We
all
know
that
exercise
is
good
for
your
health，but
some
kinds
of
exercise
may
be
better
than
others.
Running，for
example，may
help
to
protect
against
heart
disease
and
other
health
problems.Running
may
also
help
you
live
longer.Researchers
say
it
is
not
important
how
far
you
run.It
also
does
not
matter
how
fast
or
even
how
often
you
run.As
advertisements
for
the
running
shoe
Nike
say，“Just
do
it.”
Recently，researchers
studied
more
than
55,000
adults.About
one?fourth
of
the
adults
reported
running
regularly.The
study
found
these
runners
were
considerably
less
likely
than
non?runners
to
die
of
any
form
of
disease，including
heart
disease.In
fact，the
runners
usually
lived
three
years
longer
than
the
non?runners.
This
study
lasted
15
years.During
that
time，more
than
3,400
of
the
individuals
died.About
1,200
of
the
deaths
were
linked
to
heart
disease，a
heart
attack
or
a
pared
to
non?runners，runners
showed
30
percent
lower
risk
of
death
by
any
causes.Also，runners
compared
to
non?runners
showed
45
percent
lower
risk
of
death
by
cardiovascular(心血管的)
disease.
The
runners
in
the
study
ran
between
10
and
16
kilometers
per
hour.Slower
runners，and
those
who
only
ran
once
or
twice
a
week，were
helped
nearly
as
much
as
those
who
ran
faster
and
further.Researchers
looked
at
the
running
over
time
and
found
that
persistent
runners—over
six
years—showed
the
biggest
benefits.
To
stay
healthy，doctors
suggest
that
adults
up
to
age
65
do
150
minutes
of
moderate(适度的)
exercise
every
week.They
say
these
individuals
need
75
minutes
of
energetic
exercise，like
running，every
week
for
good
health.

B
Michelle
Kwan
is
a
champion
ice
skater
who
has
won
five
World
Championships，nine
U．S.Championships
and
two
Olympic
medals，in
addition
to
countless
other
skating
competitions.While
audiences
have
seen
her
glide
effortlessly
across
the
ice，long
hours
of
practice
and
devotion
contribute
each
jump
and
spin.
Kwan
began
ice
skating
when
she
was
five
years
old，and
her
skill
quickly
became
evident.At
the
age
of
eight，she
skated
several
hours
a
day，every
day
of
the
week.Before
school，after
school
and
on
weekends，she
was
at
the
ice
rink.The
cost
of
ice
time
and
coaches
quickly
grew，but
her
parents
were
committed
to
her
success.Her
family
sold
their
home
and
purchased
a
much
smaller
one
to
free
up
money
to
pay
for
her
ice
skating.
When
Kwan
was
13，she
performed
at
her
first
U．S.National
Championships.After
a
disappointing
performance，she
swore
to
work
even
harder
and
improve.She
did.The
next
year，she
finished
second.From
there
she
went
on
to
win
a
silver
medal
at
the
1998
Olympics
and
the
first
of
her
World
Championships.She
followed
up
with
a
bronze
medal
at
the
2002
Olympic
Games.
Kwan
is
the
most
decorated
figure
skater
in
American
history.She
was
the
sole
member
to
the
U．S.Figure
Skating
Hall
of
Fame
and
the
World
Figure
Skating
Hall
of
Fame
classes
of
2012，and
in
2014，she
was
appointed
to
the
Hall
of
Fame
at
the
U．S.National
Competition.
Even
after
retiring
from
skating，Kwan
has
not
given
up
her
devotion
to
learning，service
and
hard
work.She
received
her
college
degree
in
2009
from
the
University
of
Denver
and
is
pursuing
graduate
studies
in
international
relations
at
Tufts
University.Meanwhile，she
has
held
several
diplomatic
and
ambassador
positions
representing
the
United
States
globally.Ultimately，whether
on
the
ice，in
the
classroom
or
representing
her
nation，Kwan
presents
one
consistent
quality—devotion.
5．What
do
we
know
about
Kwan
according
to
the
text?
A．She
performed
badly
in
her
first
national
competition.
B．She
has
won
five
U．S.Championships.
C．She
failed
to
graduate
from
Tufts
University.
D．She
hasn’t
won
the
second
place
in
Olympic
Games.
6．Which
of
the
following
can
best
describe
Kwan?
A．Warm?hearted.
B．Energetic.
C．Easygoing.
D．Devoted.
7．What
may
be
the
best
title
for
the
text?
A．The
Way
to
Success
B．A
Great
Skater
C．How
to
Be
a
Good
Player
D．Why
Is
Devotion
Important?
【语篇解读】这是一篇说明文。关颖珊是著名的滑冰运动员，曾经获得五次世界冠军，九次美国全国冠军，两枚冬奥会奖牌，被认为是历史上最伟大的花样滑冰选手。
5．答案A
解析：细节理解题。根据第三段前两句“When
Kwan
was
13，she
performed
at
her
first
U．S.National
Championships.After
a
disappointing
performance，she
swore
to
work
even
harder
and
improve.”可知，Kwan在第一次全国比赛中表现很差，故选A。
6．答案D
解析：推理判断题。根据最后一段最后一句“Ultimately，whether
on
the
ice，in
the
classroom
or
representing
her
nation，Kwan
presents
one
consistent
quality—devotion.”可知，最终无论是在冰上，在教室里或代表她的国家，她都呈现了一个始终如一的品质：奉献。故选D。
7．答案B
解析：标题归纳题。文章主要介绍了著名滑冰运动员关颖珊，她曾经获得五次世界冠军、九次美国全国冠军和两枚冬奥会奖牌，被认为是历史上最伟大的花样滑冰选手。故文章介绍了“一位伟大的滑冰运动员”，故选B。

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。
Junior
Alvarado
was
worried
when
he
began
his
first
year
at
a
public
charter(特许)
high
school
in
Washington，D.C.He
often
struggled
in
his
math
classes
and
earned
poor
grades
in
middle
school.But
the
teachers
at
the
Washington
Leadership
Academy
used
computer
programs
to
identify
the
areas
he
was
weak
in
and
design
a
learning
plan
just
for
him.
As
Alvarado
started
geometry
in
his
second
year
of
high
school
last
week，he
said
he
felt
much
better
about
his
math
skills.“For
me
personalized
learning
is
having
classes
set
at
your
level，”
the
15?year?old
said，in
between
lessons.“They
explain
the
problem
step
by
step.The
speed
isn’t
fast.It
is
at
your
speed.”
Many
schools
in
the
United
States
struggle
to
raise
the
high
school
graduation
rate.They
also
have
difficulty
helping
many
minority
and
low?income
students
perform
at
the
same
level
as
others.So
many
educators
see
digital
technology
as
a
way
of
solving
these
problems.
Personalized
learning
is
a
way
of
teaching
centered
around
the
interests
and
needs
of
individual
students
instead
of
entire
classes
as
a
whole.It
includes
flexible(灵活的)
learning
environments，specially?designed
education
plans，and
letting
students
help
decide
what
and
how
they
learn.
Still，many
researchers
say
it
is
too
early
to
tell
if
personalized
learning
works
better
than
traditional
teaching.
RAND
Corporation
recently
did
a
study
of
personalized
learning
and
found
that
it
only
led
to
small
improvements.It
found
only
a
3?percentile
improvement
in
math
and
even
smaller
improvements
in
reading
compared
to
schools
with
traditional
teaching
methods.Some
students
also
complained
group
work
in
personalized
learning
classes
was
more
difficult
as
each
student
had
different
tasks
to
complete.In
addition，experts
in
children’s
health
say
the
overuse
of
technology
presents
other
problems.They
warn
that
too
much
time
looking
at
screens
can
damage
face?to?face
relationships
and
young
people’s
interest
in
physical
activity.
Some
teachers
have
their
doubts
as
well.Marla
Kilfoyle
is
the
executive
director
of
the
Badass
Teachers
Association，an
education
activist
group.She
admits
that
technology
can
be
helpful
in
the
classroom
in
many
ways.But
she
argues
that
no
computer
program
should
ever
replace
the
personal
touch，support
and
inspiration
teachers
give
their
students.

non?runners
to
die
of
any
form
of
disease，including
heart
disease.In
fact，the
runners
usually
lived
three
years
longer
than
the
non?runners.
This
study
lasted
15
years.During
that
time，more
than
3,400
of
the
individuals
died.About
1,200
of
the
deaths
were
linked
to
heart
disease，a
heart
attack
or
a
pared
to
non?runners，runners
showed
30
percent
lower
risk
of
death
by
any
causes.Also，runners
compared
to
non?runners
showed
45
percent
lower
risk
of
death
by
cardiovascular(心血管的)
disease.
The
runners
in
the
study
ran
between
10
and
16
kilometers
per
hour.Slower
runners，and
those
who
only
ran
once
or
twice
a
week，were
helped
nearly
as
much
as
those
who
ran
faster
and
further.Researchers
looked
at
the
running
over
time
and
found
that
persistent
runners—over
six
years—showed
the
biggest
benefits.
To
stay
healthy，doctors
suggest
that
adults
up
to
age
65
do
150
minutes
of
moderate(适度的)
exercise
every
week.They
say
these
individuals
need
75
minutes
of
energetic
exercise，like
running，every
week
for
good
health.

Michelle
Kwan
is
a
champion
ice
skater
who
has
won
five
World
Championships，nine
U．S.Championships
and
two
Olympic
medals，in
addition
to
countless
other
skating
competitions.While
audiences
have
seen
her
glide
effortlessly
across
the
ice，long
hours
of
practice
and
devotion
contribute
each
jump
and
spin.
Kwan
began
ice
skating
when
she
was
five
years
old，and
her
skill
quickly
became
evident.At
the
age
of
eight，she
skated
several
hours
a
day，every
day
of
the
week.Before
school，after
school
and
on
weekends，she
was
at
the
ice
rink.The
cost
of
ice
time
and
coaches
quickly
grew，but
her
parents
were
committed
to
her
success.Her
family
sold
their
home
and
purchased
a
much
smaller
one
to
free
up
money
to
pay
for
her
ice
skating.
When
Kwan
was
13，she
performed
at
her
first
U．S.National
Championships.After
a
disappointing
performance，she
swore
to
work
even
harder
and
improve.She
did.The
next
year，she
finished
second.From
there
she
went
on
to
win
a
silver
medal
at
the
1998
Olympics
and
the
first
of
her
World
Championships.She
followed
up
with
a
bronze
medal
at
the
2002
Olympic
Games.
Kwan
is
the
most
decorated
figure
skater
in
American
history.She
was
the
sole
member
to
the
U．S.Figure
Skating
Hall
of
Fame
and
the
World
Figure
Skating
Hall
of
Fame
classes
of
2012，and
in
2014，she
was
appointed
to
the
Hall
of
Fame
at
the
U．S.National
Competition.
Even
after
retiring
from
skating，Kwan
has
not
given
up
her
devotion
to
learning，service
and
hard
work.She
received
her
college
degree
in
2009
from
the
University
of
Denver
and
is
pursuing
graduate
studies
in
international
relations
at
Tufts
University.Meanwhile，she
has
held
several
diplomatic
and
ambassador
positions
representing
the
United
States
globally.Ultimately，whether
on
the
ice，in
the
classroom
or
representing
her
nation，Kwan
presents
one
consistent
quality—devotion.

概要写作

Junior
Alvarado
was
worried
when
he
began
his
first
year
at
a
public
charter(特许)
high
school
in
Washington，D.C.He
often
struggled
in
his
math
classes
and
earned
poor
grades
in
middle
school.But
the
teachers
at
the
Washington
Leadership
Academy
used
computer
programs
to
identify
the
areas
he
was
weak
in
and
design
a
learning
plan
just
for
him.
As
Alvarado
started
geometry
in
his
second
year
of
high
school
last
week，he
said
he
felt
much
better
about
his
math
skills.“For
me
personalized
learning
is
having
classes
set
at
your
level，”
the
15?year?old
said，in
between
lessons.“They
explain
the
problem
step
by
step.The
speed
isn’t
fast.It
is
at
your
speed.”
Many
schools
in
the
United
States
struggle
to
raise
the
high
school
graduation
rate.They
also
have
difficulty
helping
many
minority
and
low?income
students
perform
at
the
same
level
as
others.So
many
educators
see
digital
technology
as
a
way
of
solving
these
problems.
Personalized
learning
is
a
way
of
teaching
centered
around
the
interests
and
needs
of
individual
students
instead
of
entire
classes
as
a
whole.It
includes
flexible(灵活的)
learning
environments，specially?designed
education
plans，and
letting
students
help
decide
what
and
how
they
learn.
Still，many
researchers
say
it
is
too
early
to
tell
if
personalized
learning
works
better
than
traditional
teaching.
RAND
Corporation
recently
did
a
study
of
personalized
learning
and
found
that
it
only
led
to
small
improvements.It
found
only
a
3?percentile
improvement
in
math
and
even
smaller
improvements
in
reading
compared
to
schools
with
traditional
teaching
methods.Some
students
also
complained
group
work
in
personalized
learning
classes
was
more
difficult
as
each
student
had
different
tasks
to
complete.In
addition，experts
in
children’s
health
say
the
overuse
of
technology
presents
other
problems.They
warn
that
too
much
time
looking
at
screens
can
damage
face?to?face
relationships
and
young
people’s
interest
in
physical
activity.
Some
teachers
have
their
doubts
as
well.Marla
Kilfoyle
is
the
executive
director
of
the
Badass
Teachers
Association，an
education
activist
group.She
admits
that
technology
can
be
helpful
in
the
classroom
in
many
ways.But
she
argues
that
no
computer
program
should
ever
replace
the
personal
touch，support
and
inspiration
teachers
give
their
students.
