次の英文を読んで、あとの問いに答えなさい。 <千葉日大第一改 J.K.Rowling is the author of the Harry Potter books. J.K.'s name is *Joanne Kathleen. She was born in 1965 in a small town near *Bristol, England. Joanne lived with her parents and her sister. The Rowling family was not rich. Joanne did not go to special schools. ( 1 ) She loved to read and write stories. Joanne went to *Exeter University, and she graduated in 1987. After graduation, she moved to London and worked there at different office jobs. In her free time, she wrote stories. In 1990, Joanne's mother died, and she was sad. ( 2 ) She saw an *ad in the newspaper for a job as an English teacher. The job was in *Portugal. She had an *interview, and she got the job. In Portugal, Joanne married a Portuguese man. The next year, Joanne had a daughter, but she was not happy in her marriage. She left Portugal with her daughter and went to live in *Edinburgh, Scotland, near her sister. Life was very difficult for Joanne. She took care of her daughter. She was alone, and nobody helped her. She had no money and no job. Then one day, on a train, she thought about the Harry Potter story. She began to write that story. Joanne liked to go to a coffee shop to write. (3) She drank coffee and wrote. Her daughter slept beside her. After five years, Joanne finished writing the first Harry Potter book. She sent it to many book publishers. ( 4 ) Finally, a publisher liked it, but the publisher said, “This is a children's book. Adults won't read it. You won't make a lot of money." In 1997, Joanne's dream to publish her book came true: Harry Potter and the Sorcerer's Stone was in the bookstores. Children and their parents loved the book, and it became famous all over the world. Now Harry Potter is in sixty-five languages. The publisher was wrong about one thing: Everyone loves Harry Potter children and adults. Over 100 million books were sold in 1999. Then two Harry Potter books became popular movies. J.K.Rowling wrote four more Harry Potter books after that. All those books became movies, too! On January 11, 2007, J.K.Rowling finished her seventh and last Harry Potter book. She will continue to write, but not Harry Potter books. The question is, what will people do without Harry Potter? 注 Joanne Kathleen ジョアン キャスリーン(人名) Bristol ブリストル Exeter University エクスター大学 ad Portugal ポルトガル (国名) interview Edinburgh エディンバラ (地名) (1) ①~④の( に適するものを,ア~エから1つずつ選び,記号で答えなさい。 She sat there for many hours. 7 She wanted to leave England.
