It is said that Chengdu is a city which if you come you cant leave.It has

a long history.there stands Du Fus thatched cottage ,The Temple of Zhugeliang

and some other place of historical interest.They are all so famous that many

foreign tourists like to come here.Chengdu also has a comfortable weather for

people who live in there.Even though in the winter it is still warmer than any

other cities in China.Besides,as Chengdu people are fond of eating,they have

created many delicious food such as hot pan,Three Big guns,and some others.

It is reported that thick fog and haze surround many parts of China. People

have to wear masks when they go out.As air pollution is getting increasingly

worse,it has become the main concern of people.

Air pollution can have serious consequences for human’s health and also

severely affects natural ecosystems. Millions of people die of illnesses related

to air pollution every year.Due to particles from exhaust emissions,green house

effects result in warmer weather,acid rains corrode the earth,and frequent haze

causes traffic problems.

Confronted with such situation,positive measures should be adopted. The

government should keep its regulatory role for properly supervision. Related

rules should be made out for reducing emissions of new vehicles and limiting

high-emission vehicles.Factories should meet standards for curbing emissions of

pollutants in surrounding cities.Meanwhile, provinces and municipalities in each

target region should set up a mechanism for the joint prevention and control of

air pollution.

Many years ago, I saw a science fiction film, which described a future

world. The way people lived was very different. They could drive cars in the

sky. Everything in the future world was so convenient. Since then, I was always

curious about how the future world would become. The fling cars seemed so

ridiculous for now, but thinking about more than 100 years ago, people never

thought about flying in the sky, but now we could take planes and traveled

around the world. Everything was possible. Whats more, the development of

technology is so fast that the world changes so much every ten years. Nowadays,

people can pay the bill online. No matter where they go, a cell phone can solve

most problems. I believe that future transportation will be much efficient and

will surprise us all.

宇称守恒定律是物理学界公认的重要原理之一，杨振宁在一次实验中发现得出的结论与宇称守恒定律冲突，便推测该定律可能是错误的。

为了验证“宇称”是否真的守恒，杨振宁和李政道合作，进行大量计算后，发现过去所有相关实验竟然没有任何宇称绝对守恒的根据。为进一步验证，他们倡议学生组建科研小组去做实验。起初没有学生愿意做，因为该定律是公认的，此前从来没有人怀疑过，而且这项实验做起来非常麻烦。不过最终有个女生愿意做，她觉得宇称守恒作为一种基本现象，既然还没有得到实验的有力证明，就应该去验证它。于是她与其他几名科学家合作，在华盛顿做了长达半年的艰苦实验。

1957年1月15日，美国哥伦比亚大学举行发布会，公布了由这个女生组建的科研小组的实验结论——宇称是不守恒的。这推翻了物理学上屹立30年之久的宇称守恒定律，震惊了物理学界。1957年l0月，杨振宁与李政道因此获得诺贝尔物理学奖，参与实验的那个女生也一举成名。她就是美籍华裔物理学家、有“东方居里夫人”之称的吴健雄女士。

1、麻烦可能就是机会。对于实验，多数人的态度是避而远之，而吴健雄却不嫌麻烦，最终为自己赢得成功的机会。为什么机会来临时，我们常常把握不住？因为机会总是乔装成麻烦的样子。麻烦来了，人们的第一反应就是避而远之，这样就错过了机会。

2、大胆质疑，挑战权威。一次实验的结论，让杨振宁作出宇称守恒定律可能是错误的推测，这体现了他不畏权威的精神。吴健雄愿意做麻烦的实验去验证，也是基于不迷信权威的精神。挑战权威是一种坚持真理的.精神，是一种实事求是的态度，更是一种敢于质疑的勇气。

3、实践是检验真理的唯一标准。为验证杨振宁和李政道的观点，吴健雄组建科研小组，以实验检验真理。可见，忠于事实，不盲从，不跟风，以坚定的勇气为船，以科学的态度为帆，才能抵达真理的彼岸！

4、成就自我要耐得住寂寞。他人避而远之的“麻烦”实验，吴健雄坚持了半年之久，经过无数次计算，其间的枯燥、艰苦可想而知。寂寞是黎明前的黑暗，没有寂寞地积累和酝酿，哪有众人瞩目时的光芒四射？

◇打开一切科学的钥匙都毫无异议地是问号。 ——作家巴尔扎克

◇耐得寂寞，才能不寂寞；耐不得寂寞，偏偏寂寞。 ——作家姚雪垠名声的作文素材。

◇因为我对权威的轻蔑，所以命运惩罚我，使我自己竟也成了权威。 ——物理学家爱因斯坦

Aducation is not an end, but a means to an end. In other words, we do not

educate children only for educating them. Our purpose is to fit them for

life.

In some modern countries it has been fashionable to think that free

education for all can solve all the problems of society and build a perfect

nation. But we can already see that free education for all is not enough.We find

in such countries a far larger number of people with university degrees refusing

to do what they think is "low"work, and. in fact, working with ones hands is

thought to be dirty and shameful in such countries.

But we have only to think a moment to understand that the work of a

completely uneducated farmer is far more important than that of a professor~ we

can live without education,but we die if we have no food. If no one cleaned our

streets and took the rubbish away from our houses, we should get terrible

diseases in our towns.

In fact, when we say that all of us must be educated to fit us for life, it

means that we must be educated in such a way that, firstly, each of us can do

whatever work is suited to his brains and ability and, secondly, that we can

realize that all jobs are necessary to society, and that it is very bad to be

ashamed of ones work. Only such a type of education can be considered valuable

to society.

Things in life than the books. It can let us know the heaven and earth,

know life. It makes our temperament, not pleased by external gains, not to

sorrow. Books are our spiritual lair, the source of life. Achievements of

ancient and modern, Chinese and foreign, to has close relationship with books,

and is good at absorbing nutrition from the book. Get into the habit of hobby is

reading books from the reading, to experience the fun of reading, learning and

mastering some reading method, this is not the first great thing in life? Now, I

will share with you to read all kinds of fun!

A great pleasure in reading than when you when you are racking their brains

for a problem, mystery, or on a particular question seems to smell, open the

book, you will find that has been done to the full, in SAO itch you. The

"steady" feeling you so comfortable, so comfortable.

Reading for fun, different people have different for engaged in manual

Labour, a leisure reading; For people engaged in mental Labour, the book can be

a panacea, boredom, reading can be permitted; When sorrow, reading can lotus;

Reading can be smoothly when excited...

Reading gives a person is calm, quiet, comfortable happy, is fame, money

can not be replaced, the spirit of the book, like the human nutrition agent,

without it, life will be defect. Let us not leave a regret, picked up the book!

Sure you can understand the true meaning of life from the book!

When memory began for me, my grandfather was past sixty-a great tall man

with thick hair becoming gray. He had black eyes and a straight nose which ended

in a slightly flattened tip. Once he explained seriously to me that he got that

flattened tip as a small child when he fell down and stepped on his nose.

The little marks of laughter at the corners of his eyes were the prodnct of

a kindly and humorous nature. The years of work which had bent his shoulders had

never dulled his humour nor his love of a joke.

Everywhere he went, "Gramp" made friends easily. At the end of half an hour

you felt you had known him all your life. I soon learned that he hated to give

orders , but that when he had to, he tried to make his orders sound like

suggestions.

One July morning, as he was leaving to go to the cornfield, he said :

"Edwin, you can pick up the potatoes in the field today if you want to do that.

" Then he drove away with his horses.

The day passed, and I did not have any desire to pick up potatoes. Evening

came and the potatoes were still in the field. Gramp, dusty and tired, led the

horses to get their drink.

"How many bags of potatoes were there?" Gramp inquired. "I dont know.

"

"How many potatoes did you pick up?"

"I didnt pick any. " "Not any! Why not?"

"You said I could pick, them up if I wanted to. You didnt say I had to.

"

In the next few minutes I learned a lesson I would not forget: when Gramp

said I could if I wanted to, he meant that I should want to.

Gram hated cruelty and injustice. The injustices of history, even those of

a thousand years before, angered her as much as the injustices of her own

day.

She also had a deep love of beauty. When she was almost seventy-five, and

had gone to live with one of her daughters, she spent a delightful morning

washing dishes because, as she said, the beautiful patterns on the dishes gave

her pleasure. The bird, the flowers, the clouds-all that was beautiful around

her- pleased her. She was like the father of the French painter, Millet, who

used to gather grass and show it to his son , saying , "See how beautif ul this

is ! "

In a pioneer society it is the harder qualities of mind and character that

are of value. The softer virtues are considered unnecessary. Men and women

struggling daily to earn a living are unable, even for a moment, to forget the

business of preserving their lives. Only unusual people, like my grandparents,

manage to keep the softer qualities in a world of daily struggle.

Such were the two people with whom I spent the months from June to

September in the wonderful days of summer and youth.

My school is very big and beautiful.There is a big playground and a big

garden are behind our teaching buildings. the garden is very beautiful.There are

about 2000 students and more than 200 teachers in my school.my teachers are very

kind and friendly.they are very kind to us,they often help us with our study.I

have many good friend.we often play togeter ,I have a great time in my school.we

are happy every day.I like my school very much.

I imagine a lot about lives in the future. I think two words can summarize

my imagination. The first word is fast. In the future, we will have more quickly

transportation means. Now matter how far we go, it takes only a short time. With

the development of science and technology, we can travel to the moon, Mars or

somewhere outer space. People may can live in other planets. The second word is

convenient. Because of the fast development of our society, many work can be

done by computers or even robots. Lots of things are fully automated. Humans

just need to give some simple instructions to complete complecated tasks.

When I see the cartoon, I like to watch the cat machine very much, he has a

Timemachine, he always helps his friend to fine something with time machine.

The cartoon makes me think of what would I do if I have a time machine. If I

have a time machine, the first thing I want to do is go back to the time when I

play with my friend, he now moves to another place, I never say goodbye to him,

I want to make it up and say goodbye to him. The second thing is I want to go

back to the time when I shout at my mother, I regret about this all the time, I

wish I had a chance to say sorry at that time. Now I have to face the truth that

I will never have time machine, I should cherish the time and thing I own now,

be nice to my mother.

Teacher is a great job in most students’ eyes. When they are asked what

they want to be in the future, most will say they want to be a teacher and make

a contribution to the society. Indeed, we have access to the teachers all the

time and they have great influence on us. So being a teacher is a ideal job for

most students, but for me, I want to be a librarian. I like reading books so

much and once I have time, I will be immersed in these novels. Books broaden my

vision, though I can’t travel to the places, I can still know about these famous

sites from these books. Being a librarian can make me have a lot of time to

read.

There is an old saying goes that failure is the mother of success. Everyone

confronts with failures even those famous and successful figures. Some people

say that failure lashes them to work harder. Some think that failures are so

depressing and we should not to make any failures. For me, I cherish failures

very much for we can realize our shortcomings from them.

First of all, we can learn from failure and get more experience. It is

indeed so disappointed when we confront with failure. However, we can always get

some experience from failures and makes us understand our weak point. If we can

learn from failure, then we will avoid such problem in the coming days.

Secondly, the more failures, the more successful we will be. As the old

saying goes that failure is the mother of success. The more failure we make, the

more successful we will be. If we make many mistakes, then we will learn a lot

from them and will do better when we meet the same kind of problems. This means

we will obtain great success if we meet more failures.

All in all, failure is a bad thing for people, but it is a good chance for

us to learn more from it and become successful in the future.

Dear Manager,

Now I am writing to tell you that I bought a TV set from your shop several

days ago. But when I brought it home and turned it on, I found it didn’t work

properly. So I took it back to the shop and told the assistant what had

happened. To my surprise, your assistant didn’t help me to solve the problem. On

the contrary, he shouted at me rudely and refused to examine it.

I know that your shop enjoys a high reputation of good service, so I bought

the TV set in your shop. But today, I am sorry to find that such service should

have happened in your shop and your assistant didn’t seriously think of the

interests of customers.

I hope you will look into the matter and give me a reasonable explanation.

I am waiting to know how you will deal with it. Thank you for your consideration

and I am expecting an early reply.

Sincerely yours,

Last Qingming Festival,i return home to worship my grandfather.Qingming

Festival is a folk Festival.In the past,the Qingming Festival was called "Arbor

Day". But Today, Chinese visit their family graves to tend to any underbrush

that has grown. Weeds are pulled, and dirt swept away, and the family will set

out offerings of food and spirit money. Unlike the sacrifices at a familys home

altar, the offerings at the tomb usually consist of dry, bland food. One theory

is that since any number of ghosts rome around a grave area, the less appealing

food will be consumed by the ancestors, and not be plundered by strangers.

With the passing of time, this celebration of life became a day to the

honor past ancestors. Following folk religion, the Chinese believed that the

spirits of deceased ancestors looked after the family. Sacrifices of food and

spirit money could keep them happy, and the family would prosper through good

harvests and more children.

With the rapid development of our society, more and more people are fond of

online shopping for its convenience. Online shopping has been a heated fashion.

But different people have different views on this point. After all, every coin

has two sides.

Online shopping has advantages as well as disadvantages. Firstly, nowadays,

the Internet has become a must. As convenient as it is, people depend on online

shopping as it caters for those who are busy with work or other things. And it

can help us save much money, which is cheaper than what we buy in the physical

store. What’s more, it contributes the Internet to the further development.

However, it is also a risk of online shopping as we pay the bill online by

our credit cards, we may be cheated by the dishonest shoppers. Sometimes the

quality of what we buy online is much worse than we could imagine.

In my opinion, when we are shopping online, we should keep wise to prevent

us from treating. And we’ll find that online shopping has advantages over

disadvantages.

Since I go to middle school, I have to learn many subjects. Though I am not

the best student in class, but I won’t give up. I always tell myself to work

hard, because if I want to compete with other students, I need to make great

effort. People are easy to deny themselves when they face difficulty. If they

fail one time, then they will doubt the effort they have made. Actually, we are

not studying in vain. What we learn will be a great help to improve ourselves.

The thing we learn decides what kinds of person we are. So don’t deny yourself,

as you will see the value you have stored before in the future.

星期天，我在培训班里玩了一个“挑战魔箱”的小游戏。

老师先给我们介绍了游戏规则：被选上的同学要依次摸一摸魔箱里的“宝物”，并猜出它是什么。听完规则后，大家都跃跃欲试，许多同学都想上去一展身手。我也想上去，可是心里想：如果是怪兽怎么办啊。我高高举起的手又放下了。

可能是老师猜透了我的小心思，还是点到了我。我有些恐慌，但更多的是好奇，一直想着魔箱里会是什么。我的身体不由自主地抖了起来，不知道是紧张的抖还是激动的抖。我的脸上虽然挂着笑容，但心里却非常地紧张，就像热锅上的蚂蚁——团团转。

上台时，我不禁打了个哆嗦，选择站在了角落里，鼻尖上还冒出了细细的汗珠。轮到我时，我才壮着胆子走了过去。老师把我的眼睛蒙上了，我慢慢地把手伸到了魔箱里，摸到了一个毛茸茸的东西，心里一惊，马上把手缩了回来，我以为是一个见什么就吃什么的怪兽。这时，我听到了同学们的掌声，他们还大声地喊到：“勇敢点，成懿哲!你可以的!”隔了一会儿，我再次把手小心地伸了进去，我心里默默祈祷：怪兽不要吃我!怪兽不要吃我!也许是受到了同学们的鼓励，我的心情也慢慢地放松了下来，我仔细的、认真的触摸着这个毛茸茸的东西，发现它原来是死的、不会动。当我正在用心琢磨的时候，老师打断了我，说：“时间到!”我便把手收了回来，取下蒙眼睛的面，我苍白的脸才渐渐恢复了血色。

回到了座位上，同学们都问我摸到了什么，我诡笑道：“只可意会，不可言传。”同学们一脸的无奈。不过，我还是要感谢你们，是你们的掌声给予了我鼓励，也让这次游戏全我留下了深刻的印象。

On October 1, I did not go out as usual.

Since it was National Day, 61th anniversary of my homeland, like many people, my parents and I just sat in the couch and watch TV.

We didn’t want to miss the program, parade. We were all excited when we saw such beautiful and magnificent scene.

There were so many people gathered together to celebrate the 61th anniversary.

From their smile, I can feel their happy, their proud and confidence.

I feel proud there are many advanced weapons to secure our country.

We, Chinese, are never aggressive. We love peace.

We know how to secure the peace because Chinese is the victim of war.

When I saw 61 flower buses passed through Tian An Men, I am so excited.

I believe our country will have a prosperous future.

China is the biggest family with 56 ethnic groups. Among them, the Han

Chinese is the largest and the most highly developed group. The Han Chinese can

be found in many parts of China. They mainly live in the north plain region, the

middle and the lower reaches of Yangze River and Pearl River Deltas. The other

55 groups are the minority ethnic groups. They are distributed in the

mountainous areas of southwest and northwest of China.

Being too far away from big cities, the minority ethnic groups are poor in

economy and there people are not well-educated. They have very few

understandings of science and technology. So they must develop their

economy.

To help the people of the minority ethnic groups live better, the

government should take some effective measures. For one thing, more and more

knowledgeable undergraduates should be encouraged to those poor areas to help

the people there to get rid of their poverty. For another, the advanced science

and technology must be introduced into the minority ethnic groups to improve

their living conditions. More importantly, people of the minority ethnic groups

should be given equal opportunities to study and work. Only so will China be

more prosperous in the future.
