With the development of e-commerce, shopping online becomes a new way of

shopping which is getting more and more popular. Many citizens are likely to

shop through internet nowadays.

Generally speaking, shopping online offers lots of advantages with its

convenience the most prominent. There are many commodities on the internet where

you can search whatever you want. Besides, you just click the mouse can you get

all information you want, so that you don’t have to go to the shop personally.

In addtition, the commodities on the Internet is usually cheaper than the stores

which can save much money.

However, everything has two sides. You can not see the products or check

their qualities and some of the sellers on the Internet is not so honest. And,

for those who enjoys shopping around different stores, shopping online perhaps

will make them bored.

In my opinion, shopping online has more advantages than disadvantages, and

A fun-filled， pain-free lifestyle equaling happiness actually reduces their

chances of ever obtaining real happiness. As a result，many people avoid the very

attempts that are the source of true happiness.And the real happiness always

contains some pain .In the other hand， true happiness has nothing to do with

fun. All those who always have so much fun actually may not be happy at all.

I have a bitter experience. When I was a child， I lived a poor life，and I

had a happy and meaningful life in my childhood. And my parents were always

respecting each other. And now we have some money，and our life has improved a

lot. To tell the truth， it is a good thing. Unfortunately，My father always goes

out and takes part in the gambling activities. And my mother sometimes quarrels

with my father. I am extremely unhappy about it. I think money doesnt equal

happiness. And pain-free lifestyle also doesnt equal happiness. The real

happiness is that everyone loves each other， and does everything useful for our

society. Most of my classmates support me. But some of them think money is

everything. In my opinion，we cant do things without money. But money cant take

the place of everything，such as your life，your time and your happiness.

中秋节的传说 关于中秋节的英语作文

Mooncakes are to Mid-Autumn Festival what mince pies are to Christmas. The seasonal round cakes traditionally have a sweet filling of lotus seed paste or red bean paste and often have one or more salted duck eggs in the center to represent the moon. And the moon is what this celebration is all about. Mid-Autumn Festival falls on the 15th day of the 8th month，it is the time when the moon is said to be at its brightest and fullest.

There are two legends which claim to explain the tradition of eating mooncakes. One Tang Dynasty myth holds that the Earth once had 10 suns circling it. One day all 10 suns appeared at once，scorching the planet with their heat. It was thanks to a skillful archer named Hou Yi that the Earth was saved. He shot down all but one of the suns. As his reward，the Heavenly Queen Mother gave Hou Yi the Elixir of Immortality，but she warned him that he must use it wisely. Hou Yi ignored her advice and，corrupted by fame and fortune，became a tyrannical leader. Chang-Er，his beautiful wife， could no longer stand by and watch him abuse his power so she stole his Elixir and fled to the moon to escape his angry wrath. And thus began the legend of the beautiful woman in the moon，the Moon Fairy.

The second legend has it that during the Yuan Dynasty，an underground group led by Zhu Yuan Zang was determined to rid the country of Mongolian dominance. The moon cake was created to carry a secret message. When the cake was opened and the message read，an uprising was unleashed which successfully routed the Mongolians. It happened at the time of the full moon，which，some say，explains why mooncakes are eaten at this time. Mooncakes are usually stamped with Chinese characters indicating the name of the bakery and the type of filling used. Some bakeries will even stamp them with your family name so that you can give personalised ones to friends and family. They are usually presented in boxes of four which indicate the four phases of the moon. Traditional mooncakes are made with melted lard，but today vegetable oil is more often used in the interests of health. Mooncakes are not for the diet-conscious as they are loaded with calories. The best way to wash down one of these sticky cakes is with a cup of Chinese tea，especially Jasmine or Chrysanthemum tea，which aids the digestion.

中秋节吃月饼就像西方人圣诞节吃百果馅饼一样，是必不可少的。圆圆的月饼中通常包有香甜的莲子馅或是红豆馅，馅的中央还会加上一个金黄的咸鸭蛋黄来代表月亮。而月亮正是中秋节庆祝的主题。每年农历8月15日人们一起庆祝中秋，据说这一天的月亮是一年中最亮最圆的。

关于吃月饼这个传统的来历有两个传说。一个是唐朝的神话故事，说的是当时地球被10个太阳包围着。有一天10个太阳同时出现在天空中，巨大的热量几乎把地球烤焦了。多亏一位名叫后羿的神箭手射下了9个太阳，地球才被保住。为了奖励后羿，王母娘娘赐给后羿一种长生不老药，但是王母警告他必须正当使用。然而后羿没有理会王母娘娘的警告，他被名利冲昏了头脑，变成了一个暴君。后羿美丽的妻子嫦娥对他的暴行再也不能袖手旁观，于是她偷走了后羿的长生不老药，飞到月亮上逃避后羿的狂怒。从此就有了关于月宫仙子嫦娥，这个月亮上的美丽女人的传说。

第二个传说讲的是在元朝，朱元璋领导的起义军计划起义来摆脱蒙古族的统治。他们用月饼来传递密信。掰开月饼就可以找到里面的密信，起义军通过这种方式成功的发动了起义，赶走了元朝的统治者。这场起义发生在八月十五之时，于是中秋节吃月饼的习俗便在民间传开来。

With the rapid development of the internet, shopping on the Internet has

become a fashion in our daily life. According to the latest data, over two

hundred million people used to buy commodities on the Internet. Some of the

students also join the group.

There are many advantages about shopping on the Internet. Just by a click

of the mouse, you can buy whatever you like without going outdoors. You don’t

need to worry about being trapped in the crowed people and cars, or wasting too

much time on walking. When shopping on line, you can choose from more varieties

of goods, whose price are generally lower.

Every coin has two sides. Its disadvantages are obvious, too. On one hand,

it’s very easy for you to buy goods different from the pictures you see on the

internet，which is quite disappointed. On the other hand, shopping on the

Internet may cause people to buy commodities that are not badly needed. It’s a

waste of money.

After all, I really enjoy shopping on the Internet.

With the development of todays technology, education becomes more

important than before because people need to learn more to adapt the

society.Education enables people to understand the world better and have a good

job in the futrue.Moreover ,it also hao an impact on peoples behavior.

First of all, education improves peoples learning ability that makes them

know more about the world.Most things taught in schools are the basic skills or

means to further understsnding of our society .Only by learning these,can human

have an opportunity to study more and know more about the society .Secondly,

opportunities are often given to someone who is good educated .Employers tend to

believe that people have high education are intelligent and they can manage

their jod and adapt the working environment quickly.That is why the educated

people always get a good job. Thirdly, the more people learn the more modest and

polite they act.Learned people think that they are not good enough ,so they show

a big patience to learn from everything .They often try to figure out the

solution of problems by things they meet or learn.

In sum,education can turn people out with better learning skills,job

offering and good behavior,so I think education is important to people to

fulfill their goals and live a easy life .

Today, we have a health class. The main content is the harm of haze.

We watched a movie called "the harm of haze", which mainly explained how

terrible haze is.

Haze passed through our bodies, just like games. It comes to the blood

vessel first, let the partners block the blood vessel together, so our blood

pressure will rise; it also has a partner who is less than 0.5cm and has a knife

in both hands, and can directly pass through the blood vessel; it comes to the

internal organs, which are like a tree, and there is white fat like a giant,

which can directly eat the dirty things. However, we have iron ore in our body.

If we eat too much white fat, we will die. This is a blood station! So the

resistance of man has decreased. Its finally at the center - the heart, because

we just blocked your blood vessels, so your heart will cause myocardial

ischemia. "Tremble! Human beings! Im in every breath of yours, "cried haze.

Haze has a great influence on us. With haze, we cant play in the

playground, cant have physical education class, and we need to wear a little

annoying mask. Therefore, we should protect the environment and nature. As long

as you start little by little, you will be able to achieve the results you

want.

As is known to all food is a priority for the common people. Recently

however reports about food problems have often been seen in the newspapers

showing that people have always been concerned about what they eat every day.

The reason for this problem is that some of the food producers are too fond of

making money leading to the result that they use whatever will make the food

look good or taste better without considering the bad consequences. This is not

normal because people just cannot live without eating anything.

So we should take all the measures necessary to forbid the food producers

to make food that is not safe enough. Laws should be strengthened and the

government should have more control over these producers. Only when people are

no longer worried about whether their food is safe or not can they enjoy a

better life.

There is an old saying goes that failure is the mother of success. Everyone

confronts with failures even those famous and successful figures. Some people

say that failure lashes them to work harder. Some think that failures are so

depressing and we should not to make any failures. For me, I cherish failures

very much for we can realize our shortcomings from them.

First of all, we can learn from failure and get more experience. It is

indeed so disappointed when we confront with failure. However, we can always get

some experience from failures and makes us understand our weak point. If we can

learn from failure, then we will avoid such problem in the coming days.

Secondly, the more failures, the more successful we will be. As the old

saying goes that failure is the mother of success. The more failure we make, the

more successful we will be. If we make many mistakes, then we will learn a lot

from them and will do better when we meet the same kind of problems. This means

we will obtain great success if we meet more failures.

All in all, failure is a bad thing for people, but it is a good chance for

us to learn more from it and become successful in the future.

ncreased stress results in increased productivity--up to a point. However,

this level differs for each of us. Its very much like the stress on a violin

string. Not enough produces a dull. harsh sound. Too much makes sharp, annoying

noir, or causes the string to snap. However, just the right degree can create

magnificent tones. Similarly, we all need to find the proper level of stress

that promotes optimal performance, and enables us to make harmonious music. Good

health is more than just the absence of illness. Rather, it is a very robust

state of physical and emotional well being that acknowledges the importance and

inseparability of mind/body relationships. In the next program. I hope you will

join me in the pursuit of learning how to exploit stress, so that it can work

for you. and make you more productive, rather than self-destructive.

Nowadays it is common to encounter a scene when people want to see things

happen but can‘t make things happen for various reasons. The most important

reason is that they just refuse to create and innovate. With the accelerated

pace of our society,more and more people recognize the importance of creation

that is bound to make a difference in social productivity.

As far as I am concerned,we should all have the notion of being the

participants of supporting creation. First of all,creation is the most vital

factor to improve the inner competitiveness of our nation. For another,it is

certain that creation is so essential that enables many people to find their

positions in the company and careers in their lives.

Measures are also needed to encourage creation . First and foremost,the

government should establish certain rules to sweep up the obstacles of

invention. Some people have already complained much about complicated procedure

of patent applications or high fees to do experiments of inventions.

Additionally,high schools and universities can provide students with

scholarships or overseas learning opportunities,which will stimulate more

youngsters to join the group of invention and innovation.

The way people hold the belief that a fun-filled， pain-free lifestyle

equals happiness actually reduces their chances of ever obtaining real

happiness. If fun and pleasure are equal to happiness，then pain must be equal to

unhappiness. But in fact，the opposite is true： more often than not things that

lead to happiness contain some pain.

As a result，many people avoid the very attempts that are the source of true

happiness.They fear the pain inevitably (不可避免地) brought by such things as

marriage，raising children，professional achievement， religious commitment，

self-improvement.

Ask a bachelor why he resists marriage even though he finds dating to be

less and less satisfying. If he is honest，he will tell you that he is afraid of

making a commitment，for commitment is in fact quite painful. The single life is

filled with fun， adventure and excitement.Marriage has such moments，but they are

not its most distinguishing features.

Couples，with infant children， are lucky to get a whole nights sleep of a

three-day vacation. We dont know any parent who would choose the word fun to

describe raising children. But couples that decide not to have children ever

know the joys of watching a child grow up or playing with a grandchild.

Understanding and accepting that true happiness has nothing to do with fun

is one of the most liberating realizations. It liberates time： now we can devote

more hours to activities that can really increase our happiness. It liberates

money：buying that new car or those fancy clothes to increase our happiness now

seems pointless. And it liberates us from envy：we now understand that all those

who always have so much fun actually may not be happy at all.

Before I went to middle school, I lived with my grandparents. At that time,

I stayed in the country, which was the most beautiful place for me. Early in the

morning, I walked along the country road, appreciating the fresh air. We raised

a little dog. He was my best friend, and he accompanied me all the time. No

matter what I did and where I went, the little dog was with me and I loved him

so much. Sometimes I would pick up the fruit in the garden, sometimes I would

catch the fish in the clear river. It was such a happy childhood for me that I

will never forget.

keeps on learning.

In spare time, I like reading books, surfing on the Internet, listening to

music like, classic, or light music, because they can make me feel relaxed.

Nobody could keep on working efficiently, therefore proper amusement is a must.

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