                The answer is radio waves. We can not see radio waves or feel
            them or even hear them. In fact, nobody knows exactly what they are.
            But we do know that they are made by electricity, and we have
            learned how to use them.
            At the broadcasting station people talk or sing, instruments (乐器)
            play, doors slam(砰) ,and all of these make sound waves. The sound
            waves reach the microphone, and here they are changed into
            electricity. Then from a tall tower called the broadcasting aerial
            (天线) ,electricity sends radio waves. The waves travel in every
            direction, and some of them reach our radio aerial. Now a wonderful
            thing happens. The radio waves start an electricity current (电流) in
            our aerial like the one that was first made in the broadcasting
            station. Finally, the loudspeaker in our set changes electricity
            into sound, and we hear the program.
