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.
good morning/evening/afternoon， ladies and gentlemen ：
today， my speech is about talents，in my opionion， talents are indispensable in nowadays society. as is known to all that the fight among countries is actually the fight among talents.
first， i＇d like to define the word＂talent＂ in my idea， a talent is one person who is good at or expertised in some or multiple areas. nowadays， as the world developing goes on ， if one country want to rank top or do a good job in the world， the country must have many example， china， the biggest developing country in the world， in the past 100 years， is always invaded by other countries， why ，the reason is that china at that time had not so many talents. if they had anti-intrusion leader talents in the war， needleto say，they would have beat those big they had talents in weapons manufacturing， nodody dares to provoke ver， nowadays， it＇s a totally different situation， china has become powerfulin all over the world， why ？ because there are many talents serving the country， the civilians become more and more and more people go to university，more and more people come to receive further education. so what is that in return，talents in army protect our country from invasion， talents in commerce help make our economy keep in improving， talents
in aerospace make the world see chinese manned spacecraft flying. talents in sports make china rank the first in the olympic games......
to sum up， talents will play a more and more impoetant role in the world， if one country intends to flourish， he must foster talents as many as they can ，that＇s all。
thank you！
Today, my speech is about talents,in my opinion, talents are indispensable in nowadays society. as is known to all that the fight among countries is actually the fight among talents. First, i'd like to define the word"talent" in my idea, a talent is one person who is good at or expertised in some or multiple areas. nowadays, as the world developing goes on , if one country want to rank top or do a good job in the world, the country must have many talents.for example, china, the biggest developing country in the world, in the past 100 years, is always invaded by other countries, why ,the reason is that china at that time had not so many talents. if they had anti-intrusion leader talents in the war, needless to say,they would have beat those big powers.if they had talents in weapons manufacturing, nodody dares to provoke us.however, nowadays, it's a totally different situation, china has become powerfulin all over the world, why ? because there are many talents serving the country, the civilians become more and more literated.more and more people go to university,more and more people come to receive further education. so what is that in return,talents in army protect our country from invasion, talents in commerce help make our economy keep in improving, talents in aerospace make the world see chinese manned spacecraft flying. talents in sports make china rank the first in the olympic games……
To sum up, talents will play a more and more impoetant role in the world, if one country intends to flourish, he must foster talents as many as they can ,that's all,thank you.
A minute does farm work, a minute harvest! So long as usually is unceasing diligently and the unceasing accumulation, when test certainly can paat one fell swoop, does not have the pain paying, has how possibly has harvests?As the saying goes that, The "study is the lamp, the endeavor is the oil, must think the lamp is bright, must refuel. "hits a inappropriate analogy in, is diligent is just like diligently military practices narrow and small to say" Yi Jinjing ": Regardleof how clumsy method, so long as matches by diligently diligently, surely may "decayed be mysterious", thus obtains the considerable result, therefore I always believed, the study is first must be diligent definitely, any side Buddhist-nature, 策略性 the thing left has been diligent without knowing where to begin mentions.
Did not have inadequately to recognize is studies in the proceindeed to have some 技巧性 thing, the Heaven all has indeed prepared set of best studies methods and the strategy for each people, only our very many people had not found these skills, the method, the strategy.
The "knowledge, the knowledge, partly depending on study, one partly depends on asked. "this is a truth absolutely. Is for gain admission to a good university in the high school three years, but and is said the student does not have the free development completely the space, so long as under student or have the plan in parents’ instruction to arrange own study and the life, plans own extra-curricular development, this also is the study strategy.
How regardleof the environment, a "minute does do farm work, a minute harvest, the" only diligent rest, the striving to improve upward person only then cannot finally succeed!
good morning everyone
it's a great honor for me to stand here to deliver a speech to you. thentoday 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 thebeacon(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 thateveryone needs his or her own ideal. have you ever thought that what ispractical and sensible(.明智的, 有感觉的, 明理的) will connect with our most treasureddreams? maybe, to somebody, reality has little relation to ideal. to othersnothing can be done without the sense of reality. so make our dreams a part ofour reality. and make our reality a part of our dreams. there is no reason whyour dreams must oppose our reality. improve our dreams and our reality bybringing them together.
as a university student, establishing a dream is one of the most importantthings we have to do .but everyone must see the reality clearly at first. yourfamily condition, your personal ability, your social intercourse (交往、交流), yoursubject and the job you want to do, these things show you the reality and leadyou to establish a dream.
further more, difficult or otherwise, we should put the power of realityinto 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 thepassage 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 beworried ,let me tell you the meaning
thank you for your listening!
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！
I love you,China
Good morning, ladies and gentlemen, I’m very glad to make a speech here. Today my topic is “I love you, China.”
Since the day I was born, I began to have a proud name—Chinese. Since the day I began to talk, the most beautiful sentence I’ve ever learnt has been “I love you, China!”
I love you, China, and I’m so proud of being a Chinese. I’m proud that I’ve got the beautiful yellow skin, black eyes and black hair. I’m also proud that I speak the most beautiful language in the world—Chinese.
I love you, China, for I can feel the deep love you give me every day, every minute. Last year, I got an opportunity to visit the United States of America. During my staying there, my father’s boss once invited my family to dinner. While at , he looked at me and asked: “Little boy, how long have you been in America?” “About a month,” I answered, “How lucky you are!” he said, “If you were living in China, how could you learn such perfect English?” I smiled and told him proudly that all the students in China are able to learn English at school. I saw his surprised eyes and said to myself, “I’m proud of you, China ”

youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the
emotions : it is the freshne; it is the freshneof the deep springs of life .
youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. this often exists in a man of 60 more than a boy of 20 . nobody grows old merely by a number of years . we grow old by deserting our ideals.
years wrinkle the skin , but to give up enthusiasm wrinkles the soul . worry , fear , self –distrust bows the heart and turns the spirit back to dust .
whether 60 of 16 , there is in every human being ‘s heart the lure of wonders, the unfailing childlike appetite of what’s next and the joy of the game of living . in the center of your heart and my heart there’s a wirelestation : so long as it receives messages of初中英语演讲稿beauty , hope ,cheer, courage and power from men and from the infinite, bfanwen.com so long as you are young .
when the aerials are down , and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80.
thank you!
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！
