14.Benjamin Franklin's inventions reveal a man of many talents and interests.His natural curiosity about things and the way they work made him try to find ways to make them work better.
Ben had poor vision and needed glasses to read.He got tired of constantly taking them off and putting them back on,so he decided to figure out how his glasses let him see both near and far.He had two pairs of glasses cut in half and put half of each hens(镜片)in a single frame.Today,we call them bifocals(双光眼镜).
Everyone knows the story of Ben's famous kite flight.Although he made important discoveries and advancements,Ben did not"invent"the electricity.He did,however,invent the lighting rod which protects buildings and ships from lighting.
In colonial America,most people warmed their homes by building a fire in a fireplace even though it was dangerous and used a lot of wood.Ben figured that there had to be a better way.His invention of an iron furnace stove allowed people to warm their homes less dangerously and with less wood.The furnace stove that he invented is called the Franklin Stove.Interestingly enough,Ben also established the first fire company and the first fire insurance company in order to help people live more safely.
As a postmaster,Ben had to figure out routes for delivering the mail.He went out riding in his carriage to measure the routes and needed a way to keep track of the distance.He invented a simple odometer and attached it to his carriage.
Later,other famous inventors,like Thomas Alva Edison and Alexander Graham Bell,followed in Ben's footsteps by trying to find ways to help people live better.
