4．　　It was Saturday again. Lily and Lucy disliked Saturdays. That was another thing the twins had in common. They shared the same clothes and tied their hair in the same manner. In fact, it was hard for their classmates and teachers to tell them apart sometimes.
　　Unlike their classmates, they had to get up early at seven every Saturday to prepare for their lessons. Lily had to attend the art lesson and Lucy had to attend her ballet lesson. "How I wish I could do something different today," said the twins with one voice. All at once, an idea came to Lily and Lucy at the same time. "Do you have the same idea as me?" they asked each other and laughed. It seemed like a wonderful plan to them. After giving each other a description of their own friends, Lily put on Lucy's ballet dress while Lucy put Lily's brushes and paints into her bag. Then they left for their classes.
　　When the art lesson started, Lucy couldn't understand the art teacher. Unlike Lily, Lucy was poor at drawing. When the art lesson finally ended, Lucy didn't dare to hand in her work.
　　Meanwhile, Lily was struggling in the ballet class as well. As she had no idea about the dance steps, she had to follow her classmates blindly. As a result, she kept knocking into them . Their ballet teacher became impatient with her, "Lucy, you should remember the basic steps. You can't depend on copying what others are doing. "
　　When Lily and Lucy arrived home, they were tired out. They decided that they would never try to be someone else that they were not.

5．　　One cannot discuss Chinese music without mentioning the guqin, one of the four arts — along with game of go, calligraphy (书法) and painting. It first appeared over 3, 000 years ago and stands for China's solo musical instrument tradition.
　　At first, the guqin had only five strings (弓玄), meaning the five elements (元素) of metal, wood, water, fire and earth. Later, in Zhou Dynasty, King Wen of Zhou added a sixth string for his son. King Wu of Zhou, added a seventh string to encourage his army to fight with the Shang.
　　 Ambience was important in playing the guqin. Usually, it was practiced in a quiet setting and never for public performance. Ancient artists enjoyed performing by a stream in the mountains. The sound of the guqin mixed with the echoes (回音) from the mountains, until the musician felt he was at one with nature. Playing it in snow was also an enjoyable activity for ancient artists, who believed the instrument was the purest of its kind in the world. Also, a night with moonlight was considered wonderful for playing the guqin. Wang Wei (701—761), a highly talented man of the Tang Dynasty, liked playing it in a bamboo forest on nights with moonlight most.
　　Guqin pieces are usually three to eight minutes long, with the longest being Guangling Verse, which is 22 minutes long. Other famous pieces include Plum Blossoms in Three Movements, Wild Geese Landing on the Sandbank and Eighteen Songs of a Nomad Flute.
　　Nowadays, there are fewer than one thousand well-trained guqin players and perhaps no more than fifty living masters. The original number of several thousand pieces has greatly reduced to only one hundred works by today. The guqin and its music was added to the list of the Intangible Cultural Heritage of Humanity (人类非物质文化遗产) in 2003.
