Wright brothers: pioneers of the plane

Hundreds of years ago, most people thought that human beings would ________ fly. Yet two brothers tried to break the limits (界限). Orville and Wilbur Wright were the pioneers (先驱) of airplanes.

Orville Wright ________ on August 19, 1871 and his older brother, Wilbur Wright, came to the world on April 16, 1867 in the US. The two started their career (职业) by running a printing (印刷) business and later a bicycle repair shop. But they spent their ________ time working on a flying machine.

“If birds can fly for long periods of time, then ________ can’t I?” Orville Wright said. The brothers studied how birds move through the air and tried to use it on their models.

Finally, on Dec 17, 1903, their first plane took off in the air. The plane had a wingspan (翼展) of 40 feet (about 12 meters). The brothers controlled (控制) it by moving a cradle (支架). Modern aviation was born.

The Wright brothers were not the first to ________ and fly experimental aircraft. But they were the first to invent (发明) aircraft controls. These controls allowed the ________ to fly the aircraft effectively (有效地).
