C

Danielle Steel, America’ s sweetheart, is one of the hardest working women in the book business. Unlike other productive authors who write one book at a time, she can work on up to five. Her research time before writing takes at least three years. Once she has fully studied her subjects, ready to dive into a book, she can spend twenty hours nonstop at her desk.

Danielle Steel comes from New York and was sent to France for her education. After graduation, she worked in the public relations and advertising industries. Later she started a job as a writer which she was best fit for. Her achievements are unbelievable: 390 million copies of books in print, nearly fifty New York Times best-selling novels, and a series of "Max and Martha" picture books for children to help them deal with the real-life problems of death, new hobbies and new schools. Her 1998 book about the death of her son shot to the top of the New York Times best-selling list as soon as it came out. Twenty-eight of her books have been made into films. She is listed in the Guinness Book of World Records for one of her books being the Times best-seller for 381 weeks straight.

Not content with a big house, a loving family, and a view of the Golden Gate Bridge, Danielle Steel considers her readers to be the most important resource (资源) and has kept in touch with them by e-mail. While she is often compared to the heroines (女主人公) of her own invention, her life is undoubtedly much quieter. But, if she does have anything in common with them, it is her strength of will and her inimitable(无与伦比的) style. There is only one Danielle Steel.

Danielle Steel is different from other writers in that().

A. she can write several books at the same time

B. she often does some research before writing a book

C. she is one of the most popular American women writers

D. she can keep writing for quite a long time without a break
