In those days, airplanes were not nearly as common as they are today. Earhart was 12 years old before she ever saw an airplane, and she did not take her first flight until 1920. America Earhart was so thrilled by her first airplane ride that she quickly began to take flying lessons.   Her first instructor was Neta Snook, one of the first women to graduate from the Curtiss School of Aviation(飞行).Earhart borrowed mone from her mother to buy a two-seat plane. She got her US flying licence in December 1921, and in 1923, Earhart received her international pilot’s license—only the 16th woman to do so.   Amelia Earhart wasn’t afraid to break down barriers. After flying across the Atlantic as a passenger in 1928, Amelia Earhart’s next goal was to complete a transatlantic crossing(??横跨大西洋)alone. In 1927, Charles Lindbergh became the first person to make a solo nonstop flight across the Atlantic. In 1932, exactly five years after Lindbergh’s flight, Earhart became the first woman to repeat the feat(壮举).   She decided that her next trip would be to fly around the world. In March 1937, she flew to Hawaii with fellow pilot Paul Mantz to begin this flight. Earhart lost control of the plane on takeoff, however, and the plane had to be sent to the factory for repairs.   In June, she went to Miami to again begin a flight around the world, this time with Fred Noonan as her navigator(领航员).The pair made it to New Guinea in 21 days, even though Earhart was tired and ill. During the next leg of the trip, they departed New Guinea for Howland Island, a tiny island in the middle of the Pacific Ocean. July 2, 1937, was the last time Earhart and Noonan communicated with a nearby Coast Guard ship. They were never heard from again.   56.What would be the best title for the passage?      A Amelia Earhart’s Last Flight      B Amelia Earhart—the First woman to Fly Around the World      C Amelia Earhart’s Life Story      D Amelia Earhart—a Woman pilot of Great Courage   57.
