Passive Voice for 3rd ESO

As you told me you wanted extra activities to reinforce your knowledges about active and passive voice, here you have a list of links to do it:

http://www.ego4u.com/en/cram-up/grammar/passive/exercises?simple-past
These two links are to change active sentences into passive.
