As is known to all of us, Beijing Opera is one of the most important opera styles in China. It is an art on the stage which has about 200 years' history. It is not only a treasure of the Chinese nation but also a cultural symbol of China. Similar to western operas, Beijing Opera is a combination of singing, dancing, martial arts, music and literature, so it is also called the "Oriental (东方的) Opera" by western people.

    Beijing Opera uses special imagery in creating the characters. All roles are divided according to sex, personality, age and profession and social status. Hangdang is the general term for role in Beijing Opera. There are four types of roles in Beijing Opera today. They are sheng, dan, jing and chou. The sheng is the male protagonist (主角), the dan the female protagonist, the jing (painted face) a male supporting role with a different characteristics, and chou (clown) a comic or negative figure. Each kind of role has their own face-painting and dressing to indicate their identities.

    The Opera's performance requires not only the gentle voice but also the proficiency (熟练) of martial actions. A successful opera actor must suffer from the tough practicing period. In the old time, the children of poor families were sent to the opera group in order to earn a living. While now, the real opera artists are well respected by opera lovers.

    Mei Lanfang, one of the most remarkable performing artists in Beijing Opera, was born in Beijing into a poor family. His life was bitter and he had no opportunity to go to school, so he went to the troupe (戏班子) when he was 8 years old to learn Beijing Opera. Mr. Mei was on the stage when he was 11 years old to perform the plays of Beijing Opera. He has been an opera actor for more than 50 years, performing hundreds of traditional plays and over 30 modern plays. He portrayed many bright and lifelike female figures on the stage and became the model in Chinese Beijing Opera and even within the entire artistic circle.

I wake up at six in the morning. Dad is putting the cows and sheep onto the trucks. Mom is putting my favorite milk food and some dried meat (肉干) in a bag. We will start driving to another past ure (牧场). We won't forget to take our yurt(毡房) with us!

 My family moves like this four times every year. It's a tradition (传统) of the Kazak people in Altay, Xinjiang. We have about 100 sheep and 40 cows. We move to different places as the seasons change. So, our animals can always have fresh grass to eat.

 Kazak people have been traveling this way for thousands of years. In the past, it took people about ten days to get from one place to another. If it rained or snowed, traveling was even harder. Luckily, now we have trucks. It only takes us five hours on the road! And as we move from place to place, our lives keep getting better and better.

Can a green machine help the world's poorest kids learn better? You must feel curious (好奇的) to know 1 the green machine is. Now here are some things 2 the green machine. Nicholas Negroponte 3 his team of scientists have invented a new type of computer. As a result, many poor kids will have their own laptop computers.

Negroponte works at a university. He started 4 organization called One Laptop Per Child (OLPC). The people at OLPC don't work for money. They work 5 children learn. OLPC makes computers that don't cost a lot. Then the machines 6 by them to governments of poor countries. The governments then give the computers to kids for free. The low price means millions of poor kids 7 receive a computer. This is very good for 8 .

Maybe, only a computer can open a window for them to see a 9 world than before. OLPC plans to give out over ten million computers in the future. Kids in Thailand, Nigeria, Brazil, and Argentina 10 most of them.

There are so many languages that you can't hope to learn them all, but there's one language which you can use to communicate with everyone: your smile.

 Smiling can show people that you' re friendly. And we have more than fifty different kinds of smiles for different situations. When something is funny, we usually smile with an open mouth. If we are happy, our eyes become smaller when we smile, but if the skin around our eyes doesn't move, our smile is not real. If we are proud of something, we keep our lips together.'

 But what if you are in a bad mood? It's hard to be happy all the time. Some people try to cheer themselves up by watching funny films. Others like dancing to their favorite songs or eatıng sweet food. Others do sports every day to put themselves in a good mood. But there's another very easy way to feel happier: smile. When you smile, your body starts producing the things which are called endorphins(内啡肽 ). These endorphins send a message to your brain that you, are happy. And there's something more important. When you smile at someone, they often smile back at you. This action produces endorphins in their, bodies and they feel happier too. A part of their brain remembers you as a person who makes them happy. You' re halfway to having a new friend. And that's something you can truly smile about.
