This book introduces 15 sets of human inventions throughout history, such as architecture like the Pyramids in Egypt, sculptures like the Eiffel Tower, international events like the Olympics, foods like Coca-Cola, cultural events like the Nobel Prize, entertainment like Video Games, and intangible cultural heritage like Korean Letters. Throughout the book, young readers explore familiar human achievements and practice describing them in the passive voice. While the descriptions may be longer than what they’re used to, this is the moment they’ll realize how much their English has improved.
