第一篇：初中三分鐘演講稿
尊敬的老師、親愛的同學(xué)們：
大家好！今天我演講的題目是“勇氣”
何謂勇氣？勇氣就是在合適的時間，用自己的膽識把一件事情辦對、辦好。所以“勇氣”不但要有“勇”，還要有“氣”?！坝隆毕笳髦茏龀鲞@件事的膽識，“氣”象征著把這件事辦對辦好的能力。有“勇”無“氣”，終歸是一介莽夫，成不了大事;有“氣“無”勇“，只能籍籍無名，成了有“勇”又有“氣”之人的墊腳石。
那什么才是有“勇”又有“氣”的人呢？
漢武帝劉徹，十六歲登基，執(zhí)掌大漢江山五十四年，成就了漢朝的鼎盛。他有“勇“。分布“推恩令”，敢于向父兄一輩的諸侯王們挑戰(zhàn);亦有“氣”，廣納賢才，改革貨幣、北拒匈奴，成為了中國歷史上的明君之一。
我國“兩彈一星”元勛錢學(xué)森，為中國軍事發(fā)展立下赫赫戰(zhàn)功。他有“勇”， 在新中國成立之時放棄美國的高官厚祿，只身來到百廢待興的新中國;亦有“氣”，不但為人高風(fēng)亮節(jié)，而在發(fā)射場事必躬親，最終成就了新中國在這一領(lǐng)域達(dá)到世界領(lǐng)先的水平。
也許同學(xué)們可能會問了：以上兩位都是震古爍今的偉人，我們怎么會成為這樣的人？我的回答是：不！或許我們做不成這些大事，但“勇氣”的磨煉定然要從小事開始。對老師提出一個對班級有益的意義，為被難題困擾的同學(xué)解答問題，在樓道的門口用掃把把積雪掃到一邊，它們都包含了“膽識”和“能力”兩個方面。如果在平常的小事中不斷歷練自己的勇氣，等到你遇到 了做大事的機(jī)遇，那些你積累的小勇氣就會厚積薄發(fā)，變?yōu)榇笫碌某晒?。到時候，或許名垂青史就不再是個夢想！
那么就讓我們行動起來吧！用自己的能力，證明自己是個有膽識、有能力的人―當(dāng)然，從小勇氣轉(zhuǎn)化為大勇氣是一個蛻變的過程。希望幾十年后，今天的我們，也會變成一群有勇氣的人！
我的演講到此結(jié)束，謝謝大家！

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 ”

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.
