What Environmental Disaster? We have developed a huge and thriving society; and in the process we deforest huge sections of land for living and livestock grazing. This decreases oxygen and increases carbon dioxide in the atmosphere; possibly adding to global warming though the greenhouse effect. This mass population produces mass amounts of waste, so to deal with that we just throw it into the ground, which in turn contaminates our water supply and contributes to further deforestation. We develop motorized transportation; and then burn non-renewable fossil fuels that put lead, carbon monoxide, sulfur and nitrogen oxides, ozone, excess carbon dioxide, and other harmful particulates into the atmosphere (Skjel & Whorton 95-108). This produces dangers like smog and cancer and contributes to global warming. In the production of fuel we exhaust oil reserves and pollute the oceans through spills from tankers. This endangers wilderness and wildlife. We produce an inert, easily producible propellant for aerosols; and then realize it's only inert on the ground. Once it's bombarded by UV ray in the upper atmosphere it releases a highly destructive ion that wreaks havoc on the protective ozone layer shielding us from those same deadly UV rays, creating a hole in the layer allowing the radiation through, increasing cancer and other genetic defects. We build rockets capable of going into space and breaking the earth's gravitational pull; and then immediately start to pollute this new environment with spent rockets and boosters along with other miscellaneous particles of debris (Curran and Haw 3). Michael Crichton writes, "What we call nature is a complex system of far greater subtlety than we are willing to accept. We make a simplified view of nature and then botch it all up. ...You have to understand what you don't understand. How many times must the point be made? How many times must we see the evidence? We build the Aswan Dam and claim it is going to revitalize the country. Instead, it destroys the fertile Nile Delta, produces parasitic infestation, and wrecks the Egyptian economy" (Jurassic Park 91). To the common person our current situation contains little hope. All the advancement and improvements have done little to further our species. With each one has come a new environmental issue. You almost need to evaluate each situation in terms of positives and negatives. However, at the root of all this chaos you'll find anthropocentrism, a human centered way of thinking. This way of thinking as an attitude, and moral theory, centers on humans as the highest of the significant beings. The theory views nature and the environment in terms of their use value for humans only (Michaels 7). So all of the above developments with costs can be justified through their usefulness for humans. The human centered ethic is deeply rooted in the past through the ancient Greek and Roman societies. To pursue further development based on this ethic would be disastrous. With our current numbers of population and rate of growth we're just asking for an environmental catastrophe of the highest magnitude to act as a wake up call. Granted that a great deal of the population realizes that unless action is taken today then we'll have to face that disaster tomorrow. The principle question is how to go about alleviating and repairing the damage we've already caused. We also need to address how to prevent doing further damage for the sake of future generations. The only problem with this view is that it is still a human centered ethic. It still sees the environment as a thing to be utilized by humans for their own pleasure. It doesn't do enough. The problems aren't getting fixed. Better ways of doing things are being researched, but the underlying problem is not receiving any attention. So the environmental downward spiral is only slowed down and is not fixed. We've still got the same problems. To take the conservationist attitude further you would see all sentient beings as holding moral standing and due consideration. This includes most of the animals in the world; any animal capable of experiencing pleasure and pain. Through these experiences you form the basis for the extended moral theory. If the animals perish through their habitat's destruction or outside influences, then their future pleasures will no longer be. When you take into account whole societies and communities of animals then the added value to the environment increases exponentially as you combine their happiness with the happiness never experienced by their future generations (Singer 275-276). So by taking this viewpoint you place even more intrinsic value on the environment through the experiences of all sentient animals involved. But at a time when our behavior may well lead us to extinction, I see no reason to assume that we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion" (The Lost World 7-8). Granted this does not present a case for sentience on the basis of pain vs. pleasure, but it does present an interesting way to think about classifying sentience. So you can see drawing the cut off line for even lower animals could present considerable challenges. You have trouble reaching an adequate definition of "sentient." You are now facing how much awareness a creature has to perceive pain and pleasure along with joy from anticipation of future events to consider it morally significant. If a cat is significant, but not a fish, what makes the cat a moral patient while the fish is not? Where is there a difference? There is a problem of arbitrarily assigning moral value when actual feelings and emotions are beyond description. To go a step further away from human sentience you would hold all living thing to be of moral value. This would then bring plants and non-sentient animals into the picture. This view holds life as the ultimate intrinsic value. Beings have moral value in just being alive. So life is viewed as an intrinsic good, and no verifying pleasures or pains being experienced are needed to allot this worth. Anything living is held with a reverence for that life (Singer 277-278). 2】The Environmental Revolution - We Can Make a Difference! Since the first time having blown bubbles in my Open Water class, I've logged over 100 dives. This love for diving has evolved into an intense passion towards protecting the ocean, and all of its inhabitants. I've chosen to put my love for the ocean into action, as an environmentalist. Actually, this passion extends out towards efforts that look to help all the planetary domains gain protection. As such, I appreciate when others take the time educate me on those other realms for which I know less about. To be an environmentalist, one must choose the cause which resonates within ones sole, and run with it. One must be willing to educate people about the environment while being open to education from those people who support other causes. Together we can help each other towards learning how to become a true "Environmentalist". We must all encourage positive collaboration and education as opposed to being against something. For example, sharks are being decimated to near extinction simply for their fins. The fins are used to make Shark Fin soup, a delicacy popular particularly in Taiwan and Singapore. It would be easy to blame these communities for creating the demand. However, in conversing with Asian environmentalists, they liken the culture around eating Shark Fin soup to the culture surrounding Americans eating turkey for Thanksgiving dinner. There are ongoing efforts to educate these people, by members of their own community, on just how dangerous this cultural practice is and the devastating impact this could have on their (our) world if all the sharks were to disappear as a result. Environmentalists everywhere are making a difference! Famous restaurants have taken endangered Swordfish off their menus, these same restaurants are buying wild-caught salmon (and boosting the economy of local fisheries in the process), laundromats have started selling green detergent, this just to name a few of these enlightened changes. This is how the "Environmentalist" can begin the revolution. Just find something you believe in and make a stand. One by one, we can make our planet a cleaner place to live, steeped in healthy bio-diversity for generations to come. 3Giving 1% to Protect Our Environment Though most of the world's surface is covered by water, since the Earth is so large relative to human horizons, there doesn't appear to be a shortage of land. However, when one begins to think of land in terms of a human resource, ., a producer of food, a provider of wood, an expanse for passage, one realizes that many portions are either too lacking in nutrients, too high in elevation, too prone to flooding, or too cold or ice-ridden for extensive use. Furthermore, habitable lands are becoming less abundant due to desertification (the expansion of deserts due to the misuse of land), agricultural expansions and rising sea levels. Since humans aren't the only species that need land, it isn't surprising that this resource is becoming limited for other forms of life too. In part as a result of this added stress on living things, we are also witnessing extinctions of grand proportions-at a rate of many thousands species per year. Since these losses are largely due to human actions, such as deforestation and non-native species introduction, many are beginning to pay attention to how we use and protect land. Recent ecological research has also recently provided a message of hope concerning the future well-being of life on this planet. In the world today, scientists estimate that the Earth is losing at least 1 percent of species every ten years, and the percentage loss may be close to 5 percent. Even if only the lower rate persists, the Earth will have lost near half of its biological diversity by 2070. Can this be possible? Many esteemed scientists think so. While the future appears bleak, several recent insights tell us that we have the potential to significantly reduce what amounts to a biotic holocaust, one not witnessed on Earth for over 60,000,000 years. While there are hopeful signs in the area of human activities (such as increased acreage of nature preserves and national parks), the hope of which I speak of here stems from specific characteristics of the other forms of life which may enable us to mutually coexist in the long term. The Earth's organisms are wonderfully varied in size, shape, function, behavior, and genetic code. One only need to consider that there are ~ 15,000 species of butterflies and ~50,000 species of mushrooms worldwide to begin to fathom the immensity of variety that this planet has. Yet, as different as the species come, the bulk of living things are also similar in a couple of very important ways. Most living things live in relatively small regions and do not travel far from where they or their parents were born. In fact, recent biological and ecological work has determined that most land species are very particular about where they live. As opposed to humans whose choice of home is largely driven by economic and political forces (mobility driven by availability of wealth or forced relocation), flora and fauna find themselves in locations for which they are adapted. We now know that many species of insects and plants have a very restricted range in which they found. Very few organisms are ubiquitous like we are. It goes without saying that you aren't going to find a Great Blue Heron or a Grizzly visiting Antarctica or climbing Mt. Everest; yet you might find the snow bear (recently discovered and previously known as the Abominable Snowman) doing the latter. Recognizing that most living things are rather localized during their lifetimes has profound implications, both hopeful and cautious. On the one hand, it suggests that we can learn a lot about species by parking our scientific minds in specific locations. On the other hand, it means that if we destroy even small areas of the globe we are likely causing great and even irreversible destruction to the species that are found there. We have also determined that there are specific locations on our planet where a disproportionate number of species live. For our species, Asia serves as the homeland for most. In fact more than 60 percent of humans lives on this largest of continents (which only makes up 24 percent of the land surface on the planet). With other life forms, geographic concentrations sometimes defy description. We only recently became aware that the vast majority of terrestrial (as distinguished from oceanic or riparian) species collectively live on just 1 percent of the Earth's land surface. (If humans lived at a comparable concentration level, we'd all have to cluster together in an area roughly the size of Antarctica or twice that of Australia.) This mind-blowing realization has prompted those that have been struggling to protect organisms a new way of thinking about such protection. They have concluded that if we humans could somehow find a way to avoid disturbing just 1-2 percent of the land surface, nearly 70 percent of the world's terrestrial species might be able to survive. Recently some conservationists have refocused their attention on these unique locations. The regions of the globe that contain such a splendid array of biological diversity have been named "hot spots," a name that communicates their critical status. In what has to be the most beautiful books I have seen, Hotspots represents the collective work of scientists Russ and Cristina Mittermeier and Norman Myers as well as photographer Patricio Robles Gil. In this oversized volume, these four scholars have assembled more than three hundred vivid photographs of some of the world's endangered species and threatened ecosystems. These absolutely breath-taking images come from the what they refer to as "the 25 most critically important regions" in the world. These regions originally constituted almost 12 percent of the world's land surface but now, due to human pressure at many levels, only a little more than 1 percent remains intact. What makes these locations, which are found on all continents except Antarctica, so "hot" is that they are home to hordes of the Earth's plants and animals and they face imminent danger from a variety of human activities. The Hotshot authors and others strongly believe that the global community can do wonders if these areas move to the top of our priority list. But what will have to happen for these spots to be protected? There are no simple answers to this central question. Unfortunately, those of us in the United States who have the luxury of time to even ponder such questions, face many obvious difficulties. First, nearly all of the hotspots are located outside of our territorial boundaries, exceptions being the forests of Oregon and California as well as portions of Southern Florida (namely the Keys and the Everglades). Key hotspots are found in New Zealand, Madagascar, and Indonesia as well as the continental parts of south-east Asia. Obviously we cannot expect that we will be able to force other countries to enact and enforce laws that will greatly reduce biological degradation. Yet, while many other countries have ratified the Biodiversity Treaty that was drafted at the 1992 Rio Earth Summit, it has never reached the floors of the . Congress for a vote; Canada, Japan, and the European Union are among those to ratify it. By this inaction our nation apparently lacks the wherewithal to support global conservation efforts as a matter of principle. However, given that the wealthy nations in concert with international banks promote unsustainable extraction of resources in the world's developing countries, it would appear that we have an obligation to do so. If our national policy makers are unwilling to commit themselves to the protection of global ecosystems and species, we still have ourselves to look to for sources of positive change. All of us have tremendous purchasing power, especially in comparison to the majority of the other human residents on this planet; Barry Bearak, a Pulitzer Prize-winner journalist who recently spoke at Knox College's convocation, referred to the residents of the United States as "filthy rich," a conclusion he came to after spending a great deal of time in the poorer regions of the world, particularly Afghanistan and India. What we buy makes a difference. The environmental campaign to support shade coffee rather than sun coffee is just one of many attempts for the consumer to support sustainable practices in regions of great ecological diversity. According to the Northwest Shad Coffee Campaign, shade coffee agricultural allows for the extraction of a desired resource but at the same time allows between 3-8 times as many birds species to persist not to mention many more mid-size mammals as well as amphibians and beetles. Coffee is also a particularly important commodity in terms of the health of ecological systems because the countries that produce the bulk of it are precisely the same countries that are home to the majority of the world's species; the countries of Brazil, Bolivia, Indonesia, Vietnam collectively produce ~40 percent of the 17 billion pounds of coffee that are harvested each year (folks, that's more than 3 pounds per person!). Burdensome debts also force many developing countries to endlessly delay infrastructure investment. Debt-for-nature swaps, an idea proposed by Dr. Thomas Lovejoy of the World Wildlife Federation in the mid-1980s, have enabled poor countries to relieve foreign debt and international nongovernmental organizations (NGOs) to increase commitment to conservation programs both at the same time. In these swaps, NGOs pay off a poor country's debt to a bank or well-to-do country at greatly reduced costs in order to establish agreements for investment in national parks, for example. While not a cure-all, these efforts have begun the paradigm shift from unabated expansion and unhealthy extraction to one supportive of saving natural ecosystems and securing the health and welfare of all human populations. Threats to these locations represent massive scale intrusions taken by societies found on every continent. Unfortunately, there is so much that will be lost if these "special" places aren't quickly protected from future degradation. On the bright side though, so much of the world's genetic diversity lives in just a couple handfuls of "hotspots" that if these locations were saved hordes of species would be able to persist into the next millennium. The time is now to respond to this fairly recent observation and insight. It is time for the world to begin to act like a civilized 21st Century society. It is incumbent upon us, those with time and wealth, to maintain the momentum that others have started. The masses of life forms are relying on us to make the best attempt at this daunting yet critical task. Hopefully our species will be sensible enough to leave at least 1 percent of land alone, so that other life forms may continue to exist. Do we need all 100 percent? 写不下了，如果觉得不够，邮箱可否留一下，我继续补充
The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially. Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment. Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks. So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life.英语作文常见话题-环境保护 Protect EnvironmentMany people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our the environment doesn’t have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result，the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we don’t take action to show respect to the environment, we will have to face an increasingly awful should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.

Coffee is also a particularly important commodity in terms of the health of ecological systems because the countries that produce the bulk of it are precisely the same countries that are home to the majority of the world's species; the countries of Brazil, Bolivia, Indonesia, Vietnam collectively produce ~40 percent of the 17 billion pounds of coffee that are harvested each year (folks, that's more than 3 pounds per person!). Burdensome debts also force many developing countries to endlessly delay infrastructure investment. Debt-for-nature swaps, an idea proposed by Dr. Thomas Lovejoy of the World Wildlife Federation in the mid-1980s, have enabled poor countries to relieve foreign debt and international nongovernmental organizations (NGOs) to increase commitment to conservation programs both at the same time. In these swaps, NGOs pay off a poor country's debt to a bank or well-to-do country at greatly reduced costs in order to establish agreements for investment in national parks, for example. While not a cure-all, these efforts have begun the paradigm shift from unabated expansion and unhealthy extraction to one supportive of saving natural ecosystems and securing the health and welfare of all human populations. Threats to these locations represent massive scale intrusions taken by societies found on every continent. Unfortunately, there is so much that will be lost if these "special" places aren't quickly protected from future degradation. On the bright side though, so much of the world's genetic diversity lives in just a couple handfuls of "hotspots" that if these locations were saved hordes of species would be able to persist into the next millennium. The time is now to respond to this fairly recent observation and insight. It is time for the world to begin to act like a civilized 21st Century society. It is incumbent upon us, those with time and wealth, to maintain the momentum that others have started. The masses of life forms are relying on us to make the best attempt at this daunting yet critical task. Hopefully our species will be sensible enough to leave at least 1 percent of land alone, so that other life forms may continue to exist. Do we need all 100 percent? 写不下了，如果觉得不够，邮箱可否留一下，我继续补充
The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially. Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment. Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks. So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life.英语作文常见话题-环境保护 Protect EnvironmentMany people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our the environment doesn’t have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result，the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we don’t take action to show respect to the environment, we will have to face an increasingly awful should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.
There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities. To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today. In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves. 保护环境 目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。 为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。 我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

特别说明：凡出现在“参考文献”项中的标点符号都失去了其原有意义，且其中所有标点必须是半角，如果你的输入法中有半角/全解转换，则换到半角状态就可以了，如果你的输入法中没有这一转换功能，直接关闭中文输入法，在英文输入状态下输入即可。
其实，很多输入法(如目前比较流行的搜狐输入法)都提供了四种组合：
(1)中文标点+全角：这时输入的标点是这样的，：【1】-(而这时，我没有找到哪个键可以输入/符号)也就是说，这些符号是一定不能出现在“参考文献”中的;
(2)中文标点+半角：这时输入的标点是这样的，：【1】-(这时，我还是没有找到哪个键可以输入/符号)也就是说，这些符号也不能出现在“参考文献”中的;
上面列出的符号，中间没有任何的空格，你能看出它们有什么区别吗?我看只是-的宽度有一点点不同，其它都一样
(3)英文标点+全角：这时输入的标点是这样的，.:[1]-/
(4)英文标点+半角：这时输入的标点是这样的，.:[1]-/
从这两项可以明显的看出，半角和全角其实最大的差别是所占的宽度不一样，这一点对于数字来说最为明显，而英文标点明显要比中文标点细小很多(也许因为英文中，标点的功能没有中文那么复杂，就是说英文中标点符号的能力没有中文那么强大)
所以，很多人在写“参考文献”时，总是觉得用英文标点+半角很不清楚，间距也太小，其实这点完全不用担心如果你觉得真的太小不好看，就用英文标点+全角吧而在[1]之后，一般也都有一个空格。
对于英文参考文献，还应注意以下两点：
①作者姓名采用“姓在前名在后”原则，具体格式是：姓，名字的首字母。如：Malcolm Richard Cowley 应为：Cowley, .,如果有两位作者，第一位作者方式不变，&之后第二位作者名字的首字母放在前面，姓放在后面，如：Frank Norris 与Irving Gordon应为：Norris, F. & .
②书名、报刊名使用斜体字，如：Mastering English Literature,English Weekly.
三、注释
注释是对论文正文中某一特定内容的进一步解释或补充说明注释应置于本页页脚，前面用圈码①、②、③等标识。
根据学术堂的了解，参考文献是英语论文的重要组成部分，也是编辑加工和重要内容。接下来就为大家介绍英语论文参考文献格式要求，欢迎阅读。I.文内引用(一)直接引用1.引用中的省略原始资料的引用：在正文中直接引用时，应给出作者、年份，并用带括号的数字标出页码。若有任何资料省略，使用英文时，应用3个省略号在句中标出(…)，中文用6个(……);若两句间的资料省略，英文应用4个省略号标出(‥‥)，中文用6个(……)。若要在直接引用插入自己的解释，应使用方括号[ ]。若在资料中有什么错误拼写、错误语法或标点错误会使读者糊涂，应在引用后立即插入[sic]，中文用[原文如此]。下面是一些示例：例一：The DSM IV defines the disorder [dysthymic] as being in a chronically depressed mood that occurs for "most of the day more days than not for at least two years (Criterion A) .... In children, the mood may be irritable rather than depressed, and the required minimum duration is only one year" (APA, 1994, p. 345).例二：Issac (1995) states that bipolar disorder "is not only uncommon but may be the most diagnostic entity in children and adolescents in similar settings .... and may be the most common diagnosis in adolescents who are court-remanded to such settings" ().2.大段落引用当中文引用超过160字时，不使用引号，而使用“块”的形式(引用起于新的一行，首行缩进4个空格，两端对齐，之后每行都缩进)。当英文引用超过40字时，不使用引号，而使用“块”的形式(引用起于新的一行，首行缩进5个空格，左对齐，之后每行都缩进)。Elkind (1978) states:In general, our findings support Piaget's view that perceptionsas well as intelligence are neither entirely inborn nor entirely innate but are rather progressively constructed through the gradual development of perceptual regulations. The chapter has also attempted to demonstrate the applicability of Piaget's theory to practical issues by summarizing some research growing out of an analysis of beginning reading. ()(二)间接引用1.基本格式同作者在同一段中重复被引用时，第一次必须写出日期，第二次以后则日期可省略。a.英文文献：In a recent study of reaction times, Walker (2000) described the method…Walker also found…。b.中文文献：李福印(2004)提出概念隐喻的重要性，…;李福印同时建议…。2. 单一作者a. 英文文献：姓氏(出版或发表年代)或(姓氏，出版或发表年代)。例如：Porter (2001)…或…(Porter, 2001)。b. 中文文献：姓名(出版或发表年代)或(姓名，出版或发表年代)。例如：杨惠中(2011)…或…(杨惠中，2011)。3.两个作者英文引用时，在圆括号内使用两名作者的姓氏，并使用“&”来连接，在正文中，使用“and”连接两名作者。中文引用时，在圆括号内使用两名作者的姓名，并用顿号“、”来连接，在正文中，使用 “和”、“与”、“及”等字连接两名作者。例如：(Smith & Jones, 1994), or Smith and Jones (1994) found....In 1994 Smith and Jones researched.... Always cite both names in text.陈国华和田兵(2008)认为…或…(陈国华、田兵，2008)4.三至五个作者英文第一次引用参考资料时，列出所有的作者的姓氏，除最后一名作者之前在正文中使用逗号加“and”、在圆括号内使用逗号加“&”连接外，之前的其他作者之间使用逗号“，”;之后引用时，英文用第一个作者的姓随之以“et al.”。中文第一次引用参考资料时，列出所有作者的姓名，除最后两名作者之间用“和”连接外，之前的其他作者之间使用顿号“、”;之后引用时，用第一名作者加“等”字。例如：Strasburger, Jorgensen, and Randles (1996) found differences.... (第一次使用).Strasburger et al. (1996) also created tests.... (在段落中第二次使用).Starsburger et al. found discrepancies.... (在同一段落中再次使用，此时省略年份).卫乃兴、李文中与濮建忠(2005)指出…或…(卫乃兴、李文中、濮建忠，2005)。(第一次使用)卫乃兴等(2005)指出…或…(卫乃兴等，2005)。(第二次使用)5.六个作者及以上使用英文时，只用第一个人的姓氏加“et al.”;使用中文时，只列出第一名作者的姓名，再加上“等”。例如：Pouliquen et al. (2003)……或……(Pouliquen et al., 2003)王洪俊等(2007)…或…(王洪俊等,2007)6.团体作者使用中文时，第一次用全称，比如，(首都师范大学教育科学学院[首师大教科院]，2001);之后可以用简称，比如，首师大教科院(2001)的调查表明……。使用英文时，第一次引用时，拼出团体，比如, (National Institute of Mental Health [NIMH], 1996);以后用团体缩写加年份表示，比如，The NIMH (1996) examined....。7.没有作者的文献当一部作品没有作者时，在文中引用参考文献目录单中的前几个字(通常是标题)和年份。比如，一项关于成年人抑郁症的调查(“Study Finds”, 1997)报告……。当某作品的作者列为“Anonymous”、中文使用“匿名”或“无名氏”时，英文引用时用“Anonymous”加逗号及年份，即(Anonymous, 1997)，中文用“匿名”加逗号及年份，即(匿名，1997)。8.英文文献作者姓氏相同英文文献作者姓氏相同时，相同姓氏之作者于论文中引用时均引用全名，以避免混淆。例如：R. D. Luce (1995) and G. E. Luce (1988)…。9.多篇文献a. 多篇文献，同一作者若一作者有多篇你想引用的文献，只需用逗号“，”来区隔作品的发表年份(最早到最晚依序排列)。若多篇文献在同一年内发表，请在年份后面加上a、b、c……等标注。(按：abc的使用需与参考文献部分有所对应，而这些文献的编排以标题名称的字母来决定。)例如：1)A recent study found a possible genetic cause of alcoholism (Pauling, 2004, 2005a, 2005b).2)Pauling (2004, 2005a, 2005b) conducted a study that discovered a possible genetic cause of alcoholismb.多篇文献，多位作者文献依姓氏字母(笔画)、出版年代等顺序排列，不同作者之间用分号“;”分开，相同作者不同年代之文献用逗号“，” 分开。例如：…(Pautler, 1992; Razik & Swanson, 1993a, 1993b)。例如：…(董伟，2010;周音，2011a，2011b)。

So you know how important the environment is. 保护环境是我们的义务。我们居住在哪里？地球。地球是我们唯一居住的地方，所以可想而知环境对于我们的重要性。But now, some people are harming the environment, like cutting down trees, drawing pictures on public walls, littering onto the ground. It's terrible if we still do it. 但是现在，很多人都在破坏环境，比如砍伐树木，在公共墙壁上乱涂乱画，随地扔垃圾。如果我们继续这样下去是非常可怕的。Now, it's time for all the people in the society to protect the environment. It's our duty. It needs each of us to make a contribution to improving the environment. We should make our environment more and more beautiful.现在，是人们保护环境的时候了，这是我们的义务，我们都要为改善环境做贡献，我们应该努力让我们的环境变得更好。
有关环境保护的英语作文 （1） With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life. My suggestion is we should ride bikes more often instead of driving riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends? 与我们的生活水平的提高,越来越多的人都买得起汽车的。因此,道路往往没有堆满了汽车。然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重。所以现在我们提倡过低碳的生活。 我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境。为什么不试试,我亲爱的朋友?（2） Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment. 现在，我们身边的汽车不断的多了起来，环境也越来越糟糕！以至于我们周围的空气有很多有害物质。所以，我们要苏身边的小事做起。比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。有时间的话可以少用电梯，多爬楼梯。我们不仅能锻炼身体,也能保护我们的环境。（3）文章文体：议论文。 文章要点：1.保护环境的重要性；2.学生在家庭中节约能源的具体做法和感想；3.今后的打算。 文章框架：文章应该是三部分两段式。第一段（包括要点前两部分）1.环保的重要性；2 接着是站在学生的角度谈谈家庭节约能源的具体方法，第二段写第三要点，即谈谈今后打算。 重要句型短语：It is important to protect our environment, the energy in the world is limited. turn off the light and other appliance when you ,re not using them, we'd better not waste the energy, use public transportation, recycle the waste，I can learn more to develop new and clear energy, like the energy from the wind and solar 等。 参考例文： With the development of our society, energy in the world becomes more and more limited, so it is quite important for us to save energy and to protect our environment. As a student, there are a lot of methods we can do to save energy at home. For example, first, we can turn off the light as well as other appliances when we are not using them. Second, recycle the waste water, paper and other waste so that we can reuse them. What's more, it is suggested to use public transportation more instead of private cars. Above all, everyone can make a great contribution to our environment. I hope I can learn more to develop new and clear energy, like energy from the wind and solar.（4）Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful.

One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.保护环境目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。
