      Each Tuesday afternoon, after the bell rings for the fourth period, Liu becomes a fashion designer. At the

same time, the rest of the students at the High School Attached to Yunnan Normal University in Kunming are

also having classes a little bit different from the usual ones. Some students dance, others create robots, and

still others review films. These are just a few of the other 27 elective (选修的) courses besides Liu's sewing

class that the school began to offer last month.

      "The fashion design class has become the bright point of my week. I learn how to choose colors and

fabrics (织物) as well as sewing and sketching (素描) skills. It's all helping me to realize the dream of

becoming a fashion designer I've had since I was a little girl," Liu said.

      Design is Liu's favorite, but for other students the electives are interesting lessons which relieve (舒缓)

the pressures of schoolwork. Some students, for example, are learning how to play bridge. Chen Xi, 15, is

one of them. She said, "Many people think that playing a card game like this in class is a waste of time. But

in fact, bridge is a very challenging game that helps develop memory and math skills."
