Hello XXXX,
I’ve attached our class slides for you to have a look at. You must have been waiting for this email since the end of our lesson. It may well have been a tough lesson for you but well done on your hard work – you were fantastic!
On the final slide you’ll find your homework assignment. I was bound to give you one!
Please read the example carefully, and then prepare a description of an event you went to in the past. You’re bound to find all the help and instruction you need on that last slide.
In addition, here are some useful exercises:

Have a great day,
