Ann, Currently, we are working on Unit 7 (In the Hotel) in the "Beginners' Course" and on Unit 4 (Meals) in the "Main Course".
At the lessons we use the flash for: 1) reading texts during the warming-up activities
2) drilling grammar exercises in headphones
3) listening to the texts in the "Additional Material" for reproducing the gist and giving the details
Moreover, all of the students were registered on the forum, so they are free to listen to the audiomaterials in the corresponding branch. There are two more new pupils who haven't yet got the flash, I will take care of it next week.
