Ⅱ.阅读理解
A
serious
problem
for
today's
society
is
who
should
be
responsible
for
our
elderly
and
how
to
improve
their
lives.
It
is
not
only
a
financial
problem
but
also
a
question
of
the
system
we
want
for
our
society.
I
would
like
to
suggest
several
possible
solutions
to
this
problem.
First,
employers
should
take
the
responsibility
for
their
retired
employees.
To
make
this
possible,
a
percentage
of
profits
should
be
set
aside
for
this
purpose.
But
when
a
company
must
take
life?long
responsibility
for
its
employees,
it
may
suffer
from
a
commercial
disadvantage
due
to
higher
employee
costs.
Another
way
of
solving
the
problem
is
to
return
the
responsibility
to
the
individual.
This
means
each
person
must
save
during
his
working
years
to
pay
for
his
years
of
retirement.
This
does
not
seem
a
very
fair
model
since
some
people
have
enough
trouble
paying
for
their
daily
life
without
trying
to
earn
extra
to
cover
their
retirement
years.
This
means
the
government
might
have
to
step
in
to
care
for
the
poor.
In
addition，the
government
could
take
responsibility
for
the
care
of
the
elderly.
This
could
be
financed
through
government
taxes
to
increase
the
level
of
pensions.
Furthermore,
some
institutions
should
be
created
for
senior
citizens,
which
can
help
provide
a
comfortable
life
for
them.
Unfortunately,
as
the
present
situation
in
our
country
shows,
this
is
not
a
truly
viable
answer.
The
government
can
seldom
afford
to
care
for
the
elderly,
particularly
when
it
is
busy
trying
to
care
for
the
young.
One
further
solution
is
that
the
government
or
social
organizations
establish
some
working
places
especially
for
the
elderly
where
they
are
independent.
To
sum
up,
all
these
options
have
advantages
and
disadvantages.
Therefore,
it
is
reasonable
to
expect
that
some
combination
of
these
options
may
be
needed
to
provide
the
care
we
hope
to
give
to
our
elderly
generations.

an
important
social
problem.
B．To

the
need
for
government
support
for
old
people.
D．To
instruct
retired
people
on
how
they
can
have
a
happier

2．What
does
the
underlined
word
“viable”
in
Paragraph
3
most
probably
mean?
A．impossible.
B．practical.
C．useful.
D．successful.
3．According
to
the
passage,
how
can
the
government
help
to
improve
the
lives
of
retired
people?
A．Set
aside
some
profits
to
help
people
with
problems
after
they
retire.
B．Increase
savings
levels
of
people
during
their
working
years.
C．Increase
the
discounts
for
food
and
transport
for
the
old.
D．Make
available
pensions
for
those
who
have
retired.
4．What
can
be
concluded
from
the
passage?
A．Taking
care
of
the
old
is
mainly
an
issue
of
money.
B．Employers
should
allow
their
workers
to
retire
at
a
later
age.
C．Becoming
independent
should
be
the
goal
of
most
old
people.
D．There
is
no
single
solution
to
the
problems
of
the
old.

serious
problem
for
today's
society
is
who
should
be
responsible
for
our
elderly
and
how
to
improve
their
lives.，然后后面段落给出一些改善老人生活的建议，故可以推断出，作者写此文目的是为了讨论一些重要社会问题的可能解决办法。故选A。
2．答案与解析：B 词义猜测题。根据第三段最后一句The
government
can
seldom
afford
to
care
for
the
elderly,
particularly
when
it
is
busy
trying
to
care
for
the
young.可知，由于政府忙于照顾小的，没有资金照顾老人，所以这措施是行不通的，没有可操作性。从而可以猜测viable为“可行的”之意。故选B。
3．答案与解析：D 细节理解题。根据句子This
could
be
financed
through
government
taxes
to
increase
the
level
of
pensions可知，政府可以通过给退休人员养老金来提高他们的生活，故答案为D。
4．答案与解析：D 推理判断题。文章第二至第五段提出了五种提高老人生活质量的建议，最后一段To

1．答案与解析：G 关联逻辑法解题。本空前文说在繁忙的生活中，我们很难找到时间锻炼，后文说晨练的好处，故中间的衔接句可表达“假设有时间锻炼”之类的含义，因此G项符合语境。本设空类型为过渡句类。
2．答案与解析：E 句意判断法解题。本段的主旨是“晨练能提高你的效率”，E项“锻炼之后的4到10小时内，你都能让自己头脑清醒。”追加了锻炼的好处，符合此处的语境。本设空类型为细节理解类。
3．答案与解析：F 词汇锁定法解题。这一段说的是晨练有助于人体的新陈代谢，能让你一整天都感受到晨练消耗卡路里带来的好处，F项意为“晨练之后你还会在一天时间里继续消耗卡路里”。F项中的关键词throughout
the
day与文中的the
whole
day呼应。故选F。本设空类型为细节理解类。
4．答案与解析：B 词汇锁定法解题。本题考查段落主题。本段提到“slept
better，difficult
to
relax，a
peaceful
sleep”，因此这一段说的是晨练比晚上锻炼更能改善睡眠，因此选B。本设空类型为段落主题句类。

to
healthy
food
choices,

When
Sally
Millsopp,
53,
with
her
17?year?old
daughter,
Eleanor,
participated
in
Race
for
Life
in
2019.
She
had
no
idea
if
she
would
get
to
see
her
mother
Jennifer
Earnshaw
again,
who
was
desperately
ill
with
a
form
of
lung
cancer,
but
she
encouraged
the
pair
to
take
part
in
the
event
as
she
knew
the
fundraising
would
help
others.
They
managed
to
make
it
back
to
her
bedside
just
in
time
to
show
her
the
photographs.
Jennifer,
who
was
a
former
head
teacher,
passed
away
the
following
day,
aged
76.
Ms
Millsopp
and
her
daughter
are
once
again
participating
in
the
Race
for
Life
on
May
13
this
year
to
the
memory
of
Jennifer,
and
will
be
speaking
on
stage
to
inspire
others.
“Mum
was
a
selfless
person.
I
knew
she
really
wanted
us
to
do
Race
for
Life
but
it
was
hard
not
knowing
if
I
would
be
there
with
her
at
the
end.
When
we
reached
the
finish
line,
Eleanor
and
I
both
felt
elated
that
we'd
done
something
so
positive
at
such
a
sad
time.
We
had
a
big
hug
and
knew
it
was
something
Mum
would
be
proud
of，”
said
Ms
Millsopp.
One
in
two
people
in
the
UK
will
be
diagnosed
with
cancer,
but
the
good
news
is
more
people
are
surviving
the
disease
now
than
ever
before.
Cancer
Research
UK's
Race
for
Life,
in
partnership
with
Tesco,
is
an
inspiring
women—only
series
of
5k,
10k,
Pretty
Muddy
and
Hiking
events
which
raise
millions
of
pounds
every
year
to
help
beat
cancer
sooner
by
funding
vital
research.
Gemma
Turpin,
Cancer
Research
UK's
Norwich
event
manager,
said,
“We
are
very
grateful
to
Sally
and
Eleanor
for
their
story
that
highlights
how
special
Race
for
Life
is
to
people.
By
following
them,
women
in
Norfolk
can
make
a
real
difference
in
the
fight
against
cancer.
Money
raised
through
Race
for
Life
is
helping
beat
over
200
different
types
of
cancer—that's
why
every
step,
every
person
and
every
penny
raised
counts.”

Ⅲ.七选五
The
dictionary
isn't
forever.
What
happens
to
a
word
when
its
popularity
starts
to
decline?
Here's
how
the
process
of
deleting
a
word
from
the
dictionary
works.
The
dictionary
is
actually
a
steadily
enlarging
volume.
__1__
New
words
arise
from
emerging
and
expanding
disciplines.
Definitions
also
change
and
shift,
so
common
words
gain
new
meanings.
On
the
other
hand,
there
are
also
words
that
become
outdated.
__2__
Who
decides
which
words
to
delete?
__3__
While
adding
a
word
to
the
dictionary
is
a
precise
process,
it's
even
more
difficult
for
a
word
to
get
deleted.
Editors
maintain
and
study
vast
language
databases
to
keep
up?to?date
on
the
words
in
circulation
across
various
media.
The
Oxford
English
Dictionary
covers
the
English
language
over
the
last
1,000
years,
and
it's
considered
definitive
and
authoritative.
__4__
And
each
has
its
own
process
for
additions
and
removals.
__5__
A
2019
petition
(请愿)
with
30,000
signatures
calls
for
The
Oxford
English
Dictionary
to
remove
sexist
language
and
definitions,
especially
those
terms
under
the
word
“woman”.
And
Merriam?Webster
recently
changed
definitions
of
identity—related
words
to
reflect
new
cultural
meanings
around
fairness.
A．Some
new
words
might
be
out
of
date
one
day.
B．As
a
result,
words
get
removed
from
the
dictionary.
C．Dictionary
additions
and
deletions
reflect
social
changes.
D．It's
up
to
the
dictionary
editors
to
make
the
final
decision.
E．That's
because
the
English
language
constantly
develops
and
changes.
F．These
are
often
the
types
of
words
that
will
make
it
into
dictionaries.
G．However,
there
are
many
other
dictionaries
that
are
reliable
and
trustworthy.

Ⅲ.七选五
【语篇解读】 这是一篇说明文。文章主要说明了英语是不断发展和变化的。新词汇产生于新兴和拓展的学科，定义也会变化，所以常用词有了新的含义。另一方面，有些词也会过时。结果，有些单词就从字典中删除了。文章说明了从字典中删除一个单词的过程。
1．答案与解析：E 根据前文“The
dictionary

2．答案与解析：B 根据前文“On
the
other
hand,
there
are
also
words
that
become
outdated.(另一方面，有些词也会过时。)”可推测本句说明一些词过时的结果。结果就是这些单词被从字典中删除。故B选项“结果，单词就从字典中删除了。”符合上下文语境。故选B。
3．答案与解析：D 根据前文“Who
decides
which
words
to
delete？(谁来决定删除哪些单词。)”上文提出问题，故本空应是对上文谁决定删除那些单词的回答。故D选项“词典的最终决定权在编辑手中。”符合上下文语境。故选D。
4．答案与解析：G 根据前文“The
Oxford
English
Dictionary
covers
the

for
additions
and
removals.(每个都有自己的添加和移除流程。)”可推知本句是说明除了《牛津英语词典》之外，其他许多可靠的字典也有自己的添加和移除单词的流程。故G选项“然而，有许多其他的字典是可靠的和值得信赖的。”符合上下文语境。故选G。
5．答案与解析：C 根据下文“A

Ⅱ.阅读理解
By
the
end
of
the
century,
if
not
sooner,
the
world's
oceans
will
be
bluer
and
greener
thanks
to
a
warming
climate,
according
to
a
new
study.
At
the
heart
of
the
phenomenon
lie
tiny
marine
microorganisms
(海洋微生物)
called
phytoplankton.
Because
of
the
way
light
reflects
off
the
organisms,
these
phytoplankton
create
colourful
patterns
at
the
ocean
surface.
Ocean
colour
varies
from
green
to
blue,
depending
on
the
type
and
concentration
of
phytoplankton.
Climate
change
will
fuel
the
growth
of
phytoplankton
in
some
areas,
while
reducing
it
in
other
spots,
leading
to
changes
in
the
ocean's
appearance.
Phytoplankton
live
at
the
ocean
surface,
where
they
pull
carbon
dioxide
(二氧化碳)
into
the
ocean
while
giving
off
oxygen.
When
these
organisms
die,
they
bury
carbon
in
the
deep
ocean,
an
important
process
that
helps
to
regulate
the
global
climate.
But
phytoplankton
are
vulnerable
to
the
ocean's
warming
trend.
Warming
changes
key
characteristics
of
the
ocean
and
can
affect
phytoplankton
growth,
since
they
need
not
only
sunlight
and
carbon
dioxide
to
grow,
but
also
nutrients.
Stephanie
Dutkiewicz,
a
scientist
in
MIT's
Center
for
Global
Change
Science,
built
a
climate
model
that
projects
changes
to
the
oceans
throughout
the
century.
In
a
world
that
warms
up
by
3
℃，
it
found
that
multiple
changes
to
the
colour
of
the
oceans
would
occur.
The
model
projects
that
currently
blue
areas
with
little
phytoplankton
could
become
even
bluer.
But
in
some
waters,
such
as
those
of
the
Arctic,
a
warming
will
make
conditions
riper
for
phytoplankton,
and
these
areas
will
turn
greener.
“Not
only
are
the
quantities
of
phytoplankton
in
the
ocean
changing，”
she
said,
“but
the
type
of
phytoplankton
is
changing.”
And
why
does
that
matter?
Phytoplankton
are
the
base
of
the
food
web.
If
certain
kinds
begin
to
disappear
from
the
ocean,
Dutkiewicz
said,
“it
will
change
the
type
of
fish
that
will
be
able
to
survive.”
Those
kinds
of
changes
could
affect
the
food
chain.
Whatever
colour
changes
the
ocean
experiences
in
the
coming
decades
will
probably
be
too
gradual
and
unnoticeable,
but
they
could
mean
significant
changes.
“It'll
be
a
while
before
we
can
statistically
show
that
the
changes
are
happening
because
of
climate
change，”
Dutkiewicz
said,
“but
the
change
in
the
colour
of
the
ocean
will
be
one
of
the
early
warning
signals
that
we
really
have
changed
our
planet.”
1．What
are
the
first
two
paragraphs
mainly
about?
A．The
various
patterns
at
the
ocean
surface.
B．The
cause
of
the
changes
in
ocean
colour.
C．The
way
light
reflects
off
marine
organisms.
D．The
efforts
to
fuel
the
growth
of
phytoplankton.
2．What
does
the
underlined
word“vulnerable”in
Paragraph
3
probably
mean?
A．Sensitive.
B．Beneficial.
C．Significant.
D．Unnoticeable.
3．What
can
we
learn
from
the
passage?
A．Phytoplankton
play
a
declining
role
in
the
marine
ecosystem.
B．Dutkiewicz's
model
aims
to
project
phytoplankton
changes.
C．Phytoplankton
have
been
used
to
control
global
climate.
D．Oceans
with
more
phytoplankton
may
appear
greener.
4．What
is
the
main
purpose
of
the
passage?
A．To
assess
the
consequences
of
ocean
colour
changes.
B．To
analyse
the
composition
of
the
ocean
food
chain.
C．To
explain
the
effects

9．that 10.that
Ⅱ.阅读理解
【语篇解读】 本文是一篇说明文。调查表明，由于气候变暖，全球的海洋将会变得更蓝、更绿。
1．答案与解析：B 段落大意题。文章第一段点题：由于气候变暖，全球的海洋将会变得更蓝、更绿。第二段介绍由于光从生物体反射的方式，这些浮游植物在海洋表面形成了五颜六色的图案；气候变化又使得这些浮游植物在某些区域加速生长而在其他地方有所减少，导致海洋表面的颜色变化。由此可知前两段讲了海洋颜色变化的原因，故B项正确。
2．答案与解析：A 词义猜测题。后一句提到，气候变暖改变了海洋的主要特点并能影响浮游植物的生长，因为它们要生长不仅仅需要阳光和二氧化碳，也需要营养。由此可知，这些浮游植物对海洋变暖很敏感，故A项正确。
3．答案与解析：D 推理判断题。文章倒数第二段提到这些浮游植物是海洋食物链的基础，如果某些种类的浮游植物消失了，会影响能存活的鱼的类型，从而影响海洋食物链，所以A项“浮游植物在海洋生态中所起的作用越来越小。”是不对的；Dutkiewicz的模型不是用来推断浮游植物的变化的，而是推断海洋的变化的，排除B项；浮游植物不是用来控制全球气候的，排除C项。由文章第四段信息“But
in
some
waters，such
as
those
of
the
Arctic，a
warming
will
make
conditions
riper
for
phytoplankton，and
these
areas
will
turn
greener.”可知浮游植物多的区域海水会变得更绿，故D项正确。
4．答案与解析：C 主旨大意题。文章主要论述了随着气候变暖，全球的海洋将会变得更蓝、更绿，即气候变化对海洋有影响，故C项正确。
