A
Grandma,
almost
ninety
years
old,
sat
weakly
on
the
park
bench.
She
didn't
move.
She
just
sat
with
her
head
down
staring
(凝视)
at
her
hands.
When
I
sat
down
beside
her,
she
didn't
even
notice
me.
I
wondered
if
she
was
OK.
So
I
asked
her
if
she
was
OK.
She
raised
her
head,
looked
at
me
and
said
with
a
smile,
“Yes,
I'm
fine.
Thank
you
for
asking
me.”
“I
didn't
mean
to
disturb
you,
Grandma,
but
you
were
just
sitting
here
staring
at
your
hands
and
I
wanted
to
make
sure
you
were
OK，”
I
explained
to
her.
“Have
you
ever
looked
at
your
hands？”
she
asked.
“I
mean
really
looking
at
your
hands.”
I
slowly
opened
my
hands
and
stared
down
at
them.
And
then
I
turned
them
over.
No,
I
guess
I_had_never_really_looked_at_my_hands
as
I
tried
to
figure
out
the
point
my
grandma
was
making.
Grandma
smiled
and
told
me
the
following
story,
“My
hands
put
food
in
my
mouth
and
clothes
on
my
back.
They
tied
my
shoes
and
pulled
on
my
boots.
They
held
my
husband
and
wiped
my
tears
when
he
went
off
to
war.
They
were
uneasy
when
I
tried
to
hold
my
newborn
son.
Decorated
with
my
wedding
band,
they
showed
the
world
that
I
was
married
and
loved
someone
special.
They
wrote
my
letters
to
him
and
shook
when
I
buried
my
parents.
They
held
my
children
and
grandchildren
and
comforted
my
neighbors.
They
covered
my
face,
combed
(梳)
my
hair
and
washed
the
rest
of
my
body.
These
hands
are
the
mark
of
where
I've
been
and
the
ruggedness
(崎岖)
of
life.”
I
never
look
at
my
hands
the
same
again.
When
my
hands
are
hurt
or
when
I
touch
the
faces
of
my
children
and
my
husband,
I
think
of
my
grandma.
I
know
I
can
also
create
a
bright
future
using
my
hands.

Teenagers'
fitness
is
now
a
major
concern,
to
which
physical
exercise
is
very
important.
It
reduces
stress
and
improves
fitness.
Exercise
makes
your
body
strong,
and
helps
you
to
keep
the
right
body
weight.
Sports
scientist
Dr.
Helen
Lopez
offers
the
following
advice
to
teenagers：“First,
you
need
to
find
out
your
present
level
of
fitness.
Then
you
can
design
a
programme
that
will
help
you
become
healthier.”
Dr.
Lopez
suggests
that
there
are
three
levels
of
fitness
that
need
a
change
of
lifestyle.
“Overweight”
means
that
the
person
gets
very
little
exercise
and
often
has
a
serious
weight
problem.
“Inactive”
means
that
the
person
does
not
join
in
many
physical
activities,
but
is
not
seriously
overweight.
“Active”
refers
to
people
who
take
part
in
sports
and
other
physical
activities,
but
are
not
at
a
high
fitness
level.
According
to
Dr.
Lopez,
overweight
teenagers
should
keep
active
to
keep
healthy.
“Ride
a
bike,
play
volleyball
or
basketball
for
a
while,
and
go
for
a
twenty?minute
walk
each
day.
All
these
will
help
to
burn
calories.”
Inactive
teenagers
should
do
similar
activities,
but
add
some
bending
and
stretching
exercises,
such
as
push?ups
and
sit?ups,
starting
with
twenty
each
day.
“Inactive
people
can
take
a
little
more
exercise
than
overweight
people
because
their
bodies
are
stronger，”
said
Dr.
Lopez.
The
same
principle
applies
to
active
teenagers.
Dr.
Lopez
suggests
one
hour
a
week
or
more
on
running
and
other
forms
of
intensive
exercise
(强化训练),
together
with
fifteen
minutes
a
day
spent
on
stretching
and
bending
activities.
“These
are
really
important
in
order
to
prevent
injuries，”
Dr.
Lopez
said.
Some
weight?training
and
other
body?strengthening
exercises
could
also
be
planned
in
the
programme
in
order
to
increase
the
person's
strength.
5．Why
is
physical
exercise
important?
A．It
can
make
the
teenagers
grow
taller.
B．It
can
help
teenagers
become
healthier.
C．It
can
help
teenagers
to
lose
weight.
D．It
can
change
teenagers'
lifestyles.
6．What
can
we
learn
from
the
passage?
A．Active
people
are
always
at
a
high
fitness
level.
B．Overweight
people
always
take
more
exercise.
C．Inactive
teenagers
are
not
seriously
overweight.
D．Keeping
fit
means
changing
teenagers'
lifestyle.
7．In
order
to
prevent
injuries,
what
kind
of
exercise
should
you
do?
A．Walking.
B．Stretching
and
bending.
C．Riding.
D．Weight?training.
8．What
is
the
best
title
for
the
passage?
A．Doing
Exercise
B．Teenagers'
Fitness
C．Different
Lifestyles
D．Overweight
Teenagers

Most
people
who
own
iPhones
use
them
as
their
alarm
clocks
—
making
it
very
easy
to
check
emails
one
last
time
before
falling
asleep
and
hard
to
ever
feel
away
from
work
and
social
networks.
Several
years
ago,
my
boss
fainted
due
to
exhaustion
after
staying
up
late
to
catch
up
on
work.
She
banged
her
head
and
ended
up
with
five
stitches
(缝针)
—
and
became
what
she
calls
a
“sleep
evangelist
(传教士)．”
Now
she
leaves
her
phone
charging
in
another
room
when
she
goes
to
bed
and
encourages
her
friends
to
do
the
same.
“I
sent
all
my
friends
the
same
Christmas
gift
—
a
lovely
alarm
clock
—
so
they
could
stop
using
the
excuse
that
they
needed
their
very
attractive
iPhones
by
their
beds
to
wake
them
up
in
the
morning.”
she
said.
If
your
phone
wakes
you
up
in
the
morning,
it
may
also
be
keeping
you
up
at
night.
A
2008
study
showed
that
people
exposed
to
mobile
radiation
took
longer
to
fall
asleep
and
spent
less
time
in
deep
sleep.
“The
study
indicates
that
during
laboratory
exposure
to
884
MHz
wireless
signals,
components
of
sleep
believed
to
be
important
for
recovery
from
daily
wear
and
tear
are
severely
affected，”
the
study
concluded.
A
quarter
of
young
people
feel
like
they
must
be
available
by

around

according
to
a
Swedish

heavy

I
first
began
experiencing
anxiety
and
depression
at
the
age
of
14,
after
being
bullied
(欺凌)
at
school
for
years.
While
at
first
anxiety
and
depression
would
come
and
go,
it
eventually
became
a
constant
part
of
my
life.
I
was
so
eager
to
find
the
solution
to
overcoming
my
anxiety
and
depression
that
I
tried
everything
from
when
I
was
in
college
to
graduate
school:
mood?changing
medication,
special
teas,
yoga,
anything
I
read
about
in
books,
and
advice
given
by
doctors.
Despite
this,
I
still
felt
I
hadn't
even
come
close
to
managing
the
problem.
But
one
afternoon,
my
eyes
fell
upon
an
article
in
a
magazine
I
was
reading
that
talked
about
how
dogs
were
able
to
help
people
with
anxiety
and
depression.
The
very
next
day,
I
decided
to
get
a
dog
—
a
corgi.
When
I
brought
my
little
corgi,
Buddy,
home,
I
didn't
realize
how
much
he
would
change
my
life.
It
didn't
happen
right
away,
however.
Once
the
“puppy
excitement”
went
away,
my
anxiety
and
depression
came
back
as
usual.
One
morning,
I
woke
up
with
those
familiar
feelings
again.
I
didn't
want
to
get
out
of
bed.
I
turned
to
pull
the
covers
back
over
my
head
and
gave
up.
That's
when
I
saw
Buddy.
Buddy
started
jumping
all
over
me,
licking
my
face,
letting
me
know
that
it
was
time
to
go
outside.
It
was
as
if
he
were
saying,
“There's
no
time
to
be
sad,
the
world
is
amazing！”
And
for
the
first
time
in
my
life,
my
life
was
changing.
I
really
was
a
new
person.
This
was
my
new
beginning.
It's
been
more
than
a
year
since
that
day,
and
I've
never
spent
another
morning
unable
to
get
out
of
bed.
I've
not
cried
myself
to
sleep
or
spent
my
days
stuck
with
fear
and
regret.
Sure,
I
still
have
days
when
I
feel
sad
or
anxious.
But
with
Buddy,
my
best
friend,
by
my
side,
I've
finally
learned
how
to
manage
these
feelings
and
emotions.

depression?

it
forward
to

Ⅲ.概要写作
阅读下面短文，根据其内容写一篇60词左右的内容概要。
It
is
generally
believed
that
scientific
research
should
improve
our
quality
of
life.
Meanwhile,
there
is
almost
universal
agreement
that
the
government
should
provide
financial
and
political
support
for
any
research
that
is
likely
to
result
in
immediate
and
significant
benefits
for
the
majority
of
people.
However,
when
it
comes
to
whether
the
government
should
support
scientific
research
with
no
practical
use,
people's
ideas
vary.
I
agree
with
the
statement
that
the
government
should
distribute
enough
funds
to
any
scientific
research
that
aims
to
improve
the
well?being
of
people,
even
if
it
is
of
no
practical
use
in
the
short
run.
Scientific
research
whose
social
benefits
are
immediate,
predictable,
and
far?reaching
should
continue
to
be
a
high
priority
(优先事项).
For
example,
biotechnology
research
has
been
proven
to
help
cure
and
prevent
diseases;
advances
in
medical
technology
make
it
possible
to
offer
safer
treatments;
information
technology
enables
education
to
be
more
accessible;
and
communication
technology
promotes
global
peace
by
improving
mutual
understanding
among
people
and
their
participation
in
the
democratic
(民主的)
process.
However,
this
is
not
to
say
that
research
whose
benefits
are
less
immediate
or
clear
should
be
given
a
lower
priority.
It
is
difficult
to
predict
what
research
will
finally
lead
to
the
greatest
contributions
to
society.
Unwillingness
to
finance
less
practical
scientific
research
could
have
a
harmful
effect
on
the
efforts
to
explore
new
knowledge.
This
is
particularly
true
of
the
computer
science.
For
example,
before
the
first
computer
was
invented,
public
opinions
went
against
it,
as
most
people
saw
nothing
practical
in
computer
research.
However,
computers
transformed
the
way
human
society
developed
and
proved
to
be
of
great
use
in
the
long
run,
especially
in
terms
of
scientific
development
in
fields
such
as
the
military,
medicine,
aviation,
and
education.
Therefore,
never
should
we
think
that
scientific
research
whose
benefits
are
unknown
is
not
worth
undertaking
since
the
purpose
of
any
research
should
be
to
discover
the
truth,
whatever
it
might
be.

Ⅲ.概要写作
【语篇解读】 Paragraph
1：人们普遍认为，科学研究应该有助于提升生活质量，政府应该给可能会给大多数人带来即时、显著社会效益的研究提供经济和政治支持。但当谈及政府是否应该支持没有实际用途的科学研究时，人们观点不一。我的观点是，政府应该分配足够的资金给予任何一个旨在促进人类幸福的科学研究，即使从短期来看，它没有实际用途。
Paragraph
2：那些能够产生即时的、可预测的、意义深远的社会效益的科学研究应该继续被作为重点项目来对待。
Paragraph
3：但是，这并不是说那些所产生的社会效益不会那么即时、明显的研究就应该被列为非重点项目。很难判断什么样的研究最终会对社会作出巨大贡献。
Paragraph
4：因此，我们绝不能认为那些社会效益不确定的科学研究就不值得进行，因为不管是什么样的研究，其目的都是了解真相。
There
exists
disagreement
about
whether
the
government
should
support
scientific
research
without
immediate
benefits,
but
I
think
it
essential
to
fund
it
for
its
potential
contribution.
(要点1)
It's
universally
accepted
that
scientific
research
with
instant
and
significant
social
benefits
should
be
given
privileges.
(要点2)
But
it
doesn't
mean
less
attention
to
research
having
no
immediate
or
obvious
social
benefits,
for
it
may
eventually
make
unexpected
contributions.
(要点3)
In
short,
all
scientific
research
deserves
equal
attention
and
support
considering
its
aim
of
exposing
the
truth.
(要点4)
