城市环境变化英语作文（20篇）

Once man did not have to think about the protection of his environment。

There were few people on the earth， and natural resources seemed to be

unlimited。

Today things are different。 The world has bee too crowded。 We are using up

our natural resources，and polluting our environment with dangerous chemicals。 If

we continue to do this， human life on earth will not survive。

We realize that if too many fish are taken from the sea， there will soon be

none left。 Yet，with modern fishing methods， more and more fish are caught。We

know that if too many trees are cut down， forests will disappear。 Yet， we

continue to use powerful machines to cut down more and more trees。 We see that

if rivers are polluted with waste products， we will die。 Yet， waste products

are

still put into rivers。

We know that if the population continues to rise at the present rate， in a

few years， there wont be enough food。What can we do to solve these

problems?

If we eat more vegetables and less meat， there will be more food available。

Land for crops feeds five times more people than land where animals are

kept。

Our natural resources will last longer if we learn to recycie them。

The world population will not rise so quickly if people use modern methods

of birth control。

Finally， if we educate people to think about the problems we shall have a

better and cleaner planet in the future。

As time goes by, man is making the earth sick. People cut down too many trees and leave rubbish everywhere. Factories let out their waste without doing anything to it . This has caused some serious problems. Such as the land is sandy, the river is dirty, the air is less clean, even the temperature of the earth is rising. What should we do to save the earth ? My suggestion is that we should plant more trees, put rubbish into dusbins and stop factories (from)pouring waste directly into the air or rivers. In all, we have only one earth, we should do our best to protect it, or we will regret.

社会在进步，祖国在发展，但是我们的环境了，却变得越来越糟糕，下面以我们家乡环境的变化来看看我们的环境变成什么样子了。

有一天，我回到久违的家乡桐柏时，惊讶的叫了起来，以前，我一回来，第一眼看见的是那又大又高的山，山是那样的绿，漫山遍野都是绿色;那又长又宽的河，水是那样的清，一眼可以看到小鱼在河里畅游。可是现在，山上的树木不断减少，裸露的土地面积不断扩大。河底的沙子被挖土机挖出一个又一个的大洞，以前清澈见底的大河变成了垃圾堆，黑黑的、散发着阵阵的恶臭，几乎所有的小鱼都死了……

我想就算我们的祖国变得再富裕，社会变得再发达，环境破坏了一切也还是徒劳，让我们以我们家乡环境的变化为鉴，好好保护环境，好好保护我们的家园吧。

现在，地球环境持续恶化，给人们带来了许多灾难，这一切都来自人们的污染。想要让她减少污染，只有环保。

生活里，环保随处可见，比如：节约水资源，少用塑料袋，利用太阳能、水力发电。宣传环保的人也多了，有说地球在哭泣，请保护环境的;也有说保护环境，人人有责的，各种各样，五花八门。但也有人不爱惜地球，依旧我行我素：浪费纸张，浪费水资源，开汽车。

一次，我在街头看见一个人在抽烟，抽完后连烟头也不灭，直接扔在了地上。接着，他又开始吃瓜子，吃完的壳随便一吐。我实在看不下去，就对他说：“怎么能这样呢?”他说：“一个小孩子，懂什么呀，走开。我没有害怕，对他说：“我虽然小，但也知道这样不对，何况你大人!而且你还直接把烟头扔在地上，万一现在天气干燥，引起火灾怎么办。”停了停，说，“还有瓜子壳，人家看了怎么想啊，你这是在影响环境。”那人低下头，没有说话，我想他会改正的。

还有一次，我到堂弟家做客，看见他洗手时把水开得很大，洗完手后他还用很多纸擦手。我看了后对他说：“你怎么这么浪费呀?”他听后，撅着嘴对我说：“就这么一点，又没什么关系!”我生气地说：“这怎么会没关系呢?你知不知道那些贫困山区的孩子们一天只喝多少水?知不知道他们只有多少纸?”可我那不服输的堂弟却理直气壮地说：“不知道!”我叹了口气说：“我们比他们要幸福多了，你怎么不知道知足呢?”这时，堂弟知道了事情的“重要性”，低着头说：“我知道错了，我会改正的。”

让我们从我做起，保护我们唯一的大家园吧!

A few days ago, I saw lots of uncle aunt spitting in the street.

Not, today again see a school wearing a black T-shirt uncle, he casually spit onto the ground. I quickly come forward to stop, I didnt think uncle didnt look at me, continue to go forward.

Sometimes, the grandpa in the home also can make the same mistake. Driving well, suddenly to a screeching halt, opened the window one mouthful phlegm vomit. When I stop him, he said: "it doesnt matter." But Im not discouraged, see uncle, aunt spit anywhere, I will stop them in time. Remind them to pay attention next time. If they had followed my advice, my in the mind is better than eating the honey still sweet. For example, the last time I go to the park to play, my father and mother saw a aunt walked into the grass, vomitted an one mouthful phlegm. I saw hurriedly block, aunt smiled at me and said "Im sorry, but I will pay attention next time." At that time, dont mention how much I have a sense of achievement.

Whenever grandpa didnt listen to my advice, I would reason with him.

Grandpa heard my these words have never spit sputum. Mistakes can change or good comrade!

For one hundred days after the youth Olympic Games, let us work together, starts from me, do civilization from nanjing, nanjing and beauty.

前几天，我看到了由很多叔叔阿姨在马路上随地吐痰。

这不，今天放学又看到了一位穿着黑T恤的叔叔，他很随意地把痰吐到了地上。我急忙上前阻止，没想到叔叔看都没看我一眼，继续往前走。

有时，家里的爷爷也会犯同样的错误。开车开得好好的，突然来个急刹车，打开车窗吐一口痰。我阻止他时，他却说：“没关系的。”但我并没有气馁，看到有叔叔，阿姨随地乱吐痰，我就会及时阻止他们。提醒他们下次注意。如果他们采纳了我的建议，我的心里会比吃了蜜还甜。例如，上次我和爸爸妈妈去公园玩，看见一位阿姨走进了草丛，吐了一口痰。我看了连忙阻止，阿姨友好地冲我笑了一下，说“不好意思，我下次会注意的。”那时，别提我多有成就感了。

每当爷爷不听我劝告的时候，我就会跟他讲道理。“吐痰容易传染流行性感冒，肺结核等疾病，危害很大，这样做不但自己不文明，还害了其他人，对我们的环境也会造成很大的破坏。”爷爷听了我的这一番话就再也没有随地吐过痰。知错能改还是好同志嘛!

为了一百天以后的青奥会，让我们大家同心协力，从我做起，做文明南京人，创美丽南京城。

一转眼间十年过去了，我已经20岁了，再来看看我的家乡大连。大连是个海滨城市，所有我们先来看一看大海。海上的漂浮物不断的减少，浅水里的小鱼不断地增多，我相信大连的海这样发展下去会更好。大连的天空湛蓝深远，空气清新甜润。再来看看早市。早市的变化就更大了，大家不仅早早的就把摊位摆好了，而且一点吵闹声都没有，再也没有商贩在称上做手脚赚那黑心钱，没有顾客再想多拿多占了。也没用无辜的小动物以为垃圾污染而变异了。

Once man did not have to think about the protection of his environment。 There were few people on the earth， and natural resources seemed to be unlimited。Today things are different。 The world has bee too crowded。 We are using up our natural resources，and polluting our environment with dangerous chemicals。 If we continue to do this， human life on earth will not survive。 We realize that if too many fish are taken from the sea， there will soon be none left。 Yet，with modern fishing methods， more and more fish are caught。We know that if too many trees are cut down， forests will disappear。 Yet， we continue to use powerful machines to cut down more and more trees。 We see that if rivers are polluted with waste products， we will die。 Yet， waste products are still put into rivers。

过去，人们不必担心保护环境的问题。因为那时地球上人口稀少，自然资源似乎取之不尽。如今，一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源，有毒化学制品的使用也正污染着环境。如果我们继续这样下去，地球上的生命将不复存在。我们都明白如果从海里捕捉太多的鱼，海里就不会再有鱼了。可是，现代化的捕鱼技术使得捕鱼量越来越大。我们都明白如果砍伐太多的树木，森林就会消失。可是，我们仍旧使用强大的机械砍伐越来越多的树木。我们都明白如果河水被废弃物污染的话，我们仅有死路一条。可是废弃物仍然源源不断地进入河里。

We know that if the population continues to rise at the present rate， in a few years， there won＇t be enough food。What can we do to solve these problems?If we eat more vegetables and less meat， there will be more food available。 Land for crops feeds five times more people than land where animals are kept。Our natural resources will last longer if we learn to recycie them。The world population will not rise so quickly if people use modern methods of birth control。

我们明白，人口继续照此刻这个速度增长的话，不出几年，就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜，少吃肉类的话，我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话，自然资源就能持续更久。如果人们使用现代化的生育控制方法，世界人口就不会增长如此迅猛。

Finally， if we educate people to think about the problems we shall have a better and cleaner planet in the future。

最终，如果我们能够教育人们都意识到这些问题的话，未来我们就会有一个更好、更洁净的星球。

Environmental problems are becoming more and more serious all over the world.For example,cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories.Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore,wherever we go today,we can find rubbish carelessly disposed.Pollution is,in fact,threatening our existence.

The earth is our home and we have the duty to take care of it for ourselves and for our later generations.Fortunately,more and more people have realized these problems.Measures have been taken to cope with these problems by the government.Laws have been passed to stop pollution.I hope the problem will be solved in the near future and our home will become better and better.

全世界的环境问题变得越来越严重.例如汽车污染的空气影响了人们的呼吸,工厂释放污染的气体,山上的树木被砍伐,污水不断被排人河里.另外,无论我们走到哪里,到处可见随意丢弃的垃圾.事实上,污染正威胁我们的生存.

地球是我们的家园,我们有责任为我们自己和我们的后代去照顾好它.庆幸的是,愈来愈多的人们已经意识到这些问题.政府已经采取了很多措施去解决这些问题,法律已被通过以制止污染.我希望这些问题在不远的将来能得到解决,我们的家园变得越来越好.

时间过得真快呀，人们说的真对呀：“光阴似箭，日月如梭”[U1]，一转眼二十年过去了!在一次朋友聚会上，我们聊了聊自己的家乡，突然我想起了自己的家乡，二十年过回去了，不知道家乡怎么要了，我立刻坐公交车到火车站，买了一张火车票，就马上收拾东西准备回家乡

到了家乡，我大吃一惊[U2]，一看，原来房子旁边的庄稼，都成了高楼大厦、酒店、药店，我到了我家，一看我家怎么变了，这是不是我家呀，别在走错了，过了一会，过来一个人，我就问，这个是谁家，我一听，还真是我家，原来的旧房子，都变成新的了，没想到变化这么大。我一进家，发现我的在家的时候种了一棵石榴树，没了，我还在离开家乡的前一天的晚上，睡不着，就出来，在这刻石榴树下挖了一个大坑，把我珍藏很久的几十个一分钱埋到了石榴树下面。可是那棵石榴树已经没了，不知道那十几个一分钱还有没有，找了半天都没找到。

我又问妈妈，我的那只小乌龟还有没有，我一看我养的那一只小乌龟，不再是小乌龟了，成大乌龟了，比原来打了很多。

这二十年家乡的变化可真大呀，我都人不出自己的家在哪了!

living in a city has both advantages and disadvantages. it is often easier to find work. there are always many choices of public transport. besides, there are a lot of interesting things to do and places to see. you can eat in good restaurants, visit museums, go to cinemas and go to parks whenever you want to relax. however, living in a city is often very expensive. you must find a well-paid job, otherwise, you will not be able to afford the things you will do. whats more, the city is always crowded, noisy and dirty. it is very difficult to find a good place where people can enjoy peace and fresh air as in the countryside.

Great changes have taken place in my hometown for recent years.big department stores and factories are everywhere. Different kinds of cars and buses are running in the big streets.with the development of the society，The life of the us is greatly improved.

I used to live in a small house and small houese surround the whole city. the qaulity of our life is very low,people were always worried that they would have no money for using or they can not get what they like. we could seldom see any foreign tourists.

But now, with the support of the government . My hometown has developed quickly and has changed a lot.people are living in a rich and high quality society,almost each person has a car,the transportation is convinient,meanwhile. more and more high buildings are being built which brings our hometown a new look. many wonderful places have been opened up that attracts many tourists.

Also,the people in my hometown are getting busier, everywhere you can see peoples footprints.

This summer vacation, I joined a social practice to be a part-time tourguide. There I found something that impressed me a lot.

People who love traveling are always finding places to take a vacation, which caused a lot of troubles.For example, I found that some people were used to dropping out the trash everywhere. They just regarded the sightseeings as their houses, which cost a lot to clean it up. Besides, some one should write down their names on the trees and walls. People who wanted to leave their names whereever they went are always to punish in future.

Nevertheless, I also found some good examples, such as teaching tourists not to destroy the places of historic interests, helping clean up the environment,etc..I think we all need to teach more people not to hurt our precious nature. What we really need to do is protect them form destroying.

“上有天堂，下有苏杭”这是人们经常听到的，意思是：人们认为天堂是最美的，但是陆地上也有像天堂一样美的地方，就是苏州和杭州了！

莲花岛是一个著名的岛，如果要吃大闸蟹，就可以坐快艇来到店里，坐在快艇里非常刺激，在转弯时就像要翻了似的。最有趣的是外面的浪花达到窗户上，仿佛打在你的身上。到岸上，可以看到一家挨着一家的餐厅，餐厅里食物的香味芬芳扑鼻，真是让人闻了就想吃。

苏州还有很多风景优美的地方。列入世界文化遗产的拙政园，有假山奇多的狮子林，有微倾的虎丘塔，壮观的古城门。唐代诗人张继的《枫桥夜泊》诗，“姑苏城外寒山寺，夜半钟声到客船。”吸引了中外游客都要来枫林聆听寒山寺的钟声；祈求幸福！

听了我的介绍。你是不是也想到苏州游览一下呢？

Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers.

Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.

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.

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?

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.

以前的西塘，景色优美，风光宜人，塘水清澈见底，小鱼儿在水中漫步，野鸭们和各种不知名的小精灵在水上戏耍，塘边垂柳婀娜多姿，花儿争奇斗艳……可后来西塘却变了。

西塘变成了“垃圾场”。塘面上漂着许多垃圾袋，有时还漂着臭南瓜。水面下全都是黑黑的泥和人们丢的果皮。怎样才能让西塘不受污染呢?

从现在开始，我们要清理塘底的污泥，不让塘水流进西塘里，我们要塘边放一些垃圾桶，还要立一些告示牌，告诉塘边商店的老板和过往的行人不要乱丢垃圾了。

让我们行动起来，加入保护西塘的环境的行列中去吧!我相信不久的将来，西塘一定能像以前那样美的。

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.
