[2019·合肥高三第二次质量检测]A
simple
project
to
help
a
family
in
need
stopped
Luke
Mickelson
in
his
tracks.
In
2012,
he
and
his
family
were
inspired
to
build
and
donate
a
bunk
bed,
one
bed
on
top
of
the
other,
after
learning
there
were
local
children
who
slept
on
the
floor.
Shocked
to
discover
how
widespread
this
need
was
in
his
community,
Mickelson
founded
Sleep
in
Heavenly
Peace,
a
nonprofit
that
builds
and
delivers
beds
to
children
in
need.
Born
and
raised
in
Idaho,
Mickelson,
now
41,
had
a
thriving
career.
He
coached
his
kids'
sports
teams
and
fished
in
the
nearby
river.
But
when
he
met
children
who
were
sleeping
on
the
floor,
his
peaceful
life
changed
course.
Using
safety
guidelines
and
his
daughter's
bunk
bed
as
a
model,
Mickelson
started
buying
wood
and
supplies
to
build
beds
with
his
own
money.
He
recruited
friends
and
family
members
to
help
around
the
holidays.
As
the
word
spread,
interest
and
involvement
from
his
and
other
communities
flooded
—
along
with
Mickelson's
bunk
bed
output.“That
first
project,
we
built
11
bunk
beds
in
my
garage，”
he
said.
“The
next
year,
we
did
15.
Then
it
doubled
every
year.
In
2017,
we
built
612
bunk
beds.”
With
the
motto“No
kid
sleeps
on
the
floor
in
our
town”，
the
nonprofit
and
its
more
than
65
branches
have
built
and
delivered
more
than
1,500
free
beds
to
children
across
America.
But
along
with
the
rapid
growth,
Mickelson
was
faced
with
a
tough
choice:
advancing
his
career
or
his
nonprofit.
He
chose
the
latter
and
went
from
making
“great
money
to
zero
money”.
He's
never
looked
back.
“I
found
that
the
need
I
have
isn't
financial，”
he
said.
“The
need
I
have
is
seeing
the
joy
on
kids'
faces,
knowing
that
I
can
make
a
difference.”
4．Why
did
Mickelson
set
up
Sleep
in
Heavenly
Peace?
A．To
help
the
poor
children.
B．To
make
a
big
fortune.
C．To
inspire
his
community.
D．To
get
more
donations.
5．What
do
we
know
about
Luke
Mickelson?
A．He
had
his
own
fish
farm.
B．He
changed
his
career
from
time
to
time.
C．He
used
to
sleep
on
the
floor
when
he
was
a
kid.
D．He
originally
had
a
relaxing
and
pleasant
life.
6．How

in
it.

and
involved
in
it.
C．They
were
doubtful
about
the
safety
of
the
bunk
bed.
D．They
volunteered
to
buy
beds
with
their

[2020·山西太原五中阶段检测]The
Arctic
Circle
—
the
habitat
of
polar
bears
and
decreasing
sea
ice
at
the
top
of
the
world
—
hit
32
degrees
Celsius
last
week.
This
was
the
temperature
in
Banak,
Norway
on
July
30,
though
some
Norwegian
areas
even
reached
a
couple
degrees
warmer,
according
to
the
European
Severe
Weather
Database.
Banak
sits
atop
northern
Europe,
over
350
miles
above
the
bottom
edge
of
the
Arctic
Circle.
The
Northern
Hemisphere
and
Europe
itself
have
been
repeatedly
scorched
by
both
record
and
near?record
temperatures
this
summer
as
a
consequence
of
overall
rising
global
temperatures.
In
the
past
40
years,
Earth's
climate
has
experienced
an
accelerated
warming
trend,
which
adds
an
extra
level
of
background
warming
to
hot
spells
—
making
heatwaves
more
extreme,
climate
scientists
have
said.
A
photo
of
what
appears
to
be

in
a
river
while
reindeer
—
the
cold?adapted
herbivores
(食草动物)
—
cooled
off
in
the
water
beside
them
is
perhaps
the
best
example
of
just
how
hot
it
is
in
parts
of
the
Arctic
Circle
right
now.
The“warm
season”
in
Banak
is
short,
lasting
around
three
months,
but
the
very
warmest
day
of
the
year,
around
July
23,
is
usually
around
62
degrees
Fahrenheit
(华氏度)
—
about
30
degrees
cooler
than
temperatures
there
now.
Overall,
temperatures
in
northern
Europe
are
between
14
to
21
degrees
Fahrenheit,
?10
to
?6
degrees
Celsius
above
average.
All?time
temperature
records
were
set
in
both
Norway
and
Finland
on
July
30,
including
86
degrees
Fahrenheit,
30
degrees
Celsius,
in
Cape
Verde,
near
Banak,
though
extreme
or
near?record
temperatures
blanketed
the
region.
Persistent
heat
and
dryness
this
summer
have
transformed
normally
green
European
countries
into
brown
and
yellow
lands,
and
the
continent's
extreme
heat
is
expected
to
persist.
Andrew
Derocher,
a
professor
at
the
University
of
Alberta
who
studies
polar
bears,
said
climate
change
is
shrinking
the
ice
bears
usually
hunt
on,
making
them
faced
with
the
danger
of
extinction.

[2019·山西六校第二次阶段性测试]World
Environment
Day
is
celebrated
annually
on
June
5th
and
was
created
to
inspire
people
around
the
globe
to
take
an
active
part
in
environmental
protection
and
learn
more
about
ways
we
can
help
to
guarantee
the
future
of
our
planet
is
safe.
The
very
first
World
Environment
Day
took
place
in
1974,
established
by
the
United
Nations
General
Assembly
on
the
first
day
of
the
Stockholm
Conference
on
the
Human
Environment
that
took
place
in
1972.
Each
year
the
United
Nations
pick
a
theme
and
a
host
city
where
anyone
who
is
concerned
about
the
environment
can
talk
about
environmental
topics
with
others,
followed
by
different
kinds
of
exhibits
to
promote
environmental
awareness.
Environmentalists,
academics
and
scientists
come
together
to
bring
new
ideas
on
the
table
concerning
the
environment.
The
2018
World
Environment
Day
is
hosted
by
India,
and
the
theme
is
Beat
Plastic
Pollution.
It
urges
people
to
explore
and
choose
supportable
alternatives
like
paper
or
cloth
bags
to
reduce
the
production
and
use
of
disposable
plastic,
which
makes
up
10%
of
all
of
the
waste.
Even
though
the
United
Nations
pick
a
specific
host
city
every
year,
people
around
the
world
still
celebrate
World
Environment
Day
in
their
hometowns
with
parades
(游行),
concerts,
cleaning
up
and
tree
planting
and
all
kinds
of
green
actions
to
work
towards
having
a
beautiful
planet
and
battling
pollution.
World
Environment
Day
is
not
a
public
holiday,
so
you
won't
be
getting
the
day
off
work
or
school,
but
if
you
want
to
celebrate,
why
not
bring
it
to
the
attention
of
your
parents,
friends,
colleagues
or
classmates?
World
Environment
Day
is
all
about
working
together
to
take
action
for
the
planet,
so
try
to
get
everyone
you
know
interested
in
helping
do
something.
Things
as
small
as
making
sure
people
have
a
way
to
recycle
can
make
a
difference.
You
could
also
try
beautifying
your
neighborhood
by
planting
gardens,
learn
about
green
foods,
raise
money
for
a
local
wildlife
conservation
group
or
simply
learn
about
the
effects
of
different
products
on
the
earth.
12．Why
is
World
Environment
Day
set
up?
A．To
make
people
know
more
about
nature.

[2020·重庆第一次调研]In

In

were

which

at

carried
them
home
and
__4__
them
out.
The

family
sifted
(筛)
and
sorted
them
according
to
their

and
then
transported
them
to
the
city
for
wholesale
or
retail.
Every
villager
knew
that
if
they
wanted
to
sell
for
a
good
price,
what
really
__6__
was
to
send
the
selected
chestnuts
to
the
market
first.
Many
families,
which

Still,
to

there
was
a
young
man
in
the
village
who
could
never
need
help,
__10__
he
had
limited
hands.
He
lived
with
his
blind
and
old
mother.
He
always
arrived
at

market
one

he
could
sell
out
of

chestnuts
and
then
happily
drove
back
with
his
truck

The
secret
of
the
young
man
was:
after
picking
chestnuts,
he
put
them
__13__
into
a
sack(麻袋)
and
carried
them
to
the
truck.
When
he
set
out,
he
chose
the
road,
__14__
and
bumpy
(不平的),
to
go,
__15__
the
small

would
jump
to
the
__16__
of
the
bag
and
the
larger
ones
would
stay
on
the
top
of
the
bag.
It
would
save

for
classification
and
selection.
When
inquired
how

way,
the
young
man
__17__
：“If
you
put

it,
you
will

in
Heavenly
Peace”。
4．A 考查细节理解。根据第一段中的“Mickelson

Sleep
in
Heavenly

a
nonprofit
that

and
delivers
beds
to
children
in
need”可知，Mickelson创建这个非盈利组织是为了帮助贫困儿童，故选A项。
5．D 考查推理判断。根据第二段中的“But

his
peaceful
life
changed
course”可推知，Mickelson一开始过着轻松、舒适的生活，故选D项。
6．B 考查细节理解。根据第三段中的“He
recruited
friends
and
family
members
to
help
around
the
holidays.
As
the
word
spread,
interest
and
involvement
from
his
and
other
communities
flooded”可知，Mickelson的朋友和其他家庭成员都来帮忙，随着消息的传播，更多人参与进来。由此可知，人们对Mickelson创建的这个组织非常支持，并且积极参与，故选B项。
7．D 考查推理判断。根据最后一段中的“The
need
I
have...
make
a
difference”可知，Mickelson想要看到孩子们脸上的喜悦的事情，他知道他在做一些有影响的事，由此可推知，他对这个组织持积极的态度，故选D项。
【语篇解读】 本文是一篇说明文，由于全球变暖的速度不断加快，作为北极熊栖息地的北极圈现在也面临着温度升高的状况。这样的环境变化对于北极熊的生存是很大的威胁。
8．A 考查词义猜测。根据第三段“The
Northern
Hemisphere
and
Europe
itself
have
been
repeatedly
scorched
by
both
record
and
near?record
temperatures...”可知，今年夏天，由于全球气温总体上升，北半球和欧洲自身不断受到创纪录和接近创纪录气温的炙烤。因此，画线词的意思是“烧伤；烧焦”，故选A项。
9．D 考查细节理解。根据第五段“A
photo
of
what
appears
to
be
Scandinavian
folks
taking
a
dip
in
a
river...
is
in
parts
of
the
Arctic
Circle
right
now.”可知，喜冷的食草动物在水里凉快，证明了北极圈开始变热。因此，这张照片表明现在北极圈的温度很高，故选D项。
10．B 考查推理判断。根据最后一段“Andrew
Derocher...
said
climate
change
is
shrinking
the
ice
bears
usually
hunt
on,
making
them
faced
with
the
danger
of
extinction.”可知，气候变暖使得北极熊赖以生存的冰面减小，致使北极熊面临灭绝的危险。因此，从德罗彻教授的话中可以得知气候变化正威胁着北极熊(的生命安全)，故选B项。
11．B 考查推理判断。根据第一段“The
Arctic
Circle
—
the
habitat
of
polar
bears
and
decreasing
sea
ice
at
the
top
of
the
world
—
hit
32
degrees
Celsius
last
week.”可知，这篇文章是报道上周北极圈温度达到32摄氏度的新闻。因此，本文不可能出现在时尚杂志、地理教科书或旅游手册中，它最有可能出现在新闻报道中，故选B项。
【语篇解读】 本文是一篇说明文，介绍了世界环境日的由来和情况，呼吁全员行动起来帮助保护地球。
12．B 考查细节理解。根据第一段中的“to

an
active
part
in
environmental
protection
and
learn
more
about
ways

together
to
bring
new
ideas
on
the
table
concerning
the
environment”可知，人们主要是在这一天讨论环境问题，故选C项。

Plastic
Pollution”可知，2018年的主题是“塑战速决”，再结合画线词前面的“It
urges
people
to
explore
and
choose
supportable
alternatives
like
paper
or
cloth
bags”和后面的“which
makes
up
10%
of
all
of
the
waste”可知，“disposable
plastic”造成大量资源浪费，所以“一次性的”符合语境，故选D项。
15．A 考查主旨大意。根据最后一段的内容可知，世界环境日不是公共节日，所以人们不放假。但如果你想庆祝的话，为何不让你周围的人关注它。所以最后一段主要是讲每个人都可以从身边小事做起，行动起来保护地球，每个人的微小努力都很重要，故选A项。
第二节
【语篇解读】 本文是一篇说明文，从四个方面阐述学生在校园中如何节约能源、保护环境。
1．B 根据句子的结构判断，本句是一个从句，七个选项中只有B、C和G三个选项符合要求。根据语境可知，此处表示“不管你是老师还是学生，总有许多可以帮助你们学校节约能源的方法”，故答案为B。
2．E 本段主要讲述在离开教室等地方的时候关灯以便节约能源。本段中的一些提示词，如“turning
off
the
lights”“Turn
off
the
lights”等也暗示了本题的答案，故选E项。
3．F 本段主要讲述当教室内光线充足时使用自然光。空前句子中的“times
of
day”与F项中的“Other
times
of
day”形成对应关系，故选F项。

recycling
station”，故选C项。

7．or 考查连词。根据语境可知，此处表示“或者”，故用表示选择关系的连词or。
8．have
had 考查动词的时态和主谓一致。根据本句中的“Since”可知，主句应用现在完成时，表示过去发生的动作对现在造成的影响，主语为we，且与have为主动关系，故填have
had。
9．weekly 考查形容词。根据空前的冠词a和空后的名词basis可知，此处应用形容词，填weekly。

①long改为longer no
longer为固定搭配，意为“不再”，符合语境。
②advantage改为advantages advantage为可数名词，根据该句中的复数可数名词“drawbacks”可知，该处与此呼应，也应当用复数形式。该句意为：然而，住在那里有缺点，也有优点。
③crowding改为crowded 该句意为：从积极的方面来说，人们将能够逃离拥挤的城市，并能清楚地看到地球和星星。该处表示“拥挤的”，用形容词crowded。crowding为动名词形式，不是形容词。
④but改为and 句意参见上题。根据句意可知，此处前后部分在逻辑上为并列关系，不是转折关系，故用连词and。
⑤a改为an 该句意为：另一方面，月球对人类来说是一个不友好的地方。此处表示“一个不友好的地方”，故用不定冠词；且unfriendly的发音以元音音素开头，故用an。
⑥it改为they 该句意为：首先，人们将不得不穿特殊的服装，如果他们的设备发生故障，则他们有可能会死亡。根据该句主语people可知，该处用they。
⑦be改为being get
used
to
doing
sth.为固定搭配，意为“习惯于做某事”，故用being。该句意为：其次，他们必须习惯失重状态。
⑧exists改为exist 该句意为：最后，他们很可能会想念地球上存在的植物和野生生物。根据句意可知，从句陈述的是客观事实，故用一般现在时；该句中that为定语从句的引导词，作主语，指代“the
plants
and
wildlife”，为复数形式，故谓语动词用exist。
⑨删除over take
a
holiday为固定搭配，意为“度假”，故可知答案；take
over意为“接管”，与语境不符。
⑩live后加in 该句意为：总之，月球可能是人类度假或科学家进行研究的理想场所，但不是普通人一直生活的地方。该处表示“在……上生活”，故用介词in。

I
