Dear Peter,

I’m very glad to receive your e-mail asking for information about the host family we have arranged﹀you to stay with．

Locating in a beautiful and quiet neighborhood, the house was big enough to enable you to have a room of your own．Apart from the convenient public transportation, our private car will make your visits difficult．Because all the family members can speak fluently English and have outgoing personalities, I’m sure you will have no trouble to communicating with them．Above all, they hosted the American student last year, through that they gained lots of experience．In addition, the hostess cooking will guarantee you a wonderful chance of tasting delicious Chinese food．

Hope you enjoy your stay here.

Yours,

Li Hua
