THE
FATE OF THE airship
In
1937, the Zeppelin company launched the first
~atlantic
(1)
service with its great airship, the Hinderburg.
Travel
by airship was faster and more comfort
(2)
than travel by ship, and people had been looking for the
Hinderburg's
first
flу
(3)
for some time.
Most
airships were designed to work with helium to keep the airship
buoyant, but the Americans rejected Germany’s request for helium
which is flame
(4),
but was not industrially available at that time. As a result, the
Zeppelin was full
(5)
with hydrogen. It was a bomb waiting to explode.
A
few minutes before the arrive
(6) to
New Jersey, the passengers went to the windows to wave to the people
waiting for them on the ground below. It was at that moment that the
great ship caught fire. 36 people died in an explode
(7).
Two
years later the remaining Zeppelins were destruction
(8) and
the age of airships as a means of transportation was over. However,
airships have still been used for polar explore

,
warfare and advertising. This and similarity
(10)
tragedies have made people very caution
(11) about
the use of hydrogen as a fuel for transport, but with careful
planning it can be used at least as save
(12)
as petrol. Many scientists believe that we should run a hydrogen
economic
(13).
Hydrogen can be extracted quite cheaply from water by electrolysis.
Much science
(14)
and technological effort is being spent on effective store
(15)
and transport systems.

MARVELS
OF TECHNOLOGY
The
twentieth century has witnessed many spectacle
(1)
technical developments, but nowhere more evidence
(2)
than in transport. Up until the 1820’s when the steam engine was
invented, transport on land relied on human or animal force and its
efficient
(3)
depended on the decent road system. Similar
(4), sea
travel depended on muscle power and predict
(5) winds.
The nineteenth century relied heavy
(6) on
steam to power trains and boats for
transport
(7)
of goods and passengers, and it was not until the invent
(8) of
the motor car that road transportation became essence
(9) again.
But of course the most impress
(10)
breakthrough has been in air transport.
The
speed with which people can travel vast expand
(11)
of the planet has not only greatly increased the possible mile
(12)
an
average person covers in his lifetime, but it
has
also
changed our perceive
(13)
of the world. It is now define

a much smaller place than it
