低碳生活是一种环保、节约又时尚的生活方式。节电、节水、节油、节气可以帮助我们将低碳生活变成现实。

目前，我们的地球母亲正在“发烧”——地球变暖。而导致这次地球母亲染上这“病”的罪魁祸首就是巨大的碳排放量。不过，要治“病”也不是没有办法的。如今，低碳时代已经如约而至，正在改变着我们的生活。

其实，低碳就在我们的身边。比如：夏天，我们用空调不要用太长时间，几个小时后就关上空调，再开电风扇，这样可以省50%的电;在冰箱内放食物时，食物量最好占容积的80%，用袋子装上水制冷后放入冷藏，这样，既能延长停机时间，也能减少开机时间，更省电;经过手工DIY的再创造，你会发现原来废物也是宝，这样的家居环境健康且充满了创意的小欢乐。

平时勤动手，勤动脑，也可以实现低碳生活。平时喝茶剩下的茶叶积攒起来，可以做一个茶叶枕头;用短的铅笔，做一个笔套，套在上面，可以接着用;用肥皂剩下的小肥皂，日积月累，也能成一个肥皂。

另外，平时出行尽量步行，多骑自行车，多乘坐公交车和地铁，少开私家车;少用一次性的东西;开电脑或是电视的时间都不要太长，大约几小时就关掉。

Why do we study English, because English is the international language with the same.

When we talk about the business with foreigners, I only use English to communicate, so English is very important. If we want to understand the western culture when, must use English to understand their culture and history.

What how can we learn English well: 1, first to develop interest in English study (we can see English film from listening to English song, to find the learning interest in English). 2, English class listen carefully, as far as possible to answer the teacher#39;s questions in English, use English to communicate with classmates. 3, you can listen to English tapes of radio and television programs to imitate the pronunciation of english.

This is a good method for us to learn English well.

In addition to these methods, we can from the English books and other more effective way of learning english.

Youth is the most beautiful time to a person. When they are young and

beautiful, they can do whatever they want. Some people say that youth is the

time deserves us to be wasted, because if we are not crazy for one time, then we

will become old soon. I don’t agree with this opinion. During the most beautiful

time, we should fight for our future. The things we do will mean so much for us.

When we look back on the past days, we will be proud of ourselves. The time that

we fight for our dreams deserves to be remembered all the time. This is what

youth means to us.

As we all konw, trees have many uses.With the rapid growth of economy,the

trees has become increasingly important in our daily life.While on the one

hand,trees not only can clean the atmosphere and offer

building,desk,table,papers wood,but also making oxygen.On the other hand,trees

can prevent soil be washed away by heavy rains.In hot summer it give us shade

and make our enviroment more beautiful.So we must plant more trees and protect

forests and prevent people cut down the trees.

As we all know,the environment around us is getting worse and worse.In some places we cant see fish swimming in the river or trees on the hills.Some people even have no clean water to drink.We should live a low-carbon life in order to protect the environnment . we can go to school on foot or by bike instead of taking a car.We had better use shopping basketbets instead of plastic bags when we go shopping.We should use both sides of the paper when we write.Dot use paper cups.At our school dinning room,use our own bowls and chopsticks instead of disposable ones.We can reuse the water and save the electricity.In a word,if everyone pays more attention to our environment,there will be less pollution and our life will be better.

我们都知道，我们周围的环境越来越差。在一些地方，我们不能看到鱼在河里游泳或树木在山上。有些人甚至没有干净的水喝。我们应该过一种低碳生活为了保护环境。我们可以去学校步行或骑自行车代替开车。我们最好使用购物篮代替塑料袋当我们去购物。我们应该使用纸的两面，当我们写。不要使用纸杯。在学校食堂，用我们自己的碗，而不是一次性的筷子。我们可以利用水和节约用电。总之，如果每个人都关注环境，将会有更少的污染，我们的生活会更好。

"There is only one earth",I hope everyone will protect our environment well.

“只有一个地球”，我希望每个人都能保护好我们的环境。

人的爱好多种多样，有新奇绝妙的，有平淡无奇。我的爱好虽不新奇，但广泛得连父母都时常感叹。而在这众多的爱好之中，我还是对读书情有独钟。

爱看书还得从七年前说起。那是贪玩的我并不怎么爱看书，但有一次，从玩具堆中发现了一本被翻开的书。好奇心促使我看了下去。一下子，我马上被书中那精美的插图与那精彩的内容给吸引了。而且一发不可收拾，从此，我就爱上了读书。

长大后，懂事的我越来越爱看书了，每天都要看，少看一天都不行，成了一个不折不扣的“小书虫″。为此，我还闹出了笑话呢!记得有一次，妈妈让我烧水，烧水时，我便拿起一本书，津津有味地品读书中的精彩内容，看得忘乎所以。结果，水壶被烧坏了，搞得满屋子烟。这时，妈妈看见了，就问我怎么回事。我这时才回过神来。“糟糕!我的水呢?”妈妈见我这副模样，无可奈何地唉声叹气：唉!你这个小书虫!我提醒过你多少次了……’’

虽然我因为看书误了事,但我仍然爱读书.因为从书中,我学会了许多知识,悟出了许多道理,认识许多朋友：丑小鸭、快乐王子、孙悟空、鲁迅、冰心、爱迪生……读书还使我的作文水平提高了不少呢!

现在,书成了我每天必需的营养品,生活中没有书,就好像鸟儿没有翅膀，生命没有书,就好像生活没有阳光,书是人类进步的阶梯，书是知识的源泉!

我爱读书,因为读书使我的生活丰富多彩，使我的生命充满阳光!

我喜欢活着，生命是如此充满了愉悦。

冬天的阳光不摇，不晃，就那么直逼着，一桶一桶地倒下来。我正坐在沙发上看电视，妈妈站在阳台边玩手机。“赵倩，外面阳光特别好，你坐到阳台上来看会书吧。”妈妈喊到。“我不要，我要看电视。”我大声回复到。妈妈走到了我的身旁，语重心长的说：“你不要看电视了，你要多看点书，你语文本来就不好……”她又开始唠叨了。我不耐烦的听着。她见我没反应，直接把电视关了。我怒了，就感觉无缘无故的有一团火在往上窜。没有理由。

我走进了房间，把门锁起来了。妈妈就像扩音器一样惹得我心烦。我走到阳台边，看着外面的风景。突然有一种想法传入我的脑中：如果我从这里跳下去，会不会到另外一户人家，他们会不会对我更好?头往下仰，二十多层楼的高度，跳下去必定不会活着，我有点害怕。站在窗边好一会儿了，寒风吹得刺骨。我突然清醒到：万一我从这里跳下去，寒假过后同学们肯定会知道，我可不能让他们拿我当反面教材，我顿时放弃了这个想法。

冬天的阳光如琼浆，只管成桶地往下倒。蜡梅们也都开的差不多了。一树一树，枝枝丫丫，分不清了。

离开阳台后。我躺在床上想了好久，觉得自己实在不该与妈妈发脾气，就写了一张纸条向妈妈道歉，从门缝里塞了出去。过了一会儿，妈妈喊到：“赵倩，去学校拿成绩报告单啦!”是哦，今天要去拿成绩的，我怎么给忘了?打开房门，发现妈妈没有什么异常，我也就跟着出去了。

在路上，我有点紧张，手一直不知道该放在哪里。妈妈看不下去了，一把抓住我的手，仿佛注入了我力量，使我的心平静下来。直到走到办公室门前才松开。办公室里十分忙碌，我小声的问着杨老师分数。杨老师直接接着第二个框框给我看。我惊讶啦，竟然是第二名。我沉浸在喜悦中不能自拔，这种感觉一直延续到回家。

回家的路上，很远就看见了我家的那扇窗户。想起刚刚自己那愚蠢的想法，就觉得可笑。万一我真的跳下去啦，谁能与妈妈一起分享这第二名的喜悦。世界上有那么多癌症患者拼命地想要活下去，而那些因中考，高考失利，跳楼自杀的同学，真为他们感到寒心。生命是多么重要，它可以让你看到一切你喜欢的东西;同时生命也是十分宝贵的，一生只有这么一次。

冬日的阳光照耀着我，温暖了我的心，使我活着的每一天都丰富多彩。

我喜欢活着，生命是如此充满了愉悦。

In China, people treat the family as a very important union, families get together now and then, even the kids get married, they still treat their parents in the first place. So the family means so much to everyone, family has great influence on them.

When the family gets on well, people can focus their mind to work, they don’t need to worry about other issues. It is reported that the people live in a harmonious environment are more easy to get succeed, which reflects the importance of the family. While people who live in a unharmonious family are easily distracted from work, because besides the work issues, they also have family annoyance.

So the family is very important, we should keep in touch with family members often, even though we are busy, we should go home often, never let the work occupancies you.

在中国,人们把家庭当作一个非常重要的联盟,家人聚在一起,即使孩子们结婚了,他们仍把父母放在第一位。因此,家庭意味着太多,家庭有很大的影响。

当家庭变得很好,人们可以关注他们的思想工作,他们不需要担心其他问题。据报道,人民生活在一个和谐的环境中更容易获得成功,它反映了家庭的重要性。虽然生活在一个不合谐的家庭的人容易分心工作,因为除了工作问题,他们也有家庭的烦恼。

因此,家庭是非常重要的,我们应该经常与家人保持联系,即使我们很忙,我们应该常回家看看,不要让工作入住率。

It seems like a silly question, anyone in sane would give a hand to the elderly who fell. But in China, this question is becoming tricky. Many news report that there are some old people not just fell, they do it on purpose. Usually, they walk on a crowdy street, and pretend to faint or just lay down on the ground, intend to accuse the one who comes to help as a perpetrator and blackmail him/her for the treatment fee. Many people have fell for that and had to pay as there is no witness to prove their innocence. As for these negative news, people is afraid to help those old people in need, that makes some of them who are in real trouble could not get help in time. I once asked one of my friends: “Why the old people turn bad? If you see one in the street, would you help?” He said: “It is not the old people turn bad, it is the bad people turn old. I will video him/her to make a statement first, then decide if I would help.”

这似乎是个愚蠢的问题,任何清醒的人遇到跌倒的老人都会伸出援助之手。但在中国，这个问题变得棘手。很多新闻报道说有些老人不只是跌倒而已，他们是故意这么做的。通常他们会走到人潮涌动的街头，假装晕倒或者是直接躺在地上，想要指控那些来帮助他的人为肇事者，敲诈他们要治疗费。很多人都上当了，由于没有目击者证明他们的清白，他们被迫支付了费用。正因为这些负面新闻，人们害怕去帮助那些需要帮助的老人，也因此造成了那些真正有困难的老人没有得到及时的帮助。我曾经问我一个朋友：“为什么现在的老人变坏了?如果你在街上看到这样的老人你会帮助吗?”他说：“不是老人变坏了，是坏人变老了。我会先录像让他做一个声明，再决定是否帮助他。”

最近几天像仙境一般，那是因为雾霾，雾霾我一开始以为是普通的雾，可并不是，雾霾和雾的区别就是雾霾有毒，而雾没有毒。

In recent days, like a fairyland in general, it is because the haze, haze I thought it was a normal fog, can not, the difference between haze and fog haze and fog is toxic, no poison.

在大街上行人都戴上了口罩，虽然戴上口罩后会很难过，但是总可以挡住一点。在学校里，我们很少出去，大课间也停掉了。有些地方还因为雾霾停课了呢!

In the street, pedestrians have to wear a mask, although wearing masks will be very sad, but can block a. In school, we seldom go out big break it off. Some places also closed because of fog and haze!

雾霾最讨厌的地方就是看不见远方的风景，就像仙境一样，出去游玩也会因为雾霾而烦恼，因为高速会封道，很不方便呢!!!大家都躲在家里，希望雾霾早点散去。

The most annoying is the haze can not see the scenery in the distance, like a fairyland, go out to play also because of haze and worry, because of high speed will be blocked the road, very convenient!!! We are hiding in the home, hope the haze dispersed as soon as possible.

以前是没有雾霾的，现在却有雾霾了。为什么会有雾霾呢，那是因为现在的坏境。只有我们保护好环境，雾霾就会变成没有毒的雾了。请大家保护好环境，让雾霾消失吧!

There is no haze, haze now. Why haze, it is because of the bad environment. Only we protect the environment, the haze will be no toxic fog. Please protect the environment, let the haze disappeared!

I have learned English for many years, but I don’t have a chance to speak foreigners before.

last week, I happened to encounter a foreigner, I felt so excited, he needed my help. It was on Monday, I went to the flower shop to buy a flower for my friend, because she was ill, I was going to the hospital to see her. Then a foreigner and the boss were having conversation, but the boss didn’t know what the foreigner said, I hesitated for a while, then I came to help the boss.

The boss and the foreigner thanked me so much, I felt so happy, the language I learn is useful. Since then, I want to learn English well.

我学习了英语已经很多年了，但是我之前都没有机会和外国人说话上周，我碰巧遇到了一名外国人，我觉得很兴奋，他需要我的帮助。那是星期一，我去花店买花给我的同学，因为她生病了，我准备去医院看她。然后一位外国人和老板在聊着，但是老板不懂外国人的话，我犹豫了一会，然后我开始帮助老板。

老板和外国人很感激我，我觉得很开心，我学到的语言终于派上用场了。从那时起，我想要把英语学好。

Last weekend, I travelled in Hong Kong. Hong Kong is a very beautiful modern city, it’s to the south of Guangdong. There are many tall buildings and wonderful places to visit, such as: Victorian Park(维多利亚公园), Disneyland park(迪士尼乐园). What I like best is to visit the Ocean Park(海洋公园). The Ocean Park is the biggest recreation center(休闲中心) in the southeast of Asia(东南亚), each year many people go there to pay a visit. We saw many performances by the dolphins and the whales. The performances were very exciting and the animals were very lovely. We really had a good time in Hong Kong.

How I Spent My Summer Vacation

I spent this summer vacation in quite a different way.

I used to run about every day in previous summer vacations,this summer vacation I simply could not afford to do so.

I would soon be in the last year of my high-school education would after graduation be up against the college entrance examinations.

Though those examinations were still a year away, I had to start early to make myself well prepared by reviewing all those things I had learned at school this summer vacation was the ideal time for me to do this.

At first I was rather dismayed at the thought of this,8ttt8.

comlater I thought it was better this way because by working hard this summer I could count on endless happy summers to come.

With this in mind I then set to work like anything and occasionally went out for a change or did some physical.

I was not at all bored by this kind of life, for I was sustained by a hope.

I like reading very much. When I was a small girl, I was interested in

reading picture books on science and history. At the age of seven, I entered a

primary school and began to read more books.

Now I am a middle school student. I have many subjects to learn. Every day

I must finish a lot of homework. I am very busy. But when I have spare time I

still want to read some story books. One day my young sister brought me a book

Xl YOU JI.I read the book with great interest. I like Monkey King very much.

In addition to tension, enrich the study life, I also have a relaxed, enjoyable holiday. The rich content, enriched my life, as well as childish students career added a few minutes of fun and carefree.

At ones go for a walk after dinner is my daily required course. Stroll near the village of flowers and plants, breathing the fresh air, and the bird companion, to enjoy a rich rose, lily of the noble and pure, strange flowers, dinner and beautiful magnolia, cannas brilliant, I will gently said to myself: "life is beautiful." I use the sincere feeling around colorful, with enthusiasm to appreciate the very beautiful flowers around us. I spontaneously from the heart: "I, belong to nature!"

More to the book, I will plunge into the ocean, breathing the smell of the fragrance of bookstores, libraries specific, experience the fun of walking books. Into the ocean of history, qin shi huang burying Confucian behavior and anger, would I be for farewell my sad tears, for the various ge is bright "teacher heel dead" untimely. Stroll the palace of literature, I gradually realize the treasure chai helpless, dai jade talent, experience of Marys stubbornness, colin weak, experience of the early morning rain listen "yu, qian zhongshus" fortress besieged "...

My summer vacation life, is a poem, a green leaf, a song...

除了紧张、充实的学习生活外，我还拥有轻松、愉快的假期生活。那丰富多采的内容，充实了我的人生，也为童稚的学生生涯增添了几分乐趣与悠然。

茶余饭后去散步是我每天的必修课。漫步在小区的花草旁，呼吸着清香的空气，与花鸟作伴，欣赏着玫瑰的浓郁，百合的高洁，晚饭花的奇特，还有玉兰的娇美，美人蕉的绚丽,我会轻轻地对自己说：“生活真是美的。”我用真诚感受身边的五颜六色，用热情欣赏周围的姹紫嫣红。我不由自主地从内心发出：“我，属于大自然!”

更多地，我会一头扎进书的海洋，呼吸着书店、图书馆特有的那种书香的气味，感受漫步书海的乐趣。钻进历史的海洋，我会为秦始皇焚书坑儒的举动而激愤，为霸王别姬的悲惨而落泪，为诸葛亮“出师未捷身先死”扼腕叹息;漫步文学的殿堂，我渐渐体会到宝钗的无奈、黛玉的才华，体会到玛丽的倔强、科林的孱弱，体会到余秋雨的“晨雨初听”、钱钟书的“围城”……

我的暑假生活，是一首诗，一片绿叶，一支歌……

Lost time is never found again. This is something which I learned very clearly last semester. I spent so much time fooling around that my grades began to suffer. I finally realized that something had to be done. It was time for a change. Now I have a new plan for using my time wisely. I have set my alarm clock ahead half an hour. This will give me a head start on the day. I have also decided to keep a log of what I do and when I do it. Looking back on what I’ve done will give me some ideas on how to reorganize my time.

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。
