Many people ask what happiness is. I don’t know why there are many people

asking this question, because I think happiness is simple. As for me, I feel

happy when I do a good job in my study. Teachers praise me and my parents are

happy. Or, when I help others I feel happy. I am proud of myself. Besides,

playing with my classmates or friends is happy, too. We always have a great time

together. From above, they are all happiness.

because their main goal is to enter the college, so they need to work so hard.

As the saying goes "qiu dong smog knife to kill". We can see and catch

"smog" actually have bigger influence on the body, especially the high incidence

of respiratory and cardiovascular and cerebrovascular diseases in the elderly

group.

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

It is reported that thick fog and haze surround many parts of China. People

have to wear masks when they go out.As air pollution is getting increasingly

worse,it has become the main concern of people.

Air pollution can have serious consequences for human’s health and also

severely affects natural ecosystems. Millions of people die of illnesses related

to air pollution every year.Due to particles from exhaust emissions,green house

effects result in warmer weather,acid rains corrode the earth,and frequent haze

causes traffic problems.

Confronted with such situation,positive measures should be adopted. The

government should keep its regulatory role for properly supervision. Related

rules should be made out for reducing emissions of new vehicles and limiting

high-emission vehicles.Factories should meet standards for curbing emissions of

pollutants in surrounding cities.Meanwhile, provinces and municipalities in each

target region should set up a mechanism for the joint prevention and control of

air pollution.

At the coming of the new year, it is also the time for one of the biggest

tennis matches, the Australian Open. Since Li Na won her second grand slam here,

more Chinese people fall in love with tennis. One of the popular male players,

Roger Federer, who is more than 30, but he is still in the top level. The fans

hope their hero can enjoy the match and they didn’t expect the next grand slam.

But Roger made it happen again. He defeated his great rival, Nadal and won

Australian Open. The world was cheering for him, and they witnessed this great

man to make his career successful at the old age. If we have dreams, it is never

too late to pursue. People always take the age as the excuse, actually, they

lack of persistence, which differs them from successful men.

There are four seasons in a year.They are spring,summer,autumn and

winter.Every season has three months and each month has about thirty days.

The first season is spring.In spring time we have warm weather and sunny

begin to sing their songs.Everything comes to life again.

The second season we call summer.In summer the weather is very hot and it

rains a lot.All trees are beautiful with their green leaves.The sky is very

clear and blue,and the sunshine is much stronger than that in other seasons,so

many people go to the seaside or the mountains to avoid the heat.

Autumn is the third season of the year.In autumn the weather becomes cooler

day by day.It is the best season we have.So many people like it very

much,especially the farmers.They are very busy with their harvest.

The last season is winter.It comes with frost and snow.The weather grows

colder and colder,and much snow falls.But winter is not very long with us,for

spring comes again soon.

It is well known that exercise is important. In our school, we have to do an hours exercise every day. Many students are very happy. In the one hour, some of us play basketball, football and ping pong, and some run around the playground. Everyone is talking and laughing. I love this activity very much. I also hope that there will be more and more sunlight sports in our life after school. That not only makes us happy, but also makes our body healthier.

The sun shines on us. It gives us light and heat. It makes everything grow.

It gives the earth life.

The earth turns round itself. As it turns, we have day and night. It’s

bright by day and dark by night.

The earth also travels round the sun in an orbit. As it travels, we have

four seasons. It is hot in summer and cold in winter. the days are long in

summer and short in winter. In spring it is warm and the days are getting

longer. In autumn it is cool and the days are getting shorter.

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.

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.

Recently, the news about the famous fast food company got bankrupted in

Taiwan was spread in Wechat. While in mainland, less people know about the truth

and the fast food company still works well. Chinese food problem exists all the

time, even the government has made some rules to forbid the illegal business,

still many manufacturers produce bad food for making more profit. The fast food

company doesn’t care about the market in Taiwan. Its spokeman said that their

main market was in mainland, and a lot of people were eating their food. Hearing

this, we surely will be angry. If everybody join the team to refuse to buy their

products, then the fast food company will be kicked out. Only in this way can we

protect our health and benefit.

In North, when winter comes, the weather is very cold, the cloud covers the

sunshine all the time, it is hard for people to see the sunshine. So the

sunshine becomes very rare in the winter, when it comes, I will feel very

comfortable, my mood turns good even I am not happy. I love sunshine, it just

like the hope for me.

Ladies and gentlemen,

I feel it a great honor to have a chance to give a speech here, talking

about the haze weather, which causes lots of bad effects on our health and life.

We breathe polluted air, making us suffer from lung and liver diseases. Besides,

because of it, the flights have to be canceled. All kind of transports may run

into each other, resulting in much damages and lots of injuries.

As far as I am concerned, it is high time that we did something. As

individuals, we should ride the underground or buses instead of cars to reduce

carbon dioxide. As government, more measures should be taken by carrying out the

related law on pollution.

In summary, we’re all looking forward to breathe fresher air and live a

happier life. Everyone should be a part of this job.

Thank you for your listening.

十月一日正好是国庆节，也就是祖国妈妈的生日。

每当国庆节来临之际，单位的门上挂起了灯笼，甚至上面都插上了彩旗，门上还张贴了“欢度国庆”四个大字。公园、大街小巷的树上都挂了灯笼。街道两边都摆满了五颜六色的鲜花。到处洋溢着节日气氛。

为了迎国庆，我们有的写作，有的画画，并且要从里面选出几个最好的作品贴在后面，办一个国庆专栏，作为送给祖国妈妈的生日礼物。

祝祖国妈妈生日快乐!

I wish my mother a happy birthday!

Every child needs to receive education and they spend so much time to learn

knowledge, whether they are like or not. The adults always tell their children

that as they are young and full of energy, so they should learn knowledge and

skills, but most kids dont know the necessity of study. The most important

reason to study is to keep pace with the time. We live in the society that we

need to make connections with others. If we dont get the newest information, we

will be kicked out and have no idea what they are talking about, then isolation

happens. Whats more, when we are equipped with skills, we can make our choices

and take charge of our life. In order to live the comfortable life, we must

study hard and fight for our future.

The Mid-Autumn Festival

The Mid-Autumn Festival is a very important Chinese festival. It falls on

the 15th day of August. A few days before the festival， everyone in the family

will help to make the house clean and beautiful. Lanterns will be hung in front

of the house.

On the evening there will be a big family dinner. People who work far away

from their homes will try to come back for the union. After dinner， people will

light the lanterns which are usually red and round. Children will play with

their own toy lanterns happily.

At night the moon is usually round and bright. People can enjoy the moon

while eating moon-cakes which are the special food for this festival. They can

look back on the past and look forward to the future together. It is said that

there was a dragon in the sky. The dragon wanted to swallow up the moon. To

protect the frighten the dragon away.

中秋节是中国一个很重要的节日，在八月十五号。在节日来临的前几天，家庭中的每一个人都帮着打扫房子，把房子装扮得漂漂亮亮的，灯笼挂在屋前。

晚上有一顿美餐，离家在外工作的人也要回来团圆。晚饭后，人们点亮灯笼，一般是红色的圆灯笼。孩子们会高高兴兴地玩他们的玩具灯笼。

晚上月亮又圆又大，人们在赏月的同时吃着中秋节特别的食品——月饼。人们在一起回顾过去，展望未来。据说天上有一条龙，它要把月亮吞下去。为了保护月亮，孩子们要弄出很大的响动把龙吓跑。

Since we go to school, we are taught that no pain, no gain, it means that

if people want to be successful, they must work hard. But the truth is that not

everyone can get what they want, even they work hard so much, but if working

hard does not bring success, why should they still need to work hard. In my

opinion, working hard doesn’t mean the person can success certainly, success

needs more factors, like the time, the luck and other things. There is no doubt

that if the person does not work hard and fight for his goal, there is no way

for him to get what he wants. Some actors start their career at the very young

age, when they are also 40, they become famous suddenly, if they give up, they

can’t be waiting for their reputation. So working hard, there is much chance to

get succeed.

Dear Jim,

I’m writing to tell you more about the new form of sharing bike--mobike

mentioned in your latest letter.

It’s very convenient to use if you have a smartphone. What you do is to

find a nearest mobike through the APP, scan the QR code on the bike, and enjoy

your trip.

Compared to other forms of sharing bike, the greatest advantage of mobike

is that you can easily find one and never worry about where to park it. It is

becoming a new trend as a means of transportation, which relieves the traffic

pressure and does good to the environment as well.

Hope to ride a mobike with you in China.

Yours,

Li Hua

Study has been the necessary part of humans life. Many students take it as

their duty and they dont realize the meaning of study. Most people believe that

the purpose of study is to master some skills and make money. This is the basic

function of education. I believe that the further meaning is to teach people the

way of thinking. If there are two jobs, one is to sell pastry for 12 hours, and

the other one is to work in the office for 8 hours, but the former can earn

double income. The young people will surely take the second job, because they

need more private time to do their own things. They have more things to chase

besides making the ends meet.

My summer holiday begun on July 7th.I love summer holiday because I dont

My plan for August is travelling.I travel with my family every summer

holiday.I like travelling because I can go to different places and meet

different people.Sometimes I make good friends during the journey.And its very

sad to say goodbye to them when the journey ends.
