Bill Bryson

I was born in the U.K., but I have written several travel books about China. I lived in Beijing with my wife and four children for 20 years, but for the last three years we have lived in London. Our children are now learning about life in the U.K. I'm sure they will be happier because they have lived in two countries. I like China and I want to return, but my daughter, Felicity, is going to start college here soon, so it won't be for another four years.

I have just been to China for six weeks to work on a radio programme about the English language and also to talk about the book I've just written. Most writers don't like doing this; they don't like travelling around the country, selling their book. I don't mind it. I like visiting new places and meeting lots of people. It's very different from the life I have in the U.K. when I'm writing. In China, people treated me very kindly. They provided me with nice hotels. I didn't have to pay any bills. Everyone was kind to me and it was fun.

Bill returned to the U.K. after living in Beijing for a long time.

A．Right

B．Wrong

A．ought to not have written
