Every year, when the college entrance exam is over, students will be very

happy and feel relieved, so they will throw away books to show the hard journey

is over and the new chapter has opened. Most young people need to face the

college entrance exam. It seems that the years’ hard working is expected to

deserve a good result. Before the result comes out, students will celebrate by

hanging out all the night, such as go to KTV with their friends. Without the

pressure of study, they feel great joy. This is the unforgettable memory for

most people. No matter how old they are, they will never forget about the crazy

days of youth. The long-term year’s study and fighting for the future with their

classmates make their youth become special.

Our world is originally mountains, vast sea is blue, the vast sky is blue, the earth on which we live there are so many beautiful scenery, let us can not help but to admire the beauty of this world.

In this world there are ten million species of creatures, they get along, together in this live on the earth like a sapphire, tens of millions of years, too, will not change. But there is a kind of biological change the world, it is in this world with his proud technology to kill themselves, it is human. Human beings in this world only live for one million years, but it such as brute kills life on earth! In 2009, the Indian da-hong ruined homes of five million people in one hundred; In 2010, the Haitian earthquake left two hundred and thirty thousand people dead, according to estimates that by the year 2050, there will be two hundred and fifty million ecological refugees, we use our knowledge to kill themselves, as a human, I think its ironic.

The earth is in the vast universe, the only planet to harbor life, originally the earth is green hills and water, a piece is abundant, but todays earth after hurricanes, forest fires and drought in high temperature, is about to collapse, the earth began to shout for us, in the 2010 years, the earth has used its roar to kill two hundred and thirty-six thousand people, the earths voice we should hear, or the end of the world will come in advance.

Close to one end of the alarm, have "lungs of the earths forest gradually reduce, the earth began to collapse, there is only one earth, and this one belongs to you, rather than a human, the earth is our refuge, we should find a balance point and the earth coexistence, reduce the anger of the earth, let the human is no longer increase driver disaster, let us have a better living environment, but also for generations to leave some more living space.

我们的世界本来是青山绿水，汪洋的大海是湛蓝的，广阔的天空是蔚蓝的，我们居住的地球有太多美景，让我们不禁要赞叹这世界的美丽。

在这个世界上有千千万万种的生物，它们相处融洽，一起在这如蓝宝石般的地球上生存，过了几千万年也是一样，不会改变。但是有一种生物的出现改变了整个世界，它在这个世界用自己引以为傲的科技杀死自己，它就是人类。人类在这个世界上只生存了百万年，但是它却如猛兽般的杀死地球上的生物!在二零零九年时，印度百年大洪水毁了五百万人的家园;二零一零年，海地大地震让二十三万人死亡，根据估计，到了二零五零年，将会有二亿五千万名的生态难民，我们用我们的知识杀死自己，身为一个人类，我觉得很讽刺。

地球是在浩瀚宇宙之中，唯一能孕育生命的星球，本来的地球是青山绿水，一片盎然，但是现今的地球经过飓风、森林大火和高温干旱等严酷的考验，已经快要崩毁，地球开始对我们怒吼，在二零一零年时，地球已经用它的怒吼害死了二十三万六千人，地球的心声我们应该要听见，否则世界末日将提前来临。

末日的警钟一分一秒的接近，有“地球之肺”的森林逐渐的减少，地球开始崩毁，地球只有一个，而且这一个属于大家，而不是人类的，地球是我们的庇护所，我们应该找到一个和地球共存的平衡点，减少地球的怒气，让人类不再是加重灾难来临的推手，让我们有更好的生活环境，同时也替后代子孙多留一些生存空间。

天蓝白云伴，风轻阳光暖。白的叶，绿的草，专属于美好的绿色校园。当我们正做着自己的事的时候，是否曾设想有一天我们将失去这个美丽的校园?

The Great Wall runs across North China like a huge dragon, It winds its way

from west to east, across deserts, over mountains, through valleys till at last

it reaches the sea. Its the longest wall on the earth, also one of the wonders

in the world.The Great Wall has a history of more than 2000 years. The first part was

built during the Spring and Autumn Period.

All the walls were joined up in Qin Dynasty.All tile work was done by

hand.Thousands of people died while building the wall.Thus the Great Wall came

into existence.Since then, it has been rebuilt and repaired many times.

Now the Great Wall,the admiration of the world, has taken on a new look.

Its visited by large numbers of people from all parts of the country and the

world.

As the whole world has its boundaries, limits and freedom coexist in our life. I dont expect complete freedom which is impossible. I simply have a dream that supports my life.I dream that one day, I could escape from the deep sea of thick school books and lead my own life. With my favorite fictions, I lie freely on the green grass, smelling the spring, listening to the wind singing, breathing the fresh and cool air and dissolve my soul in nature at last. Simple and short enjoyment can bring me great satisfaction.

I dream that one day the adults could throw their prejudice of comic and cartoon away. They could keep a lovely heart which can share sorrow and happiness with us while watching cartoon or doing personal things. Thats the real communication of heart to heart.

I have the belief that my dreams should come true. I am looking forward to some day coming when I am like a proud eagle which flies to the blue and vast sky.

今天早上，我起了床，吃完了早饭，就去上特长班了。

下楼打开门一看，外面全都是雾，而且雾还很浓。走进雾里，一股清冷潮湿的空气扑来。我坐上了车子，准备去学特长。在雾里待久了，一些顽皮的小水滴镶嵌在我的衣服上。我向四周望了望，顿时想出了一个奇特的想法：我好像走进了《西游记》中的瑶池?这雾像是走进了神话一般!雾的景象真美呀!路上，姥爷问我：“这是雾还是霾?”我说这是雾，姥爷又说：“不对，是雾和霾都有。”

但雾霾对身体有害。雾霾天气不仅影响市民出行，也对市民的身体健康也有影响。雾霾天气空气流通性差，空气质量也差，雾霾中的有害物质会引发一些疾病，对健康人会轻微的器官损伤，还咳嗽、痰多……

所以，雾霾天气要少出门，出门的话要戴口罩、饮食清淡多喝水、雾霾天气少开窗……

雾霾跟我们的污染有关系，所以我们要珍惜大自然。

据研究，美国空军战斗机失误频繁的一个重要原因是驾驶舱是按照飞行员身体特征的平均值设计的。可飞行员不是按平均值生长的，当他们必须在少于半秒钟内做出判断和行动时，平均值系统和操作员之间的矛盾就容易导致一系列事故。后来，美国空军要求制造商改变设计，让座舱能随飞行员的个体特征做局部调整，让系统适应个人。此后战斗机事故率降低，作战水平也得到了提升。

Human, science and nature, the three phase was quoted rates are inseparable. The wonders of nature, a little thing, through the baptism of the time, and meticulous observation, often can give a person with enlightenment.

Vast forests, sunshine give plants grace, to be able to get the nutrients and thrive. Such as the morning sun open the eyes of animals, everything is ready. Squirrels, squirrel, embarks from the house, looking for full sweet red pine nuts, all kinds of plant seeds and slowly by seeding them to other places. While the weasel feed on smaller herbivores, sable and then ate the weasel... As if people eat the big fish, big fish eat small fish, small fish eat shrimp, shrimp eat plankton, interlocking between RACES, interdependence restricts each other.

Foreign scientists have done an experiment: introduce the sheep in a rare nature reserve, where the bamiyan, natural environment is superior, and there is special personnel to the group of kids to their natural enemies, Wolf, moved to another place. So the sheep started in the breeding. Until grass and low shrubs are eaten, the number of sheep instead of less. Because they live too comfortable, there is no enemy attack, the number that is too carefree life let their constitution also fell. Then the scientists tried to introduce wolves again. The result is in the relationship between predator and prey, good robust species to survive, wolves eat sick defect part. Natural selection and evolution, has been the nature and even the survival of human society the same criteria.

Cut down some trees, is to destroy a part of birds and insects; Killing of bees, small fish, can also cause cannot spread pollen, fish cannot reproduce problem... Sabotaged a part of the food chain, will bring ill-defined disaster. Because in front of the natural fair, each species, each independent individual organisms is so beautiful and full of value.

Because of the diversity of species and colorful nature. Want to live in harmony with her and get the kind of treatment, will be good to nature, to understand the nature, and have good at discovering and innovative mind.

人类、科学、自然，这三者相生相息密不可分。大自然的奇妙之处在于：一件小小的事物，经过时间的洗礼以及细致入微的观察，往往能给人以启示。

广袤的森林中，阳光雨露给予植物恩泽，使其能够得到养料然后茁壮成长。等清晨的阳光掀开动物们的眼睛，一切也准备好了。松鼠、灰鼠从居所里出发，寻找饱满香甜的红松子，各种植物的种子于是慢慢的被他们带到其他的地方落地生根。而此时黄鼠狼以体型较小的草食动物为食，紫貂继而吃掉了黄鼠狼……就好像人吃大鱼，大鱼吃小鱼，小鱼吃虾米，虾米又吃浮游生物一样，各种族之间环环相扣，相互依存相互制约着。

外国的科学家曾做过一个实验：将一种稀有的羊引进自然保护区，那里水草丰美，自然环境优越，并且还有专门的人员为这群天之骄子将她们的天敌——狼，迁往另外的地方。于是羊群开始在此生息繁衍。直到草和低矮的灌木被吃光了，羊群的数量反而越来越少。原来是因为它们生活的太过安逸，没有天敌进犯，数量过于膨胀，太过悠闲的生活让它们的体质也下降了。后来科学家们尝试着再一次引进狼群。结果是在捕食者与猎物的关系中，健壮优良的品种得以存活，狼群则吃掉病弱残疾的部分。物竞天择，优胜劣汰，一直都是自然界乃至人类社会不变的生存准则。

砍掉了某种树林，就等于灭绝了一部分鸟类、昆虫;捕杀蜜蜂、幼小鱼类，也会造成花粉无法传播，鱼群无法繁衍的问题……大肆破坏生物链中的某一环，都会带来难以言说的灾难。因为在公平的自然面前，每个物种，每个独立的生物个体都是如此的美丽而富有价值。

大自然因为物种的多样性而五彩缤纷。想要与她和谐相处并得到其慈祥的对待，就要善待自然，了解自然，并拥有一刻善于发现与创新的心。

As we all know water plays an important part in peoples daily lives. More and more water is needed in the modern society. So we should try to save it.

Now many places are short of water. For example, a big drought hit the Southwest of China at the beginning of this year. especially Yunnan province, milions of people has not got enough water for common life. A lot of rivers and lakes are polluted. Whats worse, many people are wasting water seriously.

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

我们都知道，水在人们日常生活中，扮演重要的角色。现代生活中，我们需要越来越多的水，所以我们应该保护它。

现在很多地方缺水，今年年初在中国西南部就发生严重的干旱，特别是云南地区，数以万计的人们没有充足的水资源供日常使用。很多河流湖泊被污染，更严重的是，人们对水浪费严重。

为了保护水资源，让我们付出行动抵制水污染和浪费的行为吧。
