Read the passage and answer the
following questions (根据文章内容回答下列问题)
Once a boy wanted to fly. He made a pair of wings. He used some wax (错) to keep the
feathers on the wooden frame. He flew and flew, and flew too close to the Sun. The
Sun melted the wax, and the feathers were blown off by the wind. Down came the
boy into the ocean.
This is just a story. But it tells us that man has always dreamed of
flying. In 1783, this dream came true. Two French brothers invented the hot-air
balloon. It rose a thousand feet high.
It took almost 100 years for man to move from the hot-air balloon to the
first airship. The first airship was invented in the late 1800s. It was a
powered (装有发动 机的) balloon.
In North Carolina, less than twenty-five years later, the Wright
Brothers flew the first airplane. This first flight, in 1903, lasted less than
half a minute! It covered just a few feet.
By the 1960s, man had moved from airplanes to spacecrafts. Today, space crafts
can go around the world in less than two hours. Tomorrow. Who knows?
