Dear Steve,

     You asked me to write you something about my visit the British Isles. I will tell you the culture of the

people of the British Isles.

     The culture of the British Isles is influenced by the culture of the people on the European Mainland many

centuries ago. In the fifth century, people from different part of north Europe settled in England, brought

their own culture and languages with them. Their languages formed the basis for English. Some of the native

population moved to the inland, mountainously parts of the islands, to Ireland, Scotland and Wales, which

they continued speaking their own languages. In 1066 England was conquered by the French. For the next a

few hundred years, the upper classes spoke French when the common people spoke English. The result of

this French influence was whether the English language ended up with many French words such as table,

animal and age.

     I will stop here, and hope me enjoy it.

                                                                                                                                      Best wishes,

                                                                                                                                       Lee
