| How the Swan got a long hock Swans at first didn't have long necks but they had beautiful feathers, and they didn't paddle like ducks, they swam. The 1 at that time were ugly, and kicked their short legs to swim. The swans wouldn't 2 the ducks swim with them, which angered the ducks. One day while the swans and ducks were 3 about which group would swim first, some geese came over to see what was the matter. They listened, and found that the swans thought that they should use the pond first because they were much 4 . But they also found that the ducks thought that they should use it first because it was their turn. Then a goose said that they should 5 the pond since it was rather large. The swans got mad at this. So a fight broke out 6 them. The ducks were pulling at the swans feet, and the geese were biting the swans necks, and pulled as 7 as they could. About an hour later the fight ended. The ducks and geese stood there looking at the swans. They had pulled the swans necks out 8 far that they couldn't hold their heads up. But after that day swans, ducks and geese shared all the ponds 9 , and there were no taking turns. But still today the swans have fairly 10 necks. The ducks however are no longer ugly; they are pretty, and a little more graceful (优美的).  | |||
