At first, you must understand the meaning of climate change. It means any long-term significant change in the average weather, which may include average temperature, precipitation, wind patterns and so on. For example, Australia is experiencing rapid climate change. Since the middle of the twentieth century, Australian temperatures have risen by about average one temperature degree with an increase in the frequency of heat waves and a decrease in the numbers of frosts and cold days. Rainfall patterns have also changed, which means that the northwest has seen an increase in rainfall over the last fifty years while much of eastern Australia and the far southwest have experienced a decline. From this example, it indicates climate change that is occurring today has sped up, and affects long-term weather. The Earth’s climate is largely affected by how much heat is stored in the atmosphere. Furthermore, the climate change is caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human activities.
The most important reason of climate change is caused by humans, because humans produce a lot of carbon dioxide into the air. This carbon dioxide emits from fossil fuel, aerosols, cement manufacture, land use, animal agriculture and deforestation. For example, trees can take in carbon dioxide to produce oxygen by photosynthesis. If people cut many trees for making furniture, paper, or sell wood to make money, there is much more carbon dioxide in the air. Beginning with the industrial revolution in the nineteenth century and accelerating ever since, the human consumption of fossil fuels has raised carbon dioxide levels rapidly. It means that carbon dioxide levels are substantially higher now than before. On the other hand, during the procedure of manufacturing cement, which is used in buildings, significantly more carbon dioxide is produced. While people improve their living standard, they cause climate change. When people burn coal, oil, and gas for our electricity, carbon dioxide is produced. When people burn fossil fuel to move vehicles, carbon dioxide is also produced. These sorts of examples indicate that humans are the real culprit. They do not consider the consequence, while they enjoy producing every thing they want.
It is not just man-made pollution of the atmosphere which can cause climate change. Changes in the amount of carbon dioxide in the air have occurred naturally during the history of the Earth, leading to climate changes. When a volcano erupts, it releases huge amounts of carbon dioxide and sulfur dioxide into the atmosphere. However, volcano eruptions cannot effect climate change. The main reason is that before the volcano erupts, it would release huge amount of carbon dioxide and sulfur dioxide for a very long time. This pollution injected into the air blocks out a lot of sunlight. Therefore, it can cause the Earth to cool over fewer years. For example, in April 1991 eruption of Mount Pinatoba, where is in the Philippine islands, emitted huge amounts of carbon dioxide and sulfur dioxide into the air. The movement of the Earth’s axis also affects climate change; it moves a little more than a half-degree each century. Other processes can change the Earth’s climate over millions of years. When not only continents move around the world, but also mountains ranges are built, the changing patterns of landmasses affect the way the heat in the atmosphere and in the oceans is stored. In addition, changes in the way ocean water circulates around the world can affect the climate, because the oceans store even more heat than the atmosphere. Once ocean currents change direction, slow down, or reverse, it has a significant impact on climate.
Climate change is mainly caused by carbon dioxide. This can be separated to two important parts: natural causes, and human causes. After we realise what the two important factors of climate change are, and what the climate change is, we could try to think of a more effective solution to solve the climate change problem to make a higher quality environment.
As you slowly open your eyes, look around , notice where the light comes into your room; listen carefully, see if there are new sounds you can recognize; feel with your body and spirit, and see if you can sense the freshness in the air. Yes, yes, yes, it’s a new day, it’s a different day, and it’s a bright day! And most importantly, it is a new beginning for your life, a beginning where you are going to make new desicisions, take new actions, make new friends, and take your life to a totally unprecedented level! You know all this is real as long as you are confident,passionate and committed! And you are confident, you are passionate, you are committed!
You will no longer fear making new sounds, showing new facial expressions, using your body in new ways,approaching new people, and asking new questions. You will live every single day of your life with absolute passion, and you will show your passion through the words you speak and the actions you take. You will focus all your time and effort on the most important goals of your life. You will never succumb to challenges of hardships. You will never waver in your pursuit of excellence. After all,you are the best, and you deserve the best!
As your coach and friend, I can assure you the door to all the best things in the world will open to you, but the key to that door is in your hand. You must do your part, you must faithfully follow the plans you make and take the actions you plan, you must never quit, you must never fear. I know you must do it, you can do it, you will do it, and you will succeed!
Now stand firm and tall, make a fist, get excited, and yell it out: I must do it! I can do it! I will do it! I will succeed! I must do it! I can do it! I will do it! I will succeed! I must do it! I can do it! I will do it! I will succeed!
Today as the development of the technology people live a much better life than before the average wage is promoted highly. The economy develops at the cost of polluting the environment we can see the pollution everywhere like the river water is dirty the situation is so serious that we must take some action to control the environmental pollution. First we should not throw away the rubbish whenever we have rubbish at hand we should keep the habit to throw it into the dustbin sometimes the garbage can be recycled. Second the government should make some measure to punish the industry which is not deal with the pollution well. With the government’s intervention the businessmen will pay special attention to the pollution and dare not to ignore it. Protecting the environment needs everyone’s effort to ourselves and our offspring’s health we must take action to protect the environment.
今天，随着科技的发展，人们比之前生活得更好，平均工资也大幅度提升。经济的发展却是以污染环境为代价，我们随处可见污染，比如河水很脏，这样的情形是如此的严重，我们必须采取措施来控制环境的污染。第一，我们不应该乱扔垃圾，无论何时我们手中有垃圾，应该养成扔进垃圾箱的习惯，有时候垃圾是可以循环利用的。第二，政府应该采取一些措施来惩罚那么不处理好污染的产业。有了政府的干预，商家就会格外注意污染，不敢忽视。保护环境需要每个人的努力，为了我们和后代的健康，我们必须采取措施来保护环境。
my definition of success
“once upon a time， there was a king who had a daughter as beautiful as a blooming rose. to all the suitors who came to the king's palace to ask for the hand of the princess, the old king
assigned three tasks to be accomplished, each next to impossible. one day, into the king's palace came a handsome young prince...and the ending is always the same, finishing with the line
why aren't we tired of something so fanciful, so unrealistic, and, i would say, so unimaginative? how can a story like that endure generations of repetition`? because, i think, it is a typical succestory. it is highly philosophical and symbolic. by implication, we see a 4-step definition of success:
1 ) a goal to be set. asrepresented by the beautiful princess;
2 ) challenges to be met, as represented by the three tasks; 3 ) the proceof surmounting, as represented by the ordeals the youth goes through; and 4 ) the reward of success, as represented by the happy marriage. the story not only caters to everyone's inward yearning forsuccess, but also emphasizes the inseparability of the proceand the result. the reward of succewill be much amplified if the path leading towards it is treacherous, and vice versa.
if a person inherits his father's millions and leads an easy life, he is not a successfulperson even in material terms, because there are no difficultiesinvolved in his achieving affluence.
good morning,dear teacher and my friends.
it’s a very intresting topic today.
i think my dad was a hero for me when i was a young child. we'd go fishing, walks, and other fun things for a kid.
every child has a good and great father, and so do i. my dad played a very important role in my daily life`````exactly speaking, in my past 16 years.
my father always stands in the center of my life， from past till now and possibly in the future.
my family was rather poor when i was in my childhood. we didn't have our own house and had to live in a shabby， small room rented from my father's factory. the room was so small that there was little space for people to walk. i didn't have my own bed and had to sleep with my parents. this is terrible both for my parents and me.
but father made this all different!he works very hard on his own business, now we have our own 2 housese,surly,i have my own room.and he take our family so much happiness, richer and richer.
when i was little, i did everything with my dad. you could always find me sitting on his knee or walking and doing everything with him. every night he would read me a bed time story and make the voices of each character.
i learnt a lot from my daddy. i learnt to never take things to seriously and to always smile.
like many other fathers, my dad and i also has generation gap. he is not good at or even can’t work the computer. so when i sitting at the computer desk,he will say something like ‘you should pay more attention to your study’, ‘don’t waste time on the computer games’ , ‘it will be bad for your eyes’ and so on. how can i- a computer fan – reduce time on computer? so i continue studying and playing on it
years pasted, my father is over 45 now. it is time for me to look after him and i am sure i will do and we will live an even better life. and i will say,i really love you dad,cause you are the hero in my mind.
thank you so much!
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。
thank you！
What life is abouthttp
htmlAs we all know, the most important thing in life is our attitude towards it, tons of men have tried different ways of treating life, and some succeeded, some failed, and here are some of the tips they left us.
Life isn’t about keeping score. Life isn’t about your shoes or your hair or the color of your skin. In fact it’s not about if you have lots of friends or if you are alone, and it’s not about how accepted or unaccepted you are. Life just isn’t about that.
But life is about whom you love and who you hurt. It’s about how you feel about yourself. It’s about trust, happiness and compassion. It’s about sticking up for your friends and replacing inner hate with love. Life is about avoiding jealousy, overcoming ignorance and building confidence. It’s about what you say and what you mean. It’s about seeing people for who they are and not what they have. And we should always remember to be ourselves. Other might have things that we desire but being what we really are is the only trail leading to the true colors of life. Most of all, it’s about choosing to use your life to touch someone else’s in a way that could have never been achieved otherwise.
The paradox of our time in history is that we have taller buildings but shorter tempers; we buy more but enjoy them less. We’ve learnt how to make a living but not a life, we’ve added years to life, but not life to years. And it is time for us to choose whether to make a difference in our life.
And these choices are what life is about.
People are alarmed by the succession of campus fires in recent years. In each of these accidents heavy casualties were reported – houses were burned down students lost their lives and properties were damaged. Faced with such a chilling fact people keep asking “What on earth results in these repeated tragedies?”
近年来，人们对连续的校园火灾感到震惊。每一个事故中都有严重伤亡报道，房屋被烧毁，学生失去生命，财产受到损失。面对这样一个令人毛骨悚然的事实，人们不禁反问，“究竟是什么导致这些悲剧反复发生?”
A brief survey of them reveals that human factors still prove to be the leading causes. For example three of these fires were caused by the students’ use of electric water-heaters. As students often leave the heaters unattended the risks are rather high should the water in the bottle boil dry while no one is around to turn off the power. In other cases fires were also caused by stoves candles cigarette butts etc.
一项简单的调查揭露，人为因素仍然是主要的原因。比如，其中三起事故都是由于学生使用热得快引起的。由于学生经常让热得快处于无人看守状态，如果瓶中的水烧干却没有人在旁边拔掉电源的话风险是相当高的。其他情况，如火炉，蜡烛，烟头等也会引起火灾。
Since most of these disasters could have been prevented if proper precautions had been taken students should be better educated on the importance and measures of fire control. The following three reminders are of particular importance for us students: First learn how to use a fire extinguisher. Second double-check candles heaters stoves and other electric appliances and make sure there are no open flames before leaving rooms. Lastly do not smoke in the dorm.
因为如果能够采取适当的预防措施，大部分的这些灾难本可以避免的，所以学生应该更好地被教育控制火灾的重要性以及措施。以下三个警告对我们学生尤其重要：第一，学会如何使用灭火器。第二，仔细检查蜡烛，热水器，炉具及其他电器，并确保在离开房间之前没有明火。最后，不要在寝室内吸烟。
As you slowly open your eyes, look around , notice where the light comes into your room; listen carefully, see if there are new sounds you can recognize; feel with your body and spirit, and see if you can sense the freshness in the air. Yes, yes, yes, it’s a new day, it’s a different day, and it’s a bright day!

Stepping into the new century environment pollution has become more serious than ever since. There are different kinds of pollution. Such as water pollution air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. where all these pollution comes from? To a large extend the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street the gas stations are short of gasoline even the government has raise the price so many times in order to control the needs of gasoline but it’s still not working. Overusing the natural resources has already affected the ecological balance. However the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.
进入新世界以来，环境污染比任何时候都要严峻。有各式各样的污染：水污染，空气污染，噪音污染等等。看起来我们活着一个四周都是污染源的星球。那么，这些污染是从何而来的呢?在很大程度上，环境被破坏就是我们为快速的经济增长和人口增加所付出的惨烈代价。为了得到更多的能源，人们砍伐树木，挖更多的煤矿，但是还是难以维持日益增长的需求。不计其数的私家车充斥着公路，加油站的汽油严重短缺，政府多次上调油价也未能阻止私家车对汽油的需求。自然资源的过度利用已经影响到了生态平衡。然而，工厂依旧向外排放有毒气体，把工业废水倒入河里。人们依旧缺乏保护环境的意识。我认为人们应该做些事情了。
The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way our earth could be a better place to live in.
政府应该施行一些更为严格的法律来防止环境被进一步的破坏掉。他们应该让人们了解到保护环境的重要性。我们要在保持经济发展和环境保护中找到平衡点。在沙漠中植树造林，停止砍伐森林。禁止工厂往河流里直接排放废水。鼓励人们用交通工具上班。政府和普通民众都应该携手保护环境，让我们的家园变得干净整洁。只有这样，我们的地球才能更适合人类居住。
Honorable Judges， fellow students：
Good afternoon！
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.
thank you！
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!

Good morning everyone
It's a great honor for me to stand here to deliver a speech to you. Then today I want to talk something about dreams and reality.
As the famous Russian litterateur Lev Tolstoy (列夫、托尔斯泰)said, “Ideal is the beacon(烟火、灯塔). Without ideal, there is no secure (无虑的, 安全的, 安心的, 可靠的, 保险的)direction; without a direction, there is no life.” So there’s no doubt that everyone needs his or her own ideal. Have you ever thought that what is practical and sensible(.明智的, 有感觉的, 明理的) will connect with our most treasured dreams? Maybe, to somebody, reality has little relation to ideal. To others nothing can be done without the sense of reality. So make our dreams a part of our reality. And make our reality a part of our dreams. There is no reason why our dreams must oppose our reality. Improve our dreams and our reality by bringing them together.
As a university student, establishing a dream is one of the most important things we have to do .But everyone must see the reality clearly at first. Your family condition, your personal ability, your social intercourse (交往、交流), your subject and the job you want to do, these things show you the reality and lead you to establish a dream.
Further more, difficult or otherwise, we should put the power of reality into our dreams. Last but not least remember to work hard at the task of chasing 追逐our dreams. Do believe that we can achieve our ideal step by step by the passage of time!
In the end, I want to share with you a poetry named " I think I can".
Maybe you can not understand the meaning of the poetry , But do not be worried ,Let me tell you the meaning
Thank you for your listening!
