A bit more of grammar (Present Perfect Simple & Present Perfect Continuous)

Hi, there!

Here you have a link   to give you some extra practice in the use of both tenses. Remember that some of you kind of struggled a bit with  them the other day in class.
I hope  this can help you understand it all much better.
