     Long ago, poems were recited out loud instead of being written down. When the Greeks first started

the Olympics, they held poetry contests as well as athletic competitions.

     Now, poetry competitions have been revived (恢复). This year 120,000 high school students

competed in the first Poetry Out Loud National Recitation Contest, performing poems from memory

for $100,000 in prizes.

     The first competitions were held in classrooms. The winners went on to schoolwide contests, and

then they competed in city and state competitions. Finally, the 50 state champions, along with the District

of Columbia champion came to Washington, D. C. last week for the last showdown. After the 51

champions competed against one another,12 went on to the finals. Then the field was narrowed to five.

The final five had one last chance to "perform" a poem. The overall champ, Jackson Hille, a high school

senior from Ohio, won a $20,000 scholarship.

     The National Endowment for the Arts and the Poetry Foundation started Poetry Out Loud because

they realized that hearing a poem performed is a different experience from reading it on a page.

     It's not just a matter of saying the words in the right order. It's the tone of voice, the pauses, the

gestures, and the attitude of the person performing that bring the words to life. "Each time we hear

somebody recite a poem, we find something fresh and interesting about it, " says National Public Radio

Broadcaster Scott Simon, master of ceremonies for the finals. Hearing it in a new voice offers something

new to the listener.

     Not only do the people hearing poems have a new experience, memorizing and presenting poems

helps the participants (选手) understand those poems in a new way. Another benefit of a competition

such as Poetry Out Loud is that the participants learn publicspeaking skills that can help them for life.
