四、完形填空(每小题1分，共20分)
Are
forests
always
created
by
nature?
A
man
from
India
proves
that
this
is
not
necessarily
31
.
Abdul
Kareem,
who
used
to
be
an
airline
ticketing
agent,
has
a
great
love
for
the
32
.
33
he
never
went
to
college,
he
can
talk
about
plants
and
trees
like
an
expert.
In
1977,
he
bought
a
piece
of
34
wasteland
with
the
dream
of
growing
trees
on
it.
In
the
beginning,
people
thought
he
was
35
to
waste
his
time
and
money
on
the
land.
But
he
simply
36
them
and
kept
37
the
soil
and
planting
trees
there.
The
land
was
so
dry
that
it
had
to
be
38
several
times
a
day.
Kareem
had
to
39
the
water
from
a
source
that
was
a
kilometer
away.
In
the
first
two
years,
none
of
the
trees
he
planted
40
.
However,
in
the
third
year,
several
young
trees
started
growing.
Greatly
41
by
the
result,
Kareem
planted
more
trees
and
his
man?made
forest
began
to
42
.
Kareem
let
his
forest
grow
43
，
without
using
any
chemicals
to
help
it
grow
or
44
insects.
He
45
the
ability
of
nature
to
renew
46
.
That's
47
he
did
not
allow
fallen
leaves
or
twigs
from
the
forest
to
be
removed.
After
years
of
hard
work,
Kareem
has
not
only
realized
his
dream
48
transformed
a
piece
of
deserted
property
into
a
beautiful
forest
as
well.
Today,
his
forest
is
49
to
1,500
medicinal
plants,
2,000
varieties
of
trees,
rare
birds,
animals,
and
insects.
Now,
scientists
from
all
over
the

五、阅读选择(每小题2.5分，共10分)
Starting
in
the
late
1980s,
the
plastics
industry
spent
tens
of
millions
of
dollars
encouraging
recycling
through
ads
and
recycling
projects,
telling
people
plastics
could
be
recycled,
but
their
own
internal
records
showed
that
industry
officials
long
knew
that
plastic
recycling
on
a
large
scale
comes
with
high
costs
but
poor
results.
A
report
sent
to
top
industry
directors
in
1973
said
that
plastic
recycling
was
not
as
easy
as
people
thought
and
sorting
plastic
was
impractical.
Another
document
a
year
later
showed
that
there
was
serious
doubt
that
plastic
recycling
can
get
profits
on
an
economic
basis.
Despite
this,
three
former
top
officials
said
the
industry
supports
recycling
as
a
way
to
beat
back
a
growing
trend
of
stopping
using
plastics
in
the
1980s.
“The
plastics
industry
is
under
fire,
but
we
want
to
continue
to
make
plastic
products,”
Thomas,
an
official
from
a
company
making
plastics
says.“
If
the
public
think
the
recycling
is
working,
then
they’re
not
going
to
be
so
worried
about
the
environment.”
“The
public
gradually
doubt
the
idea
that
the
plastics
industry
could
do
a
satisfying
job
in
dealing
with
plastics
and
protecting
the
environment.
But
now
we
have
already
funded
new
technologies
to
change
this
situation.
We
don’t
want
to
see
the
pollution
of
the
environment
either
and
are
willing
to
solve
the
problem,”
says
Jim
Becker,
vice
president
of
Chevron
Phillips
Plastics
Company.
However,
the
more
plastics
are
recycled,
the
less
money
the
industry
will
make.
And
the
industry
now
produces
many
more
different
kinds
of
plastics
that
are
more
costly
to
sort
and
in
many
cases
can’t
be
recycled
at
all.
Efforts
to
reduce
the
use
of
plastics
are
increasing
worldwide,
but
any
plan
to
slow
the
growth
of
plastics
will
cause
the
whole
industry
to
lose
billions
of
dollars
in
the
future.
51．What
problem
is
mentioned
in
the
first
paragraph?
A．Too
expensive
plastics
recycling.
B．Failure
in
recycling
plastics
in
right
ways.
C．Lack
of
advanced
technologies
in
plastic
recycling.
D．Environmental
problems
from
increasing
recycling
needs.
52．According
to
Paragraph
3,
companies
making
plastics_______.
A．don’t
make
new
plastics
products
B．try
to
teach
people
to
sort
plastic
products
C．encourage
people
to
recycle
plastics
for
more
sales
D．think
environmental
problems
are
hard
to
deal
with
53．What
can
be
learned
from
Becker’s
words
in
Paragraph
4?
A．He
devotes
himself
to
selling
more
high-tech
products.
B．He
wants
to
change
the
public’s
understanding
of
plastics.
C．The
plastics
industry
is
praised
by
the
public
for
its
efforts.
D．The
plastics
industry
starts
taking
on
more
social
responsibilities.
54．What’s
the
main
idea
of
the
last
paragraph?
A．Reducing
plastics
production
has
become
a
new
trend.
B．Changes
in
prices
of
plastics
increase
the
difficulty
of
recycling.
C．Plastics
recycling
puts
the
plastics
industry
in
a
difficult
situation.
D．The
plastics
industry
spends
more
improving
the
plastics
quality.
【答案】
这是一篇说明文。文章主要说明了如今塑料回收成本高，效果不佳的问题，指出制造塑料的公司鼓励人们回收塑料是为了获得更多的销售，但是塑料工业已经开始愿意承担更多的社会责任。全世界都在努力减少塑料的使用，但任何减缓塑料增长的计划都将导致整个行业在未来损失数十亿美元。
51．A
细节理解题。根据第一段“Starting
in
the
late
1980s,
the
plastics

spent
tens
of
millions

encouraging
recycling
through

52．C
细节理解题。根据第三段中““The
plastics
industry
is
under
fire,
but
we
want
to
continue
to
make
plastic
products,”
Thomas,
an
official
from
a

then
they’re

to
be
so
worried
about
the
environment.”(一家塑料制造公司的官员托马斯表示：“塑料行业正受到攻击，但我们希望继续生产塑料产品，如果公众认为回收是有效的，那么他们就不会那么担心环境了。”)”可知，制造塑料的公司鼓励人们回收塑料是为了获得更多的销售。故选C。
53．D
推理判断题。根据倒数第二段““The
public
gradually
doubt
the
idea
that
the
plastics

do
a

Company.(
雪佛龙菲利普斯塑料公司副总裁Jim
Becker说：“人们逐渐怀疑塑料行业在处理塑料和保护环境方面能做得令人满意。但是现在我们已经资助了新技术来改变这种情况。我们也不想看到环境污染，我们愿意解决这个问题”)”可推知，从Becker的话中我们可以了解到塑料工业开始承担更多的社会责任。故选D。
54．C
主旨大意题。根据最后一段“However,
the
more
plastics
are
recycled,
the
less
money
the
industry
will
make.
And
the
industry
now
produces
many
more
different
kinds
of
plastics
that
are
more
costly
to
sort
and
in
many
cases
can’t

at
all.
Efforts
to
reduce
the

of
plastics
are
increasing
worldwide,

any
plan
to
slow
the
growth
of
plastics
will
cause
the
whole
industry
to
lose
billions
of
dollars
in
the
future.(然而，回收的塑料越多，这个行业赚的钱就越少。该行业现在生产了更多不同种类的塑料，分类成本更高，在很多情况下根本无法回收。全世界都在努力减少塑料的使用，但任何减缓塑料增长的计划都将导致整个行业在未来损失数十亿美元)”可知，最后一段的主要思想是塑料回收使塑料工业陷入困境。故选C。

这是一篇记叙文，文章介绍了一个海洋爱好者Fabien
Cousteau为追随家人的脚步，试图保护地球上濒临灭绝的海洋生物的事迹。
55．考查名词。句意：他的祖父和父亲是海洋探险家和纪录片制片人。根据下文“and
documentary
filmmakers”可知，设空处为名词复数，故填explorers。
56．考查时态和主谓一致。句意：如今，Fabien追随家人的脚步，试图保护地球上濒临灭绝的海洋生物，并在环境问题和市场经济之间取得平衡。根据“Today”可知，句子描述目前的情况，用一般现在时，主语为Fabien，谓语动词用第三人称单数形式。故填follows。
57．考查冠词。句意：如今，Fabien追随家人的脚步，试图保护地球上濒临灭绝的海洋生物，并在环境问题和市场经济之间取得平衡。reach
a
balance达到平衡，是固定短语，故填a。
58．考查时态。句意：2001年，他根据1916年发生在新泽西海岸线上的鲨鱼袭击事件制作了一个电视特别节目。分析可知，设空处为定语从句的谓语动词，根据“in
1916”可知，此处为一般过去时，故填occurred。
59．考查介词。句意：然后在2003年，在一大批船员的帮助下，Fabien造了一艘鲨鱼潜艇，使他能够把自己置身于鲨鱼世界。with
the
help
of是固定短语，意为“在……的帮助下”，故填with。
60．考查反身代词。句意：然后在2003年，在一大批船员的帮助下，Fabien造了一艘鲨鱼潜艇，使他能够把自己置身于鲨鱼世界。根据“enabled
him
to
put”及句意可知，此处指“使他能够把他自己置于鲨鱼世界”，应用反身代词，故填himself。
61．考查定语从句。句意：在接下来的四年里，Fabien参加了一个名为“海洋探险”的系列活动，该活动让我们得以一窥一些最神奇的海洋物种。本句为非限制性定语从句，修饰先行词a
series，指物，且关系词在从句中作主语，故用关系代词which，故填which。
62．考查非谓语动词。句意：在2010年，Fabien和他的团队在水下待了31天，探索影响海洋的气候变化和污染。待了31天的目的就是去探索，故用动词不定式作目的状语，故填to
discover。
63．考查副词。句意：Fabien目前正在拍摄一部关于《使命冒险31》的纪录片，并正在建设一个海洋学习中心，为孩子们提供学习海洋的机会。修饰动词working应用副词，故填currently。
64．考查时态。句意：Fabien目前正在拍摄一部关于《使命冒险31》的纪录片，并正在建设一个海洋学习中心，为孩子们提供学习海洋的机会。as
well
as表示“也；不但……而且”，连接两个并列谓语，根据上文working可知，此处应和working保持一致，用现在分词形式，故填building。

With
advances
in
transportation
and
information
technology,
even
the
most
remote
places
on
Earth
are
within
reach
of
the
traveler.
In
fact,
tourism
is
now
the
world’s
largest
industry,
with
nature
tourism
growing
the
fastest.
65．
In
response
to
this
increasing
appreciation
of
nature
experiences,
a
new
form
of

Union
for
Conservation
of
Nature
(IUCN):
Environmentally
responsible
travel
to
natural
areas,
in
order
to
enjoy
and
appreciate
nature
that
promotes
conservation,
has
a
low
visitor
influence
and
provides
for
beneficially
active
socio-economic
involvement
of
local
people.
Increased
tourism
to
sensitive
natural
areas
without
appropriate
planning
and
management
can
threaten
(威胁)
the
whole
of
ecosystems
and
local
cultures.67．
Likewise,
local
communities
and
can
be
harmed
in
numerous
ways
by
crowded
foreign
visitors
and
wealth.
68．
Ecotourism
can
provide
much-needed
revenues
(收益)
for
the
protecting
of
national
parks
and
other
natural
areas,
which
might
not
be
available
from
other
sources.
Additionally,
ecotourism
can
provide
a
practical
economic
development
alternative
for
local
communities
with
few
other
income-generating
options.
Besides,
ecotourism
can
increase
the
level
of
education
and
activism
(积极)
among
travelers.69．
A．What
is
ecotourism?
B．The
growth
of
the
ecotourism
income
is
also
beneficial
to
the
local
people.
C．And
it
makes
them
more
enthusiastic
and
effective
spokesmen
for
conservation.
D．But
most
of
the
tourism
in
natural
areas
nowadays
is
not
ecotourism
at
all.
E.
However,
this

growth
does
good
to
both
conservation
and
local
communities.
F.
People
want
to
experience
nature,
but
should
try
not

【答案】
试题分析：这是一篇说明文，主要介绍了一种新型的旅游形式——生态旅游。
65．F
考查上下文理解和推理判断。由下文“In
response
to
this
increasing
appreciation
of
nature
experiences,
a
new
form
of
travel
has
arisen
called
ecotourism.”可知，随着日益增多对自然体验的欣赏，一种新的旅游形式，生态旅游出现了。因此推断F项“人们想要体验自然，但是应当努力不要影响自然环境”符合语境，“生态旅游”不会影响自然环境。故选F。
66．A
考查上下文理解推理判断。由空格下文可知，自然保护区采用国际自然保护联盟(IUCN)所解释的概念：对环境负责的自然区域旅行，享受和欣赏自然推进对自然的保护，具有较低的游客影响，积极参与当地的社会经济活动。
这是介绍生态旅游的概念，故选A。
67．F
考查上下文理解和推理判断。由空格上文“Increased
tourism
to
sensitive
natural
areas
without
appropriate
planning
and
management
can
threaten
(威胁)
the
whole
of
ecosystems
and
local
cultures.”可知，没有适当的规划和管理，增加对敏感自然地区的旅游可能会威胁整个生态系统和当地文化。因此推断G项“前往生态敏感地区的游客增加，可能会对环境造成很大损害”符合语境。故选F。
68．E
考查上下文理解和推理判断。由下文“Ecotourism
can
provide
much-needed
reveriues
(收益)
for
the
protecting
of
national
parks
and
other
natural
areas,
which
might
not
be
available
from
other
sources.”可知，生态旅游可以为保护国家公园和其他自然区域提供急需的收益，这些可能无法从其他资源获得。因此推断E项“然而，同样的增长对于环保和当地社区都有好处”
符合语境，故选E。
69．C
考查上下文理解和推理判断。由上文“ecotourism
can
increase
the
level
of
education
and
activism
(积极)
among
travelers”可知，生态旅游可以提高旅行者的教育和积极性水平。因此推断C项“生态旅游让他们成为热情的，有效的环境发言人”符合语境。故选C。2021-2022学年北师大版（2019）高中英语：选择性必修一
