Glass
can
be
seen
in
almost
all
the
windows.
Although
glass
is
trans-parent(透明的),
it
has
lots
of
disadvantages:
it
is
heavy,
breaks
easily
and
can
lose
heat.
What’s
more,
glass
making
creates
a
great
deal
of
pollution.
In
recent
years,
scientists
have
been
trying
to
find
greener
materials
to
replace
glass.
Last
October,
scientists
from
America
said
they
had
designed
“transparent
wood”
that
could
replace
glass
in
windows.
They
used
wood
from
the
balsa
tree,
which
is
native
to
South
and
Central
America.
First,
they
put
the
wood
in
an
oxidizing
bath(氧化剂)
that
can
help
make
the
wood
take
off
color.
Then
they
penetrated(注入)
a
kind
of
new
material—creating
a
product
that
is
transparent.
Transparent
wood
made
from
balsa
wood
is
much
stronger
than
glass
and
isn’t
fragile(易碎的).
So
it
is
much
safer
than
glass.
Also,
it
is
lighter
than
traditional
glass,
which
greatly
reduces
its
transportation
burden(负担).
What’s
more,
windows
with
transparent
wood
can
not
only
be
transparent,
but
also
help
stop
losing
heat.
More
importantly,
the
cost
of
producing
transparent
wood
is
lower,
and
producing
transparent
wood
can
create
little
pollution.
The
balsa
tree
is
one
of
the
fastest
growing
trees
on
the
earth.
So
people
can
get
enough
balsa
wood
to
produce
transparent
wood.
Maybe
windows
with
transparent
wood
will
be
seen
everywhere
in
the
near
future.
(　　)26.How
many
disadvantages
of
glass
are
mentioned
in
the
passage?
A.Two.
　　B.Three.
　　　　C.Four.
(　　)27.What
does
the
third
paragraph
mainly
tell
us?
A.The
process
of
making
transparent
wood.
B.The
reason
for
designing
transparent
wood.
C.The
materials
to
produce
transparent
wood.
(　　)28.Why
is
transparent
wood
safer
than
glass?
A.Because
it
is
much
lighter.
B.Because
it
is
not
broken
easily.
C.Because
it’s
made
of
wood.
(　　)29.Which
of
the
following
is
the
writer’s
view?
A.People
will
use
transparent
wood
to
keep

B.Scientists
will
know
more
about
transparent
wood.
C.Windows
with
transparent
wood

be
widely
used.

the

Tea
is
an
important
part
of
Chinese
tradition.
Tea
has
a
very
close
link
with
Chinese
culture.
It
is
said
that
Chinese
tea
was
invented
31.　　　　
an
ancient
Chinese
ruler
called
Shen
Nong.
People
say
that
he
lived
5,000
years
ago.
One
summer
day,
while
he
was
visiting
a
faraway
part
of
his
country,
he
felt
very
32.　　　　.
The
servants
began
33.　　　　
make
water
hot
enough
for
him
to
drink.
Dried
leaves
from
a
near
plant
34.　　　
　
into
the
water.
The
king
drank
some,
and
found
it
could
make
him
feel
less
tired.
Also
as
a
scientist,
Shen
Nong
was
35.　　　　
in
the
new
drink.
And
tea
36.　　　　
created
in
2737
B.C.?
Drinking
tea
has
many
advantages.
It
makes
people
feel
less
tired,
clears
heat
inside
the
human
body
and
helps
people
lose
weight.
As
you
add
a
cup
of
tea
to
37.　　　　
daily
life,
please
check
the
following
helpful
advice.?
?Drink
it
hot.
Tea
oxidizes(氧化)
quickly,
so
it
is
suggested
that
you
drink
it
hot.
?Do
not
drink
too
much
strong
tea.
38.　　　　
will
probably
be
harmful
to
your
stomach
and
make
you
feel
sick
if
you
make
the
tea
too
strong.?
?The
best
time
to
drink
tea
is
between
meals.
It
may
not
make
you
have
a
strong
wish
to
eat
39.　　　　
your
stomach
is
empty,
or
cause

when
your

Ⅴ.21.B　考查动词短语辨析。句意:
“杨明,你最钦佩谁?”“钟南山。不仅我而且我的同学都尊敬他。”look
forward
to意为“期盼;盼望”;look
up
to意为“敬仰,钦佩,仰慕”;be
up
to意为“达到”。根据语境可知选B。
22.C　考查动词的语态。句意:
篮球运动始于1891年。然后在1936年的柏林,它成为奥运会的一个项目。主语basketball是动词play动作的承受者,句子使用被动语态,所以排除选项A。由时间状语“in
1891”可知使用一般过去时的被动语态。
23.C　考查动词短语辨析。句意:史蒂芬·霍金是一位杰出的科学家,他有着顽强的意志,他严重的疾病从未　　　　他过有意义而丰富多彩的生活。learn
from意为“向……学习”;protect…from意为“保护……免受伤害”;stop…from意为“阻止……做……”。结合句意可知应选C。?
24.A　考查连词短语辨析。句意:
“玛丽,昨晚谁参加了毕业派对?”“几乎每个人都去了。不仅有很多学生,而且王老师也出现在派对上了。”not
only…but
also…意为“不但……而且……”;neither…nor…意为“两者都不”;either…or…意为“或者……或者……,不是……就是……”。根据语境可知选A。
25.B　考查短语辨析。the
number
of意为“……的数量”,后接复数名词作主语时,中心词是number,谓语动词用单数;其他三个短语修饰可数名词复数作主语时,谓语动词用复数。
Ⅵ.【主旨大意】
你能想象木头比玻璃更适合做窗户的材料吗?美国科学家最新研发的“透明木材”不但透明度可以媲美玻璃,而且比玻璃锁热能力更强、更环保、更耐用、更安全也更轻。
26.C　细节理解题。由第一段中的“…it
is
heavy,
breaks
easily
and
can
lose
heat.
What’s
more,
glass
making
creates
a
great
deal
of
pollution.”可知,文章中提到了玻璃的四个缺点:重、易碎、易散热和生产过程中产生污染。
27.A　段落大意题。综合第三段可知,这段主要介绍了透明木材的加工过程。
28.B　细节理解题。由第四段中的“Transparent
wood
made
from
balsa
wood
is
much
stronger
than
glass
and
isn’t
fragile.
So
it
is
much
safer
than
glass.”
可知,透明木材比玻璃更安全是因为它不易碎。
29.C　推理判断题。根据文章最后一句“Maybe
windows
with
transparent
wood
will
be
seen
everywhere
in
the
near
future.”可推断出,作者认为透明木材或许将被广泛应用。
30.A　主旨大意题。由全文整体内容判断,这篇文章主要介绍了透明木材的生产过程及其与玻璃相比的优势。

Ⅴ.完形填空
　　Have
you
ever
made
something
that
no
one
else
had
made
before?
People
who
make
something
new
are
called
　25　.
?
Victor
Ochoa
was
one
of
those
people.
He
　26　
many
things
and
one
of
them
was
a
flying
machine.
In
1908,
he
was
thinking
　27　
birds
used
their
wings
and
went
into
the
sky.
He
hoped
to
make
a
machine
that
　28　
like
a
bird.
Soon
he
took
action
and
began
to
　29　
birds
carefully
to
learn
how
their
wings
worked.
?
Finally,
he
used
what
he
learned
to
build
a
plane.
The
body
of
the
plane
was
made
of
two
　30　
side
by
side.
The
plane
had
a
small
motor(发动机)
that
sat
between
the
two
bikes.
The
back
was
shaped
like
a
bird’s
tail.
The
wings
were
　31　
from
a
common
plane.
?
They
could
even
be
folded(折叠)
down
like
a
bird’s
wings.
Amazing!
Victor
wanted
to
help
people
with
his
ideas.
His
mind
was
like
a
motor
that
never
turned
　32　.
He
was
always
trying
to
make
life
better
and
easier.
He
did
not
let
any
　33　
stop
him
from
making
other
things.
?
However,
not
all
of
his
ideas
worked.
No
one
who
tries
something
new
is
　34　
every
time.
The
most
important
is
to
keep
trying
and
never
give
up.?

This
12-year-old
Girl
Built
a
Robot
to
Find
Plastics
in
the
Ocean
Anna
Du
was
walking
along
the
beach
when
she
noticed
plastics
there.
She
reached
down
to
pick
them
up,
and
quickly
realized
there
were
many
more
tiny
pieces
than
she
could
deal
with.
It
seemed
impossible
to
clean
them
all
up.
Du,
12
years
old
at
that
time,
tried
to
solve
the
problem
like
any
good
scientist—first,
by
doing
a
little
research.
That’s
how
she
learned
that
8
million
tons
of
plastics
ends
up
in
the
oceans
every
year.
Then
she
got
to
work
building
something
that
could
help
solve
the
problem:
a
remote-operated
vehicle(遥控潜水器),
or
ROV.
Her
ROV
can
move
through
water
and
find
plastics
on
the
ocean
floor.
The
actually
cool
part
of
Du’s
ROV
is
the
detection(探测)
system.
She
uses
a
camera
along
with
three
different
kinds
of
light
to
find
the
plastics.
She
also
uses
visible(可见的)
light
to
find
unnatural
colors
that
might
make
the
plastics
stand
out.
“She
has
a
very
good
engineering
sense
to
break
down
a
problem
like
this
and
then
go
after
it,”
says
engineer
Casey
Machado.
“It
sounds
simple,
but
it’s
a
level
of
thinking
that’s
really
amazing.”
Du
started
attending
public
events
and
workshops
at
a
university
when
she
was
five
years
old,
and
so
she
picked
up
the
engineering
skills
necessary
to
build
her
ROV.
She
says
actually
getting
her
ROV
to
move
through
water
well
was
not
easy.
She
failed
many
times,
but
she
never
gave
up
trying
and
testing.
When
asked
about
future
plans,
she
mentions
wanting
to
address
the
effects
of
climate(气候)
change.
“I
think
there
are
a
lot
of
problems
that
could
be
solved
with
new
inventions,”
says
Du.
Du
thanks
her
parents,
who
for
years
have
taken
her
to
student
outreach
activities,
for
supporting
her
interest
in
science,
technology,
engineering
and
math(STEM).
She
says
she
has
been
able
to
meet
students
and
scientists
there.
“I
know
I
want
to
be
an
engineer
because
I
like
building
things
to
help
solve
world
problems,”
says
Du.
“But
I’m
not
sure
what
kind
of
engineer
I
want
to
be
yet.”
35.What
did
Anna
Du
notice
while
walking
along
the
beach?
?
36.How
old
was
Du
when
she
did
a
little
research
to
solve
the
problem?
?
37.What
can
Du’s
ROV
do?
?
38.Why
does
Du
want
to
be
an
engineer
in
the
future?
?
39.What
made
Du
succeed
in
building
her
ROV?
?
?
