In the past 500 years，nothing about people—their clothes，ideas，or languages has changed as much as what they eat.The original (最初的) chocolate drink was made from the seeds of cocoa tree by South American Indians.The Spanish introduced it to the rest of the world during the 1500’s.And although it was very expensive，it quickly became fashionable (时髦的)．In London shops where chocolate drinks were served became important meeting places.Some still exist today.
