Now the earth is in bad condition。 For example， in some places， the air and

water pollution is so serious that it causes many deaths。 At the same time， many

animals and plants are in danger because of the destruction of their

habitats。

Luckily， we human beings have realized the problem。 On April 22nd， millions

of people across the world do something good for the earth。 Some clean up

beaches and water， some pick up rubbish， others give speeches to call on more

people to take action。 But can we save the earth only by one day’s work? The

future of our planet depends on our efforts。 What we should do is to make every

day Earth Day。 Only by taking good care of it every day can we hope to live in

harmony with nature。

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.

I have studied in my middle school for three years.My life in middle school

is rich and I have learned a lot. I get knowledge from text books as well as

from extra curricular activities. I studied hard in the past three years so that

I got perfect scores. But, I also attach importance to other aspects, such as

making friends, hobbies, health and sports. I build good relationships with my

classmates. They become an important part of my life.I like to chat with them

after class that makes me relax and comfortable. My hobby is swimming. Every

Sunday morning, I go to swim with my friends or my father. When I have fun, I

build a healthy body. Its so great to me. In one word, my life in middle is

colorful and unforgettable.

In our daily life, we can learn something from some cases. However, from my

point of view, I think that it is essential for us to know ourselves in a right

way. People who have a full awareness of the importance to improve themselves

will discover themselves continuously. Therefore, we can say that if we want to

change ourselves, we must bravely reveal ourselves.

Every coin has two sides, and we are no exception. When we experience some

situations, we will find that there are many advantages of us. Thus, we can have

a huge sense of satisfaction. We may have a little pride, because we are happy

that we can make good use of our advantages to solve more difficult problems in

the future. However, at the same time, we also can realize that there are still

some disadvantages of us. These disadvantages will bring us different

influences. I’d like to point out that people who can bravely accept and remove

their disadvantages will gain a bright future. On the contrary, people who

choose escape or ignorance their disadvantages will indulge themselves, and they

no further progress.

Don’t indulge yourself. If we indulge ourselves, we will meet more terrible

suffering in our later life. I know that when we find our weakness, we may say

that I will never do that again, and regret doing so meaningless thing. I am

such a fool. But when we meet similar situations next time, we will still tell

ourselves that it doesn’t matter that I do it again. Then we will indulge

ourselves to expand our disadvantages. It shows that some people who have no own

principle will fail to realize their promises. When we can overcome our

laziness, we will understand that solving some problems may be not so difficult.

Therefore, we should try our best to control ourselves to pursue higher

development.

There are no any excuses to indulge yourself. We should tell ourselves that

we are capable to overcome our weakness, though it needs much time. However, if

we succeed once, then we will be successful again. Last, we don’t indulge

ourselves. We will become more complete.

Everyone can take actions to improve themselves. Don’t indulge yourself. If

you succeed, you will acquire a huge wealth, and your life will become more

brilliant.

Today, as the development of the medical, people can slow down their aging.

As for the celebrities, they use the developed technology to keep young, seeing

their unchangeable faces in the screen for so many years, the audience also want

to imitate the celebrity, they believe that by using the developed technology,

they can keep young all the time. While in my opinion, the way to keep young is

to hold a young heart, some people look young outside, but in their hearts, they

are old enough and refuse to keep pace with the time. While for another group,

even they have wrinkles, they are curious about all the things and are willing

to change. My grandpa is old, but he knows all the fashionable things, sometimes

I have to ask him for the new things. The young heart is the way to keep young

forever.

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。

所以中国新年就要到了。

The Dragon Boat Festival is one of the most popular traditional festivals

celebrated in China, which is on the fifth of the fifth lunar month, also known

as Duanwu Festival. It’s said that it is to commemorate the death of a Chinese

patriotic poet, Qu Yuan, who was snared by corrupt officials in ancient China

and finally committed suicide by drowning himself in the Miluo River to protest

against them.

The traditions and customs held on this festival differ from place to

place, but there are some common in them. First, the most famous and great

tradition is holding Dragon Boat races, which are held by fishermen’s attempt to

protect Qu Yuan’s body against attacking by fishes and other animals in the

river by beating drums and row the dragon shaped boat. Nowadays dragon boat

races have been an annual popular sport activity among people. In addition,

making and eating Zongzi—a dumpling made of glutinous rice and wrapped in bamboo

or reed leaves—is also a popular custom during this day. It can be made by many

kinds of stuffing. What’s more, hanging herbs on the front door, drinking

realgar wine and pasting up picture of Zhongkui—a mythic guardian figure in

ancient china—are also popular during the festival, which are mean to protect

people from evil and disease.

These customs and traditions have been changed a little in recent years,

but they still make contribution to the spread and inheritance of Chinese

culture.

Last week, I saw a very impressive documentary about panda. A professor

studied panda in the early 1980s went to the wild life and kept trace of wild

giant panda for many years. As a result, he found that it was human being that

made these lovely animals die out. At that time, many people believed that giant

panda became less because of the low rate of newborn babies. But it was not

true. People cut trees for making profit at that time. Panda lose homeland and

they lacked of food. Thanks to these valuable data, the government took the

policy to protect the animals. So today, the number of giant panda is

increasing. People realize the importance of protecting the environment and it

is the best way to protect wild animals, they are the indispensable part of the

nature.

Day, night, and finally ushered in the long-awaited summer vacation. In

these two months, can"t play games every day! Besides, even if I think so, mom

and dad are certainly can"t promise. Only done to make them more satisfied, my

freedom is a bit more, this summer vacation will have a more pleasant. Combined

with the requirements of the teacher and I wish mom and dad, have a preliminary

arrangement.

A little monkey picks up a pumpkin and wants to take it home.But the pumpkin is toobig.The monkey cant take it home.

Suddenly he sees a panda riding a bike towards him. He watches the bike. "l have a good idea. I can roll the pumpkin. It likes a wheel."

So he rolls the pumpkin to his home. When his mother sees the big pumpkin, she is surprised and says, "How can you carry it home?" The little monkey answers proudly, "l cant lift it, but l can roll it." His mother smiles and says, " What a clever boy!"

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.

Because of the high developing speed of the world, pressure has become a

serious problem in nowadays. As our students, we also have to face with much

pressure, such as the study pressure, exam pressure,relationship pressure and so

on. But how can we cope with pressure? This is the most important.

Firstly, we should face the pressure appropriately. Pressure is inevitable

in our daily life, so we cant be afraid of them and try our best to cope with

them. Secondly, tell our pressure to others. Talking is a very effective way to

ease pressure, and during the talking, we may get some suggestions and

solutions. Finally, trust ourselves. We should believe ourselves that we can

deal with any troubles by ourselves or by others help.

Nowadays, with the development of technology, the market competition is

fierce and people feel great pressure. In order to improve the working

efficiency, they force themselves to work overtime. However, they are not

machine and need to slow down life pace, or they will break down sooner or

later.

We cant slow down the working hour, but we can control our private time. A

lot of young people mix with working time and private time, so they cant enjoy

their life and feel depressed all the time. The smart person will find the

balance. They will put aside the working stuff when the clock tells them that it

is time to be off work and find the way to release their pressure, such as

KTV.

Spending the time with friends and families is always a good way to enjoy

our time. No matter what kind of difficulties we face, when we recall of these

happy moments, we will have motivation to move on. We cant choose everything we

want, but we can adjust ourselves to the environment and keep the good mood.

Once life pace slows down, we control our life.

Communication is the activity of conveying information through the exchange

of thought, messages, or information. There are many communicating methods, such

as speech, visuals, signals, writing or body languages.

It plays an important role in social lives of human beings, which some

people consider that it’s the basic of human existence.

On the one hand, it’s the communication that spreads information, making us

know the news although it’s far from us. By communicating with others, people

send and get information that helps us know about our surroundings. We all know

that information is extremely important in our lives. On the other hand,

communication builds personal relationship, which connects different people

together. We live in the same society which makes personal relationship

essential in lives. Only with communication can we build and keep good personal

relationships with others. In addition, communication can eliminate

misunderstandings and promote emotions. When we have misunderstandings with

others, timely communicating is the only effective way to solve it.

In short, communication is essential to all people that everyone should

realize that. Therefore, we should learn how to communicate with other

effectively.

When I go to high school, our school has the rule to ask students to live

in the dormitory. Most students live with their parents before, so we all feel

excited and afraid of the group life. Luckily, I have three nice roommates. Soon

we become close friends. Living with others, we learn to do the house work, such

as everyone needs take turn to clean the floor, when we have something good to

eat, we will share with each other. The group life makes us have less private

space, but we enjoy the moment when we have the little talk before sleep, the

secrets that we dont want our parents know can talk to these girls. Whats

more, I become much independent. I learn to take care of myself and have really

grown up.

Last week, our school held an activity to the nursing house to visit the

old people. I was so excited to be a volunteer, because it was my first time to

join such big activity. When we got there, the old people were so happy to see

us. They smiled all the time. We brought them some fruit and presents, and they

were so moved. When we chatted face in face, they talked about the old times and

the happiness they had. I thought about my grandparents, who lived in the

hometown. I should spend more time with them. Being a volunteer is such a

precious experience for me.

Volunteers are the pulse of the city and the beautiful scenery of the city.

They are composed of a group of enthusiastic young people who love public

welfare and support the public welfare undertakings of the society.

In the volunteer organization, every volunteer is equal, everyone is equal

in personality and status, everyone has come together for a common goal, it can

be said that they are the most intimate brothers and sisters without blood!

A team is composed of people, and there must be a certain division of labor

according to peoples abilities. Some people are suitable for leadership, some

people are suitable for publicity, and some people are happy to be ordinary

volunteers working on the front line.

The so-called people do their best.

Only make the best use of it! Only such a group can flourish and thrive! If

you just divide the volunteers into three, six or nine classes based on their

abilities, identities, and statuses, it will hurt not only a persons emotional

problems, but also the longevity. , the affinity and cohesion of the team will

be greatly reduced! If the composition of the volunteers are all dignitaries,

then the transparency of the volunteers will have to be doubted by the

world.

Although it is said that if you are poor, you will be alone, and if you are

good, you will help the world, but it does not rule out that there will be some

people who are not rich and not very capable, but are willing to do their best

to join this organization. I think we should also. Accept them with a tolerant

heart, because our organization is voluntary, fair, and equal!

志愿者是城市跳动的脉搏，是都市亮丽的风景，由一群热爱公益的热血青年组成，撑起了社会的公益事业。

在志愿者组织中，每一位志愿者都是平等的，大家在人格上，地位上都是平等的，大家为了一个共同的目标走到了一起，可以说是最为亲密的，没有血缘的兄妹!

一个团队，由人组成，根据人的能力必然有了一定的.分工，有的人适合做领导，有的人适合做宣传，而有的人乐于做一个普通的义工工作在第一线。

所谓人尽其才。

才尽其用!这样的团体才能蓬勃发展，蒸蒸日上!若硬是把志愿者依据能力、身份、地位的不同，分出个三六九等，所伤及的怕不只是一个人的情感问题，天长日久，团队的亲和力、凝聚力怕是要大打折扣!倘若志愿者的组成都是些达官显贵，那么志愿者的透明程度，就不得不让世人怀疑了。

虽说有穷则独善其身，达则兼济天下一说，可也并不排除会有一些并不富裕，能力不是很强，却愿意尽自己绵薄之力的人愿意加入这个组织，我想我们也要以一个宽容的心来接纳他们，因为我们的组织是宗旨是志愿、公平、平等!

Seasons have colors. What are the four seasons colors like?

Spring is green. When spring comes, trees begin to bud and grass begin to

grow. It is really a green world, and it is also the color of hope.What about

summer? When I look at flowers of almost all kinds in blossom, I know that the

color of summer is red.Compared with summer, autumn is totally different color,

especially in the north of our country. The rice in the fields and fruits on the

branches are the signals of autumn. It is the color filled with ripeness. Gold

is the symbol of harvest.Winter is the world of snow. Therefore, white is the

color of winter.

Seasons have colors and the changing of the four seasons makes the land

colorful and energetic.

When I watch the TV series, there always present the rich familys life,

but I dont feel envious about the rich life. It is obvious that though these

people live the better life, the cost is that their parents spend less time to

play with them. The time to stay with our parents is really important, while the

rich parents have much work to do, so they dont have much private hours. I was

born in an ordinary family. My parents will never miss the moment when I need

them. I am so thankful to life, because I have my parents love. Whats more, I

have made many good friends. We share our interest and have a lot in common.
