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 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 (古老的) buildings in capitals, big cities and the countryside.

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

Love from Britain.

A.The weather in London is really changeable.

B.I have difficulty in understanding my classmates.

C.Thanks for your nice letter.

D.The family I live with are friendly.E. It’s very different from what I learned at school.

F. Local habits and traditions are not the same as what we knew.

G. But it’s not the language that’s different and surprising.
