It is undeniable that the worsening environment has bee the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion. Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say that deterioration of the quality of the environment threatens the existence of mankind itself.
Some people are of the opinion that the environmental problem is the price we have to pay for economic development. But I do not think that this argument is valid. After all, what is the point of economic growth if people’s lives are adversely alfected by worsening environmental pollution?
There is plenty of evidence to show that sustainable development can be achieved by balancing economic growth with protection of the environment. The key to achieving this is to make people aware of the seriousness of the problem. Both governments and ordinary citizens should join hands to make this world a better place to live in, not only for ourselves, but also for future generations.
不可否认的是环境恶化已成为当今世界上人们最担心的事了。因为水资源的浪费和土壤被侵蚀，土地资源逐渐缩小。我们呼吸着有毒的空气，河流和湖泊也被附近的工厂里排放出来的废弃物严重污染了。不夸大其词地说，环境质量的恶化很可能威胁人类的生存。
有些人说环境问题是我们为经济发展所付出的代价。对此，我不敢苟同。如果人类的生活被日益恶化的'环境污染所影响的话，那么，经济发展的好处何在？
足够的证据证明:经济发展与环境保护的平衡能够实现可持续发展。关键是使人们意识到问题的严重性。政府和普通市民两方都就应携手使地球成为更适合人类居住的地方，这不仅仅是为我们自我，也是为我们的后代。
As you heard earlier, just over on that side of Killian Court, showing off their spectacular red jackets are more than 170 members of the class of 1969. Apollo 11, as you heard, landed on the moon a few weeks after their MIT graduation. A number of them went on to work in fields that were greatly…greatly accelerated by progress from Apollo 11. One of them is Irene Greif, the first woman to earn a PhD in computer science from MIT.
But I believe our 1969 graduates might all agree on the most important wisdom we gained from Apollo: It was the sudden intense understanding of our shared humanity and of the preciousness and fragility of our blue planet.
50 years later, those lessons feel more urgent than ever, and I believe that, as members of the great global family of MIT, we must do everything in our power to help make a better world. So it is in that spirit that I deliver my charge to you.
I’m going to use a word that feels very comfortable at MIT, although it has taken on a troubling new meaning elsewhere. But I know that our graduates will know what I mean.
After you depart for your new destinations, I want to ask you to hack the world until you make the world a little more like MIT – more daring and more passionate, more rigorous, inventive and ambitious, more humble, more respectful, more generous, more kind.
And because the people of MIT also like to fix things that are broken, as you strive to hack the world, please try to heal the world, too.
Somebody says"Time is money".But I think time even more important than money.Because when money is gone,we can get it back.But when time is gone,it'll never be back.
Every day we have 24 hours.We sleep,we have meals and we rest.They are necessery and will take a lot of time.Then how can we spendthe rest of the time?
Someone do the reading,do exercises and learn a lot of things.They never waste(浪费）any time.They live happily and healthily.
However,someone just waste hour after hour doing nothing useful.They get up very late.They spendall day playing computer games.They hate to learn knowledges.Don't they know that they are wasting part of their own lives?
So please,please save time for ourselves,Our life is limited（有限）,and remember:we have no time to lose.
Hello, schoolmates and teachers. Good afternoon, everybody! I'm Pang Qiyuan, from Class 2, Senior 3. Today I'm very happy here to talk about my dream. I hope you can support me and do me a favor, OK? Dream likes a beautiful flower. Different people have different dreams.They make the earth colorful and wonderful. A dream is a target in life, in which it can give people power. It can show people the directions and final destinations. I have three dreams. My first dream is that I wish I could go to college some day, which is also the one of many other students' dreams. Going to college for further education can not only enrich our knowledge, but also teach us how to behave better. I always imagine that the college life must be very interesting. This dream gives me energy to study harder and harder. Now I'm trying my best to make it come true. Sure, I have enough confidence to realize my dream. My second dream is becoming an excellent doctor. I always dream that I could turn a doctor like Bai Qiuen, so that I could cure a lot of patients, help them get rid of sick devil, let them lead a healthy and happy life, and finally I will feel happy, too. My third dream is that all the people together with the surroundings can live in perfect harmony. There are no quarrellings, no cheatings, and no wars in the world. We should be kind to each other, love each other and care each other. All the people in the world could get along as well as a big family with each other. I dream that we could enjoy absolute peace and freedom. These are my dreams. How I wish that they could come true soon! Thank you.
