Ⅱ 急求一篇大学英语四级考试中关于低碳环保问题的写作作文，谢了！
低碳环保小论文
地球是我们的母亲，毫不保留地为人类提供各种赖以生存的资源，而我们却不知道珍惜，还随意地毁坏自然资，比如森林砍伐，比如废气排放，导致泥土流失，树木被黄沙替代，破坏性风暴增多，生物种类减少，这些都是人类造成的。
科学家发现，至少有100多种大气污染物对环境产生危害，其中二氧化硫，氮氧化合物，一氧化碳，氟氢烃等都对人体有着较大的危害。大气污染物在空气中积累导致空气质量下降，直接危害人类健康，并且使臭氧层受到破坏，致使全球气候变暖。环境问题已经发展成为全球性的问题了，甚至影响着全人类的生存与发展。
气候变暖真的导致灾难吗？人们的疑虑不是没道理的。二氧化碳的排放？这和我们有关系吗？当然，人类只要呼吸便会排放二氧化碳，可是总不能不让我们呼吸吧？这应该是那些轰轰向天空吐出一团团黑烟的化石能源企业的责任吧，化石能源消耗产生的二氧化碳才是导致气候变暖的罪魁祸首。可是我们和那些能源企业的距离真的不相干吗？会有谁想过，这些消耗制造大量二氧化碳的企业最终把生产出来的能量输送哪里？谁又是他们的消费者？我们的日常生活中，电脑，手机，热水器，空调，电灯……哪一样不需要消耗能量？在升入高空的二氧化碳中，你“贡献”了多少？
减少二氧化碳的排放，选择“低碳生活”是每个公民应尽的责任。电脑，电灯，空调，任何电器一旦不用了应随手关掉；手机一旦充电完成，立即拔掉充电插头；

The

To

Some

本次作文还是延续四级一贯成熟的风格，偏重校园生活。当然也结合了时下流行的话题，绿色环保。上面这篇文章尽管有些不妥当之处，但能较好的符合四级考试作文的核心：无论题目怎么变，都是以考察学生的语言为核心，不是考查思维和知识面的。所以只需关注语言的应用就行了。还是可以灵活套用固定的套路，中心句＋逻辑词的方式，做到不变应万变
Ⅳ 大学英语四级作文（环保方面）
A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
一项新的研究结果提出警告：到2025年，世界上将有30%的人没有足够的水饮用。
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
这项研究是由美国一家名叫“人口行动”的私立机构进行的。报告说现在世界上有三亿三千五百万人没有足够的水。这些人主要分布在非洲或中东的28个国家。
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
人口行动组织的研究人罗博特.安格曼说，到2025年大约三十亿人缺水。至少还有其他18个国家将可能面临同样严重的水短缺问题。人类对水的需求不断上升，但地球上水的还是保持不变。
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
安格曼先生说，水短缺的国家的人口增长率要高于世界其他地区的人口增长率。他还说这些国家的人口出生率将持续增长。
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new instries often need a large amount of water when they are beginning.
报告表明，在未来，水资源的缺乏可能会导致一些严重的后果。首先它可能会产生更多的健康问题。水资源的缺乏就意味着饮用水不再有保障。安格曼先生说，诸如霍乱等在水中传播的疾病会使世界出现许多问题。水缺乏也会引起更多的国际纷争。各国可能由于水而发动战争。现在有些国家，例如埃及，荷兰，柬埔寨，叙利亚，苏丹和伊拉克等，60%的纯净水是从国外进口的。报告认为水缺乏将影响发展国家发展经济的能力。这是因为新工业在开始阶段经常需要大量的水。
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
人口行动组织的研究报告为世界的水短缺问题提出了几个解决的办法。第一，找到多用途的用水方法。第二，教育人们不要浪费水资源。第三就是少用农业水。
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.
报告同时表明，控制人口增长是长远解决水缺乏问题不可缺少的措施之一。它说除非各国能通过限制生育来降低人口的增长，否则它们不可能提供干净的水。
Global warming a bigger threat to poor全球变暖加剧贫穷 气候变化急待控制
Global warming, modelled on computer here, kills more people than terrorism
Global warming threatens to reverse human progress, and make unachievable all UN targets to rece poverty(联合国所有减少贫穷的目标), according to some of the world's leading international and development groups.
In a report published today, Oxfam, Greenpeace, Christian Aid, Friends of the Earth, WWF(英国牛津救济委员会、“绿色和平”组织、基督徒互援会、“地球之友”组织、世界野生动物基金组织) and 15 other groups say rich governments must immediately address(致力于) climate change to avoid even "obscene levels(无法忍受的程度)" of worldwide poverty.
"Food proction, water supplies, public health and people's livelihoods are already being damaged and undermined," the report says. "There is no either/or approach possible(想找一个‘非此即彼'的办法是不可能的). The world must meet its commitments to achieve poverty rection and also tackle climate change. The two are inextricably linked(二者的联系是难解难分的)."
The report, which draws on UN predictions of the effects of climate change in poor countries over the next 50 years, says poor countries will experience more flooding, declining food proction, more disease and the deterioration or extinction of entire ecosystems(整个生态系统的退化甚至消失) on which many of the world's poorest people depend.
"Climate change needs to be addressed now. The poor will bear the brunt of the impacts. The frontline experience of many of us working in international development indicates that communities are having to combat more extreme weather conditions."
Climate change will play havoc（大范围的破坏；浩劫） with agriculture and water supplies and will increase diseases. "By 2025 the proportion of the world's population living in countries of significant water stress will almost double, to 6 billion people. Tropical and sub-tropical areas will be hardest hit - those countries already suffering from food insecurity(食品短缺)".
Poor communities mostly do not need hi-tech solutions, but would most benefit from ecation, research and being shown how to farm better. The report says unchecked global warming(尚未得到抑制的全球变暖), more than wars or political upheaval(政变), will displace millions of people and destabilise many countries.
Ⅳ 求篇有关“环境保护”的优秀英语四级作文！
Environmental Protection
No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.
There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.
It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .
环保
没有人,不管是什么种族、宗教或民族、可以否认,我们生活的这个世界变得越来越无法忍受,因为全球变暖的影响。根据许多专家,甚至更大的影响仍在路上。
有许多原因,是我们的问题。一方面,海域排放入大气的碳是导致,必将在未来的事业,具有明显的全球变暖根据理论。另一方面,知识的匮乏有关环境保护的重要性,阻碍了这个问题的解决。
很紧迫的是,应立即采取有效的行动,马上。首先,种植更多的树木需要帮助改善和美化环境。除此之外,更严厉的法律关于全球变暖的燃料资源和不负责任的使用必须付诸实践,取得了较好效果。总之,还有很长的路要走,我们就能采取一种舒适的世界是理所当然的了。
Ⅵ 急求有关环境方面的四级英语作文
Nowadays, a new lifestyle called carbon life is spreading every corner of our country. The conceps of low carbon are low energy and no waste. Firstly, a no-car day is supposed to set up every week in our city. Because cars not only cause serious air pollution but also waste energy. It's a good idea to go to school or go to work by bus,on foot and bu subway. Secondly, we had better not use plastic bags any more. Nobody can stand the "white pollution".As we all know, people can't get the free plastic bags in the shops or supermarkets. Now in this way, people pay more attention to the environment and use fewer plastic bags. Instead of using the plastic bags, we'd better use the cloth bags or use bags which can be reused again and again. Finally, one thing that we should keep in mind, we should turn off the lights when we leave, turn of the tap in time, and reuse our textbooks and bottles. We shouldn't spit in a public place and we shouldn't trow litter onto the ground. We should plant more flowers and trees and we must pick up some rubbish and throw it into the stbin.
In a word, let us try our best to protect the environment. If everyone makes contribution to portecting the environment, the world will become much more beautiful.
