节约用水英文演讲稿1Water is an important natural resource. The limited nature of water resources, the threats to their use (over-exploitation and pollution) and the imbalance in their distribution have now reached critical levels and will pose serious challenges to the international community in the coming years. More than one billion people worldwide source their drinking water from polluted founts, springs or rivers, reported the organization UNICEF on the UNs “Day of the Water” on March 22nd.Saving water at home, in the garden, or at work, takes very little effort, but makes a BIG difference. Dripping taps can waste up to 4 litres of water a day. Replace worn tap washers for a quick and cheap way of saving water. Use the minimum amount of water required when you boil water in saucepans and kettles; that way, you’ll save energy as well as water.Lets make contribution to the environment and save water as you can.节约用水英文演讲稿2Water is very important in our life.We drink it every day and use it to cook and wash things.We can not live without water.But how can we save water?There are several ways to save water.Firstly,take shorter showers and don’t leave the tap running when we don’t need to use water.Secondly,Try to reuse water .It’s the most importantway for us to save water.At last,We should not pollute water so that we willl have fresh water for years and years.If we do not save water,the last drop of water will be a teardrop.To protect water is to protect our life..Some people think theres much water on the earth.In fact,there is only a little water for us to use now.If we dont save it,it will surely be used out some day.Then what should we do?First,when we finish washing the clothes,we can use the water to clean the floor.Second,if we see the dripping tap,we ought to fix the tap as soon as possible.Third,we can have a shower instead of a bath because having a bath can waste a lot of water.In these ways,we can save not only huge amounts of water but also ourselves节约用水英文演讲稿3We are paying more attention on many environmental problems we made before, one of them is the water emergence. Long time ago, we never noticed that we are in a situation that the water on the earth is less than before, and the consequence is continuing. Until recently, we have started to acknowledge that we should make the bigger efforts to save water. Therefore, so save water from every single person is important. That is why we should save water at home. If every one of us saves water at home, then the water saved together would bea huge amout. And I have some suggestions following: we could cycle the water we just used them to wash clothes to water the plants or to rush the toilet; when we wash our hands, we could turn the tap off for the moment we put soap on our hands etc. So if we want to save water sincerely, we could save it at home .节约用水英文演讲稿4With the growing of the populaiton and the polution of rivers and lakes, it is now becoming more and more difficult for us to have access to drinking water. The shortage of drinking water has becoming a serious problem in many parts of our country. As a student, we should save water in our everyday life so as to reduce the effect of the drinking water shortage. Saving water should be the responsibility of every student.As a student, what can we do in our daily life to save water?First, we should realize the problem of drinking water shortage. Most of the times we waste water because we do not realize the problem. Once we have realized the problem we will do all that we can to save water in our life.Second, we can buy things that are water saving such as washing machines which are water saving. In this way , we can use less water doing the same thing than before thus saving a lot of water.Third, we can make use of waste water. Often, waste water are not fully used before they are poured off. We can reuse the water in many ways. For example, the water left after washing vegetables can be used to drop plants or to clean the floor.In a word, saving water is very important and we should do as much as we can to save water in our everyday life.节约用水英文演讲稿5As we all know, the earth is a planet almost covered by water，and it is water made every thing on the earth lively.water is also one of the important part of our environment.though，is there really so much water for us to clean，to produce many things，to play with? how much water are there on the earth then?most of the water is in the oceans or locked away as ice.thelargest volumes of fresh water are stored underground as groundwater，imagine there is only one barrel of water in the world，then there is only a spoon of it on the land，and the water we can use is only a drop of it.now i have to remind all of you here that the single drop of water is never as clean as before，it has been polluted severely by our human beings.There is a very beautiful river in paris.it is the seine，it runs across the city，people drink coffee, chat on the bank in the day，at night，they enjoy the beautiful scenery in the boat，songs from the river fly into the sky made the river more attractive, the seine is a famous symbol of france;on the west coast of pacific ocean there lies the modern city shanghai，another river which used to be a very important transportation route runs through the center of the city，people respected and regard it as"mother".it is the"suzhou river，but l believe that few of you would sit beside it，people will be scattered by the terrible smell of water when walk by.i have to say it is extremely dirty! and we all know that a lot of beautiful rivers in the world also are sharing the same fate with suzhou river. who is the devil? i cant help asking.Many human activities and their by-products have the potential to pollute water. please have a look along the banks of the river, large and small industrial enterprises discharge dirty.Water, tons of garbage were thrown into the river, the water contained so much that it cant clean itself. compared with the dramatic development in many sides of shanghai, the suzhou river has become a black point of the appearance of city.Fortunately, the government has control the situation now, we are happy to see some parts of the river has become clean again, and we even can find fish sometime.The unique earth is the only planet full of lives, the water is just like the blood in the active body, protecting water is saving ourselves. not to waste a single drop of water, otherwise, the only drop of water we could keep in the future would be our tear!My dear friends, mankind still faces a great difficulty in solving the problems of the environment and development, and there is a grand task to perform and along way to go. the middle school students in china will always cooperate with the young people of the world to protect the environment.。

ted演讲the mysterious of underwater -回复
ted演讲the mysterious of underwater -回复The Mysterious Underwater World: Unveiling the Secrets of the DeepIntroduction:Underwater exploration has always captivated the curiosity of humankind. The underwater world is a realm of breathtaking beauty and secrets that have yet to be fully uncovered. In this article, we will delve into the mysteries of the underwater world, exploring its vastness, the diverse life forms that exist within it, and the ongoing efforts to unravel its enigmatic nature.1. The Vastness of the Underwater World:The oceans cover approximately 71 of the Earth's surface, making them the largest and least explored ecosystems on our planet. However, our knowledge of these vast areas remains limited due to their inaccessibility and the challenges they pose to human exploration. The underwater world extends to unfathomable depths, with the deepest point of the Mariana Trench reaching over 36,000 feet below sea level. This vastness provides ample opportunities for research and discovery.2. Biodiversity in Underwater Ecosystems:Underwater ecosystems are home to an incredible array of biodiversity, sometimes surpassing that of their terrestrial counterparts. Coral reefs, for instance, are known as the rainforests of the sea due to their high levels of marine life. They provide habitats for numerous species, including fish, crustaceans, and corals themselves. These creatures exhibit remarkable adaptations to their environment, such as the bioluminescence seen indeep-sea organisms. Despite these remarkable discoveries, scientists estimate that we have only discovered a fraction of the species that inhabit the depths of our oceans.3. Unidentified Creatures:One of the greatest mysteries of the underwater world revolves around unidentified creatures that wander the depths. Over the years, numerous reports and myths have surfaced about supposed sea monsters or cryptids. These enigmatic beings capture the imagination and intrigue of many, leading to ongoing investigations to ascertain their existence. Examples include the Loch Ness Monster and the Kraken, which continue to fascinate and mystify both scientists and enthusiasts alike.4. Underwater Archaeology:Exploring the underwater world not only reveals natural wonders but also offers insights into our past through underwater archaeology. Submerged ancient cities, shipwrecks, and artifacts are hidden beneath the depths, waiting to be unearthed. These archaeological treasures provide invaluable information about past civilizations and a glimpse into the lives of those who came before us. From the sunken city of Atlantis, a fabled lost city, to the discovery of the Titanic wreckage, underwater archaeology sheds light on historical events and enhances our understanding of human culture.5. Challenges and Technological Advances:The exploration of the underwater world is not without its challenges. The extreme pressure and darkness pose significant hurdles for humans to venture into these depths. However, advancements in technology have revolutionized our ability to penetrate and study this mysterious realm. Remotely Operated Vehicles (ROVs) equipped with cameras and sensors have allowed scientists to explore deep-sea environments, gathering valuable data and imagery. Additionally, human-occupied submersibles have been developed to withstand the immense pressure, enablingus to dive to depths previously thought to be inaccessible. These technological strides have opened up new possibilities for exploration and discovery.Conclusion:The underwater world remains a captivating frontier, offering a wealth of mystery and exploration opportunities. From the vastness of the oceans to the remarkable biodiversity and unidentified creatures, each dive into the depths brings us closer to understanding this mystical realm. With continued advancements in technology and research efforts, the secrets of the underwater world may one day be fully unveiled, unraveling its many enigmas and further enriching our understanding of the world we inhabit.。
海洋奇观：Ted英语演讲稿UnderwaterAstonishment让你大开眼界
海洋奇观：Ted英语演讲稿UnderwaterAstonishment让你大开眼界Underwater Astonishment: Exploring the Wonders of the OceanGood afternoon, ladies and gentlemen. Today, I am delighted to share with you something truly remarkable: the amazing wonders of the ocean. As you might already know, over 70% of our planet’s surface is covered by water. However, most people only see the ocean from the surface, and never get to experience the variety of life found beneath it.That’s why I want to take you on a journey to discover the underwater world and the incredible creatures thatinhabit it.First of all, let's talk about the colorful and mesmerizing coral reefs. Coral reefs are home to thousands of different species of fish, as well as other sea creatures. Did you know that around 25% of all marine life depends on coral reefs for their survival? The Great Barrier Reef in Australia, for instance, is one of the largest and most diverse coral reef ecosystems in the world. It is home tomore than 1,500 species of fish, 600 species of coral, and numerous other marine animals. However, with climate change and ocean acidification, these beautiful and important ecosystems are at risk.Another fascinating undersea creature is the giant octopus, which is known for its intelligence and ability to camouflage itself. Octopuses are intelligent creatures, capable of solving complex problems, identifying patterns, and even opening jars. They also have the remarkable ability to propel themselves underwater by shooting water out of their mantle cavity.Moving on to the largest animal that inhabits the ocean, we have the blue whale. Blue whales are truly astonishing creatures, growing up to 30 meters long and weighing as much as 200 tons. This incredible mammal feeds on tiny krill, filtering huge amounts of water through its baleen plates. It’s hard to imagine a creature so large feeding on something so small.However, the ocean’s mysteries do not end with the creatures that inhabit it. There are also various geological features that are worth exploring beneath the surface. Forexample, the Marianas Trench is the deepest part of the ocean, reaching depths of almost 11 kilometers. The average depth of the ocean floor is around 3,800 meters, and yet we have only explored a small fraction of it.The ocean represents so much more than just an endless expanse of water. It is a realm of millions of fascinating species, diverse habitats, and magnificent geological features. It’s no wonder that the ocean has always captured the imagination of explorers, scientists, and artists alike.In conclusion, our planet’s oceans are incrediblydiverse and provide a habitat for millions of species of underwater life. Whether you’re interested in colorful coral reefs, intelligent octopuses, or massive blue whales, thereis s omething for everyone to discover beneath the ocean’s surface. So, the next time you’re by the coast, take sometime to explore the underwater world and uncover its mysteries. Thank you.。
hold breath underwater ted演讲
Hold Breath Underwater TED演讲引言大家好，我很荣幸能够在今天和大家分享一个我认为非常有趣和具有挑战性的主题——在水下屏息。
在这个快节奏的现代社会中，人们往往将自己局限在陆地上，而很少去探索水下世界。
然而，通过屏息潜水，我们可以以一种独特的方式与海洋相连。
在今天的演讲中，我将向大家介绍屏息潜水的好处、技巧和注意事项。
好处1. 探索未知领域屏息潜水可以让我们进入一个完全不同的世界，充满了许多美丽和神秘的事物。
在水下，我们可以发现各种颜色鲜艳的珊瑚礁、各种奇特的海洋生物以及令人惊叹的海底地貌。
这种冒险的感觉可以让我们感到无比兴奋和充实。
2. 改善健康和体能屏息潜水是一项需求体能和耐力的活动。
当我们屏息潜水时，我们的心率会下降，呼吸变慢，这有助于放松身心。
此外，由于在水下活动需要耐力和柔韧性，这也对我们的身体健康和体能有很大的好处。
屏息潜水还可以提高肺活量、增强心肺功能和锻炼水下呼吸的协调性。
3. 内心平静和意识提高屏息潜水需要我们将焦点放在呼吸和内心平静上。
当我们潜入水中时，我们必须放慢呼吸并保持冷静。
这种专注于呼吸的练习可以让我们感到更加深度的内心平静，并有助于提高我们的意识和专注力。
技巧1. 学习正确的呼吸方法屏息潜水的核心是控制呼吸。
我们需要学习正确的呼吸方法，以便在水下能够尽可能地延长呼吸时间。
一种常见的方法是深呼吸然后慢慢呼气。
在呼气时，我们应该放松身体并尽量延长呼气的时间。
2. 提高耐力和柔韧性要进行屏息潜水，我们需要有足够的耐力和柔韧性。
通过定期的锻炼和训练，我们可以提高我们的耐力和柔韧性。
例如，可以进行有氧运动、静态和动态伸展以及深度潜水练习来帮助我们提升在水下的表现。
3. 学习适应水下环境的技巧在水下环境中，我们会面临许多挑战，例如压力变化、浮力控制等。
因此，我们需要学习适应水下环境的技巧。
例如，我们可以通过稍微启动我们的耳朵来适应压力变化，并通过控制我们的呼吸和姿势来控制浮力。
奇妙海洋：Ted英语演讲稿UnderwaterAstonishment中海洋科学探秘
奇妙海洋：Ted英语演讲稿UnderwaterAstonishment中海洋科学探秘Ladies and gentlemen, good afternoon.It's my great honor to be here today to talk about the amazing world underneath the sea: the ocean. As we all know, the ocean covers over 70% of the Earth's surface and contains more than 95% of the world's living species. However, people still know very little about what is under the surface of the ocean and how the ocean affects our daily life. Therefore, in my speech today, I will introduce some of the mostfascinating discoveries and achievements in the field of ocean exploration in recent years.Firstly, let's talk about the ocean floor. According to the latest research, the ocean floor is much more complex and vibrant than we have ever imagined. For instance, it is home to a rich diversity of microorganisms, many of which arestill unknown to us, but have been found to play an important role in shaping the ocean's ecosystem. Moreover, the ocean floor is not a flat and barren landscape, but a mountainous and rocky terrain full of exotic creatures like giant tubeworms, deep-sea crabs, and even shrimp that can see infrared light.Secondly, the ocean is considered to be the largest carbon sink on Earth, absorbing over 25% of the carbon dioxide emitted by human activities. However, with the increase of carbon dioxide in the atmosphere, the ocean's pH value has been decreasing, which is known as ocean acidification. This process has severe consequences for the ocean's ecosystem, as it can harm or even kill many marine organisms and disrupt the entire food web. Therefore, scientists are working hard to find solutions to prevent or reduce ocean acidification, including developing new technologies to capture carbon dioxide from the atmosphere and injecting it into the ocean floor.Thirdly, the ocean also plays a crucial role in regulating our climate. For example, the Gulf Stream, a warm current in the Atlantic Ocean, carries heat from the tropics to Europe and warms the continent. Without this current, the climate in Europe would be much colder and harsher. However, the Gulf Stream is also vulnerable to climate change. If the ocean temperature rises too much, it can cause the Greenlandice sheet to melt rapidly, which would disrupt the Gulf Stream and have a devastating impact on the global climate.Lastly, let me talk about one of the most exciting discoveries in the field of ocean exploration: hydrothermal vents. These vents are found on the ocean floor and emit hot water that reaches temperatures of up to 400掳C, along with many minerals and chemicals. What is even more astonishing is the fact that these vents harbor a unique and diverse ecosystem of living organisms, some of which have never been seen before. For example, giant tubeworms with a length of over 2 meters, or the "yeti crab" that has furry arms that bacteria grow on and helps the crab feed. These creatures have adapted to live in an environment that was previously thought to be inhospitable to life, and their presence has challenged our understanding of life itself.To conclude, I hope that my speech has given you an insight into the mysterious and wonderful world of the ocean. As technology advances and more resources are invested in ocean exploration, we are sure to discover more secrets and marvels in this vast and diverse ecosystem. It's our responsibility to protect and preserve the ocean for the sake of future generations, for the ocean not only provides uswith resources and energy but also gives us a sense of wonder and enchantment that can never be found elsewhere.Thank you for listening.。

(笑声)我知道我现在像是个实习期的地质学家，不过我就是喜欢。
你可以看到这些生物发出的光，有些是为了避免被吃掉。
有些又是为引诱食物上钩。
尽管如此，用艺术的角度来看，这些都如此神奇。
再来看看这里发生了些什么——这条鱼有着会发光，闪烁的眼睛。
有些颜色则可以催眠。
多么有趣的图案。
这是最后一个：也是我的最爱，像转轮一样的设计。

到今天为止，我们只探索了其中的极小部分，大约只占了所有海洋的3%。
到现在，我们已经发现了世界上最高的山峰，最深的峡谷，水下湖，水下瀑布，还有我们刚才看到的。
然而，恰是我们曾经以为根本不可能有生命的地方，我们发现了众多的生物，还有它们的密度和多样性，都超过了热带雨林。
这告诉我们我们实际上对自己的星球还不甚了解。
还有剩下的97%，那里要不就是一片荒芜，要不就是充满惊喜。

头足类动物，有头有角。
小时候我把他们当作是枪乌贼。
这是一条章鱼。
这是来自rogerhanlon博士，海洋生物实验室的成果。
这些头足类动物真令人着迷，它用它们的眼睛，它们那难以置信的眼睛来观察周围的环境，看光，看图案。
这有只章鱼正在穿过礁石。
找到一个位置，停下来，卷起，然后马上消失在背景之中。
这很难做到。

这就是鱿鱼。
当雄性鱿鱼搏斗时，如果它们想要显示出自己的侵略性，它们就变为白色了。
这有两条雄鱿鱼在搏斗。
它们用撞屁股的方式来搏斗，真是挺有意思的方法。
这里有一条雄性在左边，雌性在右边。
看，这条雄性能有办法利用颜色把自己分为两半，所以雌性只能看到它温顺，优雅的一边，雄性--(笑声)再来看一次。
让我们再看一次。
注意它的颜色：白色在右边，棕色在左边。
它后退一步，让其它的雄性无法靠近来到另外一边，并且马上转换颜色。
瞧!以前有人告诉我这个雄性特征不仅仅是在鱿鱼身上，不过我也不太确定。

这是一只巨型澳大利亚墨鱼。
看它，看它那双无精打采的眼睛。
不过它们能做很神奇的事。
我们马上就能看到它退入到礁石的夹缝中去，注意它的触角。
它就这样把触角拉进来，使自己看起来像海藻一样。
刹那就消失在背景中。
多神奇!这又是两只雄性在搏斗。
当然，这些头足类非常聪明，他们知道如何不会伤害到对方。
不过看下它们能够利用皮肤来变换图案。
