Ⅰ.阅读理解
A
When
I
was
in
the
third
grade,
we
had
a
hunt
at
school.
We
gathered
up
chalk，pencils，stones,
and
so
on,
rapidly
filling
our
checklists.
It
was
a
very
close
race.
I
was
out
of
breath
when
I
reached
the
clover
(三叶草)
patch
in
search
of
the
last,
most
hard to find
item:
a
four leaf
clover.
I
was
pretty
sure
that
I
was
going
to
win.
I
have
always
been
able
to
find
four leaf
clovers.
I
just
saw
them.
I
spent
my
childhood
collecting
and
pressing
four leaf
clovers
into
books
at
my
mother's
house.
I
started
with
big
cloth
and
leather bound
books.
When
I
ran
out
of
romantically
bound
volumes,
I
began
to
put
my
treasures
into
anything
I
could
find:
fiction
paperbacks
and
cookbooks.
The
same
is
true
in
my
house
today.
Shake
a
book,
and
a
papery
treasure
just
might
fall
into
your
hand.
A
few
years
ago,
in
Nova
Scotia,
my
husband
and
I
pulled
off
the
road
for
a
picnic.
The
ground
was
thick
with
clover.
Some
shoots
had
four,
five,
even
six
leaves.
I
lined
them
up
on
the
picnic
table
to
admire
as
my
husband,
never
yet
having
found
one
four leaf
clover,
looked
on
in
awe.
To
me,
it
was
simple.
The
differences
in
their
shapes
popped
out,
breaking
the
pretty
pattern
of
the
conventional
clover
with
their
three
perfect
leaves.
Two
summers
back,
while
waiting
for
an
airport
shuttle
in
Munich,
I
found
a
tiny
four leaf
clover
in
a
traffic
circle
and
put
it
into
my
passport.
On
the
way
home,
my
husband
and
I
were
upgraded
to
business
class.
Friends
attributed
our
good
luck
to
the
clover.
I
think,
it's
more
likely
that
we
were
upgraded
because
a
kind
customer
service
officer
took
pity
on
us.
People
disagree
about
whether
the
luck
lies
in
the
finding
or
in
the
possession
of
a
four leaf
clover.
Some
believe
that
the
luck
is
lost
if
the
four leaf
clover
is
even
shown
to
somebody
else,
while
others
think
the
luck
doubles
if
it
is
given
away.
I
believe
that
positivity
is
increased
by
sharing.
I
feel
lucky
to
find
the
clovers
so
often,
but
I
don't
think
they
influence
my
life
any
more
than
it
does
to
share
anything
a
little
special—that
momentary
closeness
between
you
and
a
friend
or
a
stranger,
as
you
all
lean
in
to
wonder
at
a
rare
find.
1．Why

the
author
notice
four leaf
clovers
so
easily
A．She
always
has
good
luck.
B．She
has
a
special
gift
for
plants.
C．She
practiced
a
lot
in
her
childhood.
D．She
can
tell
the
pattern
differences.
2．How
does
the
author
deal
with
her
four leaf
clovers
A．She
often
gives
them
away.
B．She
leaves
them
everywhere.
C．She
treats
them
with
special
love.
D．She
admires
them
with
her
husband.
3．How
does
the
author
understand
luck
and
clovers
A．The
closeness
brought
by
clovers
really
counts.
B．Clovers
will
influence
one's
good
luck
a
lot.
C．Good
luck
means
finding
or
owning
a
clover.
D．Good
luck
may
double
if
you
give
clovers
away.
4．What
may
be
the
best
title
for
the
passage
A．Hunting
clovers
B．Sharing
clovers
C．Not
just
for
luck
D．Just
for
luck
B
A
dragonfly
barely
an
inch
and
a
half
long
appears
to
be
the
animal
world's
most
productive
long
distance
traveler—flying
thousands
of
miles
over
oceans
as
it
migrates
from
continent
to
continent—according
to
a
newly
published
research.
Biologists
who
led
the
study
say
the
evidence
is
in
the
genes.
They
found
that
populations
of
this
dragonfly,
called
Pantala
flavescens,
in
Texas,
eastern
Canada,
Japan,
Korea,
India,
and
South
America,
have
genes
so
similar
that
there
is
only
one
likely
explanation.
Apparently—somehow—these
insects
are
traveling
distances
that
are
extraordinarily
long
for
their
small
size,
breeding
(繁殖)
with
each
other,
and
creating
a
common
worldwide
gene
pool.
But
how
do
insects
from
different
continents
manage
to
meet
and
hook
up
Ware
says
it
appears
to
be
the
way
their
bodies
have
evolved.
“These
dragonflies
have
adaptations
such
as
increased
surface
areas
on
their
wings
that
enable
them
to
use
the
wind
to
carry
them.”
Dragonflies,
in
fact,
have
already
been
observed
crossing
the
Indian
Ocean
from
Asia
to
Africa.
“They
are
following
the
weather，”
says
Daniel
Troast,
who
analyzed
the
DNA
samples
in
Ware's
lab.
“They're
going
from
India
where
it's
the
dry
season
to
Africa
where
it's
the
wet
season,
and
apparently
they
do
it
once
a
year.”
Wetness
is
a
must
for
Pantala
to
reproduce,
and
that
,
says
Ware,
is
why
these
insects
would
be
driven
to
even
attempt
such
a
dangerous
trip,
which
she
calls
a
“kind
of
suicide.”
The
species
depends
on
it.
While
many
will
die
on
the
route,
as
long
as
enough
make
it,
the
species
survives.
For
the
moment,
the
details
of
this
extraordinary
insect
travel
are
a
best
educated
guess.
Much
more
work
is
needed
to
bring
many
loose
ends
together.
Ware
and
Troast
hope
that
scientists
can
work
on
plotting
those
routes.
5．What
proves
Pantala
flavescens
are
the
world's
longest distance
flyers
A．Scientists
have
tracked
the
dragonfly
across
the
world.
B．There
are
many
Pantala
flavescens
in
various
continents.
C．The
same
dragonfly
was
found
both
in
Asia
and
America.
D．Pantala
flavescens
in
different
continents
have
similar
genes.
6．What
helps
Pantala
flavescens
fly
over
so
long
distance
A．Their
special
body
shape.
B．Their
ability
to
use
wind.
C．Their
small
and
light
bodys.
D．Their
large
and
strong
wings.
7．What
is
necessary
for
Pantala
flavescens
to
reproduce
A．Damp
weather.
B．Enough
sunshine.
C．Dry
environment.
D．Warm
nests.
8．What
does
the
underlined
word
“it”
in
Paragraph
5
refer
to
A．The
weather.
B．The
insect.
C．The
wind.
D．The
trip.
Ⅱ.七选五
The
American
book
Who
Moved
My
Cheese
has
been
a
best
seller
all
over
the
world.
It
tells
a
story
which
happened
between
mice
and
people.
__1__
The
book
tells
us
that
when
facing
changes
in
our
lives,
like
a
new
school
or
new
friends,
don't
be
afraid.
__2__
The
book
gives
an
example
of
a
change
at
school.
A
school
is
changing
from
having
two
terms
to
three
terms
because
there
are
too
many
students.
Several
teenagers
are
talking
about
this.
Most
of
them
are
unhappy
and
worried.
But
Chris
laughs
and
tells
a
story
about
two
mice,
two
“little
people”
and
some
cheese.
The
four
are
in
a
maze
(迷宫)
looking
for
the
cheese.
Here,
cheese
means
something
important
in
life,
like
moving
to
a
new
class
or
getting
into
college.
__3__
The
mice
realize
that
they
can't
change
what
has
happened
and
have
to
find
more
cheese.
This
means
finding
different
dreams.
The
little
people,
however,
can't
do
this.
__4__
After
Chris
finishes
the
story,
his
friends
understand
one
thing:
__5__
His
friends
understand
how
this
can
be
used
in
the
changes
all
teenagers
face,
such
as
doing
well
at
school
or
having
good
relationships
or
just
feeling
good
about
yourself.
A．I
bought
one
last
week
and
found
it
very
interesting.
B．Instead,
use
these
changes
to
make
a
better
life.
C．However,
some
strange
things
happened
in
a
school.
D．Its
author
Spencer
Johnson
has
written
the
book
just
for
teenagers.
E．To
get
more
cheese,
move
in
a
new
direction
quickly.
F．But
they
find
the
cheese
is
gone.
G．They
are
afraid
of
changes
so
they
find
no
cheese.
详解答案
Ⅰ.阅读理解
A
【语篇解读】 文章属于记叙文。作者从小到大一直喜欢收集四叶草，并能够比别人更容易地找出四叶草。有些人认为，如果四叶草被展示给别人看，运气就会丧失；而另一些人则认为，如果将四叶草送给别人，运气就会加倍。作者相信分享会增加积极性，找到四叶草并和别人分享的那种亲密感才是重要的。
1．答案与解析：D 细节理解题。由第四段中To
me,
it
was
simple.
The
differences
in
their
shapes
popped
out,
breaking
the
pretty
pattern
of
the
conventional
clover
with
their
three
perfect
leaves.可知，它们形状的差异会突显出来，打破了传统三叶草美丽的形状。所以作者能辨别三叶草和四叶草的形状的区别。
2．答案与解析：C 推理判断题。由第三段可以看出作者非常乐于收集四叶草；第五段中介绍了作者在机场看见一片小的四叶草也会夹在护照里；在作者眼中，四叶草是她的“treasure”并乐于向丈夫、朋友分享。由此可以判断出作者对四叶草有着特别的爱。
3．答案与解析：A 细节理解题。由最后一段中I
don't
think
they
influence
my
life
any
more
than
it
does
to
share
anything
a
little
special—that
momentary
closeness
between
you
and
a
friend
or
a
stranger,
as
you
all
lean
in
to
wonder
at
a
rare
find.判断出作者认为四叶草带来的亲密感才是重要的。
4．答案与解析：C 主旨大意题。作者通过自己的经历，旨在表达并不只是四叶草能带来幸运，找到四叶草并和别人分享的那种亲密才是最重要的。故C选项“不只是运气”为短文的最佳标题。
B
【语篇解读】 文章属于说明文，介绍了一种长途飞行的蜻蜓Pantala
flavescens。这种蜻蜓冒险长途飞行的原因是它的繁殖需要湿润的气候。
5．答案与解析：D 推理判断题。根据第二段内容可知，领导这项研究的生物学家说基因就是证据。Pantala
flavescens蜻蜓在不同的洲有可能留有后代，才会有相似的基因。反过来，在不同的洲有共同的基因，证明了它们曾飞到过那儿，也就证明了这种蜻蜓是长途飞行者。
6．答案与解析：B 推理判断题。根据第三段中的These
dragonflies
have
adaptations
such
as
increased
surface
areas
on
their
wings
that
enable
them
to
use
the
wind
to
carry
them.可知这些蜻蜓适应性强，比如翅膀上表面积的增加，使它们能够利用风来飞行。故B项(运用风飞行的能力)正确。
7．答案与解析：A 细节理解题。根据第五段首句中的Wetness
is
a
must
for
Pantala
to
reproduce可知这种蜻蜓的繁殖必须要湿润的气候。
10．答案与解析：D 推理判断题。根据第五段内容可知，对于这种昆虫来说，这种危险的旅行是自杀式行为。虽然许多昆虫会死在途中，但这种物种依靠这种旅行生存下来。从后面一句While
many
will
die
on
the
route,
as
long
as
enough
make
it,
the
species
survives.可知，it指的是上文的危险旅行。
Ⅱ.七选五
【语篇解读】 文章属于说明文。介绍了一本美国畅销书《谁动了我的奶酪》。
1．答案与解析：D 前文提到“《谁动了我的奶酪》讲述了一个发生在老鼠和人之间的故事。”是该书的内容简介，D选项“该书的作者斯宾塞·约翰逊专为青少年写了这本书。”为作者的介绍，与前文对应。故选D项。
2．答案与解析：B 前文提到“这本书告诉我们，当我们面对生活中的变化时，比如新学校或新朋友，不要害怕”，B项“相反，利用这些变化来创造更好的生活。”与前文的内容衔接自然，“changes”与前文呼应。故选B项。
3．答案与解析：F 前文提到“在这里，奶酪意味着生活中重要的事情，比如搬到一个新的班级或进入大学。”指生活中出现了新变化，奶酪自然就不见了，后文又提到“必须找到更多的奶酪”。F项“但是他们发现奶酪不见了。”承上启下。故选F项。
4．答案与解析：G 上句提到“小矮人做不到这个”，G项“他们害怕变化，所以找不到奶酪。”解释前句小矮人找不到奶酪的原因。故选G项。
5．答案与解析：E 根据设空处前文可知，此处总结文章主旨，结合全文的启示，在生活中遇到变化时，我们需要快速融入环境。E项“为了得到更多的奶酪，快速地朝新的方向前进。”与文章的主旨相对应。故选E项。

Ⅱ.七选五
The
American
book
Who
Moved
My
Cheese
has
been
a
best
seller
all
over
the
world.
It
tells
a
story
which
happened
between
mice
and
people.
__1__
The
book
tells
us
that
when
facing
changes
in
our
lives,
like
a
new
school
or
new
friends,
don't
be
afraid.
__2__
The
book
gives
an
example
of
a
change
at
school.
A
school
is
changing
from
having
two
terms
to
three
terms
because
there
are
too
many
students.
Several
teenagers
are
talking
about
this.
Most
of
them
are
unhappy
and
worried.
But
Chris
laughs
and
tells
a
story
about
two
mice,
two
“little
people”
and
some
cheese.
The
four
are
in
a
maze
(迷宫)
looking
for
the
cheese.
Here,
cheese
means
something
important
in
life,
like
moving
to
a
new
class
or
getting
into
college.
__3__
The
mice
realize
that
they
can't
change
what
has
happened
and
have
to
find
more
cheese.
This
means
finding
different
dreams.
The
little
people,
however,
can't
do
this.
__4__
After
Chris
finishes
the
story,
his
friends
understand
one
thing:
__5__
His
friends
understand
how
this
can
be
used
in
the
changes
all
teenagers
face,
such
as
doing
well
at
school
or
having
good
relationships
or
just
feeling
good
about
yourself.
A．I
bought

last
week
and

find
the
cheese
is
gone.

详解答案
Ⅰ.阅读理解
A
【语篇解读】 文章属于记叙文。作者从小到大一直喜欢收集四叶草，并能够比别人更容易地找出四叶草。有些人认为，如果四叶草被展示给别人看，运气就会丧失；而另一些人则认为，如果将四叶草送给别人，运气就会加倍。作者相信分享会增加积极性，找到四叶草并和别人分享的那种亲密感才是重要的。
1．答案与解析：D 细节理解题。由第四段中To
me,
it
was
simple.
The
differences
in
their
shapes
popped
out,
breaking
the
pretty
pattern
of
the
conventional
clover
with
their
three
perfect
leaves.可知，它们形状的差异会突显出来，打破了传统三叶草美丽的形状。所以作者能辨别三叶草和四叶草的形状的区别。
2．答案与解析：C 推理判断题。由第三段可以看出作者非常乐于收集四叶草；第五段中介绍了作者在机场看见一片小的四叶草也会夹在护照里；在作者眼中，四叶草是她的“treasure”并乐于向丈夫、朋友分享。由此可以判断出作者对四叶草有着特别的爱。
3．答案与解析：A 细节理解题。由最后一段中I
don't
think
they
influence
my
life
any
more
than
it
does
to
share
anything
a
little
special—that
momentary
closeness
between
you
and
a
friend
or
a
stranger,
as
you
all
lean
in
to
wonder
at
a
rare
find.判断出作者认为四叶草带来的亲密感才是重要的。
4．答案与解析：C 主旨大意题。作者通过自己的经历，旨在表达并不只是四叶草能带来幸运，找到四叶草并和别人分享的那种亲密才是最重要的。故C选项“不只是运气”为短文的最佳标题。
B
【语篇解读】 文章属于说明文，介绍了一种长途飞行的蜻蜓Pantala
flavescens。这种蜻蜓冒险长途飞行的原因是它的繁殖需要湿润的气候。
5．答案与解析：D 推理判断题。根据第二段内容可知，领导这项研究的生物学家说基因就是证据。Pantala
flavescens蜻蜓在不同的洲有可能留有后代，才会有相似的基因。反过来，在不同的洲有共同的基因，证明了它们曾飞到过那儿，也就证明了这种蜻蜓是长途飞行者。
6．答案与解析：B 推理判断题。根据第三段中的These
dragonflies
have
adaptations
such
as
increased
surface
areas
on
their
wings
that
enable
them
to
use
the
wind
to
carry
them.可知这些蜻蜓适应性强，比如翅膀上表面积的增加，使它们能够利用风来飞行。故B项(运用风飞行的能力)正确。
7．答案与解析：A 细节理解题。根据第五段首句中的Wetness
is
a
must
for
Pantala
to
reproduce可知这种蜻蜓的繁殖必须要湿润的气候。
10．答案与解析：D 推理判断题。根据第五段内容可知，对于这种昆虫来说，这种危险的旅行是自杀式行为。虽然许多昆虫会死在途中，但这种物种依靠这种旅行生存下来。从后面一句While
many
will
die
on
the
route,
as
long
as
enough
make
it,
the
species
survives.可知，it指的是上文的危险旅行。
Ⅱ.七选五
【语篇解读】 文章属于说明文。介绍了一本美国畅销书《谁动了我的奶酪》。
1．答案与解析：D 前文提到“《谁动了我的奶酪》讲述了一个发生在老鼠和人之间的故事。”是该书的内容简介，D选项“该书的作者斯宾塞·约翰逊专为青少年写了这本书。”为作者的介绍，与前文对应。故选D项。
2．答案与解析：B 前文提到“这本书告诉我们，当我们面对生活中的变化时，比如新学校或新朋友，不要害怕”，B项“相反，利用这些变化来创造更好的生活。”与前文的内容衔接自然，“changes”与前文呼应。故选B项。
3．答案与解析：F 前文提到“在这里，奶酪意味着生活中重要的事情，比如搬到一个新的班级或进入大学。”指生活中出现了新变化，奶酪自然就不见了，后文又提到“必须找到更多的奶酪”。F项“但是他们发现奶酪不见了。”承上启下。故选F项。
4．答案与解析：G 上句提到“小矮人做不到这个”，G项“他们害怕变化，所以找不到奶酪。”解释前句小矮人找不到奶酪的原因。故选G项。
5．答案与解析：E 根据设空处前文可知，此处总结文章主旨，结合全文的启示，在生活中遇到变化时，我们需要快速融入环境。E项“为了得到更多的奶酪，快速地朝新的方向前进。”与文章的主旨相对应。故选E项。
