三、阅读理解
The
most
frightening
words
in
the
English
language
are,
“Our
computer
is
down.”
You
hear
it
more
and
more
when
you
are
on
business.
The
other
day
I
was
at
the
airport
waiting
for
a
ticket
to
Washington
and
the
girl
in
the
ticket
office
said,
“I’m
sorry,
I
can’t
sell
you
a
ticket.
Our
computer
is
down.”
“If
your
computer
is
down,
just
write
me
out
a
ticket.”
“I
can’t
write
you
out
a
ticket.
The
computer
is
the
only
one
allowed
to
do
so.”
I
looked
down
on
the
computer
and
every
passenger
was
just
standing
there
drinking
coffee
and
staring
at
the
black
screen.
Then
I
asked
her,
“What
do
all
you
people
do?”
“We
give
the
computer
the
information
about
your
trip,
and
then
it
tells
us
whether
you
can
fly
with
us
or
not.”
“So
when
it
goes
down,
you
go
down
with
it.”
“That’s
good,
sir.”
“How
long
will
the
computer
be
down?”
I
wanted
to
know.
“I
have
no
idea.
Sometimes
it’s
down
for
10
minutes,
sometimes
for
two
hours.
There’s
no
way
we
can
find
out
without
asking
the
computer,
and
since
it’s
down
it
won’t
answer
us.”
After
the
girl
told
me
they
had
no
backup(备用)
computer,
I
said.
“Let’s
forget
the
computer.
What
about
your
planes?
They’re
still
flying,
aren’t
they?”
“I
couldn’t
tell
without
asking
the
computer.”
“Maybe
I
could
just
go
to
the
gate
and
ask
the
pilot(飞行员)
if
he’s
flying
to
Washington,”
I
suggested.
“I
don’t
know
which
gate
to
send
you
to.
Even
if
the
pilot
goes
to
Washington,
he
can’t
take
you
if
you
don’t
have
a
ticket.”
“Is
there
any
other
airline
flying
to
Washington
within
the
next
few
hours?”
“I
wouldn’t
know,”
she
said,
pointing
at
the
dark
screen.
“Only
‘IT’
knows.
It
can’t
tell
me.”
