what is nature? its everything that exists in the world independently of people， such as pants and animals， earth and rocks， and the weather.
now more and more people are focusing on the nature. it is no doubt that the nature is important to every human being. no nature， no life. because of the supplies of the nature， we have lived happily for a long time. and we started to gain every thing available from the nature. and this lasted so long a time. today， people have discovered that the nature around is getting worse and worse.
what is threatening the nature? air and water pollution， overharvesting of plant and animal species， overpopulation and so on. overpopulation is the biggest source of pollution. lets take overpopulation as an example.
what does overpopulation feel like? when we move slowly through the city in a tazi. when we enter a crowded slum district. when the temperature is high and when the air is thick with dust and smoke. the streets are crowded with people. the streets seem alive with people. people eating. people washing. people talking. people sleeping. people visiting each other， arguing and screaming. people relieving themselves. people pushing their hands through the taxi windows， begging. people leading animals. people， people， people， people. as we drive slowly through the crowd， sounding the taxis horn， the dust， heat， noise and cooking fires made it like a scene from hell! i admit， frightening.
to the nature， overpopulation is a big problem. more people， more pollution. and the big population is threatening the nature every second.
the rapid rise in world population is not creating problems only for the developing countries. the whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase. people in rich countries make the heaviest demands on the worlds resources， its food， fuel and land， and cause the most pollution. a baby born in the united states will use in his lifetime 30 times more of the worlds resources than a baby born in india. unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land， food and fuel， and the future will bring poverty， misery and war to us all.
for most of the developing countries， it is a good idea to control the population growth. for example， china has carried out birth control for years. and this plan has a GREat effect on the world population.
if the population continues to increase， if the air and water continue to be polluted， if we dont do something to protect wild-plant and wildlife species will be declining. species and biological communities have difficulty adapting to change. economic opportunities and the quality of life of future generations are also put at risk. by protecting nature， we protect ourselves.
lets unite together， hand in hand we stand all across the land.
we can make this world in which to live. hand in hand. control the population growth. take good care of our nature.

good evening ，ladies and gentlemen：
thank you very much for choosing to e in such a cold night。today my topic is about choice and process。a research shows that a man has to make 73 choices one day。with so many choices one day， people easily get so confused and afraid of making wrong choice that they hesitate and finally miss the true part of life。 in my opinion， the following part is of much more importance than the choice。 there is no absolute right or wrong choice but wonderful or boring life， which the process makes the difference。
life is a box of chocolate，you never know what you will get。 forrest gump made no decision by and for himself but he acplished great success with his strong will in the process。 the process is not the road itself but the attitudes and feelings ，the caution， courage and persistance we have as we encounter new experience and unexpected obstacles。 take myself as an example， i changed my major when i became a postgraduate。 after the choice，days have been harsh for me。i cannot understand the new lessons at all。 for they are closely related to mathmatics which i learned nothing about before。 however wuth the belief that this is the great chance for me to experience new ideas and challenge myself，i persisted。 i asked for help from every channel and reorgonized my life。 gradually i could understand some parts and even found maths interesting。moreover， i learned to act instead of plaining。 in retrospect，the choice left no trace in my mind but the happiness and bitterness of the past four months bees an unforgetable experience in my life。
no matter what the choice is， enjoy the process。 in the process， your potential will be inspired and new discoveries，improvement and progress will e to you。 these are the most beautiful sceneries and only on the way can you see it。these make your life colorful。
there is no need and i donnot want to judge whether it right or wrong for me to be here，but i congratulate to myself for i gain and enjoy this fantastic experience。 so my dear friends，never worry about your choice and enjoy the process。 i am sure you will get something new and intersting tonight after you chose to e here。
Honorable Judges， fellow students：
Recently， ther is a heated debate in our society. The college students are the beneficiaries of a rare privilege， who receive exceptional education at extraordinary places. But will we be able to face the challenge and support ourselves against all odds? Will we be able to better the lives of others? Will we be able to accept the responsibility of building the future of our country?
The cynics say the college students are the pampered lost generation， which would cringe at the slightest discomfort. But the cynics are wrong. The college students I see are eagerly learning about how to live independently. We help each other clean the dormitory， go shopping and bargain together， and take part time jobs to supplement our pocket money.
The cynics say we care for nothing other than grades; and we neglect the need for character cultivation. But again， the cynics are wrong. We care deeply for each other， we cherish freedom， we treasure justice， and we seek truth. Last week， thousands of my fellow students had their blood type tested in order to make a contribution for the children who suffer from blood cancer.
As college students， we are adolescents at the critical turning point in our lives. We all face a fundamental choice： cynicism or faith， each will profoundly impact our future， or even the future of our country. I believe in all my fellow classmates. Though we are still inexperienced and even a little bit childish. I believe that we have the courage and faith to meet any challenge and take on our responsibilities. We are preparing to assume new responsibilities and tasks， and to use the education we have received to make our world a better place. I believe in our future.
Failure is what often happens.it is everywhere in your life.students may fail in exams, science may fail in their researchwork,and athletes may fail in competitions.
although failure happens to everyone, attitudes towards failure are various. some people don't think their failure is a very important thing at all. so they pay no attention to it. as a result, they will have the same failure a previously later.they spend their thime and energy on useless things and they may really be fools as they have thought.
Success is not easy to talk about because the word success it-self has hundreds of definitions. For some it means power, for some it means wealth, for others it is fame or great achieve-ments. But I have my own understanding of it.
Success means to try your best.
Many people believe that success means to win. In my opin-ion, it means to try your best when you do everything, no matter you will win or not. When you are taking part in a long-distance race, if you keep on running as fast as you can, you are successful, although you may be the last to pass the finishing-line. Because you have showed your best to others, and you have made I your greatest effort to be the winner.
Success means to work hard.
No one can succeed without any hard work. Karl Max was successful, because he spent more than 30 years writing the book "Communist Manifesto"; Tomas Edison succeeded, because he had experimented thousands of times to find the best material for lights. Every success calls for hard work. If you want to suc-ceed, work hard first.
other people are quite different from the two kinds of people mentiond above. instend of being distressed and lost,they draw a lesson from every failure and become more experienced. after hard work, they will be successful in the end. It is said that failure is the mother of success. success will be gained after times of failures so long as we are good at drawong lesson from our failures.
in my opinion , failure is not a bad thing , the really bad thing is taking a failure as failure or even lose our heart after failure.
More importantly, today, the world is undergoing fast rhythm of changing, some issues occur in one way this time and reoccur in another way that time.Such instability and inconstancy make many long-time-lasting conventions and traditions not valid any longer. People encounter pile of new conditions everyday in current society, it is hard to find adequate reference from the wisdom of conventions for all of these new thing, what can really lead people to success is rational mind and creative ways of thinking. To meet the requirement of new missions, only creative activities could give out adaptive strategies. Without creative thinking ways, there would no such increasingly development of science and technology in the past two centuries, no new type America-style democracy in the world, no so many products making modern life so comfortable and convenient. Creative practices and original idea are the engine of the fast development of modern life, and are most essential for people to accomplish successful achievement in all kinds of fields.
