Ⅰ.阅读理解
A
We
get
it:You’re
tired.You’re
busy.And
your
shoes
are
way
over
there.Excuses
are
OK
sometimes,but
not
every
day—and
especially
not
today.So
put
on
your
sneakers,get
up
off
the
couch,and
let
us
kick
your
excuses
to
the
curb(路牙子).
“I...dislike...panting(气喘)!”
Being
really
out
of
breath
may
mean
you’re
trying
too
much
too
soon,which
will
kill
your
confidence.But
you
don’t
have
to
be
huffing
and
puffing
to
get
a
workout.Active
doesn’t
have
to
mean
high-intensity(高强度).It’s
just
about
moving.
“I
hate
exercise.”
It
may
seem
unbearable,but
you
just
have
to
get
started.Exercise
releases
endorphins
(your
brain’s
own
feel-good
chemicals),which
can
be
habit-forming.What’s
the
best
exercise The
one
you’ll
do
regularly.So
you
may
hate
running.Don’t
run!Ride
your
bike
or
just
dance.Even
cleaning
your
room
is
active.As
long
as
you’re
moving
and
getting
your
blood
pumping,it
counts.So
get
creative.
“I
don’t
have
time.”
You
may
not
have
lots
of
time
to
spare
when
you’re
busy
with
schoolwork,but
we
bet
you
can
find
10
minutes.Bonus:An
activity
break
will
send
oxygen
to
your
brain,making
you
super-alert(超级警觉的)
and
more
creative
too.Famous
thinkers
like
Aristotle
and
Steve
Jobs
liked
“walking
meetings,”and
you
can
follow
in
their
footsteps
by
moving
around
while
you
brainstorm
about
a
tough
task
or
memorize
your
English
vocabulary.
“I
never
see
results!”
Even
if
you
train
with
the
help
of
a
professional,you
won’t
see
results
right
away.But
you
will
feel
them
almost
immediately.Don’t
focus
on
how
your
body
looks—focus
on
how
you
feel.Keep
a
journal
of
when
you
exercise(or
don’t)
and
how
you
feel
that
day:Stressed Focused Tired When
you
start
noticing
the
amazing
effects
of
exercise,you’ll
have
no
excuses.
【语篇导读】本文是议论文。文章反驳了几种不运动的借口。
1.The
underlined
part
“huffing
and
puffing”
in
Paragraph
2
can
be
replaced
by
“　　　”.
A.moving
around　　　　　　B.breathing
heavily
C.feeling
confident
D.wearing
nice
shoes
答案:B
解析:词义猜测题。由上文的“I...dislike...panting(气喘)!”及“Being
really
out
of
breath
may
mean
you’re
trying
too
much
too
soon...”以及下文的high-intensity可推断,画线部分意思是“气喘吁吁”。
2.In
the
author’s
eyes,the
best
exercise
is
the
one
that
　　　.
A.is
very
relaxing
B.you
will
stick
to
C.produces
good
results
D.you
can
spare
time
on
答案:B
解析:细节理解题。由第三段中的“What’s
the
best
exercise The
one
you’ll
do
regularly.”可知,作者建议人们做任何自己能够坚持下去的运动项目。
3.Steve
Jobs
is
mentioned
to
prove
that
doing
exercise
　　　.
A.is
good
for
one’s
figure
B.is
good
for
one’s
health
C.makes
one
much
happier
D.makes
one
more
productive
答案:D
解析:推理判断题。由第四段中的“...making
you
super-alert(超级警觉的)
and
more
creative
too.”及“Steve
Jobs
liked
‘walking
meetings,’and
you
can
follow
in
their
footsteps
by
moving
around
while...”可推断,乔布斯的例子是为了证明做运动可以使人们的工作效率更高。
4.Which
of
the
following
can
be
the
best
title
for
the
text
A.Exercise
excuses
we
are
not
buying
B.Benefits
of
regular
physical
activity
C.The
best
exercise
and
fitness
routines
D.How
to
get
started
with
an
exercise
plan
答案:A
解析:主旨大意题。通读全文可知,文章列了四个不运动的借口并逐一反驳。故A项最适合作本文的标题。
B
I
always
pictured
myself
graduating
from
college,getting
a
cool
job
and
even
having
a
cute
little
place
of
my
own.So
far,I
have
a
master’s
degree
and
the
coolest
job
ever
as
a
physician
assistant.But
instead
of
waking
up
in
a
pretty
apartment,I
hear
the
early-morning
sound
of
my
parents
making
coffee
downstairs.
At
27,I
still
live
with
my
parents,and
I
love
it.
My
decision
to
live
at
home
was
not
one
of
absolute
necessity.As
a
physician
assistant,I
make
a
good
salary
and
would
be
able
to
live
on
my
own
comfortably
if
I
needed
to
do
so.By
the
time
I
finished
graduate
school,I
had
had
a
$150,000
debt
from
both
undergraduate
and
graduate
education.With
several
of
these
loans
earning
a
7.9%
interest
rate,my
father
calculated
that
my
loans
were
increasing
by
$15
a
day
in
interest
alone.At
this
rate,it
would
take
me
30
years
to
pay
off
my
student
loans,with
much
of
the
payment
going
straight
to
interest.At
last,I
decided
to
live
with
my
parents.
Beyond
the
endless
supply
of
home-cooked
meals,the
best
thing
about
moving
back
home
is
that
I
am
not
alone.Several
of
my
physician
assistant
friends
are
in
the
same
boat
as
I
am—we
are
all
highly
educated,white-collar
employees
who
live
at
home.Our
co-workers
in
the
medical
field
think
it
is
a
great
idea
because
many
of
them
are
facing
the
same
piles
of
debt.They
often
say
if
they
could
do
it
all
again,they
would
do
the
same
thing.
There’s
a
stigma(耻辱)
that
comes
along
with
this
arrangement.Some
people
might
assume
that
we
are
too
lazy
to
find
a
job.I
don’t
think
my
neighbors
understand
it,as
they
continually
ask
me
when
I
am
going
to
graduate
and
if
I
am
old
enough
to
look
after
their
children.My
mom
just
tells
them
that
I’m
successful,well-educated
and
that
I
save
lives.
I
love
living
at
home.Now
I’ve
paid
off
$68,000
of
my
student
loans.Our
new
relationship
is
symbiotic(共生的).My
parents
benefit
from
having
an
extra
set
of
hands
around
the
house
to
help
with
housework
and
a
constant
source
to
explain
all
pop-culture
references.
【语篇导读】本文是记叙文。文章讲述了作者毕业后和父母住在一起的故事。
5.The
author
once
imagined
　　　.
A.having
her
own
beautiful
house
B.having
her
parents
pay
off
her
loans
C.living
with
her
parents
after
graduation
D.always
being
taken
care
of
by
her
parents
答案:A
解析:细节理解题。由第一段开头的“I
always
pictured
myself...even
having
a
cute
little
place
of
my
own.”可知答案为A项。
6.Why
did
the
author
decide
to
live
with
her
parents
A.Because
she
missed
them
very
much.
B.Because
she
couldn’t
cook
by
herself.
C.Because
she
needed
to
repay
a
huge
debt.
D.Because
she
was
not
able
to
support
herself.
答案:C
解析:细节理解题。由第三段可知,作者为读本科和研究生欠下了利息高昂的巨额债务,为尽快偿还贷款,她决定和父母住在一起。
7.What
is
the
author’s
co-workers’
attitude
towards
her
living
with
her
parents
A.Critical.
B.Approving.
C.Doubtful.
D.Uninterested.
答案:B
解析:推理判断题。由第四段末的“Our
co-workers
in
the
medical
field
think
it
is
a
great
idea...they
would
do
the
same
thing.”可推断,作者的同事赞成她和父母住在一起。
8.The
author’s
neighbors
ask
her
to
look
after
their
kids
mainly
because
　　　.
A.they
know
she
is
a
helpful
lady
B.they
know
she
is
well-educated
C.they
think
she
doesn’t
have
a
job
D.they
think
she
is
popular
with
kids
答案:C
解析:推理判断题。由倒数第二段中的“Some
people
might
assume
that
we
are
too
lazy
to
find
a
job.I
don’t
think
my
neighbors
understand
it...”可推断,邻居们让作者照顾孩子是因为他们以为作者是因为没有工作才住在父母的家里。
Ⅱ.七选五
Don’t
scratch
that
itch!
Got
an
itch(痒) 1.　　　
Scratching
an
itch
can
make
it
worse
and
now
scientists
know
why.Researchers
at
Washington
University
School
of
Medicine
in
St.Louis
have
discovered
that
scratching
causes
the
brain
to
produce
a
chemical
called
serotonin(血清素),which
makes
the
itching
more
intense(强烈的).
Scientists
have
long
known
that
scratching
causes
a
mild
sensation(感知)
of
pain
in
your
skin.2.　　　
Yet
pain
signals
that
travel
to
your
brain
relieve
the
itching
only
temporarily.The
problem,says
researcher
Zhou-Feng
Chen,is
that
when
the
brain
receives
those
pain
signals,it
produces
serotonin
to
help
control
the
pain.When
serotonin
travels
along
the
spinal
cord(脊髓),it
can“jump
tracks,”moving
from
pain-sensing
nerve
cells
to
those
that
influence
itch
intensity.3.
Although
Chen
conducted
his
study
on
mice,the
same
annoying
cycle
of
itching
and
scratching
is
thought
to
occur
in
humans.4.
Not
exactly,says
Chen.Serotonin
is
a
neurotransmitter(神经传递介质).It
is
involved
in
growth,aging,and
mood
regulation.Blocking
serotonin
would
have
far-reaching
effects
throughout
the
body,Chen
explains.
The
researchers
are
looking
for
other
ways
to
break
the
cycle
so
they
can
help
people
with
itchy
conditions.One
possibility:Affecting
the
communication
between
serotonin
and
the
nerve
cells
that
transmit
the
itchy
sensation.5.　　
A.Try
to
resist
scratching
it.
B.Until
then,try
not
to
scratch!
C.This
pain
masks
the
itchy
feeling.
D.The
result:The
itch
will
be
more
and
stronger.
E.So
can
blocking
serotonin
make
you
itch-free
F.If
the
itch
is
really
bothering
you,talk
to
your
doctor.
G.Scientists
discover
why
scratching
an
itch
can
make
it
worse.
答案与解析:
【语篇导读】本文是说明文。文章解释了挠痒痒会越挠越痒的原因。
1.A　解析:A项与上文的“Got
an
itch ”相呼应,并且下文的“Scratching
an
itch
can
make
it
worse...”与A项是因果关系。
2.C　解析:C项与上文的“causes
a
mild
sensation
of
pain”及下文的“Yet
pain
signals
that
travel
to
your
brain
relieve
the
itching
only
temporarily.”相呼应。
3.D　解析:根据第一段末的“serotonin,which
makes
the
itching
more
intense”及此空前的“serotonin...moving
from
pain-sensing
nerve
cells
to
those
that
influence
itch
intensity”可推断,挠痒痒的结果是使血清素从有痛感的神经细胞转移到影响痒的强度的神经细胞,从而使人感觉更痒。故D项正确。
4.E　解析:E项与下文的“Not
exactly,says
Chen.Serotonin
is
a
neurotransmitter(神经传递介质).It
is
involved
in
growth,aging,and
mood
regulation.Blocking
serotonin
would...”相呼应。
5.B　解析:B项与上文的“The
researchers
are
looking
for
other
ways
to
break
the
cycle
so
they
can
help
people
with
itchy
conditions.One
possibility...”相呼应。
