At the end of yesterday's lesson I mentioned that you could prepare some examples or stories to make your descriptions more interesting (for speaking part 2, and maybe part 3).
When speaking in our own languages, we tell stories all the time. For example, you might tell a member of your family about what happened at work today, or you might tell your friends about a film you saw last night.
The ability to tell a story in English is a sign that you are becoming a proficient user of the language. Test yourself: try telling a story in English now! Start with something easy, like "what I did yesterday".
