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。

There is only one word which can describe my childhood. The word is“carefree”that so many todays kids do not understand， although they have delicious food， beautiful clothes and pretty toys.

My parents never forced me to do anything. I recited a lot of poems and fine articles， but not for performing before their friends and our relatives， just because I enjoyed rhythms and words. So I never considered them a burden。 Later， when I was in the primary school， the homework was very few and easy to do， and I was never asked to be the top students.

Nor did my parents stop me from doing anything. After I finished my homework， I could stay outside for a whole afternoon to do whatever I liked. I used to go swimming in the river in summer， skating on the ice in winter. Sometimes I played basketball or football with my little friends. I could read any book， and my parents never examine it before my reading.

Sometimes I think my childhood was boring and not unforgettable， but I was really carefree and happy then. What is more important than to give a child a happy childhood?

只有一个词可以描述我的童年。这个词是“无忧无虑”,很多今天的孩子不懂,尽管他们有美味的食物,漂亮的衣服和漂亮的玩具。

我父母从不强迫我做任何事。我背诵很多诗,好文章,但不执行他们的朋友和亲戚之前,仅仅因为我喜欢节奏和单词。所以我从不认为他们是负担。后来,当我还在小学,作业很少,很容易做,而且我从未要求最优秀的学生。

我的父母也没有阻止我做任何事。我完成了我的作业后,我可以呆在外面整整一个下午做任何我喜欢的。我过去在河里去游泳在夏天,在冬天在冰上滑冰。有时我和我的朋友打篮球或足球。我可以读任何书,和我的父母从来没有检查过我的阅读。

有时我觉得我的童年是无聊和不难忘,但我当时真的无忧无虑的快乐。什么是更重要的不是给孩子一个快乐的童年吗?

Everyone always has a good Sunday.

On Sundays, everybody does some things what he like.

Last Sunday, Jack had a relaxing Sunday.

He got up 6 o’clock.

After breakfast, Jack played basketball with his friends.

They were very happy.

Then he played the guitar in the room.

And he sang songs very loudly.

Though it’s very relaxing for him, it also make very noisy for neighbors.

Maybe he should turn down the music.

At noon, jack fed his pet cat henry.

He is Jack’s favorite.

Jack always play with him on the weekends.

At night, he watched TV on the sofa.

At the some time, he ate many delicious snacks.

So he really had a great time.

At the of day, jack thought if I always have a relaxing Sunday like today.

I will become the happiest boy all over the world.

It is a celebrating day. I got in touch with Michael whom I have been losing contact for one year.

It is really magic. I was searching online aimlessly yesterday when an idea struck me suddenly: since Ben can find out my secret by keying in my name in the search engines, why can’t I do so, either?

I intended to find out something about Ben in revenge in the first place, but soon extend my name list to a wider category. It was then that I recalled Michael suddenly.

We have lost contact since our last correspondence in my senior 3. He mentioned to me in his last letter that he was preparing for going to UK to further his education. I, shamefully, was too busy to reply his mail then. When I was recommended to ZJU and won the final freedom, I thought he had already been in UK so I had no idea where to write him.

I used to think that we would never meet again. However, when I browsed the entries about him, I found out excitedly that he is still in P.R.C.!!

Without a moment hesitation, I ran upstairs to my dorm and found out my old address book. Thank goodness, his home no was still there.

After 3 times calling with no answer replies, I eventually got him on the phone. He was more surprised than I could imagine that when I asked for his hp no he was too nervous to remember it. :P Hehe.

Life is enjoyable in moments such like this. Old friends meet again surprisingly, on a road of their own ways to their dreams. they look at the face of each other, and recognize the old pal. It is such moment that makes me feel grateful to life: whenever I set off for a new destination, I see I have friends in the same direction, with whom I won’t feel alone any more.

In China, students work so hard, they study day and night, for the purpose of getting the high mark, so that they can go to a better school, which will bring them more promising future. To get the study time as more as possible, some students move their books to the study room, they want to occupy the seat, so they put a lot of books as the sign that the seat has been taken by someone, other people can’t take this seat. In my opinion, studying hard is a good thing, working hard will lead people to success, while taking the seat for a long time is not a civilized behavior. It is a kind of wasting resource, when students are not here, but the seats are empty, they should be left for other students to study.

在中国，学生很努力学习，他们白天和晚上都在学习，只为了得到更高的分数，这样他们就可以进入到更好地学校，能给他们带来更加光明的前途。为了尽可能地更多时间学习，一些学生把他们的书本搬到了自习室，他们想要占位置，所以他们放了很多书，作为位置已被人占有的象征，别人不能做这个位置。在我看来，努力学习是一件好事，努力工作能让人们成功，但是长时间的占据位置不是文明的行为。这有点浪费资源，当学生不在学习时候，位置也是空的，他们应该把位置让给别的学生来学习。

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。

Today is the National Day holiday for the fourth day, time can be really

fast. My mother took me to my grandmothers home for the first two days, and the

home of my grandmother was really busy. A lot of Grandpa and grandma, aunt,

uncle and brother, sisters, I almost fainted, that is to recognize the halo, ha

ha ha ha. My mother told me that I was the fifth generation. This is called the

fifth world. Each holiday to see grandma, Grandpa too too, they are wearing

special festive costume, really good-looking.

The morning I was at home to review the homework, mother was glad to praise

my mamas boy. So in the afternoon to take me to the Tang Dynasty city people

here to play, really much ah! The atmosphere of a festival on the square is

happy. The development of the game we went to the west city play scouts, there

are a lot of kids, because I was the first time to play, so start from the

simple to play for a while, I was familiar with the essentials, but also know a

lot of new friends. Mom said this is the fun of games. In the process, you will

make up for the shortage, accept good suggestions, and recognize new friends.

Its important to exercise our willpower. Only by persisting efforts can we get

to the end. Next time I will come here. I want to play the game that is more

difficult. I believe I can go smoothly. I cheer for myself: Liu Zhuoya, you are

the best.

I had a good day today, and I hope it can be like this every day.

Every body wants to succeed. But when it comes to the question that which

factor leads to success, opportunity or hard-work, different people will offer

different answers.

Some people think that opportunity is the first factor leading to success.

They hold the idea, as a proverb saying, “Man proposes, god disposes”. Because

almost all successful people have good luck and have caught their valuable

opportunities, they believe that opportunity is a leading condition of the

success. If seizes and makes the best use of opportunity available, one can

succeed surely. In summary, to them, chances and lucks play the most important

role on the road to success.

However, others maintain that “no pains, no gains” .Without exerting

oneself, one could never expect to achieve success in no matter what one is

doing. As is known to all, there is no royal road to the summit of success. One

is likely to succeed only when one has worked with whole-hearted devotion and

perseverance. Those who are lazy, sloppy and indifferent to their work, those

who never concentrate on work will definitely end in failure. On the whole, as

far as they are concerned, hard-working is the decisive factor to success.

In my view, both hard work and opportunity eventually matters. They are

inseparable from each other, and put together, they make a great success. Hard

work is to luck what fish is to water, and can be seen as an interior

precondition of success. It lays the corner-stone for building a house while

luck serves to cement it, to make the building bricks adherent to one another.

They are the twins that contribute to success together. They are the factors

from within and without respectively. We must work hard, make efforts and get

prepared. When opportunities come, meet and make full use of them. Only in this

way can we succeed one day.

All the people often say:"mothers love is the greatestin the world!"Yes,mothers love is very great.We mother give us very too much love.But a big number of us. dont know our mother give us too much love.Mothers are very tired .We dont know make her to rest.Mothers are thirsty.We dont know give they a cup of tea.When we beacome to father or mother.We know our parents give us much love .So,at this moment.We mut reture a good grades to our parents.

Most people in China like playing sports, because it’s a good way to keep

healthy.

In big cities, people play many kinds of sports. The old people always get

up early to play Talchi or go for a walk. The middle-aged people often dance

together in squares in the evening, which has become a tradition. While the

young like going swimming in summer and go skating in winter.

What’s more, there are some other popular sports in China, such as table

tennis, football, basketball, volleyball, badminton and so on..What is your

favorite sport? Can you tell me?

Dear Mary, Pressure is a serious problem in today’s world. I know you are under too much pressure. You can’t get on well with your classmates; you may worry about your exams. I’m always under pressure, too. My parents want me to be the top student in class. So they send me to all kinds of training classes at weekends.

Last Monday evening, I had a talk with my mother. I told her I was not lazy. I really felt tired. I needed time to relax. My mother agreed with me at last. So I think a conversation with your parents is necessary to solve the problem. Less pressure, better life! Best wishes to you! Your, Jane

上个星期一晚上，我和我的妈妈说了一次。我告诉她我不懒。我真的感到很累。我需要时间放松。我妈妈终于同意了。所以我想和你父母的谈话是解决问题的必要的。更少的压力，更好的生活！最美好的祝愿给你！

Everyone may have his own dream. Someone may want to be rich, someone may

want to be beautiful, and someone may want to have power. But Im different from

them. My dream is special. I want to have a pair of wings. Because I want to fly

in the sky，I like the feeling of freedom.

If I have a pair of wings，Im sure it will be very wonderful. I can fly

below the blue sky with the birds. I can enjoy the music of birds. I can fly

across the cloud and the small wind will blow past my face. The feeling must be

the same as that my mother caresses me.

I can fly over the sea, below the rainbow, through the forest I can see all

the wonderful view. But I know that it will never be uteri have another instead.

I want to have a fly of my own. The plane must be very small and light. It has

to carry only one person. It can fly by wind or sunshine. It can fly for a very

long time. And the important thing is that it must be very save.

As the proverb goes, “no one knows the value of health until he loses it.”

From this, we know that health is very important to everybody. But how to keep

fit? Many people believe that sports can offer people health and pleasure. As

far as I concern, I think doing physical exercises have lots of advantages.

First of all, doing exercises in the morning will refresh my body as well

as give me a good appetite to eat my breakfast. What’s more, the air in the

morning is really fresh and clean, so I can keep my mind clear and sound in the

class. By doing physical every day I can keep my mind alert that I can finish my

tasks in time. If I do not do any physical exercise, I will feel tired and my

body becomes quite sluggish. During the night, I may find it becomes harder to

fall asleep. Second, doing exercises everyday will help me to mound a better

personality. It takes time and patient to do exercises. Sometimes I just want to

give up, but my friends encourage me to carry on, then I feel a lot of

satisfaction. Doing physical exercises makes me stronger and healthier. That’s

my personal experience.

As a student, sports are indispensable. You can pick up your favorite sport

and do it every day. Only in this way, you can have both pleasure and a healthy

body.
