it was the industrial revolution that gave birth to environmental pollution as we know it today. the emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. chicago and cincinnati were the first two american cities to enact laws ensuring cleaner air in 1881. other cities followed around the country until early in the 20th century, when the short lived office of air pollution was created under the department of the interior. extreme smog events were experienced by the cities of los angeles and donora, pennsylvania in the late 1940s, serving as another public reminder.环境污染现象英语作文二

Every one has a different personality. I have an optimistic personality and I always do everything happily. But not every one finds this easy. When I meet people like this, I usually advise them to see the school councilor. There are reasons why everyones personality is so different. If your parents love you and care about you, then your personality will be healthy and happy. If your parents dont, then your personality could sad and withdrawn. A persons personality determines his or her future. So if you come across someone who is often worried, you can try and help them or tell them to seek help from a councilor.

篇3:1汉语环境影响英语写作的几个方面

全文共 743 字

+ 加入清单

1.1词汇方面

如果把写英语作文比作建楼房的话,英语词汇在英语写作中起着砖、瓦的作用,是句子的最基本的组成部分,所以词汇是我们高中英语教学中的重点,单词听写是课堂教学必不可少的一个环节,但学生的词汇量毕竟有限,遇到问题时,便会用汉语词汇去补充英语词汇的空缺。

例如:交通十分繁忙。误:The traffic is busy. 正:The traffic is heavy.

她和一位教授结婚了。误:She married with a professor.

正:She married a professor.

英语词语的词义往往比较复杂,并和汉语有着一定区别。这种不同就会会导致学生仅把写作当作一词一句的翻译来做,结果是事倍功半。

1.2语法方面

英语中难点就是时态,语态的掌握。英语中常用时态共十六种,语态分为主动语态与被动语态,语气有陈述语气与虚拟语气之分。不同的时态有它特有的句法结构。如现在进行时态使用be+v-ing形式来表示。现在完成时则用have/has +p.p来表示。一般将来时则用shall/will/be going to+v来表示。英语中时间意义的表达是通过动词的时和体来加以反映,而汉语中不存在时、体等,汉语则依靠表示时间的副词(如“曾经”、“正在”、“已经”、“将要”)作状语,或利用虚词“了”、“着”、“过”等作补语这一语法手段来体现,动词本身无任何变化。在英语中,“already”和“ever”常常用在完成时态之中,不能与表示过去的时间状语连用。学生常常把上述句子错译成“Yesterday I have been to the park.”“Five years ago,they have known each other.”又如在英语中,我们常常用否定前置来

篇6:当前,威胁人类生存的十大环境问题是

全文共 2072 字

+ 加入清单

(一)全球气候变暖

由于人口的增加和人类生产活动的规模越来越大,向大气释放的二氧化碳(CO2)、甲烷(CH4)、一氧化二氮(N2O)、氯氟碳化合物(CFC)、四氯化碳(CCl4)、一氧化碳(CO)等温室气体不断增加,导致大气的组成发生变化。大气质量受到影响,气候有逐渐变暖的趋势。由于全球气候变暖,将会对全球产生各种不同的影响,较高的温度可使极地冰川融化,海平面每10年将升高6厘米,因而将使一些海岸地区被淹没。全球变暖也可能影响到降雨和大气环流的变化,使气候反常,易造成旱涝灾害,这些都可能导致生态系统发生变化和破坏,全球气候变化将对人类生活产生一系列重大影响。

(二)臭氧层的耗损与破坏

在离地球表面10~50千米的大气平流层中集中了地球上90%的臭氧气体,在离地面25千米处臭氧浓度最大,形成了厚度约为3毫米的臭氧集中层,称为臭氧层。它能吸收太阳的紫外线,以保护地球上的生命免遭过量紫外线的伤害,并将能量贮存在上层大气,起到调节气候的作用。但臭氧层是一个很脆弱的大气层,如果进入一些破坏臭氧的气体,它们就会和臭氧发生化学作用,臭氧层就会遭到破坏。臭氧层被破坏,将使地面受到紫外线辐射的强度增加,给地球上的生命带来很大的危害。研究表明,紫外线辐射能破坏生物蛋白质和基因物质脱氧核糖核酸,造成细胞死亡;使人类皮肤癌发病率增高;伤害眼睛,导致白内障而使眼睛失明;抑制植物如大豆、瓜类、蔬菜等的生长,并穿透10米深的水层,杀死浮游生物和微生物,从而危及水中生物的食物链和自由氧的来源,影响生态平衡和水体的自净能力。

(三)生物多样性减少

《生物多样性公约》指出,生物多样性“是指所有来源的形形色色的生物体,这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;它包括物种内部、物种之间和生态系统的多样性。”在漫长的生物进化过程中会产生一些新的物种,同时,随着生态环境条件的变化,也会使一些物种消失。所以说,生物多样性是在不断变化的。近百年来,由于人口的急剧增加和人类对资源的不合理开发,加之环境污染等原因,地球上的各种生物及其生态系统受到了极大的冲击,生物多样性也受到了很大的损害。有关学者估计,世界上每年至少有5万种生物物种灭绝,平均每天灭绝的物种达140个,估计到21世纪初,全世界野生生物的损失可达其总数的15%~30%。在中国,由于人口增长和经济发展的压力,对生物资源的不合理利用和破坏,生物多样性所遭受的损失也非常严重,大约已有200个物种已经灭绝;估计约有5000种植物在近年内已处于濒危状态,这些约占中国高等植物总数的20%;大约还有398种脊椎动物也处在濒危状态,约占中国脊椎动物总数的7.7%左右。因此,保护和拯救生物多样性以及这些生物赖以生存的生活条件,同样是摆在我们面前的重要任务。

(四)酸雨蔓延

酸雨是指大气降水中酸碱度(PH值)低于5.6的雨、雪或其他形式的降水。这是大气污染的一种表现。 酸雨对人类环境的影响是多方面的。酸雨降落到河流、湖泊中,会妨碍水中鱼、虾的成长,以致鱼虾减少或绝迹;酸雨还导致土壤酸化,破坏土壤的营养,使土壤贫瘠化,危害植物的生长,造成作物减产,危害森林的生长。此外,酸雨还腐蚀建筑材料,有关资料说明,近十几年来,酸雨地区的一些古迹特别是石刻、石雕或铜塑像的损坏超过以往百年以上,甚至千年以上。世界目前已有三大酸雨区。我国华南酸雨区是唯一尚未治理的。

(五)森林锐减

在今天的地球上,我们的绿色屏障——森林正以平均每年4000平方公里的速度消失。森林的减少使其涵养水源的功能受到破坏,造成了物种的减少和水土流失,对二氧化碳的吸收减少进而又加剧了温室效应。

(六)土地荒漠化

全球陆地面积占60%,其中沙漠和沙漠化面积29%。每年有600万公顷的土地变成沙漠。经济损失每年423亿美元。全球共有干旱、半干旱土地50亿公顷,其中33亿遭到荒漠化威胁。致使每年有600万公顷的农田、900万公顷的牧区失去生产力。人类文明的摇篮底格里斯河、幼发拉底河流域,已由沃土变成荒漠。中国的黄河流域,水土流失亦十分严重。

(七)大气污染

大气污染的主要因子为悬浮颗粒物、一氧化碳、臭氧、二氧化碳、氮氧化物、铅等。大气污染导致每年有30-70万人因烟尘污染提前死亡,2500万的儿童患慢性喉炎,400-700万的农村妇女儿童受害。

(八)水污染

水是我们日常最需要,也上接触最多的物质之一,然而就是水如今也成了危险品。

(九)海洋污染

人类活动使近海区的氮和磷增加50%-200%;过量营养物导致沿海藻类大量生长;波罗的海、北海、黑海、东中国海(东海)等出现赤潮。海洋污染导致赤潮频繁发生,破坏了红树林、珊瑚礁、海草,使近海鱼虾锐减,渔业损失惨重。

(十)危险性废物越境转移

危险性废物是指除放射性废物以外,具有化学活性或毒性、爆炸性、腐蚀性和其他对人类生存环境存在有害特性的废物。美国在资源保护与回收法中规定,所谓危险废物是指一种固体废物和几种固体的混合物,因其数量和浓度较高,可能造成或导致人类死亡,或引起严重的难以治愈疾病或致残的废物。

Water pollution on the impact of industrial and agricultural production of industrial and agricultural production not only need to have enough water, but also have some requirements for water quality. Otherwise, the industrial and agricultural industry will cause great losses, especially in the industrial and agricultural production process using contaminated water, the human has a great harm. First, the destruction of industrial equipment, a serious impact on product quality. Second, the chemical composition of the soil changes, fertility decreased, leading to crop reduction and serious pollution. Third, the city to increase domestic water and industrial water treatment costs.

Clean air is the necessary material basis for people to survive, an adult to breathe an average of 15 cubic meters of air a day, if people breathe heavily polluted air, no doubt harmful to health. Therefore, the study of the impact of air pollution, awareness of the value of clean air is a very complex frontier research project.

It can be said that fine particles (respirable particulate matter) is the first killer of human health. According to experts, particulate matter attached to the toxic heavy metals, acidic oxides compared with the soil enrichment hundreds of times, thousands of times, or even tens of thousands of times, and can float in the air up to several days, harmful substances with the inhalation Particles into the human lungs, and may through the alveolar into the blood, directly endanger human health.

Recently, the eight-year research results in Beijing adopted by the State Environmental Protection Administration presided over the expert appraisal. Experts believe that this research results for our understanding of the importance of clean air, improve the public and the leadership of environmental awareness is of great significance. The data of the research results provide a scientific basis for the national air environment legislation, the development and revision of air quality standards, emission standards and air pollution control policies.

The proposal is from Wang Yuqing, a deputy director of the Committee of Population, Resources and Environment.

He is being quoted as saying he favors a gradual opening of a two-child per family policy, and says he believes the current limitations will be lifted by the end of the five-year plan in 2015.

The current family planning policy was initiated in 1979 to control Chinas rapidly growing population.

But some negative side effects have emerged, including a rapidly aging population.

Peng Xizhe is the Director of the Institute of Population Research at Fudan University.

"The one-child policy has fulfilled the goal initially set. Negative effects will pile up if it continues."

The President of Renmin University, Ji Baocheng, claims the labor force population between the ages of 28 and 40 will be halved in 10 years.

As an example, in Shanghai, which has the highest urban population in China, the number of Shanghai natives -- as in those with a Hukou -- has actually been dropping for the last 17 years in a row, even though the citys population has been increasing.

A possible reason for Shanghai parents not choosing to have a second child could be the rising cost of everyday expenses, particularly the cost of education.

"I dont think Ill have a second child if the limit is removed. Im simply a wage-earner, and I find it difficult enough to raise one child, so I wont consider the second."

But at the same time, there are still people who think it would be nice to have two children.

"I will think about it. A lot of parents now are the only child in families, to have two kids means they can look after each other in the future, and of course, therell be financial burden."

One-Child Policy has been relaxed in certain ways over the years.

In cities such as Shanghai and Beijing, if a couple is both the product of the one-child policy, theyre allowed to have two kids.

Certian ethnic minority groups have been exempt from the rules entirely.

And families in rural areas whose first child is a girl are also allowed to have a second child without punishment.

It remains unclear as to how the proposed two-child policy will work, though its being suggested that several big cities will be selected to try it before its brought in around the country.

For CRI, Im Wang Jing.

导语:现如今环境污染越来越严重,我们应该保护环境!下面是yuwenmi小编为大家整理的相关英语作文,欢迎阅读与借鉴,谢谢!

Many 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 environment. Though 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 situation.

Measures 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 problems.

Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.

【参考翻译】

很多人都活跃在对抗不公平待遇有色人种、妇女、动物等。现在我谈论要争取尊重我们的环境。尽管环境没有嘴巴来反对人类对她所做的一切,她通过行动来报复。在早些年中国人在黄河的源头大量砍伐树木,导致了大森林的消失和可怕的洪水。结果,曾经一度覆盖草地和森林的黄土高原变成了植物稀少的荒漠。另一个例子是在一些发达国家。因为许多化学工厂没有过滤就排放有毒气体,城市充满了如此多的有毒气体,人们通过呼吸这些空气收到伤害。这是多么可怕的场景!

我们所痛苦的是只有一小部分的自然曾经收到破坏。如果我们不采取行动,尊重环境,我们将不得不面对一个日益糟糕的情形。

保护环境应采取我们依赖的措施。首先政府应该禁止污染植被、河流和湖泊、海洋和大气。第二,应该宣布公众保护环境的重要性。第三,企业应特别注意对环境的影响和解决方案的问题。

只有通过改变我们对待环境的方式,我们才可以相处得很好。只有拯救环境,我们才能拯救我们自己。

谁在这儿叹息呀?原来是小鸟,它是在为人类而叹息。因为大森林的树木要被人们砍伐了。如果大树被砍完了,森林里的动物就没有了家。如果大风来了没有了树木的帮助,房屋要倒塌。如果树木被砍了,人们就听不到小鸟叽叽喳喳的叫声,这个世界就只有人类在说话。

Who here sigh? The birds, it is for the human sigh. Because the forest of trees to be cut down. If the tree was cut down in the forest, the animal has no home. If the wind to help without trees, houses collapsed. If the trees were cut down, people can not hear the birds chirping, the world is only a human talking.

请大家爱护环境吧。

Let us care for the environment.

Through observation, I found that plastic bags on peoples harm and pollution is very large. People often use plastic bags: mother to buy food and plastic bags; to shopping malls with plastic bags; in the restaurant to eat rice is also packaged with plastic bags to take home; even I buy stationery also with plastic bags. People do not know what they do to the environment caused by pollution, their own body caused any harm. Such as: people often put useless plastic bags thrown into the garbage, plastic bags in the rubbish will be smelly, so that the pollution of the air. People also throw plastic bags anywhere, a wind, plastic bags flying in the sky, the branches also see the tree is a plastic bag, and even the river there are plastic bags. This plastic bag in addition to pollution of the air, but also polluted our water resources.

We should raise peoples awareness, tell us the neighbors and friends and family together to beautify our environment. On the road to see the plastic bag quickly picked up, immediately took it to the garbage disposal. We want to start from my use less plastic bags, so that my mother every day to buy food or shopping when they first take their own bags, this is not very environmentally friendly? Or can use their own holding things as far as possible by hand, no plastic bags.

As the saying goes: "to protect the environment, everyone is responsible" We have to protect the home environment out of a force.

我国的城市河流和湖泊污染情况是非常严重的,城市河流有不同程度的富营养化问题。以下是小编给大家整理的形势政策论文:城市水环境的问题探讨的内容,欢迎大家查看。

摘要: 随着经济快速发展,城市生态形势压力也与日俱增,水环境问题已成为制约社会发展的大问题,环保基础设施建设严重落后,城市生活污染物未得到有效控制,工业污染源未得到严格治理,农业污染日益突出,部分河段水质受污染严重,河水发黑发臭,完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词:城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分,城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响,我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失,造成了城市生态环境、水环境的进一步恶化。针对这样的情况,我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发,恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型,由于城市人员密集、工业化生产程度高,所以,城市用水需要较高的质量、较大的供水量、稳定的供给,这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高,所以,单纯依靠城市区域的供给和开采往往难于满足城市发展的需要,因此,大众城市往往需要从城区周边或外地调水来满足城市的用水需要,“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方,城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中,在日积月累的大量污染的影响下,城市水环境受到了严重破坏,并且这一现象有蔓延和恶化的趋势,造成水环境的脆弱和生态的破坏,影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个,一是,城市生产和生活中大量污染源渗入地下,造成对地下水资源和水环境的破坏;二是,城市地表硬化导致城市地面下渗量的减少,在大量开采地下水的同时,没有必要的补充,出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本,科学发展

把维护广大人民群众的根本利益作为第一点,把群众最关心、最直接和现实的水环境保护问题为重点,转变发展观念,重视生态文明建设,加快建设资源节约和环境友好社会,走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品,水环境治理应突出重点,优先保护饮用水源,确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩,把COD削减量考核指标纳入到区县水环境治理目标体系中,明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标,即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金,对节能减排效果明显,有一定经济基础,技术条件成熟,符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集,污染来源复杂。为此,河道治理将坚持“先截污、后清淤、先治理、后换水”的原则,周密排查河道沿线污染来源,大力实施清淤、截污、生态护坡、河岸绿化等措施,加强河道水体自净和生态修复功能;在突出截污治理的同时,各区县还将坚持污水处理厂、配套管网同步建设,大力提升现有污水处理厂运行负荷率,妥善解决污水出路,切实提高河道水环境质量。

5、加强协作,落实责任

市水务局于去年成立了河道水环境考核办公室,将清水工程已治理河道纳入考核范围,各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制,有效巩固水环境治理成果。此外,目前市政府已正式批准本市河道水环境实施“河长制”管理意见,即将公布全市主要河道“河长”名单,构建完善的河道水环境管理长效机制,为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述,我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。
