What is my favourite sport ? This is a kind of
ball games. I can play it indoor. But sometimes
I can play it outsides. I can play it with one
or three players. I cant play it with my hand. I
need a table and a net. The ball is
40mm(millimeters)(??). The ball can be white or
orange. Chinese players are good at it.

music. She can jump high and stand steady(???).
She can also act in a film. She won a gold medal
(??)at the Sydney Olympics in 2000. But now she
is playing a bigger role(??) for the Beijing 2008
Olympic games?.
