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.
1.
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.
2.
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.
3.
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.
4.
Where
is
this
text
most
likely
from?
A.
A
diary.
B.
A
guidebook.
C.
A
novel.
D.
A
magazine.
【语篇解读】本文是说明文。数据和身份盗窃变得越来越普遍，目前，像指纹扫描等这些技术仍然是昂贵的。本文介绍了一种新的科技——智能键盘，它能给e-space用户带来安全，而且这项技术也不贵。

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.
1.
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.
2.
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.
3.
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.
4.
Where
is
this
text
most
likely
from?
A.
A
diary.
B.
A
guidebook.
C.
A

In
the
1970s,
after
Macquarie
Island
became
an
official
nature
reserve,
the
rabbits
remained
out
of
control.
So
a
plan
to
remove
all
rabbits
was
carried
out.
A
virus
____1_____
(release)
onto
the
island,
which
caused
the
rabbit
population
to
decrease
_____2_____
(dramatic).
____3____
the
saying
goes,
“While
the
cat’s
away,
the
mice
will
play.”
With
the
departure
of
the
cats
from
Macquarie
Island,
the
mouse
and
rat
population
started
to
increase.
And
remember
those
10,000
or
so
rabbits?
It
turned
out
____4____
they
developed
an
immunity
to
the
virus,
and
their
number
exploded
once
again.
Then,
in
2006,
the
rabbits’
____5____
(dig)
caused
some
land
to
collapse,
and
killed
a
substantial
number
of
____6____
(penguin).
This
incident
made
it
clear
that
the
rat,
mouse
and
rabbit
problem
needed
solving
once
and
for
all.
I
am
here
on
the
island
to
participate
____7____
the
programme
to
tackle
this
very
problem.
The
first
step
involved
poison
being
dropped
from
helicopters.
The
next
step
is
to
remove
the
last
____8____(remain)
invading
species,
and
that’s
where
I
come
in-
with
my
dogs.
They
have
been
trained
to
find
every
last
one,
without
harming
the
native
animals.
This
intervention
is
___9____
long,
much-delayed
ending
to
a
sad
story,
but
we
humans
owe
it
to
the
island
to
give____10____
a
happy
ending.
