keep healthy英语作文20篇

In the past few decades, our Earth has changed a lot, but to the bad

direction. Among these changes, the air pollutions resulting from a huge number

of automobiles and coal-burning is almost the severest. The severe air pollution

alarms humans of the heavy load we have exerted on Earth by our insatiable

production and usage of automobiles. However, with the deepening of

urbanization, more cars are needed, which will make the air pollution worse.

Therefore, the following actions should be taken. First, we should apply the

most cutting-edge technologies in order to adopt new forms of energy as

substitutes for fossil fuels. Second, try hard to develop possible

transportation means, which are enviromental friendly. So that the citizens can

reduce the dependence on cars. In short, our humans should take responsibilities

for the air pollution and have to find ways to solve this problem.

Nowadays, smart phone has been part of our life. We can see people lowing

down their heads and playing smart phones all the time. When people are walking

on the street, the traffic regulations are no longer their first concern. It is

so dangerous for them to keep their attention on the phone. Dutch officers

figured out a new rule to let people realize the traffic lights. On the ground,

the traffic light can be seen. What a smart idea. When people are watching smart

phones, they can see the lights, too. At the same time, we need to think about

the problem that whether our life is controlled by the technology.

Christmas Day is very popular around the world, when that day comes, we can

see the Christmas products sell everywhere, though Christmas Day is not

originating from China, in our country, more and more people spend that day. A

foreigner pointed out that Christmas meant to be grateful for them, while for

Chinese people, it was just a day for celebrating. To me, Christmas indeed means

a day to have fun.

When I was small, I did not have the concept of Christmas, because in my

mind, I only knew Chinese traditional festivals, I liked Spring Festival best, I

could get a lot of money from parents. When I went to high school, all of my

friends would talk about Christmas Day when the day was near, so I started to

know it. Almost every young people like Christmas, but if you ask them what the

meaning of the day, less of them can answer.

The meaning of Christmas Day is to remind people of Jesus’s birth, it is so

important for the western people, but for me, I only want to have fun, everyone

is celebrating it, so I join them, being happy, that’s enough for me.

In addition,() I insist on do some physical training such as running, and

Throughout history man has changed his physical environment in order to

improve his way of life。 With the tools of technology he has altered many

physical features of the earth。 He has transformed woodlands and prairies into

farms and made lakes and reserviors out of rivers for irrigation purposes or

hydroelectric power。 Man has also modified the face of the earth by draining

marshes and cutting through mountains to build roads and railways。

However， mans changes to the physical environment have not always had

beneficial results。 Today， pollution of the air and water is an increasing

danger to the health of the planet。 Each day thousands of tons of gases e out of

the exhausts of motor vehicles。 Smoke from factories pollutes the air of

industrialized areas and the surrounding areas of the countryside。 The pollution

of water is equally harmful。 The whole ecological balance of the sea is being

changed and industrial wastes have already made many rivers lifeless。

Now environmental protection is more pressing than ever before。 As we know，

massive destruction of environment has brought about negative effects and even

poses a great threat to mans existence。 Indifference to these problems will

mean mitting suicide。 Therefore， effective measures should be taken and laws

passed to conserve environment。 Otherwise，man is certain to suffer from the

serious consequences caused by this lack of care for his living

surroundings。

From this incident，we can see that there are still more things to be done。

Firstly，the government needs everything possible to ensure the quality of

products，particularly the safety of food as this concerns everyones

life.Secondly，as for the producers，it is very important for them to be morally

honest. They should never try to pursue profit or economic growth at the expense

of health and life of people. Thirdly，we consumers must attach importance to the

things we eat and develop an awareness of how to protect our legal rights if

cheated。 Only in this way will we be able to build a more secure and harmonious

society.

As the technology and economic is developing, the environment problem is

becoming a severe problem, and the people are seriously affected.

The sustained damage to the environment has caused a serious problem, such

as air pollution, sand storm, extraordinary weather, and diseases etc., people

suffer from what they have done to the environment.

However. People have realized that it will be too late if they don’t do

anything to prevent things from getting worse. For example, there is an “Earth

Hour” on a Saturday of March of each year. It is a global movement, usually it

lasts from 8:30pm to 9:30pm. It is also called “Light-off for One Hour”. During

this hour, all the light will be turned off. The purpose of this movement is not

only to save energy, but also to warn the people to realize the importance of

protecting the mother earth, and to stop violating the environment.

Anyway, people and the environment have to keep a balance relationship.

People take from the environment, and have to protect it too.

The Great Wall of China is called the "Ten thousand Ii Great Wall" in

Chinese. In fact, it s more than 6 000 kilometres long. It winds its way from

west to east, across deserts, over mountains, through valleys till at last it

reaches the sea.It is one of the wonders of the world.The Great Wall has a history of over twenty centuries. The first part of it

was built during the Spring and Autumn Period.

During the Warring States Period, more walls were put up to defend the

borders of the different kingdoms.It was during the Qin Dynasty that the kingdom of Qin united the dif ferent

parts into one empire.

To keep the enemy out of his empire, Emperor Qin Shi Huang had all the

walls joined up. Thus, the Great Wall came into being.The Great Wall is wide enough at the top for five horses or ten men to walk

side by side.Along the wall are watchtowers, where soldiers used to keep watch.Fires were lit on the the towers as a warning when the enemy came.It was very difficult to build such a wall in the ancient days without any

modern machines.

All the work was done by hand. Thousands of men died and were buried under

the wall they built. The Great Wall was made not only of stone and earth, but of

the flesh and blood of millions of men.

Today the Great Wall has become a place of interest not only to the Chinese

but to people from all over the world. Many of them have come to know the famous

Chinese saying: "He who does not reach the Great Wall is not a true man."

In the current society, with the rapid development of the Internet,

shopping on the internet has been a fashion especially among the youngsters.

Online shopping has made our daily life become more convenient and feel

comfortable. In the first place, shopping on the Internet can save much time so

they would be able to concentrate more time and energy on their academic study.

In the second place, the Internet has provided kinds of goods to consumers, and

we can save much money through online shopping.

However, every coin has two sides, online shopping also has shortcomings.

We maybe buy some fake products online because of lacking of the face to face

communication with sellers. What’s more, the delivery will increase the risk of

items’ damage.

Weighing up these two arguments, I prefer the former, because shopping on

the internet has become more and more important to us in our daily life. We

should follow the footsteps of the times.

thousand five hundred years; Its main traditional cultural activities are:

The tang dynasty poet tu mus poem "qingming" : "rains fall heavily as qingming

One day during the summer vacation, my father and I agreed to play

badminton, so we went to guolin park with badminton and racket.

The scenery of the park is picturesque, there are colorful flowers, and

some flowers are fragrant and beautiful. We came to a clearing and put the bag

on the lawn. Starting to play, the father said, "take the ball in your left

hand, take the beat in your right hand, and throw the ball gently at the beat of

the ball and hit the ball towards the other." I cant serve at the beginning,

also wont catch, serve as dad said practice is much more skilled practice, but

the other ball back, I was a little bad. I was a little frustrated by this, but

I thought: once you do something, you must do it well! So I trained again. I was

able to catch my dads ball very well, and my father praised me for saying that

the more I played the better, I was so happy.

Recently, we often show that shopping online is better than in store, but

is this really the case? Actually, there is no consensus of opinions among

people as to the view of shopping online is better than traditional shopping.

Some people consider that online shopping will replace the mall shopping, stores

will disappear in the future, while others argue that stores would unlikely to

be disappeared, it has its own advantages.

Most people shopping online because it is very convenient, there is no need

to go out, just click the mouse gently, they can buy the goods they want. In

addition, goods online are cheaper than entity shop that buyers can save a lot

of money. But even the coin has two sides. Online shopping also has advantages

and disadvantages. In recent years, we see a lot of news about online cheating,

and many buyers complain about poor quality of the goods, which is different

with the description.

However, the situation above is rare in traditional shopping store, because

the guest can communicate with the seller face to face. Buyers can also see

goods intuitively. But the traditional shopping does not convenience as well as

online shopping, for example, if people meet a traffic jam on the way to the

shopping which will affect the happy mood of shopping.

As we all known，food safety problems are more and more popular in our

country，because more cases about food safety problem have appeared.

Firstly，As the old saying goes，the food is what matters to the people。 Food

plays an important role in peoples life。So food safety influences peoples

health and life。Secondly，some producers only think about earning money without

thinking about ensuring food safty。they produce unqualified food.Thirdly， some

food supervisory departpents dont perform their duty pletely。This behavior make

some producer ignore the safety of production.

If we want to solve problems that is illustrated former，we must call on the

supervisory department to manage the food market.And the producers must paly

their roles。 Lastly， we hope that there is law that punish illegal acts.

TheTimeof a date has different standard for boys and girls. Girls always

like to be late for about ten minutes while boys always reach the destination on

time. If the girls are earlier than the boys, then the situation will become

awkward, it is not polite to let a girl wait for a boy. But sometimes girls are

always late for more than half an hour, which annoys the boys. It is said that

if you call a girl to ask her if she is on the way, then she will answer you

that she just goes out of the house, the truth is that she is still in the

house. Most girls are late for making up for a long time. It is considerate to

be late for a date for a few minutes, but it is impolite to be late for much

time.

I am a third year master major in automation at Shanghai Jiao Tong

University, P. R. China. With tremendous interest in Industrial Engineering, I

am writing to apply for acceptance into your Ph.D. graduate program.

Education background

In 1995, I entered the Nanjing University of Science & Technology

(NUST) -- widely considered one of the China’s best engineering schools. During

the following undergraduate study, my academic records kept distinguished among

the whole department. I was granted First Class Prize every semester,In 1999, I

got the privilege to enter the graduate program waived of the admission

test.

At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5%

in the department. In the second semester, I became teacher assistant that is

given to talented and matured students only. This year, I won the Acer

Scholarship as the one and only candidate in my department, which is the

ultimate accolade for distinguished students endowed by my university.

Presently, I am preparing my graduation thesis and trying for the honor of

Excellent Graduation Thesis.

Research experience and academic activity

When a sophomore, I joined the Association of AI Enthusiast and began to

narrow down my interest for my future research. With the tool of OpenGL and

Matlab, I designed a simulation program for transportation scheduling system. It

is now widely used by different research groups in NUST. I assumed and fulfilled

a sewage analysis & dispose project for Nanjing sewage treatment plant. This

was my first practice to convert a laboratory idea to a commercial product.

In retrospect, I find myself standing on a solid basis in both theory and

experience, which has prepared me for the Ph.D. program. My future research

interests include: Network Scheduling Problem, Heuristic Algorithm research

(especially in GA and Neural network), Supply chain network research, Hybrid

system performance analysis with Petri nets and Data Mining.

Today is Mother’s Day. I know some of my classmates are going to help their

mothers with the housework, others .are going to buy some flowers for their

mothers. I want to say to her that I love her very much. But as a boy, it is a

bit difficult for me to show my heart. I think only girls can do that.

My mother is very kind. She takes care of me day and night.

She spends little money, but buys anything for me that I need.

This time I must show my love. I am going to give her a card and write like

this, "I love you, mother!" I am going to put it under her pillow.

今天是母亲节。我知道一些同学打算帮妈妈做些家务，还有一些同学打算给妈妈买些花。我只是想对妈妈说一声，我非常爱她。但是对我来说这样表达我的情感有点儿难，因为我是个男孩。我觉得只有女生才这样做。

我妈妈是个非常善良的人。她对我照顾得无微不至。她自己很少花钱，但能给我买我需要的任何东西。

这次我一定要表示我对她的爱。我打算送她一张写有“我爱你，妈妈”的卡片，我还打算把它放在她的枕头下面。

Sharing bike can be seen in every corner of the street, which is very

popular by the public. The foreigners speak highly of sharing bike, because they

can ride the bikes to look around the city and the expense is very cheap. As

people enjoy the convenience of these bikes, the problem comes. We can see that

many bikes have been broken and some are even put in the main road, which brings

trouble to the public. Of course when the media reported the phenomenon,

everybody condemned the negative behavior. Sharing bikes are public property,

all the people have the responsibility to protect them, so after using them, we

should just find a right place to lock them. The small act can present a

person’s nature, so dont let yourself be the rude one.

From the earliest time to the present days, viewpoints concerning human

nature were vehemently contended among prominent philosophers. Mencius believed

human nature is good, and people are naturally inclined toward virtue. While,

Xunzi deemed human are basically evil who need to be changed by man-made.

As it is widely known, human nature is that indestructible matrix upon

which the character is built. Accordingly, to a large extent, the basic nature

of human beings cannot be changed. On the other hand, each of us is naturally

endowed with diverse both qualities and personalities, which makes us unfold an

apparently distinct character. Then, it is hard for one to change his nature

fundamentally. Regardless of whether nature is innate or habitus acquired, they

were both a consistently developing courses that cannot be easily changed in a

short time. Last but not the least, external influencing factors, like

religious, education and even social institutions can merely direct our nature

on account of the most limited control. Thus, it is only the surface that is

capable of alteration, improvement and refinement.

In a word, the basic nature of human beings does not and cannot change and

also no one can fundamentally change his nature in the short time. But people

can make it perfect.

Today is March 8, International Womens Day is to commemorate the world of

working women to fight for peace and democracy, womens liberation struggle

holiday.

Since yesterday, I discussed with my father on how to make my mother happy

over the holiday. I would first make a suggestion: "Give my mother to buy a new

phone." Dad thought for a moment, said: "Mom bought a mobile phone soon, you can

use, there is no need to change." Dad said: "We go out to buy some cosmetics,

her mother there." I am opposed to: "Moms cosmetics too much, many of which are

not all useful." My Father and I are anxious, and in the end what got her point?

We simply asked her what he wanted bar. But my mother said: "I do not want to

buy, I just want to sleep." I do not know why my mother this way, but I know my

mother is very hard to control more than 300 college students, daytime talk,

meetings, writing papers, fill out information and give students lessons, etc.

in the evening and students should check the study up the bedroom. If it is me,

I would like the mother, in addition to want to sleep, the other wants to do

nothing.

However, I and Dad are determined to give my mother, "International Womens

Day" gifts, things came back to buy her mother was shocked at my father bought a

goggles and a pillow, my mother smiled.

I wish Mom "Womens Day" Happy!

People often say that gold and silver are the most valuable things in the

world.But

I dont think so. In my opinion, to read books is more valuable than

anything else.

The old saying “To open a book is always helpful” clearly tells us how good

it is to read a book.

Books are our friends. They introduce us different kinds of knowledge. They

lead us down the road to success.

Books are our teachers. They teach us troth, science, literature, and

philosophy of life. Besides, they increase our knowledge, enlarge our

experience,strengthen our character and do many other things which we can not do

without them.

Books tell us what is good and what is evil. And only books can tell the

good from the bad.

Therefore to read more books is the best policy for our young students.
