IV.话题写作
　　阅读下面材料,
根据其内容和所给段落开头语续写两段,
使之构成一篇完整的短文。
The
Mesmerizing
Canyon(峡谷)
　　I
woke
up
in
the
harsh,
damp
weather
of
the
shining
Grand
Canyon.
My
ears
rang
from
the
screeching
of
the
group
leader
yelling
to
get
up.
I
got
up
as
fast
as
I
could,
hoping
I
was
going
to
do
something
fun
today.
I
heard
the
apprentice
yelling
for
people
to
get
on
the
boat.
As
I
was
still
trying
to
wake
up,
I
smelled
the
fresh
air
just
like
the
roses
in
my
aunt’s
garden.
The
group
leader
made
us
all
get
on
the
raft
and
then
we
immediately
left.
When
we
arrived
at
our
destination,
it
turned
out
that
they
both
were
just
playing
a
trick
on
us
and
wanted
to
surprise
us
with
a
beautiful
glistening
waterfall.
We
were
all
very
glad
as
we
saw
the
waterfall.
We
all
wanted
to
go
up
to
it
and
walk
in
it.
We
were
required
to
climb
up
big
rocks
and
hike
little
distances
in
order
to
get
to
the
waterfall,
but
it
was
really
worth
it.
We
left
the
waterfall
and
set
up
a
camp
near
it.
My
grandma
handed
me
a
tent
and
said,
“You
do
it
yourself,
and
I
want
you
to
learn
some
things.
”
I
took
30
minutes
to
set
up
the
tent
and
tried
to
make
it
perfectly
symmetrical(对称的).
However,
when
my
grandma
and
I
were
about
to
get
in
it,
it
fell
over.
We
sighed
and
my
grandma
walked
over
to
the
other
family’s
tent
and
sat
down
perfectly
stationary.
So
I
knew
I
had
to
do
it
over
again,
and
I
took
about
5
minutes
to
set
up
the
tent
with
my
previous
knowledge.
I
also
added
some
sticks
to
the
top
of
the
tent
for
some
decoration.
As
the
tent
swayed,
I
was
required
to
put
some
weight
on
the
edges
of
the
tent.
So
I
put
two
rocks
on
each
side
of
the
tent.
My
grandma
walked
over
and
was
very
impressed.
That
really
inspired
me
to
keep
learning
new
things.
When
my
grandma
and
I
woke
up,
there
was
already
breakfast
waiting
for
us.
There
was
a
mixed
variety
of
different
foods
on
the
table,
such
as
bacon,
beef
jerky,
eggs
and
sausages.
注意:
续写词数应为150左右。
　　After
we
ate
breakfast,
we
got
on
the
boat
where
we
floated
down
the
river.

Step
2　妙笔成篇
　　After
we
ate
breakfast,
we
got
on
the
boat
where
we
floated
down
the
river.
“Today
we
are
going
to
hit
the
biggest
rapids
and
see
the
incredible
waterfalls,
”
called
out
the
group
leader.
It
was
up
to
him
to
lead
us
there.
All
people
were
excited
and
prepared
for
the
journey
in
the
canyon.
Five
minutes
later,
huge
crashing
waves
appealed
to
us
all.
They
were
the
biggest
waves
everybody
had
ever
seen.
As
we
entered
the
rapids,
everybody
was
thrown
around
but
luckily
our
boat
was
not
upside
down
and
nobody
was
thrown
off
the
boat.
After
the
rapids
were
over,
everybody
was
wet
and
excited
widely.
　　The
night
fell
on
us.
We
set
up
a
camp
near
the
exit
of
the
canyon.
This
time
it
took
only
five
minutes
for
me
to
put
up
the
steady
camp,
after
I
put
two
rocks
on
each
side
of
the
tent.
What
I
did
caught
my
grandma’s
eye.
Putting
up
the
tent
by
myself
in
such
a
short
time
impressed
her
very
much.
She
was
glad
that
I
learned
new
things
in
the
camping
at
last.
From
this
experience
I
understood,
just
as
the
saying
goes,
“Nothing
is
difficult
in
the
world
if
you
put
your
heart
into
it”.
Thank
you
