Dear Mary,

     I've been in England for two months now. I hope you don't think I have forgotten you. There have been

so many places to see and so many things to do that I've not had much time to write letters.

      I will soon be starting my studies at King's College. So far I've been learning about England and British

ways of living. I will tell you about London. There are lots of books you can read and lots of pictures you can

look at. I am sure you'll be more interested to know what I think about the life here.

     I find some of the customs (风俗) new and interesting. People here don't shake hands as much as we do in

Europe. During the first few weeks I was often surprised because people didn't put out their hands when I met

them. Men raise their hats to women but not to each other.

                                                                                                                                   Yours,

                                                                                                                                     Gina
