Our new foreign students are going to arrive very soon, and here are some ways to communicate with them politely.
How close do you stand when you talk to a friend? You can stand close to people in the Middle East but don’t stand too close to North Americans! Give them more personal space.
Do you know How to touch people correctly? Chinese girls often walk arm in arm with their friends. South Americans sometimes hold your arm when they talk to you, so you can’t move away! But in Britain many people don’t like other people to touch them at all.
Do you look at people when you talk? In some places, it isn’t polite to look at people when you talk, but in other countries it isn’t polite to look somewhere else. In Britain and the US, people usually look at each other when they talk.
And how do you say goodbye? That’s easy, wave(挥手) to say goodbye. But be careful! In Greece, it’s not at all polite! In fact, it’s very rude!

Community service is an important component of education here at our university. 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. Your 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'd 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.
Professor Dodge 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've had experience with children and that you care about your community. If you'd like to sign up, or if you have any questions, stop by Professor Dodge's office this week.
1.What is the purpose of the talk? ____________
