airpollution英语作文80词(汇编20篇)

This weekend, there was an art festival in our school, it had been hold for

five years and the school insisted to make it become the feature. I was so

excited, this was the first time for me to join. Early in the morning, I saw

there were so many people coming to the campus, making the campus so lively. The

students dressed so well and gave the warm welcome to the guests. I walked

around and appreciated the painting, every work was drawn by the students, I was

so impressed by these works. There were also some handworks, which were so

creative, it reflected the students’ wisdom. Though we were busy with our

subjects most of the time, some students still kept on their hobbies and made it

their talent. I should learn from them and develop some interest.

There is an old Chinese saying: Top students come from strict teachers.

Perhaps affected by this saying for a long time, we believe it right. However,

as time flies, lots of things have changed. Therefore, I am eager to discuss

what relation is the best between teachers and students.A teacher can treat a

student in two ways .One is strict, and the other is friendly. Most teachers

prefer the first way.To start with, we certainly have to admit that strictness

is very effective, especially to the naughty pupils.

As pupils we aren’t able to control ourselves well or fix our attention on

one thing for a long time. We do most things because they are interesting or we

feel like doing. We are always looking out of the window in class. Sometimes, we

get to play games and forget our homework. On this occasion, strictness is a

must. It not only forces us to do the right thing, but also helps us develop a

good learning habit, which is of great importance during our whole life .In

other words, it is the first step to success.Still, everything has two sides.

Its weak points are very obvious. You see, there’re top students in a class,

where average students make up the majority. Then teachers’ orders or

suggestions are for the majority, not for top students. However, top students

always have their own study plans and prefer special homework, so orders usually

won’t take great effect on them.

Maybe you have thought out that teachers can give orders only to the

majority and set some freedom to top students. However, it’s impossible .For a

whole class, teachers couldn’t give order to part of the class, for the majority

would question why they needn’t do such work, but we need? It would be probable

that they think teachers treat them not equally, and will not obey teachers’

orders any more. This is a difficulty for teachers.It also has another

disadvantage——the communication problem .Since teachers are strict, we never

tell teachers our personal affairs or secrets. Mostly we just tell them to our

friends, but as students too, they couldn’t help to solve our problem, such as

puppy love, communication problems or study problems .Not being solved

completely, they always disturb us, influencing our daily life and study. I’m

sure that you think that making friends with teachers can solve the problem, and

you are eager to do so as well. But if we do so, new problems will come out .You

see, an adult couldnt control himself well at times, let alone us students.

However if teachers are our friends, I doubt whether their orders will take

effect any more .You see, have we ever treated our friends’ orders as orders? We

think they’re only jokes. This is another difficulty for teachers.Additionally,

our parents have the same problem. Yes, we need to be friends, but not complete

friends. We need to keep a certain distance, making us communicate well and

willing to take your orders. I remember a story.One day, a lady had her rest

room decorated. And a skilled worker was bricking up the wall. Seeing large

cracks between the bricks, she questioned why. The worker told her after this

summer, the bricks would become bigger, and those cracks would disappear.That is

not only decoration, but also communication. The principle is the same.

Halloween

Halloween is an autumn holiday that Americans celebrate every year. It means "holy evening," and it comes every October 31, the evening before All Saints Day. However, it is not really a church holiday, it is a holiday for children mainly.

Every autumn, when the vegetables are ready to eat, children pick large orange pumpkins. Then they cut faces in the pumpkins and put a burning candle inside. It looks as if there were a person looking out of the pumpkin! These lights are called jack-o-lanterns, which means "Jack of the lantern".

The children also put on strange masks and frightening costumes every Halloween. Some children paint their faces to look like monsters. Then they carry boxes or bags from house to house. Every time they come to a new house, they say,"Trick or treat! Money or eat!" The grown-ups put treat-money or candy in their bags.

Not only children, but most grown-ups also love Halloween and Halloween parties because on this day,they can disguise themselves as personages or ghost as their imaginations will lead them. This bring them the satisfaction of being young.

万圣节前夕

万圣节前夕是美国人年年都会庆祝的秋季节日。它的意思是“神圣的夜晚”，在每年的10月31日，也就是万圣节前夜。但实际上这不是一个真正的宗教节日，而主要是孩子们的节日。

每年秋天蔬菜成熟可以食用的时候，孩子们就会挑出大个儿的橙色南瓜。然后在南瓜上刻上一张脸，把一根点燃的蜡烛放在里面。看起来就好像有人在向南瓜外面张望。这些灯就叫做“iack-o-lantems”，意思也就是“杰克的灯”。

每年万圣节前夕孩子们还戴上奇怪的面具，穿上吓人的服装。有些孩子把脸刷成怪物。然后他们拿着盒子或袋子挨家挨户串门。每来到一个新房子他们就说：“不款待就捣乱!给钱还是吃的!”大人们就会把用来招待的钱或糖放在他们的袋子里了。

不仅孩子，许多成年人也喜欢万圣节前夕和万圣节前夕晚会。因为这一天他们可以根据自己的想象把自己装扮成名流或幽灵。这会带给他们年轻的快感。

When it comes to success, different people have different opinions about

what makes it come true. Some people regard hard-working as an essential quality

to success while others believe being clever would lead to success. From my

point of view, I think perseverance and hard-working are indispensable for those

who want to make an achievement.

Firstly, perseverance let people step closely towards success. Most people

want to make a big difference to prove their value. People who set their goal

and keep moving would make their dream come true. However, there are some people

who set their goal but they stop at the difficulty would fail in the end. I

think the difference between success and failure is perseverance. If we have

perseverance, even if we are not clever, we will make a great difference, but if

we not, we are doomed to lose. As we all know, Edison is a great inventor in the

world. However, before he invented the bulb, he kept trying for tens of

thousands of times to find a suitable wire. Let us imagine, if he gave up at the

999th, then how he couldn’t become so successful. So, I strongly believe that

perseverance produces success.

Secondly, there is also a kind of people who are born with cleverness, I

think they are lucky. Nevertheless, if they don’t make a hard work on their way

to their goal, they, absolutely, will become loser. Whether we are gifted for

intelligent, we must be hard-working so as to success. I regard hard-working as

an efficient approach to be successful because I believe ‘pains and gains’. As

for those who do not make great efforts on work, failure follows. In old times,

there is a clever boy who can make excellent poem when he can talk. When his

father found the little child’s cleverness, he just let the child make poems to

show around while never let the boy learned anything. When the boy grew up,

people forgot him because he lost the ability to compose poems and became

ordinary as others. From this matter, we can see that only by hard-working can

we get knowledge and make a good future.

Anyway, I think perseverance and hard-working are both important in our way

to success for they enhance us and produce success.

It is known to all that Christmas Day is on December 25th. It is the

biggest day in the western countries. But not so many people know about the

White Christmas in China. The day before Christmas Day, if it snows, then the

world is in white color. People are happy about that, because they think it

means the happiness and luck. So that’s the meaning of White Christmas. It

always snows a lot on Christmas Eve, because it is in winter in the western

countries. All the families get together and enjoy their moment while watching

the white snow. What an enjoyable atmosphere for a family.

I am a third year master major in automation at Shanghai Jiao Tong

University, P. R. China. With tremendous interest in Industrial Engineering, I

am writing to apply for acceptance into your Ph.D. graduate program.

Education background

In 1995, I entered the Nanjing University of Science & Technology

(NUST) -- widely considered one of the China’s best engineering schools. During

the following undergraduate study, my academic records kept distinguished among

the whole department. I was granted First Class Prize every semester,In 1999, I

got the privilege to enter the graduate program waived of the admission

test.

At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5%

in the department. In the second semester, I became teacher assistant that is

given to talented and matured students only. This year, I won the Acer

Scholarship as the one and only candidate in my department, which is the

ultimate accolade for distinguished students endowed by my university.

Presently, I am preparing my graduation thesis and trying for the honor of

Excellent Graduation Thesis.

Research experience and academic activity

When a sophomore, I joined the Association of AI Enthusiast and began to

narrow down my interest for my future research. With the tool of OpenGL and

Matlab, I designed a simulation program for transportation scheduling system. It

is now widely used by different research groups in NUST. I assumed and fulfilled

a sewage analysis & dispose project for Nanjing sewage treatment plant. This

was my first practice to convert a laboratory idea to a commercial product.

In retrospect, I find myself standing on a solid basis in both theory and

experience, which has prepared me for the Ph.D. program. My future research

interests include: Network Scheduling Problem, Heuristic Algorithm research

(especially in GA and Neural network), Supply chain network research, Hybrid

system performance analysis with Petri nets and Data Mining.

China has the history of more than 5,000 years. Many foreign people are

attracted by this big old country. They come here and want to know about the

traditional culture. However, Chinese young people dont show much interest in

the old culture, instead they chase the fashion and some even abandon the

precious culture. For example, paper cutting, one of the excellent arts that is

inherited by our ancestors. Many foreign media speak highly of this great

handicraft and they are astonished by the wisdom of Chinese people. I have seen

this art when I stay in my hometown. Only few old people can do it. They just

take it for killing time. Paper cutting is like the old fashion and is forgotten

by the young generation. The media should report more positive information about

the traditional culture to inspire the young people to learn.

Because the Palace Museum is a place of five thousand years of brilliance

and ancient culture, so he has long been a tourist attraction in my heart, and

this summer vacation I have finally made a dream come true.

In Beijing I will ride my father and mother went to the tiananmen square,

across tiananmen square, the meridian gate of the world-famous greeted the hall

of supreme harmony, the hall of supreme harmony majestic, magnificent, colorful

glazed tile, such as a long arranged very neat. Curved corner with a monster,

four up the eaves of the cock appear grand hall of supreme harmony, to the hall

of supreme harmony, seventy-two large andalusite carved dragon painted chicken

shows the architecture of the feudal monarchy. The golden roof reflects the

majesty and status of the ancient Chinese emperors. The great hall looked solemn

and solemn, but the beauty of the appearance was so monotonous and heavy that I

was in vain. I dont know why I feel as if a group of puppets are standing

respectfully on either side of the house. Incense sticks up in the incense

burner, and the emperor sits high in the temple. The Palace Museum, a symbol of

the ancient kingship, has been invaded by a brick and a brick. It is far from

the palace of Buckingham Palace.

In the afternoon, we in addition to the front door, look back at taihe

light standing in tiananmen square, this magnificent buildings, so the layout of

the orderly, so solemn, not amazing, hope this trip to the Forbidden City will

become my eternal memory.

When talk about tennis, most people’s reaction is money, because for

Chinese people, it needs a lot of money to play tennis, so only the rich people

can have the chance to be a tennis player. But now, as our country’s economy

develops fast and the globalization of tennis, playing tennis is not an

untouchable dream, everyone can have access to tennis.

Tennis match is very popular in the western country, every year, there are

a lot of tennis tour matches, ten years ago, not so many Chinese people know

about the tennis matches, but as the game become more and more popular, people

start to fall in love with tennis match. We can see that Chinese tennis players

start to show on the world stage, they have won so much honor. Li Na is the

first Asian player to win the grand slam, her great success inspires so many

Chinese players to work on the tennis career.

Tennis is the world’s third game, football and basketball rank first and

second. The globalization of the tennis will make more and more people fall in

love with tennis.

Teachers Day

I still remember the year when I failed the collage entrance exmination.Iwas feeling lost,and no idea about what my life is going to be.My teachet came to me,and she said she understand how I felt inside now.She also told me its very common that students who are like me will go though a hard time. She told me that failure was a part of life, which was not the end but a new beginning. And she encouraged me to go back to the school to start a new. I was convinced in the end and decided to give another try.

Now Ive graduated from collage and got a very good job.I know all my success owns to my kind teacher. Ill work harder and never give up again.

People always attach the importance to the promise, they hate people who

break their promise. I remember once a time, my friend asked me to go to see the

movie with her, I said yes without hesitation. But on that day, I forgot about

the date, I just woke up late and then played computer games in my bedroom. My

friends called me, she asked why did I disappear, I said I was sleeping at home,

she became very angry, until then did I think about our date. I felt so sorry, I

break my promise for the first time, I realize I did the very bad thing. Even

though I apologized for many times, my friend was still angry with me. I learn

the lesson, promise is very important, we must keep it, other people will see

through our personality to decide what kind of person we are.

Nowadays, an increasing number of people are willing to serve as volunteers

especially the university students in that they consider that volunteering is

not only a great contribution to our society and those who are in need, but also

improves themselves in many aspects.

For one thing, there is no doubt that volunteering makes contribution to

our society and people in need. The volunteers provide their assistance without

requiring any financial rewards. Their contributions have a great impact on

harmony society contribution.

For another, serving as a volunteer is also beneficial to the volunteers

themselves. They can improve their communication skills when providing help for

others. One of the examples is that the university students who serve in Canton

Fair will get a great chance to practical their English and get in touch with

different kinds of people as well as broad their horizon. In addition, by

serving as different kinds of volunteers, they are easier to understand

themselves and know in which fields they are interested.

In a word, volunteering has brought many benefits to our society, those who

are in need as well as the volunteers themselves. Therefore, let us enjoy the

time when serving as a volunteer.

Darfur once said that, “The future of illiteracy is no longer illiterate

people, but did not learn how to learn.” In the future world, everyone has to

face the contemporary issue that learn to learn, which is the key to the

lifelong learning as well as the permit to the era of knowledge economy.

Firstly, having an aim is the premise of learn to learn. The goal is the

direction of learning, only when you set up a goal can you have motivation.

Secondly, autonomic learning is the foundation of learning. Study is a lifelong

task. When we stay in school, we have teachers teaching. But after we graduate,

we have to learning independently, and atonomic learning seems particularly

important. Thirdly, scientific learning methods are the keys to learning, which

conductive to cultivate and improve a variety of learning abilities so as to

improve learning efficiency. Finally, make plans for your learning.

There are many funny places in ourSchool. For example, the football

playground, the classroom, the experiment room. But my favorite place is

school’s reading-room. Our school’s reading-room is very big and bright. After

class, you can go inside and pick out one of your favorite book to read. There

are so many books that you don’t know which one you should read first.

I love reading. And J.K Rowling is my favorite writer. I have read the

Harry Potter series so many times but I never get bored. In my opinion, reading

books not only broaden my horizon, but also help me to be a better man. I can

learn different things from these books. When I feel blue, I will go to the

school’s reading-room. In that place, I can forget my trouble when I read my

favorite novels.

May 12th, 2008. That’s the most mournful day for our Chinese that will

never be forgotten, because a horrible earthquake happened in Wenchuan, which

caused tens of thousands of children’s death.

On hearing the news, I felt so sorrowful. “Why was the god so cruel to

them?” I asked. They were still at the entrance of the life. They seemed like

little eagles that were willing to open their wings and hover in the sky. Maybe

they would have their brilliant future. What a great loss to our nation! I had

my deepest sympathy on the people in the disastrous area. So I donated some

money and clothes to them. And I also prayed for the dead people sincerely. I

eagerly hope that there would be no earthquakes in the future, so that we could

live a more peaceful life.

Once a child asked such a question: What can I benefit from being "a good

child"? Among the many answers he received one ran like this: "A good child" is

the most precious gift God gives to you. And the same can be said for being

honest. It pays to be honest.

Yes, its true that dishonesty exists almost everywhere in the society.

Consumers often found themselves being blackmailed by those merchants selling

shoddy products; and there are students

Cheating in order to pass the exams or get high marks; moreover, we are not

short of examples that many rich professionals evade the taxes by sacrificing

the interests of government.

But havent we seen their results? "A fall into the pit, a gain in

customers wit", which would surely drive those dishonest merchants out of

business. Regret of wasting time yet being

Empty-handed would accompany those dishonest students all their life. On

the contrary, we could have all they lost, especially a good reputation and a

clear conscience, which are the best qualities of human beings. Thats why we

say "It Pays to Be Honest".

Science and technology have been bringing human beings tremendous benefits.

Thanks to science and technology, we now live comfortably and conveniently in

houses furnished with air conditioners, refrigerators, washing machines and

televisions etc. Thanks to science and technology, we can eat fresh vegetables

at the year round. Thanks to science and technology, we can travel long

distances in the fraction of a second on planes, trains and cars. Thanks to

science and technology, we wear clothes with synthetic materials which can not

easily be worn out.

However, science and technology have atso brought us a lot of disasters.

First, because of the many breakthroughs in the field of medicine, people are

now living much longer than they used to. As a result, the population of the

world is increasing, causing lots of problems. Second, because of the

development of industry, lots of the wastes from factories pour into the air and

rivers, causing pollution of all kinds. Third, some terrorists are using science

and technology against mankind. They use biological, chemical and unclear

weapons to threaten world peace...

So its urgent that we find ways to solve these problems. But we should not

stop the development of science and technology because of these disasters they

bring, just as we should not give up eating for fear of choking. In addition, we

should make some rules to regulate our actions. As long as we use science and

technology in a proper way, they may bring us even more benefits.
