Present Perfect

Hello everyone!
Here we are again to try to improve your English ! here you have some exercises to revise what you should have learned last year. As I told you in class, it is quite important that you learn irregular past participles by heart. You can use an infallible method: take either a pen or a pencil, a piece of paper, a list of irregular verbs and COPY, COPY,COPY until your hand bleeds (just joking!!!), IT DOES WORK!!!!
Click on the links on the worksheet for grammar explanation. Then do the exercises and bring them to class for correction. Also here you have some on line exercises for further practice.
 hope you enjoy!
