My name is Wang Xiaochuan. I’m eleven. I live in a small house in Taicang.

I study at Zhu Diwen Primary School. I have seven lessons every day. I study

Chinese, Maths, English, PE, Science, Art, Music, Social Science and Computer

Studies. I like Science, It’s interesting. I don′t like Art, I can’t draw very

well. I usually play games with my good friends, Sun Zhe and Gu Xu ,on Sundays.

I like swimming, playing badminton and playing table tennis.I like eating fruit,

just like strawberries, watermelons and peaches.

Just in the month of this month, xu wenxu, a farmer of the village of jiaxi, the tujia miao autonomous county in chongqing, was busy. In order to prepare for this New Years eve dinner, some of the essential traditional entrees are not available for the first ten days and a half months. The most important of these are "dunking" and "pepper irrigation". Xu wenxu said, "the cut meat" seems simple, but to be really fat and not greasy, soft and smooth mouth, is to take a hard time. "Irrigation HaiJiao" is to mix in the glutinous rice noodles HaiJiao ingredients after fill in the empty one by one, and then into a pickle jar sealed half a month, in the New Years eve, take out a Fried oil will be ready to serve.

Tujia attaches importance to the two dish, because before all the year round on a few back to meat rare, glutinous rice is also a rare thing, so every family take this chance to show your skills as a family reunion dinner two dish, is also the family in order to reward hard work for a year.

Surprisingly, the kelp was once the main dish of the tujia family reunion dinner. Because the former tujia region to eat salt and water is difficult, medical conditions are also poor, often people have a large neck disease due to iodine deficiency. In order to provide the family with iodine, the family members of the family in the lunar New Year dinner together with a kelp, in order to replenish the iodine needed by the human body. Under the conditions at that time, the kelp was a "delicacies" to the family, and it was impossible to eat them regularly, so it became a good dish for the annual dinner. Today, the kelp has long been out of the stage.

After the family had eaten the New Years eve dinner, each family would have a log of firewood, and everyone would sit around and listen to the old man telling the story. The old man was waiting for the first day, and he was called "the ridge of the field" to express his love for the field.

Ethnic Korean: "wine" and "degu" occupy a special place

The yanbian Korean autonomous prefecture of jilin province is the main settlement area of Korean nationality in China, and the Spring Festival is also the traditional and most important festival of Korean nationality. The Korean lunar New Year meal has its own traditional food and features.

The Korean people have a lot of food, large and small plates, or even hundreds of dishes. The special place is the old wine and degu.

On the eve of the Spring Festival, reporters in the villages of yanbian Korean autonomous prefecture saw that many ethnic Korean villagers were brewing "old wine". The Korean people have the custom of drinking "wine" at the feast. This wine is often brewed before the "year of the year". The festival is equivalent to the Spring Festival of the han nationality, and the "year old wine" is mainly made of rice, which is a kind of medicinal liquor. During the Spring Festival, they drink and entertain themselves. They believe that drinking this wine can ward off evil spirits and long life.

"Is" is a kind of bread, soup is to big rice noodle and steamed, pounded into big stick, and then rub into oval round bar, sliced, pour into chickens, pheasants, beef soup pot, to eat again when put some sesame oil and sesame oil and seaweed, taste delicious.

On the thirtieth day, Korean women wear beautiful national costumes. Most families start making cakes in the early morning. Despite the fact that there are now machines for making cakes, they still prefer to use the hammer for themselves, because they still taste different.

On New Years eve, a family reunion dinner is a very happy time, and the whole family will stay up all night. Unlike the han Chinese, the Korean family will dance and dance with the old Korean gayqin and pipe music to welcome the New Year.

刚进腊月，重庆市酉阳土家族苗族自治县板溪乡红杏村农民许文旭家就忙开了。为了准备好这顿年夜饭，一些必不可少的传统主菜不提前十天半月准备是不行的。其中最主要的当数“扣肉”和“灌海椒”。许文旭说，“扣肉”看似简单，但要做到真正肥而不腻、嫩滑爽口，是要下一番工夫的。“灌海椒”则是把糯米面拌上作料后填入一个个掏空的海椒中，然后放入咸菜罐子里封存半个月，到了除夕，拿出来用油一炸就可以上桌了。

土家人之所以重视这两道菜，是因为以前一年到头难得吃上几回肉，糯米也是稀罕东西，因此家家都把这两道菜当作年夜饭展示手艺的机会，同时也是为了犒劳辛劳了一年的家人。

令人意外的是，海带还曾一度成为土家年夜饭的主菜。因为以前土家族聚集地区吃盐巴都困难，医疗条件也差，经常有人因缺碘患上大脖子病。为了给家人补碘，土家人就在年夜饭上一道海带，以补充人体所需的碘。在当时的条件下，海带对土家人来说，真可谓 “山珍海味”，经常吃根本不可能，因此成了年夜饭上的一道好菜。如今，海带早已退出年夜饭的“舞台”。

土家人吃过年夜饭后，各家都会燃起一根木柴，大家围坐聆听老人讲故事，守岁到天亮，名叫“守田埂”，以表达对田地的热爱。

朝鲜族：“岁酒”和“德固”占据特殊位置

吉林省延边朝鲜族自治州是我国朝鲜族主要聚居地区，春节也是朝鲜族的传统的和最重要的节日。朝鲜族的年夜饭有着自己传统的食品和特色。

朝鲜族的年夜饭丰常丰富，大大小小的盘子七八十个，有的人家甚至达上百个。其中占特殊位置的是‘岁酒’和‘德固’二种。

春节前夕，记者在延边朝鲜族自治州的各乡村看到，很多朝鲜族村民都在酿造“岁酒”。朝鲜族在年夜饭有喝“岁酒”的习俗。这种酒多在过“岁首节”前酿造。岁首节相当于汉族的春节，“岁酒”以大米为主料，配以多味中药材，是一种药酒。用于春节期间自饮和待客，他们认为饮用此酒可以避邪、长寿。

“德固”是一种汤饼，就是将大米面和好蒸熟后，捣成大粘团，再搓成椭圆形圆条，切成薄片，倒入鸡、野鸡、牛肉汤锅中，吃时再放些麻油或香油以及紫菜，味美可口。

在年三十那天，朝鲜族妇女都要穿上漂亮的民族盛装。大多数家庭从一大早就开始做打糕。尽管现在有卖做打糕的机器，但他们还是喜欢用打糕槌自己动手做，因为感觉味道还是不一样。

除夕夜一家都围在一起吃年夜饭，是非常幸福的时刻，全家都会守岁通宵达旦。与汉族不同的是，朝鲜族大年夜这顿饭会载歌载舞，伴着朝鲜族古老的伽耶琴和筒箫乐曲迎接新年的到来。

People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

My preference depends on the purpose of the travel. On a summer vacation I travel to refresh myself and to see the countryside. When I use my feet and walk on a grass covered path along a river or among the hills I feel detached from the noise of the city and closer to the nature. And when I travel on foot I get more freedom. I can plan my own schedule. I can choose my own route. I can stop where I like. And I can see things and people that I might miss if I travel on a train or on a bus. net

When faster and more convenient ways for travel are becoming available, I still favor using my own feet. I get much pleasure from it. People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

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.
