     On October 19, 1959, the first Special English program was broadcast 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 (令人敬畏的), but the method would not

work. They were proved wrong. 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. 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-hour

broadcast begins with 10 minutes of the latest news followed by 20 minutes of feature 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.

     Three elements make Special English unique. It has a limited vocabulary of 1,500 words. Most are simple

words that describe objects, actions or emotions. Special English is written in short, simple sentences that

contain only one idea. And Special English is spoken at a slower pace, about two-thirds the speed of Standard

English. This helps people learning English hear each word clearly. It also helps people who are English

speakers understand complex subjects.

     Through the years, Special English has become a very popular tool for teaching English, even though it

was not designed as a teaching program. It succeeds in helping people learn English in a non-traditional way.

In countries around the world, English teachers assign Special English to their students. They praise it for

improving their students' ability to understand American English and for the content of the programs.

Universities and private companies in many countries produce packages of Special English materials for

students' use.
