Ⅲ.阅读理解
A
Plants,
like
animals,
are
easy
to
be
infected
by
diseases
of
various
kinds.It
has
been
estimated
that
some
30,000
different
diseases
attack
our
economic
plants:
forty
are
known
to
attack
corn,
and
about
as
many
attack
wheat.The
results
of
unchecked
plant
disease
are
all
too
obvious
in
countries
which
have
only
a
limited
number
of
food
supplies.The
problem
will
soon
be
more
widespread
as
the
population
of
the
world
increases
at
its
frightening
rate.Even
in
countries
which
are
now
amply
fed
by
their
agricultural
products,
there
could
soon
be
serious
food
shortages.It
is
easy
to
imagine
the
outcome
of
some
disastrous
attack
on
one
of
the
major
crops;
the
resulting
famines
could
kill
millions
of
people,
and
the
resulting
hardship
on
other
millions
could
cause
political
disturbance
disastrous
to
the
order
of
the
world.
Some
plants
are
born
with
the
ability
to
resist
a
great
many
diseases,
while
others
are
fairly
easy
to
be
infected.The
tolerance
(耐受性)
of
a
particular
plant
changes
as
the
growing
conditions
change.A
blight
(枯萎病)
may
be
but
a
local
infection
which
can
be
easily
controlled;
on
the
other
hand,
it
can
attack
particular
plants
in
a
whole
region
or
nation.An
example
is
the
blight
which
killed
actually
every
chestnut
tree
in
North
American.Another
is
the
famous
potato
blight
in
Ireland
in
the
last
century.As
a
result
of
that,
it
was
estimated
that
one
million
people
died
of
starvation
as
potatoes
were
the
main
food
for
Irish
people.
Plant
pathologists
have
made
remarkable
progress
in
identifying
the
pathogens
(病原体)
of
the
various
diseases.Bacteria
may
invade
a
plant
by
way
of
insects
carrying
the
pathogen.A
plant
can
also
be
inoculated
by
man.Frequently
a
primary
infection
will
weaken
the
plant
so
that
a
secondary
infection
may
result
from
its
lack
of
tolerance.The
symptoms
shown
may
cause
an
error
in
diagnosis,
so
that
the
treatment
may
be
directed
toward
bacteria
which
could
be
the
result
of
a
susceptibility
caused
by
a
primary
virus
infection.
1.How
many
diseases
are
known
to
attack
wheat
A．Around
30,000.
B．40.
C．Around
29,960.
D．Around
40.
解析：选B 细节理解题。由文章第一段第二句可知，危害谷类作物的疾病和危害小麦的数目一样多。故选B项。
2．Which
of
the
following
statements
in
NOT
true
A．A
major
crop
disease,
if
not
checked,
would
result
in
many
deaths
in
a
country.
B．A
major
crop
disease,
if
not
checked,
would
result
in
food
shortages
in
rich
countries.
C．A
major
crop
disease,
if
not
checked,
would
result
in
an
increase
of
world
population.
D．A
major
crop
disease,
if
not
checked,
would
result
in
political
unrest.
解析：选C 细节理解题。根据第一段的叙述，A、B、D都可找到原文依据，C项没有列出。另外，根据常识，农作物疾病怎么能造成人口增加呢？我们也可看出C项为答案。
3．What
is
the
main
idea
of
the
second
paragraph
A．Some
plants
can
resist
a
great
many
diseases,
while
others
have
low
immunity
to
them.
B．The
growing
conditions
have
little
impact
on
the
tolerance
of
a
particular
plant.
C．In
most
cases,
blight
develops
in
North
America.
D．A
blight
once
killed
virtually
every
chestnut
tree
in
North
America.
解析：选A 主旨大意题。第二段中第一句话为主题句，其他为细节，用来详细解说该主题。
4．Which
of
the
following
statements
is
NOT
true
A．Symptoms
are
always
misleading.
B．Some
plant
diseases
may
be
caused
by
pathogens.
C．Some
plant
diseases
may
be
indirectly
caused
by
men.
D．A
primary
infection
may
lead
to
a
secondary
infection.
解析：选B 细节理解题。仔细阅读最后一段可知，该段第一句说科学家“在研究病原菌方面有很大进展”，但没有说明是否病原菌是疾病的根源。故选B项。
B
Pilates,
yoga
and
the
running
machine
get
all
the
attention
when
it
comes
to
popular
ways
to
stay
healthy.
There
is,
however,
a
more
humble
exercise
that
might
not
be
so
attractive,
but
has
all
the
benefits
—
walking.
Certified
fitness
professional
Jolynn
Jaekel
explains,
“What
I
love
about
walking
is
that
anyone
can
do
it
at
any
age
and
any
fitness
level.
Plus,
it
is
good
for
your
heart,
your
head
and
your
wallet.”
A
recent
report
details
the
health
benefits
of
walking.
The
report
found
that
walking
regularly
to
fulfill
the
150
minutes
of
moderate
physical
exercise
every
week,
recommended
by
the
UK's
chief
medical
officer,
could
save
37,000
lives
each
year.
Scientists
at
the
Lawrence
Berkeley
National
Laboratory
in
California
found
that
quick
walking
reduces
the
risk
of
heart
disease
more
effectively
than
running.
They
observed
participants
aged
between
18
and
80
over
a
six year
period
and
found
that
walking
reduced
the
risk
of
heart
disease
by
9.3%,
while
running
reduced
it
by
4.5%.
And
there
is
even
more
good
news:
30
minutes
of
quick
walking
over
five
days
could
help
you
sleep
easily,
according
to
research
by
Oregon
State
University.
The
study
by
the
university
showed
that
walking
helped
participants
sleep
better
and
feel
more
alert
during
the
day.
The
sooner
you
get
started,
the
sooner
you'll
notice
the
differences
in
your
mind
and
body.
So,
go
out
for
your
30 minute
walk
in
a
nearby
park
or
green
space.
5．The
underlined
word
“humble”
in
the
first
paragraph
probably
means
“________”．
A．plain
B．relaxing
C．popular
D．active
解析：选A 词义猜测题。根据第一段可知，当提到保持健康的方式时首先可以想到普拉提、瑜伽和跑步机。然而，有一种不太引人注目的简单运动却让人受益匪浅，那就是步行。由此可推知，画线词和“plain”意义相近。故A项正确。
6．What
does
Jolynn
Jaekel
think
of
walking
A．It's
loved
by
people
of
all
ages.
B．It's
much
healthier
than
running.
C．It's
a
money saving
physical
exercise.
D．It's
becoming
more
and
more
popular.
解析：选C 细节理解题。根据第二段中的“What
I
love
about
walking
...
your
head
and
your
wallet.”可知，步行对人的心脏和大脑都有好处并且可以省钱。故C项正确。
7．What
did
scientists
at
the
Lawrence
Berkeley
National
Laboratory
find
A．Walking
helps
people
with
sleep
problems.
B．Walking
contributes
to
curing
heart
disease.
C．Walking
150
minutes
per
week
can
save
lives.
D．Walking
is
better
than
running
in
some
cases.
解析：选D 细节理解题。根据第三段第三句中的“found
that
quick
walking
reduces
the
risk
of
heart
disease
more
effectively
than
running”以及下文将步行和跑步从几个方面进行的对比来看，前者优于后者。故D项正确。
8．In
which
section
of
a
newspaper
can
we
read
this
text
A．Comment.
B．Lifestyle.
C．Education.
D．Science.
解析：选B 文章出处题。纵观全文可知，本文主要介绍了健康生活方式中的最简单有效的方式——步行。由此可推知，可从报纸上介绍生活方式的版块读到该文章。故B项正确。Unit

This
is
the
most
exciting
kayaking
expedition
(皮划艇探险)
possible
for
beginner
kayakers.
You
can
expect
to
experience
a
whole
range
of
different
conditions
and
scenery.
This
expedition
is
a
total
of
8.27
km
in
distance
and
it
actually
enters
the
streams
in
the
North
of
Ubin
and
exits
in
the
South.
Three
and
a
half
kilometers
of
pure
mangroves
(红树林),
makes
this
the
longest
pure
mangrove
kayaking
expedition
in
Singapore.
The
distance
spent
inside
the
mangrove
gives
you
the
maximum
opportunity
to
witness
wildlife
within
the
mangrove
eco system.
Come
to
experience
the
challenge
of
operating
your
kayak
through
the
labyrinth
(迷宫)
of
waterways
and
be
amazed
at
the
calm
and
quiet
beauty
of
the
wetlands.
This
last
corner
of
natural
wilderness
in
Singapore
is
so
inaccessible,
that
very,
very
few
have
ever
experienced
it
—
which
makes
this
a

Ⅴ.阅读理解
A
Botany,
the
study
of
plants,
occupies
a
special
position
in
the
history
of
human
knowledge.For
many
thousands
of
years
it
was
a
field
about
which
humans
had
a
great
deal
to
learn.It
is
impossible
to
know
today
just
what
our
Stone
Age
ancestors
knew
about
plants,
but
from
what
we
can
observe
of
pre industrial
societies
that
still
exist,
a
detailed
learning
of
plants
and
their
properties
must
be
extremely
ancient.This
is
logical.
Plants
are
the
basis
of
the
food
pyramid
for
all
living
things,
even
for
other
plants.They
have
always
been
important
to
the
benefit
of
peoples,
not
only
for
food,
but
also
for
clothing,
weapons,
tools,
dyes,
medicines,
shelter,
and
a
great
many
other
purposes.Tribes
living
today
in
the
jungles
of
the
Amazon
recognize
hundreds
of
plants
and
know
many
properties
of
each.To
them
botany,
as
such,
has
no
name
and
is
probably
not
even
recognized
as
a
special
branch
of
“knowledge”
at
all.
Unfortunately,
the
more
industrialized
we
become
the
farther
away
we
move
from
direct
contact
with
plants,
and
the
less
definite
our
knowledge,
and
few
people
will
fail
to
recognize
a
rose,
and
apple,
or
an
orchid.
When
our
ancestors,
living
in
the
Middle
East
about
10,000
years
ago,
discovered
that
certain
grasses
could
be
harvested
and
their
seeds
planted
for
richer
harvests
the
next
season,
the
first
great
step
in
a
new
association
(联系)
of
plants
and
humans
was
taken.Grains
were
discovered
and
from
them
flowed
the
wonder
of
agriculture:
cultivated
crops.From
then
on,
humans
would
increasingly
take
their
living
from
the
controlled
production
of
a
few
plants,
rather
than
getting
a
little
here
and
a
little
there
from
many
varieties
that
grew
wild
—
and
the
accumulated
(积累)
knowledge
of
tens
of
thousands
of
years
of
experience
and
close
contact
with
plants
in
the
wild
would
begin
to
fade
away.
1．Which
of
the
following
statements
is
TRUE
A．Early
humans
knew
nothing
about
plants.
B．Early
humans
probably
had
extensive
knowledge
of
plants.
C．Early
humans
had
little
knowledge
of
plants.
D．Early
humans
did
not
enjoy
the
study
of
botany.
解析：选B 细节理解题。由第一段第三句的前半部分可知B项正确。
2．In
Paragraph
1
the
underlined
word
“properties”
refers
to________.
A．the
belongings
of
early
humans
B．the
wealth
of
ancient
people
C．the
characteristics
or
qualities
of
plants
D．Both
B
and
C
解析：选C 词义猜测题。全文出现property的地方有两处，除了第一段之外，在第二段倒数第二句话还能找到。观察其搭配，可发现这个词两处都与plant联用，可猜出其意思与人类无关，故选C项。
3．Tribes
living
today
in
the
jungle
of
the
Amazon________.
A．don't
know
anything
about
plants
B．recognize
botany
as
a
branch
of
science
C．first
give
the
name
of
botany
D．are
experts
of
plants
解析：选D 细节理解题。从第二段看出，亚马孙丛林中的部落人能认识数百种植物，并熟悉它们的属性。他们不知道什么叫“植物学”，这些知识只是想当然的事，甚至不纳入“知识”范畴。故选D项。
4．According
to
the
passage,
what
was
the
first
great
step
toward
the
practice
of
agriculture
A．The
invention
of
agricultural
implements
and
machinery.
B．The
development
of
a
system
of
names
for
plants.
C．The
discovery
of
grasses
that
could
be
harvested
and
replanted.
D．The
changing
diets
of
early
humans.
解析：选C 细节理解题。从最后一段第一句中可以得出答案。
B
The
Japanese
like
parties.From
ancient
times,
a
party
becomes
enlivened
(活泼)
when
someone
starts
singing
and
others
keep
applauding.Having
such
a
custom,
the
Japanese
can
easily
sing
in
front
of
others
without
feeling
embarrassed.This
seems
to
be
one
of
the
reasons
that
karaoke
has
been
largely
accepted
in
Japanese
society.
It
is
now
widely
recognized
that
the
use
of
karaoke
started
at
a
snack
bar
in
Kobe
City,
one
of
the
three
biggest
cities
in
Japan.It
is
said
that
when
a
guitarist
could
not
come
to
perform
at
the
bar
due
to
illness,
the
owner
of
the
bar
prepared
tapes
of
accompaniment
recordings,
and
people
enjoyed
singing
to
the
tapes.
It
was
at
that
time
that
karaoke
appeared.Holding
a
microphone
and
singing
a
song
to
the
accompaniment
of
an
“orchestra
(管弦乐队)”，
you
can
feel
like
a
professional
singer.For
soldiers
living
in
a
stressful
society,
there
is
no
other
entertainment
activity
that
can
make
them
feel
so
refreshed.
It
is
a
typical
way
to
relax
for
Japanese
businessmen.They
use
it
to
take
away
their
stress
after
work.However,
there
is
an
obstacle
to
this:
since
most
Japanese
houses
are
still
made
of
wood,
it
would
be
very
annoying
to
the
neighbors
to
sing
into
a
microphone
at
night.Seizing
upon
the
opportunity,
businessmen
created
the
karaoke
box,
a
roadside
facility
containing
karaoke
equipment.Karaoke
boxes
are
soundproofed
rooms,
closed
with
a
door,
placed
on
roadsides
where
people
can
sing.The
first
“Karaoke
box”
was
placed
in
a
rice
camp
in
the
countryside
in
1984.It
was
built
from
a
converted
freight
car
(改装的货运车)．Now,
the
karaoke
boom
has
even
spread
abroad
and
it
has
also
been
attracting
the
attention
of
the
countries
trying
to
improve
their
literacy
rate
(识字率)
as
a
good
educational
tool.
5．According
to
the
text,
we
can
learn
that
karaoke
________.
A．originated
from
the
biggest
city
of
Japan
B．originated
in
the
form
of
singing
to
tapes
C．can
help
you
achieve
the
level
of
professional
singers
D．first
appeared
in
the
army
to
relieve
stress
for
soldiers
解析：选B 细节理解题。根据第二段可知卡拉OK起源于日本三个大城市之一，Kobe的一间小零食店，这家小店因为吉他手生病不能演奏，店主就录制了吉他手的乐曲，歌手唱歌时播放录制的音乐，因此可知A项错误，B项正确。根据第三段“feel
like
a
professional
singer”可知卡拉OK让你的歌声听起来像专业歌手的歌声，并不能让你真正达到专业歌手水平，故排除C。文章第三段提到卡拉OK是士兵缓解压力的不二方式，但卡拉OK并非诞生于军营，故排除D。
6．The
underlined
word
“soundproofed”
in
Paragraph
4
most
probably
means
“________”．
A．recording
sounds
repeatedly
B．receiving
sound
signals
C．making
sound
more
clear
D．stopping
sound
from
being
heard
outside
解析：选D 词义猜测题。根据画线单词前后语境可知由于日本的房子大都是木房子，隔音效果差，因此唱歌时会影响周围居民的生活，商人抓住这一商机发明了包厢，这是一种关闭门窗，置于路边的隔音效果较好的房子。因此根据语境可以推断soundproofed意思是“隔音的”，故D项符合题意。
7．What
can
be
inferred
from
the
text
A．Karaoke
was
started
in
a
bar
during
a
party.
B．A
guitarist
was
the
originator
who
brought
the
karaoke
into
being.
C．Karaoke
was
very
common
as
a
form
of
entertainment
at
home
when
it
was
born.
D．Karaoke
is
used
as
a
way
of
education
in
some
countries.
解析：选D 推理判断题。根据文章最后一段最后一句中的“attracting
the
attention
of
the
countries
trying
to
improve
their
literacy
rate
(识字率)
as
a
good
educational
tool”可知D项正确。卡拉OK起源于一家小零食店，由于吉他手生病，店主想出了用录制音乐伴奏的法子，故推断A和B均错误。根据最后一段可知由于噪音大影响邻居，因此卡拉OK的发展受到限制，故推断C项错误。
8．What
is
the
text
mainly
about
A．What
karaoke
boxes
are
like.
B．How
karaoke
boxes
were
created.
C．The
origins
and
development
of
karaoke.
D．Karaoke
becomes
a
popular
form
of
entertainment.
解析：选C 主旨大意题。本文介绍了卡拉OK的起源和发展，故选C。
