The idea of this book came from an article I read on newspaper, which gave some examples on how modern airports are turning themselves into big shopping center and playground. You probably won’t believe it: Singapore Changi airport has world’s tallest slide, a cactus garden, a sunflower garden and a butterfly garden; Hong Kong airport has a gold court; Amsterdam Airport Schiphol has a large collection of contemporary sculpture throughout. You may stay there for days and never be bored.
The words has been made simple for kids to read and focus on words with “th”. To help kids differentiate the soft and hard pronunciation of “th”, all the words with “th” in this book is soft sound. I will make one more book with all the hard sound “th” words.
