二、完型填空
Do
you
often
use
plastic
straws（吸管）?
You
probably
use
them
to
16
lots
of
things
such
as
cola
or
milk
tea.
Plastic
straws
are
small
17
they
are
a
big
problem.
They
are
made
in
10
minutes,
used
in
20
18
and
normally
remain
on
the
earth
for
over
100
years
since
they
cannot
be
19
easily.
In
fact,
around
500
million
plastic
straws
are
used
every
day
in
our
country.
That
is
enough
to
circle
20
two-and-a-half
times
around
our
planet!
If
we
didn’t
act
now,
there
would
be
21
plastic
in
the
ocean
than
fish
by
2050.
Luckily,
more
and
more
people
around
the
world
have
realized
this
problem.
They
begin
to
think
about
22
plastic
straws
are
necessary
or
not
when
drinking
drinks.
So
what
can
we
do
right
now
to
reduce
plastic
pollution?
The
simplest
way
is
to
say
“no”
to
single-use
plastic,
like
straws.
For
example,
next
time
if
you
go
to
a
restaurant,
make
sure
you
order
your
drink
without
a
straw.
What
if
people
need
to
use
a
straw?
There
are
reusable
straws
instead.
These
straws
can
be
used,
23
,
and
reused
over
and
over
again.
Coffee
house
Starbucks
has
started
to
24
paper
straws
instead
of
plastic
straws
in
almost
1,000
stores
in
Shanghai
and
Shenzhen.
Starbucks
is
not
alone.
McDonald’s
has
25
taken
action
to
reduce
the
use
of
plastic
straws.
It
is
hoped
that
more
businesses
and
customers
will
work
together
to
protect
our
environment.
16．A．drink
B．eat
C．tie
D．make
17．A．and
B．but
C．or
D．so
18．A．seconds
B．minutes
C．hours
D．days
19．A．cut
down
B．written
down
C．broken
down
D．put
down
20．A．closely
B．nearly
C．specially
D．particularly
21．A．more
B．fewer
C．less
D．better
22．A．whether
B．if
C．why
D．what
23．A．repaired
B．burned
C．picked
D．cleaned
24．A．offer
B．afford
C．affect

【分析】
本文是一篇说明文。文章主要介绍了塑料吸管污染环境的严重程度以及解决这种塑料污染的一些措施。
16．
句意：你可能用它们来喝很多东西，比如可乐或奶茶。
drink喝；eat吃；tie系；make制作。结合上下文可知，此句的“them”指代的是上句提及的“
plastic
straws（吸管）”；根据常识可知，吸管是用来喝饮料的，所以A选项符合句意。故选A。
17．
句意：塑料吸管虽小，但却是个大问题。
and和；but但是；or或者；so所以。本句的上半句和下半句，即“塑料吸管小”和“塑料吸管是大问题”，句意上有转折，所以横线处应填表示转折关系的连词but。故选B。
18．
句意：它们在10分钟内制成，在20分钟内使用，由于不易分解，通常会在地球上存在100多年。
seconds秒；minutes分钟；hours小时；days天。根据日常生活经验可知，饮用完一杯饮料，也就是使用吸管的时间为“20分钟”较为适合。故选B。
19．
句意：它们在10分钟内制成，在20分钟内使用，由于不易分解，通常会在地球上存在100多年。
cut
down砍倒；written
down记下，写下；broken
down（使）分解；put
down放下。根据常识以及备选选项可知，塑料是不易分解的东西，所以才会在地球上存在这么长时间。故选C。
20．
句意：这足够绕地球近两圈半了！
closely紧密地；nearly几乎；specially特别地；particularly尤其。结合上下文语境可知，本句的“That”指代的是上文的“500
million
plastic
straws”这个总数，而5亿条吸管绕地球的圈数并不可能准确测量，所以此处应选用可以表示概数的副词，B选项符合语境，表示“接近两圈半”的意思。故选B。
21．
句意：如果我们现在不采取行动，到2050年，海洋中的塑料将超过鱼类。
more更多的；fewer更少的；less更少的；better更好的。根据上文“
That
is
enough
to
circle
…
two-and-a-half
times
around
our
planet!”可知，此段都在表示现今塑料吸管的数量太过庞大，由此可知，此处也应是数量“多于”鱼类。故选A。
22．
句意：他们开始思考喝饮料时是否需要塑料吸管。
whether是否；if是否；why为什么；what什么。根据“or
not”可知，此处考查“whether…or
not”的搭配，表示“是否”的意思。故选A。
23．
句意：这些吸管可以被反复使用、清洗，再重复使用。
repaired维修；burned燃烧；picked挑选；cleaned清洗。根据横线前的“use”和横线后的“reuse”可推测，吸管在使用一次过后可能会变脏，所以在再次使用之前应是需要清洗的。故选D。
24．
句意：咖啡馆星巴克已经开始在上海和深圳的近1000家门店提供纸吸管而不是塑料吸管。
offer提供；afford负担；affect影响；produce生产。根据常识可知，星巴克咖啡的主营产品是饮料，所以它应是会随饮料向顾客提供吸管以便顾客饮用。故选A。
25．
句意：麦当劳也采取行动减少塑料吸管的使用。
still仍然；also也；ever曾经；just仅仅。根据上文“Coffee
house
Starbucks
has
started
to…paper
straws
instead
of
plastic
straws”可知，星巴克为了减少使用塑料吸管，已经开始使用纸吸管了；而此句也提及了麦当劳采取行动减少使用塑料吸管，这是和星巴克同样的目的，所以“also”符合此语境。故选B。
26．B
27．A
28．C
29．C
30．A
【分析】
本文是关于学生对环境污染的了解以及如何分类垃圾的一个调查问卷结果。

how
many
students
knew
about
each
kind
of
the
pollution
and
we
wanted
to
learn
how
often
they

rubbish”可知，这个调查报告主要是关于环境保护的，故选B。
27．
细节理解题。根据“Do
you
know
about
these
problems”及“How
often
do
you
sort
rubbish”可知，问卷有两部分，故选A。
28．
细节理解题。根据图表显示，关于噪声污染学生们了解的最少，故选C。
29．
细节理解题。根据图表显示，25%的学生已经开始分类垃圾，也就是一些学生已经开始这么做了，故选C。
30．
细节理解题。根据图表显示，90%的学生已经注意到空气污染问题，故选A。
31．B
32．E
33．A
34．F
35．D
【分析】
31．
句意：经常熬夜对我们的健康有害。根据“does…to
our
health”及备选词，可知，此空用do
harm
to
表示“对……有害”，故选B。
32．
句意：陈静想要有自己的个人电脑。此空缺少形容词修饰名词computer，备选词personal“个人的”符合，故选E。
33．
句意：尽管他只有三岁，但他可以找到回家的路。“He
could
find
the
way
home”与“he
was
only
three
years
old”是转折关系，备选词though“尽管”引导让步状语从句，故选A。
34．
句意：去哪里度假取决于你有多少时间和多少钱。根据“Where
to
go
on
a
vacation…how
much
time
and
money
you
have”及备选词，可知，去哪度假是由时间和金钱决定的，此空用depend
on“取决于”符合语境，故选F。
35．
句意：在伟大科学家的努力下，中国成功研制了新型冠状病毒疫苗。根据“China
has…in
developing
COVID-19
vaccines”及备选词，可知，此处用succeed
in
doing
sth表示“成功做某事”，故选D。
36．avoid
making
learn
from
【解析】
avoid“避免”，avoid
doing
sth“避免做某事：make
mistakes“犯错误”；learn
from“从……中学习”，情态动词can后接动词原形，故填avoid；making；learn；from。
37．avoid
eating
【解析】
根据中英文对比可知，英文句子中缺少“避免吃”的表达，“避免”翻译为“avoid”，“吃”翻译为
“eat”；根据短语“tell
sb.
to
do
sth.（告诉某人做某事）”可知，此处应用动词不定式作宾补，to已在句中出现，所以第一空应填动词原形avoid；又根据短语“avoid
doing
sth.（避免做某事）
”可知，avoid后应接动名词作宾语，所以第二空应填eat的动名词形式eating。故填avoid；eating。
38．failed
to
avoid
making
the
same
mistake
【解析】
没能：fail
to
do
sth.；避免：avoid
doing
sth.；重蹈覆辙：make
the
same
mistake。根据“crashing
on
the
way
to
Nairob”可知，这是非谓语动词，整个句子缺少谓语成分。结合句意，可知时态用一般过去时，故填failed
to
avoid
making
the
same
mistake。
39．Although
are
doing
【解析】
虽然：although，引导让步状语从句，句首首字母a大写；做：do，动词；根据句意，主句应用现在进行时，构成形式为：be
doing；主语“the
volunteers”是复数形式，be用are；do的现在分词是doing。故填Although；are；doing。
40．Although/Though
too
young
to
【解析】
“虽然”although/?though，引导让步状语从句，“太……而不能做某事”
too…to?do?sth.，是固定搭配，“小”young，形容词作表语。故填Although/Though；too；young；to。

cause
serious
problems
if
Japan
pours
the
nuclear
waste
water
into
the
sea.
The
waste
water
will
not
only
destory
the
homes
to
the
fish,
but
also
pollute
the
water
we
drink.
It’s
our
duty
to
protect
the
ocean.
First
of
all,
we
should
not
pour
the
rubbish
into
the
sea.
The
rubbish
will
pollute
the
ocean
and
make
the
fish
lose
their
homes.
Next,
we
need
to
clean
the
river
and
lake.
Last
but
not
least,
we
are
supposed
to
make
ships
environmentally
friendly.
It
is
helpful
to
the
ocean.
From
my
point
of
view,
we
should
stop
polluting
the
ocean
from
now
on.
We
all
need
to
raise
awareness
of
these
problems.
It
now
becomes
necessary
for
us
to
take
action
now,
before
it
is
too
late!
