Sung Ling from Shanghai is staying with her exchange partner, Kate Miller, in San Francisco. On Ling’s first Saturday, the Millers have a barbecue in their garden. They want to introduce Ling to some of their neighbours. Kate also invites some of her friends from school. Before the barbecue, Ling is a little nervours. “What do I say when you introduce me to somebody?” she asks Kate. “Don’t worry, Ling,” Kate says, “It’s very easy. When I introduce you to an older person, for example Grant Summers, our next-door neighbour, I say, “Grant, this is Sung Ling from Shanghai. She’s my exchange partner.” And then I say to you, “Ling, this is Grant Summers. He’s our next-door neighbour.” And you just say, “How do you do, Mr. Summers? It’s nice to meet you.”
