There are some famous buildings that everyone can recognize. When you see a picture of a sports stadium that reminds you of a bird’s nest, you probably know it is the Olympic stadium in Beijing. When you see a picture of a famous concert hall that reminds you of a sailing ship, you probably know it is the Sydney Opera House in Australia. Buildings like these are easily recognized everywhere in the world. They were designed to look like other things if people use their imaginations.
