2. Comprehension Check
2.1
Focusing on the main ideas
The article consists of
three stories about pioneers of flight. The first
story is
about a Chinese named Wan Hu,
who made an unsuccessful attempt at spaceflight
2
Howard
Hughes
On
November
2,
1947
in A.D.1500. He built a
spaceship powered by 47 rockets using gunpowder.
His
idea
was
crazy,
but
his
dream
of
flight
came
true
500
years
later
when
China
successfully launched
its first manned Shenzhou V spaceship. The second
one is
about the Spruce Goose, a flying
boat designed to meet the need of transporting
troops and materials during World War
II. It was made entirely of wood and still
holds the record for the greatest
wingspan. Although it was never put to use, many
of its design features have been
incorporated into today’s
cargo planes. The last is
about Leonardo da Vinci, the most
famous artist of the Renaissance. Apart from
his great artistic work, he also drew
sketches of flying devices with flapping wings
controlled and steered by
human pilots.
Five hundred
years later,
a professional
parachutist made a successful jump
using a wood and canvas parachute based on
one of
da Vinci’s
designs/sketches.

2. It was the biggest airplane ever
built up to that time, and still holds the record
for the greatest wingspan. Besides, it
was made entirely of wood.
3. No,
because it was behind schedule and was not
completed until well after the
war.
4. Da Vinci’s flying machines have
wings that flap like birds in flight.
5. Because it is difficult for ordinary
people to understand their passion for flight,
their spirit of innovation, and their
courage to try and make their dream come
true.
