Much has been said and written about heroes now, mainly because many people think we have too few of them. There are many different kinds of heroes, but they usually seem to have two things. First, heroes show their great power by actions. Second, heroes can be tested by the time. Because of these good points, we need to choose our heroes carefully.

Olympic winner Jackie Joyner-Kersee tells young people to work hard. She hopes that if someone tries to copy her, it will be because she has got success by working hard. She says that a hero should affect another person’s life.

Poet Maya Angelou believes that a hero encourages people to treat others well. A hero should show politeness, courage, patience, and strength all the time. A hero should encourage others to follow him with actions, even though only in small ways.

Author Daniel Boorstin suggests that, “Celebrities are people who appear on newspapers, but heroes are people who make history.” If a person is truly a hero, he or she will not be soon forgotten.

We all need heroes. We need to be able to respect (尊重) people around us. Many times , the greatest heroes are the people we can see every day — our relatives, friends, and neighbours — who will never give up when facing difficulty. The parent who supports our family, the teacher who will make more money at another job but chooses to help students — all these people can be considered as heroes. A hero sets a good example, an example that encourages others to follow.
