IV.阅读理解
The
two
boys,
Tom
and
Huck,
were
very
frightened
because
they
worried
about
being
found
by
Injun
Joe
and
his
friend.
Through
the
hole
in
the
floor,
the
two
boys
upstairs
saw
the
men
eat
and
talk.
Then
the
men
were
tired
and
fell
asleep.
Tom
and
Huck
lay
there
for
a
very
long
time.
Finally,
the
two
men
woke
up
and
lifted
up
a
stone
in
the
ground
and
took
out
some
money
they
had
stolen.
Then
Injun
Joe
lifted
up
another
stone
and
found
a
box.
“What's
this？”
Injun
Joe
asked.
The
two
men
pulled
the
box
out
of
the
ground
and
opened
it.
The
two
boys,
Tom
and
Huck,
could
see
there
was
much
money
in
it.
They
were
very
excited.
“There's
thousands
of
dollars
in
the
box！”
said
his
friend.
“It
must
have
been
left
here
by
Murrel，”
said
Injun
Joe.
“What
will
we
do
with
it?
”
“We'll
take
it
to
my
hideout(隐匿处)．”
“Number
one
or
number
two？”
“Number
two,
under
the
cross.”
Then
Injun
Joe
and
his
friend
saw
some
tools
in
the
corner
and
decided
to
go
upstairs.
But
the
stairs
broke
when
Injun
Joe
stood
on
them!
So
the
two
men
left
the
house
and
went
towards
the
river.
Tom
went
home
as
quickly
as
he
could.
The
next
day,
the
two
boys
remembered
the
“Number
two”，
thinking
this
must
be
the
number
of
the
room
in
the
hotel.
They
got
all
the
keys
they
could
find
anywhere.
But
Tom
discovered
the
door
was
not
locked.
He
opened
it!
