In
the
United
States
t
( http: / / www.21cnjy.com )here
was
an
unusual
tale
telling
of
the
daughter
of
a
mechanic
（技工）.
One
day
while
walking
along
the
bank
of
a
lake,
the
girl
1
to
see
20
eggs
laid
by
a
wild
goose（鹅）.
After
some
time
the
girl
2
the
mother
would
not
return
to
her
eggs
and
she
3
to
take
them
home.
There
she
carefully
4
the
eggs
in
the
heat
of
a
lamp.
Several
days
5
the
eggs
broke
and
the
baby
geese
came
into
the
6
.
Geese
are
kno
( http: / / www.21cnjy.com )wn
to
take
the
first
living
thing
they
see
as
their
mother.
7
,
to
these
young
geese,
the
girl
was
their
mother.
As
they
8
,
the
girl
was
able
to
9
her
birds
to
run
across
the
grass,
but
she
could
not
teach
them
to
10
.
The
girl
became
increasingly
worried
about
this,
both
when
11
and
in
her
dreams.
Later,
she
had
an
12
:
She
would
pilot(驾驶)
a
plane
to
guide
them
in
13
.
She
asked
her
father
for
a
plane
and
he
assembled（组装）a
small
aircraft
for
her.
Caring
about
14
safety,
the
father
decided
to
pilot
the
plane
himself.
However,
the
birds
did
not
15
or
follow
him,
and
16
slept
in
the
grass.
One
day,
the
girl
( http: / / www.21cnjy.com )
17
into
the
plane,
started
it
and
soon
left
the
18
.
Seeing
their
mother
take
to
the
air,
the
birds

flapped（拍打）their
wings
and

阅读下列短文,
从给的四个选项
(A、B、C和D)
中,
选出最佳选项。
She
is
widely
seen
as
( http: / / www.21cnjy.com )
proof
that
good
looks
can
last
forever.But，at
nearly
500
years
of
age，time
is
catching
up
with
the
Mona
Lisa.
The
health
of
the
( http: / / www.21cnjy.com )famous
picture，painted
by
Leonardo
da
Vinci
in
1505，is
getting
worse
by
the
year，according
to
the
Louvre
Museum
where
it
is
housed.
“The
thin，wooden
panel
( http: / / www.21cnjy.com )
on
which
the
Mona
Lisa
is
painted
in
oil
has
changed
shape
since
experts
checked
it
two
years
ago.”the
museum
said.Visitors
have
noticed
changes，but
repairing
the
world's
most
famous
painting
is
not
easy.Experts
are
not
sure
about
the
materials
the
Italian
artist
used
and
their
current(现在的)chemical
state.
Nearly
6
milli
( http: / / www.21cnjy.com )on
people
go
to
see
the
Mona
Lisa
every
year，many
attracted
by
the
mystery
of
her
smile.“It's
very
interesting
that
when
you'
re
not
looking
at
her，she
seems
to
be
smiling，and
then，you
look
at
her
and
she
slops.”said
Professor
Margaret
Livingstone
of
Harvard
University.“It'
s
because
direct
vision(视觉)is
excellent
at
picking
up
detail，but
less
suited
to
looking
at
shadows.Da
Vinci
painted
the
smile
in
shadows.”
However，the
actu
( http: / / www.21cnjy.com )al
history
of
the
Mona
Lisa
is
just
as
mysterious
as
the
smile.Da
Vinci
himself
loved
it
so
much
that
he
always
carried
it
with
him，until
it
was
eventually
sold
to
France's
King
Francis
I
in
1519.
In
1911，the
painting
( http: / / www.21cnjy.com )
was
stolen
from
the
Louvre
Museum
by
a
former
employee，who
took
it
out
of
the
museum
hidden
under
his
coat.He
said
he
planned
to
return
it
to
Italy.The
painting
was
sent
back
to
France
two
years
later.
During
World
War
II
( http: / / www.21cnjy.com )，French
men
hid
the
painting
in
small
towns
to
keep
it
out
of
the
hands
of
German
forces.
Like
many
old
lad
( http: / / www.21cnjy.com )ies，the
Mona
Lisa
has
some
interesting
stories
to
tell.
1．The
underlined
( http: / / www.21cnjy.com )
sentence
in
the
first
paragraph
means
the
Mona
Lisa________.
A．is
losing
its
value
B．is
being
damaged
after
so
many
years
C．is
getting
more
valuable
with
years
passing
D．will
rot
away
2．The
smile
of
the
Mona
Lisa
can
only
be
seen________.
A．by
indirect
vision
B．at
a
distance
C．by
direct
vision
D．in
shadows
3．From
the
last
paragraph，we
can
infer
that________.
A．many
interesting
stories
have
been
written
about
the
Mona
Lisa
B．people
are
interested
in
the
stories
about
the
Mona
Lisa
C．some
mysteries
still
remain
to
be
solved
about
the
Mona
Lisa
D．many
more
stories
will
be
told
about
the
Mona
Lisa
4．Experts
haven't
had
any
repairs
on
the
Mona
Lisa
because________.
A．it
is
now
in
a
poor
chemical
state
B．they
don't
know
how
to
replace
the
wooden
panel
C．they
don't
have
the
materials
Da
Vinci
used
D．they
are
afraid
it
will

阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
The
need
to
feed
a
( http: / / www.21cnjy.com )growing
population
is
putting
much
pressure
on
the
world’s
supply
of
water.
With
97%
of
the
world’s
water
too
salty
to
be
drunk
or
used
in
agriculture,
the
worldwide
supply
of
water
needs
careful
management,
especially
in
agriculture.
Although
the
idea
of
a
water
shortage
(短缺)
seems
strange
to
someone
fortunate
enough
to
live
in
a
high
rainfall
country,
many
of
the
world’s
agricultural
industries
experience
constant
water
shortages.
Although
dams
can
( http: / / www.21cnjy.com )
be
built
to
store
water
for
agricultural
use
in
dry
areas
and
dry
seasons,
the
costs
of
water
redistribution
(重新分配)
are
very
high.
Not
only
is
there
the
cost
of
the
engineering
itself,
but
there
is
also
an
environmental
cost
to
be
considered.
Where
valleys
(山谷)
are
flooded
to
create
dams,
houses
are
lost
and
wildlife
homes
destroyed.
Besides,
water
may
flow
easily
through
pipes
to
fields,
but
it
cannot
be
transported
from
one
side
of
the
world
to
the
other.
Each
country
must
therefore
rely
on
the
management
of
its
own
water
to
supply
its
farming
requirements.
This
is
particular
( http: / / www.21cnjy.com )ly
troubling
for
countries
with
agricultural
industries
in
areas
dependent
on
irrigation
(灌溉).
In
Texas,
farmers’
overuse
of
irrgation
water
has
resulted
in
a
25%
reduction
of
the
water
stores.
In
the
Central
Valley
area
of
southwestern
USA,
a
huge
water
engineering
project
provided
water
for
farming
in
dry
valleys,
but
much
of
the
water
use
has
been
poorly
managed.
Saudi
Arabia’s
atte
( http: / / www.21cnjy.com )mpts
to
grow
wheat
in
desert
areas
have
seen
the
pumping
of
huge
quantities
of
irrigation
water
from
underground
reserves.
Because
there
is
no
rainfall
in
these
areas,
such
reserves
can
only
decrease,
and
it
is
believed
that
fifty
years
of
pumping
will
see
them
run
dry.

the
first
two
paragraphs
we

that　　　.　
A.
much
of
the
world’s
water
is
available
for
use
B.
people
in
high

countries
feel
lucky
C.
the
costs
of
water
redistribution
should
be

2.
Which
of
the

stores
in
Texas
have
been

by
75%.
B.
Most
industries
in
the
world
suffer
from
water
shortages.
C.
The
underground
water
in
Saudi
Arabia
might
run
out
in
50
years.
D.
Good
mana

of
water
use
resulted
from
the
project
in
the
Central

Businesses
a
( http: / / www.21cnjy.com )re
witnessing
a
difficult
time,
which
has
in
turn
produced
influence
on
consumers’
desire
to
go
green.
However,
shoppers
are
still
laying
stress
on
environmental
concerns.
Two
thirds
of
cus
( http: / / www.21cnjy.com )tomers
say
that
environmental
considerations
inform
their
purchases
to
the
same
degree
as
they
did
a
year
ago,
while
more
than
a
quarter
say
that
they
are
now
even
better
aware
of
the
environmental
effect
on
what
they
buy.
This
may
help
to
( http: / / www.21cnjy.com )
influence
how
shops
store
goods
on
their
shelves.
And
the
companies
should
still
make
efforts
to
become
more
environmentally
friendly.
Two
out
of
three
people
think
it
is
important
to
buy
from
environmentally
responsible
companies,
with
about
one
in
seven
saying
that
they
had
even
decided
to
take
their
custom
elsewhere
if
they
felt
a
company’s
environmental
reputation
was
not
good
enough.
Harry
Morrison,
c
( http: / / www.21cnjy.com )hief
executive
(主管)
of
the
Carbon
Trust,
sympathizes:　“I
understand
this
situation
where
survival
is
very
important
now.
But
from
environmental
considerations,
the
clock
is
ticking—we
don’t
have
much
time.
In
addition,
cutting
carbon
has
an
immediate
effect
as
costs
drop
and
a
medium-term
benefit
for
the
brand.”
Larger
compan
( http: / / www.21cnjy.com )ies
have
an
extra
motivation
to
look
at
reducing
their
carbon
footprint,
as
new
rules
next
year
will
require
businesses
to
buy
carbon
allowances
to
make
up
for
their
emissions
(排放).
Those
that
have
taken
early
action
will
have
a
head
start.
More
than
two
thirds
of
consumers
are
not
clear
about
which
companies
are
environmentally
responsible.
This
suggests
that
firms
that
are
able
to
relay
clearly
their
message
to
the
public
will
be
in
a
pole
position
to
attract
shoppers.
The
Carbon
Trus
( http: / / www.21cnjy.com )t
believes
that
it
can
help
by
informing
customers
about
the
good
work
companies
are
doing.
“When
companies
are
granted
(授予)
the
standard,
they
can
use
a
logo
(标识)
in
all
their
marketing
which
makes
it
clear
that
they
are
working
towards
cutting
emissions,”
Mr.
Morrison
said.

in
business,
he
or
she
has
the
chance
to
earn
plenty
of
money
and
even
become
wealthy.
The
profit
earned
by
a
self-employed
person
is
the
reward
for
his
or
her
effort,
ability,
and
creativity.
Thus,
a
second
advantage
of
being
self-employed
is
that
a
person’s
intelligence
and
abilities
have
a
direct
effect
on
his
or
her
earnings.
People
who
have
outstanding
abilities
or
intelligence
often
find
they
can
earn
far
more
through
self-employment
than
they
can
through
working
as
an
employee.
A
third
advantage
of
being
self-employed
is
that
a
person
can
control
their
working
hours.
While
not
all
self-employed
people
are
completely
free
to
choose
whatever
hours
they
want
to
work,
most
of
them
have
more
control
over
this
area
than
the
people
who
work
for
salaries
or
wages.
As
with
most
things
( http: / / www.21cnjy.com )in
life,
being
self-employed
is
not
without
problems
first,
being
one’s
own
boss
places
the
responsibility
for
success
directly
on
that
individual’s
shoulders.
Abilities
and
intelligence
will
be
put
to
the
test.
Everyone
has
some
weaknesses
and
is
less
capable
in
some
things
than
in
others.
These
weaknesses
will
affect
how
successful
a
self-employed
person
is.
Second,
though
the
self-employed
can
earn
considerable
profits
with
a
successful
business,
losses
can
force
them
out
of
business
and,
in
some
instances,
place
them
in
debt.
A
third
disadvantage
concerns
income
security.
Self-employed
people
have
no
guaranteed
income.
Their
earnings
can
vary
greatly
from
year
to
year,
depending
on
business
conditions.
Salaried
people,
on
the
other
hand,
can
generally
count
on
continued
earnings
from
year
to
year.
In
addition,
salaried
people
often
enjoy
fringe
benefits(额外补贴),
which
are
all
of
the
benefits
provided
for
employees
in
addition
to
wages
and
salaries.
One
of
these
benefits
may
be
insurance
paid
for
by
the
employer
that
continues
the
employee’s
salary
in
the
event
of
sickness
or
accident.
Many
self-employed
people
do
not
have
such
protection,
unless
they
put
money
aside
themselves.

IV、阅读理解
A篇
1、B　细节理解题。首先，由转折词
( http: / / www.21cnjy.com )But判断，本句的意思应和文章前面所说“美貌是永恒的”在意义上相反。后面又介绍说“蒙娜·丽莎”的健康状况随着岁月的流逝而恶化，画的木板变形，因此断定此处的意思是指随着岁月的流逝，名画《蒙娜·丽莎》受到了损坏。
2、A　细节理解题。文章第四
( http: / / www.21cnjy.com )段提到，人们“正视”时，往往看不到“蒙娜·丽莎”的微笑，原因是当时达·芬奇是在暗处画得画，因此只有人们“不正视”时，才能看到她的微笑。
3、C　推理判断题。文章前面提到“蒙娜·丽莎”的历史像她的微笑一样是个谜，因此最后一段的意思是她还有一些秘密未被人知。
4、D　推理判断题。根据第三段最后一句可知，
( http: / / www.21cnjy.com )专家对于达·芬奇所用的材料及材料现在的化学状态没有把握，也就是说担心盲目修补会更加损坏此画。A项讲此画状况极差，观点过激与本文不符；B项本文未提及；C项与第三段最后一句不符。
