Airplanes
are
the
newest
kind
of
transportation.
From
early
times,
people
tried
to
f

through
the

like

About
100
years
a

someone
took
the
first

on
an
airplane.
This
ride
lasted
for
less
than

These
first
planes
were

too.
Only
one

五、完形填空。
Now

can
pay
by
scanning(扫描）their
faces
while

Is
it
1
to
pay
by
scanning
other
parts
of
our
bodies?
Amazon
has
a
new
technology
that
scans
2
.
The
technology
can
tell
if
the
person
is
the
right
one
by
scanning
his
or
her
hand.
The
scanner
examines
things
such
as
finger
prints.
It
then
sends
a
picture
to
a
certain
center
which
can
decide
who
the
person
is.
In
September
2019,
Amazon
made
a
payment
system
for
a
US
supermarket.
People
can
pay
3
by
scanning
their
hands
under
a
machine.
Their
hand
scan
is
connected
to
their
bank
cards,
so
they
can
pay
successfully.
It's
quite
convenient,
especially
for
4
people.
With

六、阅读理解.

chat
rooms
and
shopping!
The
Interent
is
part
of
our
life
today.
It’s
easy
to
get
onto
the
Internet.
The
only
thing
we
need
to
do
is
to
use
a
modem(调制解调器)
which
is
used
for
connecting
a
computer
to
a
telephone
line.
The
Internet
is
changing
and
growing
all
the
time.
More
and
more
people
have
computers
and
use
the
Internet.
Using
the
Internet
means
surfing
the
World
Wide
Web(that’s
the
“WWW”
you
always
hear
about).
The
Internet
has
a
large
number
of
websites(网站).
They
are
the
places
where
you
go
to
get
information
and
do
things.
Where
do
these
websites
come
from?
They
are
made
by
web
designers.
What
happens
when
you
click
on
a
word
or
a
picture?
You
are
sent
to
another
page.
It’s
all
because
of
the
web
designers.
Web
designers
do
a
lot
of
work
by
using
a
computer
programming(程序编制)
language.
Is
web
design
all
about
computer
programming?
No,
it’s
about
making
something
new.
Web
designers
must
imagine
a
lot
when
they
are
making
a
website.
It
must
look
good
and
be
fun
to
use.
A
big
part
of
web
design
is
art.
They
choose
the
best
pictures
and
colors
to
make
the
website
look
good.
They
also
write
the
things
that
you
see
on
the
website.
An
important
part
of
their
job
is
to
share
ideas
with
the
website
manager
about
how
to
design
the
website
well.
根据短文内容，选择正确答案。

五、完形填空。
Now
people
can
pay
by
scanning(扫描）their
faces
while
shopping.
Is
it
1
to
pay
by
scanning
other
parts
of
our
bodies?
Amazon
has
a
new
technology
that
scans
2
.
The
technology
can
tell
if
the
person
is
the
right
one
by
scanning
his
or
her
hand.
The
scanner
examines
things
such
as
finger
prints.
It
then
sends
a
picture
to
a
certain
center
which
can
decide
who
the

Amazon
made
a

system
for
a
US

People
can
pay
3
by
scanning
their
hands
under
a

Their
hand
scan
is
connected
to
their
bank
cards,
so
they
can
pay
successfully.
It's
quite
convenient,
especially
for
4
people.
With
this
new
technology,
people
5
take
their
cards
with
them.
They
just
scan
their
hands.
1．A．possible
B．important
C．strange
【答案】A
【解析】句意：有没有可能通过扫描我们身体的其他部位来支付呢？possible可能的；important重要的；strange奇怪的。分析上下文可知，此处表示目前人们可以通过面部识别技术进行支付，那么扫描其他部位可不可能进行支付呢？强调“可能的”，故选A。
2．A．eyes
B．faces
C．hands
【答案】C
【解析】句意：亚马逊有一项扫描人手的新技术。eyes眼睛；faces面部；hands手。根据后文“The
technology
can
tell
if
the
person
is
the
right
one
by
scanning
his
or
her
hand.”可知，是通过扫描手部进行识别的。故选C。
3．A．usually
B．simply
C．really
【答案】B
【解析】句意：人们只需在机器下面扫描自己的手就可以支付。usually通常；simply简单地；really真地。分析句子可知，此处表示“人们只需在机器下面扫描自己的手就可以支付”的含义，强调方式简单，其他两项语意不通。故选B。
4．A．old
B．poor
C．smart
【答案】A
【解析】句意：它很方便，尤其是对老年人来说。old年老的；poor贫穷的；smart聪明的。根据前文“Their
hand
scan
is
connected
to
their
bank
cards,
so
they
can
pay
successfully.”可知，他们的手扫描与他们的银行卡相连，所以他们可以成功支付，方式非常简单，所以适合老人使用，其他两项不符合语境。故选A。
5.
A．mustn't
B．can't
C．needn't
【答案】C
【解析】句意：有了这项新技术，人们就不需要随身携带信用卡了。mustn't禁止；can't不能；needn't不需要。分析上下文可知，这项技术只需扫描手即可完成支付，所以很方便，不需要随身携带信用卡了，此处强调必要性。故选C。
