On July2, 1937, Amelia Earhart( an American pilot) and Fred Noonan left New Guinea for Howland Island in the Pacific. This was the longest and most dangerous part of their t 小题1:   around the world. Earhart had trouble soon after the plane took off. The weather was very bad, so she had to f小题2: at 3,000 metres. Going this high, the plane used fuel quickly.

After about 20 h  小题3: , Earhart and Noonan got close to Howland Island. The island was o 小题4: about 65 miles (英里) away, but the bright sun was shining in their faces so they couldn’t see it. Near Howland, a ship was w 小题5:  for the plane. Earhart contacted the ship: “We don’t have enough fuel,” she said. The ship tried to stay in touch with her b 小题6:  got no answer. Finally, the ship called for help. People looked for Earhart and Noonan for days. However, they found nothing.

What happened to Amelia Earhart? No one knows for sure. D 小题7:  the flight, she probably moved in the wrong direction(方向) because the sun was bright and it was d 小题8:  to see. So she got lost; soon after, her plane ran out of fuel, and she died at sea. Another idea is that she survived(幸存) the plane crash(飞机失事), s 小题9:  to a lonely island, and later died there. Still other think she survived the crash and secretly returned to the U.S. with a new identity(身份).

Till now, none of these i 小题10:  has been proved. People are still wondering about them. (Noonan’s body has never been found either.) No matter what happened, Earhart probably died as she wished. “When I go,” she said, “I’d like best to go in my plane.”
