Is this an ok introduction paragraph for a three paragraph paper? Is the thesis there?

Question

My favorite thing to do in my spare time is to play tennis. The best part of playing tennis is that it is a very thrilling and rewarding sport to play. Fortanutly, it is not an intensely challenging sport, but the better you are at playing, the more fun you have. In addition, playing tennis teaches you a lot about…..

Answer 1

Yes this is a good introduction for your tennis paper.  and Yes you have a thesis and it's pretty solid.

P.S. (You spelled fortunately wrong in the 3rd line)

Answer 2

I'd say your thesis is the 3rd sentences which now you have to riff off on by providing examples pro and con and generally discussing it Example:

showing why it is not an intensely challenging sport ( others might well disagree like those who can serve at 90mi/hr or who make millions in tournaments won by a failed volley) and also why the better you are at playing the more fun you have ( well, this is a no brainer but you can get into how you get better and if you get to a certain level then you will get chosen to play doubles which has its own challenges and discuss that.

Answer 3

use better word choice.... instead of coming straight out with what your fav spare time thing to do is try to kind of surpise the reader with it...

Like:

A ball and a stick, all it takes is one partner and my spare time is complete, tennis my favorite.
