新学期的开始，每一位同学都会从新开始认识自己的老师，而我也不例外。

我的英语老师是一个又瘦又帅的人。他讲课时，会有几分钟的玩笑时间，所以我们班的每个同学都喜欢他的英语课，而他也不喜欢我们在他的课上表现出昏昏欲睡或者是整个班死气沉沉。如果那 样，他会很不高兴，从而不给我们讲课。

因从我们每一个人都不会这样做的，而且会紧绷着自己的神经，生怕会在他的课上犯困。但如果我们让他高兴了，他会很高兴上我们的课程，而且会给我们讲笑话，逗得我们哈哈大笑，使得课堂气 氛非常活跃。

而这就是我的英语老师。

Many holidays are there in a year, with Chinas traditional holiday, have belong to our festival - the childrens day, May Day, ten first-class legal holiday. But my favorite is not the holiday, but Christmas.

Christmas is a holiday for all Christian countries in the world, commemorates Christ birth festival. Although it is not important to Chinese people, but we can still see Christmas brings to life change. First of all, some stores began with Christmas sales, shop front were filled with Christmas and related commodity: reindeer! Santa Claus toy! Has become a sale of goods, and was deeply loved by consumers. Second, the school also has carried out many Christmas activities, guess what gift, Christmas party, give a person a kind of strong festival atmosphere. Christmas is coming slowly.

I love the atmosphere of Christmas is not only love it, but also want to get their Christmas presents. Every year on Christmas Eve, I sat quietly, eyes staring at the shining stars in the night, the in the mind with hope, hope that his next day could make every dream come true. I remember last Christmas, I want to get a pen wish, result the second day morning, a new pen is in my bed, I was overjoyed, hurriedly to the big news to his mother, ask her what is going on. Can be looked at his mother confused look in the eyes, a mysterious thought crossed my mind, dont Santa Claus really exist?

Yes, in my opinion, Christmas is just such an atmosphere, full of mysterious festival. And it also inspires me cherish the time, but once a year at Christmas. Every time, is also a significant and we are one year older again, in a year. Do you have any harvest. Have what experience. Whats the shortage and progress? We will be more Christmas as a learning meeting, as a Christmas present for a good years encouragement, the blessing as a spur for next year, its not better?

Christmas with me grow up, I love Christmas!

一年有许多的节日,有中国传统节日春节,有属于我们的节日----儿童节,还有五一,十一等法定节假日.不过我最喜欢的不是这些节日,而是圣诞节.

圣诞节是世界上所有基督国家的节日,是为了纪念耶署基督诞生的节日.虽说它并不被中国人所看重,可我们仍然能看到圣诞节给生活带来的变化.首先,一些商家开始用圣诞节作推销,店铺门前摆满了和圣诞有关的商品:驯鹿呀!圣诞老人玩具呀!都成了特卖商品,也深受广大消费者的喜爱.其次,学校里也开展了许多圣诞活动,什么猜礼物,圣诞晚会,给人一种浓郁的节日气氛.圣诞节就这样慢慢地来临了.

我爱圣诞节不是只爱它的氛围,更是想得到自己的圣诞礼物.每年的平安夜,我都会静静地坐在,眼睛凝望着一颗颗在黑夜中闪烁的明星,心里带着期盼,希望自己第二天能够让自己的每梦成真.记得去年圣诞节,我许下想获得一只钢笔的愿望,结果第二天早上,一只崭新的钢笔就出现在我的床头,我喜出望外,赶紧将这个天大的消息告诉了妈妈,问她是怎么回事.可看着妈妈疑惑的眼神,一个神秘的念头闪过我的脑海中难道圣诞老人真的存在吗?

是的,在我看来,圣诞节就是这样一个氛围浓厚,充满神秘的节日.而且它也激励着我珍惜时间,一年只有一次圣诞节.每过一次,也就相当与我们又长大了一岁,一年里.你有什么收获.有什么经验.有什么不足和进步?我们更能将圣诞节当作一次学习的总结会,把圣诞礼物当作对好的一年的鼓励,把祝福当作对明年的鞭策,这不更好吗?

圣诞伴我成长,我爱圣诞节!

Remember when I was three years old is four wheeled bike ride, then see other children on two wheels of the bicycle, I also want to ride. But in the heart of demons how also wont disappear, always afraid of hurt, afraid of ke is hurt. Mom and dad gave me great encouragement, and finally the two small wheeled off and ride up and not focus, always stagger, two feet without leaving at the same time. Havent contact for a while, I like frustrated the ball, pursed mouth. Mom and dad to see me so soon discouraged, told me a lot of truth, I also dont listen. Finally mom and dad use a meter, let me quickly learned to ride a bike.

Mom and dad pushing his bike out, riding up and said to me: "tingting, my mother and I want to ride a bike to go out to play, goodbye!" I have a look at mom and dad to go and ride a car chase, said: "you dont go, wait for me." This is mom and dad just stopped and looked at me and smiled. I immediately stopped, hugged daddy, said to him: "dad, I can ride a bike."

So, I learned to ride a bike, and after I hard practice, I mastered the skills in less than a week. Our family bicycle went out to play.

"Difficulties like spring, you weak it is strong. Difficulties like spring, you strong it is weak."

I through that finally understand this truth, to insist, can not fall by the wayside. Must eat to the success of sweets!

这个世界上有许许多多的困难，克服了就吃到了成功的糖果，失败了就吃到很酸的酸梨，在我三岁时，就尝到了成功的糖果。

记得我三岁时骑的是四个轱辘的自行车，那时看到别的小朋友都起两个轮子的自行车时，我也很想骑。可是心中的心魔怎么也消失不了，总是怕摔着，怕磕疼了。爸爸妈妈给了我很大的鼓励，最后把两个小轱辘卸掉了，骑上去没有重心，总是东倒西歪，两只脚没有同时离开地的时候。还没联系一会儿，我就像泄了气的皮球，撅起了嘴巴。爸爸妈妈看我这么一会儿就泄气了，给我讲了好多道理，我也听不进去。最后爸爸妈妈使用一计，让我很快学会了骑车。

爸爸妈妈也把自己的自行车推了出来，骑了上去并对我说：“婷婷，我和妈妈要骑车出去玩了，再见啦!”我一看爸爸妈妈要走，一边骑上车追，一边说：“你们别走呀，等等我。”这是爸爸妈妈才停下来，看着我，会心的笑了。我立刻停了下来，抱住了爸爸，对他说：“爸爸，我会骑车了。”

就这样，我学会了骑车，经过我刻苦的练习，我不到一个星期就掌握了技巧。我们一家子骑车出去玩了。

“困难像弹簧，你弱它就强。困难像弹簧，你强它就弱。”

我通过那件事终于明白了这个道理，做事要坚持，不能半途而废。一定要吃到成功的糖果!

我们人类生活在地球上，地球上有许多东西需要我们保护，但是我们却没有在意。

We live on the earth, the earth there are many things we need protection, but we didnt care.

有些人不珍惜地球赐予我们的一切，例如人们乱砍乱伐，大量使用一次性筷子和乱扔塑料袋，制造白色垃圾等已经给大自然带来了许多环境问题，严重影响了我们的生活。还有大气污染，酸雨和臭氧层等带来的危害都是大自然给人类带来的灾害，人们乱砍乱伐，乱扔塑料袋和使用一次性筷子等，这些就是人们不尊重大自然而造成的，没有自然，便没有人类。这是世界一大朴素的真理，人们只会一味的抢夺自然，征服自然，只会破坏生态系统，咎由自取，使人类濒于困境。切记，保护环境就等于保护我们自己生存的环境。

Some people do not cherish the earth gives us all, for example, people cut down many trees, the extensive use of disposable chopsticks and throw plastic bags, producing white garbage has to nature brought many environmental problems, a serious impact on our lives. There are air pollution, acid rain and the ozone layer damage caused is human nature to bring disaster, people cut down many trees, throw plastic bags and disposable chopsticks, which is that people do not respect the nature and cause, no nature, no human beings. This is a big world, plain truth, people just blindly grab the nature, conquer nature, will only bring trouble to oneself, the destruction of the ecological system, humans dilemma. Remember, Protect environment is to protect our own living environment.

我们要保护这个脆弱的的地球，不要让茂密的森林，辽阔的草原和无边无际的海洋成为我们的回忆。

We want to protect this fragile earth, dont let the dense forests, vast grasslands and boundless ocean has become our memories.

现在起，我们应该保护环境，一起捍卫我们的家园。

Now, we should Protect environment, to defend our homeland.

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。

Dear Sara,

I’m glad to receive your letter. Thanks for your caring for the weather and my health. Now I’d like to tell you something about the smog in Jiangxi.

Up to now, the smog has occurred many times, which has done great harm to our daily life. Many traffic accidents have happened. Quite a lot of flights have to be put off. Many people have to stay at home for fear of the poisonous air caused by the smog.

People have realized the great harm caused by the smog and the importance of protecting the environment. People are taking measures to reduce the smog weather. The government suggests people go to work or school with the public traffic. Also we should plant more trees.

As for me, I’ll go to school by bike or on foot. In addition, I will tell people around to protect the environment as possible as they can. Would you like to tell me some good ideas?

Looking forward to your reply.

亲爱的萨拉,

我很高兴收到你的来信。谢谢你的关心天气和我的健康。现在我想告诉你一些关于江西的烟雾。

到目前为止,烟雾发生很多次,我们的日常生活造成了极大的伤害。发生了很多交通事故。相当多的航班不得不被推迟。很多人都呆在家里,因为怕有毒的空气所造成的烟雾。

人们已经意识到造成的极大危害烟雾和保护环境的重要性。人们采取措施,以减少烟雾天气。政府建议人们用公共交通上班或上学。我们应该种植更多的树。

至于我,我将骑自行车去上学或步行。另外,我要告诉周围的人尽可能的保护环境。你愿意告诉我一些好主意吗?

期待你的回复。

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。

地球是我们的家园，我们应该保护地球。现在有的地区已经出现了泥石流、台风、森林火灾、小河污染、臭氧层破坏、空气污染……我们已经不断遭受来自大自然的惩罚。

The earth is our home, we should protect the earth. Now in some areas there have been landslides, typhoons, forest fire, river pollution, destruction of the ozone layer, air pollution...... We have to continue to suffer from the nature of the punishment.

我们怎样才能保护我们的家园呢?我们要多种树，不乱砍伐树木，不乱扔垃圾，讲究卫生，保持校园干净。多种花草，节约用水，保护动物，不破坏水源……我们还要说道做到。我们要让为来的生活变成水源丰富，绿树成荫，没有沙漠，没有天灾，海底物产多，草坪面积更大……让我们的环境变美、变净、变绿，环境更优美。

How can we protect our homeland? We should plant more trees, do not indiscriminate felling of trees, do not throw garbage, pay attention to health, to keep the campus clean. A variety of flowers and plants, water conservation, protection of animal, no damage to water...... Said we must do. We want to become rich in water resources, living trees, no desert, no disaster, marine products, lawn area larger...... Let us change the environment, change the net, greener, more beautiful environment.

保护环境，人人有责!只有我们每个人都奉献出自己的一点点环保，就能使明天的家园变得更加美丽。

Protect environment, everyones responsibility! Only when each of us to give a bit of environmental protection themselves, can make the home more beautiful tomorrow.

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。
