Today I am very glad to be here to share with you my ideas of success. What is success? It is what everyone is longing for.Sometimes success would be rather simple. Winning a game is success; getting a high grade in the exam is success; making a new friend is success; even now I am standing here giving my speech is somehow also success.
However, as a person's whole life is concerned, success becomes very complicated. Is fortune success? Is fame success? Is high social status success? No, I don’t think so. I believe success is the realization of people's hopes and ideals.Nowadays, in the modern society there are many people who are regarded as the successful. And the most obvious characteristics of them are money, high position and luxurious life. So most people believe that s success and all that they do is for this purpose. But the problem is wether it is real success. We all know there are always more money, higher position and better condition in front of us. If we keep chasing them, where is the end? What will satisfy us at last? Therefore, we can see, to get the real Success we must need something inside, which is the realization of people's hopes and ideals.
Different people have different ideas about success; cause people's hopes and ideas vary from one another. But I am sure every success is dear to everybody, cause it is not easy to come by, cause in the process of our striving for success, we got both our body and soul tempted, meanwhile we are enlightened by the most valuable qualities of human beings: love, patient, courage and sense of responsibility. These are the best treasures. So now I am very proud that I have this opportunity to stand here speaking to all of you. It is my success, cause I raise up to challenge my hope.
What is success? Everyone has his own interpretation as I do. But I am sure every success leads to an ever-brighter future. So ladies and gentlemen, believe in our hopes, believe in ourselves, we, every one of us, can make a successful life!
Wish you all good success!
youth is not a time of life, it is a state of mind it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. this often existsin a man of 60 more than a boy of 20 . nobody grows old merely by a number of years . we grow old by deserting our ideals.
years wrinkle the skin , but to give up enthusiasm wrinkles the soul .worry , fear , self –distrust bows the heart and turns the spirit back to dust .
whether 60 of 16 , there is in every human being „s heart the lure of wonders, the unfailing childlike appetite of what‟s next and the joy of the game of living . in the center of your heart and my heart there‟s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young .
when the aerials are down , and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80.
thank you!
One day in 1819, 3,000 miles off the coast of Chile, in one of the most remote regions of the Pacific Ocean, 20 American sailors watched their ship flood with seawater.
They'd been struck by a sperm whale, which had ripped a catastrophic hole in the ship's hull. As their ship began to sink beneath the swells, the men huddled together in three small whaleboats.
These men were 10,000 miles from home, more than 1,000 miles from the nearest scrap of land. In their small boats, they carried only rudimentary navigational equipment and limited supplies of food and water.
These were the men of the whaleship Essex, whose story would later inspire parts of “Moby Dick.”
Even in today's world, their situation would be really dire, but think about how much worse it would have been then.
No one on land had any idea that anything had gone wrong. No search party was coming to look for these men. So most of us have never experienced a situation as frightening as the one in which these sailors found themselves, but we all know what it's like to be afraid.
We know how fear feels, but I'm not sure we spend enough time thinking about what our fears mean.
As we grow up, we're often encouraged to think of fear as a weakness, just another childish thing to discard like baby teeth or roller skates.
And I think it's no accident that we think this way. Neuroscientists have actually shown that human beings are hard'wired to be optimists.
So maybe that's why we think of fear, sometimes, as a danger in and of itself. “Don't worry,” we like to say to one another. “Don't panic.” In English, fear is something we conquer. It's something we fight.
everyone to contribute for the expo, we are no exception, as a living piece of fertile land in pudong's teachers, we are proud and pride. in the vision of a better tomorrowwe have to do for the world expo will own a wonderful ability, we have through our hands, warm heart and sincerity to practical action to achieve the commitment of shanghai to the world. we should educate the many students: do not throw garbage anywhere, no spitting, no jaywalking ... ..., hello, thank you frequently mention, let the material on this city with the new york comparable to the spiritual civilization. educate our students to exciting , willing to shanghai's future by copies of power, if only planted a small tree, participants in the shanghai world expo foreign guests feel: this is a forest city, pollution-free city, ancient and civilized city. better city, better life! until the time of the expo, then, we want to become a glorious volunteers, to changing our foreign friends in shanghai and china's long history, about our education for the world expo will contribute their efforts.
we expect the majority of teachers will be great enthusiasm for the world expo into practical action to meet the world expo, the expo will be a total growth, and the city of development, the development of shanghai devote their efforts to advance hand in hand with shanghai.
It is true that most of us value honesty highly. However, nowadays we often confront confidence crisis such as cheating, overcharging, fake commodities and so on. I think that we should be honest because being honest is not only beneficial to ourselves but also to others and the whole society. The reasons can be listed as follows.Firstly, only honest people can be truly respected by the others and can make more friends over a long period of time.
Secondly, honesty, which is the traditional virtue of the Chinese people, can make our life easier and more harmonious. Thirdly, honesty can make our society more stable. A case in point is that Singapore, a society featuring trustworthiness and integrity, has a comparatively low criminal rate.
Responsbility can be understood in many ways. for the parents , they have had the responsibility for caring for and fostering their children since the birth of their baby.for teachers,both in kindergartens and colleges,they also should be responsible for the study and life of their students,that is to say,teahers are the second parents of children somewhile.
for us,as a friend of others,it is our responsibility to help our friends when they are in trouble or faced with difficulties. each one has the different responsibily based on their roles but we must take it for granted that we are responsible for the society.
the footsteps of the world expo is getting closer and closer to us, civilized and harmonious call is still ringing in my ears. shanghai, china obtained the right to host the world expo , expo shanghai china will be a world event, the development of shanghai's new round of golden opportunity, as it is an important embodiment of our national spirit.
world expo is a great influence and a long history of international activities, is the largest gathering of human beings. people from around the world gathered in one place display their products and skills, boast of their hometown and motherland. expo set the culmination of human civilization, which has a unique appeal, make you feel surging.
world expo is a platform, we are the masters. she put up a platform for us to let the world know us; she built a bridge for us, so we better communicate with the world. this platform may let us display self wantonly. we are the masters here, we have to landlord, let guest experience enthusiasm and happiness.
I also realize that only those who bring happiness for others can be truly happy. So I often take part in activities concerning public welfare. I once went to a barren mountain village with my classmates. We taught the kids there who could not afford school. While showing them how broad and how civilized the outer world is, I was deeply touched by their eagerness to learn, their honesty and their purity. I couldn't control my tears on the day when we left. The precious experience with the poor kids made me aware of the responsibility on the shoulders of us, future teachers.
Besides study and social practice, there are entertainments as well. I do body building every day, hoping to keep healthy and energetic. We also write a play and put it on in our spare time.
Campus life is the most splendid time. But different people have different choices. The majority of students cherish their beautiful season and cherish the hope that one day they'll become outstanding. But there are indeed some students still under ignorance. They gather together for eating, drinking or playing cards. They're busy in searching for a girlfriend or a boyfriend. They forget completely about their mission as college students and the hope of their motherland.
Finally, I do hope everybody can try their best to become a worthy citizen of the country. I do hope everybody can become the backbone of our nation and make great contributions to society!
Good morning, my dear teachers and friends! My name is Li Binge, from class four O five. Today, I am very happy to be here. My topic is “Our School”.
My dear friends, welcome to our school! My school is very beautiful! It has a big playground. We can play and do some sports there. Near the playground, there is a garden. Many trees and flowers are there. So the air is very clean and we can hear birds singing in the trees. It is so wonderful. Our teaching buildings are around the garden and look like our teachers’ arms to welcome us. We can draw pictures in the art room on the first floor and read story-books in the library on the second floor. My classroom is on the third floor. It is clean and bright. We like to study in it. The computer room is on the fifth floor. We can sing and dance in the music room on the sixth floor. What a lot of fun! We can have lunch in the canteen near Defang Teaching Building.
In our school, our teachers work hard and help us with our lessons. We study hard and listen to teachers carefully. After class, our teachers play with us and we feel very happy.
Our school is so nice and our teachers are so kind. We all love them. Dear friends, do you like them?That's all. Thanks!
Ladies and Gentlemen, Good morning! I’m very glad to stand here and give you a short speech.
Man’s life is a process of growing up, actually I’m standing here is a growth. If a person’s life must constituted by various choices, then I grow up along with these choices. Once I hope I can study in a college in future, however that’s passed, as you know I come here, now I wonder what the future holds for me.
When I come to this school, I told to myself: this my near future, all starts here. Following I will learn to become a man, a integrated man, who has a fine body, can take on important task, has independent thought, an open mind, intensive thought, has the ability to judge right and wrong, has a perfect job.
Once my teacher said :” you are not sewing, you are stylist; never forget which you should lay out to people is your thought, not craft.” I will put my personality with my interest and ability into my study, during these process I will combine learning with doing. If I can achieve this “future”, I think that I really grow up. And I deeply believe kindred, good-fellowship and love will perfection and happy in the future.
How to say future? Maybe it’s a nice wish. Lets make up our minds, stick to it and surely well enjoy our life.
The environment of the world has been damaged by the human beings for so many years without much notice.In recent years,however,more and more nations have begun to preserve the environment as they have realized the importance of it.
The nature has given us so much,but look at what we have done in return for its generosity.Thousands upon thousands of trees have been cut down,including some precious species. Numerous rivers and lakes have been drained only to set up modern buildings. Priceless wildlife has turned into delicious dishes on the table.The air is being befouled by the smoke from the chimneys of the plants...
All this irritates the nature ,which results in the shortage of valuable resources,air pollution,countless acres of lands becoming deserts,etc.Fortunately,many countries have got to know the seriousness of the problem and take active measures to preserve the environment.We sincerely hope that all the peo;le in the world willtake part in the campaign and join hands to protect the nature.
Can money buy happiness? Different people have different opinions. Some think yes, while others hold the opposite.
It is true that with enough money one can buy all the things one wants, and live a life of comfort and security. However, it is equally true that lack of money causes great distress. It is a common view that "money is the root of all evil." The pursuit of money drives many people to cheat and steal. In some places there is nothing that cannot be bought with money, resulting in corrupt societies where everybody is miserable.
So, money does not necessarily mean happiness. It all depends on how it is used. If we make honest and sensible use of money, it can be a stepping-stone to happiness l Although money cannot buy happiness, it can make happiness possible if it is employed sensibly.
译文：
金钱能买到幸福吗?不同的人有不同的看法。有些人认为是的，而另一些人则持相反的想法。
这是真的，有足够的钱，人们可以买到一个人想要的一切东西，并过上舒适和安全的生活。然而，同样的事实是，缺乏资金会造成巨大的痛苦。“钱是一切罪恶的根源”是一种普遍的观点，对金钱的追求驱使许多人去欺骗和偷窃。在一些地方，没有什么是不能用金钱买来的，在腐化的社会，每个人都是悲惨的。
所以，金钱并不一定意味着幸福。这都取决于它是如何使用。如果我们诚信明智地使用金钱，它将是幸福的基石虽然金钱买不到幸福，但它可以使幸福成为可能。
There was a man who had seven sons, but he had no daughter, greatly though he longed for one. At last his wife told him that they could again expect a child and, sure enough, when it was born it was a baby girl. There was great rejoicing, but the child was weak and puny, so weak that it had to be christened at once. The father told one of the boys to go quickly to the spring and fetch christening water; the other six ran along with him, and because each of them wanted to be the first to dip the jug into the well, it fell in and sank. So there they stood and didn't know what to do, and none of them dared go home. When they didn't come back their father got impatient and said:" I'll wager they've been playing some game again and forgotten all about it, the godless brats." He was afraid the little girl would have to die unbaptized, and in his rage he cried out:" I wish those boys would all turn into ravens." He'd scarcely spoken the words when he heard a whirring of wings in the air overhead, looked up and saw seven coal-black ravens flying away.
As the whole world has its boundaries， limits and freedom coexist in our life. I don’t expect complete freedom， which is impossible. I simply have a dream that supports my life.
I dream that one day， I could escape from the deep sea of thick schoolbooks and lead my own life. With my favorite fictions， I lie freely on the green grass， smelling the spring， listening to the wind singing， breathing the fresh and cool air and dissolve my soul in nature at last. Simple and short enjoyment can bring me great satisfaction.
I dream that one day the adults could throw their prejudice of comic and cartoon away. They could keep a lovely heart that can share sorrow and happiness with us while watching cartoon or doing personal things. That’s the real communication of heart to heart.
I have the belief that my dreams should come true. I am looking forward to some day coming when I am like a proud eagle， which flies to the blue and vast sky.
译文：
由于整个世界都有它的界限，限制和自由在我们的生活中共存。我不期望完全的自由，这是不可能的。我只是有一个梦想，支持我的生活。
我梦想有一天，我可以摆脱厚厚的教科书，并导致深海我自己的生活。用我最喜欢的小说，我躺在草地上自由地躺在草地上，闻着春天的气息，听着风的歌声，呼吸着清新凉爽的空气，最后把我的灵魂溶解在大自然中。简单的和短期的享受可以给我带来极大的满足感。
我梦想有一天，成年人可以把他们的偏见的漫画和卡通了。他们可以保持一个可爱的心，可以与我们分享悲伤和快乐，而看卡通或做个人的事情。这是心与心的真正交流。
我相信我的梦想会成真。我期待着有一天的到来，当我像一只骄傲的鹰，飞向蓝色和广阔的天空。
Like a child endlessly asking, we humans, throughout history, have been continually demanding what we desire from nature. We enjoy the comfort and beauty of our furniture, yet we never bother to think about the serious soil erosion caused by deforestation. We take it for granted that we must warm ourselves in winter times, yet we seldom realize the burning away of precious natural resources. We appreciate all the prosperity from the development of modern industry, yet few would give the slightest consideration to the global air and water pollution caused by industrial wastes. Our ruthless exploitation has permanently impaired our mother earth. As we tragically learned from last summer's floods. we cannot continue our carelessness.
Finally, standing here at the threshold of the 21st century, we cannot help thinking of our posterity. Nature is not only the mother of the present generation, but also the mother of the generations to come. How severely our descendents will criticize us if we leave them a barren and lifeless mother? How much more they will appreciate us if we give them a world of harmony to inherit? Let us start respecting and caring for nature from now on. Let us start the campaign of creating a mutually beneficial relationship between people and nature right from this moment. With this new start, I firmly believe, that our children, and our children's children will live in a brand new age of green trees, clean air, crystal water, blue sky and an even more promising world!
I have a dream
Every one has his own dream.When I was a little kid ,my dream was even to have a candy shop of my own .But now ,when I am 16 years old ,standing here ,my dreams have already changed a lot.
I have got quite different experience from other girls.While they were playing toys at home,while they were dreaming to be the princesses in the story .I was running in the hard rain,jumping in the heavy snow,pitching in the strong wind.Nothing could stop me ,because of a wonderful call from my heart -- to be an athlete.Yeah ,of course ,I'm an athlete,I'm so proud of that all the time .
When I was 10 years old ,I became a shot-put athlete.The training was really hard ,I couldn't bear the heavy shot in my hands .But I always believe that "god only help those who help themselves".During those hard days,I find I was growing more quickly than others of the same age.To be an athlete is my most correct choice.But,I quit my team after entering high school because of a silly excuse.I really didn't want to stop my sports career anyway.
Today I say to you my friends that even though I must face the difficulties of yesterday ,today and tomorrow .I still have a dream .It is a dream deeply rooted in my soul.
I have a dream that one day ,I can run,jump and pitch just like I used to be.
I have a dream that one day , I can go back to my dream sports and join the national team.
I have a dream that one day ,I can stand on the highest place at the olympic games.With all the cameras pointing at me.I will tell everyone that I'm so proud to be a Chinese athlete!
This is my hope .This is the faith that I continue my steps with!!!
With this faith ,I will live though the strong wind and heavy rain ,never give up !
So let victory ring from my heart,from all of you.When we allow victory to ring .I must be the one!
In my imagination,I'm a bird ,a magical bird.I carry my dreams all with me by my big wings. I fly though the mountains ,though the forests ,over the sea,to the sun ,the warmest place in the aerospace!
Every night ,I have a dream ,I see a girl ---smiling~
Ladies and Gentlemen, Good afternoon!
I’m very glad to stand here and give you a short speech. Today my topic is “youth”. I hope you will like it, and found the importance in your youth so that more cherish it.
First I want to ask you some questions:
1、Do you know what is youth? 2、How do you master your youth?
Youth
Youth is not a time of life, it is a state of mind; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .
Youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20 . Nobody grows old merely by a number of years. We grow old by deserting our ideals.
Years wrinkle the skin, but to give up enthusiasm wrinkles the soul. Worry, fear, self –distrust bows the heart and turns the spirit back to dust.
Whether 60 of 16, there is in every human being ‘s heart the lure of wonders, the unfailing childlike appetite of what’s next and the joy of the game of living . In the center of your heart and my heart there’s a wireless station: so long as it receives messages of beauty, hope ,cheer, courage and power from men and from the infinite, so long as you are young .
When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80.
Thank you!
青春
青春不是指岁月，而是指心态。粉嫩的脸，红润的唇，矫健的膝并不是青春。青春表现在意志的坚强与懦弱。想象的丰富与苍白、情感的充沛与贫乏等方面。青春是生命深处清泉的喷涌。
青春是追求。只有当勇气盖过怯弱、进取压倒苟安之时，青春才存在。果如此，则60见之长者比20岁之少年更具青春活力。仅仅岁月的流逝并不能使他们衰老。而一旦抛弃理想和信念，则垂垂老也。
岁月只能使皮肤起皱。而一旦丧失生活的激情，则连灵魂枯老，使人生枯如死水，毫无活力。 60岁长者也好，16岁少年也罢，每个人的内心深处都渴望奇迹，都如孩子一般眨着期待的双眼，期待着下一次，期待着生活的情趣，你我灵魂深处都有一座无线电中转站------只有你我年轻，则总能听到希望的呼唤，总能发出喜悦的欢呼，总能传达勇气的讯号，总能表现出青春的活力„„„
一旦青春的天线倒下，你的灵魂即为玩世不恭之雪、悲观厌世之冰覆盖;即使你年方
20.其实你已垂垂老也。而只要你青春的天线高高耸起，就可以随时接收到乐观的电波-----即使你年过八旬，行将就木，而你却仍然拥有青春，你仍然年轻。
谢谢!
Good morning, my dear teachers and friends! My name is Li Binge, from class four O five. Today, I am very happy to be here. My topic is “Our School”.
My dear friends, welcome to our school! My school is very beautiful! It has a big playground. We can play and do some sports there. Near the playground, there is a garden. Many trees and flowers are there. So the air is very clean and we can hear birds singing in the trees. It is so wonderful. Our teaching buildings are around the garden and look like our teachers’ arms to welcome us. We can draw pictures in the art room on the first floor and read story-books in the library on the second floor. My classroom is on the third floor. It is clean and bright. We like to study in it. The computer room is on the fifth floor. We can sing and dance in the music room on the sixth floor. What a lot of fun! We can have lunch in the canteen near Defang Teaching Building.
In our school, our teachers work hard and help us with our lessons. We study hard and listen to teachers carefully. After class, our teachers play with us and we feel very happy.
Our school is so nice and our teachers are so kind. We all love them. Dear friends, do you like them?That's all. Thanks!
dear teacher, dear students:
hello everybody!
my topic today is "making the self-confidence."
thomas edison once said: "confidence is the first secret of success." yes, in life, we can not do without self-confidence everywhere. a person without faith, is bound to be abandoned by the society of a person, a person has been abandoned by successful, one was abandoned by the people themselves! therefore, we can say without hesitation: self-confidence is a person's soul!
self-confidence does not equal arrogance. it is a determination, has the power over life and death. never blindly self-confidence, it is hard honing the ability of the condensed. ability is like the crown, it is only mounted on a self-confident fengyun sparkling diamonds, will become eye-catching and gorgeous. similarly, there is no ability to foil, and let confidence no matter how brilliant, but also like the loss of green flowers, value greatly reduced.
i believe we all heard of "with confidence" the idiom story! good at the northern song painter painting paper with bamboo, when pen to paper without thinking each time they claimed a life-like bamboo map. how did he do it? it turned out that his daily observation of the bamboo hut, seasons, his unshakeable. over time, the length of bamboo thickness, leaf shape color, he is familiar with the heart, naturally, put the bamboo painted superb.
this is the power of self-confidence!
feeling of youth
no young man believes he shall ever die. it was a saying of my brother's, and a fine one. there is a feeling of eternity in youth, which makes us amend for everything. to be young is to be as one of the immortal gods. one half of time indeed is flown-the other half remains in store for us with all its countletreasures; for there is no line drawn, and we see no limit to our hopes and wishes. we make the coming age our own-
the vast, the unbounded prospect lies before us.
death. old age. are words without a meaning. that paby us like the idea air which we regard not. others may have undergone, or may still be liable to them-we "bear a charmed life“, which laughs to scorn all such sickly fancies. as in setting out on delightful journey, we strain our eager gaze forward-
bidding the lovely scenes at distance hail!
It's something we overcome. But what if we looked at fear in a fresh way? What if we thought of fear as an amazing act of the imagination, something that can be as profound and insightful as storytelling itself?
It's easiest to see this link between fear and the imagination in young children, whose fears are often extraordinarily vivid.
When I was a child, I lived in California, which is, you know, mostly a very nice place to live, but for me as a child, California could also be a little scary.
I remember how frightening it was to see the chandelier that hung above our dining table swing back and forth during every minor earthquake, and I sometimes couldn't sleep at night, terrified that the Big One might strike while we were sleeping.
And what we say about kids who have fears like that is that they have a vivid imagination. But at a certain point, most of us learn to leave these kinds of visions behind and grow up.
We learn that there are no monsters hiding under the bed, and not every earthquake brings buildings down. But maybe it's no coincidence that some of our most creative minds fail to leave these kinds of fears behind as adults.
Ladies and Gentlemen, Good morning! I’m very glad to stand here and give you a short speech.
Man’s life is a process of growing up, actually I’m standing here is a growth. If a person’s life must constituted by various choices, then I grow up along with these choices.

Soy food good for women
Women who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research.
The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise.
The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects.
A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week.
Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.
据美国研究人员报告，儿童时期经常吃豆类食品的女性患乳腺癌的风险较小。另一组研究人员则向美国癌症研究协会提出，一周吃几次鱼的男性患结肠癌的几率较小。
这两项研究进一步证明了饮食对于防癌的作用。癌症防治专家认为，在所有种类的癌症中，多达三分之二都是由吸烟、节食及缺乏锻炼等不健康的生活方式造成的。
美国全国癌症研究所和夏威夷大学的研究人员发现，在5岁至11岁时经常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%。至于豆类食品为什么可以防癌还不清楚，不过大豆中所含的名叫异黄酮的化合物具有雌性激素的作用。
另一项研究表明，一周吃鱼至少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。很多鱼类中所富含的Omega-3脂肪酸能够抑制环氧化酶2的活性。环氧化酶2会引起发炎，这可能会刺激肿瘤的生长。
