　　Hello, ladies and gentlemen. It’s great to be here. First of all, thanks for your coming. Tonight, what I am gonna talk about is innovation. Who can tell me what is innovation? We all know that, since 1978, China has been through the greatest changes brought by the reform and openingxup. So what we can see from the reform and openingxup? The power of innovation. That’s why I am here. I am here to show you my Chinese dream.

　　I want to talk about the future and how we're going to win it. If we want to make innovation. But firstly, we should make sure that China is a place where we can make it if we try, where we can go as far as hard work and big dreams will take us. We understand that it’s not going to be a cakewalk, this competition for the future, which means all of us are going to have to do our best. We are going to have to win the future by being smarter and working harder and working together. Innovation is the spirit of our country, the motive force for our country’s prosperity.

　　Sparking the imagination and creativity of our people, unleashing new discoveries xx that's what China will do better than any other country on Earth. From the moment we have a new idea, we can explore it; we can develop it with a research grant; we can protect it with a patent; we can market it with a loan to start a new business. We’ve got a chain that takes a great idea all the way through. We must be confirmed that, today, the challenges we face are real. They are serious they are many. They will not be met easily or in a short span of time. But we will somehow find a way to overcome the difficulties. My major is . My is to discover or create new drugs for many diseases like cancer. You know that laboratory is the place where miracles happen. Believe it or not.

　　What I do can save millions of people’s lives. For a long time, what challenges me is how to commercialize research. You come up with a great idea, but moving that new discovery from theory to practice or from the lab to the marketplace, that's really a big . That’s what we should focus on. We need to act with a sense of urgencyxto study and work and create as if the fate of the country depends on usxbecause it does. It depends on us. Thank you!

Dears，

　　Good morning all!

　　On New Years Eve， our class had a party. The atmosphere was good. It was out of the ordinary from the very begining. The boy student from one bedroom gave an unusual performance. We saw a boy named Li Xinmin turn off all the lights in a sudden snap. Then with three resounding crow of a cock echoing in the hall， the hall was again brightly lit in a snap.

　　Then， the representative of the bedroom Zhu Guozhang asked us to guess a line of a poem related to the above situation. He added that Li Xinmin alone was born in the year of the dog and the other three were all born in the year of the chicken. They left us all in confusion. And it was our monitor who was quickwitted. He shouted our， “The day breaks as the cock crows three times at dawn. ” The hall After that， they had another item.

　　This time Li Xinmin was placed in the middle of the circle. While he was standing there， the other three stood around him， each bowing down to him at an angle of 120 degrees. It was an idiom. This time I got it right:“The dog stands out among a group of chickens. ”

　　Then we all sang and played games until it was eleven o&39;clock at night. The old man on night watch came to turn off the lights. We had to tear ourselves away from the party.

　　From this activity， I discovered that many of our classmates are really talented singers.

　　Good afternoon Ladies and Gentlemen,

　　Want to know how to feel bad about yourself? These tips are 100% effectiveand are guaranteed to make you feel really, really bad about yourself!

　　No.1 Compare yourself to everyone and everything around. Pick out thingsthey have that you don't;think how “lucky” they are and how “unlucky” youare.

　　No.2 Tell yourself over and over again things like “I am horrible”, “I amugly”, “I am disgusting”, or “I am useless.”

　　Sometimes, without even really knowing it, we can actively choose to bemiserable! In reality, it is more likely that you would like to invite feelingsof low self-esteem into your life. Low self-esteem has been attributed as beinga major obstacle to success. A recent survey conducted by the China PopulationCommunication Centershowed that nearly half of the interviewed studentssaid thatthey lacked a sense of security in social interactionsand suffered from lowself-esteem. Young people are the back bone to the nation. Their actions andattitudes are like a barometer of the health of a society. If our youth arecourageous and have faith in themselves, they can contribute to the developmentof our nation and our society will be in good health. On the contrary, if theysuffer from low self-esteem, our society will get sick.

　　I would like to share with you a true story about Nicholas James was born with Tetra-amelia, a rare disorder characterized by the absence ofall four limbs. He struggled as a child, eventually came to terms with hisdisability and started his own non-profit organization Life Without Limbs – atage seventeen. He is widely known as a motivational speaker, giving talksworldwide on life with a disability, hope, and finding meaning in life.

　　He was bullied at school, Vujicic grew depressed and by the age of 8,contemplated suicide. At age 10, he tried to drown himself in 4 inches of water,but did not go through with it out of love for his parents. After praying togrow arms and legs, Vujicic eventually realized that his accomplishments couldinspire others – and became grateful for his life. A key turning point came whenhis mother showed him a newspaper article about a man dealing with a severedisability. Vujicic realized he wasn't unique in his struggles and began toembrace and transcend his disability.

　　This man, the soldier of life, came to my hometown 2 months ago. I got tolisten to him, and talk to him, face to face. I could never forget the look inhis face when he said “when I was young, I always feel cold, and dark. My firstdream was to grow arms and legs, but there is no future for me at all. ” Andnow, 28 years has passed since he was born, 28 years without arms and ’s first dream didn't come true, but he didn't lose his faith of himself,and the faith of this life.

　　Nick is living a life without limbs, and also a life without are to him, young people, there is no excuses to lose our faith in ourselvesand this world. I understand that life couldn't be anything we want it to be,and life couldn't bring us everything we long for, sometimes, life even takesaway our cherished ones. However, we are young; we are the hope of the wholeworld. Faith is right there within our reach.

　　Never lose faith, let us make to our life, to our future a dearpromise.

　　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!

　　Good afternoon, honorable judges, dear teachers & friends.

　　I'm Lai Senhan from the University of International Business & Economics. Do you know what date is it today? Today is the Olympic Date. I'm so glad to stand here today to share my idea about Beijing Olympic Games together with you all. The title of my speech is: what can we do for Beijing Olympic Games?

　　First of all, let me tell you a story that happened 2 years ago. At the end of August, 20xx, when I decided to come to Beijing for study, my friends hel* * **rewell Party for me. They said: after your graduation, you should look for a job in Beijing, and then in 20xx, we shall go to visit you during the Olympic Games. I laughed and answered: OK, no problem!

　　Time flied and 2 years passed. Now I am a graduate. My teachers and classmates always ask me: what's your plan after your graduation? Go back home, stay in Beijing, or go to some other places? And I always answer: I will stay in Beijing. I make this decision not because of my promise to my friends 2 years ago, but because: I've fallen in love with Beijing! I'm eager to welcome the coming Olympic Games together with my fellow countrymen, and I wish I could do something for the Olympics & for the city.

　　As we know, Beijing will host the 29th Summer Olympic Games in 20xx. As a Chinese, I think many people are thinking: what we can do for Beijing Olympic Games. Most of us are not athletes, we cannot take part in competitions directly; we are not officials either, we don't need to do the preparatory work. We are only ordinary people, what we can do!

　　There are still so many things we can do! For example, for me, I am a graduate majoring Business English. As far as I am concerned, I will keep on learning English hard, and apply for being a volunteer. I will use English to serve the Games together with other volunteers. And also, as a businessman at that time, I will avail myself of the great commercial opportunities that the Olympics brings to us, make more efforts to offer my contribution to the growth of our national economy.

　　And for all of us, with the goal to host a "Green Olympics", we shall plant more trees, grass & flowers. Don't waste water. In order to alleviate the problems of air pollution & traffic congestions, we shall take buses & subways more. With the goal to host a "People's Olympics", and in order to make our Olympics more attractive and to make our Beijing more beautiful, we shall help everyone we meet who needs help, we shall abide by traffic rules, don't smoke in public and no spitting. The most important way for our Chinese to support our Beijing Olympic Games, in my opinion, is to work hard on our duties.

　　Thank you everyone！

　　Thursday morning at school, I got four agents young movie tickets for all vouchers, I see, ah! 3 d movies? I can't seen 3 d movies. What's the difference between "what stereoscopic film and common film? Do I have to go and see." I said to himself.

　　Came to the classroom, I and my good friend Luo Kaiyun agreed during the National Day get to the cinema to see 3 d movie.

　　Easy to look forward to in the National Day, half past nine, I carried on film label and money, like a bottle of an arrow into the cinema. Arrived at the cinema, Luo Kaiyun have been waiting at the door, we hurry to buy a stereo glasses, as people into theaters, find a seat to sit. Three-dimensional film began. I'll take off glasses and a look at the screen, with ordinary film is no different, only the edge of the red, yellow, hazy outline. To wear glasses, yi! Those who like jumped out of the screen, walked over to me. Thought: this is stereoscopic film. Next, the butterfly flew in front of my eyes, seemed to stretch out my hand can get; Figure dangling in front of me; Killing passing speed seems to me; The sword stab to me; Monster as if to swallow me up, frighten I left hide right shine, heart pounding, stimulation and clinking. All of a sudden, I saw m hill iron claw straight towards my stamp, quickly close to me, "ah, arrest me?" I was scared, and instinctively recoiled hide in the body under the chair, heart like to jump out of the throat. Gee, I don't see any action, I take off glasses a look, turned out to be a movie, I really put it. An hour and a half, I have spent in stimulation, scary.

　　Things in the past, but I will never forget.

　　but there were problems. one problem is there are some sounds in arabic that just don't make it through a european voice box without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.

　　here's one of the culprits. this is the letter sheen, and it makes the sound we think of as sh -- “sh.“ it's also the very first letter of the word shalan, which means “something“ just like the the english word “something“ -- some undefined, unknown thing.

　　now in arabic, we can make this definite by adding the definite article “al.“ so this is al-shalan -- the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.

　　the problem for the medieval spanish scholars who were tasked with translating this material is that the letter sheen and the word shalan can't be rendered into spanish because spanish doesn't have that sh, that “sh“ sound. so by convention, they created a rule in which they borrowed the ck sound, “ck“ sound, from the classical greek in the form of the letter kai.

　　later when this material was translated into a common european language, which is to say latin, they simply replaced the greek kai with the latin x. and once that happened, once this material was in latin, it formed the basis for mathematics textbooks for almost 600 years.

　　now, i tell you this story about summer camp. i could have told you 50 others just like it -- all the times that i got the message that somehow my quiet and introverted style of being was not necessarily the right way to go, that i should be trying to pass as more of an extrovert. and i always sensed deep down that this was wrong and that introverts were pretty excellent just as they were. but for years i denied this intuition, and so i became a wall street lawyer, of all things, instead of the writer that i had always longed to be -- partly because i needed to prove to myself that i could be bold and assertive too. and i was always going off to crowded bars when i really would have preferred to just have a nice dinner with friends. and i made these self-negating choices so reflexively, that i wasn't even aware that i was making them.

　　now this is what many introverts do, and it's our loss for sure, but it is also our colleagues' loss and our communities' loss. and at the risk of sounding grandiose, it is the world's loss. because when it comes to creativity and to leadership, we need introverts doing what they do best. a third to a half of the population are introverts -- a third to a half. so that's one out of every two or three people you know. so even if you're an extrovert yourself, i'm talking about your coworkers and your spouses and your children and the person sitting next to you right now -- all of them subject to this bias that is pretty deep and real in our society. we all internalize it from a very early age without even having a language for what we're doing.

　　now to see the bias clearly you need to understand what introversion is. it's different from being shy. shyness is about fear of social judgment. introversion is more about, how do you respond to stimulation, including social stimulation. so extroverts really crave large amounts of stimulation, whereas introverts feel at their most alive and their most switched-on and their most capable when they're in quieter, more low-key environments. not all the time -- these things aren't absolute -- but a lot of the time. so the key then to maximizing our talents is for us all to put ourselves in the zone of stimulation that is right for us.

　　My definition of success

　　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 amstanding 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 peoplewho are regarded as the successful. And the most obvious characteristics of hem 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’ 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!

　　As the saying goes: "a man without ambition." A person without lofty ideal, it is impossible to make a difference.

　　From ancient times pangu separated heaven and earth to today's knowledge explosion, information revolution, and how many years, how many generations, how many healthyenterprise has a lofty ideal. Ideality is the power of we forge ahead, bold innovation, the ideal is the light of life, the ideal is the source of strength to overcome all difficulties...

　　A very early age I had the first ideal is to be a policewoman. The ideal of childhood now think of is ridiculous and childish, but it is the self is like their beautiful uniforms and the brave when arresting suspects.

　　Since fourth grade until now, I have a second ideal is to be a host, stand in my ideal stage to Dong Qing, like his famous, so I started a small stage, first in class nine, almost class meetings can see me, standing on the platform host class meeting. I would often watch on the name of the host or the host renda, learn their host program statements, expression and action. Through unremitting efforts, I learned a lot, let me show hosted by better. I really like the host program, can let the audience happy, also can let oneself happy. Now I'm in step by step to realize my ideal.

　　Ideal is an abyss, from the moment of jump, will force you to fight. Or, mirs, whirlwind; Or, stone sink deep bottom, no noise... And I will choose the former, I will work hard, to own ideal step by step forward! Zhou ji daqo

　　My future is not just a dream, the future is in my hands. I want to, I should take action, the own ideal hard work. I always not forget striving to realize his ideal.

　　Good 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,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 have a dream: To be a doctor.，because doctor may relieve the pain of patients. May let the human change the health. At the same time, I believed that, those who help others may be able to obtain joyfully. Therefore, I hoped in the near future ,I might be a doctor.

　　But I know，life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always comfort us, encourage us ,and support us to move ahead .

　　Young!Fortunately, I am young now. Just due to it, I know that nothing is impossible.I firmly believe that nothing can stand in my way. If I can't realize my dream,it result from that I haven't work harder enough and I won't find other excuses. If no people believe you, you can make it to prove that you are right. If you think the god haven't blessed you and there is no truth here, you can become the god and create the truth.

　　"My breath swallows the sky and make the yellow river overflow, my sword is famous in Kyushu and it can collapse the five sacred mountains." At some time in the past I also had am bitious words and I had some achievements. Each achievement results from my hard work. I always believe that "If you want to have more achievements than others, you must work harder." In some extent, the dream is the hope. If you can insist on doing something, the victory will come.

　　Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today. Let's--- move ----out!

　　Thank you for your listening!

　　Good evening everone

　　My name is .this evening i want to talk something about college life . it include four aspects study,relative ,friendship and love .the first thing i want to say is study. we all have dreams before we enter university,we dream that we can have much more free time and we can improve us according to our advantages ,so we studied hard at junior school and senior school .now we are here in linyi normal university but many of us have no smails on their faces because here is not the place we have been dreaming for. what i want to say is that you can enter a better university to start your heigher education if you studied hard here.so you must calm down and start to study. study is the first thing you must do at university because study can help you achieve you dream.

　　Now,i want to ask some of you a question: where you get your money from? who can answer my question? --------yes we get our money from our parents. this is the second thing i want to say : the relative .our parents paied us here , they give all the things they have so we must respect them and get on well with them ,they also need us just like we need them.apart from our parents we have many other relatives ,they also give us supports, we should respect them and get on well with them too. if we have no relatives we will have no power to study here.

　　When we start to study we meet many new faces which will live with us for four years we must make friends with them .just like the saying says friends play an important role in our life,if you have many fiends you will have less troublts in your life ,if you have no friends you will have troublts everwhere in your life,so do you want to have many friends? of course the answer is ‘yes’.this is the third thing i want to say :the friendship.

　　Love is the last thing i want to say.as far as i can see love is the last thing you do at uiversity.if you fall into the river you will never get out,this does greet harm to your body and your study.besides many people say that love will not give you the sense of sweetness during schoollife.so i do not support on-campus students start their love at university.

　　My deer students,our college life will be richfull if we have planes in our minds.to tell the truth we have little time to stay here our roads are in front .so everone let us start to run toward our roads we have in our mines and we will be the victor in the future!

　　Thank you!
