     The Wizarding World of Harry Potter theme park will open in Florida in 2009, and will provide attractions

and rides based on places from the Harry Potter books.

     The novels' author JK Rowling has already given her blessing to the project. She said, "The plans I've seen

look unbelievably exciting, and I don't think fans of the books or films will be disappointed."

     Stuart Craig, the man in charge of the design of the park, is an Oscar-winning production designer who

worked on the Harry Potter films so it should be faithful (忠实的) to JK Rowling's vision.

     Stuart Craig said, "Our primary goal is to make sure this expenence is an authentic extension (原著的延伸)

of Harry Potter's world as it is portrayed in the books and films."

     Visitors to the park will be able to explore some of their favourite places from the book such as the village

of Hogsmeade, the Forbidden Forest and, of course, Hogwarts Castle, where Harry goes to school.

     Although fans can look forward to a holiday in the Harry Potter theme park,many will be saddened by the

fact that the best-selling series is now drawing to a close.

     The final instalment (分期连载的一部分)in the series, Harry Potter and the Deathly Hallows, will be

published on 21 July, and to mark the event JK Rowling is to read extracts (摘录) from the book to a select

audience at midnight on the day of publication.

     Rawling has announced that two characters die in the final book, but has not revealed (透露) if Harry is

one of them so fans will have to wait to find out the fate of their magical hero.
