The latest podcast describes how to hear and make the /s/ sound as in racer (like a stock car racer or a Formula 1 racer) and the /z/ sound as in razor (the thing you shave with). It's an important difference, and if you are from Poland, the Czech Republic or Slovakia, Hungary, Romania, Russia, or a similar Eastern European country, you probably have trouble with the difference, particularly in the final position (the difference between "scarce" which means "hard to find or uncommon", like a scarce natural resource, and "scares" as in "he scares me" meaning to frighten.)
As I said it's an important difference. So check out the podcast, I hope it helps.

Until next time, take care! Drink plenty of cold water, iced tea, lemonade or other drink so you don't get dehydrated because it is getting hot and humid again. Enjoy the beach while you can, it'll be four feet of snow again before you know it!
