Hi, everyone, this is Susan; welcome to today’s Pronunciation Challenge. For my entire life, I’ve always known the Sahara Desert as what it is: hot, sandy, and dry. Little did I know that there was a time when it was humid, had planation and lakes, and had animals living there! For years now, scientists are working hard, hoping to bring back all the green! Before we talk more, let's take a look at today's sentence and its pronunciation tips.

Sentence

Pronunciation Tips
1. vegetation (the pronunciation of the vowels)
2. width (the pronunciation of dth)
3. continent (the pronunciation of the vowels)
4. an epic; aims to; belt of; the entire (linking sounds)
