Diets
have
changed
in
China—and
so
has
its
top
crop.Since
2011,the
country
1.
(grow)
more
corn
than
rice.Corn
production
has
jumped
nearly
125
percent
over
2.past
25
years,while
rice
has
increased
only
7
percent.
A
taste
for
meat
is
3.(actual)
behind
the
change—an
important
part
of
its
corn
is
used
to
feed
chickens,pigs,and
cattle.Another
reason
for
corn’s
rise—the
government
encourages
farmers
to
grow
corn
instead
of
rice
4.
(improve)
water
quality.Corn
uses
less
water
5.
rice
and
creates
less
fertilizer(化肥)
run-off.This
switch
has
decreased
6.
(pollute)
in
the
country’s
major
lakes
and
reservoirs
and
made
drinking
water
safer
for
people.
According
to
the
World
Bank,China
accounts
for
about
30
percent
of
total
7.
(globe)
fertilizer
consumption.The
Chinese
Ministry
of
Agriculture
finds
that
between
2005—when
the
government
8.

a
soil-testing
program
9.
gives
specific
fertilizer
recommendations
to
farmers—and
2011,fertilizer
use
dropped
by
7.7
million
tons.That
prevented
the
emission(排放)
of
51.8
million
tons
of
carbon
dioxide.China’s

答案与解析
【语篇解读】本文是一篇说明文。文中讲述了中国为保护环境在农作物种植上做了一些变化并得到了世界上知名人士的认可。
Ⅵ.七选五
Most
of
us
in
China
are
used
to
paying
for
everything
with
our
phones. 1
At
least,this
was
the
case
for
Lim
Swee
Say
from
Singapore,who
found
his
first
experience
with
Chinese
payment
methods
quite
impressive.Lim
was
waiting
in
line
to
buy
nuts
at
a
street
stall
(货摊)
in
Shanghai
and
saw
other
customers
show
their
phones
and
take
the
nuts
without
giving
cash. 2
It
seems
that
Singapore
falls
behind
in
mobile
payments.Some
Chinese
tourists
find
it
inconvenient
when
they
have
to
use
cash
in
Singapore.?
3
According
to
Xinhua
News
Agency,many
countries
now
accept
mobile
payment
services
for
Chinese
tourists,with
WeChat
Pay
covered
in
13
overseas
countries
and
regions
and
Alipay
over
200.It’s
now
common
to
see
the
familiar
green
or
blue
logos
in
tourist
destinations
around
the
world,from
a
tiny
shop
in
the
Scottish
Highlands
to
a
huge
department
store
in
New
York.?
Mobile
payments
are
now
a
normal
part
of
life
in
China,and
the
trend
is
sweeping
other
nations.According
to
Forrester
Research,in
America,mobile
payments
rose
by
37
per
cent
in
2016. 4 This
may
be
partly
because
western
mobile
payment
services
require
businesses
to
install
expensive
equipment
before
customers
can
use
them. 5 ?
A.He
was
trying
to
figure
out
how
they
got
paid.
B.Foreign
tourists
don’t
like
to
pay
with
their
mobile
phones.
C.But
in
China,all
it
takes
is
a
QR
code
(二维码)
and
a
phone.
D.Soon
after,he
realised
that
the
customers
were
using
WeChat
Pay.
E.Still,Chinese
mobile
payments
were
nearly
50
times
greater
than
those
in
the
US.
F.But
for
foreign
visitors
who
aren’t
familiar
with
this
method,it
may
seem
strange.
G.The
popularity
of
Chinese
mobile
payments
has
pushed
some
foreign
companies
to
accept
them.Unit

Ⅳ.阅读理解
Don’t
talk
to
me;I’m
busy
with
my
iPhone.
Riding
the
London
underground,a
person
from
China
will
notice
one
major
difference:in
London,people
do
not
look
at
each
other.In
fact,eye
contact
is
avoided
at
all
times.That’s
not
rudeness—people
are
just
too
busy
to
bother
looking.
Busy
doing
what,you
ask?Well,they’re
certainly
not
using
the
time
for
a
moment
of
quiet
reflection,nor
are
they
reading
a
book.New
technology
has
replaced
quiet
habits.Today
the
only
acceptable
form
of
books
on
the
London
underground
is
an
e-book.
Apple
must
earn
a
fortune
from
London
commuters(乘车上下班的人).Since
the
launch
of
the
iPhone
in
2007,over
40,000—yes,that’s
40,000—“apps”
(programs
downloaded
for
the
iPhone)
have
been
muters
love
them
because
they
are
the
perfect
time-killers.One
“app”,called
iShoot,is
a
game
that
features
tanks.Another
one,Tube
Exits,tells
passengers
where
to
sit
on
the
train
to
be
closest
to
the
exit
of
their
destination.ISteam
clouds
the
iPhone
screen
when
you
breathe
into
the
microphone.You
can
then
write
in
the
“
steam”
on
your
phone
screen.
For
those
without
an
iPhone,another
Apple
product,the
iPod,may
be
another
choice.It’s
not
just
teenagers
who
“plug
in”
to
their
music—iPods
are
a
popular
way
to
pass
the
time
for
all
ages.
And
if
games,e-books
and
music
aren’t
enough
to
keep
you
occupied.Then
perhaps
you
would
prefer
a
film.The
development
of
palm
DVD
technology
means
many
commuters
watch
their
favourite
TV
show
or
film
on
the
way
to
work.With
all
these
entertainments,it’s
amazing
that
people
still
remember
to
get
off
the
train.

A
主题语境:信息时代
In
many
aspects,nowadays
business
environment
has
changed
greatly
since
the
late
1980s.The
end
of
the
cold
war
completely
altered
the
very
nature
of
the
world’s
politics
and
economics.In
just
a
few
short
years,globalization
has
started
a
variety
of
trends
with
profound
consequences:the
opening
of
markets,true
global
competition,widespread
deregulation
(解除政府对……的控制)
of
industry,and
an
abundance
of
accessible
capital.We
have
experienced
both
the
benefits
and
risks
of
a
truly
global
economy,with
both
wall
street
and
main
street
(平民百姓)
feeling
the
pains
of
economic
disorder
half
a
world
away.
At
the
same
time,we
have
fully
entered
the
information
age,starting
breakthroughs
in
information
technology,which
have
irreversibly
altered
the
ability
to
conduct
business
unconstrained
by
the
traditional
limitations
of
time
or
space.Today,it’s
almost
impossible
to
imagine
a
world
without
intranets(内联网),e-mail,and
portable
computers.With
amazing
speed,the
Internet
is
profoundly
changing
the
way
we
work,shop,do
business,and
communicate.
As
a
consequence,we
have
truly
entered
the
post-industrial
economy.We
are
rapidly
shifting
from
an
economy
based
on
manufacturing
and
commodities
to
one
that
places
the
greatest
value
on
information,services,support,and
distribution.That
shift,in
turn,attaches
great
importance
to
“knowledge
workers”,a
new
class
of
wealthy,educated,and
mobile
people
who
view
themselves
as
free
agents
in
a
seller’s
market.
Beyond
the
field
of
information
technology,the
increasing
pace
of
technological
change
in
virtually
every
industry
has
created
entirely
new
business,wiped
out
others,and
produced
a
great
demand
for
continuous
innovation
(创新).New
product,process,and
distribution
technologies
provide
powerful
levers
for
creating
competitive
value.More
companies
are
learning
the
importance
of
destructive
technologies——innovations
that
hold
the
potential
to
make
a
product
line,or
even
an
entire
business
segment,virtually
outdated.
Another
major
trend
has
been
the
consumer
and
business
markets.There’s
a
growing
appreciation
that
superficially
similar
groups
of
customers
may
have
very
different
preferences
in
terms
of
what
they
want
to
buy
and
how
they
want
to
buy
it.Now,new
technology
makes
it
easier,faster,and
cheaper
to
identify
and
serve
targeted
micro-markets
in
ways
that
were
physically
impossible
or
prohibitively
expensive
in
the
past.Moreover,the
trend
feeds
on
itself—a
business’s
ability
to
serve
sub-markets
fuels
customers’
appetites
for
more
and
more
specialized
offerings.

主题语境:人工智能
Computers
have
become
so
smart
during
the
past
20
years
that
people
don’t
think
twice
about
chatting
with
digital
assistants
like
Alexa
and
Siri.But
that
required
hard
work
from
computer
scientists
like
Yoshua
Bengio,Geoffrey
Hinton,and
Yann
LeCun.They
tapped
into
their
own
brainpower
to
make
it
possible
for
machines
to
learn
like
humans,a
breakthrough
now
commonly
known
as
“artificial
intelligence”,or
AI.
Their
insights
and
persistence
were
rewarded
with
the
Turing
Award,an
honour
that
has
become
known
as
technology
industry’s
version
of
the
Nobel
Prize.The
award
marks
the
latest
recognition
of
the
instrumental
role
that
artificial
intelligence
will
likely
play
in
redefining
the
relationship
between
humanity
and
technology
in
the
decades
ahead.
Over
the
past
30
years,Mr.Bengio,Mr.Hinton,and
Mr.LeCun
have
mostly
worked
separately
on
technology
known
as
neural
(神经的)
networks.These
are
the
electronic
engines
that
power
tasks
such
as
facial
and
speech
recognition,areas
where
computers
have
made
huge
improvements
over
the
past
decade.Such
neural
networks
also
are
a
key
part
of
robotic
systems
that
are
automating
a
wide
range
of
other
human
activities,including
driving.
Their
belief
in
the
power
of
neural
networks
was
once
looked
down
upon.“For
a
long
time,people
thought
what
we
were
doing
was
nonsense,”
Mr.Hinton
said
in
an
interview
with
The
Associated
Press.“They
thought
we
were
very
misguided
and
what
we
were
doing
was
a
very
surprising
thing
for
apparently
intelligent
people
to
waste
their
time
on.My
message
to
young
researchers
is,don’t
be
put
off
if
everyone
tells
you
what
you
are
doing
is
silly.”
While
the
AI
revolution
is
raising
hopes
that
computers
will
make
most
people’s
lives
more
convenient
and
enjoyable,it’s
also
arousing
fears
that
humanity
eventually
will
be
living
at
the
mercy
of
machines.Mr.Bengio,Mr.Hinton,and
Mr.LeCun
are
also
concerned
that
AI
technology
might
be
developed
into
weapon
systems
that
wipe
out
humanity.
But
they
are
far
more
optimistic
about
the
other
prospects
of
AI—empowering
computers
to
deliver
more
accurate
warnings
about
floods
and
earthquakes,or
detecting
health
risks,such
as
cancer
and
heart
attacks,far
earlier
than
human
doctors.
