My Favorite Sports Team: the Chinese Women’s Volleyball Team
In quite a few sports, Chinese women athletes outshine men athletes. As a girl, I always feel proud of our women table tennis players, badminton players, women divers and gymnasts. But my greatest enthusiasm always goes to the Chinese Women’s Volleyball Team, who, though it has undergone some ups and downs, always presents a positive, inspiring image to the public.
I’ve never missed any major TV coverage of the Chinese women’s team. I can’t help getting excited watching the girls shine in court, with their amazing spikes and blocks, and their never-26
ceasing courage and faith in winning the match. There are times when they lose the game, sometimes with embarrassing result like 0:3; there are years when they suffer a lot of injuries and new players do not match up to the veterans, yet, one must admit that the Chinese girls have been practising very hard all the way.
Recent years have witnessed a difficult period for the team as Russian, American, Cuban, and Brazilian teams have been rising in ranking and winning championships, but I still have faith in our team and give them my support. I wish them good luck in the coming Olympics. (196 words)
