The
Internet
plays
a
big
part
in
human
life.
We
use
it
for
work
and
pleasure.
We
use
it
to
learn
a
new
language.
We
find
advice
on
it.
We
use
it
to
connect
with
our
family
and
friends.
We
use
it
to
stay
in
touch
with
events
we
care
about.
The
list
goes
on
and
on.
As
far
as
the
Internet
being
a
part
of
our
lives
—
well,
that_train_has_left_the_station.
There
is
no
possibility
of
going
back
to
an
Internet?free
life.
But
can
using
the
Internet
too
much
be
bad
for
our
health?
It
might
be,
say
researchers.
A
new
study
finds
that
heavy
Internet
use
may
be
connected
with
high
blood
pressure
(血压)
in
a
young
group:
teenagers.
The
study
results
show
that
teens
who
spend
at
least
14
hours
a
week
only
online
may
cause
high
blood
pressure,
which
makes
your
heart
and
blood
vessels
(血管)
work
too
hard.
Over
time,
this
extra
pressure
increases
your
risk
of
a
heart
attack.
High
blood
pressure
can
also
cause
other
diseases.
The
Henry
Ford
Hospital
in
Detroit,
Michigan
did
the
study.
335
young
people,
from
14
to
17
years
old,
took
part
in
it.
134
of
the
teens
are
described
as
“heavy
Internet
users”.
And
researchers
find
that
out
of
these
134
teens,
26
have
high
blood
pressure.
The
researchers
say
the
study
is
the
first
to
connect
heavy
web
use
with
high
blood
pressure.
The
lead
researcher
is
Andrea
Cassidy?Bushrow.
She
says,
“Using
the
Internet
is
part
of
our
daily
life,
but
it
should't
ruin
us.”
Ms.
Cassidy?Bushrow
adds
that
it
is
important
for
teens
to
stop
to
have
a
rest
regularly
from
their
computers
or
smartphones
and
do
some
kind
of
physical
activities.
She
also
suggests
that
parents
shouldn't
let
their
children
use
the
Internet
for
more
than
two
hours
a
day,
five
days
a
week.

has
changed
its

will
ruin
human
life
in

Alexa
is
a
form
of
artificial
intelligence,
or
AI
for
short.
Many
people
start
their
mornings
by
asking
Alexa
for
the
weather
forecast
or
the
latest
news.
A
device
(设备)
that
houses
Alexa
can
also
play
music
from
your
favourite
playlists,
keep
a
shopping
list,
order
takeout
food,
answer
questions,
send
messages
and
even
run
“smart”
home
controls.
Training
AI
systems
to
respond
to
problems
with
human?like
intelligence
and
learn
from
their
mistakes
can
take
months,
or
even
years.
Consider
Alexa
and
similar
software,
such
as
Apple's
Siri.
To
do
the
tasks
its
human
owners
ask,
these
systems
must
make
sense
of
and
then
respond
to
sentences
such
as,
“Alexa,
play
my
Ed
Sheeran
playlist”
or
“Siri,
what
is
the
capital
of
India？”
Computers
can't
understand
language
as
it
is
spoken
by
people.
So
AI
researchers
must
find
a
way
to
help
humans
communicate
with
computers.
The
technology
used
to
get
computers
to
“understand”
human
speech
or
text
is
known
as
natural
language
processing.
By
natural
language,
computer
scientists
refer
to
the
way
people
naturally
talk
or
write.
To
teach
an
AI
system
a
task
like
comprehending
(理解)
a
sentence
or
responding
to
a
person's
last
move
in
a
board
game,
scientists
need
to
feed
it
lots
of
examples.
AlphaGo
is
an
AI
system
designed
by
Google
that
has
beaten
a
human
champion,
Lee
Sedol,
at
the
strategy
(策略)
board
game
Go.
To
train
AlphaGo,
Google
had
to
show
it
30
million
Go
moves
that
people
had
made
while
playing
the
game.
Then
AlphaGo
used
what
it
learnt
to
analyse
those
plays
as
it
played
against
different
versions
(版本)
of
itself.
During
this
practice,
the
program
came
up
with
new
moves
—
ones
never
seen
in
games
between
people.
5．What
does
the
example
of
Alexa
show?
A．AI
may
replace
humans
one
day.
B．AI
is
playing
a
role
in
our
modern
life.
C．AI
has
been
widely
used
around
the
world.
D．AI
has
totally
changed
people's
bad
habits.
6．How
do
scientists
train
AI
systems?
A．By
testing
them
thousands
of
times.
B．By
teaching
them
almost
everything.
C．By
giving
them
quite
a
lot
of
tasks
to
do.
D．By
providing
them
with
large
amounts
of
data.
7．What
can
we
learn
about
AlphaGo?
A．It
has
become
very
skillful
and
intelligent.
B．It
is
the
most
convenient
AI
system.
C．It
avoids
making
any
mistake.
D．It
just
follows
human
orders.
Ⅲ.阅读七选五
Many
kids
and
teenagers
have
cellphones
in
their
hands.
However,
is
it
really
necessary
for
them
to
have
phones
at
school?
Here
are
the
pros
and
cons.
Pros
They
can
get
in
touch
when
necessary.
The
main
benefit
of
having
a
phone
is
that
your
children
can
get
in
touch
with
you
whenever
they
need
to.
__1__
They
can
call
the
emergency
services
if
necessary.
If
your
children
are
in
immediate
danger,
they
can
use
their
phones
to
call
not
only
you
but
the
emergency
services.
This
is
of
great
benefit
and
could
potentially
save
your
children's
lives.
__2__
As
long
as
your
children
remember
to
do
this,
their
phones
won't
cause
distraction
(分心)
in
class.
Giving
them
a
standard
instead
of
a
smartphone
will
also
reduce
the
risk
of
distraction.
Cons
The
latest
smartphones
can
almost
double
as
a
computer.
It
means
they
offer
far
more
of
a
distraction
to
kids
than
they
used
to.
__3__
All
these
characteristics
could
disturb
your
children's
concentration
(注意力)
if
they
play
with
them
in
class.
Cellphones
could
interrupt
lessons.
Many
children,
even
though
they
are
asked
to
do
so,
forget
to
turn
off
their
phones
during
lessons
and
their
phones
may
make
sounds.
__4__
Besides
the
distraction
problem,
cellphones
can
also
be
used
to
look
up
answers
on
the
Internet.
__5__
The
possibility
of
children
having
access
to
these
during
exams
could
be
too
attractive
for
them
not
to
take
advantage
of.
A．Cellphones
can
be
turned
off
or
put
on
mute.
B．Children
use
ordinary
phones
instead
of
smartphones.
C．This
allows
you
to
feel
they
are
safe
and
easy
to
reach.
D．Without
cellphones,
campus
life
would
be
less
colourful.
E．They
have
some
other
functions
—
a
calculator
and
the
ability
to
save
notes.
F．This
not
only
annoys
other
pupils,
but
also
prevents
them
from
learning
well.
G．Nowadays,
children
can
not
only
text
and
make
calls
with
their
phones,
but
also
play
games,
surf
the
Internet
and
listen
to
music.

A
If
you
use
social
media
to
chase
away
loneliness,
a
new
study
suggests
that
you're
going_against_the_grain.
We
may
have
heard
a
lot
about
the
benefits
of
interacting
with
others
online,
but
the
findings
of
a
study
conducted
by
scientists
from
the
University
of
Pittsburgh
School
of
Medicine
show
a
direct
relationship
between
social
media
usage
and
feelings
of
isolation
(孤独).
In
short,
the
more
time
you
spend
on
social
media,
the
lonelier
you
may
feel.
With
increasing
usage
of
a
large
number
of
apps
that
allow
for
endless
virtual
connectivity,
loneliness
seems
like
the
last
problem
frequent
social
media
users
would
face,
but
according
to
Brain
A.
Primack,
the
leader
of
the
study,
it
has
the
exact
opposite
effect.
“Mental
health
problems
and
social
isolation
are
widespread
among
young
adults
nowadays，”
Primack
said.
“We
are
naturally
social
creatures,
but
modern
life
tends
to
separate
us
instead
of
bringing
us
together.
While
it
may
seem
that
social
media
presents
opportunities
to
fill
the
social
void
(空白),
I
think
this
study
suggests
that
it
may
not
be
the
solution
people
were
hoping
for.”
Primack
and
his
team
examined
the
social
media
habits
of
1,787
U．S.
adults
aged
between
19
and
32
via
a
questionnaire
that
asked
about
the
frequency
and
the
time
they
spent
on
the
most
popular
social
media
platforms.
Eventually,
they
determined
that
young
adults
who
are
constantly
logging
in
social
media
are
lonelier
than
those
with
less
social
media
usage.
Frequent
exposure
to
unrealistic
descriptions
on
social
media
instead
of
face?to?face
social
interactions
may
give
people
the
impression
that
others
are
living
happier
and
have
more
sociable
lives,
and
this
may
make
users
feel
more
isolated
in
comparison.
1．What
does
the
underlined
phrase
“going
against
the
grain”
in
Paragraph
1
mean?
A．Doing
it
all
wrong.
B．On
the
way
to
success.
C．Taking
a
risk.
D．Making
a
difference.
2．How
did
Primack
and
his
team
conduct
the
study?
A．By
providing
explanations.
B．By
collecting
data
online.
C．By
doing
a
survey.
D．By
describing
their
own
experiences.
3．What
can
we
learn
from
the
study?
A．You
will
feel
happier
if
you
spend
more
time
online.
B．Online
interaction
is
not
the
solution
to
social
isolation.
C．Virtual
connectivity
is
the
best
way
to
fill
the
social
void.
D．Popular
social
media
platforms
can
bring
people
together.
B
You
can
often
choose
a
private
setting
when
you
browse
(浏览)
the
Internet.
But
be
forewarned:
It
may
not
afford
as
much
privacy
as
you
expect.
That's
the
finding
of
a
new
study.
Major
web
browsers
offer
a
private?browsing
option.
It's
sometimes
referred
to
as
“incognito
(隐姓埋名的)”.
This
option
lets
you
surf
the
Internet
and
saves
a
record
into
its
history
of
each
page
that
you
visit.
And
what
sites
you
visit
won't
affect
the
suggestions
your
browser
makes
the
next
time
you're
filling
out
an
online
form.
Many
people
believe
—
incorrectly
—
that
the
incognito
setting
protects
them
more
broadly.
Most
believe
it
even
after
reading
a
web
browser's
explanation
of
the
incognito
mode.
For
instance,
a
new
study
had
460
people
read
web
browsers'
descriptions
of
private
browsing.
Each
person
read
one
of
13
descriptions.
Then
the
participants
answered
questions
about
how
private
they
thought
their
browsing

be
while
using
this
tool.
The
volunteers
didn't
understand
the
incognito
mode.
This
was
true
no
matter
which
browser
explanation
they
had
read.
The
researchers
reported
their
findings
on
April
26
at
the
World
Wide
Web
Conference
2018
in
Lyon,
France.
More
than
half
of
the
volunteers
thought
that
if
they
logged
in
an
account
of
a
search
engine
through
a
private
window,
it
wouldn't
keep
a
record
of
their
search
history.
That's
not
true.
And
about
one
in
every
four
participants
thought
private
browsing
hid
their
device's
IP
address.
That's
also
wrong.
Blase

of
the
study's
authors.
He's
an
expert
in
computer

at
the
University
of
Chicago
in
Illinois.
“Companies
could
clear
up
this
confusion
by
giving
better
explanations
of
the
incognito
mode，”
his
team
said.
For
example,
the
browsers
should
avoid
vague
(模糊的)
expressions.
A
web
browser,
for
instance,
promises
users
that
“your
secrets
are
safe”.
Nope.
Another
encourages
users
to
“browse
like
no
one's
watching”.
In
fact,
someone
might
be.

A
【语篇解读】
这是一篇说明文。研究表明，人们在社交媒体上花的时间越多，可能会感到越孤独。
1．答案与解析：A'词义猜测题。由第一段的内容以及第二段的最后一句可知，如果你用社交媒体来排解孤独，一项新的研究表明这是在违反常理。简而言之，你在社交媒体上花的时间越多，可能会感到越孤独。所以通过语境可以判断出，第一段中加下划线的短语“going
against
the
grain”与“Doing
it
all
wrong”意思相近。故选A。
2．答案与解析：C'细节理解题。由第五段的第一句可知，Primack和他的团队通过问卷调查了1
787名19岁到32岁的美国成年人的社交媒体习惯，询问他们使用最受欢迎的社交媒体平台的频率和所花费的时间。所以Primack和他的团队是通过做一个调查进行这项研究的。故选C。
3．答案与解析：B'推理判断题。由第四段的最后一句可知，虽然社交媒体似乎提供了填补社交空白的机会，但研究表明，这可能并不是人们过去所希望的解决方案。由此可知，在线互动并不是解决孤独的办法。故选B。
B
【语篇解读】 这是一篇说明文。人们浏览互联网时，经常可以选择一个隐私设置，但这可能没有想象的那么保护人们的隐私。
4．答案与解析：B'推理判断题。由第四段中的“Then
the
participants
answered...
explanation
they
had
read”可知，研究人员进行这项研究的目的是调查用户对隐私浏览模式的了解程度。故选B。
5．答案与解析：C'推理判断题。由第二段中的“This
option
lets
you...
that
you
visit”以及第三段的第一句可知，此选项允许您浏览互联网，并记录您访问的每个页面。许多人错误地认为“匿名”模式能更广泛地保护他们的隐私。所以判断出人们认为“匿名”模式能够帮助隐藏浏览历史。故选C。
6．答案与解析：B'写作意图题。由最后一段中的“‘Companies
could
clear
up...
no
one's
watching’”可知，Blase
Ur的团队说，公司可以通过更好地解释匿名模式来澄清这种混淆。例如，浏览器应该避免模糊表达。由此判断出最后一段的目的就是为了提出建议。故选B。
Ⅲ.完形填空
【语篇解读】 本文主要介绍了中国传统文化中的春节这一节日。
1．答案与解析：A 句子的意思为“两件重要的事情帮助使这个假期与其它的有所不同。”故答案为A项。
2．答案与解析：D spend
the
holiday
with
sb.和某人一起度过假期。
3．答案与解析：B before意为“在……之前”，after“在……之后”，during“在……期间”，正确答案为B项，表示“春节前的几个星期”。
4．答案与解析：C town城镇，school学校，shop商店，restaurant饭店。为春节置办东西应该是在商店里，故正确答案为C项。
5．答案与解析：B 在报纸上要用介词in。
6．答案与解析：D 表“另外的、额外的、附加的”之意时，another置于数词之前，而more一般位于数词之后名词之前。
7．答案与解析：B 句子的意思为“无论你走到哪里，你都要意识到一年只有一次的春节又要来临了。”
Wherever表示“无论哪里”。Where哪里，Whatever无论什么，How怎样。
8．答案与解析：D 春节一年只有一次，因此正确答案为D项，once表示“一次”。
9．答案与解析：B 根据后文The
spirit
behind
the
present
matters
most可知，答案应该为B项，表示“送礼物”，而不是送钱，送愿望，也不是送贺卡。
10．答案与解析：A 因present是单数名词，故使用itself。
11．答案与解析：C return
to
the
hometown意为“回到家乡；返乡”。
12．答案与解析：C on表示特殊日子，on
New
Year's
Eve意为“在除夕”。
13．答案与解析：A would表过去经常做的事(过去常常)，might可能，could能、会，have
to不得不。句子的意思为“过去，在除夕，家里所有人都将待在家里一起包饺子。”故答案为A项。
14．答案与解析：A 选用Now，与其前的In
the
past形成对比。
15．答案与解析：D 根据其前的eating可知正确答案为D项，drinking意为“喝”。课时作业9 Unit

Ⅱ.阅读理解
A
Most
people
have
never
heard
of
Tim
Berners?Lee.
He
is
not
nearly
as
rich
or
famous
as
Marc
Andreessen,
who
is
the
founder
of
Netscape,
or
Bill
Gates,
whose
name
has
become
a
well?known
word.
Berners?Lee,
who
works
in
a
small
office
at
the
Massachusetts
Institute
of
Technology,
is
the
creator
of
the
World
Wide
Web.
The
creation
of
the
Web
is
so
important
that
some
people
compare
Berners?Lee
to
Johannes
Gutenberg,
who
invented
printing
by
movable
type
(活字)
in
the
fifteenth
century.
Berners?Lee
was
born
in
England
in
1955.
His
parents,
who
helped
design
the
world's
first
commercially
(商业地)
available
computer,
gave
him
a
great
love
of
mathematics
and
learning.
In
1980,
Berners?Lee
went
to
work
at
CERN,
a
physics
laboratory
in
Geneva,
Switzerland,
where
he
had
a
lot
of
material
to
learn
quickly.
He
had
a
poor
memory
for
facts
and
wanted
to
find
a
way
to
help
him
keep
track
of
things
he
couldn't
remember.
He
invented
a
software
program
that
allowed
him
to
create
a
document
that
had
links
to
other
documents.
He
continued
to
develop
his
idea
through
the
1980s.
He
wanted
to
find
a
way
to
connect
the
knowledge
and
creativity
of
people
all
over
the
world.
In
1991,
his
project
became
known
as
the
World
Wide
Web.
The
number
of
Internet
users
started
to
grow
quickly.
However,
Berners?Lee
was
not
completely
happy
with
the
way
the
Web
had
developed.
He
thought
it
had
become
a
passive
tool
for
so
many
people,
not
the
tool
for
creativity
that
he
had
imagined.
In
1999,
Berners?Lee
published
a
book
called
Weaving
the
Web,
in
which
he
answered
questions
he
was
often
asked,
“What
were
you
thinking
when
you
invented
the
Web？”“What
do
you
think
of
it
now？”
“Where
is
the
Web
going
to
take
us
in
the
future？”
1．What
can
we
learn
from
Paragraph
1?
A．Berners?Lee
has
never
heard
of
Netscape.
B．Berners?Lee
is
as
famous
as
Marc
Andreessen.
C．Berners?Lee
is
as
well?known
as
Bill
Gates.
D．We
know
little
about
Berners?Lee.
2．Who
invented
the
World
Wide
Web?
A．Johannes
Gutenberg.
B．Tim
Berners?Lee.
C．Bill
Gates.
D．Marc
Andreessen.
3．Which
of
the
following
is
TRUE?
A．In
1955,
Berners?Lee's
parents
gave
him
a
great
love
of
music.
B．In
1980,
Berners?Lee
wanted
to
find
a
way
to
connect
the
knowledge
and
creativity.
C．In
1991,
Berners?Lee
finished
the
World
Wide
Web.
D．In
1999,
Berners?Lee
made
a
play
called
Weaving
the
Web.
4．What
does
the
underlined
word
“published”
mean?
A．Printed
and
sent
out.
B．Bought
and
offered
to
others.
C．Invented
and
sold.
D．Wrote
and
exchanged.
B
I'll
never
forget
the
day
when
Mary
came
into
my
office
and
said,
“I
am
too
old
to
learn
how
to
use
a
computer.”
I
shook
my
head.
Here
was
a
woman
who
had
raised
6
children
and
who
had
made
great
progress
in
her
career
telling
me
that
she
was
too
old
to
learn
something
new.
I
told
her
that
I
always
believed
people
were
never
too
old
to
learn.
Mary
followed
my
advice
and
did
learn
how
to
use
the
computer.
Now,
she
is
retired
and
leading
a
very
active
life
volunteering
in
her
community,
using
her
computer
skills
and
helping
anyone
who
needs
help.
When
she
was
in
her
sixties,
one
day
she
called
me
and
said
she
had
played
the
piano
for
others
all
her
life,
and
she
was
going
to
make
a
CD
of
her
own.
My
mind
flashed
back
to
the
day
when
she
told
me
she
was
too
old
to
learn.
You
can
imagine
my
surprise
and
delight.
To
produce
the
CD,
she
had
a
lot
of
things
to
learn.
It
was
not
just
sitting
at
the
piano
and
playing.
She
had
to
research
the
songs,
learn
about
copyright
(版权),
and
learn
about
marketing.
It
was
pretty
amazing
for
someone
who
once
said
she
was
too
old
to
learn.
And
finally
she
made
it.
Now
she
has
her
own
CD.
Most
of
you
probably
have
heard
about
some
people
who
have
gone
back
to
university
in
their
seventies
and
have
also
graduated.
They
are
on
their
way
again
to
charging
themselves
with
a
new
skill
and
a
new
attitude
towards
life.
The
point
is
that
you
are
unable
to
learn
anything
at
any
age
if
you
believe
you
are
too
old.
On
the
contrary,
you
can
achieve
anything
at
any
age
if
you
believe
you
can.
5．When
Mary
said
she
was
too
old
to
learn,
how
did
the
author
react
to
it?
A．He
became
disappointed
with
her.
B．He
felt
sad
and
decided
to
help
her.
C．He
did
not
agree
with
her.
D．He
thought
what
she
had
said
was
true.
6．Why
did
Mary
call
the
author
one
day
in
her
sixties?
A．To
ask
him
for
some
help.
B．To
talk
about
her
new
CD.
C．To
ask
him
to
make
a
CD.
D．To
tell
him
about
her
plan.
7．What
was
the
author's
attitude
towards
Mary
making
a
CD?
A．He
thought
it
was
impossible.
B．He
thought
it
was
difficult.
C．He
thought
it
was
unnecessary.
D．He
thought
it
was
interesting.
8．What
does
the
text
mainly
tell
us?
A．We're
never
too
old
to
learn.
B．We
should
always
learn
new
skills.
C．Interest
is
the
best
teacher.
D．Some
people
succeed
for
a
reason.

One
possible
version：
Dear
Editor，
I'm
a
senior
high
school
student
named
Li
Hua.
Now
many
students
have
iPads
and
think
it's
a
fashion
to
use
them.
Using
an
iPad,
we
can
listen
to
music,
download
a
lot
of
learning
materials
and
read
e?books
on
the
screen.
Obviously,
it's
helpful
to
our
study,
especially
to
our
English
listening.
Some
students,
however,
bring
their
iPads
to
the
classroom
and
listen
to
music
without
earphones,
which
makes
the
teacher
and
other
students
greatly
annoyed.
Some
of
them
even
waste
precious
time
in
class
playing
video
games.
In
my
opinion,
as
students,
we
should
make
good
use
of
iPads
to
help
improve
our
study.
The
classroom
is
a
place
for
students
to
study,
and
therefore,
concentration
is
greatly
needed
for
us
to
learn
our
lessons.
Furthermore,
the
school
should
make
a
rule
to
guide
the
students
to
use
iPads
in
a
proper
way.
Yours
sincerely，
Li
Hua
