In the week preceding your presentation go through some English media - English-speaking newspapers, the SZ supplement or on the internet! Choose a news item which interests you or which you think is important/interesting for the rest of the class.
Prepare a little presentation of 5 minutes, talking about what happened, where it happened, who was involved, what led to the incident, why is it important, etc. Some visual support is always appreciated.
You will get a certain week for which you have to prepare your presentation. In that week, be ready to present your item any lesson.
