Ⅰ.阅读理解
[2021·威海模拟]Recently,
researchers
at
the
University
of
Toronto
figured
out
a
way
with
a
quick
video
selfie
to
accurately
measure
blood
pressure
with
your
smartphone's
camera
by
developing
a
technology
known
as
transdermal
optical
imaging
(TOI)
(透皮光学成像)．
Cameras
on
smartphones
can
catch
red
light
reflected
from
hemoglobin
(血红素)under
our
skin,
which
permits
TOI
to
visualize
and
measure
blood
flow
changes.
Researchers
measured
the
blood
pressure
of
1,328
Canadian
and
Chinese
adults
by
getting
two?minute
videos
of
their
faces
on
an
iPhone.
“From
the
video
got
by
the
technology,
you
can
see
how
the
blood
flows
in
different
parts
of
the
face
and
through
this
flow,
you
can
get
a
lot
of
information，”
said
Kang
Lee,
lead
author
of
the
study.
Lee
also
helped
create
an
app
called
Anura,
which
allows
people
to
try
out
the
TOI
software
for
themselves,
giving
them
the
ability
to
record
a
30?second
video
of
their
face
and
receive
measurements
for
stress
levels
and
resting
heart
rate.
Lee
said
more
research
was
needed
to
make
sure
that
the
measurements
were
as
accurate
as
possible,
explaining
that
the
study
didn't
test
people
with
very
dark
or
very
fair
skin.
“In
order
to
improve
our
app
to
make
it
usable,
particularly
for
people
with
hypertension
(高血压)，we
need
to
collect
a
lot
of
data
from
them,
which
is
very
hard
because
a
lot
of
them
are
already
taking
medicine，”
Lee
explained.
“We
cannot
tell
them
not
to
take
medicine,
but
from
time
to
time,
we
get
participants
who
don't
take
medicine
so
we
can
get
hypertensive
people
this
way.”
The
scientists
said
there
were
many
potential
applications
of
the
technology,
including
providing
health
services
for
those
who
lived
in
remote
areas.
1．What
is
mainly
talked
about
in
Paragraph
2?
A．Information
offered
by
TOI.
B．New
findings
on
hypertension.
C．How
TOI
is
put
into
smartphones.
D．How
the
TOI
technology
works.
2．What
might
people
benefit
from
the
new
technology
mentioned
above?
A．Living
a
life
free
from
stress.
B．Improving
the
heart
function
gradually.
C．Accessing
health
services
for
free.
D．Knowing
abnormal
blood
pressure
earlier.
3．What
can
be
done
for
a
better
Anura?
A．Equipping
phones
with
better
cameras.
B．Allowing
phones
to
record
longer
videos.
C．Collecting
data
from
more
diverse
samples.
D．Persuading
participants
not
to
take
medicine.
4．Why
does
the
author
write
this
text?
A．To
predict
future
applications
of
TOI.
B．To
introduce
TOI
and
an
app
related.
C．To
describe
functions
of
cameras
on
phones.
D．To
evaluate
the
quality
of
an
app
called
Anura.

is
in

And
I

I
was
going
to
__1__
my

I
didn't

party
in
the

I
started
thinking
about
doing
a
solo
__2__
somewhere
out
of
the
ordinary.
I
took
out
maps
and
drew
the
1,500?mile
route
along
which
I

__3__
from
the

There
was

around

__13__，
that
wasn't
entirely
true.
There
were
mosquitoes—millions

Ⅲ.读后续写
阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
[2021·泰安模拟]Sara
Savick
remembers
one
special
Easter
when
she
was
nine
years
old.
Her
parents
gave
her
a
baby
duckling
in
a
yellow
basket.
“Mom
said
later
that
she
bought
the
little
duck
because
she
felt
sorry
for
it，”
recalled
Sara.
The
people
at
the
pet
store
colored
the
feathers
pink
for
Easter.
Sara
named
the
duck
Pinky.
Sara's
mother
really
didn't
think
the
baby
duck
would
survive
very
long.
But
to
her
surprise,
Pinky
grew
and
got
stronger
and
stronger.
Soon,
the
little
duckling
was
a
healthy,
hungry
duck
with
white
feathers.
“We
fed
Pinky
oatmeal,
cooked
and
uncooked,
and
small
pieces
of
vegetables，”
said
Sara.
Pinky
lived
inside
the
house
with
Sara
and
her
family.
She
specially
fancied
taking
baths
with
Sara.
Everyone
treated
Pinky
as
a
family
member.
But
just
when
everything
appeared
to
be
perfect,
the
night
of
the
“talk”
came.
Sara's
Mom
and
Dad
sat
her
down,
explaining
that
the
best
thing
for
Pinky
was
to
live
a
normal
duck
life,
with
other
ducks.
It
was
not
natural
for
ducks
to
live
indoors
with
a
family,
her
father
told
her.
He
added
Pinky
needed
to
swim
in
ponds
and
do
all
the
same
things
that
ducks
in
the
wild
do.
Sara
started
to
cry,
knowing
what
was
going
to
happen.
Sara's
parents
decided
to
take
Pinky
to
a
park,
which
was
two
miles
away.
There
was
a
pond
with
a
lot
of
other
ducks.
Pinky
would
have
the
chance
to
live
a
natural
life
and
Sara
could
still
visit
her.
The
big
day
came,
Sara
and
her
parents
put
Pinky
in
a
box
and
drove
to
the
park.
Sara
said
that
Pinky
did
not
look
happy;
maybe
Pinky
was
convinced
that
she
was
a
human,
not
a
duck.
注意：1.续写词数应为150左右；
2．请按如下格式作答。
Everyone
was
sad
when
they
left
Pinky
at
the
pond,
even
Sara's
father.

参考范文：
Everyone
was
sad
when
they
left
Pinky
at
the
pond,
even
Sara's
father.
But
he
tried
to
convince
Sara
that
Pinky
was
fine.
Walking
towards
the
car,
Sara
looked
over
her
shoulder
and
saw
Pinky
standing
alone.
The
other
ducks
were
swimming
around
in
circles,
looking
at
Pinky.
To
Sara,
it
seemed
that
they
were
trying
to
identify
the
strange
animal.
They
didn't
recognize
Pinky
as
a
duck.
Worried
about
Pinky,
Sara
dreamed
of
Pinky
being
bullied
by
other
ducks
the
whole
night.
The
next
morning,
when
looking
out
of
the
kitchen
window,
Sara
couldn't
believe
her
eyes!
There
was
Pinky,
happily
walking
around
on
the
grass.
Thrilled
at
what
she
saw,
she
kept
asking
herself,
“How
did
she
make
it？”
After
all,
it
was
two
miles
away
and
she
managed
to
walk
back
through
the
city
street.
Incredible!
But
her
parents
drove
Pinky
back
to
the
pond
again
regardless
of
her
request.
The
following
morning,
there
was
Pinky
again
on
the
grass!
Seeing
Pinky
again,
her
father
waving
his
arms
about
wildly,
moved
his
lips
without
saying
anything.
Meanwhile,
Sarah,
overjoyed,
hugged
Pinky
tightly,
tears
streaming
down
her
cheeks.
