Unfortunately, the sound won't download, so add your own using using Audacity (free). Only snag is that you need to make one file for each slide, save it and then add. Fiddly, but easy once you've tried it. Free to use, but not to sell. This is a sample slide, with an amination that works on the ppt. Enjoy.

The French version has a final optional slide, with the weather in the perfect tense.
