Alexander Graham Bell was born in Scotland.He only attended school(上學(xué))for five years,from the time he was 10 until he was 14,but he never stopped learning.He read the books in his grandfather's library.
When he was a teenager,he and his brother Melly used the voice box of a dead sheep to make a speaking machine that cried,"Mama!"This created even more interest in human speech and how it worked.
Bell drew up a plan for the telephone and continued to experiment.He knew he would have to work quickly to get the patent(專利權(quán)).He worked hard and succeeded at last.Because Bell had the patent,he had the right to be the only one to produce telephones in the U.S.for the next 19 years.
He showed the invention to Queen Victoria of England and she wanted lines to connect her castles(城堡).By 1917,nearly all of the United States had telephone service.
Bell continued to invent other things.He became a U.S.citizen,but he died in Canada at the age of 75.
