第二节：完形填空(共20小题;每小题1.5分,满分30分)
June
was
lying
by
the
Olympic
size
swimming
pool
in
her
new
swimsuit.
She
was
really
hot
and
dived
into
the
water.
16
else
was
in
the
pool.
The
refreshing
water
cooled
her
body
immediately,
which
17
her
to
continue
doing
some
laps
there.
Not
having
swum
in
the
past
several
years
and
being
a
bit
out
of
18
,
June
began
to
tire
19
.
“Ah,
no
pains,
no
gains,”
June
thought
to
herself.
June
20
to
swim,
realizing
her
head
was
21
.
Breathing
became
difficult.
Her
vision
wasn’t
so
22
.
She
saw
the
lifeguard
and
a
couple
others
around
the
pool.
No
sense
in
23
anyone.
She
continued.
She
found
24
in
the
middle
of
the
pool.
Deciding
not
to
make
a
scene,
she
continued
to
swim.
25
,
she
made
it
to
the
other
side
of
the
pool.
Nausea
(恶心),
weakness
and
exhaustion(精疲力竭)
26
it
difficult
for
June
to
get
out
of
the
pool.
27
she
stood,
her
body
slowly
shook
back
and
forth,
losing
her
28
.
Realizing
she
needed
help
but
29
to
even
say
anything,
she
30
the
pool
side
and
stood
there.
Several
minutes
later
she
had
enough
energy
to
only
31
her
body
up
out
of
the
pool.
Sitting
at
the
side
of
the
pool
with
her
feet
in
the
water
she
felt
that
someone
was
32
at
her.
It
was
the
lifeguard.
June
was
just
able
to
33
her
hand,
telling
him
she
was
okay.
Have
you
ever
found
yourself
in
a
34
where
you’re
in
trouble
and
you
don’t
ask
for
help？
There
is
nothing
35
in
asking
for
help.
June
could
have
drowned.
However,
we
all
have
the
tendency,
as
June
did.

第三部分：阅读理解(共20小题;每题2分,满分40分)
A
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
if
he’s
flying
to
Washington,
”
I
suggested.
“I
wouldn’t
know
what
gate
to
send
you
to.
Even
if
the
pilot
was
going
to
Washington,
he
couldn’t
take
you
if
you
didn’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.”
By
this
time
there
were
quite
a
few
people
standing
in
lines.
The
word
soon
spread
to
other
travelers
that
the
computer
was
down.
Some
people
went
white,
some
people
started
to
cry
and
still
others
kicked
their
luggage.

Traveling
can
be
a
way
to
gain
life
experiences,
especially
during
Spring
Break
—a
week-long
school
vacation
in
the
United
States.
But
what
if
you’re
a
student
and
don’t
have
enough
money
for
a
trip？
Don’t
worry.
Here
are
some
useful
suggestions.
●Save:
This
probably
is
the
most
important
preparation
for
traveling.
Cut
expenses
to
fatten
your
wallet
so
you’ll
have
more
choices
about
where
to
go
and
how
to
get
there.
●Plan
ahead:
Don’t
wait
until
the
last
minute
to
plan
your
trip.
Tickets
may
cost
more
when
bought
on
short
notice.
Giving
yourself
several
months
to
get
ready
can
mean
security(安全)
and
savings.
●Do
your
homework:
No
matter
where
you
go,
research
the
places
you
will
visit.
Decide
what
to
see.
Travel
books
will
provide
information
on
the
cheapest
hotels
and
restaurants.
●Plan
sensibly:
Write
down
what
you
expect
to
spend
for
food
and
hotels.
Stick
to(坚持)
your
plan
or
you
may
not
have
enough
money
to
cover
everything.
●Travel
in
groups:
Find
someone
who
is
interested
in
visiting
the
same
places.
By
traveling
with
others
you
can
share
costs
and
experiences.
●Work
as
you
go:
Need
more
money
to
support
your
trip？
Look
for
work
in
the
places
you
visit.
●Go
off
the
beaten
path:
Tourist
cities
may
be
expensive.
You
may
want
to
rethink
your
trip
and
go
to
a
less-known
area.
Smaller
towns
can
have
many
interesting
activities
and
sights.
●Pack
necessary
things:
The
most
important
things
to
take
are
not
always
clothes:
Remember
medicine
in
case
you
get
sick
and
snacks
in
case
you
cannot
find
a
cheap
restaurant.
●Use
the
Internet:
The
Net
can
help
to
save
money.
Some
useful
websites
include
www.
Travelocity.
com,
www.
Bargains—lowest
fare(票价).
com
and
www.
Economic
travel.
com.
By
planning
sensibly,
even
students
can
enjoy
the
travel.
Your
travel
experiences
will
be
remembered
for
a
lifetime.

The
Ontario
government
is
introducing
several
programs
to
reduce
the
amount
of
material
heading
to
landfills(垃圾场).
The
Ontario
government
is
seeking
public
comment
(评价)
on
new
regulations
that
would
help
municipalities(市政)
and
industry
keep
more
waste
out
of
landfills
and
support
new
waste
technologies.
“Our
goal
is
to
change
the
use
of
more
materials
from
landfill
while
encouraging
new
waste
technologies,”
said
Laurel
Broten,
Ontario’s
Environment
Minister.
“To
that
end,
we
are
working
hard
to
develop
the
tools
that
our
municipal
and
industry
partners
need
to
manage
their
waste
in
the
safest
and
most
environmentally
responsible
way
possible
for
the
21st
century.”
The
government
has
announced
suggested
regulations:
available
for
a
60-day
public
comment
period,
that
focus
on
the
following
key
areas:
Recycling—The
ministry
is
suggesting
regulations
that
would
create
incentives(激励)
by
making
it
easier
for
municipalities
to
increase
recycling,
and
remove
barriers(障碍)
that
make
it
costly
and
/
or
restrictive
for
the
industry
to
recycle.
These
incentives
are
expected
to
encourage
the
recycling
of
batteries,
electronics
and
roof
building
materials.
Alternative
Fuels—The
ministry
is
suggesting
to
remove
the
requirements
for
turning
certain
wastes
into
alternative
fuels
in
order
to
keep
these
wastes
out
of
landfills.
Waste
Technologies—The
ministry
is
suggesting
that
demonstration
projects,
including
energy-from-waste
technologies,
be
removed
from
the
environmental
assessment(估价)
process
and
from
a
required
waste
hearing
for
a
set
period
of
time.
The
ministry
is
also
seeking
comments
and
suggestions
on
ways
to
encourage
product
makers
to
set
up
systems
to
collect
or
accept
spent
products,
such
as
computers
and
other
electronics,
directly
from
consumers.
44.

the
passage,
we
can
infer

in
Ontario
usually
_______.

support
new
waste
technologies
B.
accept
used
computers
and
other
electronics
C.
recycle
waste
very
cheaply
D.
deal
with
waste
by
burying
it
under
the
ground
45.
The
underlined
part
“To
that
end”
in
Paragraph
3
means
“_______”.
A.
To
put
an
end
to
some
old
regulations
B.
To
achieve
the
goal
to
reduce
wastes
for
landfills
C.
At
the
end
of
the
public
comments
D.
Towards
the
end
of
the
assessment
process
46.

“America’s
No.1
Health
Problem.”
So
reads
the
headline
of
an
article
published
by
the
American
Institute
of
Stress
that
claims
the
biggest
threat
to
health
today
is
neither
cancer
nor
AIDS.
The
report
says:
“It
has
been
estimated(估计)
that
75—90
percent
of
all
visits
to
primary
care
physicians
are
for
stress
related
problems.”
It
is
no
exaggeration(夸张)
to
say
that
people
today
are
being
attacked
by
stress.
According
to
the
National
Consumers
League,
“Work
is
the
top
source
of
stress
for
adults
who
have
problems
and
stress
in
their
lives
(39%),
followed
by
family
(30%).
Other
sources
include
health
(10%),
concern
about
the
economy
(9%)
and
concern
about
international
conflict
and
terrorism
(4%).”
However,
stress
is
hardly
unique
to
the
United
States.
A
British
survey
in
2005
estimated
that
“over
half
a
million
individuals
in
Britain
believed
in
2004
that
they
were
experiencing
work-related
stress
at
a
level
that
was
making
them
ill.”
As
a
result
of
“work-related
stress,
depression
or
anxiety,”
there
are
“an
estimated
thirteen
and
a
half
million
reported
lost
working
days
per
year
in
Britain.”
The
picture
is
no
less
bleak(荒凉的)
in
mainland
Europe.
According
to
the
European
Agency
for
Safety
and
Health
at
Work,
“work-related
stress
has
been
shown
to
affect
millions
of
European
workers
across
all
types
of
employment
sectors.”
One
survey
revealed
that
there
are
“about
41
million
workers
affected
by
work-related
stress
each
year.”
What
about
Asia？
A
report
issued
by
a
conference
held
in
Tokyo
concluded:
“Job
stress
is
a
common
concern
among
many
countries
in
the
world,
both
developing
and
industrialized
countries.”
The
report
observed
that
“several
countries
in
East
Asia,
including
China
and
Korea,
have
rapidly
industrialized
and
economically
grown.
These
countries
now
have
a
lot
of
concerns
on
job
stress
and
its
harmful
effects
on
worker
health.”

nationwide
ban(禁止)
on
night
flights
would
reduce
the
aviation(航空)
industry’s
effect
on
the
climate,
a
new
study
shows.
Scientists
have
found
that
the
warming
effect
of
aircraft
is
much
greater
when
they
fly
in
the
dark,
because
of
the
effects
of
the
condensation
contrails(雾化尾迹)
they
leave.
Piers
Forster,
an
environmental
scientist
at
the
University
of
Leeds
who
led
the
project,
said:
“Night
flights
are
twice
as
bad
as
day
flights
for
the
environment.
If
the
government
wanted
to
reduce
the
likely
effect
of
flights
on
climate
then
it
could
ensure
that
more
planes
flew
during
the
day.”
Writing
in
the
journal
Nature
today,
Dr
Forster
and
his
colleagues
say
aircraft
contrails
enhance
the
greenhouse
effect
because
they
absorbed
heat
in
the
same
way
as
clouds.
During
the
day,
their
warming
effect
is
not
serious
because
contrails
reflect
sunlight
back
into
space,
which
helps
to
keep
the
planet
cool.
Dr.
Forster
added:
“Aircraft
currently
only
have
a
small
effect
on
climate.
However,
the
fact
that
the
amount
of
air
traffic
is
set
to
grow
rapidly
in
coming
years
makes
it
important
to
find
out
the
effects
of
contrails
on
our
climate.”
he
said.
The
scientists
monitored(监控)
air
traffic
over
the
UK
and
worked
out
that,
although
one
in
four
flights
occurred
between
6
pm
and
6
am,
they
contributed
60—80%
of
the
warming
that
could
be
attributed
to
contrails.
Winter
flights
had
more
effect
than
those
in
the
summer,
contributing
50%
of
the
warming
despite
providing
only
22%
of
traffic.
52.
Which
is
NOT
the
reason
why
there
should
be
a
nationwide
ban
on
night
flight？
A.
Because
a
nationwide
ban
on
night
flight
can
reduce
the
aviation
industry’s
effect
on
the
climate.
B.
Because
during
the
day
aircraft
contrails
can
drop
the
greenhouse
effect.
C.
Because
a
nationwide
ban
on
night
flight
can
stop
carbon
dioxide
from
being
let
out.
D.
Because
the
warming
effect
of
aircraft
is
much
greater
when
they
fly
in
the
dark.
53.
The
underlined
word
“enhance”
in
the
third
paragraph
means
“______”.
A.
increase
B.
strengthen
C.
drop
D.
reduce
54.
Which
of
the
following
is
NOT
true？
A.
According
to
Dr
Forster’s
words,
aircraft
only
have
small
effect
on
climate
now.
B.
In
the
UK
one
in
four
flights
occurred
between
6
pm
and
6
am,
they
contributed
60-80%
of
the
warming
contrails.
C.
Winter
flights
had
more
effect
than
those
in
the
summer,
contributing
50%
of
the
warming
despite
providing
only
88%
of
traffic.
D.
Some
scientists
think
night
flights
are
twice
as
bad
as
day
fights
for
the
environment.

version:
Dear
headmaster，
Knowing
that
our
school
is
going
to
install
air-conditioners，
the
students
of
our
class
had
a
heated
discussion.
Some
students
are
for
the
plan
while
others
are
against
it.
Students
who
are
for
the
plan
think
that
air-conditioners
can
make
us
comfortable
both
in
summer
and
in
winter.
Besides，
their
families
are
well
off
and
can
afford
the
cost.
But
other
students
think
that
air-condi？鄄tioners
can
make
the
environment
get
worse，
and
air-conditioners
will
make
a
lot
of
noise
which
will
have
a
bad
effect
on
their
studies.
Meanwhile，
installing
air-conditioners
will
increase
their
economic
burden.
In
my
opinion，
I
don’t
agree
to
install
air-conditioners.
We
are
students，
and
we
should
protect
our
environment
as
well.
With
best
wishes.
Yours，
Li
