ДАЮ 50 БАЛІВ!!! Про яких відомих людей йдеться в текстах:

1. She wrote her first story when she was only six
years old. Her parents wanted her to study French, so
she chose this subject at university, even though deep
down she wanted to study English. After graduation,
she had a few different jobs in London, but still had an
ambition to write books. One day during a long train
journey, she had an idea that would change her life: she
decided to write a book for children. However, it took
her a few years to finish the book. The first twelve
publishers that read the story didn’t like it, but finally
she found one that decided to publish it. Seven years
later, she became the first woman to make a million
pounds from writing books.

2.In high school he worked as a presenter on the
school radio because he had a good voice. While at
college, he signed up for a drama course and first got
interested in acting. However, he wasn’t a very strong
student and quit university before graduation. He
moved to Los Angeles to look for a job on the radio, but
couldn’t find one. Instead, he got small roles in film
productions. Although he was once told that he would
probably never be a successful actor, he continued to
go to auditions. Seven years after his first acting job, he
got a big role in a hit film and became a Hollywood star.
