根据短文内容, 选择正确答案。

    Amelia Earhart was born in America in 1897. As a little girl, she could climb trees and catch rats. When she was seven years old, she discovered she was interested in flying. In 1920, Amelia took a plane and knew she had to fly! Just days after that, she took her first flying lesson. Six months later, she bought her own plane!

    A Life-Changing Flight On June 18^th, 1928, Amelia became world-famous because she flew across the Atlantic with others as the first woman. And then she was called the “Queen of the Air”.

Making and Breaking Records Although Amelia was well-known in the flight, she never stopped practicing. In 1932, she became the first woman to fly across the Atlantic by herself, and later in 1935, she was the first person to fly over the Pacific from Hawaii to California by herself.

    The Last Flight When her 40th birthday was coming, Amelia prepared for her biggest challenge-an around-the-world flight. On June 1, 1937, she began her 46, 671-kilometer flight. Something unlucky happened on June 29. She never came back again.
