二、完形填空(共15小题；每小题1分，满分15分)
阅读下面的短文，从短文后各题所给的A、B、C、D四个选项中，选择最佳选项。
There
are
purple
clothes,
purple
handbags,
purple
bicycles,
purple
furniture,
even
purple
computers！So
purple
is
one
of
the
most
__16__
colours
today.
But
in
the
past,
purple
was
a
very
expensive
and
unusual
colour.
Let's
take
a
look
at
the
rich
__17__
of
the
colour
purple.
Some
scientists
believe
that
the
first
plants
to
appear
on
the
Earth
over
500
million
years
ago
__18__
looked
purple,
not
green.
Plants
today
are
green
because
__19__
use
green
chlorophyll(叶绿素)
to
produce
energy.
__20__
these
early
plants
probably
used
something
called
retinal,
which
is
a
dark
purple
colour.
During
the
time
of
the
Roman
Empire(37
BC—476
AD),
it
was
very
__21__
to
make
purple
dye(染料).
The
dye
came
from
sea
snails(海螺).
But
10，000
dead
sea
snails
__22__
you
just
one
gram(克)
of
purple
dye…as
well
as
a
very
bad
smell!
This
__23__
purple
dye
was
called
Tyrian
purple,
and
it
was
the
preferred
__24__
of
emperors.
In
16th?century
England,
purple
was
__25__
for
the
king's
family
members.
Queen
Elizabeth
I's
clothes
were
purple,
but
ordinary
people
were
not
allowed
to
__26__
the
colour.
In
1856,
William
Perkin,
an
18?year?old
__27__
student,
noticed
something
strange
while
doing
an
experiment(实验).
The
chemicals(化学药品)
he
used
to
clean
his
instruments
__28__
with
the
chemicals
he
used
in
his
experiment
and
produced
a
bright
purple
colour.
This
__29__
led
Perkin
to
start
a
company
using
this
chemical
mixture
to
make
purple
dye.
The
dye
was
much
__30__
than
sea?snail
dye.
Thanks
to
Perkin,
now
anyone
can
afford
to
wear
purple
clothes.

三、阅读理解(共15小题；每小题2分，满分30分)
阅读下列短文，从短文后各题所给的
A、B、C、D
四个选项中，选择最佳选项。
A
If
you
go
shopping
in
any
toy
store,
you
can
see
clearly
the
different
games
and
toys
for
boys
and
girls:
there
are
a
lot
of
pink
toys
on
one
side
of
the
store
for
girls;
and
dark?coloured
cars,
guns,
and
soldiers
for
boys.
Some
big
stores
with
toys
may
even
have
a
pink
floor
for
girls
and
a
blue
floor
for
boys.
In
fact,
it
is
difficult
to
buy
a
toy
for
a
girl
that
is
not
pink.
Some
people
think
that
too
much
pink
is
bad
for
girls.
Sue
Palmer,
writer
of
Toxic
Childhood,
is
very
worried
that
most
girls
over
the
age
of
three
are
crazy
about
the
colour.
According
to
some
scientists,
this
happens
for
two
reasons.
Firstly,
most
companies
offer
too
many
products
in
pink.
Also,
many
parents
think
their
little
daughter
looks
cute
in
pink.
Sue
Palmer
says
that
girls
at
this
age
cannot
make
proper
decisions
by
themselves,
but
the
pink
can
affect(影响)
the
choices
and
the
decisions
they
will
make
in
the
future.
Some
parents
are
worried
too—for
example,
Vanessa
Holburn,
thirty?two,
who
has
two
girls
under
the
age
of
four.
Their
bedrooms
are
a
sea
of
pink
and
Vanessa
is
not
happy.“Pink
says
that
you
are
soft
and
gentle.
Blue
says
that
you
are
strong
and
powerful.
I
want
my
daughters
to
be
strong
and
powerful.
I'm
worried
that
pink
will
not
help
them
with
that，”
she
says.
But
not
everyone
thinks
there's
something
wrong
with
pink.
Grayson
Turner
is
a
father
of
three
girls
and
he
isn't
worried
at
all.“People
forget
that
things
change
all
the
time，”
he
says.“My
girls
used
to
love
pink
when
they
were
little,
but
as
they
get
older,
they
change.”
Turner
explains
that
his
twelve?year?old
daughter
never
wears
pink
clothes
anymore.
“This
love
of
pink
is
just
a
fashion
and
all
fashions
change，”
he
adds.
“It's
only
since
the
1940s
that
people
have
started
dressing
girls
in
pink—before
that
it
was
a
colour
for
boys.”
(　　)31.The
underlined
word
“that”
in
Paragraph
3
means
________．
A．being
soft
and
gentle
B．being
strong
and
powerful
C．being
gentle
but
powerful
D．being
cute
and
beautiful
(　　)32.According
to
Grayson
Turner,
________．
A．parents
needn't
worry
about
pink
toys
B．all
little
kids
love
the
colour
pink
C．pink
has
always
been
a
colour
for
girls
D．his
girls
now
prefer
the
colour
blue
(　　)33.The
purpose
of
this
passage
is
to
________．
A．explain
why
girls
are
crazy
about
the
colour
pink
B．make
parents
less
worried
about
the
colour
pink
C．encourage
girls
to
give
up
playing
with
pink
toys
D．show
people's
different
opinions
about
the
colour
pink
B
The
idea
that
red
means
stop
and
green
means
go
has
influenced
our
lives
in
more
ways
than
just
traffic
signals(信号).
We
have
been
taught
from
a
young
age
that
the
colour
red
means
danger
and
green
means
it's
okay
to
move
forward.
But
why
were
those
colours
chosen
for
traffic
lights
in
the
first
place?
For
something
we
have
to
look
at
every
day,
why
couldn't
they
have
been
prettier
colours?
Well,
it's
important
to
know
that
before
traffic
lights
for
cars,
there
were
traffic
signals
for
trains.
At
first,
railway
companies
used
red
to
mean
stop,
white
to
mean
go,
and
green
to
mean
warn.
As
you
could
imagine,
trains
ran
into
a
few
problems
with
white
meaning
go.
For
example,
one
train
mistook
a
bright
star
for
a
white
light
and
something
unexpected
happened.
Because
of
that,
railway
companies
finally
moved
green
meaning
go
and
used
yellow
to
mean
warn.
And
it's
been
that
way
ever
since.
Red
has
always
been
a
colour
that
meant
danger,
long
before
cars
were
even
around.
This
most
likely
started
because
it's
the
colour
with
the
longest
wavelength(波长)
so
it
can
be
seen
somewhere
farther
than
other
colours.
But,
believe
it
or
not,
yellow
was
once
used
to
mean
stop.
Back
in
the
1900s,
some
stop
signs
were
yellow
because
it
was
too
hard
to
see
a
red
sign
in
a
poorly
lit
area.
Finally,
highly
reflective
materials(高反射材料)
were
developed
and
red
stop
signs
were
born.
Since
yellow
can
be
seen
well
at
all
times
of
the
day,
school
zones,
some
traffic
signs
and
school
buses
continue
to
be
printed
yellow.
So
next
time
you
are
impatiently
waiting
at
a
traffic
light,
don't
get
so
mad
at
them.
They've
certainly
come
a
long
way.
(　　)34.What
were
traffic
signals
for
before
traffic
lights
for
cars?
A．Trains.
B．Boats.
C．Planes.
D．Bicycles.
(　　)35.Why
does
red
mean
danger?
A．Because
it's
the
brightest
colour.
B．Because
it
can
be
seen
far
away.
C．Because
railway
companies
say
so.
D．Because
it
has
the
shortest
wavelength.
(　　)36.Why
are
school
buses
painted
yellow?
A．Because
yellow
is
a
prettier
colour.
B．Because
yellow
once
meant
danger.
C．Because
yellow
can
be
seen
well
in
daytime.
D．Because
yellow
means
it's
OK
to
go
forward.
(　　)37.What
does
the
text
mainly
tell
us?
A．How
important
traffic
lights
are.
B．Which
colour
has
the
longest
wavelength.
C．What
red,
yellow
and
green
can
be
used
for.
D．Why
traffic
lights
are
red,
yellow
and
green.
C
Many
everyday
American
expressions
are
based
on
colours.
Red
is
a
hot
colour.
Americans
often
use
it
to
express
heat.
They
may
say
they
are
red
hot
about
something
unfair.
When
they
are
red
hot
they
are
very
angry
about
something.
The
small
hot
tasting
peppers
found
in
many
Mexican
foods
are
called
red
hots
for
their
colour
and
their
fiery
taste.
Pink
is
a
lighter
kind
of
colour.
People
sometimes
say
they
are
in
the
pink
when
they
are
in
good
health.
It
probably
comes
from
the
fact
that
many
babies
are
born
with
nice
pink
skin
that
shows
that
they
are
in
good
health.
Blue
is
a
cool
colour.
The
traditional
blues
music
in
the
United
States
is
the
opposite
of
red
hot
music.
Blues
is
slow,
sad
and
soulful.
Someone
who
is
blue
is
very
sad.
The
colour
green
is
natural
for
trees
and
grass.
But
it
is
an
unnatural
colour
for
humans.
A
person
who
has
a
sick
stomach
may
say
he
feels
a
little
green.
A
passenger
on
a
boat
who
is
feeling
very
sick
from
high
waves
may
look
very
green.
If
a
person
is
green
at
his
job,
he
may
be
a
newcomer
and
inexperienced.
Sometimes
a
person
may
be
upset
because
he
does
not
have
something
as
nice
as
a
friend
has,
like
a
new
sports
car.
That
person
may
say
he
is
green
with
envy.
Some
people
are
green
with
envy
because
their
friend
has
more
dollars.
The
colour
black
is
often
used
in
expressions.
People
describe
a
day
on
which
everything
goes
wrong
as
a
black
day.
The
date
of
a
major
tragedy
is
remembered
as
a
black
day.
(　　)38.If
a
person
feels
blue,
he
is
________．
A．annoyed
B．depressed
C．stressed
D．encouraged
(　　)39.If
someone
says
“you
are
still
green”，
he
probably
means
that
________．
A．you
are
very
young
B．you
are
in
a
bad
mood
C．you
are
inexperienced
D．you
are
in
good
health
(　　)40.Which
of
the
following
statements
is
CORRECT
according
to
the
passage?
A．After
a
good
night's
rest,
the
soldiers
were
all
in
the
pink.
B．They
had
a
fierce
quarrel
so
they
all
felt
black
about
it.
C．David
got
hurt
by
a
bike
so
his
face
looked
pink.
D．When
we
meet
something
unfair,
we
feel
very
green.
(　　)41.What's
the
main
idea
of
the
passage?
A．Different
colours
have
different
meanings.
B．What
different
colours
stand
for.
C．The
story
about
different
colours.
D．Colours
used
in
American
expressions.
D
Traffic
lights
are
red,
yellow
and
green.
They
are
very
important
signals.
Traffic
lights
are
usually
placed
at
busy
street
corners
to
help
control
traffic.
Sometimes,
they
are
on
streets
near
schools
and
shops,
too.
Most
young
children
are
taught
what
each
of
the
coloured
lights
means,
so
everybody
can
stay
safe.
The
first
traffic
signals
were
used
for
trains.
The
signals
were
put
alongside
railway
tracks(轨道).
The
colour
red
was
used
to
mean
“stop”
because
it
warned
people
of
danger.
A
red
light
was
also
the
easiest
colour
to
see
from
a
distance.
Train
drivers
could
see
the
red
“stop”
light
ahead
and
had
enough
time
to
slow
down
and
stop
their
trains.
A
green
light
was
used
to
mean
“take
care”
and
a
white
light
meant
“go”.
However,
there
were
many
dangerous
accidents
on
the
train
tracks.
Some
train
drivers
thought
a
star
shining
in
the
night
sky
was
a
white
light
that
meant
“go”.
So
the
signals
were
swapped.
The
“go”
light
was
changed
to
green
and
the
“take
care”
light
was
changed
to
white.
During
these
times,
people
travelled
by
train
or
in
carts
pulled
by
horses.
Years
later,
when
cars
were
built,
people
began
to
drive
them
because
they
could
travel
much
faster
than
horses.
However,
the
road
rules
for
drivers
were
not
very
clear
and
many
people
were
hurt
crossing
the
roads.
Yellow
warning
signs
had
to
be
placed
beside
the
roads
to
remind
drivers
to
take
care
and
allow
people
to
cross
safely.
Today,
towns
and
cities
all
over
the
world
have
traffic
lights.
Red
and
green
lights
match
the
signals
used
on
the
railways.
Yellow
lights
are
easy
to
see,
so
they
are
used
to
warn
drivers
that
they
should
slow
down
and
prepare
to
stop.
(　　)42.Why
was
the
colour
red
used
to
mean
“stop”？
A．It
reminded
people
of
traffic
rules.
B．It
helped
trains
run
smoothly.
C．It
gave
people
a
warning
of
danger.
D．It
was
the
first
colour
people
thought
of.
(　　)43.What
does
the
underlined
word
“swapped”
in
Paragraph
3
mean?
A．Designed.
B．Exchanged.
C．Suggested.
D．Compared.
(　　)44.In
which
order
did
the
“take

六、One
possible
version：
Colours
and
Moods
Do
you
know
anything
about
the
relationship
between
colours
and
moods?
Green
is
an
energetic
colour.
It
can
give
you
energy,
as
it
is
the
colour
of
nature
and
represents
new
life.
So
when
you
are
tired
or
weak,
you
can
wear
green
clothes.
Red
is
a
strong
colour.
It
can
make
you
look
more
powerful.
It
also
represents
good
luck
in
China
and
many
women
preferred
to
wear
red
on
their
wedding
day
in
the
past.
My
favourite
colour
is
white
because
it
is
the
colour
of
purity
and
it
can
help
me
calm
down
when
I
feel
nervous.
All
the
colours
make
our
world
colourful
and
wonderful.
