I'll just leave here a couple of links more, so can have as much practice as you can take!!! Just click on the exercise number to give it a try. The more you practise, the higher probability of remembering when to use either a gerund or an infinitive (with or without to) when it comes to real communication.
If you remember, we also mentioned, though just briefly, that we usually place a gerund after prepositions, except in a few cases. This is an exercise to practise which prepositions go after certain verbs. Enjoy!
