About one hundred years ago, there was a girl in the USA. She loved children very much and wrote many songs for children. One of them was the song Good Morning To You. The song was very popular at that time among children, but not all grown-ups (成年人) knew it. The girl was very poor. Once her friends invited her to a little child's birthday party. She felt happy but sad because she had no money to buy a present for him. Finally she decided to sing the song Happy Birthday in the melody (曲调) of Good Morning to You for the little boy. When her friends heard the song at the party, they were very happy. 'How wonderfully she is singing! We have not heard this song before. It's a special present,' said someone. And they learned to sing it together. Later, the song became very popular throughout the world. People like it because it's simple and friendly. (     )1. Happy Birthday is an old song.
