环境（Environment） Like all other living beings, humans have clearly changed their environment, but they have done so generally on a grander scale than have other species. Some of these changes-such as the destruction of the world's tropical rain forests to create grazing land for cattle or the drying up of almost three-quarters of the Aral Sea, once the world's fourth-largest freshwater lake, for irrigation purposes-have led to altered climate patterns, which in turn have changed the distribution of species of animals and plants. Scientists are working to understand the long-term consequences that human actions have on ecosystems, while environmentalists-professionals in various fields, as well as concerned citizens in the United States and other countries-are struggling to lessen the impact of human activity on the natural world. Population Growth（人口增长） Human population growth may be seen to be at the root of virtually all of the world's environmental problems. Increasingly large numbers of people are being added to the world every year. As the number of people increases, more pollution is generated, more habitats are destroyed, and more natural resources are used up. Even if new technological advances were able to cut in half the environmental impact that each person had, as soon as the world's population size doubled, the earth would be no better off than before. The Population Division of the United Nations predicts that the 5.63 billion humans alive in 1994 will increase to 6.23 billion in the year 2000, 8.47 billion in 2025, and 10.02 billion in 2050. The UN's estimate assumes that population will peak and stabilize at 11.6 billion in 2200. Although it is true that rates of population increase are now much slower in the developed world than in the developing world, it would be a mistake to assume that the population growth problem is primarily a problem of developing countries. In fact, because larger amounts of resources per person are used in the developed nations, each citizen from the developed world has a much greater environmental impact than does a citizen from a developing country. Evidence now exists suggesting that the most important factors necessary to lower population growth rates in the developing world are democracy and social justice. Studies show that population growth rates have fallen in areas where several social conditions have been met. In these areas, literacy rates have increased, and women are given economic status equal to that of men and thus are able to hold jobs and own property; also, birth control information is more widely available, and women are free to make their own reproductive decisions. Global Warming（全球变暖） Like the glass panes in a greenhouse, certain gases in the earth's atmosphere permit the sun's radiation to heat the earth but retard the escape into space of the infrared energy radiated back out by the earth. This process is referred to as the greenhouse effect. These gases, primarily carbon dioxide, methane, nitrous oxide, and water vapor, insulate the earth's surface, helping to maintain warm temperatures. If the concentration of these gases were higher, more heat would be trapped within the atmosphere, and worldwide temperatures would rise. Within the last century, the amount of carbon dioxide in the atmosphere has increased dramatically, largely because of the practice of burning fossil fuels-coal and petroleum and its derivatives. Atmospheric scientists have now concluded that at least half of that increase can be attributed to human activity, and they have predicted that unless dramatic action is taken, temperature will continue to rise by between 1° and 3.5° C over the next century. The consequences of such a modest increase in temperature may well be devastating. Sea levels will rise, completely inundating a number of low-lying island nations and flooding many coastal cities such as New York and Miami. Many plant and animal species will probably be driven into extinction, agricultural regions will be disrupted, and the frequency of severe hurricanes and droughts is likely to increase. Depletion of the ozone layer（臭氧层变薄） The ozone layer, a thin band in the stratosphere （a layer in the upper atmosphere）, serves to shield the earth from the sun's harmful ultraviolet rays. In the 1970s, scientists discovered that the layer was being attacked by chlorofluorocarbons （CFCs）, chemicals used in refrigeration, air-conditioning systems, cleaning solvents, and aerosol sprays. The consequences of the depletion of the ozone layer are dramatic. Increased ultraviolet radiation will lead to a growing number of skin cancers and cataracts and also reduce the ability of people's immune systems to respond to infection. Additionally, the growth rates of the world's oceanic plankton, the base of most marine food chains, will be negatively affected, perhaps leading to increased atmospheric carbon dioxide and thus to global warming. Predicting the rate of ozone depletion is difficult. Optimists claim that if international agreements for the phasing out of ozone-depleting chemicals agreed to in Montréal in 1987 are followed, ozone loss will peak in the year 2000. With many of the world's fastest growing countries in the process of industrializing and modernizing, there is reason to believe that destruction will continue to increase well beyond that year. Air pollution（空气污染） A significant portion of industry and transportation is based on the burning of fossil fuels, such as gasoline. As these fuels are burned, chemicals and particulate matter are released into the atmosphere. These chemicals interact with one another and with ultraviolet radiation in sunlight in various dangerous ways. Smog, usually found in urban areas with large numbers of automobiles, can cause serious health problems. Acid rain is a serious global problem because few species are capable of surviving in the face of such acidic conditions. Acid rain has made numerous lakes so acidic that they no longer support fish populations. Acid rain is also thought to be responsible for the decline of many forest ecosystems worldwide. Water pollution（水污染） Estimates suggest that nearly 1.5 billion people lack safe drinking water and that at least 5 million deaths per year can be attributed to waterborne diseases. Water pollution may come from point or nonpoint sources. Point sources discharge pollutants at specific locations-from, for example, factories, sewage treatment plants, or oil tankers. The technology exists for point sources of pollution to be monitored and regulated, although political factors may complicate matters. Nonpoint sources-runoff water containing pesticides and fertilizers from acres of agricultural land, for example-are much more difficult to control. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes. With almost 80 percent of the planet covered by oceans, people have long acted as if those bodies of water could serve as a limitless dumping ground for wastes. Raw sewage, garbage, and oil spills have begun to overwhelm the diluting capabilities of the oceans, and most coastal waters are now polluted. Beaches around the world are closed regularly, often because of high amounts of bacteria from sewage disposal, and marine wildlife is beginning to suffer. Groundwater pollution（地下水污染） Water that seeps through porous rocks and is stored beneath the ground is called groundwater. Although groundwater is a renewable resource, reserves are replenished relatively slowly. When groundwater is depleted in coastal regions, oceanic salt water commonly intrudes into freshwater supplies. Saltwater intrusion is threatening the drinking water of many areas along the Gulf and Atlantic coasts. The EPA has estimated that, on average, 25 percent of usable groundwater is contaminated, although in some areas as much as 75 percent is contaminated. Contamination arises from leaking underground storage tanks, poorly designed industrial waste ponds, and seepage from the deep-well injection of hazardous wastes into underground geologic formations. Because groundwater is recharged and flows so slowly, once polluted it will remain contaminated for extended periods. Habitat Destruction and Species Extinction（居住环境破坏与物种灭绝） It is difficult to estimate the rate at which humans are driving species extinct because scientists believe that only a small percentage of the earth's species have been described. What is clear is that species are dying out at an unprecedented rate; minimum estimates are at least 4000 species per year, although some scientists believe the number may be as high as 50,000 per year. The leading cause of extinction is habitat destruction, particularly of the world's richest ecosystems-tropical rain forests and coral reefs. At the current rate at which the world's rain forests are being cut down, they may completely disappear by the year 2030. If growing population size puts even more pressure on these habitats, they might well be destroyed sooner. This loss is critical from several perspectives. The economic value of species lost and of natural products and drugs that never will be discovered or produced is incalculable. Similarly, it is impossible to place either a moral or an aesthetic value on our growing list of extinct species. As habitats are destroyed and species lost, the world is increasingly losing threads from the interconnected fabric of life. Chemical Risks（化学成分污染） Pesticide residues on crops and mercury in fish are examples of toxic substances that may be encountered in daily life. Many industrially produced chemicals may cause cancer, birth defects, genetic mutations, or death. Although a growing list of chemicals has been found to pose serious health risks to humans, the vast majority of substances have never been fully tested. Environmental Racism（环境歧视） Studies have shown that not all individuals are equally exposed to pollution. Three of the five largest commercial hazardous waste landfills in America are in predominantly black or Hispanic neighborhoods, and three out of every five black and Hispanic Americans live in the vicinity of an uncontrolled toxic waste site. The fact that the wealth of a community is not nearly as good a predictor of hazardous-waste locations as is the ethnic background of the residents reinforces the conclusion that racism is involved in the selection of sites for hazardous-waste disposal. Environmental racism takes international forms as well. Dangerous chemicals banned in the United States often continue to be produced and shipped to developing countries. Additionally, the developed world has shipped large amounts of toxic waste to developing countries for less-than-safe disposal. Energy Production（能源问题） The world cannot continue to rely on the burning of fossil fuels for much of its industrial production and transportation. Fossil fuels are in limited supply; in addition, when burned they contribute to global warming, air pollution, and acid rain. Nuclear energy as an alternative is opposed by many because of the massive devastation an accident can cause. The accident at the Chernobyl' nuclear power plant in 1986 scattered radioactive contamination over a large part of Europe. Approximately 135,000 people were evacuated, and human health has been dramatically affected. The World Health Organization released a report in late 1995 attributing the "explosive increase" in childhood thyroid cancer in Belarus, Ukraine, and Russia directly to the accident. One reasonable solution is to combine conservation strategies with the increased use of solar energy. The price of solar energy relative to traditional fuels has been dropping steadily, and if environmental concerns were factored into the cost, solar power would already be significantly cheaper. Although it is desirable to have a wider range of energy options, other alternative sources of power （such as wind, geothermal, or hydroelectric） are not likely to provide large-scale solutions in the forseeable future. Conclusion Global environmental collapse is not inevitable. But the developed world must work with the developing world to ensure that new industrialized economies do not add to the world's environmental problems. Politicians must think of sustainable development rather than economic expansion

Good morning/afternoon!It is my great honor to be here to give you this simple speech about disabled people and their living condition. According to the survey, the number of disable people have kept increasing in all the countries around the world; it leads to a series of social problems. We should render more attention to this kind of group, otherwise, all those problems could be worsened.Disabled people are suffering from the difficulties we could never imagine. Think about it, what if you cannot see the road when you want to go out? What if you cannot hear the sound when you want to listen to the music? What if you just cannot reach the staff you urgently need and you just do not have the ability to do so? These are the most basic difficulty they are confronted in everyday life. Putting it aside, we even cannot understand or try the lives of their family. They cannot enjoy the normal life. They have to bring a wheel chair or even bigger equipment everywhere they go. A simple sentence should be spoken a lot of times or write on a piece of paper or make a guest to be understandable to their dearest family. Beside all above I mentioned, there are a group of people who give heartless discrimination to disabled people. They cannot enter into some restaurant, garden, public entertainment places where they should have the same right as us; not mention the prejudice given in the employment. It is unfair that we show discimination to people who need our special care. Therefore, as a qualified social member with high education, we need to render our love to the disabled people and their family, and make the people around us to be aware of this. Thank you very much!100%原创 内容应该比较适合简单的课堂演讲了

Courage -- John KennedyThe courage of life is a less dramatic spectacle than the courage of a final moment; but it is no less a magnificent mixture of triumph and tragedy. A man does what he must – in spite of personal consequences, in spite of obstacles and dangers and pressures – and that is the basic of all human morality. To be courageous … requires no exceptional qualifications, no magic formula, no special combination of time, place and circumstance. It is an opportunity that sooner or later is presented to us all. Politics merely furnishes one arena which imposes special tests of courage. In whatever arena of life one may meet the challenge of courage, whatever may be the sacrifices he faces if he follows his conscience – the loss of his friends, his fortune, his contentment, even the esteem of his fellow men – each man must decide for himself the course he will follow. The stories of past courage can define that ingredient – they can teach, they can offer hope, they can provide inspiration. But they cannot supply courage itself. For this each man must look into his own soul.勇气——约翰。肯尼迪人生之中的勇气，常常不像千钧一发时刻的要求那样充满戏剧性；但是它却同样是一个有关胜利与悲剧的壮观结合体。一个人要去做他必须做的任何事情——将个人得失置之度外，诸多的障碍、危险、和压力抛诸脑后——这便是人类一切道德的基础。勇敢。。。。。。不需要额外的条件，也没有奇妙的规则，同样也不需要时间、地点和情势的特异结合，我们每个人迟早都会遇到这样一个机会。政治只不过是对勇气进行特别考验的一个场所罢了。无论在人生的何种场合下遭遇勇气的挑战，也不论是为了遵从自己的良知而将面对的牺牲——朋友、财富和满足的丧失，甚至于其他人对你的尊重——每个人都必须自己决断其所遵行的方针路线。他人勇敢的故事可以阐述那个因素——能够教导我们，为我们提供希望和灵感，但却不能给予我们勇气。因此，每个人必须深入到自己的灵魂之中去寻找勇气。

原文：尊敬的各位领导、各位同事，亲爱的朋友： 大家好： 当吹面不寒杨柳风，碧波万里惹人醉的时候，当一切都沉浸在一种安详平和的气氛中的时候，一场声势浩大的“保持共产党员先进性教育”活动正在如火如荼地进行着。 在世界的东方，有着九百六十万平方公里的泱泱大国，这条腾飞的巨龙，活跃着许许多多可歌可泣、震撼人心的先进人物，他们默默无闻地在各自的工作岗位上，履行着光荣而神圣的职责，他们用并不比我们强健的身躯甚至鲜血和生命，以坚定的信念，始终站在时代的前列，团结带领人民群众，把中国特色社会主义事业不断推向前进。在每个年代，在每天，在每个工作岗位上，都有无数的诸如张思德、雷锋、焦裕禄、孔繁森、任长霞等等英雄儿女在演绎着伟大的奇迹，在高天之下、厚土之上奏唱着一曲曲英雄的凯歌。 在他们的眼中，恪尽职守的职业道德胜过高薪厚禄的金钱利欲，勤勤恳恳舍生忘死的工作激情是对党和人民托付的最好诠释，他们的魅力为我们筑起了一座不朽的丰碑，吸引了多少中华儿女，震撼了多少人的心灵，他们的心中都有一个信仰，那就是我们伟大的党！ 牛玉儒，这位人民的公仆，靠着对党的坚定信念、靠着对党的无限忠诚，谱写了一曲美的奉献之歌。他象一面鲜红的旗帜，是一座用钢铁铸成的丰碑，是中华民族的脊梁。这位把党的事业高于一切，把人民的利益高于一切，俯首甘为儒子牛的公仆，虽然离我们远去了，但他对事业的执著，勤政为民、鞠躬尽瘁的奉献精神，清正廉洁、一身正气的公仆精神，仍然令我们感动、引我们深思。他是党和人民的骄傲，永远是我们学习的好榜样。 从中，我们看到了一个个共产党员在党旗下的誓言；看到了一个个廉洁自律、一身正气、两袖清风的时代楷模。从他们的眼睛中，我们阅读到什么是忠诚；从他们的事迹中，我们读懂了英雄的本色。澎勃的朝气、昂扬的锐气、浩然的正气，在他们身上闪烁着光芒，我想这正是党的先进性的具体体现和根本所在。 讲到这儿我心情无比激动，很不平静，我，一个共产党员，一个残疾人工作者，我要以他们为学习的楷模，为残疾人的事业燃烧激情。 如今，“保持共产党员先进性”教育活动已逐步走向高潮，它是党对每个党员的关怀、爱护、激励和鞭策，也是党为了提高党员的政治素质，纯洁党的队伍，增强党的凝聚力和战斗力的一项强有力的举措。所以“保持共产党员先进性”教育是阳光加雨露，使每个党员能够茁壮成长，使我们的党能永远立于不败之地。 近年来，党和国家十分重视残疾人和残疾事业，胡锦涛曾经说：“残疾人有人的尊严和权利，有参与社会生活的愿望和能力。历史和现实表明，他们同样是社会财富的创造者。”如今，残疾人平等、参与、共享社会生活已得到充分体现。2005年的春节晚会上，《千手观音》一舞给我们带来了巨大震撼，难道这不是残疾人的风采吗？再次印证了“爱是我们共同的语言”。 然而，众所周知，由于生理和心理上的缺陷，残疾人的社会参与能力和竞争力都处于弱势，决定了他们是一个特殊困难的群体，无论在康复、教育、就业、婚姻家庭等方面都存在大量的问题和实际困难，因此迫切需要我们每个残疾人工作者的关心、支持和帮助，为他们提供真实的、具体的、有效的服务。如今，“全面实现小康”的号角已吹响，如何发展残疾人事业，带领身边的残疾人致富奔小康，已是我们每个残疾工作者义不容辞的责任。 我是一名共产党员，是一个残疾人工作者，也是一个好激动的人，对生活、事业充满了诸多热情和激情，正是这股激情始终澎湃在我的胸膛里，伴随着我行进在残疾人事业发展的历程中，走过春夏秋冬、走过酸甜苦辣、走向成长、走到今天。身为残疾人工作者，担负着代表、管理、服务残疾人的工作职责，十几年如一日，我严格要求自己，始终保持坚定正确的理想信念，始终牢记党的宗旨，始终保持开拓进娶求真务实的工作作风和精神状态，始终把实现和维护全体残疾人的根本利益作为自己义不容辞的责任，切实履行全心全意为残疾人服务的宗旨，从本职岗位做起，从平凡小事做起，脚踏实地践行“三个代表”要求，真正做到权为残疾人所用、情为残疾人所系、利为残疾人所谋，密切与残疾人的血肉联系，公正清廉、无私奉献，努力做一名党的好干部、残疾人的贴心人，，以实现党的先进性的标准。 在我演讲将要结束的时候，我想再说几句内心的话：残疾不是某个人的错，残疾是人类繁衍和社会发展过程中不可避免而又不得不付出的一种社会代价，就像一棵根深叶茂的大树，风吹过，雨打过，总会有残损受伤的树叶树枝，但我们同样是同根同枝的兄弟姐妹。 我，一个共产党员，残疾人的代表，心存残疾人苦，权为残疾人所用，我要以高度的责任感和使命感，为残疾人的美好明天奉献自己的光和热；我要以饱满的热情和不懈的努力在残疾人的事业上写就最美丽的诗篇，对党忠诚，维护党的利益，为党的事业奋斗终身！翻译后：Distinguished leaders, dear colleagues, dear friends: Good: Should puff no cold poplar and willow wind, bluish waves ten thousands li let people drunk moment, think that all immerse "the advanced Commumist party member sex education activity is in progress in course of flaring like fire set to dry tinder in moment in one kind of serene gentle atmosphere , one keeping" gigantic and vigorous. In the east of the world, with 9.6 million square kilometers of the great country, the take-off of the dragon, many active moving, stirring advanced characters, unknown to them in their jobs, the performance of the glorious and sacred responsibility, they do not than we are a strong body and even their blood and lives, with a firm belief, and always stand in the forefront of the times, and unite and lead the masses to the cause of socialism with Chinese characteristics can be continuously strengthened. In every age, every day in every workplace, there are numerous such as Zhang Side, Lei Feng, Jiao Yulu, Kong Fansen, Changxia heroes and heroines and so on in the interpretation of the great miracle, in the high-days, the thick soil上奏singing of a hero of the victory after another. In their eyes, scrupulously abide by professional ethics of the high pay and generous benefits than the money Money, work diligently to risk one's life passion is the party and the people entrusted to him the best interpretation of their charm for us to build an enduring The monument has attracted a number of Chinese people, shook the hearts of many people, their hearts there is a belief that our great party! Niu, the servant of the people, relying on the firm conviction of the party, the party relying on the infinite loyalty, wrote a beautiful song of devotion. He, like a red flag, is a monument with cast iron and steel is the backbone of the Chinese nation. The cause of the party above all else, the people's interests above all else, humble son of Gan-Ru Niu servant, though gone from us, but his devotion to the cause, diligently for the people, tried their very best to the spirit of , clean and honest, upright servant of the spirit, still deeply moved us, citing our deep consideration. He is the pride of the party and the people will always be a good example for us. From which we see a party member in the party's oath; see a self-clean, upright and thus leave it penniless afterwards a model of the times. From their eyes, we read what is loyalty; from their deeds, we understand the true qualities of a hero. Bo Peng of the youthful, energetic spirit, the noble upright, blinking in the light of them, I think this is the party's advanced nature and a concrete manifestation of the root of the problem. Mentioned here, I feel very excited, very calm, I am a Communist, a disabled worker, I would like to see them as a model for learning for people with passion for the cause of the burning. Now, "maintain the advanced nature of" education has been gradually moving towards a climax, it is the members of each party's love, care, incentive and encouragement, but also the party of political party members in order to improve the quality, purity of the party's ranks, and enhance the cohesion of the party and combat effectiveness of a strong move. Therefore, "maintaining the advanced nature of" Education is the sun plus rain, so that each party member can grow so that our party can always be invincible. In recent years, the party and the state attaches great importance to the cause of persons with disabilities and disability, Hu Jintao has said: "The people with the dignity and rights of some people have taken part in social life, the desire and ability. The history and reality shows that they are also the creators of social wealth. "Today, people with equality, participation, sharing of social life has been turned into a reality. 2005 Spring Festival evening party, "Avalokitesvara" Dance has brought us a tremendous shock, is this the style you are not disabled? Once again confirms the "Love is our common language." However, as we all know, as a result of physical and psychological defects, people with social participation and competitiveness in a weak position to determine their difficulties is a special group in terms of rehabilitation, education, employment, marriage and family, etc. There are a large number of problems and practical difficulties, there is an urgent need for workers in each of us concerned about the disabled, support, and help provide them with real, concrete and effective services. Today, "the full realization of a well-off" has sounded the clarion call, how to develop the cause of persons with disabilities to lead off the side of a well-off people with wealth, it is incumbent upon each of us the responsibility of workers with disabilities. I am a member of the Communist Party is a disabled worker, is also excited about a good person in life, cause a lot of enthusiasm and full of passion, this passion is always surging in my chest, the road with me in persons with disabilities in the course of development, through spring, summer, autumn and winter, through ups and downs, to grow up today. As a disabled worker, charged with representatives of management, service duties of persons with disabilities, more than a decade, such as day, I set strict demands on themselves, and always maintain the correct ideals and convictions, and always bear in mind the purpose of the party, always maintain open up into the married pragmatic style of work and mental state has always been to realize and safeguard the fundamental interests of all persons with disabilities as their bounden duty to implement a whole-heartedly serve the purposes for persons with disabilities, from their starting positions, starting from the ordinary matter, down-to-earth Practicing the "Three Represents", the right to truly be used for people with disabilities, the Department of the situation for the disabled, the benefit for people with disabilities to seek, in close contact with the blood of persons with disabilities, just clean, selfless dedication, and strive to be a Party cadres, people with close friends, in order to achieve the standards of the party's advanced nature. In my speech to a close, I would like to say a few words inside: disability is not the fault of a person with disabilities is the human reproduction and social development in the course of the inevitable and had to pay a social cost, as a deeply YE Mao-tree, the wind, the rain played, there will always be branches of decaying leaves were injured, but we are of the same origin with the same branch of the brothers and sisters. I am a member of the Communist Party on behalf of persons with disabilities, people with disabilities feel pain for people with disabilities the right to use, I should have a high sense of responsibility and mission, a better tomorrow for people with disabilities give their light and heat; I would like to full enthusiasm and tireless efforts in the cause of persons with disabilities to write poems on the most beautiful, party loyalty, safeguarding the interests of the party for the party's cause to fight all his life!你可以根据自己的需要修改。
