Помогите сделать английский рассказ более простым

Ниже оно, но это сложно для меня нужно упростить до школьного уровня, мне его надо будет пересказать.

I'm glad I have a computer. I can't even imagine, what could I do if I didn't have one!
In everything I do it helps me a lot.
I can communicate with my friends all over the world just sitting at my desk.
I can find anything I need in just a few seconds.
Finally, I can save loads of information, fotos, movies and computer programs
in a tiny space of my hard disk.
Unfortunately, there are also numbers of interesting games that I empt to play.
But knowing, how much time I AM going to SPEND for nothing and how little
benefits I AM going to take from that, I prefer not even to start playing.
All in all, A computer is an irreplaceable gadget for me while I'm a student
and I'm very grateful for this invention of the twenty FIRST century!
