Now I can play tennis as good as before,so today I enjoyed tennis.
Indeed I can play tennis well,I can't stop hitting a powerful shot because my stroke style enables me to do so.
I played doubles.
In one match,opponents were just in front of me.They were just in front of the net.
I volleyed.It was very powerful and passed between them.
In another match, opponents shot.It was very weak and bounced very higher,so I smashed very powerfully.It went to the coaching staff.
Neither of these shots didn't come back to me.

Moreover,older ladies were very slow!So they weren't able to shot well.This makes me very frustrated.

I want to improve my skills so I will join to a tennis club activities.

Oh no! It took about 20 minutes to translate it to English! If my teacher know it,he will get angry!
