环境和人类英文作文精选两篇 作文带翻译【汇总20篇】

人类的生存空间日益侵占自然界的领地,例如毁林造田,填海造田等等,造成植物和动物的生存空间日益缩小,很多动植物濒临灭绝.并且造成大量水土流失.

人类的生活和生产垃圾日益污染大自然的环境,例如建筑垃圾,生活垃圾到处随意堆放,温室气体过度排放,造成全球气候变暖,海平面日益升高.生活污水污染水源,使水生动植物的生存收到威胁.

人类对自然资源的过度掠夺和开发,对种植物过度索取.例如捕杀野生动物,致使珍惜物种灭绝.

人类对自然的掠夺必然遭到自然界的惩罚.自然界对人类的惩罚让人类刻骨铭心的记忆,曾经让人类失去多少无辜生命的非典,之后出现的禽流感.还有大气污染同时也造成人类生存环境的破坏,导致疾病发病率的高升.沙尘暴肆虐,酸雨都是自然界对人类的惩罚.

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 bees 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?

与我们的生活水平的提高，越来越多的人都买得起汽车的。因此，道路往往没有堆满了汽车。然而，随着越来越多的废气排放是汽车、空气污染问题变得更加严重。所以此刻我们提倡过低碳的生活。

我的推荐是我们就应更经常骑自行车而不是开车骑一辆自行车，我们不仅仅能锻炼身体，也能保护我们的环境。为什么不试试，我亲爱的朋友?

Dear Miss Brown,

I am writing to express my sincere thanks to you for caring me in the last

two years. During the days of being your student, I learn a lot. Firstly, your

serious attitude towards teaching and our students moves me too much. You

inspire and push me to work harder and harder. Secondly, I fall in love with

English under the influence of you. As a student of science and engineering,

I’ve been thinking that English does no good to me, but you help me to find the

fabulous glamour of English that leads me to know a totally different world and

develop a different way of thinking. Finally, your continuous encouragement

supports me a lot when I meet challenges or difficulties. You said that

everything to the last will certainly become a good thing, if it is not, not yet

to the last. Every time, remembering your words, I am so inspired to keep

going.

Above all, I want to say thank you again and please accept my sincere

appreciation. Best wishes for you.

敬爱的布朗老师：

我谨以此向您表达我最真诚的谢意，感谢您在过去两年里对我的帮助。在过去的两年里，成为您的学生，我学到了许多。首先，您对教学和学生的认真态度使我深受感动。您鼓舞着我不断地努力学习。其次，在您的影响下，我深深地喜欢上了英语。作为一名理工科学生，我以前一直认为英语对我毫无用处，但您使我认识到了英语的魅力所在，带我走进了一个全新的世界，培养了不同的思维方式。最后，您的鼓励总在我遭遇困难或挑战是鼓励着我。您曾经说过：“每一件事情到了最后都会变成好事，如果不是，那说明还没有到最后。”每当想起您说过的话，我就有了坚持下去的动力。

最后，请允许我再次向您表达我的感谢，接受我真诚的谢意。献上最美好的祝福。

Environmental Pollution

Write a passage with the words and phrases given:

the problem of pollution, cause, artificial substances, release, waste products, industrial production, consumption of goods, bring it under control, agriculture, chemical substancea.

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，Environmental Pollution-环境污染，四六级写作《Environmental Pollution-环境污染》。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。

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。

自然环境是人类生存、繁衍的物质基础；保护和改善自然环境,是人类维护自身生存和发展的前提.这是人类与自然环境关系的两个方面,缺少一个就会给人类带来灾难.

我们生活的自然环境,是地球的表层,由空气、水和岩石(包括土壤)构成大气圈、水圈、岩石圈,在这三个圈的交汇处是生物生存的生物圈.这四个圈在太阳能的作用下,进行着物质循环和能量流动,使人类(生物)得以生存和发展.

据科学测定,人体血液中的60多种化学元素的含量比例,同地壳各种化学元素的含量比例十分相似.这表明人是环境的产物.人类与环境的关系,还表现在人体的物质和环境中的物质进行着交换的关系.比如,人体通过新陈代谢,吸入氧气,呼出二氧化碳；喝清洁的水,吃丰富的食物,来维持人体的发育、生长和遗传,这就使人体的物质和环境中的物质进行着交换.如果这种平衡关系破坏了,将会危害人体健康.

人类为了生存、发展,要向环境索取资源.早期,由于人口稀少,人类对环境没有什么明显影响和损害.在相当长的一段时间里,自然条件主宰着人类的命运.到了"刀耕火种"时代,人类为了养活自己并生存、发展下去,开始毁林开荒,这就在一定程度上破坏了环境.于是,出现了人为因素造成的环境问题.但因当时生产力水平低,对环境的影响还不大.

到了产业革命时期,人类学会使用机器以后,生产力大大提高,对环境的影响也就增大了.到本世纪,人类利用、改造环境的能力空前提高,规模逐渐扩大,创造了巨大的物质财富.据估算,现代农业获得的农产品可供养五十亿人口,而原始土地上光合作用产生的绿色植物及其供养的动物,只能供给一千万人的食物.由此可见,人类已在环境中逐渐处于主导地位.

但是,严重的环境污染和生态破坏也随着出现在人类面前.大气严重污染,水的资源空前短缺,森林惨遭毁灭,可耕地不断减少,大批物种濒临灭绝,人类赖以生存的自然环境正处在危机之中.日益恶化的环境向人类提出：保护大自然,维持生态平衡是当今最紧迫的问题.

how to save environment? i think we should do the followings: first, it’s best to ride a bike to school, don’t take a bus or a taxi. second, i will remember to turn off the lights when i leave the classroom. third, in my free time, i will collect the empty bottles and waste paper for recycling. the fourth idea is turning off the shower when i ‘m not using it. fifth, it is imporment to save water and money. also, i won’t spend too much money on expensive things. last, we had better not cut down the trees, we have to take care of the trees . i’ll try my best to save the energy, i hope i can do something for our country.

Dear Miss Jiang,

I am writing to share my ideas about our English class. Now, our main

material in the class is the textbook, which is reasonable. But I think we can

get some other resources, such as English magazines, songs, movies and so on. We

can learn the basic knowledge from out textbook, and get some more from other

materials. In addition, those materials are more authentic and practical, which

will be useful to our learning. Besides, by doing so, we can get more fun from

learning and develop our interest to English. Please take good consideration of

my advice. Thank you!

尊敬的蒋老师：

您好!我写信是想和你谈谈我对英语课的想法。现在我们上课用的主要材料是课本，这是合理的。但是我认为我们可以获取一些其他资源，比如英语杂志，歌曲，电影等等。我们可以从课本上学到基本的知识，同时从其他材料获取更多知识。另外，那些材料更真实和实用，这对于我们的学习会有好处的。此外，通过这样做我们可以从学习中获得更多乐趣从而培养我们对英语的兴趣。请您认真考虑我的建议，谢谢!

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.

2.We can’t live without water, but now the water was polluted. It is the biggest problem. It influences our daily life. So we should find a way to solve this problem. Water is important resources. In our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Let’s try to form a good habit and save things around us. Let’s do it from now on!

Fish can’t live without water. Plants can’t live without water. People can’t live without water, either. As you can see, the water is very important to us. But now drinking water is leand less. The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do nowI think we can plant trees, clean the banks of the river, water the plants by using used water. Turn off the shower while we are washing hair. And we shouldn’t drop litter into the river and so on.

It’s our duty to try our best to protect and save water. And don’t forget that if we don’t save water, the last drop of water will be our tear

Water is very important to us. We can’t live without water. But the drinking water is leand less. Because we waste a lot of water in our daily life. And some of us often throw rubbish into the rivers. So the rivers are polluted seriously.

It’s our duty to save water, we must do something to save water. For example, we shouldn’t pour waste water into the rivers and we should pick up litter around us.

If we don’t save water, the last drop of water will be our tear

How to protect the environment?

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

如何保护环境?

现在，越来越多的人意识到保护环境是必要和重要的。同时，也有一些人不`不注意卫生，他们可以`停止乱扔垃圾垃圾随便或随地吐痰的时候。此外，还有一些工厂经常砍伐树木，排放的化学物质和脏水。这引起了诸如温室效应等问题。如果他们天天这样做，我们的生活会变得很困难，所以我们必须阻止他们。为了阻止他们，我们可以提出公益广告，并告诉他们破坏环境的危害，所以我们可以从现在开始做一个美好的生活。

Dear Miss Liang,

亲爱的梁老师：

您好!我写信是想要感谢你为我做出的努力。在你的帮助下，我在学习上取得了很大的进步。一年前，我的学习成绩很差，我不想再学习了，但是你从来没有放弃我。你告诉我我很聪明。只要努力，我一定很棒。近年，你很关心我的学习，帮了我很多。当我犯错的时候，你总是指出错误并帮我更正。现在，我的学习比以前好多了，我想向你表达我的感激。祝您一切顺利。

人类的生存与发展离不开环境，然而，人类在谋求自身的生存与发展的同时，不断地将生态破坏和环境污染带给地球家园。

人类破坏环境的作文一

灰椋鸟生活在森林里，它们过得很幸福，可是灾难降临了-

一座座工厂建立在这片森林的小河边，把污水排进水里，致使小河变得肮脏不堪，动物们喝不到清水，一个个搬家了，可灰椋鸟们却没走，因为它们觉得森林是它们的家，一定要保护好家。

一个年长的灰椋鸟说：要保护森林一定要有力量，可我们这么小，哪来的力量啊？鸟们陷入了沉思。突然，小鸟果果说出了一个好办法，它说：我们灰椋鸟总是帮人类消灭害虫，如果我们停止吃虫，让虫子繁殖下去，看他们怎么办？这个主意好！灰椋鸟们齐声说。

接下来的几天里，由于小鸟们停止吃虫，虫类迅速繁殖，连人都控制不住了，市长连忙让人调查。过了几天查出结果后，市长想：连鸟都知道要保护环境，我们人类怎么不知道呢？市长立刻下令说：立刻拆了森林的工厂，并让工厂里的人个植十棵树，来表达我们的歉意，如有违令者，将他关进大牢！

过了一年后，这里就变成了动物的家园，它们快乐的生活在这里，而这座城市也变得犹如世外桃源一样了。

人类破坏环境的作文二

现在科技发达了，地球上的资源也应此遭到了严重的破坏。

现在地球上有两大严重的污染：一是大气污染，其二是水污染。先说说汽车废气污染吧！

由于现在科学发达了，随便在那里都能看见大大小小的汽车，自然而然空中的汽车废气也在横行霸道了。地面上生长的花草树木由于不被人类珍惜也变得稀少了。汽车废气没被吸收到的，有的会直接危害人类让人类生病甚至死亡；有的还会升上天空，与什么有毒气体混合(这里面学过，所以情原谅。)然后变成有巨大破坏性二氧化硫，之后二氧化硫慢慢地升上臭氧层，把臭氧层变得非常稀薄，强烈的阳光猛烈的直射到地面上，使地球搞得生灵涂炭，鸡飞狗跳，大海干枯，到处都是干旱，到处都是乞讨的人，大的上一片哭爹喊娘的声音。

还有一大污染就是水污染：我们在小河里，江里，大海里。都可以看到垃圾的身影，这些垃圾不是天然的，也不是因为河水变质而形成的，是人类随意丢弃的。也正因为这小小的垃圾才污染了一条河，一条江，甚至大海。虽然人们修了一些污水处理厂，一些地方的污水被制理了，变得山清水秀，环境也涣然一新了。但是这还是治标不治本呀！就算现在污水被全部治理了，但是人类还是会旧戏重演的。

有一句名言是说： 先天下之忧而忧，后天下之乐而乐 可是我们是 先天下之乐而乐，后天下之忧而忧 呀！那些只顾贪图享乐的人啦！快性过来吧！我们身边的环境需要我们来保护！我们的地球妈妈需要我们共同爱戴！

人类破坏环境的作文三

在一个美丽的大森林里，生活着许多动物。大树伸出它的双臂就像一把巨大的伞，小动物们在树下乘凉、快乐的玩耍，真像生活在一个绿色的世界。可不久，一些人们来到森林里，开始砍伐树木，一棵棵的大树被砍到了。就这样，过了两个月，原来茂盛的森林成了光秃秃的一片。随后就刮来了一阵沙尘暴，由于树木被砍光了，无遮无掩，慢慢的就形成了一片沙漠。森林里的动物们没法生活，只好离开这里，四处流浪。

去年，小鸭子和爸爸妈妈出去游玩，今年，它兴冲冲的回来，可是一切都变样了，再也找不到自己的家了，也找不到熟悉的伙伴。

突然，小鸭子看见一只小乌龟，就问道：“我们的好朋友都到哪里去了？”小乌龟说：“没有了树木，成天刮风，没有干净的水喝，没有食物吃，大家都四处逃生去了。小狗的呼吸快要停止了，到医院抢救了一夜才脱离危险，医生说就是因为环境不好才造成的。小狗一家搬到很远的地方居住了。更可怕的是，小龙虾和小鱼因为环境污染去世了！”小鸭子哭着说：“原来河水也被污染了，那我住哪呀！”

小鸭子自言自语地说：人类真的好可怕呀！我希望人类不要再破坏环境了，还给我们一个美好的家园！

这时，一位叔叔正要把抽完的烟蒂扔向花坛，我急忙赶过去说："叔叔，请爱护环境，不要随地乱扔烟蒂。"

At this time, an uncle was about to finish the cigarette butts into flower beds, I hurried over to say: "uncle, please take good care of the environment, do not throw cigarette butts. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

Inrecent years, tourism has been popular and played an important role in ournation’s economic growth. However, I am afraid that if tourism develops over,it will bring harm to the environment and give rise to many problems.

近年来，旅游业已经变得很流行，在我国经济发展中发挥了重要作用。然而，我害怕如果旅游业过度发展，它会给环境带来危害，并引发很多问题。

Thereare a few reasons accounting for my views and I would like to list three ofthem. One of the examples is that a large number of woods and other plants werereplaced by all kinds of accommodation facilities or scenic spots. Thatdefinitely breaks the ecological balance of these areas and destroys thenatural beauty of the scenic spots. Worse still, more pressure has been placedenvironment protection in that many tourists left their garbage in the scenicspots. In addition, over-developed tourism will occupy large numbers offarmland and lead to the shortage of the land.

我想列出其中三个可以解释我观点的几个理由。其中一个例子是大量的森林以及一些其他的植物被各种住宿设施或风景名胜区替代了。那肯定会打破这些地区的生态平衡，破坏风景名胜区的自然美。更糟的是，环境保护已经面临更大的压力了，因为许多游客在离开景点的时候把他们的垃圾丢在景点里。此外，过度开发旅游业会占用大量的耕地，导致土地短缺。

Ina word, tourism will be harmful to our environment if it is over development.Thus, I do not advocate that we development tourism without considering theenvironment. And we should keep the balance between tourism development andenvironment protection so that we can achieve the sustainable developmentbetween our nation’s economy and the environment.

总之，如果过度开发旅游业会对我们的环境有害。因此，我不同意在没考虑环境问题下就开发旅游业。我们应该保持旅游开发与环境保护之间的平衡，使我们能够在我们国家的经济和环境之间实现可持续发展。

[旅游过度开发对环境有害为题的英文作文

德国杜塞尔多夫的机器制造者林德曼发明了使废品能够重新利用的技术。新工艺的主要设备就是一部垃圾压力机，在这部机器里，通过高压和磨擦生热使垃圾的分子结构发生变化。经过机械和高温处理，垃圾中所含的较高的塑料成分(例如粉碎后的旧汽车部件)可以变成“煤饼”。这些作为回收物资的“煤饼”可以用于高炉或化铁炉，也可以用于垃圾焚烧设备或者存放起来，不污染环境。

压成“煤饼”的做法可以使过去的垃圾量减少到1/7，而且“煤饼”还可以继续被加工成颗粒或粉末。用这样的“煤饼”做成的“煤末”可以代替真正的煤末，热值同褐煤的热值不相上下。

操作方法：在双螺旋压力机里装填轻垃圾，这些垃圾是经过粉碎机处理、把金属回收后剩下来的。这些垃圾里包括橡胶、玻璃、养料、汽车座垫、泡沫塑料、门窗护板、污物等。在压力机里对这些起东西进行处理时，不仅仅是起到压制作用，而且这些东西还完全混合在一起。这样一来，这些东西便达到了相同的燃点。

Will Tourism Bring Harm to the Environment?

Tourism has developed by leaps and bounds in the past decades in the whole world. Therefore, the issue of whether the tourism will bring harm to the environment is becoming a matter of concern. As for me, I hold that the tourism does more harm than good to the world.

In the first place, the more places we travel to , the more pressure will be added to the environment. Take Dunhuang as an example, the greatest scourge these days comes from the tourists who swarm here by the busload , bring destructive amounts of carbon dioxide and moisture into the caves along with their eagerness for a glimpse of ages past .

Secondly, It has become fashionable for travelers to drive a private car to the place they want to . In this case ,a large number of cars are mushroomed in the road and it cause twice as much as air pollution .At this speed ,we may live in a world which is full of dirty air instead of fresh air.

In sum , although tourism is playing an indispensable role in the society , I still believe that we`d better try to limit its speed according to the harm that brings to the environment.

自然环境是人类生存、繁衍的物质基础；保护和改善自然环境，是人类维护自身生存和发展的前提。这是人类与自然环境关系的两个方面，缺少一个就会给人类带来灾难。

我们生活的自然环境，是地球的表层，由空气、水和岩石(包括土壤)构成大气圈、水圈、岩石圈，在这三个圈的交汇处是生物生存的生物圈。这四个圈在太阳能的作用下，进行着物质循环和能量流动，使人类(生物)得以生存和发展。

据科学测定，人体血液中的60多种化学元素的含量比例，同地壳各种化学元素的含量比例十分相似。这表明人是环境的产物。人类与环境的关系，还表现在人体的物质和环境中的物质进行着交换的关系。比如，人体通过新陈代谢，吸入氧气，呼出二氧化碳；喝清洁的水，吃丰富的食物，来维持人体的发育、生长和遗传，这就使人体的物质和环境中的物质进行着交换。如果这种平衡关系破坏了，将会危害人体健康。

人类为了生存、发展，要向环境索取资源。早期，由于人口稀少，人类对环境没有什么明显影响和损害。在相当长的一段时间里，自然条件主宰着人类的命运。到了"刀耕火种"时代，人类为了养活自己并生存、发展下去，开始毁林开荒，这就在一定程度上破坏了环境。于是，出现了人为因素造成的环境问题。但因当时生产力水平低，对环境的影响还不大。

到了产业革命时期，人类学会使用机器以后，生产力大大提高，对环境的影响也就增大了。到本世纪，人类利用、改造环境的能力空前提高，规模逐渐扩大，创造了巨大的物质财富。据估算，现代农业获得的农产品可供养五十亿人口，而原始土地上光合作用产生的绿色植物及其供养的动物，只能供给一千万人的食物。由此可见，人类已在环境中逐渐处于主导地位。

但是，严重的环境污染和生态破坏也随着出现在人类面前。大气严重污染，水的资源空前短缺，森林惨遭毁灭，可耕地不断减少，大批物种濒临灭绝，人类赖以生存的自然环境正处在危机之中。日益恶化的环境向人类提出：保护大自然，维持生态平衡是当今最紧迫的问题。
