Read the passage carefully.
Our century has seen great changes in the life and living 
conditions of people. Less than hundred years ago, many 
of the things that we do now seemed impossible. No one 
could imagine that people could fly, or that we could listen 
to our friends thousands of miles away.
Today, radio and television serve many purposes besides 
pleasure and entertainment. They help us to find fish in the 
sea and to land airplanes in bad weather or at night. They 
control the work of large numbers of machines in industry, 
and hold spaceship in their orbits.
