A fisherman was good at playing the flute (长笛). He played very well. His friends and neighbours often got together to enjoy (欣赏) his music.
Then, the fisherman thought, “If I play the flute for fish, they will come to me too.”
The next day, he brought his flute to work. When he came to the river, he sat under the tree and started to play. He played very well, but there weren’t any fish coming to him.
The fisherman didn’t give up. He played the flute again and again. Still, no fish came to him. At last, he said angrily, “Stupid fish, you have no ear for music.”
Then he took out his net and started to work. He caught a lot of fish.

3．The fisherman gave up playing after the first try.
4．The fisherman caught a lot of fish with his music.
