Bi Sheng invented Movable Type in China in the 11th century.
Telephone: The inventor Alexander Graham Bell made the first telephone call in 1876. "Mr Watson,
come here. I want you," he said to his assistant ( 助手) over the phone line. And with those famous
words, the world was about to get much smaller.
Airplane: The Wright brothers made the first powered flight in 1903. Air travel has made the faraway
places suddenly become a lot closer.
Satellites (卫星) : The Soviet Union sent up the world's first satellite in 1957. This began the Space
Age. Satellites have helped scientists study the earth. Much of our knowledge of the world has come
from the information recorded by satellites.
Internet (互联网) : When the Internet was created in 1969, only a few people knew about it.
