cars have created a lot of serious problems in our world. all the time, they are pumping huge amounts of waste gases into the atmosphere, causing disease and even death.

one possible solution is to design and develop clean cars and clean fuels. but it may take decades for the new models to completely replace the traditional ones.

another solution is to develop modern public transportation systems and restrict the use of private cars. if the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not drive private cars. on the whole, the elimination of air pollution needs the co-efforts from the government and the public. this problem will be solved only with the help of science and technology.

当今社会正以迅猛之势飞速发展,归根到底是高新技术产业的进一步深化。不容乐观的就是环境与发展之间的问题还没有得到彻底根除。而下面便是小编整理的关于环境问题英语作文 。

环境问题 英语作文【1】

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.

环境问题 英语作文【2】

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 cars.

By riding a bike, we can not only exercise our body but also protect our environment.

Why not have a try, my dear friends?

环境问题 英语作文【3】

Recently,fog and haze has become a imminent threat which most northerners in China are facing.

While the cities of China have greeted striking speed of development with open arms,they suffer greatly from a persistent and dense haze of pollution and smog.

It is high time that we took some methods to protect the environment and ourselves.

Generally speaking,there are three effective ways.

First of all,the government should take into serious consideration the emergency and severity of the air pollution,and take measure to deal with it.

Such as more public transportation systems should be put in use,more energy-saving resources should be utilized.

What’s more,every little effort from individuals counts.

The citizens should contribute to the reduction of pollution by driving less.

Last but not least,try to reduce the time of outdoor activities,especially when the air quality is not good enough.

From what has been mentioned above, to protect our air,we must keep in mind that whatever we give out,we take back in the long run.

So we have to drive less,pollute less and make more changes.

Today, we live in the modern world, most things we do can use the machine. The technology brings so many convenience to us, it facilitates our life. As we are facing the new products all the time, the traditional things are fading away. Take the paper-cut for example. When I was very small, paper-cut was so popular in my grandma’s generation, most women could cut all kinds of interesting shapes.

While today when I went back to my hometown, I found that most of them had stopped cutting papers, because they could buy them at the very low price.

What’s more, the young people don’t learn such art, for the parents think it is not necessary for their children to learn the old-fashion thing. The tradition should not be abandoned, it is the reflection of our culture. Even facing the challenge, we need to inherit the tradition.

今天,我们生活在摩登时代,我们可以使用机器做大部分的事情。科技给我们带来了很多方便,它便利了我们的生活。我们每天都面对着新产品,传统的东西正在慢慢消失。以剪纸为例。在我很小的时候,在我祖母的那一代,剪纸很受欢迎,大多数女性可以剪出各种有趣的形状。现在当我回到家乡时,我发现他们中的大多数已经停止剪纸,因为他们可以以很低的价格购买。更重要的是,年轻人不了解这种艺术, 以为父母认为他们的孩子没有必要去学习这种不时髦的东西。传统不应该被放弃,这是我们文化的反映。甚至面临挑战,我们仍然需要继承传统。

People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

My preference depends on the purpose of the travel. On a summer vacation I travel to refresh myself and to see the countryside. When I use my feet and walk on a grass covered path along a river or among the hills I feel detached from the noise of the city and closer to the nature. And when I travel on foot I get more freedom. I can plan my own schedule. I can choose my own route. I can stop where I like. And I can see things and people that I might miss if I travel on a train or on a bus. net

When faster and more convenient ways for travel are becoming available, I still favor using my own feet. I get much pleasure from it. People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

温室里的花朵永远都是最脆弱的,学会独立是很重要的。下面是小编为你整理的关于独立的高中英语作文,希望你喜欢! 关于独立的高中英语作文篇1

Today in China,many families have only one child.So the children usually doted upon by all family members.Gradually some of them get used to depending on their parents and lack the ability to solve problems independently.

There are some ways to help children to be independent.Firstly,the child should have a chance to see the world around him.He must understand that there are various competitions in this world,and everyone can find his right position in the society only by individual efforts.Secondly,the parents should give the child enough help to make him feel comfortable.Its impossible to ask a child not to depend on parents at once.A child needs help from the beginning.Without any help,the child may lose his faith.At last,parents should let his child make decisions,which can temper his ability to deal with problems.

No parents can accompany the children for the whole life.It is the child himself who is responsible for her own fate.Only an independent person can live and succeed in this world.

今日的中国,很多家庭都只有一个孩子.所以孩子往往成为全家人生活的焦点.有些孩子逐渐养成了依赖家长的习惯,从而导致他们缺乏自己解决问题的能力.

这里有几点可以帮助孩子变得独立.首先,孩子应当正式他周围的世界,每个人只有通过自己的努力才能在社会中找到他自己的位置.其次,家长应给予孩子足够的温暖让他感到舒适.不能要求每个孩子从不依赖父母.孩子需要一个起跑的平台.没有任何帮助,孩子或许会失去信念.最后,家长应让孩子做决定,如何依靠自己的能力解决问题.

没有父母可以陪伴孩子一辈子.决定自己的命运是孩子肩负的责任.只有独立的人才能在这个世界生活并取得成功. 关于独立的高中英语作文篇2

When I was very small, I was so envious about the adults, because they could do whatever they wanted and did not have to depend on their parents. For me, I did not have money and my parents limited my pocket money, so I couldn’t spend the money to buy whatever I wanted. It seems to me that being an adult is my only wish. Some day, I learned from the movie that being an adult was not that as perfect as I thought. In the movie, the man struggled to earn money to pay his bills, what’s more, he had to stay away from his family. Loneliness was always around him. To be independent means we can live our own way and make our own decision. We have more freedom. But at the same time, it also means more annoyance. So why just we enjoy this moment.

在我很小的时候,我很羡慕成年人,因为他们可以做任何他们想做的,不必依赖他们的父母。对我来说,我没有钱,我的父母限制我的零花钱,所以我无法花钱去买所有我想要的。似乎成为一个成年人是我唯一的愿望。有一天,我从这部电影中了解到,作为一个成年人也没有我想象中的那么完美。在电影中,那个人努力挣钱来支付他的账单,更重要的是,他不得不远离他的家人。寂寞总是是围绕着他。独立意味着我们可以有自己的方式生活,做自己的决定。我们有的自由。但与此同时,这也意味着的烦恼。所以为什么不享受这一刻呢。 关于独立的高中英语作文篇3

When we talk about being independent, we often think about leaving our parents and living alone. The mental independence is always ignored by people, mental independence means the person can measure the things and make the right decision. As for the children, even they move out and stay far away from their parents, but sometimes they just can’t control themselves, they will get the bad behavior, like smoking and drinking, their life is losing control. The young people need to cultivate their independent spirit, they should think by themselves, learn to take care of the other people, thus they can be the real independent. When a person grows up, they can be strong enough to support their lives and at the same time, they can be mature enough to make their own decision. They can tell what is wrong and what is right.

当我们谈到成为独立,总是想要离开父母,独自居住。精神上的独立总是被人们忽略,精神上的独立意味着一个人能衡量事情,做出正确的决定。对于孩子来说,虽然他们搬出去,远离父母,但是有时候他们无法自控,养成不好的习惯。比如抽烟和喝酒,他们的生活会失控。年轻人需要养成独立精神,他们应该自己思考,学着去照顾别人,这样才能真正的独立。当一个人成长了,他们才能够足够的强大去养活自己,同时,也能够足够成熟去做决定。他们能区分什么是好,什么是坏。

why is goal-setting important? because goals can help you do and experience every meaningful thing you hope for in life. instead of letting life happen to you, goals allow you to make your life happen.

successful people have visions of what their life should be and they set lots of goals, both sbort-term and long-range, to help them realize the visions. by setting goals you are taking control of your life. it is like having a map to show where you want to go. a driver with an aim arrives at the destination without any waste of time or wrong turns.

on the contrary, a driver with no aim drives aimlessly around, never getting anywhere and just using up gas and oil. winners in life set goals and follow through on them. they decide what they want and then get there by making plans and setting goals.

goals ara not difficult to set and they are not difficult to reach. it is up to you to find out what your goals, ideals and visions really are. with a clear direction, and with certain plans, you will straightly get what you want.

without a goal, you have to live a passive life. you do not know where to go, what you want and why you are listless. then your life be comes dull and meaningless just like the dead water in a muddy lake.

There is a saying that man proposes, goddisposes, which means man plan the things and the rest of the outcome lies inthe luck.

This saying reflects the connection between hard-work and luck, whichis though sometimes we have worked so hard, luck occupies great position, theunexpected things happen and refrain us from succeeding.

In order to besuccessful, people work so hard, they believe they can achieve their goals, butlacking luck stops them achieving their goals.

So working hard doesn’t meanbringing people success directly, they just need to try more times, withoutluck, they still can make their goals. Luck can help people close to success,without hard-work, they can’t be successful. Hard-work and luck make peoplerealize their goals, but without luck, people still can make it by trying moretimes.

有一句话说谋事在人,成事在天,意思是人们计划事情,剩下的结果依赖于运气。这句话反应了努力和运气之间的联系,那就是虽然有时候我们很努力工作,但是运气也占据了很重要的位置,意外的事情会发生,阻挡人们成功。为了取得成功,人们努力工作,他们相信能达到目标,但是运气的缺失让他们无法达到自己的目标。因此努力并不意味着能直接给人们带来成功,他们需要多试几次,没有运气,人们仍然可以达到目标。运气帮助人们接近成功,没有努力付出,无法成功。努力和运气能让人们实现目标,但是没有运气,人们多尝试几次,也能终将办到。

Air pollution is one of the major problems of the modern world.

A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too.

Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.

Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities.

They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material.

Also, engineers try to design and locate new power plants to do minimum damage to the environment.

However, it may be that we still have a long way to go before we have a "clean" world.

Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do.

People will continually find new ways to control pollution.

日记是用来叙述一天中发生的有意义事件的文体。

第一,注意日记的格式:一般是左上角写当天的日期,右上角写当天的天气情况(cloudy/clear/windy/rainy/fine/snowy…)。日期通常采用两种写法:一种是按“月、日、年”顺序;另一种是按“日、月、年”的顺序。注意要在年份之前有一个逗号,而且月份通常可用缩写词(如:Jan.,Feb.,Mar.等)。如果需要写星期,可将其写在日期的前面或后面。如:Monday,May15th,2008或May15th,2008,Monday

第二,抓准日记的时态:日记记叙的时间通常是在当天的下午或晚上,因此所用的时态多为过去时态。但应灵活掌握,如果日记叙述天气、描写景色或为了描写生动,也可用现在时。

第三,日记一般按事情发生的先后顺序记述,所以常需借助一些表示先后顺序的词语,如atfirst,then,lateron,afterwards,finally,atlast等。一定要注意句与句、段与段之间的连接和过渡,适当使用一些过渡词语使其连接紧凑、过渡自然。

第四,确立日记的中心要点,尽量突出主题,可以通过对某个细节、某个侧面的描写来突出主题,千万不要写成一个流水帐。

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 doesnt 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 dont take action to show respect to the environment.

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. 保护环境初三英语作文(二)

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. 保护环境初三英语作文(三)

Pollution has been a serious problem for a certain time around the world. There are many causes for it. Transportation is the main factor of pollution. When the waste gas from cars is released, the air is polluted. People breathing in the polluted air can develop respiratory disease. Another factor is that people throw their garbage everywhere. All kinds of garbage not only spoil the splendid environment, but also cause environmental pollution. Whats more, industrial pollution also deserves our attention. Wastewater from factories is poured into rivers and this causes water pollution. As a consequence, the greenhouse effect becomes a problem which needs our immediate caution and how to solve is urgent all over the world. At present, some measures have been taken to prevernt.

For example, people classify the garbage and some is recycled after being collected. People are also encouraged to use paper products instead of plastic products because we know that our living condition will be worse if we keep ignoring this problem. And I believe we can prevent pollution if everyone makes the efforts.

篇18:环境污染的原因

一:环境污染的根源

在十年前的中国,大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样,看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产,燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝,随着中国经济的迅速发展,人们生活水平的不断提高,人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题,其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬,专家们各有其立场,但对于普通百姓来说,全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖,海平面上升,冰川融化,动植物灭亡的问题,人们大多数是在电视新闻或报刊杂志上看到,恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题,人们开始关注更多的便是最近发生在北京,广州,武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康,更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象,国外专家学者很多年前便开始研究。

那么何为灰霾?灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物(PM2.5)和臭氧()、二氧化氮()、二氧化硫()、挥发性有机物()等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关,还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种,直径小于2.5微米的颗粒物(PM2.5)和直径小于10微米的颗粒物(PM10)。虽然两种形式的颗粒物都对人类健康有极大的危害,PM2.5被普遍认为是更危险的,因为它的体积小,大约只有人类头发宽度的1/30。人们在呼吸时,PM2.5可以进入人类肺组织深处,甚至进入血液,造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此,PM2.5可以传播的更远,停留在空气的时间越长,影响更大的人口。PM2.5和PM10的主要来源包括机动车,电厂和其他工业源,以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合,可以在城市或农村地区天空一片阴霾,而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因,像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围,当地空气干燥,白天阳光充足。到了晚上,地表面冷却很快。地面附近的空气变冷,而上层空气都比较热,形成逆温。北京市位于华北平原的西北边缘,背靠太行山余脉和燕山山脉,面对辽阔的华北平原,东南距渤海约150公里, 地处暖温带半湿润地区,气候属于暖温带半湿润大陆性季风气候,四季分明,春季多风和沙尘,夏季炎热多雨,秋季晴朗干燥,冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远,周围地形如盆地,集热容易散热难,河湖多、晚上水汽多,城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市,而且城市海拔较低,周围至少有一面是高地,都分布在低于南北纬50度的地方。这些地区夏季阳光明媚,天气温暖干燥。在城市的盆地地区,逆温现象十分普遍。夏季的阳光使地面温度升高,城市街道和建筑物迅速升温,与炎热的物体表面接触的空气温度升高。通过对流空气向上运动,但它却不能穿透逆温层,因为上面的空气温度更暖且密度更小。空气聚集,但连续的对流形成了垂直的循环,使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下,通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集,大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响,学者称它为街谷模型。随着城市化的加速,城市及城市周边的自然生态系统逐渐被人工生态系统取代,取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续,高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时,风速迅速降低并产生特殊的湍流,使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用,因此,对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市,尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物(PM)浓度和40%的二氧化氮(NO2)浓度。因此,通过对植被的合理利用能过创造一个有效的城市污染过滤膜,对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题,相反它是一个长久的问题,从它如何形成,加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象,它只是地球环境污染的一个缩影。我们更应该探究它的根源问题,什么才是它形成的根源,什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题,但我们可以通过减少排放源,通过增加植被,加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼,越来越发达便利的交通,相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了,人们是否会怀念那晴朗的蓝天,向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

二:环境污染

就最近这几年来看,随着各地区的经济迅猛发展,环境污染问题也越来越严重,保护环境,维持生态平衡也成为了我们每个公民应尽的责任和义务,也是为了社会更好发展的一项重要举措!

何为环境?从哲学的角度来看,所谓环境,主要指我们所研究的主体周围的一切情况和条件。对于人来说,环境是指人生活于其中,并能影响人的一切外部条件的综合。人的生活离不开好的环境,在人类几百万年的历史进程中,环境对开创人类文明和进步发挥着巨大作用。

大气资源、水资源、土地资源等等,都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质,创造出地球上高度的人类文明。但是,人类在开发利用环境资源的同时,也对自己的生存环境产生了一系列环境问题。

在我们身边就有很多污染环境的污染物,例如说:大量的生活废弃品,塑料袋(也称白色垃圾),一次性木筷,一次性饭盒,果皮纸屑。污染物对环境来说,毫无疑问,肯定有很大的危害,例如动物的腐烂的尸体会影响环境卫生,而且还会滋生细菌。饭店、餐馆认为很卫生的一次性木筷,使用后随便一扔,影响了市容,破坏了环境。。

现在像我们柳疃镇、青乡乡,最近电网部门纷纷撤除喷水机器的使用。喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。人类的活动会使大量的工业、农业和生活废弃物排入水中,使水受到污染。又例如说,我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡,地区农民上海捕鱼,鱼的体内含有大量化学物质对人们的身体健康造成了危害。据资料统计,目前,全世界每年约有4200多亿立方米的污水排入江河湖海,污染了5.5万亿立方米的淡水,这相当于全球径流总量的14%以上。1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义,即水体因某种物质的介入,而导致其化学、物理、生物或者放射性等方面特征的改变,从而影响水的有效利用,危害人体健康或者破坏生态环境,造成水质恶化的现象称为水污染。水的污染有两类:一类是自然污染;另一类是人为污染。当前对水体危害较大的是人为污染。水污染可根据污染杂质的不同而主要分为化学性污染、物理性污染和生物性污染三大类。

最近,我发现政府部门、昌邑环卫局开始大力整治环境,沿街排查污染源,青乡街也定点安置了便民垃圾桶,替代了原来垃圾围绕街道,臭气熏天的状况。各个村庄开始整治村内环境的污染源,使街道、村庄焕然一新!而这不是主要的,更重要的是我们每个人自觉保护环境,保护我们赖以生存的家园,为了我们更为了我们的后代,树立好榜样,奠基好基础,让我们的家园更加美丽、更加丰富多彩!

所以呢!环境与我们的生活密切相关,保护环境卫生从我做起,从现在做起:不随地吐痰;不乱扔垃圾;废弃电池和塑料袋要处理好;多植树造林,不践踏草坪;不污染水源。保护环境,我们有责!看你的行动喽!

小建议:家庭生活中的塑料瓶可以做成装饰品,可回收物品可以卖出,换来金钱买实用的东西岂不很好?一次性木筷消毒清洗一下可以做成装饰品,你也能开小店赚大钱了!化废物为贵宝,让自己的心情更舒畅,让自己的心灵更纯洁,让自己的家庭更温馨!

三:环境污染

在二十一世纪的今天,人类赖以生存的地球环境越来越恶劣,灾难频发,旱灾、洪涝灾害、土地沙漠化、地震、全球气温上升、海啸等等过去,以我所受到的信息宣传,简单以为环境污染只是浓烟滚滚,或者水面上漂浮着垃圾、发出恶臭,蚊虫成堆、尘土飞扬等等。但是,今年从网络、报纸、广播、电视、人们的关注里,我似乎明白;现实的情况要糟得多。西南五省大旱,就是我们自己想都没有想到的原因,专家分析:因为在过去10几年中,西南从新西兰大量引进桉树速生林,为了求短期的经济利益,毫无限制的大面积种植,以用来工业造纸,从而导致物种生态环境失衡,形成地下水严重缺失。俗话说,十年树木,百年树人,可这种桉树两三年就成材,是一种巨大的抽水机和抽肥机,不断侵蚀着其他植物物种的生存空间,而当地人却沉浸在多种树就可以保护环境的僵化错误的指导思想中,不断的在往恶性循环上发展,正是这个想到想不到的原因最终导致西南几百年的大旱灾。在报纸上,我看到温总理在一片干涸开裂的耕地上,捧着一颗枯死的禾苗,只说了一句话:“痛定思痛!”云南拥有大片的原始森林,风景名胜众多,地理环境独特,自古以来就是一个山清水秀,气候宜人的好地方,可是为了种植这种桉树,大量砍伐原始森林,想象这些经过几十年甚至数百年才形成的树木,仅仅是为了去满足最快速度的造纸而被破坏,真是让人可惜,并且痛心。据说旱灾的另一个原因,就是所有的大江小河都修起了水电站。对这一点我有自己的感受,早两年湘江的水面多么宽广,可是上游修了一个水电站后,下游的水明显减少,甚至连河床都经常露出来,同时影响到了城市自来水的引水工程,我都有这些感受,那些江河里小鱼虾们感受就应该更深了。前些天报纸上又爆出地沟油事件,报纸上说地沟油是别人吃完的饭菜倒进垃圾桶后,一些黑心商人把这些进行简单的提炼加工后,不但闻不出异味,加入香精后吃起来还挺香,但是对人体危害很大,我现在都不敢随便在外面吃东西了。环境污染的问题日益严重,影响到了我们生活的方方面面,对此我感到非常的忧虑。

四:河道为什么会污染

在我们学校旁边,有一条小河,听长辈们说,原来这里的河水清澈见底,河里鱼虾成群,夏天人们喜欢在水里游泳,还直接取水饮用呢!可如今,河水不但变得混浊,有时还有臭味呢!

为什么河水会发生翻天覆地的变化呢?经过我们全班同学的观察分析,河水污染有许多原因 。首先,人们不重视环保,乱倒垃圾。如有一次,我去张微家去玩,吃了一根香蕉,问她的妈妈:“阿姨,香蕉皮扔哪里?”只见她从我手中拿过香蕉皮,又随手用力一扔,扔进了小河,说:“这就是我们家的垃圾桶。”甚至有人把死猫死狗也扔进去了,这时,如果你从旁边经过,一阵阵臭味就会扑鼻而来。我真是不明白,人们为什么不多走几步把垃圾扔到垃圾箱里让垃圾车运走呢?。其次,人们家里的化粪池的排污口就直接通向小河。特别是我们学校,大小便没有经过处理就流进了小河,让人看了真是恶心。河水不变臭才怪呢!还有人们给庄稼喷了农药后,就在河里洗药筒等等。由于各种原因使河水变得越来越脏,甚至发臭,更不用说饮用,就连小鱼也快要无家可归了。

我想向人们呼吁:“水是生命的源泉,没有水就没有生命,就没有我们这个美丽可爱的家园,所以请你们不要再伤害小河了,难道你们就没有看见小河在哭泣吗?”

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿,而且因为缺水而干渴。对你来说这可能似乎奇怪:因为我们的地球表面75%由水覆盖着。但是,这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下,和其他来源的淡水供人们饮用、使用。即使如此,这3%的水源我们也不能够完全使用,因为有些淡水是以冰山或冰河的形式存在。更糟糕的是,一些水源已遭受了污染。

然而,尽管按现状看来,这些少量的淡水即使时常转化成雨水的形式,对我们来说,也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91,000升水,你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行,但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言,与空间站不相上下。
