Ⅳ.阅读理解
A
When
middle aged
Alex
gave
up
his
job
and
made
up
his
mind
to
become
a
self employed
writer，no
one
could
tell
surely
whether
he
would
succeed
or
not.
He
found
a
cold
storage
room
in
a
building，set
up
a
used
typewriter
and
settled
down
to
work.
After
a
year
or
so，however，Alex
began
to
doubt
himself.
He
found
it
was
difficult
to
earn
his
living
by
selling
what
he
wrote.
But
Alex
determined
to
put
his
dream
to
the
test—even
though
it
meant
living
with
uncertainty
and
fear
of
failure.
This
is
the
shadowland
(虚幻世界)
of
hope，and
anyone
with
a
dream
must
learn
to
live
there.
One
day
Alex
got
a
call，“We
need
an
assistant，and
we're
paying
$6，000
a
year.”
$6，000
was
real
money
in
1960.It
would
enable
Alex
to
get
a
nice
apartment，a
used
car
and
more.
Besides，he
could
write
in
his
spare
time.
As
the
dollars
were
dancing
in
Alex's
head，something
cleared
his
senses.
He
had
dreamed
of
being
a
full time
writer.
“Thanks，but
no，”
Alex
said
firmly
and
swiftly.
After
Alex
got
off
the
phone，he
pulled
out
everything
he
had:
two
cans
of
vegetables
and
18
cents.
Alex
put
the
cans
and
cents
into
a
paper
bag，saying
to
himself，“There's
everything
you've
made
of
yourself
so
far.
I'm
not
sure
I
ever
felt
so
low.”
Finally
his
work
was
published
in
1970.Instantly
he
had
the
kind
of
fame
and
success
that
few
writers
ever
experience.
The
shadows
had
turned
into
focus
of
attention.
Then
one
day，Alex
found
a
box
filled
with
things
he
had
owned
years
before.
Inside
was
a
paper
bag
with
two
cans
and
18
cents.
Suddenly
he
pictured
himself
working
in
that
cold
storage
room.
It
reminds
Alex，and
anyone
with
a
dream，of
the
courage
and
persistence
(坚毅)
it
takes
to
stay
the
course
(坚持到底)in
the
shadowland.
1．Why
did
Alex
give
up
his
job？
A．Because
he
didn't
like
the
working
conditions.
B．Because
he
couldn't
earn
enough
to
make
a
living.
C．Because
he
felt
he
had
no
potential
in
his
job.
D．Because
he
wanted
to
be
a
full time
writer.
2．What
did
Alex
express
when
he
answered
the
call？
A．He
refused
the
job
offer.
B．He
was
willing
to
give
them
a
hand.
C．He
expected
them
to
pay
him
more
money.
D．He
would
write
in
his
spare
time.
3．What
kind
of
person
is
Alex？
A．Determined.
B．Modest.
C．Shy.
D．Brave.
4．Which
of
the
following
can
be
the
best
title
of
the
passage？
A．Look
before
you
leap
B．Two
heads
are
better
than
one
C．Hold
on
to
your
dream，and
it
will
come
true
D．A
bird
in
hand
is
worth
two
in
the
bush
B
Drinking
Water：Bottled
or
From
the
Tap(水龙头)？
In
America，people
will
include
a
case
or
two
of
bottled
water
when
buying
the
week's
groceries.
When
they
are
going
to
a
soccer
game
or
activity，it's
common
for
them
to
grab
a
cold
bottle
of
water
out
of
the
fridge
with
them.
In
fact，Americans
buy
more
bottled
water
than
any
other
nation
in
the
world，about
29
billion
bottles
a
year.
But
all
these
plastic
bottles
use
a
lot
of
fossil
fuels
and
pollute
the
environment.
In
order
to
make
all
the
29
billion
bottles，producers
use
17
million
barrels
of
oil，which
is
enough
to
keep
a
million
cars
going
for
12
months.
So
why
don't
people
drink
water
straight
from
the
tap？
Some
people
have
a
strong
belief
that
bottled
water
is
better
than
water
out
of
the
tap，but
that's
not
necessarily
true.
In
the
US，the
local
governments
make
sure
water
from
the
tap
is
safe.
There
is
also
growing
concern
that
chemicals
in
the
bottles
themselves
may
go
into
the
water.
People
love
the
convenience
of
bottled
water.
But
maybe
if
they
realized
the
problems
it
causes，they
would
try
drinking
from
a
glass
at
home
or
carrying
water
in
a
reusable
steel
container
instead
of
plastic.
Some
argue
that
plastic
bottle
recycling
can
help.
Recycled
bottles
can
be
turned
into
items
like
carpeting
or
clothing.
Unfortunately，only
one
in
six
bottles
is
recycled.
The
rest
make
it
to
landfills(垃圾填埋场)
or
end
as
trash
in
other
places.
Plastic
bottles
take
hundreds
of
years
for
them
to
disintegrate.
Water
is
important
for
you，so
keep
drinking
it.
But
think
about
how
often
you
use
water
bottles，and
see
if
you
can
make
a
change.
And
yes，you
can
make
a
difference.
Remember
this:
Recycling
one
plastic
bottle
can
save
enough
energy
to
power
a
60 watt
light
bulb
for
six
hours.
5．How
many
cars
can
be
kept
going
for
a
year
by
the
oil
used
to
make
29
billion
bottles？
A．100.
B．1，000.
C．100，000.
D．1，000，000.
6．Why
do
Americans
prefer
bottled
water？
A．Bottled
water
is
better
than
water
from
the
tap.
B．Bottled
water
is
cheaper
than
water
from
the
tap.
C．Bottled
water
contains
beneficial
chemicals
in
it.
D．Bottled
water
is
more
convenient
than
water
from
the
tap.
7．What
does
the
underlined
word
“disintegrate”
in
the
fifth
paragraph
probably
mean？
A．Be
well
recycled.
B．Become
less
poisonous.
C．Break
into
small
pieces.
D．Go
down
below
a
surface.
8．The
author's
intention
of
writing
this
passage
is
to
recommend
Americans
to________.
A．drink
more
water
from
the
tap
B．send
plastic
bottles
to
landfills
C．use
water
bottles
to
power
light
bulbs
D．buy
bottles
filled
with
water
from
the
tap
