I have to admit that this is one of the grammar topics that caused me more distress when studying English. That’s is why I’ve tried to prepare a presentation that can be understood and followed by all my students.
Apart from the presentation, I would also like to leave you some links where you can do online activities to review the topic.
- New English File, Grammar, 4b, online activity.
English-Hilfen.de: Assorted online activities.
ESL GAMES: Online game for 1 or 2 players.
Finally, I hope you enjoy watching the presentation. If you have further questions, just leave them in the comments section.
