英语作文：人类活动破坏了环境20篇

我们的祖国虽然资源、物产比较丰富。可是，你知道吗?光光这些都还不够，更重要的是要注重环保!

Although our motherland is rich in resources, products. But, you know? Only these are not enough, it is more important to pay attention to environmental protection!

我觉得，政府应该多多提倡环保，多多参与环保工作，为环保做贡献，组织好环保是最关键的。你们说，是吗?

I think, the government should take to promote environmental protection, actively participate in the environmental protection work, make a contribution to protecting the environment, organization of environmental protection is the key. You say, yes?

首先，应该告诉市民，要关注每一件环保的事，积极做环保工作，不要随手扔垃圾、看到垃圾要及时捡起。其次，要把废旧电池该扔哪的问题解决好，应该把这件事给做得更完善：在一些地方分放一些回收废旧电池的筒，每天都有专门负责的人去取。这样一来，不管是住在偏远地区，还是住在热闹的地方，都可以很方便的把废旧电池处理了，再也不会发生人们不知道废旧电池怎么处理，就把废旧电池扔进垃圾箱里的事了。最后，政府应该增加一个环保工作者的职务，让更多的人投身于环保工作当中!

First of all, should tell the people, pay attention to every green thing, to do environmental protection work, do not readily throw garbage, garbage to pick up see. Secondly, to throw the waste batteries which to solve the problem, should put this thing to do better in some places put some recycling waste batteries, cylindrical, every day there are responsible for people to get. In this way, whether it is to live in the remote areas, or in the bustling place, can be very convenient to the handling of used batteries, and it wont happen again and people dont know how to deal with the waste batteries, waste batteries thrown in the garbage again. Finally, the government should increase a environmental protection worker job, let more people involved in environmental protection work!

为了环保，行动起来吧!

To be environmentally friendly, action!

Environmental protection, the subject, is a household name, everyone knows. But in real life, some people still dont too seriously, think small, in my opinion, environmental protection should start from the pretty little things. I have experienced such two things: one day, I go to the supermarket to buy things, quickly to the door of the supermarket, see several send out flyers, see to, see cars, but some people dont, casually throw on the ground, I used the paper in the trash. Saw the two men, the propaganda time with glue on the wall, from a distance, like pieces of "psoriasis" while they do not pay attention to, and I took out my skills "tearing work", ha ha, I get rid of a large "psoriasis" is. At another time, I play in the bottom of a floor, find the distance on the grass up whereas white smoke, a closer look, it turns out that there is a group of children in our class burning grass, grass black a large, I hurriedly stop as a big brother, and about the dangers of fire and the importance of environmental protection. They are ashamed, quickly the coming water from the nearby end extinguish fire, finished burning grass action.

We human beings are living on a planet, that is the earth. On earth, have for the oxygen we breathe, there are dense forests, vast grasslands, boundless sea, all kinds of animals, constitute the beauty of nature.

I think loudly called on the people: the earth belongs to our human, belongs to all of us, as long as with our hands, starts from me, starts from everyone, protect the environment, the love of the earths natural resources, make clear pond water still flowed in the home, flowers in full bloom the flowers still.

Human ah, should be time to wake up, open your eyes and look around us, this is our home, let us from now on, wash his with their own hands, with their own wisdom, with their own conscience, for our children and grandchildren keep a harmonious and beautiful homeland, let us make an efforts to us from generation to generation for survival!

环境保护，这个话题，可以说是家喻户晓，人人皆知。但在现实生活中，一些人还是不太重视，认为微不足道，在我看来，环保要从件件小事做起。我就经历过这样两件小事：有一天，我去超市买东西，快到超市门口时，看见有几个散发宣传单的，见人就给，见车就放，可是有些人却不要，随手就扔地上，我过去将纸扔进垃圾箱里。又看见两个人用胶水将宣传单贴在墙上，远远望去，活像一块块“牛皮癣”趁他们不注意，我又拿出我的绝活“撕纸功”，哈哈，“牛皮癣”被我除掉了一大片。还有一次，我在楼底玩，发现远处草地上冒出了缕缕白烟，走近一看，原来，是我们班一群小孩在那里点火烧草，草黑了一大片，我以大哥哥的身份连忙制止，并讲了火灾的危险性和环保的重要性。他们羞愧难当，赶忙从附近端来水把火熄灭，结束了烧草行动。

我们人类都生活在一个星球上，那就是地球。地球上，有供我们呼吸的氧气，还有茂密的森林、辽阔的草原、无边无际的海洋、各种各样的动物，构成了美丽的大自然。

我想大声呼吁人们：地球属于我们人类，属于我们大家，只要用我们的双手，从我做起，从人人做起，保护环境，爱护地球上的自然资源，让清澈的塘水依旧流淌在家乡，让花儿依旧那样鲜花盛开。

人类啊，是应该觉醒的时候了，睁开眼，看看我们的周围，这是我们的家园啊，让我们从此金盆洗手，用自己的双手，用自己的智慧，用自己的良心，为我们的子子孙孙留下一个和谐、美丽的家园吧，让我们为我们世世代代的绵延生存做出一份努力吧!

There is a little girl named lili, she is very lovely, very beautiful!

Today is Arbor Day, lili came to a sunny and beautiful place. She took the bucket and the spade, and first planted the tree in a green meadow, then watered it, and then pulled the weeds. After the tree was planted, lili came to pull weeds and water every morning. Some days later, lily came to the pleasant place. She saw that the saplings had grown up. The birds are singing happily, the butterflies are dancing in the trees, the flowers and grass nod happily. The little bird made the tree home, and the birds and the butterflies were all around lili.

Lili is so happy!

Last weekend, my family and I went to a beautiful xixi wetland.

Although there is beautiful scenery let us ecstasy, but we also saw a shocking scene.

That day, I took familys hand off the small wave rolled ship. I carefully step, on the wave rolled the ship, and also rickety at the beginning, but after sit tight, boat slowly calm down, rocking boat rowing OARS, calm water suddenly rolled up ripples. But the ship opened to open water, water quality is very bad, I saw the water no longer sparkling, but cloudy oil floating on the surface, packing box and plastic and other trash littering, originally clear water becomes cloudy. So muddy water at this moment, I think that must be a box of oil flow into the water, so will only be so dirty!

On the way back, I said to himself: "if everyone care for the environment, protecting the rivers, that every environment clean and beautiful, every river bottom!"

Lets do it together five water to rule the propagandist and executor, let us take good care of the environment, protect our home together.

上个周末，我和我的家人一同前往美丽的西溪湿地游玩。

虽然那里的优美风景让我们入迷，但是我们也看到了令人震惊的一幕。

那天，我拉着家人的手走了那小巧的摇撸船。我小心翼翼地迈出一步，踏上了摇撸船，一开始还摇摇晃晃的，但坐稳后，船便慢慢地平静下来，摇船者划着桨，平静的水面顿时卷起波纹。可是船一开到开阔的水面，水质则非常糟糕，只见水面不再波光粼粼，而是浑浊的油污漂浮在水面，包装盒和塑料袋等其他垃圾随地可见，原本清澈的水变得浑浊不堪。这时的我想，水这么浑，一定是包装盒的油污流进了水中，所以才会这么脏吧!

在回去的路上，我自言自语地说：“如果所有人都爱护环境，保护河流，那每一处环境都会干净、美丽，每一条河流都会清澈见底!"

让我们一起做五水共治的宣传者和执行者，让我们一起爱护环境，共同守护我们的家园。

Depending on personal experience, personality type and emotional concern, we find that some people hold the idea of living in the country, while others prefer living in the city. In my opinion, I prefer the city life, though it has advantages and disadvantages.

First of all, city life is very colorful. City is the center of the surrounding area. So, it is also the most booming place having the best things. There are many great things and wonderful activities in the city, while there isn’t in the country. For example, there are KFC, wonderful shopping mall, delicious food from various places, dancing club, different kinds of activities and so on. We can also learn the culture from all the countries. Despite city life is so wonderful, it still has many disadvantages. Nowadays, with the improvement of people’s living standard, people have more cars and more people come to city, and then the city becomes more and more crowd. As a result, traffic jam emerges, which makes great inconvenience for people to go out. What’s worse, the air pollution becomes serious day by day, which is bad for people’s health.

To sum up, every coin has two sides. Living in the city also has good side and bad aspect. Whether like living in city or not depends on individual thinking. As myself, I like living in city though I know the disadvantage of living in city.

Educational activities教育活动

近日，你班在“知荣明耻” “八荣八耻大家谈”教育活动中，召开了一次关于学生荣辱观的主题班会。存在的问题1．不尊敬老师、家长等。2．学习散漫、考试作弊等。3．乱扔垃圾、污损环境等等。

Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful. （最近我们班开了个班会讨论什么是光荣和耻辱。）It is really a pity to see all this in our school.（很遗憾在学校看到这些现象）Some students don’t respect their teachers or parents. （不尊敬老是和父母）Some don’t take their studies seriously and cheat in exams. （作业不认真，考试作弊）Some throw wastes everywhere and pollute the environment . （到处乱扔垃圾污染环境。）It is honorable to obey the law and rules , care much about our class and study hard.（关心班级、努力学习、遵纪守法是光荣）It is shameful to break school rules, to be selfish or to make little effort to achieve success.（违反学校纪律、自私 骄傲是可耻的）We should respect others and think more of them than of ourselves.（我们应该尊敬别人经常关心别人）We should work hard and make much more progress to repay the society.（我们应该努力学习取得更大进步从而回报社会。）We should try our best to keep the environment clean。（我们应该想方设法保持干净的环境。）

Harmony with the environment is that we live in on Earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on Earth, the animals. Plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. Therefore, the environment must be linked with social ethics, character education and practice acts as an important element of it. Everyone must fulfil its responsibilities and obligations to protect the environment.

人与环境是和谐相处的，我们生存在地球上，人是自然之子，而不能仅把人看作自然的征服者，大家都知道，人类只有一个地球，地球上的山山水水、动物。植物是人类的细胞，如果我们把它损坏了，破坏了大自然的组织，等 于消灭人类。因此，环境要与社会公德联系起来，与实践行为作为人格教育的一项重要内容来抓。每个人都要履行保护环境的责任和义务。

Dear John,

Im glad to hear from you. Now let me tell you something about our city. Nantong is trying to set up a national civilized city. We middle school students are also doing some things for it. We are all polite to our teachers. (In class, we listen careful to them./When we meet them, we always say hello to them./…)We also respect the old. For example, we help them cross the streets.

We are always ready to help each other.(When one has difficulty with his studies, others will help him at once./...)We often show our love to those in trouble. Last month, the students of my class donated money to the earthquake-hit areas.

Besides, we plant trees to protect the environment and make our city more beautiful.

Nantong is my hometown. I will do my best to turn Nantong into a civilized city.

Zhang Tong

In the last several decades, our earth has been extremely polluted, such as air pollution, water pollution, noise pollution and so on. In recent years, the extreme weather becomes more and more frequent. Winter gets colder and summer becomes hotter and it rains more frequently. All of these warn us that protecting the environment is a serious and emergent event. As our general people, we should build proper lifestyle. We should pay attention to water and light saving. When we go out, we should firstly choose the public transportation. The most important is that we must realize that we can do a lot of things to protect our environment. Its our duty to make our home better. Let’s change from ourselves.

In modern society, we tend to become more and more aware of our living environment or physical environment, because we are not clean as before. So many people now choose their house as to its environment but not its location and expenses to afford it. As we all know, the environment pollution is more and more serious during these years, what we could do is to make great efforts in protecting environment gradually. As to government pollution, as to common people. We also try to protect it and make it remain clean. Although we have managed to protect the environment to a certain extent. It is still a very long way to go.

Protect our enviorment The earth is our home,we must take care of it.We shoule make a less pollution as we know everybody in north America makes 1000 kilograms of the garbage everyday. Most of it is packaging Most of garbage turns into soil but not to plastic,plastic keeps for many years it will pollute our environment so we shouldn’t waste thing we should make some things for recycling .

在现代社会中,我们往往更加了解我们的居住环境还是自然环境因为我们不干净如故.现在这么多人选择它作为自己的房子,而不是它的位置和环境费用负担.众所周知,环境污染日趋严重,这些年来,我们可以做的是努力保护环境,逐步实现.至于政府的污染,为百姓.我们也设法保护它,使之保持清洁.虽然我们已能在一定程度上保护环境.它还有很长一段路要走.

保护我们的环境 地球是我们的家园,我们必须照顾好它我们应该使减少污染,如我们所知大家在北美的垃圾进行1000公斤。大多数都是包装大部分垃圾变成土而不是塑料制品,塑料保持多年来它会污染我们的环境,所以我们不应该浪费我们应当做些事情回收利用。

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

As a college student,I can be responsible to say that all my classmates dream about getting a satisfying job,and devote themselves to this career in an perfect environment.Certainly I am not an exception too,though nowadays there is a growing employment pressure . For many students, a satisfying work environment may be the aim of four-year college life,I also hope I can work in a colorful and competitive climate in the future .At first,I can get a handsome salary so that I live a comfortable life .Although salary is not the main factor , most of people they cannot neglect salary,because job with low salary cannot hold water for the young men . Whats more, I can learn more working experience and get a wide view to increase my knowledge，because I think there is no limit to knowledge and if one person wants to take a great progress in his career learning is the only way .In finally ,I hope I can meet a competitive opponent.There was a saying by Charles darwin:” It is not the strongest of the species that survive,but the one most responsive to change”.So I think competition is conducive to progress. There is no doubt that everybody want to get a perfect job,but employment pressure has been a problem that we cannot overlook.So we have to spare no effects to improve ourselves ,I believe that we can get a satisfying job as long as we constantly strive to study.

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

This August I went to a two-week long English camp which was held by English Beacon in Yantai city Shandong Province. There were over a hundred middle school students from all over the country and thirty experts in English teaching participating in this exciting camp.

While we were there it was required that we speak only English to our teachers and with each other.

We also visited many places of interest. Learning English was exciting and the teachers were very friendly and helpful. This camp was a real life-changing experience that I will never forget.

My favorite extracurricular activity is to pick up white trash. This is not, the new year, and the school has three days off. Im finally looking forward to my favorite activity again.

This time, I gather white trash with my mom and dad. At the bus station, we saw our "enemies" in rows and lines, as if they were going to attack us at once. I and my father, mother rushed to catch and hook, the result "enemy" did not catch, and the three of our hooks hook together! At this time, I realized that I would not be in a hurry.  So, I said to my mother and Dad, "come on, lets come to the two sides, so that we can wipe them out all the time..." I went back to my own post with my father and mother to discuss the plan.

This time, theres a good show. Only to see, with a large paper shell, she fan the sky and fly many "enemy" fans to the sky. I suddenly lifted up the hook, to our "enemies" a catch, suddenly caught two or three, I jumped up, and immediately sent them to my father to take the old rice bag, in this way, even continued, back again and again, finally put all the "enemy" caught, the "enemy" sold thirty or forty yuan!

I like this activity. But I hope that the next time I can pick up the "enemy" less and less, let us the sky more blue, let our air fresher!

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.

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.
