[保护环境英语优秀作文

一个星期六的早上，我去吃早点。在路上，我闻到了一股像狐臭一样难闻的气味，使我一阵恶心，仔细一看，原来路边有一大堆枇杷皮、枇杷核，这难闻的气味正是它腐烂散发出的。刚好有一位年轻的小伙子拿着一畚箕垃圾向这儿走来，只见他手一扬，“哗——”一大堆生活垃圾就倒在这儿了，我连忙向前去对他说：“叔叔，你不能这样做，这些东西烂起来很臭，这样做对大家的身体不好的，会使人生病的。”那位叔叔竟毫不在意地说：“大家都这样做，谁生病谁去看医生去。”

眼前此景使我想起了另外一幕：我们村子中间有一条溪流穿过，溪上建有两座桥，在我七、八岁时我记得桥下水流、风景十分美，是我夏天洗澡的好地方。不知是谁第一次带了头，把垃圾从桥边倒下，以后，经常有人效仿，于是，桥下垃圾越积越多，简直像一座小山一样，菜叶、果皮、死鸭、死鸡……腐烂之后，不仅蚊蝇乱飞，走在桥上，其臭难闻，大家意见纷纷。后来，虽然村民在村委的带领下，清理了几次，但现在总还是有人倒，溪水已显微白色，塑料袋漂浮在上面，灰絮状的脏物盖满了溪石，现在夏天我们要找一个洗澡的地方都要走到离村子老远的地方。

“以前我们家里用水自家挖个井就可以了，可现在村子里绝大多数地方打出的井水有发白的，发黄的，发黑的，发臭的，已不能拿来吃了，新区里的许多人家现在已经不得不买水吃了。”

“现在村里生病的人多，而且有不少人生的是比较严重的毛病，这和我们周围的垃圾乱倒、厂里废水乱排是有一定关系的。”

时常听到有大人这样说。

我从书本上了解到，农村垃圾的危害主要有占用士地，损伤地表；污染土壤、水体、大气；危害健康。大人们常说“身体是本钱”，可他们为什么还会这样做呢？长此以往，是不是会影响大家平安的生活呢？

同学们，我们是明天社会的主人，改善环境，营造平安的生活环境，也是我们的责任和义务。

平安在我们手中，多参加环保活动，多植树，多种花，使我们永远生活在拥有蓝天、碧水、绿地的美丽家园。

平安在我们心中，用心劝说自己的亲人、长辈处理好垃圾，为建设我们平安家乡做出我们少先队员的努力。

We all know it is becoming more and more important to protect our environment well.We should stop cutting down trees ,dropping litter everywhere and throwing waste before it is processed. It has caused lots of problems such as much rich land becomes desert;Rivers become dirty ;The air is becoming worse and worse ;The temperature is becoming hotter and hotter.So we must do something to change the situation.Wed better walk or ride bikes to work or go to school instead of driving a car,We mustnt use plastic bags.Our government must take some measures to prevent factories producing smoking etc.

How to protect/save our environment/world?

The environmental pollution is worse and worse /more and more seriously today. Water is polluted; we have no clean water to drink. Many trees are cutting down, some animals is getting less and less. Some factories are pouring dirty air in the sky, the population is increasing faster and faster, resources are getting less and less…etc. Not only does it affect our lives and health, it but also has a great affection in the future. Peoples health has been greatly affected by air, noise and water pollution. Many people died of diseases. In order to live a better life, we need protect our world。

We shouldnt throw away rubbish everywhere. We want to recycle, reduce, reuse things .Dont waste things. This saves money and reduces pollution. Use things for as long as possible. We dont use plastic bags. We must plant more trees and stop the people cutting them .We hope our world becomes more and more beautiful。

Today, people count on the high-tech products so much, we can see no matter

where we are, we could find people low down their hands, playing their

cellphones. About two years ago, it is very popular that people shopping online,

now as the function of cellphone has been highly developed, people can use their

cellphone to shop online. As shopping online is so convenient, more and more

people like to buy things online, especially the men, because they don’t like to

go out, now the Internet can help them shop in a quick way. The things online

are various, people can search what they want and compare with the price, they

can buy the products they want. Shopping online is the new way for people to

purchase, in the future, it will be more and more popular. The Internet provides

people’s life.

Although the world develops much faster and better, the resources on the earth get fewer and fewer.In order to protect them,something must be done.尽管世界发展得更快、更好，地球上的资源越来越少。为了保护他们，必须做些什么。

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.节约用水。水是生命之源。没有水，就没有生命。所以这是非常重要的我们这么做。我们不仅要保护饮用水和停止污染，而且充分利用它。

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working.节约用电。这是至关重要的。我们无法想象的生活就会像没有它。每个人都应该尽自己的最大努力节约用电。不要忘记关灯或其他当我们完成工作的电机。

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.拯救森林。他们是有用的。请停止切割下来，用再生纸代替。使我们的世界成为一个绿色的生活。

Recycle useful rubbish. Plenty of rubbish can be recycled like cans,paper, bottles, and so on. We can save resources in this way.回收有用的垃圾。大量的垃圾可以回收罐，纸，瓶，等。我们以这种方式可以节省资源。

世界之大无奇不有，这句话是用来形容我们的地球母亲很大方，人们认为它的身上有取之不尽用之不竭的能源，但是我们人类错了。比如说地下的煤矿。金。银。锡。铅等这些东西，都不是上天赐给我们的，而是地球母亲身上从远古时代，到现在的这么长时间掩埋在地下的花花草草长时间在地下形成的。所以我们要珍惜这些资源！

但还是有些人，为了利益还在乱开采它们把它们制造成杀伤力极大的化学武器！更把这些武器用在战争上，更破坏了大自然！

比如现在的毒气弹。闪光弹。烟雾弹。打仗时虽然不太用，但是用起来破坏力非常大！那就更不用说了，对植物破坏也有一定的影响！而且这样整天打打杀杀，双方都占不了便宜。

还有一些工人工作的地方，化学厂研究失败的污水，对每种生物都不好，把污水排的小河里，长江里，那样生活在水里的小鱼小虾也遭到了破坏，对我们自己也不利！

还有一些农民伯伯从农药店买回来的除草剂呀，除虫挤呀，利长剂呀等等都是化学物资产品！最少就不要用只要用了不仅费钱，对于那些在菜地里抓害虫的益虫也是一种危害，还有现在已经有沙漠移动这种以前很罕见的现象了，所以我们要多种树，还有一部分人没有注意到危险，仍然在滥砍滥伐！使沙漠移动速度加快了！

所以我们要从现在开始，要尽力保护环境，从小事做起不仅自己要保护环境还要发动身边的人去保护地球母亲现在的美貌！

环境保护是一个全人类都在面对的艰巨的问题，我来给家乡发展提十条建议。

第一条：少用一次性筷子。一次性筷子如果用得过多，森林的面积就会减少。

第二条：提倡垃圾分类。垃圾分类也能减少环境恶化，垃圾主要分为“可回收垃圾”、“不可回收垃圾”、“其他垃圾”等。

第三条：合理用纸，打印纸张时要双面打印，不能浪费纸张，应该节约用纸。

第四条：不乱丢垃圾。垃圾不能随地乱丢，应及时放进垃圾桶内。

第五条：节约粮食，粮食都是农民伯伯辛辛苦苦种的，要考虑有些地方的人还在挨饿。

第六条：少做私家车。可以多骑环保又能健身的自行车，也可以坐公交车，这样能减少空气污染。

第七条：少用塑料袋，据了解塑料袋是无法分解的。据了解，分解一个塑料瓶需要至少450年！

第八条：政府对工厂排出的废烟、废气、废水等都要采取有效措施。那些不仅会污染环境，还会影响人类的健康。

第九条：少用农药，被农药污染的水是对我们的身体是有危害的，会污染环境。

第十条：少制造噪音。噪音也是有危害的。

第十一条：节约用电。冰箱等电器也会造成环境危害，我们应该养成随手关灯的习惯。

让我们一起爱护地球吧，让我们的家乡发展得更好！

Protection of the Environment

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 become 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.

With the development of technology, today, our life is facilitated with all

kinds information sources. We can read books on the Internet, which is much

convenient than buying the books in the stores. I like to read E-books, because

there are many advantages. First, I can save a lot of money. Downloading the

E-books is for free, I can find all kinds of free sources. It is good for

students because they can save the money. Second, I can save a lot of time. Some

books are not easy to be found in the bookstore, sometimes I need to go to

several shops. But if I search the Internet, then the information is in front of

me. How fast it is.

As a student, it is my duty to go over my lesson after class, or I will

miss the important point. Many students choose to study in the classroom or go

to the library, as for me, I am in favor of the latter choice. I like to go to

the library. On the one hand, it is quiet. A lot of students just sit in their

places and wont make big noise, which provides an enjoyable environment for

students to study. On the other hand, I can consult many reference books if I

need. The library provides us all kinds of books. We can find help when we have

questions. I find much joy in the library.

What do you usually do in your spare time to relax yourself? Let me tell

you some ways to.First of all, you can stay in bed for a while, sleeping makes

people feel good.Secondly, you can join your friends in some fun parties, talks

with friends will let you feel comfortable.Thirdly, you can go outing alone. You

can either breathe new fresh air in the mountains or you can take a look at how

beautiful the nature looks like.Fourth, why dont you just play sports with your

family? Youll feel tired if you do too much exercise once, but it keeps you

healthy and energetic.Whats your opinion?

几年前，这条河又绿又清，看上去非常可爱。这也许无法与风景区所管理的景观相媲美，但却是培育。当我早晨走到那里，太阳透过我旁边的樟树照在我的脸上。微风徐徐吹来。它太温和了，受不了水的涟漪，但它令人耳目一新。那时，早餐的味道从远处传来。饥肠辘辘的人被烟和火所诱惑，但他的头仍在清凉的水和樟脑里。放学回家的路上，太阳更暖和了。河水闪闪发光。靠在岸边的篱笆上，我总觉得太阳正直射河里。我应该吓跑很多鱼。否则，就不会有这样的金光。虽然是一天，但有些猴子担心去钓月亮。樟脑似乎比较安静。下午可能被烈日晒得很难受，但这并不能阻止我偷取银行里的凉水。这一刻的安宁，不是饥饿，也不是夏天的酷暑所扰，也不是校园和家庭所扰。在树荫下，放松是件好事。

有时候下雨的时候，不应该在树下撑伞，但是孩子们的记忆力不太好，或者他们在校园里有流行的新事物，所以他们不在乎这样的小事。但雨中一定有一两件有趣的小东西，会让人失去很多乐趣。其中一只是河里的小螃蟹。有时它们会上岸，让人们高兴地抓住它们。我幸运地捉了好几次螃蟹。它们没有菜市场里的那么大，也不干净。我总是乐于把螃蟹扔回河里，杀死它们的辛勤劳动。这样戏弄他们很有趣。现在想想，我还是忘了螃蟹的味道。河蟹的寿命不长。荀子曾经用过“蚯蚓无爪无齿，筋骨有力”和“六跪蟹两把钳子”，据说学习不干，需要努力。然而，河蟹只有几周的寿命，成年蟹会蜕出几十个壳，蟹的生活很艰难，这是不干燥的。蚯蚓的寿命也比人类短，生长过程也很艰难。比如荀子说，经过一切努力，蚯蚓不仅是有生命的生物，而且是有生命价值的。这样一来，荀子的话就没有错了。真的不值得担心学习和寿命之间的关系。否则，我们怎么能说“学不成”。这样的怀疑和突然进入我的精神世界的过程，和雨水进入河流的过程，是一样的。

几年后，很少有人关心这条河。路边随意停放的汽车排起了长队，也堵住了雨天废气和积水时路过的尴尬。然而，没有人愿意接近那股恶臭的河水。我不再每天经过那个地方，但我常常感到抱歉。有一次我碰巧路过，看到离海岸不远的一艘渔船。有一个驼背的白发老人。他又瘦又弱，但力气似乎不小。在阳光下，他升起的泥土的味道弥漫着。相比之下，老人皮肤上的皱纹酱油颜色要干净得多。中途转学的我，没有亲眼目睹这条河的惨剧，只是一时心寒。天空依然蔚蓝，太阳依然照耀。应该是同样美丽的夏天，但是河水不再清澈，樟脑的味道也被掩盖了。至于那些小美女，她们已经成为过去，就像我长大了一样。很多事情之后，他们又增添了许多不愉快的麻烦。

我们怎样才能把这条河清理干净，使一切看起来像以前一样。

The earth is our home, but also our mother. Earth free supply us all kinds of resources, but we still for a little petty profit, regardless of the consequences of wanton to destroy her. As the only one earth, "the article said, we cant count on destroyed the earth moving to other planets, the earth if lost, then fell to the earths fate will eventually befall humans. So we too late, too late, to protect our earth, care for the environment, I suggest you to do the following:

1. Cherish now every mouthful of air, as far as possible to reduce the number of the factory, industrial waste gas will be less. The good news is, we see the government has put many polluting factories, rectification within a time limit or migration. We also know that every household use of coal gas has been changed to natural gas, advocating walking with less cars, this is to protect the atmosphere. We more afforestation, forest not only can breathe fresh air, also can purify the air. To stop deforestation behavior, less destruction of nature.

2. Dont abuse of various resources, such as coal, ore, wood, water... If these resources are endless, is bound to form all kinds of resources depletion, when people do not have the resources, we could not survive.

3. The water is the source of life, but it is too small. Although the surface looks large area on earth is covered by water, but with less than one over ten, an acute shortage of water in many cities, so, we should save water. At present, the school advocates our toilet cistern in home put a mineral water bottle, isnt it the measures to save water? Use to wash the dishes, the water that clean out rice water the flowers, use wash clothes water to flush the toilet, isnt it a to save water!

As long as everyone to do the above, the earth has been already saved!

地球是我们的家，同时也是我们的母亲。地球无偿的供给我们各种资源，而我们却还为了一点蝇头小利，不顾后果的肆意去破坏她。正如《只有一个地球》那篇文章所说的，我们不能再指望破坏了地球移居到别的星球上去，地球如果灭亡了，那么降临到地球上的命运终究也会降临到人类身上。所以我们亡羊补牢，为时不晚，保护我们的地球，爱护环境，我建议大家做到如下几点：

1.珍惜现在的每一口空气，把工厂的数量尽可能的减少，工业废气也会随之减少。可喜的是，我们看到政府已将许多重污染的工厂叫停，限期整改或迁移。我们还知道每家每户用的煤气已改成了天然气，倡导步行少用汽车，这都是保护大气的举措。我们还要多植树造林，森林不仅能呼出新鲜空气，还能净化空气。要制止乱砍伐森林的行为，要少破坏大自然。

2.不要滥用各种资源，如，煤、矿、木、水……如果这些资源被无止境的开采，必定会形成各种资源的枯竭，当人们没有资源时，我们就无法生存了。

3.水是生命的源泉，但是它又实在太少了。虽然表面看起来地球上大面积都被水覆盖，可是能用的却不到十分之一，许多城市严重缺水，所以，我们要节约用水。目前，学校倡导我们在家里的马桶水箱里放一个矿泉水瓶子，不正是节约用水的举措吗?用洗菜、淘米的水浇花，用洗衣服的水冲马桶，不正是为节约用水尽一份力嘛!

只要大家做到以上几点，地球就有救了!

My name is Beth. Im 14 years old, and I study in No. 1 Middle School of

Hangzhou. My school is very big and beautiful. Im very happy in the school.

I usually get up at 6:15 in the morning. Then I do morning exercises in the

playground. At 6:40, I have my breakfast. You can see many students and teachers

in the dinning room. After breakfast, I often read English with my

classmates.

We have six classes every day. The first class begins at 7:50 am. I like

all the classes for my teachers can make the classes lively and interesting. My

favorite subject is English, so I join English Corner every week. I can speak

English with many other students there. Its very interesting and exciting. I

think its helpful for me to learn English well. After class, I always play

games with my friends. We play soccer ball,basketball, volleyball, ping-pong and

so on. They are very relaxing.

I like my lessons, my friends and my teachers. In a word, I love my school.

I find my school life more and more meaningful and colorful. My school life is

wonderful, isnt it?

In China, the subjects that students learnt are necessary. They can learn special classes when they enter university. Sometimes I think it will be perfect to have the special class in middle school. On the one hand, students can learn more things besides the necessary subjects. They can develop more practical skills. On the other hand, students can cultivate their interest by learning something different. Though it is a little hard to open special classes, because education pays attention to scores, I believe that someday more special classes will be open, as the class reform calls on people to pay attention to the development of student mind.

在中国，学生所学习的科目都是有必要的。当他们进入大学以后，他们可以学习特色课程。有时我觉得在初中开设特色课程是非常好的。一方面，学生除了必要科目之外还可以学到更多的东西。可以发展更多实用技巧。另一方面，学生可以培养他们的兴趣，学习不同的东西。虽然因为教育注重分数导致开设特色课程有一定难度，但我相信总有一天将会开设更多的特色课程，因为教育改革呼吁人们关注学生的思维发展。

Dear Ling Feng,

I would like to thank you at the end of our middle school education. You

have been very kind and helpful since we knew each other.

You have given me so much help that I will never forget. Last term, I

caught a bad cold and had to stay at home for a week. When I was worrying about

the lessons, you came to my home after school and helped me with every subject.

With your help, I didnt fall behind others. Since then, we have become very

close friends. I think Ill try to help others just like you.

Thank you again. Even though we may go to different schools, Ill always

stay in touch with you. I wish you success for the future.

Yours,

Liu Yan

“保护环境，人人有责。”这是连幼儿园小朋友都耳熟能详的一句话。但是，人们却没有理解它的真正内涵，保护环境，是我们每个人都必须要做的，也是理所当然要做的，这并不是领导，扫地工人的事，这是我们全人类都要做的事。

因为现在的环境已经不容乐观，再这样下去，后果将不堪设想。就拿家乡的那条河来说吧，原本河边长满了绿草、花朵，河水也清澈见底，还能看见几只小鱼小蟹。小时候，我舅舅还带我来游过泳，但，现在呢?采砂机一来，河水就变得浑浊不清。原本长在河边的小草小花，一个个都垂着头，苦着脸，好像在说：“这可恶的采砂机，害得我们的生命之源——水都变得肮脏了，唉——”还有，农民们开辟的水沟里的水也不能用了，因为这混杂了泥沙的水显然不利于庄稼生长，这就苦了农民们，要把原来的水沟堵起来不说，还要从自己家里带水来，浇灌庄稼。你看，就因为采砂，弄得那么多人麻烦，虽然你们是赚钱来养活家人，但是你们为什么一定要把这么清澈的河水弄成这样?这到底该怪谁?

因为我知道现在大气污染大体是汽车尾气造成的，所以我专门调查了一下汽车，真是不查不知道，一查吓一跳!全世界目前竟然拥有11亿辆车!按照正常行驶来算，每辆汽车每天排出约24kg的废气，也就是说，全世界每天会排出264亿kg废气，等于2640万吨!你自己想想看，这是有多恐怖啊，一股废气扑面而来……恐怕不被吓死也要被熏死了吧。所以，大家要少开车，多骑车，绿色出行，才能使我们的环境更加美好!

塑料袋，是我们生活中很常见的物品，它轻巧，简洁，还方便，深受广大市民的喜爱，但是，在背负美誉的同时，它也有个不好听的外号，名叫：白色垃圾。没错，塑料袋虽然集众多优点于一身，但，它有个致命的缺点：会污染环境!丢一个塑料袋会污染0.6平方米的土地，按照平均每个人丢一个塑料袋计算，宁海每天就会有60万个废塑料袋，就算被扫掉一半，还是有18万平方米的土地被污染。请问，把自己称作宁海人的你，有没有干过这样对不起宁海的事?千万不要说没有，我们所有人都干过，我们现在所能做的，就是不要再扔塑料袋了，宁海的土地，没有多少啊!

“保护环境，人人有责。”我希望大家能真正做到这一点，不要理解错其中的含义，不要以为扔一个塑料袋没什么了不起，土地是大家的，不是你一个人的!不要再执迷不悟了!

Protect Environment

Today there is more and more pollution and the environment is becoming worse and worse. So we have to know how to protect the environment. Here are some ways.

First, we can stop driving our personal cars. We can go to school or work on foot or by bus. Not only can it protect environment, but also it is good for our health.

Second, we are not supposed to drop litter anywhere, we should put them into the trash bin. And it’s best to pick up the litter on the ground when we see them.

Third, we should save the paper, the water, the food and so on.

Fourth, we should protect the trees and we should plant more trees.

I think if everyone does something to protect the environment, our world will be much better.

[保护环境的英语作文4篇

地球，是人类的家园，也是万物共同生长的家园，她无私地为人类奉献着自己。绿色为地球家园提供清新的氧气，我喜欢绿色，喜欢那嫩绿无比的小草，喜欢那苍翠欲滴的大树。

这样想着，不知不觉中，我又幻想起数万年以前的地球来，那时，还是一片片原始森林，四周静悄悄的，大树随处可见，清香的空气，偶尔可以听见几声清脆的鸟叫。蔚蓝的天空，漂浮着几朵棉花似的云朵儿，展翅高飞的鸟儿在空中自由的翱翔。走入森林，还能闻到淡淡的花香味，不一会儿，到了一条小溪边，这条小溪很清，清的可以看见溪底的石头，用手捧起一手，一喝，嗯，甜甜的，我完全沉浸在这美丽的世界中，无法自拔……

直到“叭叭叭”的喇叭声传来，我急忙睁开眼睛回到现实，穿上外套，冲出了家门。街上的人们一个个带着雾霾口罩，天上灰色的一片，已经看不到天空。吸一口气，啊!进入鼻中的不是清美的空气，而是恶心的烟臭味。一路上，到处堆放着人们随手丢弃的垃圾，什么盒子呀，烟头呀，纸巾呀，虽然已经这样了，但人们还是在永无止境地扔垃圾。地球这个家园已经被人类毁灭得狼狈不堪，在这片土地上已经很难再找到一块干净整洁的土地了。

有这样一则新闻引起了我的注意：众所周知，黄河，是世世代代中华人民的“摇篮”。可是，据统计，黄河在2000年来竟决口1500多次，改道26次。到底为什会出现这种情况呢?说来有趣，黄河在前1000年至前10000年来，黄河的自然条件是黄土高原最好的，正因为如此，我们的祖先才选择在这里生存。但现在，黄河变得凶猛起来，成了中华人民的一个烦。近年来，黄河含沙量大幅度提高。至于为什么会出现这种情况，专家给出以下说法：随着人口增多，人们过度砍伐树木和过度放牧，导致黄河失去了天然的保护层，进入河中的沙石越来越多，最终黄河成为中国十大危险河流之一。

这些都说明保护环境极其重要!为了我们的子孙后代能更好的在地球上繁衍生息，让我们携起手来共同保护环境，共同保护我们的地球家园!从我做起!从今天做起!
