高二年级英语作文（汇编20篇）

I always feel tired after eight classes a day, so my dream school starts at 8:30 a.m. and ends at 3:30 p.m. There are three lessons in the morning and two in the afternoon. We can choose our favorite lessons to learn. We can spend more time doing some outside reading. The students do after-school activities for one and a half hours every day. We needn’t do a lot of homework. We are all happy to stay at school.

Besides that, my dream school looks like a big garden. There are many kinds of flowers around the modern buildings. Sweet perfumes are diffused all around. If I want to have a rest, I can lie on the grass, listen to music by the lake or look out at the flowers from the classroom windows.

The teachers here are kind and helpful. They are not only our teachers but also our good friends. The students are polite and friendly. We all know how to keep our school clean and tidy. There is no litter around the campus.

I love my dream school. We will grow up to be happier there.

I love my father but not his job!

转眼间，牛年已经来了。而牛年也是我的本命年。也就是说，我十二岁了。 In a blink of an eye, the year of the cattle has come.And Niu Nian is also my life year.In other words, I am twelve years old.

看着一去不复返的时光，我感触良多。在过去的十二年里，我最感谢的是爸爸妈妈。是他们给了我一个温馨的家，养育着我，我无声无息地长大，不知不觉中，他们额角上已经出现了白色的鬓发，皱纹是岁月留给他们的痕迹。在这十二年里，他们毫不抱怨，对我的爱始终如一。

中国有句老话，叫做“可怜天下父母心”，说的就是这些虽然默默无闻，但却十分伟大的父母吧。记得那次我出去玩，天黑了还没有回家，爸爸妈妈急得像是热锅上的蚂蚁一般，直到我回来，他们还仿佛没回过神来一般，紧紧抓住我的手，久久不曾松开。小时候的我，经常生病。我生病时，妈妈就整夜整夜地不睡觉。端来一盆热水，为我擦头，擦脚。每当我提出什么正当的要求时，她都会尽量满足我，还每个月至少给我买一次书。

我最敬佩的人是老师。是老师传授给了我知识。老师们兢兢业业、任劳任怨，好像要把自己胸中所学都交给学生一般。为了我们这些调皮的学生，他们累得腰酸背痛，却忍着痛给我们上课。每次我们犯错的时候，他们总是谆谆善诱。当我们执迷不悟的时候，他们总是象征性地打我们几下，其实，打在我们身上，痛在他们心里呀!在他们眼里，我们就是一群永远长不大的孩子。一次我没考好，老师就给妈妈打了一个电话，谈了很长时间。这次，我们班本来应该数学考140分以上的同学(包括我)都没考上，数学老师就把我们三个叫到了办公室，说责任就在你们三个身上。还用殷切的目光看着我们。

我最喜欢的东西，那莫过于书了。在十二年里，他陪我走过风风雨雨，对我不离不弃。在我失落时，是他鼓励我，在我伤心时，是他开导我。在我孤单时，是他陪伴我。书，是我的良师益友。现在，我书架上已经摆满了书，在书的帮助下，我逐渐变得沉稳、成熟。在成长的道路上，没有书这个朋友，确实不行!

对我的人就是姥姥、姥爷、爷爷、奶奶了。我一到姥姥家，姥爷就拉着我下象棋。虽然他知道我是一个臭棋篓子，但还是不厌其烦地跟我下棋。而姥姥就让我自己挑选自己喜欢吃的菜。每次到奶奶家时，奶奶都会做我吃的菜。每次，我感冒时，他们就会对我嘘寒问暖。我的健康就是给他们的礼物。

在经历了十二年的风雨之后，我十二岁了。在我的身边，还有许许多多支持我的人，帮助我的人，比如我我的朋友，他们为我“两肋插刀”。在这么多人的关心和帮助下，才有我的现在。在新的一年里，我一定不辜负那些帮助我，关心我，支持我的人们。我一定好好学习，天天向上，争取创造灿烂的明天，大家春节快乐。

There is only good mother, I was no exception. Mom has a white face, a pair of round eyes, a black head of hair. Mothers love is selfless dedication.

Mother every year in the winter are to weave a beautiful new sweater to me, let me have a warm winter. Mother to work every day, off work back to knit a sweater for me. You said: "what is this?" Is a mothers love.

When I was 4 years old a small lump grew on the arm, my mother took me to a hospital checking, the doctor said: "to do surgery." After much cogitation mom and dad agreed. Mother day and night after the operation finished watching I hardly slept a wink all night. You said: "what is this?" Is a mothers love. A mothers love reminds me of a mothers love poem "the wanderer". All the dribs and drabs, together, this is a mothers love.

世上只有妈妈好，我也不例外。妈妈有一张白白的脸，一双圆溜溜眼睛，一头乌黑的长发。妈妈的爱是无私奉献的。

妈妈每一年一到冬天都要给我织一件漂漂亮亮的新毛衣，让我过一个温暖的冬天。妈妈每天还要上班，下了班回来还要给我织毛衣。你们说：“这是什么”?是母爱。

在我4岁的时候手臂上长了一个小硬块，妈妈就带我去医院检查，医生说：“要做手术。”妈妈和爸爸经过再三考虑答应了。在手术做完之后妈妈一天一夜的守着我整夜没合眼。你们说：“这是什么?”是母爱。母爱让我想起了一首母爱的诗《游子吟》。所有的点点滴滴，汇聚起来，这就是母爱。

Dear Jim,

I’m so glad to hear your future education plan in Beijing in your last

letter. First I would like to express my warmest welcome to you and I am sure

you will have the most unforgettable experience during your college in

Beijing.

Learning your keen interest in Chinese culture, I suggest you apply for

Peking University, one of the best universities in China. Its Chinese Literature

major is perfect for you where you can be completely soaked in Chinese profound

history and rich culture. As for preparation, some reading in advance is needed

like The Story of the Stone while some online courses of spoken Chinese can be

helpful for you to adapt into the Chinese language environment.

I sincerely hope your dream will come true and it’s my pleasure to show you

around in Beijing when that day comes. If you have further questions, please

feel free to let me know.

Yours,

Li Hua

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.

Cell phones have become increasingly popular in china these days. wherever

you go you can see people using cell phones. many college students, even high

school students, have cell phones.

Cell phones have brought people a lot of benefits, but the most important

is that they are convenient. with cell phones in their hands, they can keep in

touch with anybody they want. if they want to get some information from the

internet, they can easily have their dream realized via cell phones too.

furthermore, if someone has a heart attack or a traffic accident, a call to

emergency hospital or to the police can quickly bring him the help he wants.

However, cell phones can also bring people problems. the most serious is

the electric wave radiation which is thought to be harmful to users brains.

another problem is that when people are having a meeting or having a class or at

a concert etc, the ring of the cell phone may interrupt others. so i think

people should use cellphones as little as possible and turn them off when they

are attending important meetings or attending classes.

To Remember Nanking Massacre

Early in the morning, when I searched the Internet, I found there were many news about the Nanking Massacre, our country’s flag had low down half, for the purpose of commemorating the people who were killed during that hard time. The massacre is such brutal, about 300 thousand people died, it is shame for our country, the Japanese who did the massacre deny their brutal act all the time. As the time went by, SomeJapanese want to clear his criminal with denying it, but we can’t forget the pain, we must remember it all the time, so that we learn the lesson and be strong. For those 300 thousand people, it will unrespect to them if they are forgotten, we must respect history, now we are still fight against the Japanese government.

一大早，当我上网的时候，我发现有很多关于南京大屠杀的新闻，我们的国旗降了一半，为了纪念在那个艰难时期被杀害的人。这场屠杀很残忍，大约30万人遇害，对于我们国家来说是多么耻辱啊，实行大屠杀的那些日本人一直以来都否认他们这么残忍的行为。随着时间的流逝，有些日本人想要通过否认来清除他们的罪行，但是我们无法忘记这样的痛，我们必须一直铭记，这样才学到教训，变得强大。对于30万人来说，忘记他们就是不尊重他们，我们必须尊重历史，如今我们仍然在和日本政府做斗争。

一个漫长的暑假已过去，迎来的是一个美好的秋天。新的一学期又开始了，迎着早晨的第一缕阳光，我们如同来到了一个崭新的校园，即将开始新的征途。

在上个学期的学习和生活中，也曾遇到过困难，也有开心，但这都已成为过去，我会把它当成我这个学期的学习动力，摆在我面前的一切都是新的，我理解到了，上学期的不足。在新的学期要如老师在评语中对我所说的要掌握好，好的学习方法和好的学习态度，我也明白了，由于现实的残酷，我们将不能在学习当中有一点点的马虎，因为上学期的数学给我带来了遗憾，我会抹掉胸口上的创伤，拿上我的武器，整装待发，新学期的目标早已在我脑海中彩排。

长远的目标是考上自己理想的大学，最近的目标是尽快跟上五年级的学习节奏，其实我的目标还有很多，也许不能一一实现，但我会尽自己最大能力去做。当然我明白这一路不会是一帆风顺，但它总会给我希望让我黯然欣喜的时候，踏踏实实地学习，认认真真地对待校规，班规，坚决不做有损学生身份的事。

我这个学期一定要努力，不要辜负了老师和父母对我的期望!!!

One Sunday afternoon when I was learning to ride my bike, I fell down and hurt my arms badly. As soon as my parents heard this, they took me to the hospital at once.

During my stay in bed, they took good care of me and cheered me up. Meanwhile, they helped me with my lessons. With their help, I caught up with my classmates. Now I’ll try my best to study well to repay my parents.

Many years ago, the movie about the youth became very popular, every year,

we can see many hot movies about the protagonist’s passed youth. People like to

recall their passed youth, which makes such movies sell good. But I find the

common things about these movies, all the protagonists’ youth are about

fighting, love and other negative things. I understand the directors’ intention,

they want to tell people youth is not perfect and having pities. Of course movie

is exaggerating, the real youth is about studying, at least, most people have

worked so hard to get into their ideal colleges. What the movies describe make

up some people’s youth, for which they don’t have the chance to experience. We

should not be misled by these movies, for the teenagers, their job is to study,

so that they can have a bright future.

There have been many environmental protection problems in recent years . One of the most serious problem is greenhouse gas emissions have caused climate change ,At the same time ,lots of trees have been used and wasted.So our earth is becoming warmer and warmer . .That brings us illnesses and death.

Luckily ，,many countries have done a lot to stop environmental pollution。Its the most important in the environmental protection today.

In my opinion ,on the one hand ,through education we should make people realize that destroying the environment means destroying ourselves,..On the other hand ,we should try to do something to produce fewer greenhouse gas emissions.

In a word .we must develop low-carbon economy

现在这些年已经有很多关于保护环境的问题。其中最严重的一个问题就是温室气体排放已经造成了气候改变。同时，很多树木被砍伐掉了，而且大量别的资源已经被用完或者浪费。所以我们的地球变得越来越温暖(热)。这样带给我们的是疾病和死亡。。

幸运的是，很多国家已经采取了很多措施来控制环境污染问题。如今，这是最重要保护环境的措施。

我认为，一方面，虽然教育我们应该让人们意识到破坏环境就是伤害人类自己。另一方面，我们应该尽力做一些事情来控制温室气体增长。

总之，我们必须发展低碳经济。

Knowledge can be acquired from many sources. These include books, teachers and practical experience, and each has its own advantages. The knowledge we gain from books and formal education enables us to learn about things that we have no opportunity to experience in daily life. We can study all the places in the world and learn from people we will never meet in our lifetime, just by reading about them in books. We can also develop our analytical skills and learn how to view and interpret the world around us in different ways. Furthermore, we can learn from the past by reading books. In this way, we won’t repeat the mistakes of others and can build on their achievements.

获得知识的来源有很多。这些包括书籍，教师和实践经验，每个人都有自己的优点。知识从书本上及正规教育使我们知道在日常生活中没有机会经历的事情。我们可以研究世界各地的人学习我们不会在我们的有生之年遇见，只在书上读到的人。我们也可以培养分析的技巧，并学习如何看待和理解我们周围的世界以不同的方式。此外，我们可以从过去中学习，通过阅读书籍。这样，我们就不会再重复别人的错误，并且能够以他人的成就。

Practical experience, on the other hand, can give us more useful knowledge. It is said that one learns best by doing, and I believe that this is true, whether one is successful or not. In fact, I think making mistakes is the best way to learn. Moreover, if one wants to make new advances, it is necessary to act. Innovations do not come about through reading but through experimentation. Finally, one can apply the skills and insights gained through the study of books to practical experience, making an already meaningful experience more meaningful. However, unless it is applied to real experiences, book knowledge remains theoretical and, in the end, is useless. That is why I believe that knowledge gained from practical experience is more important than that acquired from books.

实践经验，另一方面，可以给我们更多有用的知识。这是说从做中学的效果最好，我相信这是真的，无论一个人成功与否。事实上，我认为犯错是最好的学习方式。此外，如果想要有新的进展，这是必要的行动。创新不能只靠阅读是实验。最后，我们可以将所获得的技巧和见解通过书籍来实践经验的研究，使得原本有意义的经验变得更有意义。然而，除非它应用于实际经验，书本知识是理论和，最后，是无用的。那就是为什么我会认为从实际经验中获得的知识比从书本中学到的更重要。

Nowadays, we can often hear the discussion whether buying cars should be encouraged. Some people suggest that we should buy cars. But others claim that driving cars is not a wise idea. As far as I am concerned, I am in favor of the latter opinion.

To begin with, there are few parking lots, so the streets are made narrower by the cars parked along the roads. For example, my father could not find any places to park when we went to the supermarket.

Moreover, many drivers do not obey regulations, because people do not pay enough attention to the rule of traffic. For instance, I often see people cross the road when the traffic lights are still red.

Last but not least, the growth of new roads’ construction is usually slower than the increasing number of cars. For example, the length of the road has gone up by 20% in 2002. However, the number of cars increased by 50% in the meantime.

From what has been discussed above, we could draw a conclusion that encouraging buying cars is not fit for today.

My mother is a great woman, she does all the house work, now I have grown up, so I want to help her with her work.

I will wash the dishes after the meal and I wash my own clothes.

My mother is so happy to see me doing this, she tells her friend that how good I am.

I am happy I can help my mom, I want to do better in the future.

我的妈妈是一个伟大的女人，她做完了所有的家务活，如今我已经长大了，所以我想要帮助她做家务。

我会在饭后洗碗，自己洗自己的衣服。

我的妈妈很高兴看到我做这些，她告诉她的朋友我有多么好。

我很高兴可以帮助妈妈，将来我想要做得更好。

Today, more and more young people are crazy about western festivals. When western festivals come, they usually go to restaurants or shopping malls to have fun.

如今，越来越多的年轻人都对西方的节日着迷。当西方节日到来的时候，他们常常去餐厅或是商场娱乐。

Why do the young enjoy western festivals so much? Since they worship everything new, and they can’t resist the temptation. In their opinions, western festivals symbolize the fashion, while our Chinese traditional festivals are out of date. No wonder we always feel so boring during our traditional holidays. If we still turn a blind eye to our traditional festivals, our culture and civilization will disappear someday. Accordingly, it is high time for us to pay close attention to our Chinese festivals.

为什么年轻人这么喜爱西方节日呢?大抵是因为他们喜爱新鲜事物，抗拒不了诱惑。在他们看来，西方节日代表着时尚，而中国传统节日则太土了。这也难怪我们也觉得我们的传统节日太过无聊了。如果我们对传统节日漠然置之，那么某天我们的文化文明终会消失。因此，我们该多多关注我们中国自己的节日了。

As a Chinese, we have the obligation to protect our culture and custom. So I think we should celebrate our Chinese festivals by doing some traditional activities. As for western festivals, we needn’t to be too excited about them. We can just send our best wishes to our best friends during those festivals.

作为一名中国人，我们有责任保护自己的文化习俗。所以我认为应当在庆祝中国传统节日时候举办一些传统活动。而对于西方节日，我们不需要太过激动。在这些节日里我们应该只需简单的送上祝福就好。

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!

It is the traditional merit to respect the old in China. Since I was very

small, I received the education that young people should respect the old without

any question. I kept it in my heart and showed respect to the old people all the

time. But as I grew up and with the development of Internet, media exposed the

negative side of the old people. They were rude and impolite sometimes, some of

them took it for granted that young people should serve to them. So people start

to think about whether it was worthy giving priority to the old. In my opinion,

it is the adorable behavior that deserves to be respected, instead of the age.

When old people were rude, they also needed to face the publics criticism. Only

the multi-respect can help people better communicate.

Modern American famous entrepreneurs iacocca said: "without innovation, death." Is ah, this sentence is absolute. Innovation to the development of a person indeed played a very big effect, only learn to innovate, to learn from various angles, to make themselves permanently in the invincible position, to make it and get play on their original level, thus more effectively to change yourself. Rut is one of our well known idioms, which contains the truth is told us to learn to innovate. Once upon a time there were two men, a love to imitate celebrity calligraphy, and the other one is required to follow their own style to practice, another ultimately become a famous calligrapher, but the rut is still unknown. Thus, dares to innovate, to do something.

And what was said Mr Qi baishi is the portrayal of the story: "like I am dead, I dead." Go out of our predecessors framework, will not have their own heaven and earth. There is a story about a businessman and with partners go to gold, because gold prospectors, where resources are less, he learned to innovative ideas, to sell water, adapt to the needs of the market, and made a lot of money. These two examples all tell us the importance of innovation. Now the social everyone on the premise of innovation and to development, improvement, and change. How about, a person that has special mind, has innovation consciousness and the spirit of perseverance, he will be how the end of what? Of course is a perfect ending!

So, let us act, the academic society innovation, advocating innovation, to constantly improve themselves, while we its spring time, trying to do, is a person get give full play to the original level, make oneself permanently in the invincible position, let oneself have a perfect ending, for their own life added a brilliant color! Friend, remember: innovation of self-improvement. Try to do it!

现代美国著名企业家艾柯卡说过:“不创新，就死亡。”是呀，这句话非常有绝对性。创新对一个人的发展的确起了很大的效果，只有学会创新，学会从多个角度，才能使自己永久地处于不败之地，使之并在自己原有水准上得到发挥，从而更高效地改变自我 。 墨守成规是我们众所皆知的一个成语，其中包含的道理就是告诉我们要学会创新。从前有俩个人，一个酷爱模仿名人书法，而另一个人则要求遵循自己的风格去练习，最终另一个成为一名著名的书法家，而那个墨守成规的人仍默默无闻。由此可见，敢于创新，才能有所作为。

而齐白石先生所说过的话正是这个故事的写照：“似我者死，学我者死。”走不出前人的框架，自己就不会有自己的天地。 还有一个故事讲述的是一个商人与同伙伴各自去淘金，由于淘金者数不胜数，哪儿资源又少，他学会创新思路，从而改卖水，适应了市场的需要，从而赚了许多钱。 这两个事例无一不告诉我们创新的重要性。如今，这个社会大家都以创新为前提，去不断发展，完善，改变。试问一下，一个人即拥有非凡头脑，又有创新意识和坚持不懈的精神，他会又怎什么样的结局呢?当然则是完美的结局咯!

所以，让我们行动起来，学会创新，提倡创新，去不断改善自我，趁我们其春年华，努力去做，是个人原有水准得到充分发挥，使自己永久性地处于不败之地，让自己拥有一个完美的结局，为自己的人生添上一笔绚丽的色彩!朋友，记住：创新改善自我。努力做吧!

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。
