有关全球气候变暖的英语演讲稿
Global WarmingThere is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). The warmest since the mid 1800’s was the 1990s. The hottest years recorded were 1997, 1998, 2001, 2002, 2003. The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.So now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?The answer is simpler than you may think. You don’t have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help us all.Firstly, plant a tree. This could be easier than it sounds. Join or help out a local wildlife group and ask to plant a tree. Trees, when fully grown, will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?When you are at home, and your getting a little cold. Put a jumper on and do not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.If possible, buy your fruit and vegetables from local suppliers. And try to avoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use, making the pollution higher. Also, SUV’s make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.If possible use solar energy, after all it is free; all you need to buy is the equipment. You can get much of your hot water and heating from the sun and even generate electricity. Reduce, reuse and recycle. Only buy what you need; don’t stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, and try to do your part. After all, it will be our next generation that will feel the effects.
全球变暖演讲稿 800字左右
全球变暖可能造成的影响 全球变暖将给地球和人类带来复杂的潜在的影响，既有正面的，也有负面 的。
例如随着温度的升高，副极地地区也许将更适合人类居住；在适当的条件下， 较高的二氧化碳浓度能够促进光合作用，从而使植物具有更高的固碳速率，导致 植物生长的增加，即二氧化碳的增产效应，这是全球变暖的正面影响。
但是与正 面影响相比，全球变暖对人类活动的负面影响将更为巨大和深远。
今年8月份CCTV报道，由于气候变暖的影响，珠穆朗玛峰的顶峰下降了1.3米。
祁连山冰川缩减危及河西走廊：近年来，祁连山冰川融化比上个世纪70年代减少了大约10亿立方米，冰川局部地区的雪线正以年均2-2.6米的速度上升。
专家分析，冰川退缩，雪线上升除自然气候因素外，另一个主要原因是人口膨胀，超载超牧，过度开垦，乱砍滥伐，滥采地下水有关。
《中国环境报》2004-9-16 1、海平面上升的影响 过去的百年海平面上升了14．4cm,我国上升了11．5cm。
海平面升高的原因，主要是海水热膨胀，当海洋变暖时，海平面则升高。
全球升温会引起地球南北两极的冰山融化，这也是造成海平面上升的主要原因之一。
海平面上升的直接影响有以下几个方面： (1) 低地被淹： 英国加高堤坝应对气候变暖 全球变暖使海平面升高，暴风雨频率增加，这使英国人不得政治面目 加高防洪堤坝。
据英国官方近日公布的统计数据，在过去的20年中，由于泰晤士河的水位随全球变暖而升高，当地政府机构不得不先后88次加高防洪堤坝，以保障伦敦人的生命财产安全。
，据悉，人们现在平均每年4次加高其堤坝。
据估计，在2030年以前，其加高堤坝的频率会达到每年30次。
钟和 中国环境报2004-10-19 (2) 海岸被冲蚀 (3) 地表水和地下水盐分增加，影响城市供水。
（4）地下水位升高。
(5) 旅游业受到危害(海平面上升50米,大连、秦皇岛、青岛、北海、三亚滨海旅游区向后31-366料，沙滩损失24%，北戴河沙滩损失60%。
2002年中国国土资源公报报道，沿海旅游业已成为第一大产业，其产值为2503亿元，占海洋产业总产值的34.6%。
（6） 影响沿海和岛国居民的生活(占世界1／3的人口)，使之受到威胁。
如果极地冰冠融化，经济发达、人口稠密的沿海地区会被海水吞没，马尔代夫、塞舌尔等低洼岛国将从地面上消失，上海、威尼斯、香港、里约热内卢、东京、曼谷、纽约等海滨大城市以及孟加拉、荷兰、埃及等国也将难逃厄运。
2、对动植物的影响 气候是决定生物群落分布的主要因素，气候变化能改变一个地区不同物种的适应性并能改变生态系统内部不同种群的竟争力。
自然界的动植物，尤其是植物群落，可能因无法适应全球变暖的速度而做适应性转移，从而惨遭厄运。
以往的气候变化(如冰期)曾使许多物种消失，未来的气候将使一些地区的某些物种消 失，而人些物种则从气候变暖中得到益处，它们的栖息地可能增加，竞争对手和 天敌也可能减少。
比如说桔子，过去20世纪70年代，它的最北的边界线是在黄 山一线，宣城市也曾经试种过，但到冬天的一场大雪，树木就冻死了。
但现在我 们校园里的桔子树都长得很好。
又如，扬子鳄只生活在宣城、泾县和南陵这样狭 小的地带，如果北界线北移，扬子鳄可能会自然绝种。
这是从我省的局部地区来 讲。
从全国来讲，我国把冬季1月0度等温线作为副热带北界，目前这一界线处 于我国秦岭-淮河一带。
研究发现，气温升高会使这一界线北移至黄河以北，徐 州、郑州一带冬季气温将与现在的杭州、武汉相似。
3、对农业的影响 一年中温度和降水的分布是决定种植何种作物的主要因素，温度及由温度引起降水的变化将影响到粮食作物的产量和作物的分布类型。
气候的变化曾经导致生物带和生物群落空间(纬度)分布的重大变化。
如公元800-1200年北大西洋地区的平均温度比现在高1℃，使玉米在挪威种植成为可能，但到了公元1500-1800年，西欧出现小冰川期，平均气温也只比现在低1-2℃，就造成了挪威一半农场弃耕，冰岛的农业耕种活动则几乎全部停止。
除此之外，全球变暖还会使高温、热浪、热带风暴、龙卷风等自然灾害加重。
因此，全球气温升高后，世界粮食生产的稳定性和分布状况将会有很大变化。
4、对人类健康的影响 人类健康取决于良好的生态环境，全球变暖将成为下个世纪人类健康的一个 主要因素。
极端高温将成为下世纪人类健康困扰变得更加频繁、更加普遍，主要 体现为发病率和死亡率增加，尤其是疟疾、淋巴腺丝虫病、血吸虫病、钩虫病、 霍乱、脑膜炎、黑热病、登革热等传染病将危及热带地区和国家，某些目前主要 发生在热带地区的疾病可能随着气候变暖向中纬度地区传播。

Today, economy is advancing at a fast pace and together with it, the climate. Greenhouse gases is getting more and more and the world ，with its rising temperature, is having a 'fever. Due to the icebergs melting rapidly, the sea level is increasing and who knows when it will drown some of the islands and wipe out civilizations ? Natural disasters are all taking place more often than not. So, is there no help at all? What can we do to slow down the pace of global-warming? First of all, we can use the clean energy which will not pollute the air , the ground or the sea. Some examples are the solar energy, the wind energy and the wave energy. Secondly, we can plant more trees . One way in which the tree can help is that it takes in carbon dioxide , a greenhouse gas, and releases oxygen instead. Isn't this killing two birds with one stone? Lastly, we can reduce the use of cars and walk instead. The cars let off exhaust gases and pollute the earth. If we use our legs instead, we can do our part on saving the earth and even exercise at the same time!

48.英语演讲稿：创新思维 Honorable teachers, ladies and gentlemen, and my fellow sutdents: Good morning! It’s my pleasure to stand here to make a speech. First of all , let me introduce myself. My name is TongYao. I am from Class 2 Grade 7 in ChengGong middle school ! Today , my topic is : “Innovative Thinking” Have you ever thought that what is Innovative Thinking ? Somebody will said ,“thinking something different !” In fact, it’s not so simple. Have you ever thought how to think something different ? Now , let me explain it to you in detail ! First , we should admit that Innovative ideas do start in one mind before taking on the world. Only in this way ,we have the power of Innovation . For example , the radio, television, telephone and so on, all were developed by scientists . And these scientists all had the ability and courage to think something different . It is a well know fact that Albert Einstein was the mastermind of the nuclear bombs . Second , we should be good at discovering , and be able to break the conventions. Sometimes, there are a lot of subjects of Innovation around us . But more often we lack the ability of discovering So, only if we be good at discovering and summing up ,we can innovate . Finally, I want to say , as a middle school student in the new century, we must have the courage and confidence to make innovations.)And we should study hard for development of our country ! Because we are the builders of our motherland !Honorable teachers, ladies and gentlemen, and my fellow sutdents， according to what I have said above , have you learnt more about the “Innovative Thinking” ? Of course ,you have ! I believe my speech is perfect ! And I also believe that as long as we expand our thinking , we will find something different . That’ s all ! Thank you for your listening!尊敬的老师，先生们女士们，以及我的各位同学们：大家早上好!很高兴我能站在这里为大家演讲.首先，请允许我进行一下自我介绍，我的名字叫童尧。
我来自成功中学的七年级2班! 今天，我演讲的题目是：创新思维)。
请问你们曾经想过什么是创新思维吗?也许有人会直接说，“就是想一些不一样的东西!”事实上没这么简单。
那么你有没有想过如何去想一些不一样的东西呢?那么现在，就让我为你仔细的解释一下吧! 首先，我们应该承认：创新思维的确是先在人的思想中产生，然后再发生在这个世界中。
只有这样，我们才有创新的动力。
举个例子，收音机、电视机、电话等都是由科学家发明的并且，这些科学家都有能力和勇气去想一些不一样的东西。
譬如说众所周知的爱因斯坦就是原子弹的发明人。
其次，我们应该善于发现，并且能够打破常规。
有时候，我们身边就有很多创新的素材，但更多的时候我们却缺乏发现的能力。
所以，只有我们善于发现，善于总结，我们才会发明创新。
最后，我想说，作为新世纪的中学生，我们应该有勇气和信心去开拓创新!(并且，我们应该为了我们祖国的发展而努力学习!因为，我们是祖国的建设者尊敬的老师，先生们女士们，以及我的同学们, 通过我以上的陈述你们对创新思维有了更多了解了吗? (当然，我认为这是肯定的! 因为我相信我的演讲是很成功的并且我相信只要我们拓展我们的思想，我们就能发现一些不一样的事物。
我的演讲完毕，谢谢你们的聆听!49.英语演讲稿：health健康We care about ourselves more and more. We eat what's right and we exercise. We absolutely embrace health. However, it is not only our health that we should embrace, though many of us do not realize that. Many of us do not realize that the earth we live on is a fragile being that needs to be protected like a new born child. We probably haven't even noticed, that with each stride the civilization takes toward the ultimate development, more burdens are added to the earth that provides us with essentials to live. The decrease in air quality, the climate change, medical waste, noise and water pollution, and even food poisoning has added to the list of growing concerns to our living environment. Human are not supernatural beings, thus these problems have affected pretty much every matter. We upgrade gadgets and make full use of newer technologies, but we pay for the consequences in turn. For instance, the advent of batteries and machinery has caused million tons of water become toxic and undrinkable, further aggravating the already serious condition of water shortage and poisoning in several countries. The over-production and over-use of transportation vehicles and electricity has contributed to the Global Warming and caused myriads of species to disappear from the face of the earth due to home-loss and temperature change. We have brought wonders to the world, but have also destroyed miracles of nature. We are concerned about our nutritional intake and exercise all the time, so why shouldn't we care about the conditions of our living planet as well? Time is ticking on. We shouldn't put off the whole save the environment affair any longer. Please, do what feels right in our hearts, even though it is only a tiny matter. Save up resources, promote the recycling and reusing of products, and always remember to take some time off going into the woods and breathe in the sweetness in the air. We have come from the woods, thus we would all have a secret desire in our hearts to harmonize with nature again. Remember, every little thing matters. 我们关心自己越来越多。
我们吃什么的权利和我们的工作。
我们绝对拥抱健康。
然而，它不仅是我们的健康，我们应该接受，但我们中许多人没有意识到这一点。
我们中的许多人没有意识到，我们生活在地球上是一个脆弱的，需要加以保护，就像一个新出生的孩子。
我们可能还没有注意到，这与每个大步走向文明需要的最终发展，更多的负担增加的地球为我们提供了必备的生活。
减少了空气质量，气候变化，医疗废物，噪音和水污染，甚至增加了食物中毒的名单越来越关注我们的生活环境。
人权不是神仙，从而造成这些问题的影响非常每此事。
我们升级产品，并充分利用新技术，但我们付出的后果反过来。
举例来说，电池的到来和机械已造成万吨的水变成有毒和报废，这进一步加剧本已严重的水资源短缺和中毒的几个国家。
过度生产和过度使用的运输车辆和电力促成了全球变暖，并造成无数物种消失从地球的表面上，由于房屋损失和温度变化。
我们带来了奇妙的世界，而且还摧毁了大自然的奇迹。
我们关心的是我们的营养摄入量和锻炼的时间，为什么不应该我们关心我们的生活条件的星球呢? 时间在流逝的。
我们不应该推迟整个“保存环境”的事了。
请给我什么感觉权在我们的心中，尽管它只是一个小问题。
节省资源，促进了回收和重复使用的产品，并永远记住采取一些休息时间进入伍兹和呼吸在空气中的甜味。
我们有来自树林，因此，我们都将有一个秘密的愿望在我们的心中，协调人与自然的。
请记住，每一个小东西事项。

我急需一篇关于绿色生活，低碳生活的英语演讲稿，要在一分钟以内讲完。
我不清楚你的个人状况，无法写自我介绍…… With the development of modern industry, there is a growing concern about environment pollution. Faced with problems such as global warming and acid rain, it is high time that some effective measures should be taken. And the first thing we can do, would be living a low carbon life. Low carbon life is not so difficult as it heard to be. It is among our daily life. For example, do not drive your own car when you can just take a bus. Do not write a card, when you can just send an e-mail to say “happy birthday”. And do not buy something when you can just make one with old things. Living a low carbon life is easy, healthy, and of course environmentally friendly. Therefore, low carbon life is a tendency of our society. Moreover, if all of us live a low carbon life, the green house effects would be ceased in the future. As long as all of us live a low carbon life, the 2012 would never come. 随着现代工业的发展，环境污染受到越来越多的关注。
面对诸如全球变暖、酸雨等问题，是时候应该采取适当、有效的措施了.而第一件要做的事就是过低碳生活。
低碳生活并不是像我们想象的那样复杂，它存在于我们的日常生活之中。
例如我们不坐私车改坐巴士。
当你可以通过E-mail祝贺生日时就不写卡片。
当你可以改造旧东西就不买新的东西。
低碳生活是简单的、健康的，当然也是有助于环境的。
因此，低碳生活是社会的潮流。
而且，如果我们都过低碳生活，未来就不会有温室效应。
只要我们都过低碳生活，2012就永远不会到来
