全文共 1331 字

+ 加入清单

环境污染(environment pollution)是指人类直接或间接地向环境排放超过其自净能力的物质或能量,从而使环境的质量降低,对人类的生存与发展、生态系统和财产造成不利影响的现象。具体包括:水污染、大气污染、噪声污染、放射性污染等。

人类生产活动对自然环境的污染主要包括两个方面:一是工业生产过程中产生的废水废气废渣和农业上使用的农药、化肥等对水、大气、土壤、食品的污染;二是在自然资源开发和利用中,产生的对环境的污染。

相信大家对于环保都有一定的认识,也曾读过关于限塑令,节约用水保护环境等为主题的作文。我们来看一下这篇范文,试着找出其中的优点与不足。

Where is my home?

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!

Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.

Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.

Environmental Pollution

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial

production and increased consumption of goods. Bedsides, the use of chemical substances

in agriculture also causes environmental pollution.Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

环境污染

最近我读了一则消息说在日本,许多商人向顾客出售新鲜空气,现在这种情况越演越烈。为什么呢? 因为在日本新鲜空气越来越少,在美国也是如此。

事实上,环境污染是整个世界正在面临的一个严重问题。这主要是由于人造物质,工业生产过程中所产生的废料以及消费商品的增长造成的。另外,在农业中使用化学物品也造成了环境污染。看看天空,你可以看到浓烟从高大的烟囱中释放出来,这些脏而有毒的物质流入我们赖以饮水的河流,数百万吨废物正堆积在我们周围。 中国大学排名

怎样改变这种状况呢?越来越多的国家正在试图拟定出一些有效措施控制环境污染,但至今成效不大。

reduce the dependence on cars. In short, our humans should take responsibilities

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.

空气污染不管是对我们还是对植物危害都很大,为什么这么说?这是我通过一次研究发现的,至于是什么研究,就听我慢慢跟大家说。

在庭园里种些花草,不仅能美化我们的家,还能净化我们四周的空气,让我们呼吸的空气更清新。因此有人说,一个具有一定规模的庭园就像一个不停工作的天然“氧吧”,能提供我们所需的清新空气。但近几天我发现我家的天然“氧吧”“罢工”了,每天清早我到院子里,再也呼吸不到以前那种清新的空气了。这是怎么回事呢?是什么令到我家的天然“氧吧”停止工作呢?我下定决心,一定要把那个“凶手”揪出来!

针对上述事件,我查阅了大量资料,综合我对花草、树叶的连日观察,发现嫌疑最大的是近日车辆的频繁来往,造成了严重的空气污染,加上附近的一些食店排放出来的油烟因近日风势不强,得不到有效的散解,被花草、树叶过量地吸收,造成叶片表面气孔被尘粒堵塞,以至它们不能“工作”。我咨询了自然老师,老师认为这种可能性很高,让我回家去试验一下。于是我回去采了一些花草样本,把它们栽在室内,定期让它们照射阳光,浇水次数加密,几天后,和其他的比较一下,发现经我“悉心照顾”的那些花草比外面的生长得好多了。根据我的实验结果,我把每天浇水的次数加密到每天3次,经过我一个多星期“苦心经营”,“天然氧吧”终于又恢复了正常的工作,每天为我们提供着清新的空气。

综合以上所述,我得出了结论:“天然氧吧”的停止工作,是因为周围空气污染的日趋严重,使花草过量地吸收了空气中的一氧化碳、碳氢化合物、氮氧化物以及空气中的悬浮粒子,以至花草、树叶中用于进行光合作用的气孔被堵塞,机能超荷,停止工作。我终于把这个“凶手”揪了出来!

你看,这就是空气污染的危害。空气污染其实伤害的不仅仅是我们自己,也伤害了地球上的许许多多的生物,还有我们的地球母亲……让我们一起行动起来,减少空气污染,一起保护我们的生存环境吧!

今天早上,我一觉醒来,发现天空是湛蓝的,是那种温柔的澜,纯洁的蓝。蓝的让人陶醉,让人心旷神怡。

今天的天这样蓝,是因为经过了暴风雨的清洁,否则它还会是灰蒙蒙的。为什么会这样呢?爸爸妈妈小时侯,天还是蓝蓝的。这一切的幕后凶手就是——环境污染

工厂在工作时产生的废气都是没有经过处理就直接排向蓝天,企业燃用汽油产生的废气也弥散在空中。同时随着经济的发展和人口增多,能源消耗量增加,产生的废气也是原来的许多倍。汽车、摩托车等机动车数量迅速增加,尾气排放量加大。这些废气中含有大量二氧化碳和烟尘。由此造成严重的环境污染。而环境污染又会造成大气层污染,大气层污染导致天空变灰。

空气污染的害处不单单只是天空变灰,有时还会有生命危险。

1984年12月3日凌晨,震惊世界的印度博帕尔公害事件发生。午夜,坐落在博帕尔市郊的一所杀虫剂厂——一座储存四十五吨化学有害物质的杀虫剂厂的保安闸出现毒气泄漏事故。

不一会儿就有毒烟雾袭向这个城市。形成了一个方圆25英里的毒雾笼罩区。先是近邻的两个小镇上,有数百人在睡梦中死亡;接着是火车站里的一些乞丐死亡。毒雾大幅度的扩散时,居民们惊慌失措,有的以为是“原子弹爆炸”,有的以为是“地震发生”,有的以为是“世界末日的来临”。一周后,有2500人死于这场污染事故,另有1000多人危在旦夕,3000多人病入膏肓。有15万人因受污染危害而进入医院就诊,事故发生4天后,受害的病人还以每分钟一人的速度增加。这次事故还使20多万人双目失明。

可见,空气污染的危害有多么大!为了缓解空气污染,请大家从身边的小事做起,不要在野外烧火,尽量不要用尾气排放量太高的汽车……相信有了大家的支持,空气污染造成的危害一定会消失!!!

英语作文汽车环境污染二

Too many cars have caused a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol. 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 buy private cars. Thus, the total number of cars in big cities will reduce greatly. On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.
