我读了一本外国名著——《雾都孤儿》。它的作者是英国著名的现实主义作家狄更斯。书中的内容很精彩，让我着迷。

书中的主人公是一个孤儿，名叫奥利弗·特维斯特，这本书讲述了奥利弗小时候的故事。他出生在孤儿院，在那儿受尽了欺凌后，被卖到了一个殡仪员的家庭。可是，因为有一次殡仪员误解了他，狠狠地打了他，所以他就逃到了传说中美好的伦敦。但是到了伦敦后，他又不幸陷入了贼窟。

尽管他的遭遇如此悲惨，他却最终坚强地活了下来。在好心人的帮助下，他解开了自己的身世之谜，找到了自己的姐姐，与姐姐相依为命。奥利弗终于有了亲人的关怀和帮助，我也为他感到庆幸。

那时的伦敦有很多穷人，他们都饱受过欺凌，甚至到了走投无路的境地。于是，有的为了生存，就去当强盗，做小偷……他们都没有像奥利弗一样——坚守着心底深处的纯净。奥利弗相信，只有这样，才能为自己找到出路。

《雾都孤儿》让我学会深思，给了我很大启发。它是我读过的第一本大部头外国名著，我要好好地珍藏这本书。

When it comes to haze, I believe many people hate it to the bone and sigh

when talking about it. No, just a few sunny days, Monday morning gave us a big

"surprise".

In the morning, as soon as I stepped out of the door, I was stunned by the

scene in front of me: the sky seemed to be covered by a gray cloth, and the

pedestrians, roadside plants and cars on the road were also dyed gray.

Everything is covered with a layer of ash. Walking on the street, the visibility

is less than 100 meters. Under the influence of haze, the original clear scene

becomes extremely blurred. Even the bright colors of the traffic lights seem to

be in a trance.

At school, the situation has not changed, and low temperature is of no use.

The red flag is flying in the middle of the air. The soft and beautiful

movements are slightly slow due to the influence of the dust around. Because in

haze days, many small particles will be inhaled, and the oxygen content in the

air will be reduced, which is not suitable for sports, so the physical education

class in the morning has also been cancelled. I dont know if I should be happy

or worried.

Haze days, its really annoying!

Christmas is the most important festival in the western world. It falls on

December 25th. When my mother and I stayed in America, we were invited by one of

my mothers friends to have Christmas with an American family. We bought some

presents for our American friends on our way to their house.They had prepared

different kinds of gifts for their family and guests when we got to their house,

such as Christmas candles, cakes, cards, little toys, biscuits and so on. A

Christmas tree was placed in the comer of the brilliant hall. How beautiful it

was! We were impressed by these. We had a big meal. After dinner, they told us

some interesting stories about Christmas. We learned that Christmas had

something to do with God. We went to bed at midnight. Though we knew the Santa

Claus was not true, we were still waiting for the Santa Claus with white beard

to bring us presents.And we received many beautiful presents the next

morning.This Christmas was really unforgettable. Not only did I have a good

time, but also I knew something about foreign culture.

In every year the end of June, it is the beginning of my precious summer holiday. Last summer, I had a great holiday. Firstly, I spent only a week to finish all my summer homework. Then I have still almost two months to do anything I wanted. Actually, I really did what I wanted to do in last summer. I traveled to beijing with my best friend for 2 weeks. We were so happy and the trip was just perfect. In the rest of my holiday, I did not do anything even related to study. Everything is all about games. However, I will not have a chance to spend my summer holiday like the last one. There is much more homework that I have to use probably three quarters of my holiday to finish it. If there is not so much homework, I might have my ideal summer holiday in this year. My ideal holiday is that go to the beaches in México with my family. For about a whole month we can completely relax in the beautiful beach. In the morning, after the delicious México style breakfast, we can walk along the beach while enjoy the beautiful morning sunshine. In the afternoon, we can have the freshest seafood for lunch. After lunch, take a nap in the sunshade would be the best thing to do. At dusk, there is the most gorgeous sunset on the sea... I love the beach, I love summer holiday.

The Chong Yang Festival is celebrated on the ninth day of the ninth lunar month, and it is as such known as the Double Ninth Festival.

Climbing mountains: On the Double Ninth Festival, people customarily climb mountains, appreciate chrysanthemum flowers, drink chrysanthemum wine, and eat double-ninth cakes. The Double Ninth Festival is also the Old Men Festival. Old people are especially meant to improve their health by taking part in the activities on the day of the festival.

Origins: The festival began as early as the Warring States Period (475 - 221 BC). According to the yin/yang dichotomy that forms a basis to the Chinese world view, yin represents the elements of darkness and yang represents life and brightness. The number nine is regarded as yang. The ninth day of the ninth month is a double yang day, hence the name Chong Yang Festival. (Chong means repeat in Chinese.) The ninth month also heralds the approach of winter. It is a time when the living need warm clothing, and filial Chinese sons and daughters extended this to make the festival a time for providing winter clothes for their ancestors. The Double Ninth Festival, therefore, also became an occasion to visit the graves of dead family members. Clothes made of paper would then be burnt as offerings.

Family get-togethers: The Double Ninth Festival is also a time for family get-togethers. It is an occasion to remember one‘s ancestors, the sacrifices they made and the hardships they underwent. Often, family outings are organised during which people search to renew their appreciation of nature and to reaffirm their love and concern for family members and close friends.

雾霾天气是自然和人为污染环境所形成的，面对这种恶劣天气，我们只有采取各种措施尽量避免其给人们正常生活和健康带来的危害。

1.减少外出。抵抗力弱的老人儿童以及患有呼吸系统疾病的易感人群应尽量减少出门，或减少户外活动，外出时戴口罩防护身体，防止污染物由鼻、口侵入肺部，外出归来后，应立即清洗面部及裸露肌肤。

2.减少户外锻炼。雾霾天气气压低，能见度低，空气中悬浮大量尘埃等有毒颗粒，患有支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸道疾病患者，应尽量避免户外锻炼，以免诱发慢性病得发作或加重。同样大雾天气压较低，高血压、冠心病等慢性病患者不宜做户外锻炼，以避免诱发心绞痛、心衰。中等和重度霾天气易对人体呼吸循环系统造成刺激，尤其是在早晨空气质量较差。通常来说，若无冷空气活动和雨雪、大风等天气时，锻炼的时间最好选择上午到傍晚前的空气质量好，能见度高的时段进行，地点以树多草多的地方为好，霾天气时也应适度减少运动量与运动强度。

3. 关闭门窗。由于雾霾天气时，空气中的污染物难以消散，在大雾的天气应紧闭门窗，避免室外雾气进入室内污染室内空气，诱发急性呼吸道和心血管疾病的发生。

4. 注意饮食。患有慢性呼吸道疾病患者，尤其是老年人要保持科学的生活规律，避免过度劳累，多饮水。要注意饮食清淡，少食刺激性食物，多吃些豆腐、牛奶等食品，必要时要补充维生素D。

5.行车走路要倍加小心。中等和重度雾霾天气下，能见度较低，视线差，驾车、骑车和步行的人们都应多加小心，特别是通过交叉路口和无人看管的铁道口时，要减速慢行，遵守交通规则，避免发生交通事故。

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive. Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. We are sure that we can have a better and cleaner place in the future.

今天,我们的自然环境质量已经成为一个重要的问题。世界人口增长如此之快,世界已变得过于拥挤。我们正在利用我们的自然资源,同时与危险化学品污染我们的环境。如果我们继续这样做,地球上的生命将无法生存。关注人在环境保护方面取得了一些进展。许多国家的政府已建立法律来保护空气,森林和海洋资源并停止环境污染。

更应该采取措施解决环境问题。人们应该进一步受过教育的认识到问题的重要性,使用现代避孕方法,来保护我们的天然资源和循环利用我们的产品。我们确信我们能在未来有更好的和更清洁的地方。

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.

Being humble and tolerant are believed to be traditional merits in China,

so many people get used to keep silent when they meet unfair situation, because

they think things will be solved as time passes. Actually, it only makes things

become worse, especially to make the criminal situation increase. Recently, a

girl was offended in the high speed train, and most people would choose to

pretend nothing happened, because they did not want to make things become

complicated, but the girl chose to call the police and let her voice out. The

public supported the girl and many people said they met the same situation. It

was time to give some punishment for these bad guys. If we meet unfair

situation, it is necessary to let our voice out and bring the criminal guys to

justice. The society will be much more harmonious.

In recent days, the sky is very gray, can not see the sun, give a person a kind of chilly. You see: close, plant area of two cooling towers, looming; In the distance the mid-levels, gone. Also let a person mental laziness, depressed all day. Newspapers, television publicity: recent haze, out less and less as far as possible to open a window. Visible haze serious air pollution, the air quality to drop, affect human body health. I would like to know the fog haze and its harm to people, then go online to check, it was "dont know, a look startled!"

There are hundreds of different fog atmospheric chemical composition of particulate matter. Among them include: organic aerosol particles, fuel, and automobile exhaust. It can directly enter and adhesion in the human respiratory tract and alveolar, cause acute rhinitis and acute bronchitis. For obstructive emphysema, bronchial asthma patients, such as fog weather condition of acute attacks. If this kind of environment for a long time, will also cause cancer.

It have an impact on the cardiovascular system. Pollutants in haze weather, low air pressure, easy to cause acute episodes of cardiovascular system. Such as heavy fog, the water vapor content is high, if people in the outdoor sports, can cause chest tightness, high blood pressure and other symptoms.

Haze weather can also lead to nearly formation ultraviolet ray is abate, infectious germs. Due to the lack, children lack of ultraviolet irradiation, vitamin D production, for the absorption of calcium, cause rickets in infants, growth slows down. Will directly affect peoples mental health, mental laziness, depressed, etc. No wonder these days the mood will be so happy.

Point of view, to eliminate the fog, we should reduce waste emissions; Reduce the dust; Especially to do less drive a car, use public transit. In order to better tomorrow, lets start environmental action today, the blue sky, green water, green and quiet we need to create your own!

最近几天，天空都是阴沉沉地，看不到太阳，给人一种冷飕飕的感觉。你看：近处，半山电厂的两个冷却塔，若隐若现;远处的半山，没了踪影。还整天让人精神懒散、心情低落。报纸、电视都在宣传：近期雾霾严重，要尽量减少外出、少开窗户。可见雾霾严重污染空气，使空气质量下降，影响人体健康。我很想了解雾霾对人的危害，于是上网去查了一下，真是“不看不知道，一看吓一跳啊!”

雾霾有数百种大气化学颗粒物质组成。其中就包含：有机溶胶粒子、燃料和汽车废气等。它可以直接进入并粘附在人体呼吸道和肺泡中，引起急性鼻炎和急性支气管炎。对于阻塞性肺气肿、支气管哮喘等患者，雾霾天气会使病情急性发作。如果长期处于这种环境，还会诱发癌。

它对心血管系统有影响。雾霾天气中污染物多，气压低，容易引起心血管系统的急性发作。比如雾大的时候，水汽含量高，如果人们在户外运动的话，会造成胸闷，血压升高等症状。

雾霾天气还会导致近地层紫外线减弱，传染性病菌滋生。由于日照减少，儿童紫外线照射不足，体内维生素D生成不足，对钙的吸收减少，引起婴儿佝偻病，生长减慢。还会直接影响到人们的心理健康，让人精神懒散、情绪低落等。难怪这几天心情会这么不舒畅。

看来，要消除雾霾，我们要减少废弃物的排放;减少扬尘的行动;尤其要做到少开汽车，多用公交出行的方式。为了更好的明天，让我们今天就开始环保行动吧，蓝天、碧水、绿色、清静需要我们自己创造的!

The air we breathe is so freely available that we take it for granted. Yet without it we could not survive more than a few minutes. For the most part, the same air is available to everyone, and everyone needs it. Some people use the air to sustain them while they sit around and feel sorry for themselves. Others breathe in the air and use the energy it provides to make a magnificent life for themselves.

Opportunity is the same way. It is everywhere. Opportunity is so freely available that we take it for granted. Yet opportunity alone is not enough to create success. Opportunity must be seized and acted upon in order to have value. So many people are so anxious to "get in" on a "ground floor opportunity", as if the opportunity will do all the work. Thats impossible.

Just as you need air to breathe, you need opportunity to succeed. It takes more than just breathing in the fresh air of opportunity, however. You must make use of that opportunity. Thats not up to the opportunity. Thats up to you. It doesnt matter what "floor" the opportunity is on. What matters is what you do with it.

noticed and are easy to do the criminal things. We need to learn to protect

ourselves, life is precious.

Our house is on the main street of the village so I always saw a lot of people on the streets There were farmers, fishermen, and a few merchants in the village.

Also, we enjoyed running on the beach chasing each other. On breezy days we used to enjoy flying kites on the beach. When I look back on my early life in the village, I feel I had a happy childhood.

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。

Australia is one of the famous Oceanian country. The country is famous for its wool production and seashore tour. As the climate there is warm and comfortable, many people spend vocations there every year. I’m a super fan of water entertainment, so I choose it as my destination.

In Australia, the sky is bluer than blue, the clouds are whiter than white, all the local people enjoy an optimistic and active life. They also show their kindness and enthusiasm to the tourists.

The first step should be Sydney Opera which is among the most brilliant and splendid architectures in the world. Many world-class plays are put on in it .The surface and shape of it is like a seashell with glory decorations inside.

Then Melbourne is a good choice to be as the next step. In Melbourne, skin screen is a must to take with as the sunshine is upset and may burn your skin. The most attractive thing to me is the Australia Open, which is one of the biggest world-class tennis competition. Many great players such as Roddick Federer and its local player Hewitt etc. gather to compete. It’s really a feast for the eyes.

Australia is also home to one of the most challenging and exciting surfing and diving projects. As we know, it is always called “a country riding on the back of sheep”. From the interesting saying ,we can know something about the rich wool-production country. If you love animals, kangaroos and kaolas are good company to you .

So don’t forget Australia when you plan a trip.

During the 15 days from New Years Eve to Lantern Festival, Beijing was affected by smog for more than half the time, because of which people suffered a lot. On the road people drove slowly because they could not see clearly. People also suffered from many illnesses caused by smog.

The smog in Beijing has been caused by many factors, in which the increase of cars in the city area plays an important role. The cars send off a lot of poisonous gases, which in turn adds to the already serious air pollution.

In my opinion, the number of cars should be limited. We should call on the people to use more public transport. Only in this way can we expect to have more sunny days.

在新年除夕到元宵节的15天里，北京受到烟雾的影响超过一半，因为人们遭受了很多痛苦。路上人们开车缓慢，因为他们看不清楚。人们也遭受了许多由烟雾引起的疾病。

北京的烟雾是由多种因素引起的，其中城市汽车的增长起着重要的作用。汽车排出大量有毒气体，这反过来又加重了业已严重的空气污染。

在我看来，汽车的数量应该是有限的。我们应该号召人们使用更多的公共交通工具。只有这样，我们才能有更多的晴天。
