Present perfect simple or continuous

Dear all,

I need to know a teachable difference between these two sentences:

1- Mike has been repairing the car.
2- Mike has repaired the car.

Thanks for your help,

P.S.: Teachable difference is what I', in need of as I already know the difference myself, but can't pass it down to my students in a smooth way.

If you already know the difference, then all you need worry about is making that difference clear. For me, #1 tells us about Mike's recent activity; #2 tells us that the car is ready to drive.

1- Mike has been repairing the car. (Mike has just finished repairing it or is still working on it)
2- Mike has repaired the car. (Mike is done fixing the car - the work is finished)

1. Action either isn´t finished or has just finished. Indicates a space of time when the action has been done.
2. Action is finished.

1. we focuse our attention on the activity itself, not on the result
2. we are interested with the result not with the activity

Hi
Through pictures you can also let them know the difference. I do it in my classes when I want to show the difference between these two tenses. You can show some one who has just finished repairing the car and is ready to drive it or is ready to hand it to the owner. In another picture that is the continuous one you can show someone who is tired and dirty and show a car that has not been repaired yet. Of course as others mentioned present perfect continuous also refers to finished action as well.

There seemed to be a free trial period. Thereafter it was a paysite. Also, it was aimed at German speakers, so was not very helpful for most of our members.

Not to mention that it's Timmy's brother that is using it. Let him comment about this "lern" portal.
