触电的蛇
First
listen
and
then
answer
the
question.
听录音，然后回答以下问题。
What
caused
the
fire?
At
last
firemen
have
put
out
a
big
forest
fire
in
California.
Since
then,
they
have
been
trying
to
find
out
how
the
fire
began.
Forest
fires
are
often
caused
by
broken
glass
or
by
cigarette
ends
which
people
carelessly
throw
away.
Yesterday
the
firemen
examined
the
ground
carefully,
but
were
not
able
to
find
any
broken
glass.
They
were
also
quite
sure
that
a
cigarette
end
did
not
start
the
fire.
This
morning,
however,
a
firemen
accidentally
discovered
the
cause.
He
noticed
the
remains
of
a
snake
which
was
wound
round
the
electric
wires
of
a
16,000-volt
power
line.
In
this
way,
he
was
able
to
solve
the
mystery.
The
explanation
was
simple
but
very
unusual.
A
bird
had
snatched
up
the
snake
from
the
ground
and
then
dropped
it
on
to
the
wires.
The
snake
then
wound
itself
round
the
wires.
When
it
did
so,
it
sent
sparks
down
to
the
ground
and
these
immediately
started
a
fire.

参考译文
消防队员们终于扑灭了加利福尼亚的一场森林大火。从那时起，他们一直试图找出起火的原因。森林火灾时常由破碎的玻璃或人们随手扔掉的香烟头引起。昨天，消防队员仔细查看了地面，但未能发现碎玻璃。他们还十分肯定火灾也不是由烟头引起的。然而今天上午，一个消防队员偶然发现了起火的原因。他发现了缠绕在16,000伏高压线上的一条死蛇。就这样，他解开了起火之谜。解释很简单，却异乎寻常。一只鸟把蛇从地上抓起来，然后把它扔到了电线上。于是蛇就缠住了几根电线。当它这样做时，把火花送到了地面，这些火花立刻引起了一场大火。
