Welcome to Learning English, a daily 30 minute program from the Voice of America.

I'm Ashley Thompson.

And I'm Mario Ritter Jr.

This program is designed for English learners,

so we speak a little slower and we use words and phrases especially written for people learning English.

On today's program you will hear stories from Anna Mateo and John Russell.

Later, Brian Lynn presents this week's technology report.

We close the show with the lesson of the day from Jill Robbins and Andrew Smith.
