听力原文: Community service is an important component of education here at our university. We encouraged all students to volunteer for at least one community activity before they graduate. A new community program called "One On One" help elementary students who've fallen behind. The education majors might be especially interested in it because it offers the opportunity to so some teaching—that is, tutoring in math and English.
You'd have to volunteer two hours a week for one semester. You can cheese to help a child with math, English, or both. Halfhour lessons are fine, so you could do a half hour of each subject two days a week.
I'm sure you'll enjoy this community service... and you'll gain valuable experience at the same time. It looks good on your resume, toot—showing that you've had experience with children and that you care about your community. If you'd like to sign up, or you have any questions, stop by Professor Dodge's office this week.
