绿色环境是健康的一种象征。绿色能带给我们生机、带给我们活力。我们的学校——镜湖小学，是一所绿色的学校。

在我们的校园里，到处都可以看见绿色：操场的隔离带，松树高大挺拔，一年四季都是披着绿色的长衣，铁树刺如针一般锋利;教学楼前后、大门前，也都有花坛和花园装饰，就连跑道旁都长满了许多碧绿的小草，和穿着红色衣服的枫树。

我们的学校有了绿色，好处还真是不少呀!同学们来到学校，都能呼吸清新的空气，使人心旷神怡。如果在考试前去绿荫边休息一会儿，让我们头脑清醒，说不定分数也会提高不少呢!

我们的校园里，花坛随处可见，其中最漂亮的就要数食堂旁的那个花园了。那里杨柳如丝，漂亮之至。在春秋季节，百花盛开，花香弥漫了整个校园。花园中间有个小池子，有许多沙子，风儿一吹，它们就飘了起来。

里面这美丽的景色可不是天然的，是我们学校的艺术工人精心设计的。在他们的手下，一簇簇绿色像画一样装饰着校园。我们每天负责把落叶，杂物清扫干净，让校园永远保持美丽，让这幅画永远保留下来。

怎么样，我们的绿色校园是不是很美，您若还不信，就快来参观参观吧。

Health is most important for any of us. ]n order to stay healthy, we need some common knowledge.

First]y, pay attention to the diet. We should eat lots of fruit and vegetables, because they are rich in fiber and Iow in fat. As a proverb says, An apple a day keeps the doctor away. So fruit is good for health. Dont have a lot of food that contains too much fat, such as butter. Meanwhile, sweets should be eaten in proper quantity, because too much sugar does harm to us. Dont drink too much coffee,either

Secondly, exercise is necessary. Regular exercise can help us keep from getting fat. People who do running every day usually have stronger hearts than who dont.

Finally, form good living habits. We should sleep for about 8 hours at night,and never work too hard. Over work and little sleep will lead to illness. Whats more, stay away from cigarettes.

These are the things we should pay attention to so as to stay healthy.

Spring comes at last. Everything begins to grow. The trees turn green, and the flowers come out. On the playground, in the fields, on each side of the road, the young grass grows everywhere.

Spring also arrives in our school. Come and see, behind our teaching building, there are some small pear trees covered with white flowers; on both sides of it, there are some other flowers smiling at you, Some are yellow, some are red. In our school garden, more flowers are there. All kinds of flowers of many colours can be seen.

Look, there are some Kites flying in the sky. The spring wind is blowing. The sun is shining brightly. Some boys are playing games in the sun, Listen, a group of girls are singing Where’s spring? It sounds like the singing of lark birds. All these make me think that spring is here, spring is there, and spring is just in our school. Fhe boys and the girls are all like flowers in spring.

Long long ago, many families had three or four children. They couldnt look after everyone well, so the children must do everything by themselves. They were too poor to go to school. Some of them liked learning, but they had to go to find jobs to make money. Since they were children, they could do lots of difficult things like their parents. Sometimes they even did better than them!

But now, many families have only one child and they regard their child as a pearl. They did everything for the children. Every day, when the child gets up, their parents help him to make the room clean. They also get breakfast ready for their child. When the child is free, they can sleep or do other things, but they neednt do any housework. So many children cant cook; wash their clothes, some dont even know how to clean the floor. That’s too bad.

In the future, many families will have computers. We can work on the computer instead of going out to do everything. The children also can learn on the computers, so they dont need to move! After a long time, well become fatter and fatter. We wont be able to do anything by ourselves!

So, which way is good for us? We must think more.

很久以前，许多家庭有三或四个孩子。他们不能照顾好每一个人，所以孩子们必须自己做所有的事情。他们太穷上不起学。尽管有些人喜欢学习，但是他们不得不去找工作赚钱。当他们还是个孩子的时候就像他们的父母一样能做很多困难的事情。有时，他们甚至比他们父母做得更好!

但是现在，很多家庭只有一个孩子，他们把孩子视为掌上明珠。他们所做的一切都是为了孩子。每天，当孩子起床了，他们的父母帮他把房间打扫干净。还为孩子准备早餐。当孩子空闲的时候可以睡觉或做其他的事情，但不必做任何家务。很多的孩子不会做饭,不会洗自己的衣服，有些甚至不知道如何扫地。这样太可惜了。

在将来，许多家庭拥有电脑。我们可以在电脑上工作，而不是去做每一件事。孩子们也可以在电脑上学习，所以他们不需要走动!长时间以后，我们会变得越来越胖。我们做不了任何事情!

所以，什么样的方式对我们是好的?我们必须想得更多的。

I am in Xianchi Railway MiddleSchool. There are about 40 teachers and 900

students in my school. Its very large with two small gardens. Some small trees

and flowers are planted. We enjoy beautiful flowers in spring, summer and

autumn. They are the places the students like most. There are two modern

teaching buildings and a teaching building in my school. Our classrooms are

large and bright. We feel so happy to study in such comfortable classrooms.

Besides, the teachers in our school are so excellent that they are popular in

our students. Students build a good relationship with teachers. I am sure you

will like my school.

Beijing has a history of over 3,000 years with a population of nearly 13

million and a lot of places of interest around it. In recent years, the city of

Beijing has been advancing very quickly. You can see more museums, parks an

shopping centers here and there. More and more highways and overhead walkways

have been built up. Whats more, a lot more buses which burn cleaner fuel, such

as CNG or LPG, are put into use, to prevent air from being polluted. Water in

the rivers is clean again. Wherever you go, you can see green trees, grass and

beautiful flowers. All these make life in Beijing more convenient, pleasant and

colorful. Beijing is still advancing to the bright future.

That was a morning in the early of June. I took a bus to my school in the suburb which was surrounded by rice paddies and ponds. The sky was gray with the gloomy clouds congregating gradually along the far eastern horizon. "There must be a heavy rain soon." I spoke to myself.

When I hurried into the classroom, the sky, gray before, was shrouded now by black clouds, darken to twilight, I felt quite stuffy, while it was quite calm, without wind. I saw the leaves of trees and grass static, which seem to await something tohappen. Several minutes later, I saw the lightening split the clouds and heard the thunders following. Suddenly, the curtain of rain fell and the wind blew. soon the grass flattened under the wind and the rain. With the rain forming like a fog, the sky became bright. I took several deep breathes. I felt comfortable.

The heavy rain lasted three hours and stopped when the class was over. The air was so fresh and the sky was so clear. I felt like a new man myself.

Far and away the most important holiday in China is Spring Festival, also known as the Chinese New Year. To the Chinese people it is as important as Christmas to people in the West. the dates for this annual celebration are determined by the lunar calendar rather than the GREgorian calendar, so the timing of the holiday varies from late January to early February.

To the ordinary Chinese, the festival actually begins on the eve of the lunar New Years Day and ends on the fifth day of the first month of the lunar calendar. But the 15th of the first month, which normally is called the Lantern Festival, means the official end of the Spring Festival in many parts of the country.

Three days ago we decided to visit the Great Wall.

Today we met at the bus stop early in the morning. When we were on the bus, we saw a lot of new buildings and new shops.Beijing was taller than before, I thought.

It took us about two hours to get to the Great Wall. When the Great Wall appeared in front of us, we couldn , t help thinking how wonderful it is! I wondered how the people in the past built it without modem machines. It is said you can see it from the space.I was proud of it.

After coming home I made up my mind to study harder than before. When I grow up, I will work hard to make our country more beautiful and stronger.

In recent years, it has been reported that a large number of people cut

trees down without a plan and triggered many problems. From this matter, we

should realize the importance of trees and take measures to prevent this kind of

inappropriate action.

The importance of trees is mainly featured in following aspects. First, it

is well-known that trees provide us with woods and other products. In addition,

trees are very helpful in preventing water loss and soil erosion and keeping the

nutrition of soil. Finally, trees have a great contribution in purifying air and

make our environment be fresher.

Therefore, in order to make our earth become better, we need to take some

actions to prevent this action of cutting trees without a plan. For one thing,

our government needs to take some mandatory measures to prevent illegal felling.

Besides, our government should keep advocating people planting trees as many as

possible. For another, we need to enhance our awareness of trees protection and

environment protection, and participate in all kinds of activities of planting

trees and protecting trees.

This summer, I had some special days. I joined dongzhou international educational exchange summer camp.

First, I will tell you about our foreign teachers, they are shrina and rebecca. They are friendly and beautiful. They are students at oxford university.

We talked about many things: famous people, subjects in england, different jobs, our deal days, western star signs, what can we say in a restaurant and so on.

We know lots of things, like what the difference is between “chef” and “cook”, all the parts of the body…

We tried to write a letter to principal zhang. We made a play and we drew our own comics and tried to sell it. We gave some other students english lessons, we taught them about chinese dragon, chinese martial arts and the olympics.

Every afternoon, we played exciting games: chinese whispers, tongue twisters, wheelbarrow, egg and spoon, three legs…

On the last day, we had a good time. We made black tea. We put tea bags, some milk and lots of water in to a big bowl, and then we stirred the tea until it became red and dark. Oh, it tasted good! later, we used eggs, flour and milk to make many pancakes. To cook them is very interesting. When we finished it, the pancakes looked round and nice. We put some jam on it. how delicious! I won’t ever forget it.

The summer camp is a really good chance for me. I know the local things in england. I learned a lot and like english more. I also know better ways to learn english well.

I hope one day i can see you in england.

Money and the Meaning of Life Recently,a professor of philosophy in the

United States has written a book called Money and the Meanlng of Life. He has

discovered that how we deal with money in our day-to-day life has more meaning

than we usually think. One of the exercises he asked his students to do is to

keep a record of every penny they spend for a week. From the way they spend

their money, they can see what they really value in life. He says our relation

with others often becomes clearly defined when money enters the picture. You

might have a wonderful friendship with somebody and you think that you are very

good friends. But you will know him only when you ask him to lend you some

money. If he does, it brings something to the relationship that seems stronger

than ever before. Or it can suddenly weaken the relationship if he doesnt. This

person may say that he has a certain feeling, but if it is not carried out in

the money world, there is something lereal about it.

People just have an idea of ma-ki-ng more and more money, but what is it

for? How much do I need for any given purposes in my life7 In his book, the

professor uncovered an important need in modern society: to bring back the idea

that money is an instrument rather than the end. IMoney plays an important role

in the material world, but expecting money to give happinemay be missing the

meaning of life.

On June 5, 1972, the United Nations was held in Stockholm the United Nations conference on the human environment, the meeting adopted the declaration of the human environment, and puts forward 5 June every year would be a "world environment day". In October the same year, the 27th United Nations general assembly adopted a resolution to accept the proposal.

1972年6月5日联合国在瑞典首都斯德哥尔摩召开了联合国人类环境会议，会议通过了《人类环境宣言》，并提出将每年的6月5日定为“世界环境日”。同年10月，第27届联合国大会通过决议接受了该建议。世界环境日，是联合国促进全球环境意识、提高政府对环境问题的注意并采取行动的主要媒介之一。

It is obvious to everybody that the only way to achieve ones goal is to work hard. Just as the old saying goes no mill, no meal. Have you ever seen a man who succeeds just by idling about? Of course, the answer is No. So we know if you want to gain something, you will have pains.

The farmers harvest by a year of arduous work; the scientists gain achievements by years of devoted researches; students get good marks by working hard; even the little ants have their food by working hard day and night. 1 know there are always some people who wait for the opportunities falling on them. They may attribute their failures to lack of good chances. Therefore, there are so many people gaining nothing at last. Clever men know that the more effort they make, the bigger chance they will have to be successful.

So, when others achieve their aspirations and you still gain nothing, dont complain about the unfair fate and dont give up, either. Remember: no pains, no gains.

According to my collection to a report said:"the environment problem is due to human is not reasonable to develop and make use of the natural source caused by environmental problems.Red main air pollution,water pollution,noise pollution,food contamination,not suitable development and utilization of natural resources it five categories." As one of the fact that we iron,they are like a demon ruthless swallowed with human life.It threatens the ecological balance,the harm to human health,and restricts the sustainable development of economy and society,it lets the human was in trouble.For this I make declared:"as long as we have not forgotten--human moment of the environmental protection consciousness,have the consciousness of the environment according to law,the global village will be beautiful paradise".The future of the sky of dark blue must be,water is clear,the green flowers,can enjoy the human nature with our happiness.

"The real test our environment is not words,but action contribution." Although I do is just some small things,but I firmly believe that if we all have the responsibility to protect the environment,from oneself,starts from the minor matter,starts to protect our homes,to human nature will be rewarded.In the cradle of warm-a prairie; In the smiling face of the kind-growth,source of love-bathing in the river

据我收集到的一份报告说:“环境问题是由于人类不合理开发和利用自然源所造成的环境问题。红主要空气污染、水污染、噪声污染、食品污染、不适当开发利用自然资源这五大类。“我们铁的事实,他们就像一个魔鬼无情的吞噬着人类的生命。它威胁着生态平衡,危害人类健康、制约经济和社会的可持续发展,它让人类陷入了困境。为此我宣称:“只要我们不忘记,人类的环境保护意识,依法环境的意识,地球村将美丽的天堂”。深蓝色的天空的未来是必须的,水是明确的,绿色的花,可以享受人性与我们的幸福。

“真正的考验我们的环境是没有话说,但是行动贡献。“虽然我做的只是一些小事,但我坚信,如果我们都有责任保护环境,从自己做起,从小事做起,开始保护我们的家园,人类自然会得到回报。在暖和的摇篮草原;kind-growth的笑脸,在河里love-bathing来源

A lunar New Year, no doubt, is sound, taste and township.

A New Years eve firecrackers. Melody in the New Year, fireworks is low and grand drums, heavy yet explosive, accompanied by a large umbrella of scattering flowers, jinlong fall and arc of the rainbow, here every corner of the flower, a pair of, a group of cheng fang, a piece, a world, in a sudden the incomparable luster. And on the square table, and celebrate the applause, light spirit is ringing, can not help but think of "harps friend" -- it is natural to performance, the smile of gentle feeling let everyone around without his joy. Then a sound clear gong, it is in the middle of the night the cheer of the New Year, is not so short but lingering sound waves, times, stretches, like a stream, seeped into next year. In the end, a string of bells sound, it so mysterious, as if the passage of time, is at the end of the sea and the nien beast roar.

Through every form, and to have bouts of aroma. Like bacon that hard sweet, like the mutton soup hot sweet, like the natural aroma of coarse grains like steamed bread fresh incense, sweet like a sausage chewy, like dumplings a pack of sweet juice, like nuts, crisp sweet, like good old 994 stuffed sweet ChunChun... The fragrance, as they themselves. A wisp of fragrance, flavor, a dish, a table, a handful of happiness. I like dumplings, white white fat, quietly lying on the soup. It successfully, that sweet thick sesame paste, now a love heart.

JianJu the most popular cartoon "bears in the New Years day" in a situation: even if a lumberjack, also know that mothers dumplings, dads wine, are looking forward to the calendar page, end the arrival of the New Years eve. Whether its cold rime, shaking winter bamboo shoot, a speeding train, shimmering bright lights... Township, there is only one, let the wanderer to gallop tirelessly.

But you have such a scene: in the mobile phone clicking, hands of quick-frozen dumplings immodesty slide to the ground, fell to pieces, like a boom ray reminds you, want to travel to Hong Kong this year Spring Festival. So, the sound? Taste? Township?

一个春节，无疑便在于声、味、乡。

爆竹声中一岁除。过年的曲谱中，烟花是低沉而隆重的大鼓，重重的一声声爆响，伴随着大伞的散花、金龙的出落和弧形的彩虹，在这儿的每个角落一朵、一双、一群、一片、一世界地盛放，在瞬间迸发出无与伦比的光彩。八仙桌上的谈笑，与庆祝的掌声，轻灵清脆，不禁联想到“琴瑟友之”——它自然是尽情的琴声了，笑的柔和让周围的每个人都情不自己地欢欣起来。然后是一声清亮的锣响，它就是午夜时分新年的那一阵欢呼，虽短，但余音袅袅，不绝如缕，一直绵延着，就如一条溪，汩汩地流向明年。最终，有一串编钟声，它那么神秘，好像是时间的流逝，是沧海尽头年兽的咆哮。

走过每一个门洞，都有一阵阵的香飘来。像是腊肉那硬硬的香，像是羊肉汤那热乎乎的香，像是粗粮天然的香，像是馒头新鲜出炉的香，像是香肠有嚼劲的香，像是饺子一包汁的香，像是坚果干脆的香，像是陈年佳994酿醇醇的香……这香味，就如它们本身。一缕香，一丝味，一盘菜，一桌人，一捧幸福。我最喜欢汤圆，白白胖胖，安静地躺在汤里。它圆满的外表下，那甜稠的芝麻馅，宛然一颗爱心。

简举最红的动画片《熊出没之过年》中的一情景：就算一个伐木工，也懂得，妈妈的饺子，爸爸的酒，都是期待着日历的那一页，岁末除夕的到来。不管是冰冷的雾淞，晃动的冬笋，飞驰的火车，灿亮的灯光……乡，只有一个，让游子不倦地飞奔。

但是你的身边有这样的场面吗：在手机的点击声中，手里的速冻汤圆不慎滑落在地，跌得粉碎，像轰雷般提醒了你，今年春节要去香港旅游。如是这样，声呢?味呢?乡呢?

Smoke has something for people in poor health, nicotine.

Nicotine in a cigarette can kill a mouse, 25 g of nicotine in cigarettes can kill a few cows, 40 to 60 mg of pure nicotine can kill a person.

The dangers of nicotine is also quite big, it can cause stomach or other stomach disease; Also can make the person causes heart disease cause rhythm of the heart is not straight; The outbreak of serious still can cause cancer.

Cigarettes are hidden in the invisible killer, around us are all should be vigilant.

According to scientists, the chemical composition of tobacco contains hundreds of complex, most harmful to human body, including tar, nicotine, phenols, alcohols, acids, aldehyde is 40 kinds of toxic and carcinogenic substance. Smoke after the fire, smoke, contains the chemical composition of tobacco in all, at the same time than the tobacco itself and added some harmful substances, such as carbon monoxide, tobacco tar and so on. This is because in addition to the tobacco itself, in the process of cigarette made, to add some cocoa in raw materials, liquorice, sugar, glycerin, such as ethylene glycol, moist, taste fragrance and combustion-supporting material. Although these additive itself is harmless, but changed in the process of combustion. For example, in the back of the rat with cocoa after burning smoke oil, can grow skin tumor. Glycyrrhizic acid in glycyrrhiza after burning, with other ingredients, can generate have carcinogenic polycyclic aromatic hydrocarbons. Sugar increased after combustion with tobacco tar, and the product of sugar after combustion is an important carcinogens in tobacco. Glycerin and glycol after the burning of the material, not only can make smokers bladder cancer, and the acrolein inhibits the trachea and cilia secretion from the lungs, thereby increase the chances of suffering from bronchitis and emphysema, and make people with both became seriously ill.

Smoke harm to people is how great! So we cant smoke. Stop smoking, the benefit of future generations.

烟里有一种对人身体不好的东西——尼古丁。

一枝香烟中的尼古丁可以毒死一只小白鼠，25g的香烟里的尼古丁可 毒死几头牛，40至60毫克纯尼古丁可以毒死一个人。

尼古丁的危害也是相当的大，它可以引起胃痛或其它胃病;还会使人引起心律不正诱发心脏病;严重的还可能引起癌症的爆发。

香烟是隐藏在我们身边的隐形杀手，是大家所应警惕的。

据科学家测定，烟草中含有数百种复杂的化学成分，大部分对人体有害，其中焦油、尼古丁、酚类、醇类、酸类、醛类等40种是有毒和有致癌作用的物质。烟在点燃后，所产生的烟雾，包含了烟草中所有的化学成分，同时比烟草本身又增加了一些有害物质，如一氧化碳和烟焦油等。这是因为除烟草本身外，在制成卷烟的过程中，要在原料中加入一些可可、甘草、糖、甘油、乙二醇等调味、湿润、产香、助燃物质。这些添加剂虽然本身无害，但在燃烧过程中却起了变化。例如，在鼠背涂上可可燃烧后产生的烟油，可长出皮肤瘤。甘草中的甘草酸在燃烧后，与其他成分化合，可生成有致癌作用的多环芳烃。糖与烟草一起燃烧后增加了焦油量，而糖燃烧后的产物是烟中的一个重要致癌物。甘油和乙二醇在燃烧后的物质，不但可能使吸烟者患膀胱癌，而且所产生的丙烯醛可抑制气管和纤毛分泌物从肺内排出，从而增加患气管炎和肺气肿的机会，并使患有这两种病的人病情加重。

烟对人的危害是多么大啊!所以我们不能吸烟。杜绝吸烟，造福后人。

A bird in a cage, the free space is infinite, they like the frog in well spend in narrow space, not their own free life.

Each time I see them, they think, feel with the other.

Every day to stay in his own study, although the book is my partner, can let I dare not to mind empty, but sometimes standing to the window and saw the children of the same age with me on the ground to play, there is sweet smile on her face, in the heart how envy.

So, every day I see it, and have a headache, how much I yearn for freedom, I hate being at home, live a life they want, how perfect it is!!!

"The birds have belong to own sky, fish have belong to own lake, the grass has belongs to own the land, the flowers have their own sunshine, why cant I have my own life?" My time of day, but god is one of my speaker, what can he reach to me?

Freedom, how much I yearn for freedom, if one day, I walked alone in the wilderness of fragrant, let the wind blowing my hair, as the grass on my feet, as the sun on my face, I will always be walking without the light of day, when one day, I went to the sea to the sea to speak my mind, pick up a conch tell my secret about it, have a dream that one day someone picked up it, slowly to get the ears to listen to tell my story, unknowingly going the rounds and mom, dad, you may hear this story? If I understand my heart, give me a piece of my own perfect life, give me that you want freedom?

Have you heard the story?

"Sometimes, I also want to be free!" I loudly Shouting, bouts of echo in my ears. How I hope to have a free world!

关在鸟笼里的小鸟，自由的空间是无限的，它们就如井底之蛙，整天待在狭小的空间里，得不到属于自己的自由生活。

每每看到他们，便想到自己，便感到同命相怜。

每天待在自己的书房中，虽说书是我的伴侣，可以让我不敢到心中的空虚，但有时站到窗前，看见与我同龄的孩子在空地上玩耍，脸上露出甜美的微笑，心中别提有多羡慕了。

每天如此，我便看到书就心烦，头痛，我是多么渴望得到自由，我讨厌被人拘束，过自己想要的生活，该是多么完美呀!

“鸟儿有属于自己的天空，鱼儿有有属于自己的湖泊，草儿有属于自己的土地，花儿有属于自己的阳光，我为什么就不能有属于自己的生活呢?”我对天长叹，但老天只是我的一个诉说者，他又能为我达到什么呢?

自由，我是多么渴望得到自由，若有一天，我独自漫步在花香弥漫的旷野上，任风儿吹拂我的头发，任草儿在我的脚上摆动，任阳光照射在我的脸上，我始终是漫无天日地走着，当某年某日的时候我来到大海边，对着大海说出我的心事，捡起一个海螺对着它说出我的秘密，梦想有一天有人捡起它，慢慢地拿到耳畔倾听着我那诉说的故事，不知不觉地一传十，十传百，妈妈，爸爸，你们也会听到这个故事吗?是不是明白了我的心事，给我一片属于我自己的完美生活，给我那想要的自由?

你们听到了那个故事吗?

“有时，我也想要自由!”我大声地呐喊着，一阵阵的回音传入我的耳畔。我是多么希望有着自由的世界啊!
