英语是国际经济、技术、信息等交流中应用最广泛的语言，下面就是我给大家整理的英文小 文章 ，希望大家喜欢。英文小文章：爱如鲜花盛开 I was nine when my father first sent me flowers. I had been taking tapdancing(踢踏舞) lessons for six months, and the school was giving its yearly recital. As an excited member of the beginners' chorus line, I was aware of my lowly status. So it was a surprise to have my name called out at the end of the show along with the lead dancers and to find my arms full of long-stemmed red roses. I can still feel myself standing on that stage, blushing furiously and gazing over the footlights to see my father's grin as he applauded loudly. Those roses were the first in a series of large bouquets(花束，宴会) that accompanied all the milestones in my life. They brought a sense of embarrassment. I enjoyed them, but was flustered by the extravagance. Not my father. He did everything in a big way. If you sent him to the bakery for a cake, he came back with three. Once, when Mother told him I needed a new party dress, he brought home a dozen. His behavior often left us without funds for other more important things. After the dress incident, there was no money for the winter coat I really needed--or the new ice skates I wanted. Sometimes I would be angry with him, but not for long. Inevitably he would buy me something to make up with me. The gift was so apparently an offering of love he could not verbalize that I would throw my arms around him and kiss him--an act that undoubtedly perpetuated(保持) his behavior. Then came my 16th birthday. It was not a happy occasion. I was fat and had no boyfriend. And my well-meaning parents furthered my misery by giving me a party. As I entered the dining room, there on the table next to my cake was a huge bouquet of flowers, bigger than any before. I wanted to hide. Now everyone would think my father had sent flowers because I had no boyfriend to do it. Sweet 16, and I felt like crying. I probably would have, but my best friend, Phyllis, whispered, "Boy, you're lucky to have a father like that. As the years passed, other occasions--birthdays, recitals(朗诵), awards, graduations--were marked with Dad's flowers. My emotions continued to seesaw between pleasure and embarrassment. When I graduated from college, though, my days of ambivalence(矛盾情绪) were over. I was embarking on a new career and was engaged to be married. Dad's flowers symbolized his pride, and my triumph. They evoked only great pleasure. Now there were bright-orange mums for Thanksgiving and a huge pink poinsettia at Christmas. White lilies at Easter, and velvety red roses for birthdays. Seasonal flowers in mixed bouquets celebrated the births of my children and the move to our first house. As my fortunes grew, my father's waned, but his gifts of flowers continued until he died of a heart attack a few months before his 70th birthday. Without embarrassment, I covered his coffin with the largest, reddest roses I could find. Often in the dozen years since, I felt an urge to go out and buy a big bouquet to fill the living room, but I never did. Often in the dozen years since, I felt an urge to go out and buy a big bouquet to fill the living room, but I never did. I knew it would not be the same. Then one birthday, the doorbell rang. I was feeling blue because I was alone. My husband was playing golf, and my two daughters were away. My 13-year-old son, Matt, had run out earlier with a "see you later," never mentioning my birthday. So I was surprised to see his large frame at the door. "Forgot my key," he said, shrugging. "Forgot your birthday too. Well, I hope you like flowers, Mum." He pulled a bunch of daisies from behind his back. "Oh, Matt," I cried, hugging him hard. "I love flowers!" 英文小文章：适应力的 故事 Don't worry if you have problems! Which is easy to say until you are in the midst of a really big one, I know. But the only people I am aware of who don't have troubles are gathered in little neighborhoods. Most communities have at least one. We call them cemeteries(墓地). If you're breathing, you have difficulties. It's the way of life. And believe it or not, most of your problems may actually be good for you! Let me explain. Maybe you have seen the Great Barrier Reef, stretching some 1,800 miles from New Guinea to Australia. Tour guides regularly take visitors to view the reef. On one tour, the guide was asked an interesting question. "I notice that the lagoon(环礁湖) side of the reef looks pale and lifeless, while the ocean side is vibrant and colorful," a traveler observed. "Why is this?" The guide gave an interesting answer: "The coral around the lagoon side is in still water, with no challenge for its survival. It dies early. The coral on the ocean side is constantly being tested by wind, waves, storms -- surges of power. It has to fight for survival every day of its life. As it is challenged and tested, it changes and adapts. It grows healthy. It grows strong. And it reproduces." Then he added this telling note: "That's the way it is with every living organism." That's how it is with people. Challenged and tested, we come alive! Like coral pounded by the sea, we grow. Physical demands can cause us to grow stronger. Mental and emotional stress can produce tough-mindedness and resiliency. Spiritual testing can produce strength of character and faithfulness. So, you have problems -- no problem! Just tell yourself, "Here I grow again " 英文小文章：放弃是一种美丽 One of tests used by a company to enroll fresh blood helps you know whether you stand the trial from yourself. In a stormy night, you drive your car through a stop where three people are waiting for a bus: a dying and poor old man, a doctor who is your benefactor(恩人) because he saved your life so that you are eager to render back, and a woman or a man who is your dreamgirl or your dreamboy and likely dissapears from your life once you miss the chance. Unfortunately, there is just room for one person in your car. Which one would you pick up? Then give your reasons. Think it over before looking at the following text. I have no idea whether it is a characteristic test, because every answer has its reason. The dying old man should be first helped,however, his final destination is death. It's reasonable for you to pick up the doctor first--your benefactor and is a good chance to reciprocate(报答，互换) what he did for you. Meanwhile, some people think it available to render the doctor back in someday in future. And if you miss the chance, you will never meet such an attractive person. Only one of two hundred people was hired. He wrote his answer without providing his reason: "Give the key of my car to the doctor, and let him take the old man to the hospital. But I wait in the stop for the bus with my dreamboat(梦中人，爱人) together." Every acquaintance of mine regarded it as the best answer but nobody (including me) realized it at first. It is caused by our idea of not giving up the advantage (the car key) we have had? Sometimes, if we abandon some of our parochialism(狭隘), advantages, and intransigence(不妥协), we can get more.
英语作为一门国际通用语,在21世纪已经向着多元化、多功能化的方向发展。下面就是我给大家整理的短小的英语 文章 ，希望大家喜欢。短小的英语文章：The art of living What is it like to be old in the United States? What will our own lives be like when we are old? Americans find it difficult to think about old age until they are propelled into the midst of it by their own aging and that of relatives and friends. Aging is the neglected stepchild of the human life cycle. Though we have begun to examine the socially taboo subjects of dying and death, we have leaped over that long period of time preceding death known as old age. In truth, it is easier to manage the problems of death than the problem of living as an old person. Death is a dramatic, one-time crisis while old age is a day-by-day and year-by-year confrontation with powerful external forces, a bittersweet coming to terms with one's own personality and one's life. Old age is neither inherently miserable nor inherently sublime-like every stage of life it has problems, joys, fears and potentials. The process of aging and eventual death must ultimately be accepted as the natural progression of the life cycle, the old completing their prescribed life spans and making way for the young. Much that is unique in old age in fact derives from the reality of aging and the imminence of death. The old must clarify and find use for what they have attained in a lifetime of learning and adapting they must conserve strength and resources where necessary and adjust creatively to those changes and losses that occur as part of the aging experience. The elderly have the potential for qualities of human reflection and observation which can only come from having lived an entire life span. There is a lifetime accumulation of personality and experience which is available to be used and enjoyed. But what are an individual's chances for a "good" old age in America, with satisfying final years and a dignified death? Unfortunately , none too good. For many elderly Americans old age is a tragedy, a period of quiet despair, deprivation , desolation and muted rage. This can be a consequence of the kind of life a person has led in younger years and the problems in his or her relationships with others. There are also inevitable personal and physical losses to be sustained, some of which can become overwhelming and unbearable. All of this is the individual factor, the existential element. But old age is frequently a tragedy even when the early years have been fulfilling and people seemingly have everything going for them. Herein lies what I consider to be the genuine tragedy of old age in America -- we have shaped a society which is extremely harsh to live in when one is old. The tragedy of old age is not the fact that each of us must grow old and die but that the process of doing so has been made unnecessarily and at times excruciatingly painful, humiliating, debilitating and isolating through insensitivity, ignorance and poverty. The potentials for satisfactions and even triumphs in late life are real and vastly under explored. For the most part the elderly struggle to exist in an inhospitable world. 短小的英语文章：The lowest animal Man is the only animal that robs his helpless fellow of his country-takes possession of it and drives him out of it or destroys him. Man has done this in all the ages. There is not an acre of ground on the globe that is in possession of its rightful owner, or that has not been taken away from owner after owner, cycle after cycle, by force and bloodshed. Man is the only Slave. And he is the only animal who enslaves. He has always been a slave in one form or another, and has always held other slaves in bondage under him in one way or another. In our day he is always some man's slave for wages, and does the man's work; and this slave has other slaves under him for minor wages, and they do his work. The higher animals are the only ones who exclusively do their own work and provide their own living. Man is the only Patriot. He sets himself apart in his own country, under his own flag, and sneers at the other nations, and keeps multitudinous uniformed assassins on hand at heavy expense to grab slices of other people's countries, and keep them from grabbing slices of his. And in the intervals between campaigns he washes the blood off his hands and works for "the universal brotherhood of man"-with his mouth. Man is the Religious Animal. He is the only Religious Animal. He is the only animal that has the True Religion-several of them. He is the only animal that loves his neighbor as himself, and cuts his throat if his theology isn't straight. He has made a graveyard of the globe in trying his honest best to smooth his brother's path to happiness and heaven. He was at it in the time of Caesars, he was at it in Mahomet's time, he was at it in the time of the Inquisition, he was at it in France a couple of centuries, he was at it in England in Mary's day, he has been at it ever since he first saw the light, he is at it today in Crete-as per the telegrams quoted above*-he will be at it somewhere else tomorrow. The higher animals have no religion. And we are told that they are going to be left out, in the Hereafter. I wonder why? It seems questionable taste. Man is the Reasoning Animal. Such is the claim. I think it is open to dispute. Indeed, my experiments have proven to me that he is the Unreasoning Animal. Note his history, as sketched above. It seems plain to me that whatever he is he is not a reasoning animal. His record is the fantastic record of a maniac. I consider that the strongest count against his intelligence is the fact that with that record back of him he blandly sets himself up as the head animal of the lot: whereas by his own standards he is the bottom one. In truth, man is incurably foolish. Simple things which the other animals easily learn, he is incapable of learning. Among my experiments was this. In an hour I taught a cat and a dog to be friends. I put them in a cage. In another hour I taught them to be friends with a rabbit. In the course of two days I was able to add a fox, a goose, a squirrel and some doves. Finally a monkey. They lived together in peace; even affectionately. 短小的英语文章：Living a solitary life The other day an acquaintance of mine, a gregarious and charming man, told me he had found himself unexpectedly alone in New York for an hour or two between appointments. He went to the Whitney and spent the "empty" time looking at things in solitary bliss. For him it proved to be a shock nearly as great as falling in love to discover that he could enjoy himself so much alone. What had he been afraid of, I asked myself? That, suddenly alone, he would discover that he bored himself, or that there was, quite simply, no self there to meet? But having taken the plunge, he is now on the brink of adventure; he is about to be launched into his own inner space to the astronaut. His every perception will come to him with a new freshness and, for a time, seem startlingly original. For anyone who can see things for himself with a naked eye becomes, for a moment or two, something of a genius. With another human being present vision becomes double vision, inevitably. We are busy wondering, what does my companion see or think of this, and what do I think of it? The original impact gets lost, or diffused. "Music I heard with you was more than music." Exactly. And therefore music itself can only be heard alone. Solitude is the salt of personhood. It brings out the authentic flavor of every experience. "Alone one is never lonely: the spirit adventures, walking in a quiet garden, in a cool house, abiding single there." Loneliness is most acutely felt with other people, for with others,even with a lover sometimes, we suffer from our differences of taste, temperament,mood. Human intercourse often demands that we soften the edge of perception, or withdraw at the very instant of personal truth for fear of hurting, or of being inappropriately present, which is to say naked, in a social situation. Alone we can afford to be wholly whatever we are, and to feel whatever we feel absolutely. That is a great luxury! For me the most interesting thing about a solitary life, and mine has been that for the last twenty years, is that it becomes increasingly rewarding. When I can wake up and watch the sun rise over the ocean, as I do most days, and know that I have an entire day ahead, uninterrupted, in which to write a few pages, take a walk with my dog, lie down in the afternoon for a long think (why does one think better in a horizontal position?), read and listen to music, I am flooded with happiness. I'm lonely only when I am overtired, when I have worked too long without a break, when from the time being I feel empty and need filling up. And I am lonely sometimes when I come back home after a lecture trip, when I have seen a lot of people and talked a lot, and am full to the brim with experience that needs to be sorted out. Then for a little while the house feels huge and empty, and I wonder where my self is hiding. It has to be recaptured slowly by watering the plants and perhaps,by looking again at each one as though it were a person. It takes a while, as I watch the surf blowing up in fountains at the end of the field, but the moment comes when the world falls away, and the self emerges again from the deep unconscious, bringing back all I have recently experienced to be explored and slowly understood, when I can converse again with my hidden powers, and so grow, and so be renewed, till death do us part.
