高二英语作文：河流污染RiverPollution【19篇】

When you are reading something in English, you may often come across a new

word. Whats the best way to know it?

You may look it up in an English-Chinese Dictionary. It will tell you a lot

about the word, the pronunciation, the part of speech, the Chinese meaning and

also how to use this word.

But how can you find it in the dictionaiy both quickly and correctly7

First, all the English words are arranged in thealphabetical order. In the

dictionary you can first see the words beginning with the letter A, then B, C,

D, E,... That means, if there are two,words "desert" and "pull", "desert" will

be certainly before "pull". Then if there are two words both beginning with the

same letter, you may lo0k at the second letter. Then the third, the fourth, ...

For example,"pardon" is before "plough", "judge" before "just",etc.

Do you understand how to look up a word in dictionary?

The dictionary will be your: good friend. I hope youll use it as often as

possible in your English learning.

Knowledge can be acquired from many sources. These include books, teachers and practical experience, and each has its own advantages. The knowledge we gain from books and formal education enables us to learn about things that we have no opportunity to experience in daily life. We can study all the places in the world and learn from people we will never meet in our lifetime, just by reading about them in books. We can also develop our analytical skills and learn how to view and interpret the world around us in different ways. Furthermore, we can learn from the past by reading books. In this way, we won’t repeat the mistakes of others and can build on their achievements.

获得知识的来源有很多。这些包括书籍，教师和实践经验，每个人都有自己的优点。知识从书本上及正规教育使我们知道在日常生活中没有机会经历的事情。我们可以研究世界各地的人学习我们不会在我们的有生之年遇见，只在书上读到的人。我们也可以培养分析的技巧，并学习如何看待和理解我们周围的世界以不同的方式。此外，我们可以从过去中学习，通过阅读书籍。这样，我们就不会再重复别人的错误，并且能够以他人的成就。

Practical experience, on the other hand, can give us more useful knowledge. It is said that one learns best by doing, and I believe that this is true, whether one is successful or not. In fact, I think making mistakes is the best way to learn. Moreover, if one wants to make new advances, it is necessary to act. Innovations do not come about through reading but through experimentation. Finally, one can apply the skills and insights gained through the study of books to practical experience, making an already meaningful experience more meaningful. However, unless it is applied to real experiences, book knowledge remains theoretical and, in the end, is useless. That is why I believe that knowledge gained from practical experience is more important than that acquired from books.

实践经验，另一方面，可以给我们更多有用的知识。这是说从做中学的效果最好，我相信这是真的，无论一个人成功与否。事实上，我认为犯错是最好的学习方式。此外，如果想要有新的进展，这是必要的行动。创新不能只靠阅读是实验。最后，我们可以将所获得的技巧和见解通过书籍来实践经验的研究，使得原本有意义的经验变得更有意义。然而，除非它应用于实际经验，书本知识是理论和，最后，是无用的。那就是为什么我会认为从实际经验中获得的知识比从书本中学到的更重要。

In this world there are many difficulties, overcome the eat to the success of candy, failed to eat very sour acid pears, in when I was three years old, has tasted the sweets of success.

Remember when I was three years old is four wheeled bike ride, then see other children on two wheels of the bicycle, I also want to ride. But in the heart of demons how also wont disappear, always afraid of hurt, afraid of ke is hurt. Mom and dad gave me great encouragement, and finally the two small wheeled off and ride up and not focus, always stagger, two feet without leaving at the same time. Havent contact for a while, I like frustrated the ball, pursed mouth. Mom and dad to see me so soon discouraged, told me a lot of truth, I also dont listen. Finally mom and dad use a meter, let me quickly learned to ride a bike.

Mom and dad pushing his bike out, riding up and said to me: "tingting, my mother and I want to ride a bike to go out to play, goodbye!" I have a look at mom and dad to go and ride a car chase, said: "you dont go, wait for me." This is mom and dad just stopped and looked at me and smiled. I immediately stopped, hugged daddy, said to him: "dad, I can ride a bike."

So, I learned to ride a bike, and after I hard practice, I mastered the skills in less than a week. Our family bicycle went out to play.

"Difficulties like spring, you weak it is strong. Difficulties like spring, you strong it is weak."

I through that finally understand this truth, to insist, can not fall by the wayside. Must eat to the success of sweets!

这个世界上有许许多多的困难，克服了就吃到了成功的糖果，失败了就吃到很酸的酸梨，在我三岁时，就尝到了成功的糖果。

记得我三岁时骑的是四个轱辘的自行车，那时看到别的小朋友都起两个轮子的自行车时，我也很想骑。可是心中的心魔怎么也消失不了，总是怕摔着，怕磕疼了。爸爸妈妈给了我很大的鼓励，最后把两个小轱辘卸掉了，骑上去没有重心，总是东倒西歪，两只脚没有同时离开地的时候。还没联系一会儿，我就像泄了气的皮球，撅起了嘴巴。爸爸妈妈看我这么一会儿就泄气了，给我讲了好多道理，我也听不进去。最后爸爸妈妈使用一计，让我很快学会了骑车。

爸爸妈妈也把自己的自行车推了出来，骑了上去并对我说：“婷婷，我和妈妈要骑车出去玩了，再见啦!”我一看爸爸妈妈要走，一边骑上车追，一边说：“你们别走呀，等等我。”这是爸爸妈妈才停下来，看着我，会心的笑了。我立刻停了下来，抱住了爸爸，对他说：“爸爸，我会骑车了。”

就这样，我学会了骑车，经过我刻苦的练习，我不到一个星期就掌握了技巧。我们一家子骑车出去玩了。

“困难像弹簧，你弱它就强。困难像弹簧，你强它就弱。”

我通过那件事终于明白了这个道理，做事要坚持，不能半途而废。一定要吃到成功的糖果!

Recently, the weather is always foggy, I desire to go out to play always goofing around by the weather. By reading the newspaper, I see this kind of weather is fog, its because suffer from serious air pollution is formed under certain conditions. The air quality around us, it seems, really worrying wow.

I learned from the newspaper that the recent most region of east-central China shrouded in a fog, there was a joke, "the furthest distance in the world is - youre standing in front of me, but I cant see you!" Miles "haze" fell to the general public had panic, mom always said to me, the air pollution is too serious, cant go out. Many pedestrians travel when put on a mask, in order to cope with poor air quality, but always let a person feel breath.

The first two heaven like a snow, full of expectation to the snowfall, thought the snow fog haze will dissipate. After a haze in the mist, however, in many places the air quality is worse. Newspaper has reported the effects of the cause of the bad weather, let I also attention of fog is increasing day by day.

In view of the fog weather continued, around a lot of measures to improve air quality, such as restrictions on vehicle travel, elimination of old vehicles, oil to gas generation and so on. But, I think, this is not the ultimate, government departments should fundamentally to solve the related problem.

Purify air, improve the environment, urgent! Let us all act, but also a clean world!

近期，天气总是雾蒙蒙的，我想出门玩耍的愿望总是被这鬼天气给搅和了。通过阅读报纸，我明白了这种天气就是雾霾，它是因为空气遭受比较严重的污染才在一定的条件下形成的。看来，我们身边的空气质量真令人堪忧哇。

我从报纸上得知，近期我国中东部大部分地区笼罩在一片雾霾之中，有人戏言：“世界上最远的距离是——你站在我面前，我却看不到你!”十里“霾”伏让广大市民心生恐慌，妈妈总是对我说空气污染太严重了，不能出门。许多行人出行时都戴上口罩，以此来应对恶劣的空气质量，却总让人有喘不过气的感觉。

前两天降过一场雪，大家对这次降雪充满期待，以为雪后雾霾就会消散。然而雪后雾霾依在，不少地方的空气质量更差了。报纸频频报道这种恶劣天气产生的原因带来的影响，让我也对雾霾的关注度日益提高。

针对持续的雾霾天气，各地出台不少措施来改善空气质量，如限制车辆出行，淘汰老旧车辆，以气代油等等。可是，我想，这还不是根本，政府部门应该从根本上着手解决相关问题。

净化空气，改善环境，刻不容缓!让我们大家都行动起来，还世界一片洁净!

Pollution around us

In recent years our life is becoming better and better. But our environment is becoming worse and worse. Its very bad for our life. Now many people have air-conditioners and cars, they produce (give off ) waste gas. More and more trees are being cut down. There are so much sand on the earth (leaving only sand ) . We often see factories pour waste into rivers or lakes. Water in the river is quite dirty. We havent enough clean water to drink in cities. Now we are in danger. Its very necessary and important to protect the environment well. I think if everyone tries his best to protect the environment, the world will become much more beautiful , and our life will be better and better .

我们周围的污染

近年来我们的生活越来越好。但是，我们的环境越来越糟。它对我们的生活很糟糕。现在很多人都有空调和汽车，他们生产的（出）废气。越来越多的树被砍伐。有那么多的沙子在地球（只留下沙）。我们经常看到工厂把废水倒入河流或湖泊。河里的水很脏。我们没有足够的干净的水的城市。现在我们有危险。这是非常必要和重要的保护好环境。我想，如果每个人都尽自己最大的努力去保护环境，世界将变得更加美丽，我们的生活会越来越好。

人的爱好多种多样，有新奇绝妙的，有平淡无奇。我的爱好虽不新奇，但广泛得连父母都时常感叹。而在这众多的爱好之中，我还是对读书情有独钟。

爱看书还得从七年前说起。那是贪玩的我并不怎么爱看书，但有一次，从玩具堆中发现了一本被翻开的书。好奇心促使我看了下去。一下子，我马上被书中那精美的插图与那精彩的内容给吸引了。而且一发不可收拾，从此，我就爱上了读书。

长大后，懂事的我越来越爱看书了，每天都要看，少看一天都不行，成了一个不折不扣的“小书虫″。为此，我还闹出了笑话呢!记得有一次，妈妈让我烧水，烧水时，我便拿起一本书，津津有味地品读书中的精彩内容，看得忘乎所以。结果，水壶被烧坏了，搞得满屋子烟。这时，妈妈看见了，就问我怎么回事。我这时才回过神来。“糟糕!我的水呢?”妈妈见我这副模样，无可奈何地唉声叹气：唉!你这个小书虫!我提醒过你多少次了……’’

虽然我因为看书误了事,但我仍然爱读书.因为从书中,我学会了许多知识,悟出了许多道理,认识许多朋友：丑小鸭、快乐王子、孙悟空、鲁迅、冰心、爱迪生……读书还使我的作文水平提高了不少呢!

现在,书成了我每天必需的营养品,生活中没有书,就好像鸟儿没有翅膀，生命没有书,就好像生活没有阳光,书是人类进步的阶梯，书是知识的源泉!

我爱读书,因为读书使我的生活丰富多彩，使我的生命充满阳光!

Last year, I went to Guang Zhou in the summer vacation. I felt so excited, it took me about four hours to get there. In the daytime, the air was so stuffy and the sun was so hot, so my friends and I decided to take a rest in the hotel. When the sun almost got down, we started to go on the street, the first thing was to find something to eat. There were so many delicious snacks, we had no idea which to eat, so we planed to eat as much as we could. I found myself couldn’t stop eating, the food was tasted. After we finishing eating, we started to go shopping.Guang Zhou is famous for the foreign trade, its clothes are fashionable and cheap. We went to the shopping street, trying on all kinds of clothes, at last, we bought many clothes. This trip is so unforgettable to me.

去年暑假，我去广州旅游。我感到很兴奋，我花了大约四个小时到那里。白天，空气很闷，太阳很大，所以我的朋友和我决定去旅馆休息。当太阳将要下山了，我们开始逛街，第一件事就是找东西吃。街上有很多美味的小吃，我们不知道吃什么好，因此我们计划尽可能多吃。我无法停止下来，食物太美味了。吃完以后，我们开始购物，广州的外贸很出名，衣服时尚，价格便宜。我们去了购物街，试了各种各样的衣服，最后，我们买了很多衣服。这趟旅程对我来说是很难忘的。

My winter vacation

During the winter vacation, nothing is different for my life. I wake up 11 oclock Am everyday, after a washing, I have a good lunch with my parents. Next I play computer games till the time to have supper. After have dinner. I go on playing till 2 oclock Am, and then go to sleep with tired. This is one dull day of my winter vacation.

But I havent bored all the time. Sometimes I read the books, sometime I listen to the music or the radio in the bed, because it was very cold outside and snowy all the day. And I also meat some of my good friends during the vacation, we have a very long talk about the life of each other in the past year and play table tennis tegether. And I watched the spring festival party of the CCTV in the last seconds of the 2004 year! I think this is the thing most people of china doing at that time.

A cigarette after a meal, happy as the fairy. "The other words right, but for a long time, a cigarette for you it is not enough.

Smoking increases the risk of cancer, also can let you lungs become yellow, if is pregnant women smoke, belly child is very poor, will suffer because you smoke. Have a friend call you smoke, please say "no", not easy to accept each other, make oneself sink down. The disadvantages of smoking too much too much, smoke so expensive, how do you willing to spend money to buy? Smoke a pack a day, a year, it will all be spent a lot of yourself or for her to earn the money.

If I were you, I would put the money to buy cigarettes, over the years, you can buy more valuable items. If your boyfriend is a dazed and confused love smoking guy, please advise him not to smoke any longer, if not be persuaded, also asks you to slowly, quietly leave him. Also good smoke, smoke can let you have a lot of spirit, but it is the burden, the consequence is very serious, people stop smoking, we should also be a good happy for him.

Today smoking is a lot of, if your mom and dad, will smoke, please also advise them!!!! Secondhand smoke also is very bad.

饭后一根烟，快乐似神仙。”这句话说得没错，可是抽久了，对你来说一根烟根本是不足够的。

抽烟得到癌症的机率提高，也会让你肺部变黄黄的，如果是孕妇抽烟，肚子里的孩子很可怜，会因为你抽烟而遭殃。有朋友叫你抽烟，请一定说“不”，不要容易接受对方，使自己向下沉沦。抽烟的坏处实在太多太多了，烟那么贵，你怎么舍得花钱去买呢?一天一包，抽一年的话，就会白白花掉很多自己或爸妈赚来的血汗钱。

如果是我，我会把那些买烟的钱省下来，过了好几年，就可以买更有价值的物品了。如果你的男朋友是个年少轻狂爱抽烟的家伙，请劝劝他不要在抽下去了，如果不听劝，也请你慢慢的、默默的离开他。烟也有好处，烟可以让你很有精神，不过它造成的负担、后果很严重，戒烟的人，我们也应该好好的替他开心。

如今抽烟的人还是很多，如果你的爸爸、妈妈，也会抽烟，也请你劝劝他们吧!吸二手烟也是很不好的。

Times are changing day by day. Doing the shopping is easier. Most people

are better-dressed and they enjoy modern life.

Girls are changing, too. There are many differences between the older and

younger generations.

I know a twelve-year-old girl, who, to my surprise, has little time to

play. She told me that she dreamt of being a dancer, so she must learn to dance,

play music and so on. Sometimes, she is out of breath under such pressure, but

she can’t stop because modern life is busy.

In addition, I find those girls know more and more. Although they are

little girls, they know how to dress fashionably. Sometimes they look older than

their age, though.

As an older female, I realize that compared with the modern girls, my

generation is less well-educated and takes part in fewer leisure activities. I

realize that we don’t make full use of our time the way they do. Therefore, we

should try our best to value our time and pursue our dreams.

Confident, proud and energetic, modern girls represent new times.

Last week, my English teacher gave us a task, she asked us to form a small group, each group was made up of five students, the groups need to do a research, it is about how much people know about foreign country. In my group, there are three girls and two boys, at first, we did not know what to do, then I suggested our group take the cooperated work. As I and the girl are good at writing paper, so the two of us decided to design the questions, and the other three students are so active, so they like to ask people the questions. The research went go so well, we finished it in two days, thanks to the teamwork, we did well on the task. The teacher praised my group, I have learned the importance of cooperation, since then, I will considerate other people’s feelings.

上周，我的英语老师给我们布置了一个任务，她叫我们组成一个小组，每个小组由五个学生组成，需要做一个调查，那是关于人们对西方国家了解多少。在我的小组里，有三个女生和两个男生，刚开始，我们不知道如何去做，然后我建议小组采取团队合作。由于我和一个女孩擅长写作，因此我们两个决定去设计问题，另外的三个同学很活跃，因此他们喜欢去人问题。调查进行得很顺利，我们在两天内就完成了，多亏了团队合作，我们的任务完成得很好。老师赞扬了我的团队，我已经学到了合作的重要性，从此以后，我会考虑别人的感受。

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 f 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.

I was born in an ordinary family, but the love my parents gave me made me

feel that I was the happiest girl in the world. Before I went to middle school,

my parents decided to let me live in the hometown, where I spent the good time.

I was surrounded by green trees and clean water. Every day, I would play funny

games with my friends. When I went to middle school, I left hometown and moved

to the city to live with my parents. I needed to focus my attention to study.

Every night, my father would check my homework and if I had questions, he would

help me to solve them. My mother always made delicious dessert for us. When I

finished homework, we ate them together and talked happily. I had the good time

of my childhood.

With the development of science , more and more people are confused that whether it is good or bad to make robort. Are roborts going to take place of human beings.

Every coin has two side. Robort can be good to our society and life. At the same time,it also have some bad effect on our life.In my opinion, the advantages of robort are much more than the disadvantage of roborts.

First, roborts make our life more convenient. We can do many thing that we didnt have the ability to do in the past by using roborts.That makes our life more effective.

Second, roborts can be used in industry produce. Factories can reduce the cost of prodution by using roborts. Roborts do not need to eat and they will not be ill. Thats very good for producing goods.

Third,roborts can save more people when disaster happens. Because they cant feel pain and they can save more people without feeling tired.

In a word, the world is changing .We should also change our thought to accept roborts to become part of our life . That can make our life more colorful.

随着科技的发展，越来越多的人都感到困惑，是好是坏机器人。是机器人将取代人类。

每个硬币都有两面。机器人可以很好的为我们的社会和生活。同时，它对我们的生活也有不好的影响。在我看来，对机器人的优点远大于缺点的机器人。

首先，机器人使得我们的生活更方便。我们能做的，我们没有做过去用机器人的能力，很多事情，使我们的生活更有效。

其次，机器人可以用于工业生产。工厂可以通过降低生产成本的机器人。机器人不需要吃饭，他们会不会生病。这是非常好的生产商品。

第三，机器人可以挽救更多的人，当灾难发生时。因为他们不能感到痛苦，他们可以拯救更多的人而不觉得累。

总之，世界在变化，我们也应该改变我们的思想，接受机器人成为我们生活的一部分。这可以使我们的生活更加丰富多彩。

暑假里，我看了一本有趣的童话故事书。

During the summer vacation, I read an interesting book of fairy tales.

我喜欢看这本书，因为这是我看过的童话书中最好看的一本书，我反复看了三、四遍，我对这本书是爱不释手。

I like to read this book, because it is the best I have seen the book of fairy tales in the book, I read it three or four times, I was one of this book.

这本书大概描写的是：有四个孩子无意中进入了一个衣橱，来到了一个叫“那尼亚”的地方，那里由一个女巫统治着，女巫把“那尼亚”变成了冬天。孩子们和一头狮子打败了女巫，春天回来了，孩子们也当上了国外和女王。许多年后，孩子们都长大了，他们追捕一头仙鹿时，无意中回到了衣橱里。

This book is about it: there are four children inadvertently entered a wardrobe, and came to a place called "Narnia", where a witch to witch ruled, "Narnia" into winter. The children and the lion beat the witch, spring is coming, the children also became a foreign queen. Many years later, the children have grown up, they pursue a fairy deer, inadvertently back in the closet.

我看完这本书后，想到了另一个结尾，我觉得这个结尾更适合这本书，就是：至今，衣橱还在那个人家里，你不信就去看看吧!

I read this book, the thought of another end, I think this is more suitable for the end of the book, is still in the closet:, family, you do not believe it to have a look!

In my opinion, the schoolwork now being assigned to high school students is

too heavy. While it is true that students need to study, they need other things

as well if they are to grow into healthy and well-rounded adults. High should be

allowed more time for play. Plying is not wasting time, as some think. It gives

them physical exercise, and also exercise their imagination. Which tends to be

stifled by too much study. Finally, the pressure put on high school students by

excessive schoolwork can cause serious stress, which is unhealthy physically and

mentally. I do not advocate the elimination of schoolwork. I do think, however,

that a reduction of the current heavy load would be beneficial to students and

to the society as a whole.

I have a sister. Her name is Alice . She is one year old. She has short hair. She has a fat face. It looks like a big red apple. She has big eyes and a small mouth. She has only one tooth, but she can eat cookies. Her arms and legs are fat, too. But she can crawl very fast on the floor.

My sister is very naughty. She doesn’t sleep at night but sleeps at daytime. So my mother is tired to take care of her. She always crawls here and there, sofa, bed, chair, everywhere she likes to go. She likes to play with the toys. Bricks are her favourite. She likes to make different shapes with the bricks. Sometime it’s a house, sometimes it’s a bus. I think she is a smart girl. She likes to play with me. She likes my story-telling. She always asks me to tell stories for her.

There is a cartoon “Present Sheep and Mr. Wolf” on TV. My sister likes it so much. Every time when I turn on the TV, she always says “present sheep” to me, asks me to watch the cartoon. And every time she hears the theme song of the cartoon, she will sing and dance on the floor. Actually she can not sing and dance, she just shakes her little body to show us she likes it very much. She is so cute.

My sister is smooth-tongued. She likes to call me “sister”, call my dad “daddy”, call my mom “mummy”. She often call us many times a day.

In my eyes, my sister is naughty, lovely and smart. I like her.

Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.

However, it may be that we still have a long way to go before we have a clean world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution
