Ⅰ.七选五
Without
us
even
realizing
it,
smartphones
have
taken
over
our
lives.Most
of
us
can't
go
much
longer
than
10
minutes
before
we
check
our
phones.
__1__.There
was
a
time,
however,
before
smartphones
even
existed.
1．Watching
Gigs
Without
Being
Compelled
to
Film
Before
smartphones
took
over
our
lives,
we
actually
watched
concerts
with
our
eyes.
__2__.
2．Trying
and
Failing
to
Date
Other
People
Dating
without
the
help
of
the
smartphone
was
a
very
real
and
painful
situation.The
sheer
terror
of
actually
having
to
approach
a
real
person,
in
real
life,
is
utterly
unthinkable
and
we
can
all
let
out
a
sigh
of
relief
for
the
invention
of
dating
apps.
3．__3__
Before
access
to
online
maps
was
a
regular
part
of
our
world,
we
faced
the
very
real
danger
of
getting
lost
and
having
no
idea
how
to
get
out.The
fact
that
more
of
us
didn't
vanish
off
the
face
of
the
earth
is
frankly
a
miracle.
4．Making
Proper
Mixtapes,
on
Real
Tapes
If
we
wanted
to
express
how
we
felt
to
others,
we
had
to
do
the
following.We
went
to
all
of
the
effort
of
finding
real
CDs
and
somehow,
recording
all
of
the
best
bits
onto
another
blank
disc.That
was
love.Now,
we're
just
all
a
bit
lazy.
5．Learning
Phone
Numbers
off
by
Heart
If
we
wanted
to
call
our
beloved
out
of
the
blue,
we
had
to
commit
their
digits
to
memory.The
fact
that
we
managed
to
memorize
all
of
our
essential
numbers
is
an
incredible
feat
and
should
be
celebrated.
6．Ignoring
Your
Embarrassing
Questions
If
you
wanted
to
find
out
more
about
a
weird
spot
on
your
back,
or
look
into
a
trashy
celebrity's
early
life,
you
normally
just
let
it
go.
__4__
and
unless
you
really
wanted
the
truth,
you
normally
forgot
all
about
it.
7．Twiddling
Your
Fingers
on
the
Toilet
__5__.
With
nothing
to
look
at
but
white
walls
and
the
ground,
most
of
us
took
up
finger
twiddling
as
a
bathroom
pastime.
A．Finding
out
information
required
a
lot
of
effort
B．Getting
Genuinely
Lost
C．Having
Unpleasant
Experiences
D．A
trip
to
the
toilet
used
to
be
a
blank
spot
in
the
day
E．Toilet
was
always
a
good
place
to
make
a
serious
thought
about
life
F．If
we
find
ourselves
without
the
device,
we
can
feel
more
than
a
little
lost
G．But
now,
seeing
anything
that
isn't
framed
by
a
mini
screen
just
feels
wrong
手机已经占领了我们的生活，手机控无处不在。文章帮我们回忆了手机发明前的生活状况。
1．F 解析：上文从正面介绍了人们对手机的依赖和痴迷程度：许多人甚至坚持不了10分钟，就一定要去看一下手机。所以此处应该是从反面阐述人们对手机的依赖。故F项“如果我们发现手机不在身边，就会有一种深深的失落感”符合逻辑。
2．G 解析：本段阐述的是在手机占领我们的生活前后视觉的变化。空前句子中的watched和G项中的seeing相呼应。
3．B 解析：本段的关键词为getting
lost，只有B项“真的会迷路”与之匹配。
4．A 解析：本段的小标题意为“无视你脑中的囧问题”。这些“问题”就是空格前所说的问题，A项“Finding
out
information
required
a
lot
of
effort”是对这些问题的进一步描述。故选A项。
5．D 解析：本段的小标题Twiddling
Your
Fingers
on
the
Toilet意为“在马桶上无聊地玩手指”。空后表达的意思是：除了白色的墙壁和地板没有什么可看的，所以许多人就只好玩手指，当作如厕时间的消遣。这与D项“过去，上厕所的时间通常是一天中空白的时间”一致。故选D项。
Ⅱ.翻译下列句子，注意黑体部分要用到本单元的单词、短语或句型，然后将其合并成一篇短文
1．李平决定开始努力学习英语。
Li_Ping_decided_to_set_out_to_study_English_hard.
2．首先，他着手研究与电话有关的词语。
To_begin_with,_he_set_about_doing_a_research_on_the_expressions_associated_with_the_phone.
3．他想弄清楚怎样区分“hang
on”和“hang
up”。
He_wanted_to_make_clear_how_to_distinguish_“hang_on”_from_“hang_up”．
4．昨天他打电话给老师，却打不通。
He_called_up_his_teacher_yesterday_but_couldn't_get_through.
5．他的电话偶尔出毛病。
His_phone_was_out_of_order_now_and_then.
6．所以他查词典弄清楚了它们的区别。
So_he_looked_them_up_in_the_dictionary_to_tell_the_difference_between_them.
7．通过这件事他得出一个结论：如果抓住每个学习英语的机会，他一定会学好它的。
He_drew_a_conclusion_from_this_thing_that_if_he_seized_every_opportunity_to_learn_English,_he_was_sure_to_learn_it_well.
请将以上句子连成一篇语言流畅、逻辑严密的短文。
Li_Ping_decided_to_set_out_to_study_English_hard._To_begin_with,_he_set_about_doing_a_research_on_the_expressions_associated_with_the_phone._He_wanted_to_make_clear_how_to_distinguish_“hang_on”_from_“hang_up”，_so_he_called_up_his_teacher_yesterday.However,_he_couldn't_get_through_because_his_phone_was_out_of_order_now_and_then._So_he_looked_them_up_in_the_dictionary_to_tell_the_difference_between_them._He_drew_a_conclusion_from_this_thing_that_if_he_seized_every_opportunity_to_learn_English,_he_was_sure_to_learn_it_well.Unit

Ⅰ.阅读理解
Maybe
you've
just
invented
something
better
than
the
iPhone
or
a
solar?powered
car.You
don't
want
anyone
to
steal
your
design.What
should
you
do?
Patent
(申请专利)
it！Patents
are
the
best
way
to
get
credit
for
your
work
and
help
others
continue
advancing
in
that
field.Here's
what
you
need
to
know.
A
patent
gives
you
the
right
to
an
invention.The
patent
protects
its
owner，which
means
the
invention
can't
be
copied
or
sold
without
their
agreement.
In
exchange,
the
owner
must
reveal
information
about
the
invention.This
contributes
knowledge
that
helps
other
inventors
improve
on
their
own
research.A
patent
usually
lasts
about
20
years.
The
first
step
to
getting
a
patent
is
the
application.The
person
applying
must
name
the
invention,
explain
its
use
and
describe
it
clearly.The
invention
must
be
practical
and
contain
some
new
characteristic—something
that
hasn't
been
seen
or
used
before.But
not
everything
“new”
can
be
patented.Many
countries
don't
allow
patents
on
things
like
new
concepts,
scientific
theories,
medical
procedures
or
substances
already
found
in
nature.
You
may
not
be
able
to
see
patents,
but
they're
connected
to
nearly
everything.There
are
patents
on
things
you
use
every
day,
like
plastic,
medicine
and
your
computer.There
are
patents
on
things
that
are
unavailable
on
the
market,
too.Apple
is
well?known
for
its
patents
on
potential
products,
such
as
the
“iBike”
or
the“iKey”．
Of
course
there
are
also
patents
on
inventions
like
this.Take
the
anti?eating
face
mask
for
example.This
device
locks
around
your
head
with
a
metal
cage
covering
your
mouth.You
can
breathe
and
speak,
but
you
can't
eat!
Although
many
patented
inventions
can
be
failures,
there's
plenty
of
room
for
success.So
if
you
have
a
cool
invention,
try
to
patent
it.
本文是一篇说明文。文章的目的是告知我们申请专利的好处及如何申请专利，同时又介绍了并非所有新的东西都是专利，并建议我们如果有新的发明，就尝试着去申请专利。
1．Which
of
the
following
is
NOT
true
according
to
the
text?
A．A
patent
can
last
for
around
20
years.
B．Everything
new
can
be
patented.
C．Your
invention
is
protected
after
you
have
applied
for
a
patent.
D．Some
patents
are
on
the
things
that
we
use
every
day.
答案：B
解析：细节理解题。从文章第三段第四句“But
not
everything‘new’can
be
patented.”可知，不是所有新的东西都能申请专利。故正确答案为B。
2．We
can
infer
that
Apple's
iBike
is
________.
A．a
popular
product
B．a
mere
new
concept
C．a
famous
brand
in
the
world
D．a
practical
bike
on
the
market
答案：B
解析：推理判断题。从文章第四段倒数一、二句“There
are
patents
on
things
that
are
unavailable
on
the
market，too.Apple
is
well?known
for
its
patents
on
potential
products，such
as
the‘iBike’or
the‘iKey’．”可知，苹果的iBike仅仅是一个新的概念而已，在市场上还买不到。故正确答案为B。
3．The
underlined
word
“device”
in
Paragraph
5
can
best
be
replaced
by
“________”．
A．weapon B．medicine
C．equipment
D．strength
答案：C
解析：词义猜测题。从文章倒数第二段第二句“Take
the
anti?eating
face
mask
for
example.”可知，这个单词的意思与设备有关。A项意为“武器”；B项意为“药品”；C项意为“设备”；D项意为“力量”。故正确答案为C。
4．The
purpose
of
writing
this
passage
is
to
________.
A．advertise
B．persuade
C．warn
D．inform
答案：D
解析：细节理解题。从文章第一段倒数一、二句“Patents
are
the
best
way
to
get
credit
for
your
work
and
help
others
continue
advancing
in
that
field.Here's
what
you
need
to
know.”可知，作者写作的目的是告知我们申请专利的好处。A项意为“登广告”；B项意为“劝说”；C项意为“警告”；D项意为“通知；告知”。故正确答案为D。
Ⅱ.语法填空
There
are
several
reasons
why
school
uniforms
are
a
good
idea.First
of
all，uniforms
help
the
school
look
smart.The
students
feel
that
they
belong
to
a
particular
group.When
every
pupil
in
the
school
wears
the
uniform，nobody
__1__(have)
to
worry
about
fashion(时尚)．Everybody
wears
__2__
same
style
of
clothes.Uniforms
can
be
useful
in
unexpected
ways.A
school
in
Ireland
has
introduced
an
interesting
new
uniform.On
the
edge
of
the
jacket，there
is
a
piece
of
cloth
__3__
gives
off
light
in
the
dark.When
the
children
are
walking
or
__4__(cycle)
to
school
on
dark
mornings，car
drivers
can
__5__(easy)
see
them.
But
can
uniforms
help
improve
school
standards？The
answer
__6__
this
question
is
not
clear.One
study
in
America
found
that
students'
grades
__7__(improve)
a
little
after
the
school
introduced
uniforms.But
some
students
didn't
want
__8__(wear)
the
uniform.Other
American
studies
showed
no
__9__(connect)
between
uniforms
and
school
performance.
School
uniforms
are
__10__(tradition)
in
Britain，but
some
schools
are
starting
to
get
rid
of
them.Some
very
good
schools
don't
have
a
uniform
policy.However，uniforms
are
still
popular.Pupils
at
about
90
percent
of
British
secondary
schools
wear
uniforms.
本文是一篇说明文。文章介绍了校服受欢迎的原因以及各地校服的特点。
1．has/will_have
解析：考查动词的时态和主谓一致。空格前面的从句用了一般现在时，主句谓语动词应该用一般现在时或者一般将来时。而句子主语nobody是第三人称单数，所以当句子为一般现在时态时，谓语动词用第三人称单数。
2．the
解析：考查冠词。此处特指校服的款式相同，the
same...“相同的……”。
3．that/which
解析：考查定语从句的引导词。空格后面的内容用来修饰a
piece
of
cloth，而且在从句中作主语，所以用that或which来引导。
4．cycling
解析：考查动词的时态。因为连词or前面用的是walking，所以空格处应与之并列，用cycle的
?ing形式。
5．easily
解析：考查词性转换。此处修饰动词see，用easy的副词形式。
6．to
解析：考查介词。the
answer
to...“……的答案”。
7．improved
解析：考查时态。主句谓语动词是found，用了一般过去时，此处时态应该与之保持一致。
8．to_wear
解析：考查动词不定式作宾语。want
to
do
sth.“想要做某事”。
9．connection/connections
解析：考查词性转换。no用来修饰名词，此处用单复数形式均可。
10．traditional
解析：考查词性转换。此处形容词作表语，用来说明主语school
uniforms的特点。Unit

the
age
range
required
by
Stewardship
Youth
Ranger
Program?
A．15—18. B．15—24.
C．15—29. D．16—17.
答案：D
解析：细节理解题。根据题干中的关键词Stewardship
Youth
Ranger
Program可直接定位到第三则暑期工作公告。根据本部分中的关键句“Students
aged
16
or
17
at
time
of
hire，but
not
turning
18
before
December
31
this
year.”可知，这个项目的年龄要求是16岁或17岁，且在今年12月31日前不能满18岁，故选D项
“16至17岁”。
3．Which

the
disabled?
A．Jobs
for
Youth.
B．Summer
Company.
C．Stewardship
Youth
Ranger
Program.
D．Summer
Employment
Opportunities.
答案：D
解析：细节理解题。根据题干中的关键词the
disabled(残疾人)可直接定位到最后一则暑期工作公告中的persons
with
a
disability，两者属于典型的同义词替换，故选D项。
B
As
data
and
identity
theft
becomes
more
and
more
common，the
market
is
growing
for
biometric
(生物测量)
technologies—like
fingerprint
scans—to
keep
others
out
of
private
e?spaces.At
present，these
technologies
are
still
expensive，though.
Researchers
from
Georgia
Tech
say
that
they
have
come
up
with
a
low?cost
device
(装置)
that
gets
around
this
problem：a
smart
keyboard.This
smart
keyboard
precisely
measures
the
cadence
(节奏)
with
which
one
types
and
the
pressure
fingers
apply
to
each
key.The
keyboard
could
offer
a
strong
layer
of
security
by
analyzing
things
like
the
force
of
a
user's
typing
and
the
time
between
key
presses.These
patterns
are
unique
to
each
person.Thus，the
keyboard
can
determine
people's
identities，and
by
extension，whether
they
should
be
given
access
to
the
computer
it's
connected
to—regardless
of
whether
someone
gets
the
password
right.
It
also
doesn't
require
a
new
type
of
technology
that
people
aren't
already
familiar
with.Everybody
uses
a
keyboard
and
everybody
types
differently.
In
a
study
describing
the
technology,
the
researchers
had
100
volunteers
type
the
word
“touch”
four
times
using
the
smart
keyboard.Data
collected
from
the
device
could
be
used
to
recognize
different
participants
based
on
how
they
typed，with
very
low
error
rates.The
researchers
say
that
the
keyboard
should
be
pretty
straightforward
to
commercialize
and
is
mostly
made
of
inexpensive，plastic?like
parts.The
team
hopes
to
make
it
to
market
in
the
near
future.

4．Why
do
the
researchers
develop
the
smart
keyboard?
A．To
reduce
pressure
on
keys.
B．To
improve
accuracy
in
typing.
C．To
replace
the
password
system.
D．To
cut
the
cost
of
e?space
protection.
答案：D
解析：推理判断题。根据第二段第一句“Researchers
from
Georgia
Tech
say
that
they
have
come
up
with
a
low?cost
device(装置)
that
gets
around
this
problem:
a
smart
keyboard.”以及第一段最后一句“At
present，these
technologies
are
still
expensive，though.”可推知，研究者研发这种智能键盘是为了降低网络安全保护技术的成本。
5．What
makes
the
invention
of
the
smart
keyboard
possible?
A．Computers
are
much
easier
to
operate.
B．Fingerprint
scanning
techniques
develop
fast.
C．Typing
patterns
vary
from
person
to
person.
D．Data
security
measures
are
guaranteed.
答案：C
解析：推理判断题。根据第二段中的“These
patterns
are
unique
to
each
person.Thus，the
keyboard
can
determine
people's
identities...”可知，正是因为每个人的打字模式不同，这种智能键盘就可以通过分析用户的打字力度及节奏等来判断该用户是不是安全访客，故C项符合题意。
6．What
do
the
researchers
expect
of
the
smart
keyboard?
A．It'll
be
environment?friendly.
B．It'll
reach
consumers
soon.
C．It'll
be
made
of
plastics.
D．It'll
help
speed
up
typing.
答案：B
解析：细节理解题。根据题干“研究者对于智能键盘有什么期望”可直接定位到最后一段的最后一句话“The
team
hopes
to
make
it
to
market
in
the
near
future.”，该团队希望在不久的将来将智能键盘推向市场，故选B项。
7．Where
is
this
text
most
likely
from?
A．A
diary.
B．A
guidebook.
C．A
novel.
D．A
magazine.
答案：D
解析：文章出处题。根据本文的话题“智能键盘”以及第二段中的“Researchers
from
Georgia
Tech
say
that
they
have
come
up
with
a
low?cost
device(装置)．..”，尤其是根据其中的关键词Researchers，low?cost
device等来推断，这篇文章是一篇科研报道，最有可能出现在杂志上。
