问题     Probably the most famous kite in history was Benjamin Franklin’s. In 1752 he flew a silk kite in a thunderstorm to prove that lighting and electricity were the same thing.
    But kites have been used for many hundreds of years. Most experts believe kites originated in China about three thousand years ago. At first they were not used as a way to have fun on a breezy afternoon; the Chinese army used them as signals. A kite’s color, its painted pattern, and the way it was flown could send messages far away. Kites were also used as beacons (信标), to distribute pamphlets, and. even to transport bombs.
    Chinese soldiers tied bamboo shoots or stiff paper to their kites. When the kites soared overhead, the wind blowing through the bamboo or paper made a harsh whistling sound. The noise terrified the enemy, and they ran.
     Just as today’s kids imitate adults by playing with toy guns and toy airplanes, Chinese children quickly began flying kites.
    Kites have been used through the centuries in religious ceremonies, at festivals, and as tools for studying weather. Kites contributed to people’s knowledge as they began to build airplanes..
