Exploration of the Poles
The North Pole and South Pole are at the top and bottom of the Earth, (25)_______________you won’t find an actual pole to mark the place. The poles are the northernmost and southernmost points on the planet. The poles are the most unfriendly environments on Earth.
In the early 1900s, explorers competed to become the first (26)_______________ ( reach ) the South Pole. From 1901 to 1904, British naval officer Robert Scott made the first attempt. Scott got (27)_______________ ( far ) south than anyone had been before, but he failed to reach the pole.
In 1909, Ernest Shackleton of Britain led an expedition across Antarctica on sleds pulled by dogs. They were only about 100 miles (about 160 kilometers) from the South Pole (28)_______________ a shortage of food forced them to turn back.
Scott finally reached the South Pole in January 1912. But (29)_______________ ( disappoint ) Scott found that Roald Amundsen had beaten him by one month. Amundsen’s expedition arrived at the pole in December 1911. Amundsen was (30)_______________ experienced Arctic explorer, and he had made careful preparations. Scott and his companions died of injury, cold, and hunger on their return from the pole.
In 1914, Shackleton (31)_______________ ( plan ) another expedition to the South Pole. But his ship was crushed by ice, and he had to cross 800 miles (1,300 kilometers) of freezing sea in a tiny boat to survive. Shackleton then returned to save his strandedmen. It was one of the greatest rescue feats in history.
In 1929, Arctic explorer Richard Byrd became the first person who flew over the South Pole. Byrd later pioneered the idea of(32)_______________ ( set )up permanent stations for scientific research in Antarctica. A station called the Amundsen-Scott Base has stood at the South Pole since 1977. |
