When
I
was
thirteen，my
family
moved
from
Boston
to
Tucson，Arizona.
Before
the
move，my
father
__16__
us
in
the
living
room
on
a
freezing
January
night.
My
sisters
and
I
sat
around
the
fire，not
realizing
that
the
universe
would
suddenly
change
its
course.
“In
May，we're
__17__
to
Arizona.”
The
words，so
small，didn't
seem
__18__
enough
to
hold
my
new
life.
But
the
world
changed
and
I
awoke
on
a
train
moving
across
the
country.
I
watched
the
scene
change
from
green
trees
to
flat
dusty
plains
to
high
mountains
as
I
saw
strange
new
plants
that
__19__
mysteries
yet
to
come.
Finally，we
arrived
and
__20__
into
our
new
home.
While
my
older
sisters
were
sad
at
the
loss
of
friends，I
__21__
explored
our
new
surroundings.
One
afternoon，I
was
out
exploring
__22__
and
saw
a
new
kind
of
cactus(仙人掌)．I
crouched
(蹲)
down
for
a
closer
look.
“You'd
better
not
touch
that.”
I
turned
around
to
see
an
old
woman.
“Are
you
new
to
this
neighborhood？”
I
explained
that
I
was，__23__，new
to
the
entire
state.
“My
name
is
Ina
Thorne.
Have
you
got
used
to
life
in
the
__24__？It
must
be
quite
a
shock
after
living
in
Boston.”
How
could
I
explain
how
I
__25__
the
desert？I
couldn't
seem
to
find
the
right
words.
“It's
vastness，”she
offered.
“That
vastness
when
you
stand
on
the
mountains
overlooking
the
desert—you
can
__26__
how
little
you
are
in
comparison
with
the
world.__27__，you
also
feel
that
the
possibilities
are
limitless.”
That
was
it.
That
was
the
feeling
I'd
had
ever
since
I'd
first
seen
the
mountains
of
my
new
home.
Again，my
life
would
change
with
just
a
few
simple
words.
“Would
you
like
to
come
to
my
home
tomorrow？Someone
should
teach
you
which
plant
you
should
and
shouldn't
touch.”

Comprehension
(30

A
If
you
were
to
come
up
with
a
list
of
organizations
whose
failures
had
done
the
most
damage
to
the
American
economy
in
recent
years，you
would
probably
have
to
start
with
the
Wall
Street
firms
that
brought
us
the
financial
crisis.
From
there，you
might
move
on
to
the
automakers
in
Detroit.
But
I
would
suggest
that
the
list
should
also
include
a
less
obvious
nominee：public
education.
At
its
top
level，the
American
system
of
higher
education
may
be
the
best
in
the
world.
Yet
in
terms
of
its
core
mission—turning
teenagers
into
educated
college
graduates—much
of
the
system
is
failing.
The
United
States
does
a
good
job
enrolling(招生)teenagers
in
college，but
only
half
of
the
students
who
enroll
end
up
with
a
bachelor's
degree.
So
identifying
the
causes
of
the
college
dropout
crisis
in
the
world's
largest
economy
matters
enormously，and
a
new
book
called
“Grossing
the
Finish
Line”
tries
to
do
precisely
that.
Its
authors
are
economists
Willian
Bowen
and
Michael
Mcpherson，and
a
doctoral
candidate
Matthew
Chingos.
The
first
problem
they
diagnose
is
something
they
call
undue
matching.
It
refers
to
students
who
choose
not
to
attend
the
best
college
they
can
get
into.
They
instead
go
to
a
less
selective
one，perhaps
one
that
is
closer
to
home
or
less
expensive.
About
half
of
the
low
income
students
with
a
grade
point
average
of
at
least
3.5
in
high
school
and
an
SAT
score
of
at
least
1，200
do
not
attend
the
best
college
they
could
have.
“I
was
really
astonished
by
the
degree
to
which
well
qualified
students
from
poor
families
under
matched，”said
Mr
Bowen.
In
fact，well
off
students
attend
the
colleges
that
do
the
best
job
of
producing
graduates.
Meanwhile，lower
income
students—even
when
they
are
better
qualified—often
go
to
colleges
that
excel(擅长)in
producing
dropouts.
“It's
really
a
waste，”
Mr
Bowen
said，“and
a
big
problem
for
the
country.”
As
the
authors
point
out，the
only
way
to
lift
the
college
graduation
rate
significantly
is
to
lift
it
among
poor
and
working
class
students.
Instead，it
appears
to
have
fallen.
What
can
be
done？Money
is
clearly
part
of
the
answer.
36．Which
of
the
following
would
people
first
think
of
as
a
factor
responsible
for
the
American
financial
crisis
according
to
this
passage？
A．The
government.
B．Public
education.
C．The
Detroit
automakers.
D．The
Wall
Street
firms.
37．What
is
a
big
problem
with
American
higher
education？
A．It
is
hard
to
enroll
enough
students
into
college.
B．Many
colleges
are
experiencing
low
rate
of
graduation.
C．Many
college
students
stay
away
from
classes.
D．It
is
hard
for
many
colleges
to
get
financial
aid
from
the
government.
38．The
title
of
the
book
Crossing
the
Finish
Line
probably
means
________.
A．running
to
the
end
of
the
line
B．going
to
college
C．finishing
college
education
D．working
hard
in
college
39．Why
do
some
students
under
match？
A．Because
they
have
financial
difficulty.
B．Because
they
face
ambition
crisis.
C．Because
they
lack
confidence.
D．Because
they
can't
get
guidance.
40．The
passage
is
mainly
about
________.
A．problems
with
secondary
American
education
and
possible
solutions
B．America's
financial
crisis，its
cause
and
influence
C．low
rate
of
American
college
graduation，its
cause
and
its
influence
D．relationship
between
American
education
and
its
economy

There
is
no
doubt
that
to
study
abroad
gives
you
an
excellent
opportunity
to
learn
things
which
are
very
helpful
in
your
career
building.
Today，Canada
has
earned
a
good
name
in
providing
quality
education
and
safe
healthy
environment
for
its
students.
That
is
why
more
than
130，000
international
students
enroll
every
year
in
famous
Canadian
universities.
It
is
an
ideal
education
destination
and
gives
students
a
unique
experience
of
education
and
its
versatile(多样的)arts
and
culture.
Canada
spends
a
lot
on
education
and
is
ranked
the
highest
in
G?8
countries.
To
study
in
Canada
is
very
cost
effective.
These
universities
are
affordable
compared
to
other
universities
in
the
world
such
as
in
the
US，New
Zealand
and
UK
where
cost
of
education
and
living
is
very
high.
According
to
a
survey
in
2006，“Canada
offered
the
lowest
tuition
fees
for
foreign
students
compared
to
UK
and
Australia.”
The
low
rate
of
crimes
and
the
peaceful
safe
environment
of
the
country
also
attract
lots
of
international
students
to
Canadian
universities.
Canada
has
92
universities
and
175
community
colleges
and
university
degrees
have
three
levels—Bachelor's，master's
and
Doctoral.
A
Bachelor's
degree
in
Canada
is
for
three
or
four
years'
full
time
study
depending
upon
the
nature
of
the
program
you
are
doing.
On
the
other
hand，a
Master's
degree
consists
of
two
years
of
study.
For
a
Doctoral
program
in
Canadian
university，you
require
a
minimum
of
three
to
four
or
sometimes
five
years
of
research
and
study.
You
can
also
find
many
diploma
and
certification(认证)programs
in
Canadian
universities
where
the
time
is
generally
one
year.
Some
of
the
Canadian
universities
are
well
regarded
worldwide
and
the
degree
and
diploma
obtained
from
these
Canadian
universities
are
recognized
globally
and
promise
bright
future.
After
the
completion
of
studies，a
person
could
also
find
great
job
offers
in
Canada
itself.
International
students
require
a
work
permit
to
work
on
campus.
41．We
can
learn
from
the
passage
that
________.
A．Canada
has
92
community

for
the
passage？
A．Canadian
culture
B．The
life
in
Canada
C．Benefits
of
studying
abroad
D．Study
in
Canada—a
unique
experience
C
School
life
is
one
of
the
most
important
periods
in
the
life
of
man.
It
is
also
the
most
dreadful.
This
is
because
the
educational
system
is
based
only
on
marks
and
is
very
competitive.
In
the
past，exams
were
held
to
help
the
teacher
know
how
far
a
student
had
understood
the
subject.
Now，they
are
held
to
test
how
far
a
student
can
remember
the
notes.
There
is
no
value
for
the
student
who
has
understood
the
subject.
Value
is
given
only
to
the
student
who
is
able
to
reproduce
the
answer
word
by
word.
The
present
educational
system
brings
a
great
pressure
on
the
students.
The
teachers
and
parents
aid
in
increasing
the
pressure.
Teachers
give
students
loads
of
homework
simply
because
writing
twice
is
equal
to
reading
ten
times.
It
is
true
but
how
can
a
child
complete
the
homework
of
all
five
subjects
in
one
day？
Parents_want_to_live_their_life_through_their_kids.
They
send
the
child
to
dozen
classes
just
because
they
were
not
able
to
learn
dance
&
music，swimming
&karate，but
it
doesn't
mean
that
the
child
has
to
learn
all
these
things
in
their
place.
They
want
their
kids
to
excel
(擅长)
in
everything.
They
also
compare
them
to
other
students.
The
usual
dialogue
in
a
house
is
“Mr
X's
daughter
has
scored
98.64%
and
you
have
just
scored
97.03%！”
They
don't
realize
that
by
saying
such
things
they
discourage
the
child.
Students
are
also
human
beings.
They
also
have
the
same
feelings
as
others.
They
also
need
a
break
from
their
work.
Too
much
reading
can
affect
their
brain
too.
When
the
brain
is
not
able
to
store
all
the
information
fed
into
it，it
stops
storing
more
data.
This
again
leads
to
poor
marks
in
the
exams.
46．Which
of
the
following
is
a
problem
of
the
present
educational
system
mentioned
in
the
text？
A．It
asks
students
to
answer
questions
orally.
B．It
values
students'
correct
notes
in
class.
C．It
requires
students
to
understand
the
subjects.
D．It
pays
much
attention
to
students'
marks.
47．The
underlined
sentence
in
the
fifth
paragraph
shows
that
________.
A．parents
want
to
live
with
their
children
forever
B．parents
want
their
children
to
realize
their
dreams
C．parents
want
to
live
a
better
life
through
their
children
D．parents
want
their
children
to
live
a
better
life
48．Some
parents
compare
their
children
with
others，which
will
________.
A．make
their
children
hate
others
B．cause
their
children
work
harder
C．make
their
children
lose
heart
D．improve
their
children's
self
confidence
49．The
last
paragraph
probably
suggests
that
________.
A．different
students
also
have
the
same
feelings
B．a
lot
of
reading
leads
to
poor
marks
in
the
exams
C．poor
exam
marks
result
from
too
much
reading
D．much
pressure
causes
low
learning
efficiency
50．By
writing
the
text，the
writer
tells
us
that
________.
A．homework
is
a
load
to
students
B．the
life
of
students
is
colorful
C．students
have
too
much
pressure
D．school
life
is
very
important
A
high
school
track
star
in
the
beach
town
of
Ventura，Woodburn
was
once
sidelined
for
months
with
foot
injuries.
“I
started
thinking
about
all
the
things
I
got
from
running—the
health
benefits，the
friendships，the
confidence，”
he
says.
“And
I
realized
there
are
children
who
don't
even
have
shoes.”
Woodburn
gathered
up
his
own
slightly
worn
sneakers，then
put
out
a
call
to
teammates.
His
goal
was
to
have
100
pairs
by
Christmas
2006.When
the
count
climbed
to
more
than
500
pairs(“everything
snowballed，”
he
says)，he
decided
to
turn
the
shoes
drive
into
a
year
round
effort.
Back
then，the
sneakers
came
from
donation
boxes
and
the
local
sporting
goods
store
and
from
door
to
door
pickups.
Woodburn
has
now
set
up
collection
boxes
at
two
high
schools
and
area
race.
To
date，S.O.S.
has
collected
and
donated
more
than
3，000
pairs.
In
just
under
three
years，Woodburn
has
started
three
chapters
of
Share
Our
Soles：the
original
in
Ventura，another
at
USC，and
one
at
the
College
of
the
Holy
Cross
in
Massachusetts
last
January，when
a
student
there
wrote
asking
to
get
involved.
The
organization's
website，shareoursoles.org，keeps
and
distributes
sneakers
and
sells
wrist
bands
and
socks(the
money
earned
from
that
go
toward
new
shoes
and
socks

综合检测
1．C　考查有关动词在语意和使用上的区别。句意：——你怎么没买黄油？——我打算买但是忘记了。mean的过去式为meant，在此处意为“打算”。
2．B　四个动词短语的主要含义：carry
on“继续”；feed
on“吃，以……为食”；put
on“上演，穿/戴上”；focus
on“聚焦于”。句意：蝴蝶以花卉产生的一种甜甜的液体为食，蜜蜂和别的昆虫则采集这种液体。根据句意选B，表示“吃，以……为食”。
3．A　本题含有“leave＋宾语＋宾补”结构，分词和不定式都可作该结构的补语；根据句意知此处应为“使某人感到不满意的”，故应用过去分词形式的形容词unsatisfied作补语。
4．B　考查时态。根据句意，“告诉”这一动作还未发生，应用一般将来时。D项是be
to
do
sth.结构，表示按照计划安排要发生的事，不合语境。
5．A　考查as引导的方式状语从句。as连接方式状语从句时表示“正如……”。
6．B　句意：为了确保博物馆里的文物保存完好，西藏文化保护协会采用了现代技术来监测文物的情况。apply运用，使用；adapt使适应，改编；appoint任命，指定，约定；abolish废止，革除。
7．C　考查regular用作形容词作定语的用法。句意：护士每隔一定的时间给这个病人量血压。故选C。
8．A　句意：在伦敦一些地方，错过一辆车就意味着再等一小时。mean
doing
sth.“意味着什么”；mean
to
do
sth.“打算做什么”。
9．B　as为关系代词，引导一个非限制性定语从句，指代主句整个内容。若用it，则：It
is
known
to
everybody
that
she
is...。
10．B　take
up“开始从事”。句意：为了放松一下，他最近开始下象棋。take
on“穿上，呈现”；hold
on“握住”；hold
up“阻碍”。
11．B　句意：——我收到的这件T恤衫和网页上展示的不一样。——怎么会呢？不过我向您保证我们会立刻查清楚的。Who
says谁说的；How
come怎么会(表达说话人的惊讶之情)；What
for为什么；Why
worry为什么担心。这段对话是关于网购的，发生在买家和客服之间，根据答语中的But可知客服对于买家反映的情况表示惊讶，但还是承诺会查清楚。
12．C　考查非谓语动词。句意：车内安装了显示确切位置的电子地图后，司机就可以朝正确的目的地方向行驶了。fixed
in
the
car
与
showing
the
exact
position
都是宾语补足语，修饰
the
electric
map。the
electric
map与
fix
是被动关系；the
electric
map与showing
the
exact
position
之间是主动关系。
13．B　句意：我们想说些什么，但是她不听任何解释。however在此用作副词。
14．A　furnish...with...用……装备……，符合句意。instructs“引导”；admits“承认”；quits“放弃”，均不合句意。
15．C　考查让步状语从句。句意：无论他回来的有多晚，他母亲都是等着他一块吃晚饭。however作连词，引导让步状语从句。
16．A　父亲把一家人集中在客厅里，进行搬家前的动员。gather
表示“聚集，靠拢”，hurt、beat、hit
都表示打，根据下文，父亲并没有惩罚孩子们。
17．B　根据下文“I
awoke
on
a
train
moving
across
the
country”可知作者一家搬家了。
18.
C　big
在此处指父亲话的分量大小程度，照应了
small。
19．A　因为只有作者对新事物的陌生，才有好奇的探究。familiar表示“熟悉的”；vivid“生动的”，不代表
mysterious
yet
to
come。
20．A　经过漫长的火车之旅，作者一家终于安居新家。settle
in
意为live
in“定居”。
21．D　从下文可以知道他对周围的环境充满好奇，所以很容易理解作者当时的心情，eagerly
表示“急切地”。bitterly“痛苦地”；easily“容易地”；proudly“自豪地”，均不符合题意。
22．B　因为刚刚移居一个新环境，因而活动就比较频繁。as
usual
表示“像往常一样”，符合题意。as
well“也”；right
away
“立刻，马上”；on
time
“按时”。
23．B　in
fact
在这里强调他对新的环境比较陌生。in
fact“事实上”；at
most“至多”；at
least“至少”；at
best
则表示“充其量”。
24．A　根据下文“How
could...the
desert”很显然他们是在沙漠里进行的对话。
25．A　根据下文vastness，可以判断作者不知道用什么词来描绘沙漠，这里考查了句型
How
do
you
find
something？(你觉得……怎么样？)
26．C　根据下文“you
also
feel
that”可以知道置身于茫茫沙漠中，才会有那种心灵的感受。prove
“证明”；guess
“猜”；expect
“期望”。
27．D　also
表示他的感受有两个方面，所以选表示并列的连词
meanwhile，而
thus，otherwise都表示转折，therefore
表示前因后果。
28．to　29.that/which　30.into　31.and
32．on　33.there　34.such　35.the
36．D　细节理解题。由第一段第一句．..you
would
probably
have
to
start
with
the
Wall
Street
firms
that
brought
us
the
financial
crisis.可知答案。
37．B　细节理解题。由第四段可知许多大学中获得学士学位的毕业生仅仅占一半，故答案选B。
38．C　词义猜测题。由第五段第一句可知通过
Crossing
the
Finish
Line
这本书可以了解美国大学生辍学的原因。所以“Grossing
the
Finish
Line”的意思应该是完成大学教育。
39．A　推理判断题。由第五段和第六段可知一些贫困家庭的学生因为经济问题没有上他们能上的最好的大学，而上一些辍学率高的大学。由此可推知A项正确。文中没有和B、C、D选项相关的信息。
40．C　主旨大意题。分析全文不难看出文章主要描述了美国大学低毕业率的状况，分析了其中的原因以及对美国经济的影响，故答案为C。A项中的secondary
American
education(美国的中等教育)错误，B项与主题无关，D项不是文章的主旨。
41．B　细节理解题。根据文章第二段的“Canada
offered
the
lowest
tuition
fees
for
foreign
students
compared
to
UK
and
Australia.”可知答案。
42．C　推理判断题。根据文章第四段可知完成学士学位最少需要3年时间、硕士学位2年、博士学位最少3年，加起来共是8年。
43．D　细节理解题。文章提到了去加拿大留学的许多好处，如教学质量高、环境安全、工作前景好等，但没有提到奖学金的情况。
44．A　作者态度题。从全文看，作者对去加拿大留学持肯定态度。
45．D　主旨大意题。本文主要介绍了一些在加拿大留学的好处。
46．D　从第一段的“the
educational
system
is
based
only
on
marks”可知现在的教育只重视学生的分数，所以D项符合题意。
47．B　结合后面的“they
were
not
able
to
learn
dance
&
music，swimming
&
karate，but
it
doesn't
mean
that
the
child
has
to
learn
all
these
things
in
their
place.”可知父母因为没有机会学会自己喜欢的东西，所以把希望寄托在孩子身上，希望通过他们来实现自己的愿望。因此选B项。
48．C　从倒数第二段的“...they
discourage
the
child”可知拿自己的孩子与其他孩子作比较会使自己的孩子灰心丧气。
49．D　结合最后一段的“When
the
brain
is
not
able
to
store
all
the
information
fed
into
it，it
stops
storing
more
data.
This
again
leads
to
poor
marks
in
the
exams.”可知大脑的承受能力是有限的，书看多了就会适得其反，大脑就停止存储信息了，反而会影响考试成绩，所以选D项。
50．C　本文主要介绍了现代教育制度给学生们带来的压力——考试分数的压力、作业的压力、父母的期望造成的压力等等，所以C项正确。
