     On October 19,1959, the first Special English program was broadcast (广播) on the Voice of America.

It was an experiment. The goal was to communicate by radio in clear and simple English with people whose

native language was not English. Experts said the goal was admirable, but the method would not work.

However, _____. The Special English programs quickly became some of the most popular on VOA. And

they still are.

     Forty years later, Special English continues to communicate with people who are not fluent in English.

But during the years its role has expanded. It also helps people learn American-English. It succeeds in helping

people learn English in a non-traditional way. And it provides listeners, even those who are native English

speakers, with information they cannot find elsewhere.

     Today, Special English broadcasts around the world seven days a week, five times a day. Each half-hourly

broadcast begins with ten minutes of the latest news followed by 20minutes of feature (特写报道)

programming. There is a different short feature every weekday about science, development, agriculture, and

environment, and on the weekend about news events and American idioms. These programs are followed by

in-depth (深入的) 15 minutes features about American culture, history, science, medicine, space, important

people or short stories.
