Sandwiches are delicious, but do you know how the first sandwich came? An English earl(伯爵)called John Montagu made it three hundred years ago. Montagu was interested in card games. He would play these games with his friends for a long time. He found it too boring to stop his games for meals.
One day, in the middle of a game, Montagu was served a meal of sliced meat with bread. At that time, Montagu was playing the game that needed its players to cover one card over another. As Montagu looked at both the game and his food, an idea came to his mind.
He took a piece of bread, put a piece of meat on it and covered that with another piece of bread. Then Montagu could play cards with one hand and eat his meal with another.
Montagu's friends called the new meal sandwich because Montagu's full title was “the Earl of Sandwich”.

Each person has his own way to have fun. Some like sports. Some like playing chess or cards. But a large number of people enjoy listening to music.
Nowadays, music has become an important part of our life. We can listen to music on CDs, on radio or on TV. Also, we can search the Internet to find the song we like. It's the easiest way to enjoy the music that we like. Also we can download (下载)our favorite songs from the Internet for free. If we have a Walkman (随身听),we can hear music everywhere. It can give us pleasure if we are sad. It can cheer us up, too. When we are tired, it can make us relaxed.
Different people like different kinds of music. Young people like pop music. Maybe old people like gentle and quiet music. Different music can express different feelings. When we are happy, we like to listen to jubilant (欢快的) music. When we are unhappy, we want to hear soft music. We need different kinds of music in different moods. We can get different feelings from music. Music is the best friend of human beings. We can't imagine what life would be like without music.
