【答案解析】[听力原文]
   Once every year for the last few years, we have visited our friends in a small tiny little village in the middle of France. And they bought a cowshed, and it was literally a cowshed not fit to live in. And they have gradually made it better and renovated it. And it's in a beautiful position. It's on the top of a hill. And for miles around you can see this beautiful countryside. And I think there is only one other house. So you do need a car and you take the ear into the tiny little village where there are about four or five shops and a very nice restaurant where you can go and have a five-course meal with very little money. And also near is a very big lake, because this place is in the .Poor Don, and there are lots of lakes there. And we go there most afternoons and wind surf and sail. Also there is a very nice market, French Market, there once a week, where you get lovely parties, lovely fresh fish, really good fresh fish and lovely bowls and baskets which the local people have made. I like this part of France very much. But I think it's a shame that there are too many English people there.
   How often does the speaker visit his friends in France?
