首先，我想知道，你的命運給你什麼?幸福，智慧，一個強壯的身體或者其他東西。如果我有問這個問題，尼克松總統，他可能會說，“命運給予我們的不是失望之酒，而是機會之杯。”
不用說，中國的一個最大的機會是20xx年奧運會。直到現在，我們已經使用2/7的準備時間。你看過多少變化?新的道路，新的地鐵線路，public-exercising裝置用美麗的色彩，大量的草地上，大量的現代健身房正在建設。
以外，有更加好的效果帶給我們不能直接看到的奧運會。例如，越來越多的人瞭解中國。我相信神祕的中國文化會強烈吸引他們。和奧運會也將做良好的經濟和環境，因為這是獲得外國投資者的關注和保護環境的意識正在加強。更重要的是，奧運會給一個獨特的機會來激勵和教育新一代的中國青年奧林匹克精神和奧林匹克精神。現在，我們已經看到這麼多的進步，你能想象我們失去控股權利?
我已經說了很多關於奧運會和中國。但我認為每個人都應該用一些時間來思考這個問題，“奧運會有什麼特殊意義嗎?”
對我們來說，我的意思是中國青年，20xx年奧運會是一個巨大的禮物。因為我們正在等待做一些重要的是償還給我們的愛。社會就像一艘船，我們的夢想隊長揮舞著他的手，說：“嘿!來這裡和掌舵!“他的聲音有多迷人，但我們從未聽說過它在我們的真實生活。然而今天上午，當我們醒來時，我們將看到奧運會揮舞著它的手。咀嚼後，我們大多數人至少都會有一個計劃為奧運會做什麼。和我的是一個“被子”——這是會安慰別人的人。
在我演講的最後，我希望所有的準備工作將順利，每個人都向世界展示他們的能力。讓我們抓住機遇，給挑戰一個燦爛的微笑。
First, I would like to know, what does your destiny offer you? Happiness, wisdom, a strong body or something else. If I had asked this question to president Nixon, he would probably had said,”Our destiny offers not the cup of despair, but the chalice of opportunity.”
Needless to say, one of the biggest opportunities given to China is the 20xx Olympic Games. Till now, we have used two sevenths of the preparation time. How much changes have you seen? New roads, new subway lines, public-exercising equipments with beautiful colors, large blocks of grass fields, and also lots of modern gyms which are under construction.
Other than those, there are even more good effects brought to us by the Olympic Games that cannot be seen directly. For example, more and more people will get to know China. I’m sure the mysterious Chinese culture will attract them strongly. And the games will also do good to the economy and environment, for it is gaining the attention of foreign investors and the awareness of environmental protection is being strengthened. What is more, Olympic Games give a unique opportunity to inspire and educate a new generation of Chinese youth with the Olympic values and the Olympic spirit. Now that we have seen so many advances, could you even imagine us losing the holding rights?
I’ve already said a lot about the Olympics and China. But I think everyone should use some time to think of this question, ”Does the Olympic Games have any special meaning to you?”
For us, I mean the Chinese youth, 20xx Olympic Games is a tremendous gift. Because what we are waiting for is to do something significant as repaying the love given to us society is just like a ship, and in our dreams the captain is waving his hand and saying ”Hey! Come here and take the helm! ”How charming his voice is, but we have never heard of it in our true life. This morning, however, when we wake up, we will see the Olympic Games waving its hand. After chewing, most of us will have at least one plan about what to do for the Olympic Games. And mine is to be a “comforter” ----that is someone who will give comfort to others.
At the end of my speech, I hope all the preparation will go well, and everyone will show their ability to the world. Let us seize opportunities and give a big smile to challenges.
今天每個人都知道，英語是非常重要的。它已經被應用到世界的各個角落。它已成為最常見的語言網路和國際貿易為。如果我們能說好英語，我們就有更多的機會成功。因為越來越多的人注意到，去學習英語的人的數量增加了高速。
但對於我自己，我學習英語不僅因為它的重要性和它的實用性，更是因為我對它的愛。當我學英語時，我能感覺到一種不同的思維方式給我更多接觸世界的空間。當我讀英語小說時，我能感受到不同於閱讀的快感從這本書的翻譯。當我說英語時，我可以感到自信從我的文字裡。當我寫英語時，我可以看到不一樣的美麗我們的中國……
我愛英語，它給了我一個色彩斑斕的夢。我希望有一天我能環遊世界。和我流利的英語，我可以和很多來自不同國家的人交朋友。我能看到許多的名勝。我夢想我可以去倫敦，因為它是英語的出生地點。
我也想用我流利的英語介紹我們偉大的地方英語為母語的人們，我希望他們可以像我們一樣的愛我們的國家。
我知道，羅馬不是一天建成的。我相信，經過不斷的努力學習，有一天我能說英語很好。
如果你想要被愛，你應該學會去愛別人，並讓自己可愛。所以我相信像我愛英語每天，它也會愛我。
我相信總有一天我會實現我的夢想!
謝謝你們!
As everyone knows，English is very important has been used everywhere in the has become the most common language on Internet and for international trade. If we can speak English well，we will have more chance to use more and more people have taken notice of it，the number of the people who go to learn English has increased at a high speed.
But for myself，I learn English not only because of its importance and its usefulness，but also because of my love for I learn English， I can feel a different way of thinking which gives me more room to touch the I read English novels，I can feel the pleasure from the book which is different from reading the I speak English， I can feel the confident from my I write English，I can see the beauty which is not the same as our Chinese...
I love English，it gives me a colorful dream.I hope I can travel around the world one day. With my good English， I can make friends with many people from different contries.I can see many places of great intrests.I dream that I can go to London，because it is the birth place of English.
I also want to use my good English to introduce our great places to the English spoken people，I hope that they can love our country like us.
I know， Rome was not built in a day. I believe that after continuous hard study， one day I can speak English very well.
If you want to be loved， you should learn to love and be lovable. So I believe as I love English everyday ， it will love me too.
I am sure that I will realize my dream one day!
Thank you!
今天，我的演講是關於人才，在我看來，人才在當今社會是不可或缺的。眾所周知，國家間的鬥爭實際上是人才之間的戰鬥。
首先，我想定義“人才”這個詞在我的想法，才能是一個人誰是擅長或公司部分或多個領域。如今，隨著世界發展，如果一個國家想要排名頂部或世界上做得很好，國家必須有很多人才。例如，中國，世界上最大的發展中國家，在過去的120xx年裡，總是被其他國家的入侵，當時為什麼，原因是中國沒有如此多的人才。如果他們anti-intrusion戰爭領袖人才，不用說，他們會打敗那些大國。如果他們在武器製造人才，nodody敢惹我們。然而，如今，這是一個完全不同的情況下，中國已成為全世界powerfulin，為什麼?因為有很多人才服務於國家，平民越來越有文化。越來越多的人上大學，越來越多的人開始接受進一步的教育。在軍隊是什麼，作為回報，才能保護我們的國家免受入侵，人才在商業的幫助使我們的經濟保持改善，人才航空讓世界看到中國載人飛船飛行。人才在體育在奧運會上讓中國排名第一……
總之，人才將起到越來越impoetant在世界上的角色，如果一個國家想要蓬勃發展，他必須儘可能多培養人才，這是所有，謝謝你。
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 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 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 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，隨著科技的發展，人們比之前生活得更好，平均工資也大幅度提升。經濟的發展卻是以汙染環境為代價，我們隨處可見汙染，比如河水很髒，這樣的情形是如此的嚴重，我們必須採取措施來控制環境的汙染。第一，我們不應該亂扔垃圾，無論何時我們手中有垃圾，應該養成扔進垃圾箱的習慣，有時候垃圾是可以迴圈利用的。第二，政府應該採取一些措施來懲罰那麼不處理好汙染的產業。有了政府的干預，商家就會格外注意汙染，不敢忽視。保護環境需要每個人的努力，為了我們和後代的健康，我們必須採取措施來保護環境。
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?”
近年來，人們對連續的校園火災感到震驚。每一個事故中都有嚴重傷亡報道，房屋被燒燬，學生失去生命，財產受到損失。面對這樣一個令人毛骨悚然的事實，人們不禁反問，“究竟是什麼導致這些悲劇反覆發生?”
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.
一項簡單的調查揭露，人為因素仍然是主要的原因。比如，其中三起事故都是由於學生使用熱得快引起的。由於學生經常讓熱得快處於無人看守狀態，如果瓶中的水燒乾卻沒有人在旁邊拔掉電源的話風險是相當高的。其他情況，如火爐，蠟燭，菸頭等也會引起火災。
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.
因為如果能夠採取適當的預防措施，大部分的這些災難本可以避免的，所以學生應該更好地被教育控制火災的重要性以及措施。以下三個警告對我們學生尤其重要：第一，學會如何使用滅火器。第二，仔細檢查蠟燭，熱水器，爐具及其他電器，並確保在離開房間之前沒有明火。最後，不要在寢室內吸菸。
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.
進入新世界以來，環境汙染比任何時候都要嚴峻。有各式各樣的汙染：水汙染，空氣汙染，噪音汙染等等。看起來我們活著一個四周都是汙染源的星球。那麼，這些汙染是從何而來的呢?在很大程度上，環境被破壞就是我們為快速的經濟增長和人口增加所付出的慘烈代價。為了得到更多的能源，人們砍伐樹木，挖更多的煤礦，但是還是難以維持日益增長的需求。不計其數的私家車充斥著公路，加油站的汽油嚴重短缺，政府多次上調油價也未能阻止私家車對汽油的需求。自然資源的過度利用已經影響到了生態平衡。然而，工廠依舊向外排放有毒氣體，把工業廢水倒入河裡。人們依舊缺乏保護環境的意識。我認為人們應該做些事情了。
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.
政府應該施行一些更為嚴格的法律來防止環境被進一步的破壞掉。他們應該讓人們瞭解到保護環境的重要性。我們要在保持經濟發展和環境保護中找到平衡點。在沙漠中植樹造林，停止砍伐森林。禁止工廠往河流裡直接排放廢水。鼓勵人們用交通工具上班。政府和普通民眾都應該攜手保護環境，讓我們的家園變得乾淨整潔。只有這樣，我們的地球才能更適合人類居住。
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 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.
The world changed when James Watt invented the first steam engine, when Isaac Newton discovered the universal gravitation after hit by an apple, when Karl Marx wrote The Communist Manifesto, when Chairman Mao solemnly declared the establishment of the People's Republic of China on the Tian'anmen Rostrum, when Martin Luther King cried out “I have a dream”. The world was changed by something called dream, which is invisible, untouchable but strong enough.
I can assure that every child have written a composition titled My Dream. They have already written down their longing for the future. Some of them want to become scientists; some of them hope to become teachers or doctors. Maybe they didn’t know how many difficulties they will face before their dream come true. But the dreams are like small seeds planted in their hearts; like the beacon in the sea that lead them to their destinations.
Dream is the fountain of strength. Dream is the support of faith. Dream is the Polaris. Dream reminds us to move forward, to struggle, to strive all the time. One of my friends told me that dream will never discard anyone! Yes, maybe one day everything is gone but dreams is still there with you, eternally.
Dream changed us, and therefore we changed the world. It is dream that refreshes the world every day. It is also dream that makes the world improve day by day. We dare to dream. We can also achieve our dreams and change the world.
I can’t imagine the world without dreams. How about 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 ”
Hello everyone.

Good afternoon, ladies and gentlemen, Today I'm going to talk about sandstorm.
Sandstorm is a kind of bad weather witch is becoming increasingly common in Northwestern China, and it usually happens in spring and fall. Though I'm only 13, I have experienced it and suffered from it quite a lot.
I'm sure most people still remember the sandstorm that happened last month. It swept across the large area of 11 provinces and caused a great loss to our nation.
As you can see on TV, when a sandstorm comes, the wind blows strongly with dust and sand. Sometimes trees are even broken down in half, and little birds cannot find their homes. Sometimes clouds of dust blur the vision, and little kids cannot find their ways. It's like the end of the world.
When a sandstorm occurs, our classroom is filled with dust and sand. My poor teachers! They've breathed in enough chalk-powder. Now, they have to take in much dust. My poor fellow classmates! They told me they were almost dying.
We love beautiful spring. We cherish bright sunshine. But sandstorms destroy all the lovely things. Yet we know it is Mother Nature's revenge on what we have done to her. In order to see blue sky and sunny spring again, we should plant more trees and more grass to protect the environment. And it is not too late if we start right now.
Though it's a hard job to fight against the sandstorm, it is the battle we must fight, and it is a battle we must win!
Thank you!

Dear friends! Do you still remember your first English teacher? You may say:“ Yes.” Everyone has his teachers, in my mind, I'll never forget her ------my first English teacher Ms. Li. Without her, I wouldn't be standing here. She is a young and lovely lady with beautiful eyes. Her voice sounds sweet and she speaks English very well. That was the first impression she left on us when she first gave us an English lesson.
In her class, she taught us carefully and patiently. She always made opportunities for us to speak English. She gave us many beautiful pictures to talk on them, played games with us and told us many interesting stories. Little by little, I had interest in English, but English was a new subject to me, I had many difficulties in learning it well. I often felt very confused. It was Ms. Li who helped me to find ways to overcome my difficulties. She helped me to practice speaking English everyday. She always encouraged me whenever I lost heart. She helped me to have confidence in myself. She gave me what I needed, courage, confidence, good ways to learn English and opportunities to speak English in class. So I was grateful for her. Maybe I can't meet her again. The only thing I can give her is my best wishes. I wish my dear teacher happiness, good health and good luck. And I also want to say to her: Thank you, Ms. Li. I love you!
Here are the beacon tower, also known as beacons, Wolf yantai. Independent buildings is not connected to the Great Wall. Once the enemy pounce, communicate its kindle wars and light smoke during the day is called "ran, called flint fire at night. When the Ming dynasty, also on the relationship between the war with the enemy made a strict rules: the enemy hundreds, burning a smoke point a gun; Five hundred people, burning two smoke point two guns; More than one thousand people, three smoke SAN pao; More than five thousand people, four smoke four guns; More than ten thousand people, five five gun smoke. In this way, on the border of the military intelligence can rapid transfer to the imperial city ouchi. See the beacon tower, and then tell you a story, called "must play leud" : the zhou dynasty had a king named weeks you king, he has a beautiful woman, her temper is very strange, always don't smile, think of some way to you king. He lit up a distress signal (fire), as a result, drew leud come white, she laughed, you king is also very happy. But, really have an enemy to attack, you king lit the fire, but no one come, and he was killed by the enemy. There is a story, called "meng jiangnu cry Great Wall collapse" : legend was Meng Gusheng a daughter named meng jiangnu. Because of qin shi huang to build the Great Wall, need a lot of manpower. Qin shi huang was caught many people go to the Great Wall.
All of a sudden, I do not know where to come up to a rumor: only the wan xi is buried under the Great Wall, can make the Great Wall and solid, qin shi huang was, sent people seize wan xi. Wan xi good fled to Bangladesh. People see wan xi meng home good handsome, talented, good let meng jiangnu and wan xi of their marriage. The two men marry less than 10 days, good wan xi is the rulers who grasp to go to repair the Great Wall. In the fall, meng jiangnu saw her husband hasn't come back, give him the woolies. Along the way, reject, hardships, day and night, all the way to the Great Wall. Local people told her: wan xi good would have buried under the wall. She was grief-stricken, crying. Instantly, and dark, the Great Wall was crying collapsed in eight hundred. Just then, qin shi huang to have the Great Wall, with fine features, when he saw meng jiangnu just want her to do concubine. For qin shi huang meng jiangnu agree to her three conditions: one is for wan xi is a grave; The second is to make good full chao wenwu festivals wan xi; Three is in the middle of the Great Wall and the tomb of wan xi good repair a like flying grand bridge. After three things done, she threw herself into the sea.
Visitors, this is three stories about the Great Wall. Now the Great Wall tourist stop here, thank you!
The other day my aunt paid me a visit. She was overjoyed. “I got the highest mark in the mid-term examination!” she said. Don't be surprised! My aunt is indeed a student; to be exact, a college student at the age of 45.
Last year, she put aside her private business and signed up for a one-year, full-time management course in a college. “This was the wisest decision I have ever made,” she said proudly like a teenage girl. To her, college is always a right place to pick up new ideas, and new ideas always make her feel young.
“Compared with the late 70s,” she says, “now college students have many doors.” My aunt cannot help but recall her first college experience in 1978 when college doors began to be re-opened after the Cultural Revolution. She was assigned to study engineering despite her desire to study Chinese literature, and a few years later, the government sent her to work in a TV factory.
I was shocked when she first told me how she (had) had no choice in her major and job. Look at us today! So many doors are open to us! I believe there have never been such abundant opportunities for self-development as we have today. And my aunt told me that we should reach our goals by grasping all these opportunities.
Doing exercise
Having fun
When having to make a choice most people think they have to choose between the two. Far too often people go for the latter and naturally choose fun. For instance many people would prefer watching television, or more commonly known as TV to exercising, we all know that it’s true, right? The problem is, if you don’t exercise you will become weak and ultimately out of shape and it is no fun to be out of shape, right? So the question is, why not turn exercise into fun?
As an example, if TV is your favorite thing to do, why not connect your TV set to an electric generator that is charged by a stationary bike, you know, the kind of bike you peddle, that doesn’t go anywhere. So think about it, the more you watch TV, the fitter you’ll be.
Now if you are the kind of person who thinks listening to music is fun and you spend many hours alone tap tap tapping your fingers and your toes to the beat, why not take it one step further and get up on your feet and dance, dance, dance.
Or maybe you’re the type of person who prefers being with your friends. There are many ways one could have fun with their pals. For instance you could just hang out and do nothing or better yet you could get into a friendly game of basketball or football there is no rule that says everyone has to be as good as Yao Ming or David Beckham, right?
However sometimes there just aren’t enough players, or you may even be alone in which case you could go for a ride on your bike, maybe, stop by the library to borrow a book, or go for a walk around the park and enjoy the sunshine and scenery. Before you know it, you’re having fun.
Let’s face it, exercise is work and when we think of work we think of thankless underpaid hardships yet it needn’t be this way, if we think of exercise as fun.
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.
