    The first car was invented not by an Englishman，but by an American. His name was Henry Ford.

    Henry was born in a poor family. He was the eldest of six children. When he was a boy, he became interested in watches and machines. When he was twelve years old, his mother died. Soon he had to work in a machine shop for two dollars and fifty cents a week. In the evenings he repaired watches for another dollar a week. The hard life made him strong and able.
