Serena Williams

Today for the S.L.J I had to write three things I have learned about either about Serena Williams or Venus Williams, we also have to write what we still want to know about that person. I choose  Serena Williams.  The three thing I learnt was that she is a famous tennis player, she was born on the 26 September 1981 and she is 38 years old. I still want to know why she wanted to play tennis?
