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。

【提要】本篇《小学3年级上册语文第5单元作文：广州的春节》由小编特别为需要春节小学作文的朋友收集整理的，仅供参考。内容如下：

想起宋代王安石写的《元日》这首诗“爆竹声中一岁除，春风送暖入屠苏”我们广州也不列外，热闹非凡。

廿八时，大家会有一次大扫除，会把家里整理的像新的一样，该扔的扔掉，洗凳子，把每一个死角洗得干干净净，家里不会有一点灰尘。然后在打扮的很有年味，这时，家家户户都会炸油角、煎堆、蛋散等，每逢春节，整条巷子都会飘出一股油炸香味，这香味让你口水都忍不住留下来，这让我感觉，年味来了。

之后，我们广州人会有个习惯，就是去花街逛逛，人们在马路两旁搭架做花档，那天，人山人海，中间行人。夜市灯光明亮，如同白昼。花市高峰时人如潮涌，摩肩接踵，花市里红紫纷华，使人眼花缭乱。由于人潮拥挤，买了花枝花束，都要高高举起，否则就要给人挤落，空剩残枝。其次，金桔树是广州人必买的一样东西，在花市里，你也会看到成多的金桔树摆在那儿。回家后是吧他摆在家门口，挂上几分利是，代表大吉大利。

除夕早上，人们会把家里对联换新的，吃油炸角，马蹄糕等在除夕夜，人们都会有熬到12点，在这段时间，一家人围在电视前看春节联欢晚会，12点钟声一响起，鞭炮声变络绎不绝。

初一一大早，我们起床穿上新衣服，然后会对拜，遇到长辈随口说声：“新年好，恭喜发财。”俗谚说：“有心拜年初一、二，无心拜年初三、四。”说的是拜年越早越见其诚意。故此，有的人起床后就立刻向亲戚朋友拜年去了，回来后才吃饭。拜年是，还会带上几分礼物，大桔是不可少的，大桔谐音“大吉”，带多少都行，但是不能奇（ji）数。

初二，回娘家。就是自己的妈妈带着我们去外公外婆家拜年，带上礼物。

初三、初四便可以待在家里，或者去哪里玩。

到了元宵节，有是一个热闹的节日，这是春节的最后一天，人们晚上一家人围在一起吃汤圆，看烟花……过了这一天，大人们该上班的上班，小孩们该上学的上学，春节就结束了。

广州虽然是个现代化的城市，但还是以传统方式过年。

Chang Yuxian is my best friend.I think hes a handsome boy.He came to our school half a year ago.Hes very shy in class, but not a stupid boy.常予先是我最好的朋友。我觉得他是个帅气的男孩。他来到我们学校已经有半年了。他在课堂上很害羞，但他决不是个愚蠢的孩子。

Every time when the teachers ask us some questions, he doesnt often put up his hand.He lowers his head in order not to meet the teachers eyes,because hes afraid and shy.But he knows every answers.每次当老师提问的时候，他经常不举手。他把头低下为了不跟老师目光相遇，因为他害怕、害羞。但是他知道每一个问题的答案。

Little by little, he begins to answer the questions in class, and takes part in the activities with us.He wants to challenge himself.If you are as shy as him, please follow him.Teachers are not tigers, but they are our best friends in school.渐渐地，他开始在课堂上回答问题了，而且还积极参加同学们的集体活动。他想要自我挑战。如果你跟他一样害羞，就像他那样做吧。老师不是老虎，而是我们在学校最好的朋友。

Lets be brave. Dont be shy any more!让我们勇敢起来，不在害羞!

The night before Christmas, people are bringing a sleeping quietly under the moonlight, the earth, on a quiet, they are waiting, waiting for the arrival of the new year.

See, thats who, a boy. He quietly sat in the window, watching the moon, seemed to be waiting for someone, but he was waiting for whom? Now, who else would come? I was somewhat puzzled by his behavior. But he is still sitting in the window waiting for, but sometimes look back at the clock

Chusok ("fall evening") is a Korean "Harvest Moon" (Han-gawi) festival set

on the 15th day of the eighth lunar moon. Chusok (韩国中秋节)， also known as the

Korean Thanksgiving or Mid-Autumn Festival， is one of the most celebrated Korean

holidays. It occurs during the harvest season. Thus， Korean families take this

time to thank their ancestors for providing them with rice and fruits.

The celebration starts on the night before Chusok and ends on the day after

the holiday. Thus， many Korean families take three days off from work to get

together with family and friends.

The celebration starts with a family get-together at which rice cakes

called "Songphyun" (蒸糕) are served. These special rice cakes are made of rice，

beans， sesame seeds， and chestnuts. Then the family pays respect to ancestors by

visiting their tombs and offering them rice and fruits. The Koreans visit the

graves of their ancestors to bow and clean the area for the coming winter. In

the evening， children wear their favorite hanbok (traditional Korean clothing)

and dance under the bright moon in a large circle. They play games and sing

songs. Like the American Thanksgiving， Chusok is the time to celebrate the

family and give thanks for their blessings.

Community activities include masked dance， Kanggangsuwollae， an ancient

circle dance， tug-of-wars and the tortoise game， kobuk-nori (乌龟游戏)， in which two

men dress as a tortoise and tour the village dancing and performing for food and

drink. Most of all， Chusok is a time to give thanks for the autumn harvest and

reaffirm familial and community ties.

There are four seasons in the year. They’re spring, summer, autumn and

winter.

Spring is warm and sunny. In spring days, everything in our nature is

green, so we can go out to release ourselves and breathe the fresh air. I think

its a good way to enjoy our beautiful nature.

Summer is hot and rainy, but summer is the best season for entertainment,

because we can go swimming in the sea and enjoy the beautiful sunshine on the

beach. It must be very interesting.

Autumn is very cool and comfortable, and it is also the best season for

harvest. In autumn days, the farmers are busy in their fields. If we had a

chance, we could go to the countryside and pick up some fresh fruits and

vegetables.

Winter is very cold and freezing. In winter, our world is covered with

white snow, so we can either make snowmen or fight with snow. And we can also

enjoy the beautiful ice lanterns in Harbin. But I prefer to go to Sanya during

that time. As its on Hainan Island, the weather is always so temperate. Even in

December, I can still enjoy the green palm trees, the beautiful sea, the sunny

beach and the blue sky. Maybe I can find endless pleasure there.

Internet is now coming into our life. It brings us not only a lot of convenience ，happiness but also troubles. Some students use Internet as a too to study. They look up the meanings of the words， a translated form of a sentence，the background of an event or a story ，the information of a company or a famous person，etc.

They also read news or send e-mails through it. Internet helps them learn more and study well.

On the other hand，some students play games，chat with friends ，see the pictures or films even the unhealthy ones on the Internet the whole day. They are not interested in their subjects. It’s very dangerous for them!

The Internet’s advantages and disadvantages are shown clearly to us. I think we should make good use of it and stay away from the unhealthy websites.

Summer vacation has arrived, and it is a happy holiday, but do you have a

plan for your summer vacation? Although the summer vacation can relax, but you

cant put myself too loose, but to continue to work hard for next semester!.

What can we do for ourselves during the summer vacation? There are lots and

lots. Much like stars countless, for example: in the summer school program

enrollment, swimming lessons, and family to go out to play with my classmates,

riding a bicycle to go for a ride...... Etc..

In the summer school program can add new knowledge, can also review the way

before the content of homework; swimming can enhance their ability of self-help,

also can cultivate interest, so he will not feel bored; and the family out can

choose to visit the places of historic interest and scenic beauty but also to

the scenic area, to enjoy the wonders of nature, which not only can to broaden

their horizons, also can make their own eye-opening; with the students about

riding together together, talk together, let oneself not sitting at home playing

computer, addicted to electronic games, can also make their own troubles to the

winds!

If I had words, I would have chosen to go all the way, because I thought it

was very meaningful and liked, and it would not be annoying.

Environmental problems are as big as not for individual country or individual people to address. In other word, we have reached the stage that environmental problems be solved for international view. To what extent do you agree or disagree?

In recent years, many nations have become more aware of the environmental issues each nation faces, such as air and water pollution. The question is, are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of becoming an international problem needing international cooperation to resolve.

Because of the differences in environmental policies, resources and technology, international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology. By pooling international resources and technology to address the environmental problems, the disadvantaged nations are provided the assistance needed. Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole.

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection. In order for international cooperation to occur and succeed, the nations of the world must submit themselved to international standards and supervision by an international commission elected by the participating nations of the world. All members must agree to abide by the standards established.

The environmental issues facing each country are not unrelated to the well being of the rest of the world. The impact is long term and international in scope. Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole, depletion of the ozone layer, water pollution, air polution, etc., the environmental conditions of the world will deteriorate to the detriment of every nation, not just those that ignore or lack the resources and technology to resolve their individual environmental problems.

As part of the same planet, it is the responsibility of each individual and nation to protect the global environment. Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment.

This afternoon, my parents and I went to Huad Shan with their friends.Recently, they have developed a new feature such as Gu Keng coffee, yard coffee shop, and B&B.This time, we went to a place that has natural trees, flowers around us. On the side of the stone road, had a long river and we could hear the water voice. It was very comfortable. The most I like it because there were not many people so that we could have a quiet condition.In addition, adults took noodles, fruits, and teas to get more interest. People in there were so friendly; they could lend us the desk, the chair, and everything we need.Now, Huad Shan is not only a place for hiking but also a tourism scenic spot. We can go there with our family or friends on holiday. It is certainly can relax ourselves.There are full of busy and nervous feeling in our usual life. So we took advantage of free time to go for relax. It is really a big enjoyment

Study has been an important part of our life. I study hard in school and

even I graduate, I still keep reading books. Reading books not only brings me

the knowledge, but also happiness. The knowledge I learn will be the greatest

treasure of my life.

The basic things I learn from books teach me the way to see the world. When

I was very small, I fell in love with reading. I read cartoon books, then I

learn more about the world. For example, I know more about sports and the

different culture of areas. So I know the diversity of the world. When I have

conflict with others, I try to understand them instead of arguing with them.

The books show me the way to solve problems. I read about many inspiring

stories about how great people get success. So when I meet difficulties, I tell

myself not to give up, failure is the mother of success. So I can get over the

difficulties and become stronger.

Study has been the long-life career for me and I enjoy the wisdom I

get.

Travelis a very good means of broadening a persons perspective. It makes you come into contact with different cultures, meet people of different colors and go through peculiar rites and ceremonies. Travelling much, you will not only enrich your knowledge and experiences, but also be aware of the vastness of nature.

Travel may also relieve person of boredom and gloom. Travel brings you enjoyment and attraction. It gives you a pleasant experience, which will disperse your boredom and make you forget whatever annoys you. Travel broadens your mind and leaves you good memories. Later, you may go over these memories and enjoy your past experiences, thus keeping a fresh and sunny mind.

The fields his study, nature was his book.

Travelers can choose different modes of transportation which have advantages and disadvantages. Airplanes are the fastest but also the most expensive. Buses and trains are less expensive, but they soon make you feel cramped and uncomfortable. Ships provide you with comfort unless you get seasick. Most people can afford traveling by bicycle, which, although slow, can limber up your muscles and get you closer to nature.
