You can download the presentation I have used to explain this tense. You only have to click on the "b" you can see at the left bottom of the presentation, it sends you to the page where you can download it. It is easy!
You can also practise the tenses we have seen by clicking on the left side bar under "Exercises on line" and looking for the tense you want to work. Don't forget to study the rules for the test on Tuesday.
