第二节:完形填空(共20小题;每小题1.5分,满分30分)
Once,
looking
for
stories
on
the
back
roads
of
Ohio,
we
weren’t
getting
on
smoothly.
A
beekeeper
we’d
been
told
about
was
away
from
home
16
we
called
on
him.
An
amusement
park
where
we
thought
we
might
find
a
17
had
shut
down
for
the
season.
We
began
to
get
a
little
18
.
When
19
a
farmhouse,
we
found
a
banner(横幅)between
two
trees
in
the
front
yard.
The
banner
20
in
huge
letters:
WELCOME
HOME,ROGER!
We
drove
21
for
a
mile
or
two.
Somebody
said,
“Wonder
who
Roger
is ”
We
22
,
went
back
there
and
knocked
on
the
door.
Roger
was
a
soldier
on
his
way
home
from
war.
His
23
knew
he
was
coming,
but
weren’t
sure
what
day
he
was
going
to
24
.
We
asked
if
they’d
mind
if
we
brought
the
camera
into
the
house.
Roger’s
mother
said
it
would
be
all
right
if
we
could
give
her
a
few
minutes
to
25
.
We
weren’t
there
more
than
an
hour,
talking
to
those
people
who
were
all
26
about
Roger
coming
home
and
taking
pictures.
In
the
bus
as
we
27
on
that
afternoon,
I
wrote
a
simple
story
letting
Roger
28
all
the
soldiers
coming
home
from
war.
We
sent
the
29
with
the
story
to
New
York,
and
Walter
Cronkite
put
it
on
the
Evening
news.
30
has
any
of
our
stories
caused
such
a
reaction
from
viewers.
The
CBS
switchboard(总机)
31
up
that
night
with
dozens
of
calls
from
people
32
by
it
in
some
way,
and
hundreds
of
letters
came
in,
some
of
them
suggesting
that
the
story
be
33
.There
was
so
much
34
throughout
that
that

had
to
report
a

nights

第三部分:阅读理解(共20小题;每题2分,满分40分)
A
San
Francisco
is
going
to
do
what
many
other
cities
have
already
done—provide
free
bicycles
to
the
public.
The
mayor
of
San
Francisco
supports
the
bicycle
program.
He
wants
to
improve
the
terrible
traffic
problems
in
the
city.
At
first,
40
to
60
bikes
will
be
available
only
to
city
workers.
People
will
give
their
old
bikes
to
the
city
to
use
in
the
program.
If
this
program
is
successful,
one
day
more
than
1,000
bicycles
will
be
available.
Everyone,
not
just
city
workers,
will
be
able
to
use
these
bicycles.
People
in
Fresno,
California
already
have
a
free
bicycle
program.
In
fact,
this
idea
began
in
Amsterdam
over
40
years
ago.
These
programs
encourage
citizens
to
get
out
of
their
cars
and
onto
pollution-free
bikes.
Fresno’s
Yellow
Bike
Program
puts
about
forty
bicycles
around
the
city.
The
bikes
are
painted
bright
yellow
so
people
know
they
can
take
them.
When
people
take
a
yellow
bike,
they
can
ride
to
work
or
to
shopping
areas,
and
then
leave
the
bike
for
the
next
rider.
Some
people
worry
that
the
free
bikes
will
be
stolen.
However,
theft
hasn’t
been
a
problem
in
free-bike
cities
by
now.
While
most
people
think
the
bike
program
is
a
good
idea,
only
a
few
say
they
will
use
it.
“I
will
still
drive
my
car,”
says
Joanna
Greene.
“San
Francisco
has
a
lot
of
hills.
My
office
is
at
the
top
of
Potrero
Hill.
I
don’t
think
I’m
in
good
shape.
And,
wouldn’t
I
have
to
carry
a
helmet
with
me
all
the
time ”
Phil
Chung
agrees,
“There
is
too
much
traffic.
Riding
a
bicycle
can
be
dangerous.
There
are
not
very
many
bike
lanes.”
He
continues,
“Plus,
it’s
too
cold
in
the
winter.
And
what
if
you
ride
a
bike
to
work,
and
then
there
isn’t
one
to
ride
home ”
Program
leaders
know
there
will
be
problems.
But
they
think
it’s
worth
trying.
“It’s
not
the
solution
for
everyone,”
states
Sylvia
Pass.
“But
if
just
one
hundred
people
use
it
every
day,
that’s
one
hundred
cars
that
aren’t
on
the
streets,
one
hundred
parking
spaces
that
aren’t
used.
I
think
it’s
a
great
beginning.”
36.

We’ve
all
heard
the
phrase
“love
is
patient”,
but
one
couple
in
Michigan,
took
this
phrase
to
a
whole
new
level.
On
Monday,
February
13,
Willard
Mason
sat
down
to
talk
about
his
relationship
with
the
love
he
lost
more
than
60
years
ago.
Good
fortune
and
fate(命运)
recently
helped
the
couple
reunite.
In
1941,
Willard
Mason
and
Llah
Ost,
both
senior
2
students,
became
engaged
to
be
married
and
began
planning
their
lives
together.
But
Willard
moved
away
to
work
at
Willow
Run
Bomber
Plant,
where
he
met
and
fell
in
love
with
a
woman
named
Helvi.
He
broke
off
his
long
distance
engagement
to
Llah
and
married
Helvi
in
1942.
Llah
later
found
love
with
someone
else.
Both
had
happy
marriages
and
raised
families.
Then,
in
2003,
Helvi
died.
A
year
later,
Willard
found
himself
back
in
his
hometown,
where
by
chance,
he
ran
into
Llah’s
brother.
He
informed
Willard
of
the
death
of
Llah’s
husband,
and
encouraged
him
to
call
her.
After
that
first
phone
call,
the
couple
began
dating.
Willard
made
the
drive
from
his
home
near
Houghton
Lake
to
Llah’s
home
in
Adrian.
On
one
such
trip,
he
blacked
out,
and
his
car
hit
a
tree.
He
was
rushed
to
a
hospital,
where
tests
showed
that
he
needed
a
new
pacemaker.
Willard
moved
closer
to
Adrian
and
asked
Llah
to
move
in
with
him.
She
gladly
accepted.
“We
get
along
perfectly,”
Willard
told
AZ
Central
on
Monday.
“We’ve
never
had
an
argument,
she’s
a
great
cook,
and
she
takes
care
of
me.”
Although
both
Willard
and
Llah
are
saddened
by
the
62
years
they
spent
without
each
other,
neither
seem
to
have
any
regrets.
Willard
told
AZ
Central,
“You
don’t
know
how
our
lives
might
have
turned
out
if
we’d
gotten
married
in
1941,
but
now
she
has
a
wonderful
family,
and
so
do
I.”
40.
What
does
the
writer
probably
mean
by
saying
the
phrase
“love
is
patient”
A.
To
win
love
needs
a
good-natured
tolerance
of
waiting.
B.
Love
can
make
someone
ill
in
hospital.
C.
Love
can
also
help
one
set
a
world
record.
D.
To
win
love
needs
a
whole
new
level
of
cooking
skill
41.
What
caused
the
failure
of
Willard
and
Llah’s
engagement
A.
Their
unhappy
company
with
each
other.
B.
Llah’s
new
love
with
someone
else.
C.
Their
being
far
away
from
each
other.
D.
Willard’s
escape
from
his
family.
42.
After
Willard’s
wife
died,
he
came
back
to
his
hometown
_______
there.
A.
in
order
to
date
with

husband’s
death
C.
to
ask
Llah
to
move
in
with
him
D.
and
was
told
that
he
needed
a
new
pacemaker
43.
Which
of
the
following
should
be
the
best
title
for
the
passage

Situated
in
the
South
West
of
England,
between
Exeter
and
Plymouth,
Torquay
is
one
of
the
most
popular
holiday
resorts
in
Britain.
It
provides
sophisticated(精致)entertainment,
sports
of
every
kind
and
cultural
facilities,
all
set
in
a
position
of
outstanding
natural
beauty.
Visitors
can
choose
between
luxury
hotels
by
the
sea,
with
private
suites(套房),
swimming
pools,
and
comfortable
but
less
expensive
guest
houses.
There
are
camping
sites,
too,
and
hundreds
of
houses
displaying
“B
&
B”
signs.
As
well
as
a
number
of
small
quiet
bays,
which
are
ideal
for
beach
barbecues(野餐)
away
from
the
crowds,
Torquay
has
large
sandy
beaches
where
you
can
buy
refreshments(饮料)and
hire
deck
chairs,
boats
and
even
beach
houses.
There
are
large
areas
of
grassland
overlooking
the
sea,
and
miles
of
winding
cliff
paths
for
walkers
who
just
want
to
enjoy
the
scenery
and
what
is
often
said
to
be
the
healthiest
air
in
the
country.
For
the
sportsmen
and
women
there
are
opportunities
not
only
for
golf,
tennis,
but
also
for
water-skiing,
hang-gliding
and
deep-sea
fishing.
After
a
day
in
the
open
air,
there’s
lots
to
do
in
the
evenings,
too.
There
are
plenty
of
discos,
the
occasional
opera
or
ballet,
and
summer
variety
shows
in
the
seafront
theatres.
For
the
children,
there
is
a
beautiful
model
village
with
a
complicated
railway
layout
which
is
remarkably
realistic—especially
when
the
lights
are
all
on
at
night.
Of
course,
there’s
no
need
to
spend
your
whole
holidays
in
Torquay.
Only
a
short
drive
away
is
Dartmoor
National
Park,
where
you
can
walk
for
miles
through
dramatic,
unspoiled
countryside,
or
picnic
by
beautiful
rivers
and
streams.
Or,
nearer
to
home,
you
can
sail
across
Tor
Bay
to
the
lovely
old
fishing
village
of
Brixham.
Torquay
seems
to
have
something
for
everyone.
But
don’t
take
my
word
for
it—come
and
see
for
yourself.
44.

Everyone
was
born
with
his
own
built-in
burglar
alarm(报警器).
It’s
called
the
sense
of
sight
and
sound.
Unfortunately,
many
of
us
go
around
with
the
alarm
switched
off.
We
don’t
see
the
stranger
wandering
outside
the
house
next
door.
We
don’t
notice
the
sounds
from
the
flat
upstairs.
(Weren’t
they
supposed
to
be
on
holiday )
The
police
can
only
do
so
much
to
prevent
crime(犯罪).
There
never
can
be
enough
of
them
to
guard
every
home
in
every
town.
So
they
need
your
help
in
fighting
with
the
burglars(窃贼),
and
the
car
thieves.
Not,
of
course,
by
setting
out
to
have
a
go
every
time
you
see
something
suspicious(可疑的).
It’ll
always
be
the
job
of
the
police
to
arrest
criminals(逮捕罪犯).
But
by
acting
as
a
line
of
communication
between
them
and
your
community.
For
example,
you
probably
know
far
more
about
your
immediate
neighborhoods
than
the
police
ever
could.
A
stranger
in
someone’s
garden
would
probably
be
far
more
obvious
to
you
than
it
would
to
even
the
local
police,
if,
of
course,
you
were
on
the
look-out.
That’s
the
whole
idea
behind
the
Neighborhood
Watch
schemes,
springing
up
around
the
country
to
create
a
spirit
of
watchfulness
within
a
community,
anything
suspicious
being
reported
to
the
police.
It’s
early
days
yet,
but
results
so
far
are
very
encouraging.
The
crime
figures
are
already
dropping
in
many
of
the
areas
running
the
scheme.
And
all
due
to
people
like
you.

The
underlined
word
“them”
refers
to
______.
A.
criminals
B.
the
police
C.
neighbours
D.
strangers
49.
The
advertisement
points
out
that
many
people
______.
A.
are
not
ready
to
help
the
police
B.
are
not
as
watchful
as
they
could
be
C.
don’t
look
after
their
gardens
well
D.
don’t
tell
their
neighbors
about
their
holidays
50.
One
of
the
ways
we
could
help
prevent
crime
is
to
______.
A.
turn
on
the
alarm
system
in
our
home
B.
try
to
stop
criminals
from
escaping
C.
look
out
for
people
behaving
suspiciously
D.
inform
the
police
if
we
hear
noises
upstairs
51.
The
purpose
of
the
advertisement
is
to
_______
in
their
neighborhood.
A.
ask
people
to
join
the
police
force
B.
advise
people
how
to

their
homes
C.

people
about
the

D.

You
might
think
that
“global
warming”
means
nothing
more
than
a
rise
in
the
world’s
temperature.
But
rising
sea
levels
caused
by
it
have
resulted
in
the
first
evacuation(撤离)
of
an
island
nation—the
citizens
of
Tuvalu
will
have
to
leave
their
homeland.
During
the
20th
century,
sea
level
rose
8-12
inches.
As
a
result,
Tuvalu
has
experienced
lowland
flooding
of
salt
water
which
has
polluted
the
country’s
drinking
water.
Paani
Laupepa,
a
Tuvaluan
government
official,
reported
to
the
Earth
Policy
Institute
that
the
nation
suffered
an
unusually
high
number
of
fierce
storms
in
the
past
ten
years.
Many
scientists
connect
higher
surface
water
temperatures
resulting
from
global
warming
to
greater
and
more
damaging
storms.
Laupepa
expressed
dissatisfaction
with
the
United
States
for
refusing
to
sign
the
Kyoto
Protocol,
an
international
agreement
calling
for
industrialized
nations
to
reduce
their
greenhouse
gas
emissions(排放),which
are
a
main
cause
of
global
warming.
“By
refusing
to
sign
the
agreement,
the
US
has
effectively
taken
away
the
freedom
of
future
generations
of
Tuvaluans
to
live
where
their
forefathers
have
lived
for
thousands
of
years,”
Laupepa
told
the
BBC.
Tuvalu
has
asked
Australia
and
New
Zealand
to
allow
the
gradual
move
of
its
people
to
both
countries.
Tuvalu
is
not
the
only
country
that
is
vulnerable(易受影响的)
to
rising
sea
levels.
Maumoon
Gayoon,
president
of
the
Maldives,
told
the
United
Nations
that
global
warming
has
made
his
country
of
311,000
an
“endangered
nation”.
52.
The
passage
is
mainly
about
_______.
A.
rapid
changes
in
earth’s
temperature
B.
bad
effects
of
global
warming
C.
moving
of
a
country
to
a
new
place
D.
reasons
for
lowland
flooding
53.
According
to
scientists,
the
direct
cause
of
more
and
fiercer
storms
is
______.
A.
greenhouse
gas
emissions
in
industrialized
nations
B.
higher
surface
water
temperatures
of
the
sea
C.
continuous
global
warming
D.
rising
sea
levels
54.
Laupepa
was
not
satisfied
with
the
United
States
because
it
did
not
______.
A.
agree
to
reduce
its
greenhouse
gas
emissions
B.
sign
an
agreement
with
Tuvalu
C.
allow
Tuvaluans
to
move
to
the
US
D.
believe
the
problems
facing
Tuvalu
were
real
55.
The
country
whose
situation
is
similar
to
that
of
Tuvalu
is
______.
A.
Australia
B.
New
Zealand
C.
the
Maldives
D.
the
United

第五节:One
possible
version:
A
Traffic
Accident
Last
Sunday,
an
old
lady
aged
about
seventy
was
badly
hurt
in
a
traffic
accident
at
the
second
crossing
of
Xinhua
Road.
It
was
9:30
p.m.,
and
there
were
many
cars
in
the
street
at
that
time.
The
old
lady
was
crossing
the
street
when
a
young
man
riding
a
bicycle
rushed
up
and
knocked
her
down.
The
accident
happened
so
suddenly
that
it
had
been
some
time
before
the
other
people
in
the
street
understood
what
was
happening.
The
old
lady
was
badly
hurt
and
couldn’t
move
at
all.
Someone
called
the
First
Aid
Center
and
soon
some
doctors
came
in
their
ambulance
and
carried
the
lady
to
the
hospital.
The
police
said
that
it
was
the
young
man’s
fault
because
he
didn’t
see
the
red
light
turning
on.
