我们应该怎样保护环境英语作文初中(通用20篇)

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。

As the drawing presents, there is a man walking across the street

absorbedly focusing on his cell phone without noticing the surroundings. This

sort of phenomenon is not uncommon and rare in some metropolis, especially among

the youngsters.

What the picture illustrates is the prevailing situation that has long

existed in todays China. That is the mobile phone obsession. With the advent of

information age, people are becoming

increasingly fascinated on the electronic products, especially the cell

phones. Not surprisingly, you could easily notice that most of us are obsessed

in sending messages, playing online games with their mobile phones. It cannot be

denied that this phenomenon may negatively impact the relationship among people,

and therefore they will become estranged and isolated.

Personally, in view of the overuse of mobile phones, I hold that we

individuals should raise the necessary awareness that good relationships are

reinforced by sincere and face-to-face communication.

【猜题理由】随着经济的高速发展，社会自然环境遭受严重污染。环保意识的培养和环保工作的开展成为国人，乃至世人共同关注的热点和焦点。对环保问题而言，"只要人人献出一点爱，世界将变成美好人间 !"此话题为学生熟知，与高中生的生活实际贴近，而且具有一定的开放性，使得每个学生都能够有话可说，符合新课标理念下的命题方向。

【构思点拨】首先简要介绍环保问题之重要，号召同学们行动起来，共同参与环保活动;其次就环保发出倡议，并征召志愿者。这样既把考生限定在一定范围之内，又给予了考生相当的发挥的自由，有助于考生的作文脱颖而出。

Here is a great one not to be missed by any enthusiastic youth; Right next Saturday, our university is to run a publicity campaign to advocate environmental protection across the city. The University Students Union will be in charge of recruitment of volunteers. Lets join our hands and take action immediately.

Mobile phones are useful and popular. But they are also bad for us

students. On the one hand, some of us like playing the games, they will forget

the time to rest. If they dont get enough rest, they will feel sleepy in class.

And even they are having a class, they always think about the games. They are

not good for our study. On the other hand, there are a lot of students who like

reading e-books on a mobile phone. Its good to read. But reading on a mobile

phone for a long time is not good for our eyes.

st 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.

Computer is a very useful machine. Some of them are big, but some of them

are very small .Many people like playing computer. Computer has many functions,

so that people can do a lot of things by computer, like watching movies,

listening to the music or playing games. It can make our lives very colorful and

convenient. Various people can make good use of computer. Children can use

computer to learn and play games. Parents can use computers to work. I think

computer is a kind of wonderful and interesting machine, so I like computer very

much.

天空的幸福，是它穿着一身的蓝阳光的幸福，是它拥有如水晶般耀眼的光彩大地的幸福是它孕育出多彩的生命而我的幸福，是有一个能使我健康成长的乐园——地球。

蓝蓝的天上白云飘，白云下面马儿跑这首六七十年代的歌曲唱出了当时人们对环境的热爱与赞许。然而我们现在感受到的是：蓝蓝的天，蓝蓝的梦，蓝蓝的云，蓝蓝的美。可是我们却怎么找也找不到那样的环境，头顶上总是被那乌蒙蒙的天包所围着，城市中高耸入云的烟囱林立，滚滚浓烟如同黑龙腾空，随后又变成尘埃散落下来，钻进我们的鼻腔里，损伤我们的心肺。汽车穿梭在宽阔的马路上，释放出来的尾气使洁白的道路又添上了一到抹不去的疤痕，还把我们熏得直咳嗽。这样的环境，对我们意味着什么？意味着不知不觉的伤害着我们的身体。

还有，以前那汹涌澎湃的黄河，那中华民族的母亲河，可如今，长年泥土沉积，河床提升，洪灾频繁。以前那奔腾不息的长江，那中国人民的摇篮，可现在，已不在是清澈明亮的了，许多工厂排出废水、废渣，使这条玉带逐渐失去它的光彩。这样的环境，对人类意味着什么？意味着人们喝到的最后一滴水，将是自己的眼泪。

还有，在鸟语花香的大森林里，早已不再有以往的快欢。随着工业革命的启动，动物的家园糟到了破坏，人们来到森林，随心所欲地砍伐着树木，做成舒适的家具，拿来贩卖。正在这个时候，你们有没有听见，树木发生出了惨叫，一声比一声高，一声比一声强烈。它们惊恐地睁大眼睛，眼睁睁地看着自己的家园被人类毁灭，逃的逃，奔的奔。砰——一声声枪响，一只只动物挣扎着躺在了血泊中，那一张张冷酷的脸，映在动物们绝望的眼中。还我们的家园！鸟儿在呼唤。还我们的快乐！树木在呐喊。这样的环境，对我们又意味着什么？意味着人们能不能呼吸到最清新的空气。

你们知道吗？现在中国的沙漠和戈壁滩总面积达150多万平方公里，占全国版图的15%，这个严峻的数字太可怕了。世界上森林的平均覆盖率是22%，而中国——这个拥有着13亿人口，960万平方公里土地的泱泱大国，森林覆盖率却只有12.7%，与其它国家相比，相差甚远。

多么骇人的数字！

多么鲜明的对比！

多么严峻的挑战！

我，作为一个炎黄子民，怎么能不感到心酸呢？我时常想：如果人类变了，那我们的世界将会是一个充满爱与鲜花的人间仙境。

环境，对我们意到底味着什么？答案我们都知道，它意味着人类生命的起点和终点。环境，总是在你我践踏着它，忘了珍惜它的时候，最美好的悄然逝去。如果，有一天时间能倒转，我将倡议所有的人们一起将我们索取的完全的还给大自然，我敢断言，那时，人类也就找回了曾经安身立命的家。

Environment, is the source of our lives; In this environment, is the human survival; Environment is the human the beacon; If we dont take care of it, it will lead to the death of human society.

In the long river of human history development, there are many celebrities attaches great importance to the environment. British poet byron once said: "I love not man the less, but more love the nature." French monte nie also said: "we have receded from the nature, she was so accurately the way for us, and we want to use her to teach to teach her." What these celebrities said let us understand how important it is to protect our environment.

I cant help but think of the lawn culture in the United States. The lawn for americans create a better living environment, also has brought immeasurable benefit. People can fully share the gift of nature, not only the air is fresh, but also to adjust the temperature, give people the feeling of the quiet and serene. Americans pay attention to the lawn has become a tradition, and even has become a cultural phenomenon. And the lawn culture coexist is American good social morality consciousness. Especially holiday people walking on the lawn, play ball, dinner and all kinds of recreational activities, and in the atmosphere of comfortable, quiet and tastefully laid out and is inaccessible by the indoor activities. We should also like americans, take good care of the lawn, attaches great importance to the environment.

On the other hand, the earth gives all people is the essence of the matter, but in the end, it returns from people is a waste material. In 1991, a team met with snow when climbing mount Everest. To their surprise, the sky floating black and made the earth and the sky shrouded in the haze. Cause of the black snow is the outbreak of the gulf war in 1990, has brought severe disasters to the environment, due to the loss caused by environmental pollution is far more than the direct economic losses of war. From this story, we deeply understand the disaster caused a great loss, we want to make the world become beautiful, must take good care of the environment, cant be destroyed.

"To protect the environment, everyone duty." Lets pull up hand and create a harmonious society; Lets pull up hand, create beautiful homes. Lets pull up hand and create a better tomorrow.

环境，是我们的生命之源;环境，是人类聚集生存之本;环境，是人类指路明灯;我们如果不爱护它，它就会导致人类社会的死亡。

在人类历史发展的长河中，有许多名人很重视环境。英国的诗人拜伦曾说过 ：“我不是不爱人类，而是更爱大自然。”法国蒙台涅也说：“我们已经背弃了大自然，她曾那样准确地为我们指路，而我们却想用她的教导来教训她。”这些名人所说的话让我们明白保护环境是多么重要。

我不禁想起了美国的草坪文化。草坪给美国人创造了美好的生活环境，亦带来了难以估量的好处。人们可以充分分享大自然的恩赐，不仅空气清新，而且也调节了气温，给人们恬静、安详的感受。美国人重视草坪已成为传统，甚至已发展成为一种文化现象。与草坪文化共存的是美国人良好的社会公德意识。特别是假日人们多在草坪上散步、玩球中、聚餐和进行各种娱乐活动，其舒适、幽雅之氛是室内活动所无法企及的。我们也应像美国人一样，爱护草坪，重视环境。

反之，大地给予所有人的是物质的精华，而最后，它从人们那里得到的回报是物质性的垃圾。1991年，一支登山队在攀登珠穆朗玛峰时遇到了大雪。令他们惊奇的是，天上飘下的黑色雪花纷纷扬扬，使大地和天空笼罩在阴霾中。引起这场黑雪的原因是1990年爆发的海湾战争，给环境带来了深重的灾难，由于环境污染造成的损失远远超过战争的直接经济损失。从这件故事中，我们深深地了解这场灾难造成了很大损失，我们要让世界变得美丽，一定要爱护环境，不能再破坏了。

“保护环境，人人有责。”让我们拉起手，创造一个和谐的社会;让我们拉起手，创造美丽的家园;让我们拉起手，创造一个美好的明天。

Recently, the problem of environmental pollution is getting more and more

serious. The air pollution, noise pollution and water pollution are found on the

newspaper everywhere. It is obvious that we should do something to protect our

earth. Because we have only one home. We should try our best not to pollute the

environment and appeal the people around us make their effort to protect our

unique home.

Nowadays mobile phones are becoming more and more popular among the middle

school students. Some students think that it is easy to use them to keep in

touch with parents and classmates.Also，they can be used to listen to music or

take photos. But others think that we dont need to talk with parents and

classmates with mobile phones，because we meet them every day. And mobile phones

may influence our study。

In my opinion，its not wrong to follow the fashion，but the most important

thing is how to use the mobile phone in a right way。

We should all know that everybody is responsible for protecting the environment!

We live the earth is very fragile, the earths natural resources is limited, if we protect the environment and the earth from now on, we live the earth will become more beautiful!

Protecting environment starts from me from the us side of small start!

To protect the environment is to protect the earth or indirectly protect us humans, if the environment is destroyed, then to the survival of our homes is likely to be swallowed up by the desert!

I am here is appealing to people around the world to protect the environment is everyone duty! If we are in such environment, our home is about to be collapsed. Then we will have no place, everybody is responsible for protecting the environment, start small make up,

If we do not litter, spit, etc.

Everybody is responsible for protecting the environment!

我们大家应该都知道保护环境人人有责!

我们生活的地球是很脆弱的，地球上的自然资源也是有限的，如果我们从现在开始保护环境和地球的话，我们生活的地球一定会变的更美好!

保护环境从我做起从我们大家身边的小事做起吧!

保护环境就是保护地球还是间接的保护我们人类自己，如果环境被破坏的话，那么我们赖以生存的家园就很有可能被沙漠吞噬 !

我在这里向全世界的人们呼吁 保护环境人人有责 ! 如果我们还在这样的破坏环境的话，我们的家园即将遭到崩溃 。 那时我们便没有去处了， 保护环境人人有责 ， 从小事开始作起吧，

如我们不乱扔垃圾， 随地吐痰等。

保护环境人人有责!

我是外国语学校的一名小学生。

我看见许多河水都被污染了，从而导致人们经过此处时都捂着鼻子绕道而行。

有一天，我和妈妈到九峰公园玩，我看到有的人为了图方便，将手中的垃圾随手扔入河中。加上附近的厂家都大量排放废水、污水，这些水流入河水中，使小鱼无法正常生长。进入九峰公园，可见一堆堆垃圾没有了家，一个个静静地躺在那儿，散发出臭气。

我还发现：有些叔叔阿姨在吃饭时，都在使用一次性木筷;有些人的家里还在使用珍贵木材用品;有些人的家里还没有使用节水型用具......

因此，我向厂家、居民提出以下建议：

第一：将保护河水的牌子立在河旁。

第二：在河边围上栏杆。

第三：制作“爱护河水”的宣传板报，周日去宣传。

第四：住在河边的同学首先做到不扔垃圾到河水中，并劝阻家人别这样做。

第五：派人监督，发现屡次犯规者进行严重处分。

第六：不用一次性筷子。

第七：不是用珍贵木材用品。

第八：使用节水型用具。

我们要从小事做起，从自己做起，人人争当“爱水、护水”的小卫士。

The ends of the earth, the world is so vast, two people who were originally

unknown, but because of big or small events and meet, may also experience a

large list of twists and turns, finally become the friends to know each other.

The probability is too little, so every one of my friends are special, and every

friend is precious. This friendship if lost, will be unusually hard to find. So,

friendship, isnt it a kind of predestination?

Friendship is not only a kind of fate, but also a warm.

I am a girl of ten, and I live in a small mountain village far from

Taiyuan. The only person that lives with me is my mother, because my father is

away for eight years, working in a city.

During the Spring Festival, my father came back home. He looked thin and

tired. He gave my mother two thousand yuan, and told her that he would work even

harder, earn more money, and then he could take us to the city He stayed at home

for only ten days.We are living a poor life now. But what I want most is not

money, but my father. I miss him very much!

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。为了保护它们，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，我们这样做是非常重要的。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一样，纸，瓶，等。我们以这种方式可以节省资源。

我是只可爱又善良的啄木鸟，大树爷爷给我一个很轻松的任务，他说“小叽喳，从今后你的任务就是捉树虫，加油干！”我激动的点点头。

带着这个光荣而艰巨的使命，我飞遍整个森林，虫子见了我都躲，我简直是“打遍天下无敌手”。

有一天早晨，当我还在睡梦世界遨游时，一声巨响好似一只巨大的手把我从睡梦中拉醒，揉着睡眼朦胧的眼睛一看，睡意全无：我居住的大树旁，一棵树倒在地上，怎么回事，我发起呆来，“嘭嘭嘭……。”我居住的这颗大树忽然颤抖起来。我连忙飞下树，看到一个手持斧子，长着一段木头似的人在砍树。心想“讨厌的家伙，看我怎么收拾你！”我立刻飞到他头上，大喊“这段木头中一定有一条有肥又大的坏虫，或许还不止一条，待我把它捉拿归案。”说完，我使出平生的力气，把他的脑袋啄得“咚咚”响，啄到第十五下时，他的后脑勺被我啄了许多大大小小的疱。只见他速度越来越慢，越来越力不从心了，最终扔下手中的斧子，抱着头大叫着逃走了。第二天，《森林日报》上刊登出：森林小英雄小叽喳，勇敢的战胜了愚蠢的人类！从此以后，每天我都会在森林中巡逻，再也没有一个人类敢来到这儿砍树了。

有一句名言说得好：“保护环境，拯救世界，就是拯救自己”，人类，你愚蠢、你可怜，你以为砍了树，盖了好房子，做了新家具，就能过上好日子吗？你有没有想过，不爱护地球、不保护环境，沙尘暴终究会来纠缠你，世界将会变成一片沙漠。人类，醒悟吧！

Everybody has someone in his heart that he admires very much， who may be a scientist， a writer or a musical or a movie super star。 As for the one I admire the most is my dear mother。

My mother is an honorable policewoman。 She is very busy with her job all the time。 As mom often needs to work over-time， she goes to work very early in the morning， and doesn’t come home till late at night。 Mother deeply loves her work; she treats it gingerly and conscientiously， and she is full of respected at work by her colleagues and leadership。 For always being a responsible person for the work， my mother also therefore merited many awards。

In my memory， from my childhood， my mom rarely took days off， not even for the public holidays。 When my friends went out to play with her parents on weekends， I spent my time in mom’s office。 Whenever mom had a day-off， she would be busy with preparing a delicious meal for my dad and me。 There was one time， when we were just about to start our lunch， an emergency telephone call rang up， mom hang up the call， got dressed to get ready to go out， she was even too busy to think of the meal， then rushed to her work。 Till my bedtime on that night， mom was still not home yet。 My mother works extra almost everyday， she never seems to know when she should stop it。

I admire my mom’s work spirit! I love my dearest mother!

Sea pollution is becoming an increasing problem for our planet and we have

a responsibility to reduce sea pollution.

I need to describe the problem. Our ship currently dumps all its rubbish

into the sea.Its easy to result in huge endanger. First of all, Non-organic

substances such as plastic bags kill fish and whales. Because fish get trapped

and whales cannot digest them. Secondly some rubbish is inherently toxic.

I can suggest some solutions. First and foremost we can create a better

system of disposing of rubbish for instance. We ought to store rubbish. Next, we

are supposed to make ships environmentally and friendly. A case in point is that

we should stop providing plastic bags.

We must act now before it is too late!

When we were children, we often say that I want to grow up, or I want to be

an adult. As children, we cannot do many things, while after we grow up, we can.

However, we often complain that I don’t want to grow up when we become adults

actually.

Firstly, growing up means more responsibilities. We should make a living by

ourselves or we should support our parents when they can’t earn enough money to

make a living.

Econdly, after graduation, we need to work instead of accomplishing

nothing. We should have a target and work for it, so we have pressure on

jobs.

Every coin has two sides. Grow up can also broaden our horizon, offer us an

opportunity to know more about our world, love and protect the important person

in our life. Don’t be afraid of growing up, just be a better person and enjoy

our life.

今天，我们在课里，上了自己一个具有特殊的讨论课——我为环保做贡献。大家开心得一蹦三尺高！

热烈的讨论比赛开始了，陶盛林争先恐后地回答，老师不知所措，但陶盛林回答得很好：“我们可以把油变成电，可以吗？”正在猛烈回覆的陶盛林被想象力厚实的赵佳乐打断了：“哼！还不如太阳能发电啊！再说了电也是中国煤炭以及烧成的。”他的声音一落，教室里就想起了沸腾的掌声和坚定的赞许。

从这个讨论中，我终于明白了，人也少开一天车，多种树，但树会产生二氧化碳的量小，但树木会吸收二氧化碳，氧气的排放。虽然保护环境，但人在家的时候最外面，所以必须保持一些鲜花在房间里，有助于我们的身体。袋说起，大家一定不陌生吧？但是，我们知道塑料袋对我们的身体造成损害，还会破坏大气，而且还坚持使用塑料袋吗？即使不使用塑料袋，还有大酒店啊，是啊……酒店用同样的危险和塑料一次性用品。所以，我要你用更少的一次性用品。

这次我们讨论我知道了，只要爱护生态环境，哪里都是一个美丽的。

The sun summoned the planet in the solar system to open an emergency meeting, the theme is to save the planet. The sun to see everyone to the Qi, and clear the clear voice, said: "The stars, our good sister earth has been at stake, the doctor said that her blood is toxins, the body of nutrients is also depleted, in this way "The moon says," In recent years, mankind has mined a lot of oil, minerals, wood and other materials, without protecting the environment, and the earths sister is not sick.

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.
