用英语描述水的作用(精品20篇)

Water is very important to us. If you dont have water for three days, you will die. We can use water for flowers, swimming, washing and many different things. We use it to cook, make electricity, and put out fires and so on. We use millions of liters of water every day.

水对我们很重要。如果没有水，不出三天，你就会死的。我们可以用水游泳，洗涤和做许多不同的事情。我们用它做饭，发电，和扑灭火灾等。我们每天使用数百万公升的水。

Do you know how does the water come to your home? It travels through water pipes. Some are long and wide but some are short and narrow. Then the water travels through the water pipes to the reservoirs. Then it travels through the water pipes to the river and to the special factories that purify the water. When the water is purified, we can drink it. Please dont leave garbage in the water on which we line, and keep the water clean.

你知道水是如何来到您的家吗?它穿越水管。有些是长而宽的，但有些是短而细的。然后通过水管到达水库。然后通过河流和专门用来净化水的工厂。当水净化后，我们可以喝它了。请不要丢垃圾到水中，因为水是我们的生命线，我们要保持水的清洁。

When I go to high school, our school has the rule to ask students to live

in the dormitory. Most students live with their parents before, so we all feel

excited and afraid of the group life. Luckily, I have three nice roommates. Soon

we become close friends. Living with others, we learn to do the house work, such

as everyone needs take turn to clean the floor, when we have something good to

eat, we will share with each other. The group life makes us have less private

space, but we enjoy the moment when we have the little talk before sleep, the

secrets that we dont want our parents know can talk to these girls. Whats

more, I become much independent. I learn to take care of myself and have really

grown up.

Since I went to college, I feel so excited about the new chapter of my

life. I have imagined the campus life for so many years. Now I finally come to

this stage. I have much time after class, so I need to learn to deal with it.

After two years’ struggling, I find the right way to spend my time.

The first thing for every college student is to learn major knowledge. In

China, so many students think college time is used to play instead of study, so

they skip class. This is a big mistake. College is the stage for students to

master practical skills, which decides what kind of job they will work on. So I

study very hard from Monday to Friday. I don’t want to miss the important

knowledge.

The second thing for college students is to join the after-class

activities. Joining the activities can not only learn more skills, such as dance

and sports, but also can make friends. Campus is like a small society. Students

need to learn to make connections with other students, so that they can win more

chances. I learn a lot from my new friends and know how to communicate.

My college life is wonderful, I learn both knowledge and social skills.

However mean your life is, meet it and live it; do not shun it and call it

hard names. It is not as bad as you are.

It looks poorest when you are richest. The fault-finder will find faults in

paradise. Love your life, poor as it is.

You may perhaps have some pleasant, thrilling, glorious hours, even in a

poor-house. The setting sun is reflected from the windows of the alms-house as

brightly as from the rich mans abode; the snow melts before its door as early

in the spring. I do not see but a quiet mind may live as contentedly there, and

have as cheering thoughts, as in a palace.

I have learned English for many years, as I learn more knowledge about the

English, I become more and more passionate to have a look at the world. When I

was small, I knew nothing about the world, I believe the place I lived around

was the whole world, then I came to middle school, I realized the world become

more and more bigger, but how big it was, I had no idea. As I came to high

school, I learn more about the world, There are all kinds of cultures in western

countries. I am so interested in the culture, I want to go to these places and

talk to the local people. This is my dream, I believe I can realize my dream,

since the traffic is so convenient. I must study hard and earn money, so I can

make my dream come true.

I like to travel very much. I always dream to be independent and travel by

my own. But my parents worry about me all the time. They think I will meet

problems and can’t solve. In oder to comfort them, I decide to travel with a

friend of mine and they agree. This was the first time for me to leave my home

and I had to do all the things on my own. Firstly, I book the ticket and the

hotel, and the big problem is to find the hotel. So I search the Internet and

downloaded a software to guide me, then I found my way easily. I read all kinds

of information and select the part that is useful to me. I found the funny

places and local food, what’s more, I would not lose my way. Travel makes me

stronger.

Going to high school is my first time to leave home. I have to live in

school from Monday to Friday. I like to stay away from my parents for some time,

because I can make my own choice and be free to go anywhere. My friends and I

like to spend the weekend in the countryside that near the city we live. It is

the short travel that I can not only appreciate the beautiful scenery, but also

learn to be independent. The things that nature teaches me are a lot. I can see

from the color of the cloud to predict the weather and the sound of of animals

have different meanings. All of these are hard to know from the books. I have my

own thinking from these trips, and the way to take care of myself helps me to

grow up.

Thanks to my parents, I have been to many places. I feel so lucky to

witness the scenery by my eyes. I love to travel since I was very small. I have

made up my mind that I must continue my journey on my own. As I grow up, I have

planned some trips and learned a lot.

Travel helps me to be independent. For many people, they trend to travel by

groups, which is very convenient. The companies plan everything for them, and

they just need to follow the schedules. But as for me, I only enjoytraveling

freely, so I will scan a lot of information and select the useful message. I

learn the history and culture of the countries and get to know all kinds of

applications.

The most important thing of travel is to broaden my vision. When my friends

talk about the beautiful places from the textbook, I will tell them that I have

been there and can give them my opinion. The way I talk and the knowledge I

offer to them make me stand out and I am so proud of myself.

In recent years,Waterbecomes more imporant,so how we protect the water from the pollution.

To begin with,All of the creatures made of the water,water is essential things that we live in the earth.so we cant live without water.Moreover,we can use water that we wash our faces with to flush the toilets,

In general,We should learn how to save water and make water management an important part of our life.

Saving water means saving ourselves

Water is the basic source of life. There would be no life without water.

More and more water is needed in the modern society.

Many places are short of water; many rivers and lakes are polluted. What’s worse, many people are wasting water.

In order to protect water, let’s do something to fight against all kinds of pollution and waste of water.

I remember the first day when I move to the new home, there is girl who

lives next to my house. She is very nice and willing to help me solve my

problems. Thanks to her, I get used to the new environment soon. I have made

many friends, but in my heart, this girl is my best friend. I hope our

friendship can last forever.

I have a good friend, when I was five years old, I met her, she is my

neighbor, we became friends and play together all the time. Last week, my friend

took part in the female basketball match, she is good at basketball, so I

encouraged her to join our school team. The team played so well that they came

to the final yesterday, the match was so excellent, at last, my friend’s team

won the first place, I feel so happy, I plan to buy her a present and

congratulate her. I feel so proud of her, she inspires me, too. We give each

other encourage to move on. We will be good friends forever.

There is no doubt that football is the NO.1 sport in the world, though our

football players don’t play it very well, still a lot of fans keep their

enthusiasm on this sport. They watch the matches even staying up. These fans

like to make up a group. They share the same interest and watch the match

together. It is football that brings them together.

The biggest match for football is the World Cup. As it holds every four

years, it is like the biggest event, and the whole world is crazy about it. All

the media are reporting the event and fans from all over the world gather

together, discussing it all the time.

As English is the international language, football is the international

sport. People, no matter poor or rich, can share the same topic as they come

together. People talk about their favorite players and predict the results.

Football is like the silent language, bringing people together. As the most

popular sport, it will attract more fans.

Most people in China like playing sports, because it’s a good way to keep

healthy.

In big cities, people play many kinds of sports. The old people always get

up early to play Talchi or go for a walk. The middle-aged people often dance

together in squares in the evening, which has become a tradition. While the

young like going swimming in summer and go skating in winter.

What’s more, there are some other popular sports in China, such as table

tennis, football, basketball, volleyball, badminton and so on..What is your

favorite sport? Can you tell me?

As the proverb goes, “no one knows the value of health until he loses it.”

From this, we know that health is very important to everybody. But how to keep

fit? Many people believe that sports can offer people health and pleasure. As

far as I concern, I think doing physical exercises have lots of advantages.

First of all, doing exercises in the morning will refresh my body as well

as give me a good appetite to eat my breakfast. What’s more, the air in the

morning is really fresh and clean, so I can keep my mind clear and sound in the

class. By doing physical every day I can keep my mind alert that I can finish my

tasks in time. If I do not do any physical exercise, I will feel tired and my

body becomes quite sluggish. During the night, I may find it becomes harder to

fall asleep. Second, doing exercises everyday will help me to mound a better

personality. It takes time and patient to do exercises. Sometimes I just want to

give up, but my friends encourage me to carry on, then I feel a lot of

satisfaction. Doing physical exercises makes me stronger and healthier. That’s

my personal experience.

As a student, sports are indispensable. You can pick up your favorite sport

and do it every day. Only in this way, you can have both pleasure and a healthy

body.

I like to do all kinds of sports, in the morning, I will do some jogging

and in the evening, sometime I will go to the gym with my friends. My favorite

sport is playing tennis, tennis brings my life so much happiness, I can watch

the match while talking to my friends happily. To do the sport will improve my

health and make me catch up with the time.

When I was small, one day, when I went home after school, I felt bored and

opened the TV, then I saw the tennis match. Two beautiful girls were playing

intensively, the game was so excellent, I couldn’t move my eye away from the

match. From then on, I started to fall in love with tennis, I watched many

matches and got to know more about the game.

Tennis sport is the combination of power and asthetics. The tennis players

dress the beautiful clothes and their power make the ball fly quickly. The other

tennis players will return the tennis ball with their rightly power. The game is

so wonderful, if we watch the match alive.

There is no doubt that I am a big fan of the tennis sport. I find so much

fun from it, it enriches my life.

Table tennis is one of the most popular sports in China. It’s my favorite,

too. It’s a good way of exercise, and it’s easy to play. You don’t need many

skills. I often play table tennis after class. Most of my classmates like it. So

we always have partners. But if you want to play well, it’s not so easy. You

must focus on your gesture, your hands and your steps. I want to be better, so I

practice it very often. I have my own teacher to teach me. I work hard on

it.

saving water

1 what do we use water for?

2 why water is very important in our daily life?

3 how do we save water?

参考范文

as we all know, water is essential in our daily life. we drink water every day, we use water to wash things and cook food, we also use water to make machines. people cant live without water.

我们都知道水对于日常生活的重要性。我们每天喝水，用水洗东西和烹制食物，我们还用水来制造机器。离开水，人类就无法存活。

though about 75% of the earth is covered with water, only 3% of it is fresh water. so we must save water by having a shower instead of a bath. we can save water by fixing dripping taps immediately and we can also save water by not washing under a running tap.

虽然地球75%都被水覆盖，但其中只有3%是淡水。所以我们应该用淋浴代替泡澡来节约水，同时及时修好滴水的水龙头，并且不要开着水龙头洗东西。

海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个，其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来，所以盐度增大。

当然，如果这种方式走向极端，将会余下白色的盐晶体。与蒸发相反的是降水，如降雨，由此水被加入海中，海水被稀释，从而盐度降低。

这种情形会发生在大量降雨的地区，或江河入海岸处。因此，盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说，在阳光很

强烈的热带地区，海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理，在江河稀释海水的海岸地带，海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时，溶于其中的物质被留了下来。这样，在新形成的海

水冰面的正下方的海水比在冰形成之前有更高的盐度。

当然，当冰融化的时候，会降低周围水中的盐度。

在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。这些大密度的海水下沉，可以在世界海洋的深水域发现。

if the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. nevertheless, some of these small changes are important. there are three basic processes that cause a change in oceanic salinity. one of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. in this manner the salinity is increased, since the salts stay behind. if this is carried to the etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted so that the salinity is decreased. this may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.a third process by which salinity may be altered is associated with the formation and melting of sea ice. when sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.in the weddell sea antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. this heavy water sinks and is found in the deeper portions of the oceans of the world.

水——20亿人生命的源泉；水——世间万物生存的希望；水——人类最渴望的目标。然而，这样可贵、神圣的生命之水，却因为人类的自私，人类的贪婪，在人类的摧残下，毁坏了一切。

慢慢的，慢慢的，世界上缺水的国家，缺水的省、市、自治区越来越多。目前，世界上就有335000000人没有足够的水。随着科学事业的逐渐发展，厂房高楼的逐渐增多，水短缺问题越来越严重。随着人类的破坏，原来的那个蔚蓝色的水晶球已经不再明澈，不再蔚蓝了，即将干枯。

虽然地球71%表面覆盖的是水，但是其实淡水资源只占了地球总水量的2%左右，而可被人类利用的淡水总量只占地球上总水量的十万分之三，占淡水总蓄量的0。34%。由此可见，地球上可被利用的水并没有人类想象的那么多，如果让它们继续遭到人类的摧残，早晚有一天，它会消失的。因此，我们应该保护水资源，为保护水资源尽到自己的一份力。

虽然我还是一个12岁的小学生，但我要用我手中的那支神圣的笔，呼吁大家保护水资源。

水的自述

我是水，纯净的、美丽的、清雅的、高尚的水，我从雪地来，我从山中来，慢慢地、缓缓地，穿透高山，跨过平原，汇入大海。

我是水，晶莹的雪，是我的前身，甜甜的雨，是我的兄弟，苦涩的泪，是我的姐妹。我的足迹遍布地球，我的臂膀爱抚着每个角落。

只因为有了我，生命才会如此完美；只因为有了我，世间万物才如此完善。我不但是田地丰厚的营养品，是农作物的增长剂，更是人类必有的东西。淘米洗菜需要我，洗衣灌溉需要我，人们渴时喝的是我，脏时洗的是我，急时用的是我，但是不断破坏的也是我。

我给人类带来了幸福，可人类为什么这样对我？我默默地，无私地哺育着大地。我在山的腰间潺潺流动，在草原的中间快乐奔腾，在大海的怀抱中汹涌澎湃。我是善良的、忠诚的。我把一切都奉献给人类，面对人类的冷漠无情，我会不由自主地发怒，泛滥成灾，能够主宰万物的是人物，可破坏生态环境，也是人类当今中国正面临着两大问题：一是资源问题，二是环境问题，其中资源问题中，中国人均水资源占有量是世界人均占有量的一半。环境问题中，我的污染程度更是不言而喻了，我受到侵犯，就会影响水生物和家作物的生长，增加疾病疾病的传播，危害人体的健康。因此，保护环境是刻不容缓的事实，实施可持续发展战略是是加快社会主义现代化的必然捷径。人类只有一个家园，请爱护这个唯一的摇篮。

因此，我希望得到人类的珍惜，更希望得到人类的保护。请停手吧，不要再折腾我了！

青山绿水今何在？

幕幕往事，还是易如反掌地时时浮现。

记忆中的家乡的水，很美！平淌静如画，与青山相互照应，所以青如山之绿；有的会成溪，随处可见。那便是家乡的水。

当你伸出手轻抚它时，它便从手指间滑过，柔柔的，清凉可人。在我第一次到那的时候，天天到那儿去用那水洗脸。那时正是炎夏，我便和爸爸在里面游泳。扑咚！一声跳进水里，顿时洗去了所有的疲惫，清凉遍布全身，犹如在人间天堂一般。

又一次，在五年之后，我和爸爸、奶奶再次来到了这里。一到河边，就被眼前的一切惊呆了。我竟难以相信这就是我深深难忘的家乡水。

还有湖南著名的湘江也是

听父母说，以前，湘江水特别明澈，一到炎夏就有很多人来游泳。人们亲切的称它为绿色之河。

然而现在，古老的湘江已经被吞噬了，只见河面上浮满了塑料、药瓶、白色污染发出令人恶心的臭味。享有绿色之河之称的湘江已成为了一条死河。

忽然，我明白了，今日的人们一味的追求发展，而忽视了保护环境，保护水资源的重要性。

整条河上回响起河水的叹息声：人们摧残了我的躯体！

唉！青山绿水今何在？

如果失去水

人们啊人们！

如果失去了水，你喝什么？用什么来灌溉每一寸土地，用什么来滋润每一株小草？如果没有如此美丽的水，又哪来苏轼的千古佳句水光潋滟晴方好？如果没有水，世间万物又何在？

当我们面对这样的水时，您还会歌颂它的美丽，感叹它的生机吗？面对摆在眼前的事实，难道还不足以给人们敲响水之患的警钟，敲醒人们的觉悟吗？

俗话说：失去了，才懂得珍惜！

人们，难道真的要让最后一滴水成为人类伤心欲绝、悔恨觉悟的眼泪吗？请不要失去了后才懂得它的珍贵，到那时候恐怕后悔也没用了。

请珍惜每一滴水吧！不要再对其进行糟踏了。就把这当作给水的报答吧！
