We are now living in the
modern society. Most of
the energy we use for heating, lighting,
transportation
and
manufacturing
(
制
造
业
)
comes
from
fossil
(
化
石
)
fuels.
These
are
carbon-based fuels from oil, coal and natural gas. When we burn these fuels we release heat which
p__81___ the energy.




There
are
three
main
disadvantages
to
using
these
fuels.
Firstly,
they
are
causing
climate
problems because of the G__82___ Effect. When we burn fossil fuels they produce carbon dioxide
which causes global warming. Secondly, when we have used up all our coal, oil and natural gas,
we will have n__83___ left to burn. Thirdly, they are not very efficient. The internal combustion
engine
(
内燃机
)
that
we
use
in
most
cars,
trucks
and
buses,
for
example,
is
only
about
14%
efficient.




Scientists are working on another fuel
—
hydrogen. There are a couple of advantages to using
hydrogen as a fuel. Firstly, because two-thirds of the e__84___ surface is water and water is made
of
hydrogen
and
oxygen.
There
is
an
almost
unlimited
supply
of
hydrogen.
Secondly,
burning
hydrogen
does
not
cause
global
warming.
Thirdly,
it
is
much
more
efficient
than
carbon-based
fuels.




Unfortunately there are problems with hydrogen at the present time: there is the problem of
separating (
分离
) it from water c__85___, and there is the difficulty of storing it. It can be stored
under pressure but high pressure tanks are far from safe. It can also be stored as a liquid but only
at extremely low temperatures. It seems likely, therefore, that there will have to be a completely
new technology before hydrogen replaces fossil fuels. S__86___ these problems is an urgent (
急
迫的
) matter. Although China, India and Australia have huge amounts of cheap coal, and there are
still l__87___ oil and gas reserves(
储藏量
) elsewhere, the effects on the planet
’
s climate will be
bad if they are used.
