[单项选择]
I go to the barber’s every three weeks. I don’t like very short hair, so my barber doesn’t cut off much. I have known him for almost four years, and when I go to him, we always talk a lot. He tells me all his news and I tell him all mine. He meets a lot of interesting people in his shop and he talks to most of them, so he always has a lot of news for me.
Every year my barber goes to France for two weeks for his holidays, and when he comes back to England, he has a lot of interesting news. While he is cutting my hair, he tells me about beautiful cities and quiet little villages, strange food and drinks and many other things. I sit there and listen to the old man with open ears. One minute, my barber’s chair is a seat in a French train, and the next minute it became a chair in a restaurant in Paris. Although my barber is old, he always tries new things. He never says, "I have never eaten this food before, so I am not going to eat it now." H
