Turn on the radio. A program will come out from a broadcasting station miles and miles away. We know that sounds and music themselves couldn’t travel that distance through space .There must be something that brings the program from the station. But what is this silent carrier ( 载体) ?
This is known as radio waves. However, we can’t see them or even hear them. In fact, nobody knows exactly what they are. Nevertheless( 然而) ，we know that they are made by electricity .
At the broadcasting station, people talk, sing, play musical instruments or make many other sounds. These sounds are changed into electricity. Then from the broadcasting aerial (天线)of a tall tower , electricity sends out radio waves which travel in all directions .And some of them reach your radio aerial. What happens next is a magical thing. The radio waves start an electric current ( 电流) in your aerial like the one that was first made in the broadcasting station . Finally, the loudspeaker in your radio set changes the electricity into sound .Therefore, you hear the program.

As I stood outside with my two dogs yesterday , it was so cold that my nose and face felt frozen ( 结冰的).
Of course, that doesn’t matter to Ricky and Lucy. They have a habit that they must find a place to fight with each other no matter how cold or hot it is.
As cold as it was, I was excited thinking about how wonderful this special cold really was.
Then the sun broke through the clouds and memories of summer’s really hot days came through my mind. I could remember standing in heat of the afternoon, with sweat pouring down my head and the hot, burning sun against my face. I told myself then and there that in the cold of the winter I would wish I had this heat. Because of the special cold, I enjoy the heat more.
So I realized that without the extremes in my life, I would never appreciate the days
When things just right. without the extremes, life would be boring. For example, heath problems remind us that we need to pay more attention to how we live.
Now, I want to start finding a reason to be happy, even if it’s simply the fact that I’m still alive in the world.
