四、阅读短文，选择正确答案：
Like
all
t
( http: / / www.21cnjy.com )he
planets
in
our
solar
system,
Earth
and
Mars
go
around
the
sun.
But
Earth
is
closer
to
the
sun,
and
therefore
revolves
along
its
orbit(轨道)
more
quickly.
Earth
makes
two
trips
around
the
sun
in
about
the
same
amount
of
time
that
Mars
takes
to
make
one
trip.
So
sometimes
the
two
planets
are
on
opposite
sides
of
the
sun,
very
far
apart,
and
other
times,
Earth
catches
up
with
its
neighbor
and
passes
relatively
close
to
it.
Since
Mars
and
the
( http: / / www.21cnjy.com )sun
appear
on
opposite
sides
of
the
sky,
we
say
that
Mars
is
in
“opposition”.
Mars
oppositions
happen
about
every
26
months.
Every
15
or
17
years,
opposition
occurs
within
a
few
weeks
of
Mars’
perihelion(近日点).
An
opposition
can
occ
( http: / / www.21cnjy.com )ur
anywhere
along
Mars'
orbit.
When
it
happens
while
the
red
planet
is
closest
to
the
sun
(called
“perihelic
opposition”),
Mars
is
particularly
close
to
Earth.
If
Earth
and
Mars
both
had
perfectly
stable
orbits,
then
each
perihelic
opposition
would
bring
the
two
planets
as
close
as
they
could
be.
So,
with
all
these
added
factors,
some
bring
us
closer
together
than
others.
The
2003
opposition
was
the
closest
approach
in
almost
60,000
years!
Mars’
orbit
is
( http: / / www.21cnjy.com )
more
elliptical(椭圆的)
than
Earth’s,
so
the
difference
between
perihelion
and
aphelion(远日点)
is
greater.
Over
the
past
centuries,
Mars’
orbit
has
been
getting
more
and
more
elongated,
carrying
the
planet
even
nearer
to
the
sun
at
perihelion
and
even
farther
away
at
aphelion.
So
future
perihelic
oppositions
will
bring
Earth
and
Mars
even
closer.
Our
2003
record
will
stand
until
August
28,
2287!
1.
Mars
______.
A.
isn’t
one
of

八、阅读短文，回答下列问题。
A
Little
Help
from
the
Sun
Even
though
Mars
( http: / / www.21cnjy.com )doesn't
always
come
close
enough
for
astronomers（天文学家）to
get
a
good
look
at
it
when
Earth
speeds
past,
scientists
have
an
opportunity
to
launch
a
spacecraft
to
Mars
every
26
months.
Unlike
vehicles
( http: / / www.21cnjy.com )in
science
fiction
movies,
spaceships
don't
just
take
off
in
any
direction.
Escaping（避开）Earth's
gravitational
pull
requires
a
lot
of
energy.
Even
then,
without
an
extra
push,
a
spacecraft
would
never
reach
the
orbit
of
Mars.
To
get
a
spacecraft
( http: / / www.21cnjy.com )
to
Mars,
scientists
time
the
launch
so
the
spacecraft
reaches
Mars
when
the
red
planet
is
on
the
opposite
side
of
the
sun
from
Earth.
This
way,
they
take
advantage
of
solar
gravity,
which
causes
a
spacecraft
to
“fall”
toward
the
sun,
traveling
in
an
arc
around
it.
This
motion
follows
physical
laws
described
by
Isaac
Newton
and
Johannes
Kepler
in
the
17th
century.
”What
you
want
to
( http: / / www.21cnjy.com )
do
is
launch
the
spacecraft
so
it
goes
around
the
sun
to
meet
Mars,
”
says
Jah.
“We
give
it
the
least
amount
of
energy
possible
and
let
the
sun's
gravity
do
as
much
as
it
can
for
us.
”
As
a
result,
like
( http: / / www.21cnjy.com )a
warrior
in
a
Roman
chariot
race,
the
spacecraft
comes
up
on
Mars
from
behind.
But
instead
of
sailing
past,
it
slows
down
and
lands.

B：
It
seems
imp
( http: / / www.21cnjy.com )ossible
today,
but
by
the
year
2314,
we
will
be
able
to
live
on
Venus.
Here
is
a
guide
to
what
I
think
life
on
Venus
will
be
like.
First
of
a
( http: / / www.21cnjy.com )ll,
the
temperature
on
Venus
is
too
high
to
support
life.
However,
scientists
will
try
to
find
a
way
to
build
spacesuits
and
space
houses
to
keep
us
cool
and
safe
from
the
heat.
It
will
use
the
power
of
the
sun.
Everything
will
be
very
expensive
on
Venus
because
they
are
from
Earth.
On
Venus,
the
food
will
be
very
dry
and
tasteless.
If
you
have
a
lot
of
money,
you
can
buy
the
food
that
comes
from
Earth
every
week.
The
best
thing
a
( http: / / www.21cnjy.com )bout
life
on
Venus
is
the
transport.
Because
there
are
fewer
people
on
Venus
than
on
Earth,
there
is
more
space
and
fewer
cars
on
the
road.
Also,
high-speed
electronic
trains
connect
people’s
homes
to
everywhere
else.
You
can
go
to
school,
go
shopping,
go
to
work
fast,
safely
and
conveniently,
just
within
minutes.
1.B

B
C：
Even
if
you
are
a
g
( http: / / www.21cnjy.com )ood
high
jumper,
you
can
jump
only
about
seven
feet
off
the
ground.
You
cannot
jump
any
higher
because
the
earth
pulls
you
hard.
The
pull
of
the
earth
is
called
gravity.
You
can
easily
find
out
the
pull
of
the
earth.
If
you
weigh
yourself,
you
will
know
how
much
gravity
is
pulling
you.?Since
there
is
gravity,
water
runs
down
hills.
When
you
throw
a
ball
into
the
air,
it
falls
back
down.
Because
of
gravity,
you
do
not
fall
off
the
earth
as
it
whirls(旋转)
around.?
Then,
can
we
get
awa
( http: / / www.21cnjy.com )y
from
the
earth
and
go
far
away
into
the
space
Now
you
can
do
it,
because
the
spaceships
have
been
invented.
The
spaceship
will
go
so
fast
that
it
can
escape
the
earth
gravity
and
carry
you
into
space.
