     Many people believe Henry Ford invented the automobile (汽车). But Henry Ford did not start to

build his first car until 1896.That was eleven years after two Germans developed the world's first

automobile.Many people believe Henry Ford invented the production line that moved a car's parts to the

worker, instead of making the worker move to the parts.That is not true, either.Many factory owners used methods of this kind before Ford.What Henry Ford did was to use other people's ideas and make them

better.And he made the whole factory a moving production line.

     In the early days of the automobile, almost every car maker raced his cars.It was the best way of

gaining public notice.Henry Ford decided to build a racing car.Ford's most famous race was his first one.

It was also the last race in which he drove the car himself.

     The race was in 1901, at a field near Detroit.All of the most famous cars had entered, but only two

were left: the Winton and Ford's.The Winton was famous for its speed.Most people thought the race was over before it began.

     The Winton took an early lead.But halfway through the race, it began to lose power.Ford started to

gain.And near the end of the race, he took the lead.Ford won the race and defeated the Winton.His name appeared in newspapers and he became wellknown all over the United States.Within weeks of the race,

Henry Ford formed a new automobile company.In 1903, a doctor in Detroit bought the first car from the

company.That_sale was the beginning of Henry Ford's dream.Ford said: "I will build a motor car for the

great mass of people.It will be large enough for the family, but small enough for one person to operate and care for.It will be built of the best materials.It will be built by the best men to be employed.And it will be

built with the simplest plans that modern engineering can produce.It will be so low in price that no man

making good money will be unable to own one."

     The Model T was a car of that kind.It only cost $850.It was a simple machine that drivers could

depend on.Doctors bought the Model T. So did farmers.Even criminals.They considered it the fastest and surest form of transportation.Americans loved the Model T. They wrote stories and songs about it.

Thousands of Model T's were built in the first few years.
