Ⅰ.完形填空
I'm
sitting
in
a
quiet
hotel
room.
It's
just
past
noon,
late
July,
and
I'm
listening
to
the
__1__
sounds
of
a
life?or?death
struggle
going
on
a
few
feet
away.
There's
a
small
fly
burning
out
the
__2__
of
its
short
life's
energies
in
a
fruitless
attempt
to
__3__
through
the
glass
window.
The
beating
wings
tell
the
moving
story
of
the
fly's
__4__：Try
harder.
But
it's
not
__5__.
The
crazy
effort
offers
no
hope
for
__6__.
Ironically,
the
struggle
is
part
of
the
__7__.
It
is
__8__
for
the
fly
to
try
hard
enough
to
succeed
in
breaking
through
the
glass.
This
fly
is
doomed.
It
will
die
there
on
the
windowsill.
Across
the
room,
ten
steps
away,
the
door
is
__9__.
Ten
seconds
of
flying
time
and
this
small
creature
could
__10__
the
outside
world
it
seeks.
With
only
a
fraction
of
the
effort
now
being
__11__，
it
could
be
free
of
this
self?created
trap.
Why
doesn't
the
fly
try
another
approach,
something
dramatically
__12__？
How
did
it
get
so
__13__
in
the
idea
that
this
particular
route
offers
the
most
promise
for
success?
What
logic
is
there
in
continuing
to
seek
a(n)
__14__
by
repeating
the
same
failed
action?
There
is
no
doubt
that
the
approach
of
“keep
trying
hard”
makes
sense
for
the
fly.
Regrettably,
it's
the
same
idea
that
will
eventually
__15__
the
fly.
Trying
harder
isn't
__16__
the
solution
to
achieving
more.
It
may
not
offer
any
real
__17__
for
getting
what
you
want
out
of
life.
Sometimes,
trying
harder
is
the
problem.
If
you
__18__
your
hopes
for
a
breakthrough
on
trying
harder
than
ever,
you
may
__19__
your
chances
of
success.
You
should
try
harder
by
trying
__20__.

Ⅱ.七选五
Now,
you
may
be
thinking,
“Oh
my
goodness,
how
do
I
start
to
get
better
sleep?
__1__”
Well,
beyond
avoiding
the
damaging
and
harmful
impact
of
alcohol
and
caffeine
on
sleep,
and
if
you're
struggling
with
sleep
at
night,
avoiding
naps
during
the
day,
I
have
two
pieces
of
advice
for
you.
The
first
is
regularity.
Go
to
bed
at
the
same
time,
wake
up
at
the
same
time,
no
matter
whether
it's
the
weekday
or
the
weekend.
Regularity
is
the
king,
and
it
will
stabilize
your
sleep
and
improve
the
quantity
and
the
quality
of
that
sleep.
__2__
Your
body
needs
to
drop
its
core
temperature
by
about
two
to
three
degrees
Fahrenheit
(华氏的)
for
you
to
initiate
sleep
and
then
to
stay
asleep,
and
it's
the
reason
you
will
always
find
it
easier
to
fall
asleep
in
a
room
that's
too
cold
than
too
hot.
So
aim
for
a
bedroom
temperature
of
around
65
degrees,
or
about
18
degrees
Celsius
(摄氏的).
__3__
And
then
finally,
in
taking
a
step
back,
what
is
the
mission
critical
statement
here?
Well,
I
think
it
may
be
this:
sleep,
unfortunately,
is
not
an
optional
luxury.
__4__
It
is
your
life?support
system,
and
it
is
Mother
Nature's
best
effort
yet
at
immortality
(永生).
And
the
decrease
of
sleep
throughout
industrialized
nations
is
having
a
disastrous
impact
on
our
health,
even
the
safety
and
the
education
of
our
children.
__5__
And
it's
fast
becoming
one
of
the
greatest
public
health
challenges
that
we
face
in
the
21st
century.
A．Is
it
a
good
idea
to
stay
up?
B．The
second
is
to
keep
the
body
cool.
C．It's
a
silent
sleep
loss
disease.
D．Sleep
is
a
biological
necessity.
E．What
are
your
tips
for
good
sleep?
F．That's
going
to
be
the
best
option
for
the
sleep
of
most
people.
G．You
can't
update
your
memory
if
you
don't
have
enough
sleep.
睡眠缺乏正迅速成为21世纪威胁公众健康的最大挑战之一。本文就如何睡个好觉提出了两条建议。
1．E
解析：根据空前的“how
do
I
start
to
get
better
sleep”(我怎样才能开始睡得更好)及空后的内容，尤其是“I
have
two
pieces
of
advice
for
you”可知，空处应是询问睡好觉的建议，故E项符合语境，承上启下。
2．B
解析：根据本段的第一句“The
first
is
regularity”及空处下文中的“drop
its
core
temperature”“too
cold”可知，该处应是第二条建议，故B项“第二是保持身体凉爽”符合语境。
3．F
解析：空前一句表述卧室的温度要控制在65华氏度左右，或者大约18摄氏度，由此可知F项“那将是大多数人睡眠的最佳选择”符合语境。
4．D
解析：空前一句表述睡眠并不是一个可选的奢侈品；又根据空后一句“It
is
your
life?support
system,
and
it
is
Mother
Nature's
best
effort
yet
at
immortality
(永生)”可知，D项“睡眠是一个生物必需品”与此处匹配。
5．C
解析：空前一句表述睡眠的减少对我们的健康，甚至对我们孩子的安全和教育都产生了灾难性的影响，空后一句表述它正迅速成为我们在21世纪面临的最大的公共健康挑战之一，故C项“它是一种无声的睡眠缺失疾病”承上启下，符合语境。

for
his
friend
and
himself.

Ⅰ.阅读理解
A
Almost
none
of
us
have
the
time
to
read
everything
we'd
like
to
read.
Yet
we
lose
countless
hours
to
daily
activities
that
bring
us
little
joy
like
taking
buses
and
waiting
in
line.
What
if
we
could
turn
these
little
blocks
of
unoccupied
time
into
precious
and
rewarding
moments
for
learning
and
reflection?
Founded
in
2015,
iReader,
a
micro?learning
app
on
mobile
phones,
brings
the
biggest
ideas
from
best?selling
books
through
15?minute
audio
(音频)
and
text.
So
far,
more
than
3,000
books
have
been
included,
ranging
from
psychology
and
parenting
to
management
and
economics,
with
new
titles
added
every
day.
iReader
is
pioneering
a
new
method
of
reading,
with
over
9
million
users
enjoying
the
benefits
already.
According
to
the
Pew
Research
Center
(PRC),
the
British
read
just
4
paper
books
a
year
and
over
25%
haven't
read
a
single
paper
book
this
year,
but
reading
isn't
dying.
There
are
now
more
ways
for
the
British
to
read
than
ever
before,
due
to
the
widespread
use
of
e?books
and
audio
books.
The
books
in
iReader
are
rewritten
to
ensure
it
is
easy
to
remember
the
main
content.
The
way
the
content
is
edited
has
been
specifically
designed
to
ensure
it
is
useful
in
practice.
Besides,
the
content
is
rewritten
with
relevant
examples
in
real
life,
which
means
users
are
more
likely
to
remember
and
apply
what
is
helpful
to
them.
Co?founder
of
this
app,
declares,
“iReader
gives
you
the
biggest
ideas
in
the
shortest
possible
time.
It
transforms
great
ideas
into
little
packs
you
can
listen
to
or
read
in
just
15
minutes.”

B
When
Jennifer
Powell
heard
her
husband,
Seth
Marko,
43,
needed
immediate
open?heart
surgery
(外科手术),
she
immediately
took
action.
First,
she
found
a
person
to
care
for
their
3?year?old
daughter,
Josephine,
so
she
could
be
at
the
hospital
for
her
husband's
10?hour
surgery.
Then
Powell's
mind
went
to
their
“second
kid”—the
Book
Catapult—the
small
independent
bookstore
the
couple
owns
and
runs.
Their
only
employee
had
the
flu
and
would
be
out
for
at
least
a
week.
Powell
closed
the
store
to
be
with
her
husband
in
the
hospital.
She
didn't
know
for
how
long.
Her
close
friend
Ehrig?Burress
was
watching
Josephine.
But
Ehrig?Burress,
who
runs
another
bookstore
in
town,
wanted
to
help
more.
“We
were
all
sort
of
overwhelmed
(不知所措的)
and
in
shock，”
Ehrig?Burress
said.
He
thought
he
could
help
with
the
Book
Catapult.
He
worked
there
a
few
times
when
his
friends
first
opened
the
store
in
late
2017.
He
still
had
the
keys,
and
he
knew
how
to
work
the
register.
He
could
try
to
keep
it
afloat.
“I
think,
I'll
pretend
this
is
my
store
for
the
week，”
Ehrig?Burress
said.
Julie
Slavinsky,
who
works
at
the
independent
bookstore
Warwick's,
is
also
one
of
the
volunteers
who
helped
out.
She
and
Marko
used
to
work
together
at
Warwick's.
“People
don't
like
to
ask
for
help.
You
have
to
say,
‘Hey,
I
have
a
few
hours.
Do
you
need
me？’”
Slavinsky
said.
Slavinsky
said
although
the
Book
Catapult
is,
strictly
speaking,
a
competitor
to
her
employer,
she
doesn't
see
things
that
way.
“The
book
world
is
a
little
bit
different，”
she
said.
“I
see
this
as
helping
somebody
in
the
community.
It's
the
community
coming
together.”
Powell
said
she
couldn't
offer
enough
thanks
to
all
those
who
had
helped
her
and
her
husband.
本文是记叙文。Jennifer
Powell的丈夫Seth
Marko需要立即进行心脏直视手术，他们得到了别人的帮助。
5．Why
did
Jennifer
Powell
want
to
close
her
bookstore?
A．To
take
care
of
her
daughter.
B．To
attend
to
her
husband.
C．To
raise
money
for
her
husband.
D．To
look
for
new
employees.
答案：B
解析：细节理解题。由第三段第一句“Powell
closed
the
store
to
be
with
her
husband
in
the
hospital”可知，Powell关闭书店是为了去医院照顾生病的丈夫。故选B。
6．What
happened
to
the
Book

Ⅱ.七选五
Make
Your
Fitness
Resolution
Stick
Last
year,
the
most
common
New
Year's
resolution
was
fitness?related.
A
study
showed
that
roughly
50
million
Americans
pledged
(发誓)
to
increase
activities
and
lose
weight.
__1__，
success
was
hard
to
achieve.
Two
months
later,
only
37
percent
of
people
in
their
20s
and
16
percent
over
age
50
had
kept
to
their
new
fitness
habit.
__2__，
the
benefits
of
such
a
change
are
clear.
There
is
no
question
that
exercise
plays
a
role
in
the
prevention
and
treatment
of
many
diseases.
Weekly
exercise
routines
have
been
shown
to
reduce
rates
of
depression
and
anxiety,
lessen
risk
of
heart
attacks
and
strokes,
and
reduce
the
prevalence
of
diabetes.
__3__.
It's
suggested
that
150
minutes
per
week
of
moderate
intensity
exercise
like
swimming,
or
75
minutes
per
week
of
intense
exercise,
like
jogging,
should
be
the
minimum
amount
of
exercise
needed
to
achieve
maximum
medical
benefit.
Often,
the
best
way
to
increase
your
exercise
is
to
incorporate
(包含)
movement
into
your
everyday
life.
On
average,
urban
citizens
who
go
to
work
by
bike
or
public
transportation
are
fitter
than
suburban
citizens
who
drive
to
work.
Besides,
taking
the
stairs
instead
of
the
elevator
also
helps.
__4__.
Whether
you
resolve
to
work
out
at
your
local
gym
three
times
a
week,
take
10,000
steps
a
day
or
give
your
dog
an
extra
walk
every
day,
what
matters
most
is
not
your
commitment
to
exercise
but
your
sticking
to
it.
__5__.
A．While
they
had
good
intentions
B．Although
behavior
change
is
tough
C．However
hard
they
try
to
make
a
change
D．There
is
always
one
type
of
exercise
that
you
are
fond
of
E．So
commit
to
something
you
love
and
keep
to
your
fitness
habit
F．They
are
good
ways
to
increase
the
amount
of
your
movement
every
day
G．The
best
form
of
exercise
is
the
type
that
someone
will
consistently
perform
1．A 解析：根据上文中的“roughly
50
million
Americans
pledged
(发誓)
to
increase
activities
and
lose
weight”可知，大约五千万美国人发誓要增加运动量和减肥；并结合空后的“success
was
hard
to
achieve”(成功很难实现)可知，A项“尽管他们的打算很好”承上启下，符合语境。故选A。
2．B 解析：根据该空后的句子“the
benefits
of
such
a
change
are
clear”(这种改变的好处是很明显的)中的“such
a
change”及语境可知，B项与此处匹配。
3．G 解析：根据该段中的“150
minutes
per
week
of
moderate
intensity
exercise”“75
minutes
per
week
of
intense
exercise”“the
minimum
amount
of
exercise”可知，本段的内容是关于不同的锻炼方式及每周的锻炼时间的。故G项与此处匹配。
4．F 解析：根据本段第一句中的“the
best
way...into
your
everyday
life”可知，本段讲的是增加日常运动量的方法；并结合空前的“go
to
work
by
bike
or
public
transportation”“taking
the
stairs”和“fitter
than”等可推知，这里应是说明这些方法的好处。故F项与此处匹配。
5．E 解析：根据上文中的“what
matters
most
is
not
your
commitment
to
exercise
but
your
sticking
to
it”可知，这里强调的是将锻炼(计划)付诸行动并坚持下去的重要性。这与E项的表述相一致。故选E。
Ⅲ.语法填空
Honeybee
populations
in
the
United
States
__1__
(decrease)
dramatically
over
the
decades.
And
a
new
study
suggests
that
a
certain
kind
of
pesticide
could
be
making
things
__2__
(bad)．
The
number
of
honeybees
hasn't
changed
much
over
the
past
few
years,
but
the
overall
picture
doesn't
look
good
for
an
insect
that
plays
__3__
important
role
in
our
food
supply.
Scientists
don't
know
for
sure
__4__
this
is
happening.
Pesticides
and
parasites
(寄生虫)
are
the
most
suspected
reasons,
according
to
a
study
recently
published
in
the
scientific
journal.
One
suggests
that
neonicotinoids,
types
of
pesticides
that
__5__
(use)
around
the
world,
are
incredibly
poisonous
to
honeybees
and
other
insects.
Part
of
the
reason
for
that
is
that
these
pesticides
appear
__6__
(stick)
around
in
the
environment
and
stay
dangerous
for
longer
periods
of
time.
Though
they're
deadly
to
insects,
neonicotinoids
are
not
considered
dangerous
to
humans.
An
ongoing
challenge
__7__
farmers
is
finding
ways
to
keep
other
insects
away
while
still
__8__
(protect)
bees.
Pesticides
may
not
discriminate
between
the
insects
they
kill,
though
neonicotinoids
makers
say
the
risk
to
bees
is
lower
when
they
are
used
properly.
The
US
Department
of
Agriculture
says
it's
__9__
(likely)
that
there's
one
magic
__10__
(solve)
to
the
problem,
but
there
are
a
number
of
organizations
trying
to
help
honeybees.
几十年来，美国蜜蜂的数量一直在大幅度减少。一项新的研究表明，某种杀虫剂可能会令情况进一步恶化。
1．have_decreased/have_been_decreasing
解析：考查动词的时态和主谓一致。根据句中的时间状语over
the
decades可知，该句应用现在完成时或现在完成进行时；由该句主语Honeybee
populations可知，主语为复数形式，谓语动词也应用复数形式，故填have
decreased或have
been
decreasing。
2．worse
解析：考查形容词的比较级。上文提到几十年来，美国蜜蜂的数量一直在大幅度减少，此处表示某种杀虫剂可能会使情况变得更糟，故填worse。
3．an
解析：考查冠词。play
a
role
in...意为“在……中起作用”，role是可数名词，其定语important的发音以元音音素开头，故填an。
4．why
解析：考查连接词。分析句子结构可知，空处引导宾语从句，作know的宾语；又根据语境可知，此处表示科学家不能确定这一情况发生的原因。空处在从句中作原因状语，故填why。
5．are_used
解析：考查动词的时态、语态和主谓一致。分析句子结构可知，关系代词that指代先行词types
of
pesticides，在从句中作主语，为复数形式，故谓语动词用复数形式；此处描述的为客观情况，应用一般现在时；且use与主语是被动关系，故此处应用被动语态，故填are
used。
6．to_stick
解析：考查动词不定式。appear
to
do
sth.是固定用法，意为“似乎做某事”。此处表示这些杀虫剂似乎会在环境中滞留。
7．for
解析：考查介词。根据语境并分析句子结构可知，此处表示对农民来说一项持续存在的挑战，故填for。
8．protecting
解析：考查现在分词。由空前的从属连词“while”可知，表示“在保护蜜蜂的同时”应用while
they
are
protecting
bees。省略主语和be，故用现在分词形式。
9．unlikely
解析：考查词形转换。根据该句中的“but
there
are
a
number
of
organizations
trying
to
help
honeybees”可知，美国农业部表示，不太可能有一个神奇的解决方案，故填unlikely。
10．solution
解析：考查名词。空前的magic是形容词，修饰名词，其前又有数词one，故此处应用名词单数形式solution。
