In 1880, fourteen-year-old Matthew Henson loved to hear sailors tell tales of their exciting lives at sea. One day he made up his mind. Baltimore was the nearest large seaport(海港). The next morning he set out on the forty-mile journey to try to find       on a sailing ship.

In Baltimore, Henson found a job as a cabin boy on a beautiful ship. For the next five years, Henson     around the world. With the help of the ship’s captain and other members of the crew, Henson learned mathematics, history, geography, and many other     .

Unable to find work anywhere else, Henson took a job in a      shop in Washington, D.C. One day in 1887, a man came in to buy a hat. The man, Lieutenant Robert Peary, asked the owner if he knew anyone with     at sea. Peary would soon travel to South America for the U.S. government. He needed experienced men to go with him.

The shop owner knew about the young man’s skills and experience on ocean journeys,    he introduced Peary to Henson. Using his map-reading and sailing skills, Henson proved      to be a worthy and smart seaman. One day Peary told Henson about his real dream: to be the first man to stand on “the top of the world” at the North Pole. He asked Henson to help him make his dream    .

Over the next five years, the two explorers(探险家) made two trips together to the Arctic(北极). However, they were not able to reach the pole either time. The cold, wind, and ice were     than either of them had ever imagined.

In 1908, Peary and Henson were ready to make their final challenge at reaching the North Pole. With four guides, they made a mad dash straight across the ice. Peary’s feet were so frostbitten(冻僵的) that he had to be pulled on a dogsled.    April 1909, Henson’s instruments showed they were standing at the North Pole. Together Henson and Peary planted the American flag in the snow.
