When he died in 1931, Americans wondered how they could best show their respect for him. One suggestion was that the nation observe a minute or two of total blackout. All electric power would be shut off in homes, streets, and factories. Perhaps this suggestion made Americans realize fully what Edison and his inventions meant to them.

In this way they honored the man who had done more than anyone else to put a great force of electricity at his countrymens fingertips.翻译下列年代：1 nineteen seventy-one_ 2 eighteen eighty-five_3. eighteen seventy-six 4.1927_ 5.1976_ 6. 2010_二、自主学习文化背景导读How Americans showed their respect for Edison Thomas Alva Edison was awarded more patents on inventions than any other American.
