Now in his third Olympics, his    9     (amaze) performance has excited people both at home and abroad. Su Bingtian is really a living legend    10     will surely encourage more young players in their sporting career (事业).

China is the hometown of kites. Most people believe they     1     (invent) 2,500 years ago, during the Spring and Autumn Period.
