an
“Ivy
League”
China
may
soon
have
( http: / / www.21cnjy.com )its
own
“Ivy
League”,
with
a
union
of
top
universities.
The
term
originally
r
( http: / / www.21cnjy.com )eferred
to
an
athletic
conference
of
eight
top
universities
in
the
northeastern
US.
The
Chinese
version,
which
was
officially
started
in
mid-October,
consists
of
nine
famous
universities,
including
Peking,
Tsinghua,
Zhejiang
and
Fudan.
The
union
is
supposed
to
result
in
student
exchange
programs,
recognition
of
academic
achievements,
and
other
joint
programs.
The
news
of
this
Chin
( http: / / www.21cnjy.com )ese
“Ivy
League”
has
received
mixed
responses
from
the
public
and
press.
Some
negative
critics
have
dismissed
it
as
yet
another
example
of
the
wishful
copying
of
international
practices
without
fully
understanding
them.
Others
say
that
the
“Ivy
League”
is
not
necessary
but
that
the
union
is
a
good
idea,
one
that
could
promote
academic
development.
So
what’s
your
opinion
on
a
Chinese
“Ivy
League”
Do
we
need
one
Yes.
Ivy
Leag
( http: / / www.21cnjy.com )ue
or
not,
nine
of
China’s
best
universities
cooperating
is
a
good
thing.
These
universities
( http: / / www.21cnjy.com )combining
resources
could
create
a
better
environment
for
students
and
for
research.
It
could
also
save
a
lot
of
time
and
resources
because
it
would
mean
fewer
unnecessary
investments
for
some
of
the
universities.
Allowing
students
( http: / / www.21cnjy.com )
to
move
to
or
have
exchanges
with
other
universities
could
broaden
their
horizons,
improve
their
social
skills
and
create
more
employment
opportunities.
The
results
could
be
more
important
than
lessons
and
achievements.
The
term
“Ivy
Lea
( http: / / www.21cnjy.com )gue”
carries
a
sense
of
academic
excellence,
tradition
and
reputation.
If
borrowing
such
a
term
could
encourage
students’
and
professors’
mental
state
and
improve
Chinese
higher
education,
then
there’s
no
reason
not
to
do
it.
No.
Universities
shoul
( http: / / www.21cnjy.com )d
do
some
work
on
increasing
cooperation
instead
of
copying
an
“Ivy
League”
model.
Many
Chinese
( http: / / www.21cnjy.com )universities
already
have
such
cooperation
with
each
other.
If
this
cooperation
were
associated
with
the
“Ivy
League”,
it
would
just
distract
(分散)
attention
and
resources
and
have
a
negative
effect.
These
Chines
( http: / / www.21cnjy.com )e
universities
are
all
state-run
and
most
get
their
funding
from
the
government.
They’re
quite
similar
to
each
other
in
many
ways
and
more
cooperation
wouldn’t
bring
about
as
much
potential
ability
as
between
,
say,
public
and
private,
or
Chinese
and
foreign
universities.
China
should
find
i
( http: / / www.21cnjy.com )ts
own
way
to
develop
world-class
universities
instead
of
by
copying
some
foreign
practices.
We
have
our
own
unique
conditions
and
foreign
lessons
often
don’t
apply
well
here.

三、阅读理解
A段
【2016模拟题】阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
People
believed
for
a
( http: / / www.21cnjy.com )
long
time
that
the
heart
was
the
center
of
a
person's
emotions.
That
is
why
the
word
"heart"
is
used
in
so
many
expressions
about
emotional
situations.
One
such
expression
is
( http: / / www.21cnjy.com )
to
"lose
your
heart"
to
someone.
When
that
happens,
you
have
fallen
in
love.
But
if
the
person
who
won
your
heart
does
not
love
you,
then
you
are
sure
to
have
a
"broken
heart."
In
your
pain
and
sadness,
you
may
decide
that
the
person
you
loved
is
"hard-hearted,"
and
in
fact,
has
a
"heart
of
stone."
You
may
decide
to
"pou
( http: / / www.21cnjy.com )r
out
your
heart"
to
a
friend.
Telling
someone
about
your
personal
problems
can
often
make
you
feel
better.
If
your
friend
( http: / / www.21cnjy.com )
does
not
seem
to
understand
how
painful
your
broken
heart
is,
you
may
ask
her
to
"have
a
heart."
You
are
asking
your
friend
to
show
some
sympathy
for
your
situation.
Your
friend
"has
her
heart
in
the
right
place"
if
she
says
she
is
sorry,
and
shows
great
concern
for
how
you
feel.
Your
friend
may,
( http: / / www.21cnjy.com )
however,
warn
you
not
to
"wear
your
heart
on
your
sleeve."
In
other
words,
do
not
let
everyone
see
how
lovesick
you
are.
When
your
heart
is
on
your
sleeve
you
are
showing
your
deepest
emotions.
If
your
friend
says
"
( http: / / www.21cnjy.com )my
heart
bleeds
for
you,"
she
means
the
opposite.
She
is
a
cold-hearted
person
who
does
not
really
care
about
your
situation.
In
the
ever-popular
( http: / / www.21cnjy.com )
motion
picture,
"The
Wizard
of
Oz,"（绿野仙踪）
the
Tin
Man
seeks
a
heart.
He
wanted
to
feel
the
emotion
of
love,
and
was
seeking
help
from
the
powerful
Wizard
of
Oz
to
find
a
heart.
The
Cowardly
Lion
( http: / / www.21cnjy.com ),
in
the
same
movie,
did
“have
a
heart”.
But
he
lacked
courage
and
wanted
to
ask
the
Wizard
of
Oz
to
give
him
some.
You
could
say
that
the
cowardly
lion
was
"chicken-hearted."
That
is
another
way
of
describing
someone
who
is
not
very
brave.
A
chicken
is
not
noted
for
its
bravery.
Thus,
someone
who
is
chicken-hearted
does
not
have
much
courage.
When
you
are
fri
( http: / / www.21cnjy.com )ghtened
or
concerned,
your
"heart
is
in
your
mouth."
You
might
say,
for
example,
that
your
heart
was
in
your
mouth
when
you
asked
a
bank
to
lend
you
some
money
to
pay
for
a
new
house.
1．What
is
the
main
idea
of
the
passage
A．The
heart

the
center
of
a
person's
emotions.

and

they
mean.
C．We
should
learn
some
expressions
about
“heart”.
D．It
is
important
to
learn
some
expressions
about
“heart”
2．How
many
expressions
about
“Heart”
are
mentioned

heart

the
right
place
C.

your
heart
on
your
sleeve
D.lose
your
heart
4．Why
did
the
writer
mention"The
Wizard

the
passage
A.To
show
that
it
is
ever
popular.

3．推理题：题目问：如果你听说一个家庭
( http: / / www.21cnjy.com )成员在交通事故中受伤，是什么感觉？从最后一段对heart

2016高考训练题。阅读理解。
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
Electric
cars
are
( http: / / www.21cnjy.com )
dirty．In
fact,
not
only
are
they
dirty,
they
might
even
be
more
dirty
than
their
gasoline-powered
cousins．
People
in
Ca
( http: / / www.21cnjy.com )lifornia
love
to
talk
about
“zero-emissions（排放）vehicles,”
but
people
in
California
seem
to
be
clueless
about
where
electricity
comes
from．Power
plants
mostly
use
fire
to
make
it．Aside
from
the
few
folks
who
have
their
roofs
covered
with
solar
cells,
we
get
our
electricity
from
generators（发电机）．Generators
are
fueled
by
something
—
usually
coal,
oil,
but
also
by
heat
generated
in
nuclear
power
plants．There
are
a
few
wind
farms
and
geothermal（地热的）plants
as
well,
but
by
far
we
get
electricity
mainly
by
burning
something．
In
other
words,
t
( http: / / www.21cnjy.com )hose
“zero-emissions”
cars
are
likely
coal-burning
cars．It's
just
because
the
coal
is
burned
somewhere
else
,
so
it
looks
clean．It
is
not．It’s
as
if
the
California
greens
are
covering
their
eyes—“If
I
can’t
see
it,
it’s
not
happening.”
Gasoline
is
an
unbelievably
efficient
way
to
power
a
vehicle;
a
gallon
of
gas
has
a
lot
of
energy
in
it．But
when
you
take
that
gas（or
another
fuel）and
first
use
it
to
make
electricity,
you
waste
a
nice
part
of
that
energy,
mostly
in
the
form
of
wasted
heat—at
the
generator,
through
the
transmission
lines,
etc．
A
gallon
of
gas
( http: / / www.21cnjy.com )may
propel
your
car
25
miles．But
the
electricity
you
get
from
that
gallon
of
gas
won't
get
you
nearly
as
far
—
so
electric
cars
burn
more
fuel
than
gas-powered
ones．If
our
electricity
came
mostly
from
nukes,
or
geothermal,
or
hydro,
or
solar,
or
wind,
then
an
electric
car
truly
would
be
clean．But
for
political,
technical,
and
economic
reasons,
we
don’t
use
much
of
those
energy
sources．
In
addition,
elec
( http: / / www.21cnjy.com )tric
cars’
batteries
which
are
poisonous
for
a
long
time
will
eventually
end
up
in
a
landfill（垃圾）and
finally,
when
cars
are
the
polluters,
the
pollution
is
spread
across
all
the
roads．When
it’s
a
power
plant,
though,
all
the
junk
is
in
one
place．Nature
is
very
good
at
cleaning
up
when
things
are
not
too
concentrated,
but
it
takes
a
lot
longer
when
all
the
garbage
is
in
one
spot．

参考答案1—4、AADB
四、七选五
(2015·长春市质量检测二)
A
great
number
of
peop
( http: / / www.21cnjy.com )le
can
get
injured
or
even
killed
resulting
from
a
human
stampede
(踩踏)．The
bad
thing
is
that
a
peaceful
group
of
people
can
quickly
turn
into
a
crazy
panicked
crowd.
__1__
If
you
are
in
a
crowd,
the
most
important
thing
is
to
make
yourself
familiar
with
your
surroundings
and
mentally
notice
the
exits.
No
matter
where
you
are
make
sure
you
always
know
how
to
get
out.
__2__
If
you
are
in
a
crowd
of
moving
people,
wet
or
uneven
ground
can
be
slippery
or
dangerous,
causing
you
to
fall.
Be
aware
of
the
ge
( http: / / www.21cnjy.com )neral
atmosphere
of
the
event,
as
panic
situations
can
often
be
expected.
When
in
danger,
a
few
seconds
can
make
all
the
difference.
If
you
find
yourself
in
the
middle
of
a
moving
crowd,
do
not
fight
against
the
pressure,
do
not
stand
still
or
sit
down.
__3__
Take
advantage
of
any
space
that
may
open
up
and
try
to
move
sideways
to
the
crowd
movement
where
the
flow
is
weaker.
__4__—It
gives
you
movement
and
protects
your
chest.
If
you
fall,
( http: / / www.21cnjy.com )
get
up
quickly.
If
you
fall
and
cannot
get
up,
keep
moving
by
crawling
in
the
same
direction
of
the
crowd,
or
if
that
is
not
possible,
then
cover
your
head
with
your
arms
and
curl
(蜷缩)up.
__5__
Sometimes,
finding
a
right
posture
can
save
your
life.
A．Make
yourself
aware
of
the
type
of
ground
you
are
standing
on.
B．Do
not
lie
( http: / / www.21cnjy.com )
on
your
stomach
or
back,
as
this
dangerously
exposes
your
lungs.
C．If
you
are
stepped
on,
you
should
shout
for
help.
D．Instead,
move
in
the
same
direction
of
the
crowd.
E．Keep
your
hands
up
by
your
chest,
like
a
boxer.
F．Stretch
your
arm
( http: / / www.21cnjy.com )s
to
the
full
length
so
that
you
can
make
more
space
to
move
in
the
crowd.
G．What's
worse
is
t
( http: / / www.21cnjy.com )hat
the
stampede
can
be
caused
while
there
seems
no
actual
danger.
