers and plants have a way of allowing us to relax and destress from our worries. Taking a few deep breaths while surrounded by the peaceful scenery and fragrances of the gardens could help us refocus too.Creating a flower and plant garden at our school would take some hard work, but it would be so worth it! We students could help with planting everything. Our parents and teachers might want to volunteer to help take care of the gardens too by doing things like watering, weeding, pruning and raking. Local garden clubs or nurseries might even be willing to donate some plants, tools or gardening advice. Once it's all planted and growing, the entire school community could take pride in maintaining the gardens together.In conclusion, putting in a flower and plant garden at our school would make it look and feel like a true outdoor wonderland. We'd have a cheerful, tranquil oasis right on our campus. The garden would allow us to experience the beauty of nature's colors and cycles. It would attract pretty wildlife likebutterflies and birds. Our garden areas would even provide beautiful backdrops for learning about science, art and writing. Most of all, being surrounded by lush gardens would instantly put us all in a better mood each day. A garden is definitely what our school needs to go from boring to breathtaking! What does everyone think? Should we start planting?篇4Making Our School Look Prettier with Flowers and PlantsHi there! My name is Emma and I'm in 5th grade. I love my school, but I think it could look even nicer if we had more flowers and plants around. Let me tell you why I think we should plant more and how we can make our campus bloom!First of all, flowers are just so pretty to look at. They come in tons of different colors like red, yellow, purple, pink, and more. Some have bright shades while others are more pale and delicate. Their petals can be shaped differently too - some look like trumpets, some are round like plates, and some even have frilly edges. With so many possibilities, we could make amazing rainbow flower beds and gardens.Not only are flowers colorful, but a lot of them smell wonderful too. Roses have a classic sweet scent, lavender smellsclean and relaxing, and honeysuckle always reminds me of summer. Having fragrant flowers around means our outdoor areas would have delightful natural perfumes instead of smelly smells.Plants are important too, not just flowers. We need trees to provide shade over our playgrounds and gardens. Shrubs placed around the buildings would make them look more welcoming. And herbs like mint, rosemary, and thyme could be used by the cafeteria for cooking!Speaking of the cafeteria, did you know some plants are edible too? We could plant fruits and veggies and use them for snacks and lunches. How cool would it be to have fresh strawberries, blueberries, carrots, and lettuce harvested right from our own gardens? Yum!Another awesome thing about plants is they help the environment. The leaves absorb carbon dioxide from the air and produce oxygen for us to breathe. More plants means more clean air for everyone. Plants also provide food and homes for lots of critters like birds, squirrels, butterflies, and bees. Our campus would be helping nature by giving wildlife a safe green space.But my favorite reason to add more plants is the simple fact that they're just fun to take care of! Getting a little dirty while digging holes and watering the plants can be such an adventure. There's a feeling of pride in nurturing something and watching it grow bigger and bigger. We could even make garden clubs or classes where kids learn aboutdifferent species and how to be greenthumbs.Of course, starting a big planting project takes some work. We would need tools like shovels, trowels, rakes, and hoses. Fertile soil, seeds, bulbs, and young plants would also need to be purchased. An area would have to be designated for the gardens, maybe between the school buildings or around the fields. We'd need volunteers - teachers, parents, and students - to help prep the land, do the planting, and care for everything as it grows.But I think it would be worth all the effort! Just imagine how pretty our campus would look covered in colorful flowers. The fresh air would be so nice to breathe and it would make a safe environment for animals too. Gardens could provide yummy food and fun hands-on lessons about nature. Having an inside greenhouse for colder months could make it a year-round activity. Our school would basically become a blossoming park!Making these kinds of changes wouldn't happen overnight though. We'd start small, maybe just planting a few flower beds first. Once we see how great it looks, we could slowly add more and more each year. A group of volunteers could take charge of the project and decide what areas to focus on updating next. Getting donations of plants, tools, and money from our community would really help make it grow too. Small steps can lead to big results if we work hard!I really hope I've convinced you that adding a lot more plants and flowers to our school grounds is a wonderful idea. We're so lucky to have a beautiful campus already, but it could be taken to the next level with gardens galore! Just think about how happy it would make everyone to be surrounded by so much pretty greenery. I know I would love looking at it every day. What's better than making our world a little more colorful and alive?Okay, I've said quite a lot, but I have one more tiny request...can I please be on the garden club if we make one? Getting my hands dirty while helping transform our school sounds like a dream! I'll be sure to take good care of any plants or flowers I'm responsible for. You can count on me to be our class's next great green thumb!Thank you for reading my essay. I hope you'll agree that plants are a fantastic way to naturally improve our campus. Our school could become a beautiful, breathtaking, blooming environment that makes everyone smile. Now let's grab some seeds and shovels and get growing!篇5Making Our School Look Awesome With Flowers and Plants!Hey everybody! I want to talk to you today about something that I think is really important for our school. It's about making our campus look prettier and more colorful by planting lots of beautiful flowers and cool plants everywhere. I'm sure you'll agree with me once I explain why it's such a great idea!First of all, flowers and plants are just so amazing to look at. They come in so many shapes, sizes and pretty colors. Can you imagine how much better our drab, boring school grounds would look if we had bunches of roses, tulips, sunflowers and other flowers blooming all over? It would be like a rainbow exploded everywhere! And plants with big leaves or neat shapes like ferns would make everything look so lush and jungle-like. Wouldn't that be awesome?Another reason we need more plants is because they literally make the air fresher and cleaner for us to breathe. Plants take in that bad carbon dioxide stuff that we exhale and then release nice oxygen that we need to live. So the more plants we have, the more fresh and healthy air we'll get to breathe instead of polluted air. Doesn't that sound great?You know what else is cool about plants? They provide homes and food for lots of amazing little critters like ladybugs, butterflies, hummingbirds and more. If we had a garden filled with flowers, bushes and trees, we could see all these fascinating insects and animals right on our campus! We could learn about how they live and grow. Isn't that way more fun than just reading about them from a book? I would love to help take care of a garden like that.Speaking of gardening, that's another reason why filling our campus with plants is an excellent idea - because it gives us a chance to learn about gardening! We could have a gardening club where we get our hands dirty by planting seeds, pulling weeds, watering the plants and watching them grow from tiny seedlings into big, mature flowering plants or trees. Gardening teaches us so many important life skills like responsibility,patience, hard work and more. Plus it's just super fun to see the plants you've tended yourself sprout up from the earth!I'm sure some of you are probably thinking - plants, schmants, who cares? Flowers and stuff are boring! To those kids, I'll just point out that having a pretty campus landscaped with colorful flowers, lush green plants, elegant trees and a garden area is going to make our school look approximately one million times more amazing. All the other schools that are just dull, barren places will be totally jealous. Our school will hands-down be the prettiest and coolest one in the entire area if we make it a green, blossoming paradise!And finally, having a beautiful campus environment with lots of flowers, trees and other plants will just make us feel happier overall. Scientific studies show that being around plants and nature improves people's moods and concentration. So we'll all be more relaxed, focused and cheerful when we get to spend time surrounded by pretty greenery every day at school. Does that sound nice or what?In conclusion, I think we absolutely need to start planting way more flowers, trees, bushes, plants and maybe even start a little garden area at our school. Not only will it make our campus look 100 times more gorgeous, colorful and inviting, but it willalso help clean the air, attract cool critters, teach us gardening skills and just make us all happier overall. Who wouldn't want all of that amazingness? Let's make our school a true bloomin' paradise by adding more beautiful plants ASAP! We'll instantly have the most stunning, jaw-dropping campus that everyone wishes they could call their school. So let's get growing!。

As I have observed various flowers and plants over time, I have come to appreciate the intricate process of their growth.One of the most interesting aspects of observing the growth of flowers and plants is witnessing the different stages they go through. For example, a seedling starts as a tiny, fragile sprout that pushes through the soil. It then begins to develop leaves and stems, gradually growingtaller and stronger. Eventually, it blossoms into a beautiful flower with vibrant colors and a delicate fragrance.The growth of flowers and plants is influenced by various factors, including sunlight, water, and nutrients.Sunlight is essential for photosynthesis, a process through which plants convert sunlight into energy. Water is necessary for the transportation of nutrients and minerals, as well as for maintaining turgidity. Nutrients, such as nitrogen, phosphorus, and potassium, are vital for the overall health and growth of plants.In addition to these external factors, the growth of flowers and plants also depends on their genetic makeup. Each species has its own unique characteristics and requirements. For example, some plants thrive in shady areas, while others prefer direct sunlight. Some flowers require specific soil conditions, while others can adapt to a wide range of environments.It is fascinating to witness how flowers and plants adapt to their surroundings. They have a remarkable ability to respond to changes in their environment. For instance, some plants have mechanisms to conserve water during droughts, while others have developed thorns or toxins to protect themselves from predators. These adaptations ensure their survival and enable them to thrive in variousecosystems.中文回答:观察花草的成长是一种迷人的体验。
