1. The effects on the respiratory system. Haze composition is very

complicated, including hundreds of atmospheric chemistry particulate matter.

Which is bad for your health mainly aerosol particles less than 10 microns in

diameter, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol

particles, fuel and car exhaust, etc, it can directly enter and adhesion in the

human respiratory tract and alveoli. Especially the submicron particles are

deposited on upper and lower respiratory tract and alveolar, causes the disease

such as the acute rhinitis and acute bronchitis. For obstructive bronchus

asthma, chronic bronchitis, emphysema and chronic respiratory diseases such as

chronic obstructive pulmonary disease patients, haze weather can make the

illness acute or acute exacerbation. If this kind of environment will cause lung

cancer for a long time.

2. The effects on the cardiovascular system. Haze weather pollutants in the

air, air pressure is low, easy to induce acute cardiovascular disease. Such as

heavy fog, the moisture content is very high, if people in outdoor activities

and sports, the bodys sweat is not easy to discharge, cause people bosom

frowsty, increased blood pressure.

3. The fog haze weather can also result in close formation ultraviolet

weakened, activity of the infectious pathogen in the air, increase of infectious

diseases.

4. Reduce because of the fog the sun, ultraviolet irradiation in children

is insufficient, inadequate vitamin D in the body to generate, the absorption of

calcium significantly reduce, serious can cause rickets in infants, childrens

growth to slow down.

5. Affect mental health. Heavy fog weather depression, due to weak light

and easy to let a person produce mental laziness, depression, and pessimism,

encounter something goes wrong and even easier to spin out of control.

quality is poor, easy to cause traffic jams, traffic accidents.

Bike-sharing has been advocated by the government in recent years. It

offers help to the people who is in a hurry to reach the destination soon, the

more important is to let more people back to the simple traffic style and reduce

private cars, so as to protect our environment. But some people make use of this

policy to take advantages of others. News report that some middle age men and

women force people to give charge after finishing using bike-sharing, because

they look after the bikes. It is known to all that bike-sharing is free, which

is the convenience government offers to the public. It is ridiculous to charge.

When the news exposed, the public know the truth and the ones who take charge

are criticized. Under the government’s supervision, now bike-sharing is more

popular.

At present, many teenagers smoke. I dont think its a good phenomenon. It

must be stopped, for smoking is harmful in many ways.

First, smoking is bad for our health. As we start smoking, its so

difficult to give up, because the tobacco contains a drug called nicotine, which

can get us into the habit of smoking. When we go without nicotine, our bodies

will feel sick.

Second, smoking is so dangerous. When we smoke in bed, we may kill

ourselves as well as burn down our houses, for burning cigarette ends may cause

a big fire. And if we threw the cigarette ends anywhere, it would also cause a

fire disaster.

Furthermore, once we smoke in public, we may make other people feel

uncomfortable as well.

Accordingly, for the sake of your and others’ health, please dont

smoke.

My mother high stature, not fat or thin, a few silk shallow wrinkles on the

forehead, often hang a smile on his face.

Mother is kind, she taught me at an early age to be honest, treat people to

be generous, since the childhood to cultivate my good character.

Remember there is one thing I always forget. It was a hot afternoon, the

sun like aball of fire to bake the earth. I do in the room, fan fan, but sweat

kept rolling down. I said to mother: "mom! The weather was too hot, hot as hell!

I want to eat Popsicle." Mother said: "go, Ill take you to buy some ice stick."

Then picked up a wallet.

Where to buy, I chose a Popsicle, mother from the purse and took out a

piece of 50 yuan to buy the ticket of uncle, uncle to find the money, my mother

and I went hurried home.

At home, mother put back counted, soliloquize ground to say: "yi? Well,

there are 7 yuan, how do I find 45 yuan?" Once I listen to and happily say:

"good! People buy really confused, looking for more 3 yuan. Mom, the 2 yuan to

me?" Mother stared my one eye, said angrily: "find the 2 yuan more, we should

give the money back, do not want the covet petty gain! Besides, somebody else

sell Popsicle more not easy!" Say that finish, mother take fire up the sun, give

somebody else sent 3 yuan.

The moment I stepped in high school, I have made up my mind to study hard

for the purpose to enter a good university. In the first year, I made a lot of

new friends. All of them were so excellent that I wanted to learn from them. As

the second year has come, I felt great pressure. My scores went up and down and

I felt so worried. I told myself that I should find a way to relieve pressure.

Listening to music was a good way. I would sing with the music and shake my

body, which made me forget everything but the joyous music. Second, I would like

to talk to my friends, because they understood me. We would have some tea in the

shop and then shared our secrets. When we laughed out loudly, all the annoyance

would disappear.

Today, as our economy develops fast, people live a much better life than

before, they start to pay attention the chase fun. When people have holiday,

they will choose to travel, most people will give money to the organization,

while some people choose to self-helptraveling. Self-help traveling can save a

lot of money, people can save the money which is given to the tour guide. What’s

more, self-help traveling can bring people a lot of fun. People can visit the

site as long as they want, sometimes they can find the interesting things in the

small place. While the tour guide will always take people to the commercial

place. Self-help traveling is becoming more and more popular now.

Last Qingming Festival,i return home to worship my grandfather.Qingming

Festival is a folk Festival.In the past,the Qingming Festival was called "Arbor

Day". But Today, Chinese visit their family graves to tend to any underbrush

that has grown. Weeds are pulled, and dirt swept away, and the family will set

out offerings of food and spirit money. Unlike the sacrifices at a familys home

altar, the offerings at the tomb usually consist of dry, bland food. One theory

is that since any number of ghosts rome around a grave area, the less appealing

food will be consumed by the ancestors, and not be plundered by strangers.

With the passing of time, this celebration of life became a day to the

honor past ancestors. Following folk religion, the Chinese believed that the

spirits of deceased ancestors looked after the family. Sacrifices of food and

spirit money could keep them happy, and the family would prosper through good

harvests and more children.

With the coming of the NewYear.People all over the country are immersed in

an atmosphere of happiness. In the meantime,a war without smoke is about to

begin. In WuHan,CHINA.Because people are greedy and do not take the law

seriously,people were infected with the new virus from the wild animal.The virus

spreads very quickly.Many people died in a short time.WuHan has become a major

disaster area.After a short while,the virus began to spread throughout CHINA.The

stmosphere of happiness was gradually replaced by panic and sadness.It is the

Spring Festival holiday,the turnover is huge.This make the disease more

difficult to control.The national government took active measures to control the

disease.In these difficult times,we know and familiar with many selfless

people.They are front-line workers,hard working behind the scenes,medical staff

volunteers and so on.Even the elderly ZhongNanShan academician also insisted on

the first line.People all over the country donated money and materials for the

disasterareas.They all have a heart of dedication and responsibility.The whole

nation is confident to win the war without smoke.Behind this outbreak we see the

unity of chinese people.It also sees some serious problems.Many people dont

obey the law and take chances.To some extent,this is reflected in the inadequate

supervision of some national departments.I sincerely hope that the state

department will improve their supervision.Let lwabreakers have no opportunity to

do some harmful things.As a chinese citizen,we must obey the law and spread

positive energy in society.As the new youth of the new age,we should actively

maintain social harmony and contribute to the prospercity of the country.

随着新年的到来，全国人民都沉浸在幸福的气氛中。与此同时，一场没有硝烟的战争在中国武汉即将开始。由于人们贪婪，不重视法律，人们被从野生动物身上感染了这种新病毒。病毒传播很广快点。很多人们很快就死了。武汉成了大灾难区域。之后不久，病毒开始在中国各地传播。快乐的气氛逐渐被恐慌和悲伤所取代。正是春节长假，人口流动量巨大。这使疾病更难控制。那个国家政府采取了积极措施控制这种疾病。在这个困难时期，我们认识并熟悉许多无私的人。他们是一线工作者，在幕后埋头苦干，医务人员志愿者等等开。甚至老钟南山院士也坚持在一线。全国人民为灾区捐款捐物。他们都有一颗奉献和责任心。全国人民都有信心赢得这场战争烟。在后面这次爆发，我们看到了中国人民的团结。它也看到了一些严重的问题。很多人们不遵守法律，冒险。这在一定程度上反映在一些国家部门监管不力。我衷心希望国务院加强对他们的监督。让我们的人没有机会做一些有害的事事情。比如作为一个中国公民，我们必须遵守法律，在社会上传播正能量。作为新时期的新青年，我们要积极维护社会和谐，为国家富强作出贡献。

Every day, we can see the figures of the volunteers. Actually, they have

formed a kind of scenery of the city. Some people hold that volunteering is

merely a waste of time, because the volunteers have no gains with pains.

However, I believe that doing voluntary is quite rewarding.

In the first place, we can put into practice what we have learnt before,

for instance, when we were asked by a foreigner about the way to some place, we

could practice our oral foreign language, it’s definitely a good opportunity to

express ourselves in a foreign language correctly and clearly.

In the second place, we could make a lot of new friends while we are

volunteering As a proverb says, “At home one relies on one’s parents and outside

on one’s friends”, so it is never a bad thing to have lots of friends.

Finally, helping others is a good way to make you feel happy and when you

help others solve a problem successful, you will feel fulfillment. In this

sense, we reap a bountiful spiritual harvest by doing voluntary work.

On the whole, we can benefit a lot by engaging ourselves in the voluntary

work. Therefore, I suggest those that have abundant spare time registering as

volunteers for the welfare for the public.

Each people all have own dream, also have a dream in my heart, it deeply

buried a pregnant with my ideal seeds, in my heart to take root, sprout.

Each people all have own dream, some people want to be a writer, someone

wants to be a pilot, someone wants to be an astronaut, I want to be a human

engineer teachers. Someone may ask me: "when the teacher have a good, low wages,

work hard again, still not taken seriously by people", "the home has five grain,

improper king" but has it ever occurred to you, if there is no teacher to teach

knowledge, then we wouldnt it be a fool, because with the teacher teach us

knowledge, we human beings can become more and more intelligent, more and more

developed, it is because the teacher has given us a seam, we can swim in the sea

of knowledge. During the day, the teacher standing on three feet platform for us

to the lecture; Night, the moon has climbed up the tree, but the teacher in the

flickering light of hard exercise books for us on the road the bright red

tick... Maybe when one is surrounded by the joy of success, he would forget

their loved ones, but he will never forget my teacher, because he has a

teachers success is a credit.

I also is same, no matter how I look, how far, I will not forget my

respected teacher, because I am in the teachers care, love grow up under the

influence of bath, wherever I go to the end of the world will not forget their

own teacher, so I aspire to the teacher the profession. Now I was a pupil, I

must be hard, study hard, study hard, grow up to go in the dream three feet

platform.

I am in primary school now, and I like my campus so much. The first time I

walk in the school, I am attracted by its beautiful scenery. There are so many

green trees and colorful flowers around. The environment here is so lively. So

many students do the sports in the playground. The comfortable environment makes

me study in good mood.

After I go to school, teachers always tell me to study hard, so that I can

be the excellent student. But now I have grown up, I have my own idea. The

reason for me to study hard is to return my parents’ love. When they are old, I

can make a lot of money and let them have a better life.

Nowadays, there is a growing focus on health care. People are pursuing a

healthy lifestyle. A healthy diet is one of the most important parts of it. As

the saying goes, bread is the staff of life, eating healthily and deliciously is

the goal we pursue. From my point of view, in order to build healthy eating

habits, we should eat more vegetables and less fat and sugar. Vegetable is the

best source of s vitamin, because vegetables are rich in vitamins. Among them,

vitamin C and vitamin A are the most important. Too much fat and sugar can lead

to obesity, which is harmful to health. Besides, eating more fruits and drinking

more water is of great help.

The Spring Festival, Chinese New Year,is the most important festival for all of us. All family members get together on New YearEve to have a big meal.At the same time, everyone celebrates to each other.At about 12 oclock,some parents and children light crackers.The whole sky is lighted brightly. We may watch the fireworks excitedly.How busy it is!

On the first early moring of one year, many senior citizen get up early and they stick the reversed Fu or hang some couplets on the front door. Some houses windows are sticked on red paper cutlings.

The Chinese New Year lasts fifteen days. So during the fifteen days, we always visit our relatives from door to door. At that time, children are the happiest because they can get many red packets form their parents,grandparents, uncles, aunts and so on. The last day of the Chinese New Year is another festival. It names the Lantern Festival.

So the Chinese New Year comes to the end.

春节，中国新年，是我们大家最重要的节日。所有的家庭成员都得到新大吃一顿。同时，大家互相庆祝。大约十二点，一些家长和孩子们放鞭炮，天空是明亮的。我们可以兴奋地看烟花!

在一年的第一个清晨，许多老年人早早起床，贴上颠倒的礼物，或在前门挂上对联。一些房子的窗户上贴上红纸。

中国新年持续十五天。所以在这十五天里，我们总是登门拜访我们的亲戚。那时，孩子们最快乐，因为他们可以从父母、祖父母、叔叔、阿姨那里得到很多红包。春节的最后一天是另一个节日。它把元宵节命名为元宵节。

所以中国新年就要到了。

Hometown is the place where a person belongs. Chinese people have special

feelings about their hometown. No matter where they go, they won’t abandon it

and always make some time to visit. My hometown brings me so many happy memories

and I wish it could keep its original face forever.

Two years ago, I lived in my hometown. It is a small village, so people

there get familiar with each other. When we walked on the country road, everyone

smiled when we saw each other. There was no distance for us. In the daytime, I

liked to go boating in the small river with my friends, or sometimes I could

catch fish. The green trees around me and I could hear the birds singing all the

time. It was a paradise for me.

However, even the small paradise can’t avoid being polluted seriously. The

environment is no more clean, the river becomes smaller and the water is so

dirty. When I see this, I feel so pity. If we lose the clean land, how can we

survive for long. Protecting the environment is in need.

Recently,haze weather has become a daily one right here in large part of

China.People are forced to wear the mask to avoid breathing poisonous air.So it

is necessary to find out the reason why leads to that and work out the

resolution.If we trace the cause for haze weather ,the main points are as

follows ,first,china s air quality standards are rather lax and evaluation

factors are limited,so you will see that current air appraisal system has

defects.Second,some people just go for economic interests instead of turning out

products according to relevant law and regulations.They tend to use obsolete

equipment in which they are high likely to emit a great deal of wasted air.

Third,across our society ,relevant protection awareness has not built up so

that people havent formed a habit of using green product and saving energy as

much as possible.Just for the sake of convience to go out,people rely more and

more on travelling and working by car while car is the main cause for the haze

weather

To settle this problem,a series of meaures should be taken as follows.First

,we should strengthen air monitor to lower the levels of small particulate

pollutants.Second,we should enact more strict laws and regulations and keep

perfecting our current law on environmental protection to regulate people s

daily action and the industrial production and punish those factories that

ignore the protection and keep emitting dangerous material that cause haze.

Third,we should develop green and energy-saving energy to lower the

emission of haze and improve air quality.As far as i am concerned ,if we work

together to be able to do such measures ,our environment will getting better and

better and haze weather will vanish completely.

Since I was small, I have heard about the Great Wall, it is very long, a

lot of people come to Beijingto watch it. In China, there is an old saying“One

who fails to reach the Great Wall is not a hero”. As it is so famous, I want to

the site when I have a chance. I see many pictures about the Great Wall on the

books, I also watch it through TV. Every time I see it, I feel so eager to reach

there. My father traveled there once, he took many pictures, this is the first

time I feel so close to the site. I must work hard, so I can have money to go to

there.

Today, cellphone has been part of people’s live, they use cellphone to keep

in touch with friends and family, cellphone is also very helpful in people’s

work. As cellphone is so important, so people count on it so much, I think we

need to take the right attitude towards cellphone.

Teenagers especially like to use cellphone, they can’t live without

cellphone. Take my brother for example. He carries cellphone all the time, no

matter what he does. When we are talking to him, he just lows down his head and

says yes, I don’t think he is listening to us. When he is walking on the street,

he still keeps his eyes on the screen. My brother is a typical cellphone user, I

feel pity for him because he misses so many beautiful moment.

It is very a common situation for the young people to low down their heads

to check on the cellphone. They don’t have the real communicate with others, it

is not a good behavior. It is better to drop down the cellphone and see the

scenery around us.

When asked about their opinion of career and family, people always respond differently. Some people deem it more important to pursue their career, while there are always other people who argue that family should be the number one in one’s life.

It goes without any question that career plays a key role in our life. In the very first place, career can give us an aim to live on. Without career, much of our living time will be certainly wasted. What’s more, career can provide us with a means to live on. Most of the people earn their income from a job. On the other hand, family is also an indispensable part of life, as many people will admit. Family is always regarded as a place where we can escape from troubles in life. In addition, we can obtain a sense of belonging to from family. Without it, anyone will feel lonely and desperate.

In my opinion, career and family are not in opposition to each other. Rather, they can enhance each other so that one’s life can become better and better. Therefore, it’s not a choice between right and wrong, but one between ideal and practical.

在谈到自己的事业和家庭的意见要求，人总是有不同的反应。有些人认为这更重要的是追求自己的事业，而总有那么谁认为家庭应该是一个人的生活的人数1人。

毫无疑问，任何事业在我们生活中起着关键作用。在第一个地方，可以给我们一个职业生涯的目标是生活。没有职业生涯中，大部分时间我们的生活一定会被浪费。更重要的是，职业生涯可以提供一种手段，对我们的生活。大多数人从工作中赚取的收入。另一方面，家庭也是生活中不可缺少的一部分，因为很多人会承认。家庭一直被认为是一个地方，我们可以摆脱生活中的麻烦。此外，我们可以得到一个属于家庭的感觉。没有它，人会感到孤独和绝望。

在我看来，职业和家庭是不反对对方。相反，它们可以加强彼此，使自己的生活能够越来越好。因此，它不是对与错之间的选择，但理想和现实之间的一个。
