difficulties now and then. The one who runs away from the test may be a loser

When it comes, we should not run away. Regardless of the result, we will gain

precious experience and become stronger. My parents stand by my side all the

time, and they give me the confidence to fight. I am so thankful for them. They

give me the confidence, which is the very important thing in my life.

theirselves.What is the most common reflection of this phenomenon is

dishonesty,which is now seriously influencing relationship between people.

Being dishonest can do harm not only to others but also to

ourselves,thus,we must get aware of the importance of boycoting it.Take the case

of the Sanlu powder for example.After drinking Sanlu fake powder,lots of babies

got sick and had big heads,nevertheless,their bodies still thin.People hateful

too much,the Sanlu corporation expectedly get punished and never have choice to

make up their faults.

When it comes to the significances of being honest,I consider,we will make

good relationship bewteen others,such as in the school ,in the busineand in the

society.Furthermore,only if we are honest to others can others become friendly

to us.Therefore,cultivate a virtue of honesty and we will get better.

I’m neither interested in sports nor good at it. But except swimming. I can

swim since I was a baby. My mother tells me that she let me swim in the water

with a life-buoy when I was 20 days old. And then I can swim gradually. When I

grow up, I like swimming very much. I swim all the year round. Swimming in

summer makes me feel comfortable to lower my temperature. While winter swimming

makes me feel excited and achievability. In general, swimming keeps me fit in

both physical and mental. Whenever I feel upset, I would go swimming and then I

would be full of energy and feel relax. Besides I believe it is due to swimming

that I’m so thin. Who wants to lose weight, join me. We can make more friends in

swimming. Oh, I couldn’t wait to swim now. But it is ten o’clock in the evening.

I have to go to sleep. Good night everyone.

My grandparents believed you were either honest or you werent. There was

no in between. They had a simple motto hanging on their living-room wall: "Life

is like a field of newly fallen snow; where I choose to walk every step will

show. "They didnt have to talk about it--they demonstratedthe motto by the way

they lived. They understood instinctively that integrity means having a personal

standard of morality and ethics that does not sell out to expediency and that is

not relative to the situation at hand. Integrity is an inner standard for

judging your behavior.Unfortunately, integrity is in short supply today--and

getting scarcer. But it is the real bottom line in every area of society.And it

is something we must demand of ourselves.

A good test for this value is to look at what I call the Integrity Trial,

which consists of three key principles: Stand firmly for your convictions in the

face of personal pressure.

When you know youre right, you cant back down. Always give others credit

that is rightfully theirs. Dont be afraid of those who might have a better idea

or who might even be smarter than you are. Be honest and open about who you

really are. People who lack genuine core values rely on external factors--their

looks or status---in order to feel good about themselves. Inevitably they will

do everything they can to preserve this facade,but they will do very little to

develop their inner value and personal growth.

So be yourself. Dont engage in a personal cover-up of areas that are

unpleasing in your life. When its tough, do it tough. In other words, face

reality and be adult in your responses to lifes challenges.

Self-respect and a clear conscience are powerful components of integrity

and are the basis for enriching your relationships with others.

Integrity means you do what you do because its right and not just

fashionable or politically correct. A life of principle, of not succumbing to

the seductive sirens of an easy morality,will always win the day. My

grandparents taught me that.

Its September. Autumn is coming. But where is autumn? I am told that the

sky looks higher with few clouds in autumn. I raise my head and look at the sky.

It makes no difference with the sky in summer. And trees around are still green.

Then I come to the fields. I find the corn in the ear. Apple trees nearby are

fruiting well. The harvest season is coming. I jumped with joy. This is autumn.

I found it!

When it comes to honesty, quite a lot of people believe it is essential to

a person’s character and success.

They base their idea on the following reasons: on one hand, successful

business owes much to mutual trust; on another hand, great people in history

such as Abraham Lincoln andGeorge Washington set us good examples of being

honest, they are great because they are honest.

Their reasons run as following: to begin with, cheating on exams is

becoming more and more popular; in addition, some singers and movie stars cheat

on taxes; last but not the least, if you are not careful enough, you’ll buy some

defective goods and fake products.

It is high time we emphasized and encouraged honesty. We can take effective

measures to restore it.

For example, kids should be taught to tell truth, strict rules and

regulations should be carried out to stop cheatings on exams and taxes, etc.

Chinese New Year starts with the new moon on the first day of the new year

and ends on the the full days later. In china,people regard Spring Festival as

the most important thing.People studied and worked throughout the year.No matter

how far and how busy, they must do their best to go back home.Thats a tradition

and now becoming a habit. During this time,transport is extremely busy.Although

the way is difficult,it cant reduce the urgent feeling of going home.I cant

describe this feeling,only the people that experienced it can

understand.Actually,on one hand,people miss their family,and they need to get

comfort in the family.On the other hand,getting together is a symbol of

blessedness and auspiciousness.People in other country dont have this

consciousness that going home is necessary.For example,American could celebrate

the Christmas in everywhere they like or with anybody.This diversity is

occasioned by different culture between two countries.

On Spring festivals eve,the whole family prepare the dinner.Of

course,dumplings is essential.In the

evening,family members always sit at the television and watch Spring

Festival Gala.At 0:00,people set off firecrackers and fireworks,at the same

time,children pay New Year,s call to old people.The old people give money to the

children as a lunar new year gift.Usually,people stay up late or all night.

On lunar New Years Day, the Chinese family eat vegetarian dumplings which

imply they will plain and neat in this year. People change their new

clothes,this stands for a new beginning.Next,people visit relatives with some

gifts.The second day is son-in-laws festival,the husband and married women

visit their side of the family.In a word,Chinese attach great importance to

Spring Festival.

In my hometown, the air is polluted seriously. However, in recent years,

the pollution gets from bad to worse, because of the increasing number of

private cars. Especially during the rush hours, too many private vehicles move

slowly on narrow roads, emitting a large amount of waste gas. Moreover, the

poisonous gas sent by the nearby factories is also one of the main causes of

pollution. Therefore, it’s demanded that immediate and effective measures must

be taken to restrict private cars and public transportation must be developed to

the largest extent. Besides, we should use renewable and clean energy

recourses.

People’s whole life is not too long or too short. They have experienced

many things in their life journey, such as, success, fail, happy, sad, and

excited and so on. What about dreams? Some people think that they have so many

things to deal with in the limit time. How can they spend time for dream? It is

a waste of time. However, some people regard dreams are as important as their

life. People can’t live without dream. In my opinion, I agree with the latter

idea.

First of all, dreams provide life motivation for human beings. If a person

has a dream, he will try his best to take every chance to reach it. Even though

he will meet many difficulties on the way, even has to give up, but he will

renerve in the end. It is because he has dreams, and he has the desire to see

the day his dream come true. So no matter what obstacle he meets, he has the

motivation to overcome. This is the power of dreams.

In addition, life without dreams is meaningless. We often see that when

someone talks about his dream, his face is full of smile. It is because dreams

give him hope and fun. No matter the dream is easy to make it or not, when the

people think of it, they will have the beautiful vision to fight for. But if a

person who don’t have a dream, he would not know what he should do and can do.

His life is confused and meaningless.

In a word, dreams look like the lighthouse in the ocean. It gives people

motivation and the meaning of their journey. It is so significant that everyone

needs dreams.

Nowadays, as the development of high technology, people like to use

computer, they use computer to read the news, to play the game and so on. Now

more and more computer functions have been developed, people like to do business

on the computer, it saves people a lot of time and it is very convenient.

Shopping online is most people’s choice today, but it has disadvantages. First,

the products will be not in good quality, people can’t touch the products, they

only can see the pictures, so they can’t figure out the real products’ quality.

Second, when people pay the money online, they will have the chance to leak out

their message, their online account will be attacked by the hackers and thus to

lose the money. Of course, shopping online is more and more popular, we must

take care of personal message when shopping online.

I have learned English for many years, as I learn more knowledge about the

English, I become more and more passionate to have a look at the world. When I

was small, I knew nothing about the world, I believe the place I lived around

was the whole world, then I came to middle school, I realized the world become

more and more bigger, but how big it was, I had no idea. As I came to high

school, I learn more about the world, There are all kinds of cultures in western

countries. I am so interested in the culture, I want to go to these places and

talk to the local people. This is my dream, I believe I can realize my dream,

since the traffic is so convenient. I must study hard and earn money, so I can

make my dream come true.

I,m so glad to receive your letter, in which you wanted to know about the

Dragon Boat Festival in China.

I feel honored to tell you about it. Celebrated on May 5th in the lunar

calendar, it is a folk festival having a history of more than two thousand

years. Also, it is one of the most important festivals in China.

As for the origin of the Dragon Boat Festival, there are many beautiful

legends, of which the story about Qu Yuan is most widely accepted. Qu Yuan, a

Chinese poet who loved his country deeply, drowned himself in the Miluo River

after his country’s being defeated. To honor him, people in China hold various

activities every year, including eating zongzi and dragon boat racing.

I hope you can come to China to enjoy it for yourself.

Since the summer holiday comes, I have a lot of freeTime, as I stay at

home all the time, my mother suggests me to take a part-time job, I am so

willing to accept her idea, because I want to earn money by myself. I find a job

as waiter, I have to work early in the morning, people need to have their

breakfast, I serve them. On the job, I earn little money, but I have worked so

hard, I get to know it is not easy to earn money, so I start to feel grateful

for my parents. Now I won’t waste money, before I pay for the bill, I need to

measure them.

Behind every great achievement in anyones life lies perseverance. We see

this in every human endeavor. Outstanding sportsmen spend all their time

practising. Their endurance is beyond imagination.

The same is true of businessmen who build up fortunes. What we usually see

are their achievements, but once we go behind the scenes we will find that they

have put in a lot of continual steady efforts. We all have read of great

musicians, writers and inventors who have created or discovered breakthroughs in

human achievement. Invariably they have said that they owe all their success to

perseverance. As to college students, quite a big number of then, have become

successful language learners through perseverance, however, a certain group of

them, just stop half way and their previous efforts turn out to be

fruitless.

Of all the countless examples the saga of Colonel Saunders is perhaps one

of the most outstanding. The 65-year-old man from Kentucky had a dream to start

a chain of fried chicken restaurants all over the world. To realize his dream,

he knew that he needed a restaurant owner to go into partnership with him to

open the first restaurant and to fry chicken according to the secret recipe he

had. Colonel Saunders had knocked on 1008 doors before he finally found his

partner. It is doubtful whether many of us would have had the perseverance to

knock even a hundred doors.

From the above discussion we can draw a conclusion that success comes to

anyone who keeps working perseveringly and lack of perseverance can only result

in frustration and failure.

If a book is the sky, I was the birds fly freely in the sky; If a book is

the sea, I will be the swimming fish; If the book is the forest, I is the forest

the jubilant fawn; If the book garden, then I will be the dancing butterfly. Is

ah, gorky said: the book said that the ladder of human progress. The status of

books in peoples minds.

The classmates, dont your parents let you read, think to learn major

courses is the most important? The benefits of reading: not only can improve the

ability of project, it is a great way of reading comprehension.

Remember once, the teacher arranged a composition, only a minority of the

whole class classmate "optimal" I one of its top, one might ask: how do you only

into their "team"? What is the "secret weapon"? Let me tell you: "secret weapon"

that book! Reading is not enough light to read a few times, read read through

the book, and those who make you feel good good words we accumulation. I also

specially prepared a unaccustomed strain. You look! The "king" composition is

leisurely leisurely reading! Accumulation of his words have a Big Ben, think of

is dazzling, how could he not write good, good composition?

I often read books, the romance of The Three Kingdoms, "journey to the

west", "the Wolf dream king", "red ribbon lion king" is favored by me, such as

read book is ever new, one of the "the black swan amethyst" I have read a dozen

times.

Books are necessary in my life, also is the most gorgeous rainbow in my

life, because it brings the colorful life.

Dear Sarah,

I am terribly sorry to tell you that I am unable to attend your birthday

part next Thursday evening. That is owing to the fact that my younger brother

suddenly fell ill and was taken to a hospital this morning. I have to go there

immediately and take care of him. As told by the doctor in charge, it will take

around five days for him to recover and I have asked my boss for a leave.

I really regret that I cannot go to celebrate your birthday personally and

would miss the perfect chance of enjoying myself with all our old friends. I

have chosen a small gift for you and will send it to you tomorrow to show my

best wishes. Besides, please give my regards to our friends when you meet them

at the party.

Cordially,

Li Ming

Yesterday, my parents were not home. And I had to stay at home by myself for one day and one night. I was very happy at first, because there wouldnt be anyone criticizes my behavior. I can do whatever I want. But later I felt desperate. There was nobody cook for me, asked me to do things or criticized me. I felt empty and desperate as the house is only me. When the night fell, I was afraid. The computer games or the cartoons couldn’t attract my attention. I hate living alone.

昨天，我的父母不在家。我得自己一个人呆上一天一夜。我一开始很开心，因为没人会批评我的行为了。我可以做任何我想做的事。但后来我感到很郁闷。没人给我做饭，没人叫我做事情也没有人批评我。整个房子只有我一个人，我感到很空虚和郁闷。当夜幕降临的时候，我就开始很害怕了。电脑游戏或动画片都无法吸引我的注意。我讨厌一个人生活。

The main function of public libraries is to provide books for people to

read.In a library,there are books on different subjects,such as Chinese

history,fine art,science,English literature,and so on.There are also works fo

fiction.

The public libraries are crowded with people on weekdays as well as Sundays

because many people,especially students who want to consult reference books for

their school work,know that they could at least learn something there.

Besides reading in the library,we can also borrow books with library

cards.But books on loan had to be returned within a couple of weeks.As far as I

know the number of people who borrow books from public libraries is increasing

year after year.

I go to the City Hall library twice a month to read.
