关于发明英语演讲稿3分钟 篇1what is my favorite invention?
we knew there had been many inventions at the last century, for example,electric light bulb, telephone, phonograph, mimeograph machine, automobile,airplane, atomic weapon, computer and so on. what is my favorite invention?
personally, my favorite invention should be computer. in the old days, manyscientists took much time to calculate and deal with research data, so theeffective time in doing research was relatively shortened. for millions of timesof calculating per second by computer, the researchers may have enough time tostudy more important issues. the processing of experiment results became verysimple and easy. aren’t those all evidences that the computer is one of thegreatest inventions in the last century, are those?
so my favorite invention is computer.
关于发明英语演讲稿3分钟 篇2When I was a child, I was always dreaming of what I could become when Igrew up. Become a singer? Become a painter? Become an actor? These are someglamorous professions, and what I want to be the most is an inventor.
Although the inventor is a behind-the-scenes worker, he can make a greatcontribution to human development. It can make people's lives less tired andmake people happier every day.
If I were an inventor, I would invent many things that would be convenientfor people to live on. Start with people's housing starts! If I were aninventor, I would invent a very advanced door. The shape of this door is notdifferent from the ordinary one, but it has many functions. First of all, whenthe noise coming from the corridor, the door can be according to the master'svoice as he opened the door ahead of time, when the owner came to the door itsay: "master, welcome home!" Then the door closes. The advantage of this designis that the owners no longer have to go out with keys. Second, if there is a badguy to destroy the door, the door have a security alarm system, can let theneighbors know there is a thief, the thief will soon be away. And the door willalso send the information to the owner's mobile phone for the first time,telling the host that there is a bad guy and need to deal with it as soon aspossible. Finally, the door has the function of weather forecasting. At seven o'clock in the morning, it will report on time and report the weather and thesituation of the day. If the weather forecast says it's going to rain, the doorwill offer an umbrella before its owner goes out, and if it's a big summer itwill also offer a sunblock and sunscreen. The invention guarantees home safety,improves living standards and makes people's lives more comfortable.
If I were an inventor, I wanted to invent a medicine that would delaypeople's life slightly. Because I know that it is impossible to live forever,and if you can live forever, there will be more and more people in the world. Aslight delay is the ability to make a person's life a little longer. Theinvention is mainly used for the immediate death of the hospital, but to thepeople who want to see the last of their loved ones. Or people who are in a caraccident or other sudden death. Because of this invention, they can be able tosee the last part of their family, leaving them with the words they want to say,without regret.
If I were an inventor, I would invent an emotional robot. Scientists sayrobots are mechanical, unemotional and can't understand what people really need.And I'm going to invent this robot, which has its own personality, apart frombeing able to do the housework, the laundry, the cooking. Owners can chooserobots with different personalities.
There are gentle, considerate, or tyrants. The charm value of the robot canbe acquired by itself. At that time, the robot is more than just a machine, itcan be your family, your friends, more like your child. He's hungry and needsyou to feed him. When you are sad it will hug you, stand beside you and comfortyou and tell you jokes. When you're nervous, it encourages you and tells youit's ok. When you are happy, it will give you all kinds of celebrations,standing next to you and dancing, more than you are happy. But the baby robotalso dies, for example, when it dies of starvation, or parts that are too longand die. But you can rest assured that the life of the robot baby is usually ahundred years old, enough to accompany you forever.
If I am the inventor, I would also like to invent a lot of things tobenefit mankind, I'm not in order to let everyone thank me, let me earn a lot ofmoney, but in order to let people all over the world have a safe, happy, happy,carefree, so I am very satisfied. I would like to be an inventor. For thisdream, I must study hard and go to a good university in the future. I can getrid of the word "if" and realize my dream.

关于发明英语演讲稿3分钟 篇6ladies and gentlemen, teachers, my fellow students:
i am very excited and feel it's a great honor to stand here to deliver my speech. what i'm going to talk about is “choice in my life”
i can still remember the first time i failed in a singing contest. i immediately ran to my grandma, shedding lots of tears of course! i cried loudly and could hardly utter a word!
then, badly needed comforting words and touch came from grandma. i gradually regained my sense of pride and a sensible control of my feelings. yet, head down, i said: “grandma, i have no choice, and i have to give up, right?” “look at me, my dear!”she said gently. i looked up, straight into her eyes. what i saw was a shining, sweet, and loving stream from the bottom of her heart! then, there came the gentle voice of hers: “no, no, no…” her head shaking, while eyes smiling. “why don't you give more attention to the details?” she continued.
no other words were needed any more! i started practicing and rehearsing once again, paying special attention to those little things that i used to ignore. as a consequence, my overall performance was quickly elevated to a new high! without much trouble, in another singing contest held months later, i won!
what do i learn from this experience? never give up lightly! life's full of opportunities, and lots of them! to realize your dreams and fulfill your potential, you must learn to work hard and smart and steer your lifeboat wisely! as a li ling's sportswear commercial goes “everything is possible!” but not without sweat, devotion, and tears sometimes!
life is a long journey, during which we are surely going to face many challenges, experience lots of failures, and equally, many opportunities are waving to us, while sweet rewards are waiting for us! to transform these opportunities into fruitful results, or turn those challenges and failures into valuable assets, we must learn to seize the good ones and not to retreat lightly in front of difficulties.
winners can never be quitters!
thank you all!
关于发明英语演讲稿3分钟 篇7five score years ago, a great american, in whose symbolic shadow we stand signed the emancipation proclamation. this momentous decree came as a great beacon light of hope to millions of negro slaves who had been seared in the flames of withering injustice. it came as a joyous daybreak to end the long night of captivity.
but one hundred years later, we must face the tragic fact that the negro is still not free. one hundred years later, the life of the negro is still sadly crippled by the manacles of segregation and the chains of discrimination. one hundred years later, the negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. one hundred years later, the negro is still languishing in the corners of american society and finds himself an exile in his own land. so we have come here today to dramatize an appalling condition.
in a sense we have come to our nation's capital to cash a check. when the architects of our republic wrote the magnificent words of the constitution and the declaration of independence, they were signing a promissory note to which every american was to fall heir. this note was a promise that all men would be guaranteed the inalienable rights of life, liberty, and the pursuit of happiness.
it is obvious today that america has defaulted on this promissory note insofar as her citizens of color are concerned. instead of honoring this sacred obligation, america has given the negro people a bad check which has come back marked "insufficient funds." but we refuse to believe that the bank of justice is bankrupt. we refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation.
so we have come to cash this check -- a check that will give us upon demand the riches of freedom and the security of justice.
we have also come to this hallowed spot to remind america of the fierce urgency of now. this is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. now is the time to open the doors of opportunity to all of god's children. now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood.

关于发明英语演讲稿3分钟 篇9good afternoon ,ladies and gentlemen!
i’m very honored to stand here and give you a short speech! to begin with ,i want to ask a question .does everybody dream a good dream last night? actually ,today i want to talk about dream with you. of course, what i want to talk is not a dream you have last night,but a dream—— about life.
everyone has dreams about life, different dreams at different life stage,and we need dreams to support us. dreams are like the stars we never reach in the sky,but like most mariners(水手),we can chart our course by them. with the dream,we have a direction,with a direction, we were no longer confused.with the dream, there is hope,with hope, we have the strength to fight.
i'll do every bit to cure the incurable. i hope to see a world where there is no cancer, no aids, no fatal diseases. i'm confident that through the joint efforts of you and me, man will put an end to his bodily sufferings and this dream of mine will one day be brought into reality.

我是6班,我的名字是某某,我很荣幸在这里讲话,我很高兴能和你分享我的话题,做我们自己的事。
随着社会的发展,越来越多的人迷失了自我,他们不知道自己想做什么,他们不知道自己在做什么,这是多么可怕!
对于我们,我们不能选择出生,我们不能选择我们的父母,我们不能选择我们的出生国,我们不能选择我们的死亡时间,但我们可以选择如何面对我们的生活:幸福或不快乐,积极或消极。什么是重要的,我们应该做什么,我们不应该做什么,我们可以自己决定。不管我们如何选择和决定,所有这些都是由我们做的,所以不要太在意别人怎么看你,只做自己,自己做。
让我们做一颗心吧,让我们活在阳光下,让我们的生活更有意义,做我们想做的事,做我们自己做的事,做我们自己的事。
这是所有的,谢谢你的聆听。
关于发明英语演讲稿3分钟 篇11"If you don't want to wake up and find you have no pants to wear, you'd better put themon in sleep," goes a popular joke among students. Obviously, campus thefts have becomeincreasingly annoying as they occur far more often than before. And it seems that the thievesare less choosy these days, with their targets ranging widely from bikes, cell phones, purses,pre-paid IC cards to sunglasses, bags, and even underwear. In short, anything that worth adime is likely to be stolen.
What makes students the easy targets? The reasons are not hard to find. But I believe ofall these reasons, the lack of anti-theft alertness is the most important. For lack of alertness,the students tend to leave the doors and windows wide open during sleep at noon or at nightin summer. For the same reason, they'll also leave their bikes unlocked before a store or by aroad, or forget to take away their personal stuff before they go out of the classroom to make aphone call. These acts undoubtedly have increased their exposure to the light-fingeredmonsters.
In order to minimize possible losses, the students must stay on guard in the first place, asawareness of the thefts around often makes a big difference. To be more specific, thestudents should not hide any tempting amount of cash in the dorm. Put it in the bank instead.Besides, do not leave any valuable items unattended. Take them wherever you go. Inaddition, it's advisable to develop a neighbourhood watch programme with other students inthe dorm and neighbouring dorms.
关于发明英语演讲稿3分钟 篇12good evening, honorable judges, ladies and gentlemen.
it’s my great pleasure to stand here to present my speech—change the world, change ourselves.
it’s noticable that western holidays are becoming increasingly popular day by day, while chinese traditional festivals are being somewhat neglected. not long before about 10 doctors in beijing university and qinghua unversity announced that we should reject the invasion of western holidays ,because they regard western holidays as an challenge against our traditional festivals and culture.
frankly speaking, i don’t quite agree with them.indeed, we should never neglect or even discard our traditonal festivals as china boasts a brilliant history and splendid traditions. (examples).but why can’t we absorb the meaningful western holidays and culture. there are obvious reasons why some western holidays are so popular in china. on the one hand, some of the western holidays which we chinese don’t have are reasonable and meaningful, such as father’s day and april fool’s day etc. on the other hand,the prevalence of globalization enables western culture to prevail in china. overwhelmed by such a trend,chinese unconsiciously get involved in western holidays and culture.
with the further development of the whole world, the cultural communication between different countries and nations becomes faster and more and more important. we are indeed from different nations, but we are the citizens of the same world, so the outstanding culture of different nations is the commom wealth of everyone on the earth.the only way for us to protect our traditional culture is to reject the foreign culture? the answer is definitely no. what we ought to do is to spare no effort to educate chinese to get to know and treasure our splendid traditions instead of rejecting foreign culture. only by educating can we set our confidence and belief towards our culture. only by educating can we preserve and promote the wealth that our ancesters left for us.
at last i’d like to share a famouse saying of gandhi with all of you ,that is:if you want to change the world, then you must change yourself first.”
关于发明英语演讲稿3分钟 篇13asking the devotees of civil rights, "when will you be satisfied?" we can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. we cannot be satisfied as long as the negro's basic mobility is from a smaller ghetto to a larger one. we can never be satisfied as long as a negro in mississippi cannot vote and a negro in new york believes he has nothing for which to vote. no, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousnelike a mighty stream.
出气就会心满意足的人将大失所望。在黑人得到公民权之前,美国既不会安宁,也不会平静。反抗的旋风将继续震撼我们国家的基石,直至光辉灿烂的正义之日来临。
but there is something that i must say to my people who stand on the warm threshold which leads into the palace of justice. in the proceof gaining our rightful place we must not be guilty of wrongful deeds. let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterneand hatred.
但是,对于站在通向正义之宫艰险门槛上的人们,有一些话我必须要说。在我们争取合法地位的过程中,切不要错误行事导致犯罪。我们切不要吞饮仇恨辛酸的苦酒,来解除对于自由的饮渴。
we must forever conduct our struggle on the high plane of dignity and discipline. we must not allow our creative protest to degenerate into physical violence. again and again we must rise to the majestic heights of meeting physical force with soul force.
我们应该永远得体地、纪律严明地进行斗争。我们不能容许我们富有创造性的抗-议沦为暴-力行动。我们应该不断升华到用灵魂力量对付肉体力量的崇高境界。
the marvelous new militancy which has engulfed the negro community must not lead us to distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny and their freedom is inextricably bound to our freedom.
席卷黑人社会的新的奇迹般的战斗精神,不应导致我们对所有白人的不信任——因为许多白人兄弟已经认识到:他们的命运同我们的命运紧密相连,他们的自由同我们的自由休戚相关。他们今天来到这里参加集会就是明证。
we cannot walk alone.and as we walk, we must make the pledge that we shall march ahead. we cannot turn back. there are those who are.
关于发明英语演讲稿3分钟 篇14Good evening, Ladies and Gentlemen:
I'd like to start with a group of pictures.
“Modern and advanced”This society forgets, and ignores the other two thirds of human beings. It's far from the ideal! We call ideal as a utopian, a place where reality does not exist. A few people still look forward to the ideals. We make fun of them, considering they are naive. Will we still be content to live in such a society, if misfortune drops to us? No! Of cause not!
When we feel the warmth of the sun, these people, endure great sorrows and pains. Can we imagine that? They are our brother and sisters!
Facing them, will we still complain about our own misfortune?
Facing them, will we still have the mood shouting for our own freedom? Facing them, will we still want to have more and more unnecessary stuff?
They are unable to meet their needs, even the basic needs of survival! Everyone, as a member of humanity, shouldn't feel ashamed? Our luxury deprived their lives, our indifference violated our soul, and our barbarity destroyed human civilization!
What's the ideal society? It's a society no one worries about their living, a society no one is refused from education, a society everyone can pursue his/her own happiness! The ideal society is filled with love, joy and kindness. In that society, we can touch the other's hearts, we can share our dreams and most important, we can just be the true men!
Let's break the ethnic divide, bridge the gap between rich and poor, hand in hand, to build a Great wall, protecting us from evil; to construct a steady bridge, connecting reality to the ideal society! Let's pursue for that, that's the only way to the bright future! They are watching us! Thank you!
Smoking is a greater cause of death and disability than any single disease, says the World Health Organisation.
According to their figures, it is responsible for approximately five million deaths worldwide every year.
Tobacco smoking is a known or probable cause of approximately 25 diseases, and even the WHO says that its impact on world health is not fully assessed.
Heart attack and stroke.
UK studies show that smokers in their 30s and 40s are five times more likely to have a heart attack than non'smokers.
关于发明英语演讲稿3分钟 篇15Imagine a car without a steering wheel. Tough to imagine, right? Well, actually that’s the image you see if a person has no faith. Faith helps to guide us in our lives, encourage us to persist, and give directions when we are lost.
In this peaceful era, our life paths seem to be already well-planned and determined. What we have to do is to follow. Yes, we may face different sorts of challenges, but at least they are less harsh when compared to those in the past. We do not need to worry about starving to death, or how to earn enough money to buy food for our siblings and sustain our lives.
It is like driving from a muddy road into a highway. In the muddy road, path, you would say, as it is formed only by crossing on it many times, flattening the ground to form a smoother area so we can pass. The road is so bumpy and rough, with holes here and there and rocks lying all over. When we drive along this road, we have to be very careful, having a firm grip on the steering wheel, ready for a sudden turn or a large boulder that may appear any second. However, when we drive on a highway, everything becomes different. The road is smooth, straight, and visible. Since there is no unseen obstacle, we may lower our guard, relax a bit, and loosen our grip on the steering wheel. One may even think, if we only have to drive on a smooth straight road like this highway, why would we need a steering wheel?
Nevertheless, one cannot foresee the future. Accidents do happen. For example, a car may suddenly appear in front of you. At such times, if you did not have the steering wheel, how could you make a sudden turn? Just as no one could foresee the Sichuan Earthquake nor the Japan Tsunami. If the one being trapped under the debris did not have faith, he/she would not have survived until being rescued. If we did not have faith, we could not recover from our sadness and rebuild our home.
Faith is unique, just as happiness is. We feel happy for different reasons, we believe for different things. How can we know what we believe in? Recall the last time you are discouraged, and you felt you had lost all hopes in your life. What pulled you back into the world? What pushed you to stand up and continue to strive again? That is your faith, your belief. Faith is what makes you feel you can when others say you can’t.
Faith is important…, faith is vital…, faith is necessary for us to live our lives. If we do not have faith, we are like a car without a steeling wheel. We can only afford to move along a straight and smooth path, and cannot meet any challenge in our lives. One must understand that no matter how smooth the road is, it is impossible for a car to go without a steering wheel. Or, put it in another way, have you ever seen a car without a steering wheel on the road? So, act now, my friends, find out what you believe in, find out your anchor in your life, hold on to your steeling wheel of your car, drive on, and reach your destination. Thank you very much.

关于发明英语演讲稿3分钟 篇17change the ingredients of your life
this is a glass of water, tasteless, right? however if you add sugar, it will taste sweet, but if you add vinegar, it will become bitter. the same is true with our life____ the flavor is created by our choices.
if kindness is added to a strange you will have a friend; but if hostility is added, you will have an enemy. if love is added to a pile of red bricks you will have a home, but if hatred is add to those bricks , you will have an concentration camp.
so my dear friends, never complain that life is boring and the world is disappointing. if don’t like the taste of your life, change the ingredients. three year ago, i weighed more than 100 hundred kilograms which caused significant embarrassment and frustration in my life. like always failing my p.e examinations, like always being laughed at by girls, like being terrified to speak in public. it was my grandmother’s encouragement that revived from my passive attitude to become confident in myself. she said “ my dear, if you can’t change you figure, why not treat it as your own style. so i began to cautiously employ the new way of thinking. by choosing to change my outlook on life, i developed the confidence to make a difference and finally i found a totally new world. so my dear friend, if faith, hope, love, endurance are added to your life, you will find the confidence to conquer your limitation and embrace new challenges. and hopefully with my speech included, you will have a fantastic speech contest.
