A、To explain a new requirement for graduation. B、To interest students in a community service project. C、To discuss the problems

Good morning, everyone. Community service is an important component of education here at our university.[16]We encourage all students to volunteer for at least one community activity before they graduate. A new community program called "One on One" helps elementary students who’ve fallen behind. You education majors might be especially interested in it, because it offers the opportunity to do some teaching—that is tutoring in math and English. You’ll have to volunteer two hours a week for one semester. You can choose to help a child with math, English or both. Half-hour lessons are fine, so you could do a half hour of each subject two days a week.[17]Professor Howard will act as a mentor to the tutors. He’ll be available to help you with lesson plans or to offer suggestions for activities. He has office hours every Tuesday and Thursday afternoon. You can sign up for the program with him and begin the tutoring next 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 too, showing that you have experience with children and that you care about your community.[18]If you’d like to sign up or if you have any questions, stop by Professor Howard’s office this week.
