Concerning the Group Presentations you are working on for next week, someone asked me if they could include a little bit about the culture and history of their tourist location site. I think that is very appropriate for some sites, and can be included in the introduction. It's a good idea in most cases also to show a map of your tourist site, so that people will know where it is. Remember the text says 10 minutes is the time for one presentation with a group of 5. If it's a little less than that, however, it's okay, as long as it is a quality PowerPoint presentation.
Another point: You can practice your pronunciation by giving the speech on your smart phone as if you are sending a message to someone....using the microphone instead of keying in the letters. If your pronunciation is good, it will automatically type the correct text you have.
