Dear Boris,

___1____

After I had spent a week with my English family, I slowly began to understand their English a little better. ___2____ Students in my group are from different cities of Britain and their dialects (方言) are different too! Some of their accents are quite strong and they also have their own words and expressions.

__3____ Before I came to England I had thought that fish and chips were eaten every day. That’s quite wrong! I get rather annoyed now when I hear all the foolish words about typical English food.

I had expected to see “London fog”. Do you remember our texts about it? We had no idea that most of this “thick fog” disappeared many years ago when people stopped using coal in their homes. But the idea to speak about weather was very helpful. ___4____ On the other hand, habits are different. People tell me what is typical British here in London is not always typical in Wales or Scotland. ___5____

But what is ordinary for all British is that they follow traditions(传统). Probably Britain has more living signs of its past than many other countries. And people have always been proud of having ancient (古老) buildings in capitals, big cities and the countryside.

I will tell you more about Britain in my other letters.

Love from Britain.

Peter
