When ten-year-old James Ale and his friends went out to play，they had nowhere to go but the streets. The streets were filled with traffic，but the children had no choice. There was no park or playground nearby. One day，a little girl was badly injured by a passing car. James Ale thought the neighborhood needed a park.

For more than a year，James Ale worked for his park. He knocked on doors asking adults to help. He went to City Hall and discussed his idea with the mayor（市长）.At first people did not want to listen to a ten-year-old，but James did not give up. In the end，he won.“Getting the park took a lot of work，”James said.“It was worth it，though，because we needed it.”
