Good evening ladies and gentlemen, today I am more than honored to be here to share with you some of my thoughts about the famous sentence said by Steve Jobs, “The people who are crazy enough to think they can change the world are the ones who do.”

Recently I have just finished watching a Japanese animation named 世界征服 , which means conquering the world. The little girl in the middle stopped growing up the minute she decided to conquer the world. She had many followers, and of course there were also many people who regarded her dream to conquer the world as a silly kid’s game. However, no matter what others thought about her, she never said a word about giving up. That was her own dream, and it could never be changed by anyone. In the end, she finally fulfilled her dream. I still remember one sentence that she shouted to her enemy, “I’ll go and meet every single person in the world, I’ll talk to them, men or women, youth or elderly, if I can’t even do this tiny thing, what qualification would I have to conquer the world?!” It sounds like a silly thought, but I was greatly moved by it. Indeed, in many cases, others may despise our dream, we may be looked down upon, we may be excluded from the crowd, but how many of us can firmly stick to our dreams, never letting go? In most cases, we gave up; therefore we couldn’t become those great people who change the world.

This is a world full of wonders, no matter what happens, this world always shines brightly like a jewel. Every day, the world waits for new people to give it a change. The person who changes the world can be Superman, Spiderman, batman, but more commonly, they are common people with no superpowers. To be that person, the first step is to believe that you can change the world. Changing the world was never a tremendous task. It could be something just tiny. If you switch from driving to walking to work, you changed the world by making the air cleaner. If you published your own book, you changed the world by enriching its idea storage. If you designed a new digital product, you changed the world by adding variety to it. You see, to change the world is truly practical. So why not crazily dream to change the world? Though your change may be very small and can be seen by few or even no people, it is still a valuable dream. Small changes don’t appeal at first, but what if many small changes come together? It would be a big difference. Therefore, it is always meaningful to have changing the world as a dream.

Now close your eyes and trace back to your childhood, I suppose that many of you have once had the thought of changing the world. Do you still believe in that now? Are you still making efforts to realize that? Think about these questions frequently, and all I want to say is, keep dreaming, and change the world in your way. Thank you.

第二篇：演讲稿

Ladies and Gentlemen:

I am very pleased to be at this meeting and exchange views with you. I would like to take this opportunity to introduce the situation of climate change and make some advice on the tackling of climate change. International society should strengthen dialogue and cooperation on climate change.

In recent decades, climate change is becoming an increasingly serious problem of the whole world, especially the global warming. Global warming is an increase in the earth’s temperature due to fuels, industry, and the destruction of forest. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth’s atmosphere and warms its surface, while long-wave infrared radiation emitted by earth’s surface is absorbed and then re-emitted by trace gases.

The arctic region is a bone-chilling,uninviting place to live for people.For polar bears,it is perfect or it was. The bear,s icy home is melting.Some scientists estimate that much of the arctic will be ice-free in summer by the year 2100.Global warming is not just happening in the Arctic,the whole world,s climate is changing.Global warming also leads to the rise of sea levels.Chinese coastal regions would gradually disappear with rising sea levels. Global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms.Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years.

Climate change occurs naturally,but now people are ceasing it or at least speeding it up.The earth’s temperature is rising at an accelerating rate.Scientists believe that our use of fossil fuels ceases global warming.

In the past,,animals could adapt to gradual climate change by modifying behavior.Today,environmental pressures from growing human population,along with the faster rate of climate change,make survival for many animals a big challenge.This gives rise to the decrease of biological diversity.

It is imperative for us to take effective measures to crack this hard nut. First and foremost, governments should pour more investment into the research and development of new energy in a bid to make the earth more comfortable for us to live in. Furthermore, relevant laws and regulations should be made to postpone climate change.Last but not the least,a world-wide education campaign should be launched to cultivate people,s environmental protection sense. Only by doing so can we surmount this difficulty.

Thank you!
