The
Goal
of
the
Mind
It
was
an
unforgettable
night．The
noisy
Mexico
City
gradually
( 36 )
．The
main
Olympic
stadium
was
in
darkness．
( 37 )
he
finished
making
the
scenes
that
the
marathon
（马拉松赛跑）winners
celebrated
the
victory，Greenspan，a
world
famous
documentary
producer，found
the
stadium
( 38 )
．He
was
leaving
for
the
hotel
when
he
suddenly
saw
a
man
running
into
the
stadium．The
man
ran
out
of
breath．
( 39 )
he
didn’t
stop．After
he
got
to
the
goal，he
fell
down
on
the
ground．Greenspan
( 40 )
this
was
a
marathon
athlete，so
he
went
over
to
ask
why
the
athlete
ran
to
the
goal
with
such
a
difficulty．The
young
man
replied，”That
my
( 41 )
sent
me
here
is
not
to
let
me
start
of
a
race
in
the
competition，but
to
make
me
( 42
)
the
game
I
have
fallen
behind
all
other
runners，but
I
have
a
goal
( 43 )
them．I
will
run
to
the
goal
because
my
motherland
is
watching
me
from
behind．”
Moved
by
what
he
said，Greenspan
( 44 )
the
most
touching
scene
in
the
history
of
the
Olympic
Games
to
every
Corner
of
the
world．
Life
should
have
a
( 45 )
of
reaching
the
peak
（顶峰），yet
the
most
important
is
not
whether
we
can
reach
the
peak
but
whether
we
have
made
the
greatest
efforts-to
reach
the
goal
in
the
mind
is
a
success．

第三部分
阅读理解
(A、B、C、E篇每小题2分，
D篇每小题1分，满分45分)
根据短文内容，从每小题A、B、C三个选项中选出一个最佳答案。
A
Pollution
inside
homes
and
other
buildings
kills
more
than
4
million
people
each
year．Many
people
die
as
a
result
of
breathing
smoke
or
from
cooking
over
wood-powered
of
coal-powered
stoves．
One
way
to
reduce
the
number
of
deaths
is
through
cooking
equipment
powered
by
the
sun．Crosby
Menzies，a
solar
power
expert
in
a
South
African
company，described
his
latest
solar
cooker
called
the“Sol.4”，”It
is
four
square
meters
of
mirrors，six
to
eight
meters
in
length．It
is
quite
a
large
cooler．”
The“Sol.4”works
by
reflecting
（反射）light
from
the
sun
off
large
mirrors．The
mirrors
direct
（把…对准）the
light
at
a
cooking
pan．Then
the
light
heats
the
pan
with
solar
energy．Within
two
minutes，the
pan
is
hot
enough
to
cook
sausages
and
onions．In
just
four
minutes，water
can
be
boiled．That
is
as
fast
as
cooking
with
natural
gas
or
electricity．
The
cooker
is
also
much“friendlier”than
other
models
because
people
do
not
have
to
stand
in
the
sun
to
use
it．And
people
can
prepare
meals
without
having
to
collect
firewood
or
spend
money
on
coal．Such
individuals
would
be
less
likely
to
have
breathing
illnesses
from
harmful
smoke．
At
present，the
cooker
only
works
when
the
sun
is
shining．But
engineers
are
working
on
a
way
to
make
it
work
without
sunlight．
Each
cooker
costs
about
$2000，which
is
a
large
amount
of
money
for
most
Africans．To
solve
that
problem，Crosby
Menzies
has
created
a
non-governmental
organization
called
solar
Cookers
for
Africa．It
plans
to
raise
money
through
donations
to
provide
poor
people
with
solar
cooking
equipment．
46.This
passage
is
mainly
about
______
．
A.solar
cookers B.smoke
pollution
C.breathing
illnesses
47.The“Sol-4”is
mainly
used
to
______
．
A.shorten
the
time
of
cooking
B.reduce
the
cost
of
making
cookers
C.
reduce
the
number
of
deaths
caused
by
harmful
smoke.
48.The
underlined
word“individuals“most
probably
means“
______
”
A.cookers
B.
experts
C.people
49.Which
of
the
following
about
the“Sol-4”is
TRUE？
______
A.It
is
six
to
eight
square
meters
of
mirrors.
B.It
can
work
in
any
weather
condition
now
C.It
is
more
environment-friendly
than
other
cookers.
50.From
the
passage，we
can
infer
that
______
．
A.the“Sol-4”will
be
designed
in
a
smaller
size
B.more
African
can
use
the
solar
cookers
in
the
future
C.the“Sol-4”is
the
first
product
of
the
south
African
company
B
Top
usable
technology
Can
you
wear
your
phone
on
your
wrist(手腕)
Well,
now
you
can.
Apple
Watch,
which
is
like
a
wearable
mini
iPhone,
has
a
square
screen
and
comes
with
many
health
and
fitness
features.
For
example,
it
can
tell
the
user’s
heart
rate.
And
you
can
make
calls
with
it.
However,
it
only
works
together
with
an
iPhone
or
iPad.
And
with
prices
between
$349
to
$17,000,
many
people
may
be
put
off
buying
one.
The
movie
Big
Hero
6
won
many
fans’
hearts.
Now
you
can
take
the
hero
Baymax
home!
But
it
is
much
smaller.
It
is
a
USB
flash
drive
and
it
weighs
only
40g.
You
can
pay
189
Yuan
to
get
one.
Isn’t
it
nice
to
have
a
Baymax
around
when
you
are
working,
playing
games
or
listening
to
some
music
It
seems
that
no
kids
like
thermometers
(温度计).
It
is
too
cold
to
put
under
the
armpit
(腋窝).
And
it
doesn’t
feel
good
to
hold
it
in
the
mouth.
Don’t
worry.
Here
is
the
Temtraq.
It
is
as
thin
as
a
piece
of
paper.
You
just
need
to
stick
it
under
the
arm.
And
you
can
get
the
information
of
your
body
temperature
from
an
app
on
your
phone.
It’s
really
convenient！
