Usain Bolt wins the Olympic gold in three events. The third is for a 100-mete relay.
Jamaicans in Rio celebrate. Back home in Jamaica, people are very proud of him.
It is a great achievement, but it can also be his last. Bolt is going to retire next year.
Difficult words: relay (a race when runners in a team take turns), celebrate (be happy because of something good), achievement (something good that you do), retire (stop working).
