Pumpkin
(南瓜)
carving
at
Halloween
is
a
family
tradition.
We
visit
a
local
farm
every
October.
In
the
pumpkin
field,
I
compete
with
my
three
brothers
and
sister
to
seek
out
the
biggest
pumpkin.
My
dad
has
a
rule
that
we
have
to
carry
our
pumpkins
back
home,
and
as
the
eldest
child
I
have
an
advantage-I
carried
an
85-pounder
back
last
year.
This
year,
it
was
hard
to
tell
whether
my
prize
or
the
one
chosen
by
my
14-year-old
brother,
Jason,
was
the
winner.
Unfortunately
we
forgot
to
weigh
them
before
taking
out
their
insides,
but
I
was
determined
to
prove
my
point.
All
of
us
were
hard
at
work
at
the
kitchen
table,
with
my
mom
filming
the
annual
event.
I’m
unsure
now
why
I
thought
forcing
my
head
inside
the
pumpkin
would
settle
the
matter,
but
it
seemed
to
make
perfect
sense
at
the
time.
With
the
pumpkin
resting
on
the
table,
hole
uppermost,
I
bent
over
and
pressed
my
head
against
the
opening.
At
first
I
got
jammed
just
above
my
eyes
and
then,
as
I
went
on
with
my
task,
unwilling
to
quit,
my
nose
briefly
prevented
entry.
Finally
I
managed
to
put
my
whole
head
into
it,
like
a
cork
(软木塞)
forced
into
a
bottle.
I
was
able
to
straighten
up
with
the
huge
pumpkin
resting
on
my
shoulders.
My
excitement
was
short-lived.
The
pumpkin
was
heavy.
“I’m
going
to
set
it
down,
now,
”
I
said,
and
with
Jason
helping
to
support
its
weight,
I
bent
back
over
the
table
to
give
it
somewhere
to
rest.
It
was
only
when
I
tried
to
remove
my
head
that
I
realized
getting
out
was
going
to
be
less
straightforward
than
getting
in.
When
I
pulled
hard,
my
nose
got
in
the
way.
I
got
into
a
panic
as
I
pressed
firmly
against
the
table
and
moved
my
head
around
trying
to
find
the
right
angle,
but
it
was
no
use.
“I
can’t
get
it
out!
”
I
shouted,
my
voice
sounding
unnaturally
loud
in
the
enclosed
space.
注意:
续写词数应为150左右。
It

five
or
six
minutes

it

longer.

video
to
Facebook,
but
it
was
only
then
I
realized
she’d
been
filming
the
whole
time.
The
video
cut
before
my
rescue—Dad
got
me
to
push
my
head
farther
into
the
pumpkin
so
mom
could
reach
in
and
undo
the
rubber
band
round
my
ponytail.
I
emerged
with
knotted
hair,
a
sore
chin
and
my
nose
covered
in
pumpkin
flesh.
The
video
was
posted
the
Monday
before
Halloween.
By
the
end
of
that
day,
it
had
over
1,
000
views.
By
Wednesday
morning
we
were
getting
5:
00
am
calls
from
TV
breakfast
shows
and
then
the
international
media—the
video
started
racking
up
hundreds
of
thousands
of
views.
When
I
went
on
a
youth
camp,
I
was
recognized
by
the
children
I’d
never
met.
The
pumpkin
also
became
a
minor
celebrity.
Passers-by
would
knock
and
ask,
“Which
is
the
very
pumpkin
in
the
video?
”
before
taking
pictures
with
it.
Thank
you
