Ⅱ 急求一篇大學英語四級考試中關於低碳環保問題的寫作作文，謝了！
低碳環保小論文
地球是我們的母親，毫不保留地為人類提供各種賴以生存的資源，而我們卻不知道珍惜，還隨意地毀壞自然資，比如森林砍伐，比如廢氣排放，導致泥土流失，樹木被黃沙替代，破壞性風暴增多，生物種類減少，這些都是人類造成的。
科學家發現，至少有100多種大氣污染物對環境產生危害，其中二氧化硫，氮氧化合物，一氧化碳，氟氫烴等都對人體有著較大的危害。大氣污染物在空氣中積累導致空氣質量下降，直接危害人類健康，並且使臭氧層受到破壞，致使全球氣候變暖。環境問題已經發展成為全球性的問題了，甚至影響著全人類的生存與發展。
氣候變暖真的導致災難嗎？人們的疑慮不是沒道理的。二氧化碳的排放？這和我們有關系嗎？當然，人類只要呼吸便會排放二氧化碳，可是總不能不讓我們呼吸吧？這應該是那些轟轟向天空吐出一團團黑煙的化石能源企業的責任吧，化石能源消耗產生的二氧化碳才是導致氣候變暖的罪魁禍首。可是我們和那些能源企業的距離真的不相干嗎？會有誰想過，這些消耗製造大量二氧化碳的企業最終把生產出來的能量輸送哪裡？誰又是他們的消費者？我們的日常生活中，電腦，手機，熱水器，空調，電燈……哪一樣不需要消耗能量？在升入高空的二氧化碳中，你「貢獻」了多少？
減少二氧化碳的排放，選擇「低碳生活」是每個公民應盡的責任。電腦，電燈，空調，任何電器一旦不用了應隨手關掉；手機一旦充電完成，立即拔掉充電插頭；

本次作文還是延續四級一貫成熟的風格，偏重校園生活。當然也結合了時下流行的話題，綠色環保。上面這篇文章盡管有些不妥當之處，但能較好的符合四級考試作文的核心：無論題目怎麼變，都是以考察學生的語言為核心，不是考查思維和知識面的。所以只需關注語言的應用就行了。還是可以靈活套用固定的套路，中心句＋邏輯詞的方式，做到不變應萬變
Ⅳ 大學英語四級作文（環保方面）
A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
一項新的研究結果提出警告：到2025年，世界上將有30%的人沒有足夠的水飲用。
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.
這項研究是由美國一家名叫「人口行動」的私立機構進行的。報告說現在世界上有三億三千五百萬人沒有足夠的水。這些人主要分布在非洲或中東的28個國家。
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.
人口行動組織的研究人羅博特.安格曼說，到2025年大約三十億人缺水。至少還有其他18個國家將可能面臨同樣嚴重的水短缺問題。人類對水的需求不斷上升，但地球上水的還是保持不變。
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.
安格曼先生說，水短缺的國家的人口增長率要高於世界其他地區的人口增長率。他還說這些國家的人口出生率將持續增長。
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.
報告表明，在未來，水資源的缺乏可能會導致一些嚴重的後果。首先它可能會產生更多的健康問題。水資源的缺乏就意味著飲用水不再有保障。安格曼先生說，諸如霍亂等在水中傳播的疾病會使世界出現許多問題。水缺乏也會引起更多的國際紛爭。各國可能由於水而發動戰爭。現在有些國家，例如埃及，荷蘭，柬埔寨，敘利亞，蘇丹和伊拉克等，60%的純凈水是從國外進口的。報告認為水缺乏將影響發展國家發展經濟的能力。這是因為新工業在開始階段經常需要大量的水。
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.
人口行動組織的研究報告為世界的水短缺問題提出了幾個解決的辦法。第一，找到多用途的用水方法。第二，教育人們不要浪費水資源。第三就是少用農業水。
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.
報告同時表明，控制人口增長是長遠解決水缺乏問題不可缺少的措施之一。它說除非各國能通過限制生育來降低人口的增長，否則它們不可能提供干凈的水。
Global warming a bigger threat to poor全球變暖加劇貧窮 氣候變化急待控制
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(聯合國所有減少貧窮的目標), 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(英國牛津救濟委員會、「綠色和平」組織、基督徒互援會、「地球之友」組織、世界野生動物基金組織) and 15 other groups say rich governments must immediately address(致力於) climate change to avoid even "obscene levels(無法忍受的程度)" 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(想找一個『非此即彼'的辦法是不可能的). The world must meet its commitments to achieve poverty rection and also tackle climate change. The two are inextricably linked(二者的聯系是難解難分的)."
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(整個生態系統的退化甚至消失) 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（大范圍的破壞；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變暖), more than wars or political upheaval(政變), will displace millions of people and destabilise many countries.
Ⅳ 求篇有關「環境保護」的優秀英語四級作文！
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 .
環保
沒有人,不管是什麼種族、宗教或民族、可以否認,我們生活的這個世界變得越來越無法忍受,因為全球變暖的影響。根據許多專家,甚至更大的影響仍在路上。
有許多原因,是我們的問題。一方面,海域排放入大氣的碳是導致,必將在未來的事業,具有明顯的全球變暖根據理論。另一方面,知識的匱乏有關環境保護的重要性,阻礙了這個問題的解決。
很緊迫的是,應立即採取有效的行動,馬上。首先,種植更多的樹木需要幫助改善和美化環境。除此之外,更嚴厲的法律關於全球變暖的燃料資源和不負責任的使用必須付諸實踐,取得了較好效果。總之,還有很長的路要走,我們就能採取一種舒適的世界是理所當然的了。
Ⅵ 急求有關環境方面的四級英語作文
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.
