高一关于环保的英语作文（实用20篇）

suppose someone gave you a pen - a sealed, solid-colored pen. you couldnt see how much ink it had. it might run dry after the first few tentative words or last just long enough to create a masterpiece (or several) that would last forever and make a difference in the scheme of things. you dont know before you begin. under the rules of the game, you really never know. you have to take a chance!

actually, no rule of the game states you must do anything. instead of picking up and using the pen, you could leave it on a shelf or in a drawer where it will dry up, unused. but if you do decide to use it, what would you do with it? how would you play the game? would you plan and plan before you ever wrote a word? would your plans be so extensive that you never even got to the writing? or would you take the pen in hand, plunge right in and just do it, struggling to keep up with the twists and turns of the torrents of words that take you where they take you? would you write cautiously and carefully, as if the pen might run dry the next moment, or would you pretend to believe that the pen will write forever and proceed accordingly?

and of what would you write: of love? hatred? fun? misery? life? death? nothing? or everything? would you write to please just yourself, or others, or yourself by writing for others? would your strokes be tremblingly timid or brilliantly bold? fancy with a flourish or plain? would you even write? once you have the pen, no rule says you have to write. would you sketch? scribble? doodle or draw? would you stay in or on the lines, or see no lines at all, even if they were there? or are they? theres a lot to think about here, isnt there?

A Polluted Environment

Environmental pollution is a serious social problem. It poses a terrible threat to men’s health.

The atmosphere is filthy. The air is thick with dust and burnt oil. Dark smokes are being emitted from chimneys, and choking fumes are being

released from numerous vehicles. Stay a little while in a big city, then wipe your forehead with your handkerchief, it is black. Hang out your

washing on the line to dry, you will have to wash again. Garbage is left to accumulate in unsanitary heaps that attract flies and give off bad smell.

Nor is the pollution confined to air and land. Large quantity of sewage and chemical waste are dumped daily into rivers, lakes and the sea,

which kills millions of fish. Noises coming from honking cars, rumbling machines and broadcasting loudspeakers may make a person nervous and

irritable, even drive him crazy.

Environmental pollution is responsible for many diseases that are disabling, or bringing death to human beings.

In short, let’s take good care of our mother globe, not only for the well-being of ourselves, but also for that of our future generations.

Ah! Christmas morning! Children like to wake up early while its still dark and sneak into the living room to check the presents----find any with their name on it, shake them to guess whats inside, and then maybe theyll go back to bed and pretend they are still asleep when their parents come to wake them with a "Merry Christmas!"

But almost no one I know gets completely dressed or eats a regular breakfast first thing Christmas morning. They just put on a robe or wear their pajamas and go to see whats under the Christmas tree. Some Christian families have a tradition of reading the Bible story of Jesus birth. Maybe its to remind the children that Christmas is Jesus birthday.

Someone will begin to take the presents out from under the tree, see whose name is on the package, and then pass them around. Some families wait until all the presents have been given out before opening any of them, while others open each one as it comes to them. There are many "thank you" to the ones who gave the gifts, new clothes are tried on to see if they fit, and of course the most interesting toys will immediately be played with.

Usually among the Christmas gifts will be some especially delicious candy or cake or cookies which everyone tastes. These sweet things may be the only breakfast many people eat Christmas morning. After the gifts have been opened, the room will be tidied up except where the children are playing with their toys. Everyone will wash and get dressed for the day.

Some people may go to a Christmas morning church service around ten oclock if their church didnt have one on Christmas Eve. But most people will just watch TV. Well, most men will. The children may play outside or inside with their new toys, but the mothers will be in the kitchen preparing Christmas Dinner.

啊!圣诞节的早晨!孩子们喜欢早起,它仍然是黑暗和溜进客厅去检查礼物——找到任何与他们的名字,动摇他们猜里面有什么,然后他们可能会回到床上,假装他们是还在睡觉当他们的父母叫他们“圣诞快乐!”

但是我几乎没有人知道会完全打扮或吃普通的早餐圣诞节早晨的第一件事。他们只是穿上长袍或穿睡衣去看圣诞树下会有什么。一些基督教家庭的传统阅读圣经耶稣诞生的故事。也许是提醒孩子们,圣诞节是耶稣的生日。

有人会开始把礼物从树下,看到包装上是谁的名字,然后通过周围。一些家庭等到已经给所有的礼物之前打开其中任何一个,而其他人打开每一个涉及到他们。有很多“谢谢”的人给了礼物,新衣服试穿,看看是否合适,当然最有趣的玩具就会玩。

通常会在圣诞礼物一些特别美味的糖果、蛋糕或饼干,每个人的口味。这些甜食可能是唯一早餐很多人吃圣诞节的早晨。礼物被打开后,会整理房间除外孩子们玩他们的玩具。每个人都会洗干净,穿好衣服。

有些人可能会去一个圣诞节的早晨教堂服务大约10点钟如果他们的教会没有一个在圣诞前夜。但大多数人只会看电视。嗯,大多数人的意愿。孩子们可能会在外面玩或在他们的新玩具,但妈妈会在厨房里准备圣诞晚餐。

Advertisements are forcing their way into people’s lives. People refer to advertisements in their daily lives because they are consumers. The advertisers are usually manufacturers, retailers and salesmen. Their merchandise needs to be advertised to bring it to the attention to the customers. Thus nearly every product is advertised in some way. To a large extent, good advertising leads to success while bad advertising can mean failure.

There are many ways to advertise and ‘ads’ come in different forms. Newspapers carry advertisements. Some products are publicized on TV and radio which bring them into notice of a wide audience. Billboards also carry advertising. Advertising is a big industry now and many agencies have been set up to furnish a variety of forms.

However, advertising is not always truthful. A product is often misrepresented. The advertiser exaggerates the benefits of the merchandise he wants to sell. Thus, he misrepresents the truth. The consumer falls victim to such advertising. Millions of people have bought advertised products and have been dissatisfied with them。

Many years ago, when the online business first became popular among the

public. The manufacturers tried to make some slogans so as to catch more

customers. Then the day of November 11th was named the single day, and they gave

great discount. Today, it has become a shopping day.

There is no doubt that e-commerce is the future. With more young people

rely on the Internet, they get used to purchase online. Looked at the past five

years, November 11th gala has been famous around the world for the great profit

gained on that day. According to the report, the total income of e-commerce on

this gala surpasses the rest days of the year! What a surprise data.

The businessmen sense the great market potential and they advocate people

to make purchase on that single day, because there is great discount. If they

miss it, they will be regretful. With the successful marketing strategy, all the

people are so crazy about this gala. No one can resist the temptation, because

there is always something they want.

Since I was a little child, I had a dream that I wanted to be a doctor.

When I was little, I watched many TV series and movies about doctors. I thought

they were so great. Therefore, I made up my mind to be a doctor. In my opinion,

doctor is the people who can help patience get out of sickness and pain.I want

to be the person who can help others. However, being a doctor needs so much

professional knowledge and there is a long way to go. So I have to try my best

on my study and go to a good college.

Trees are important resources. They provide us with wood, which is not only an important building material, but also indispensable in making paper, furniture, matches and many other useful things. Without tress, we would perhaps still be living in caves, and our life would be very miserable.

Trees also do good to our environment. They not only make our world greener and more beautiful but also produce oxygen which makes the air we breathe fresher and better for our health. What’s more, trees help maintain ecological balance, which is very important to our survival.

Fortunately, trees, unlike other resources, can be “reproduced”. While coal and oil can be burnt up and exhausted, trees will never be used up because we can always plant new ones. And when we plant trees, we know that we are helping make our world richer, pleasanter, and more beautiful to live in. So let’s plant more trees.

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。

[自我介绍高一英语作文

在我们这个蔚蓝的地球上，每个生灵都有自己的家，森林是野生动物的`乐园，池塘是小鱼的小屋，天空是小鸟的天堂，而地球是我们人类与动植物共同的家园。地球给了我们水源与森林，给了给了我们清新的空气和食物。我们的美丽家园，从现在做起，是一件理所应当的事。

可这理所应当的事，我们人类又是怎样做的呢?听爸爸妈妈说，以前的地球到是处山清水秀，鸟语花香，人们可以自由地呼吸那使人心旷神怡清新的空气。可是现在，地球变成什么样了呢?人类对森林、水源毫不珍惜，慷慨大方的挥霍。一片片森林变成荒山，一条条大河污水横流。大量化学药品的滥用，造成一系列的生态灾难。据我所知，目前全世界的工厂和电厂每年排入大气中的二氧化碳有50亿吨;二氧化硫、碳氧化物等有害气体的排放量也相当大。

进入大气中的废气种类很多，已经产生危害而引起人们的注意的就有一百多种。废气进入大气层中，破坏大气原有的化学组织和性质，多少人因患肺癌而死，全球变暖使冰山融化，整个地球大量农作物随气候变化而减产，直接危险人类生存已不再是科学家的预言。我们看到，地球在哭泣，大气在燃烧。人类的一场又一场巨大的灾难，正在上演。

面对灾难，我们不能无动于衷，保护环境，人人有责!爱我们的美丽家园，从现在做起，我们现在虽然还只是小学生，不可能为全人类的环境作出特别大的贡献，但我们可以从身边的小事做起，从现在做起:

从保护我们居住的环境做起，我们可以关爱小区中每一棵树;从保护学校的环境做起,我们可以把教室的窗台摆满花草。同学们，我们是21世纪的主人，环保意识是现代人的标志。我们要有时代责任感，为美化环境净化环境作出我们应有的努力，"勿以恶小而为之，勿以善小而不为"，让我们共同努力，爱我们的美丽家园，从现在做起。——让我们的美丽家园，清风常拂绿柳，碧水永伴苍山!

The world we live in is becoming more and more intolerable because of environmental destruction. Bird flu and Sars are two typical examples that environmental destruction may threaten our life. Besides, forest destruction , water and air pollution result in decrease of planting land and unpleasant weather.

Serious as the problem seems, we can come up with some measures to deal with it. First of all, the authorities should adopt the policy of "sustainable development", and laws concerning environmental protection should be put into effect and enforced strictly just as our government has been doing.

What s more, every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment. In addition, planting trees helps improve and beautify the environment.

更重要的是，每个公民都应该认识到问题的严重性，并共同努力保护我们的环境。此外，植树有助于改善和美化环境。

Computer

You’ve probably known about computers your whole life. But computers have not really been around for very long. Computers started to become popular with big companies in the 1960s. Computers didn’t become widespread in homes and schools until the 1980s.

HOW DO PEOPLE USE COMPUTERS?

People use computers in many ways. Stores use computers to keep track of products and check you out at the cash register. Banks use computers to send money all over the world.

Computers help teachers keep track of lessons and grades. They help students do research and learn. Computers let you hook up to networks (many computers hooked together). They let you hook up to a worldwide network called the Internet.

Scientists use computers to solve research problems. Engineers use computers to make cars, trucks, and airplanes. Architects use computers to design houses and other buildings. The police use computers to track down criminals. The military uses computers to make and read coded messages.
