一、短文还原,有一项是多余的。
The
earth
is
our
home. It
has
air
that
we
can
breathe(呼吸). It
has
water
for
us
to
drink. It
has
plants
and
animals
that
we
can
eat. The
earth
is
neither
too
hot
nor
too
cold
for
us. 1.
We
are
on
the
earth,but
we
can
see
things
that
are
not
on
the
earth. Early
in
the
morning,
we
can
see
the
sun
come
up. All
day,the
sun
seems
to
move
across
the
sky. 2.
But
the
sun
is
not
really
moving
around
us. We
are
the
ones
who
are
moving. Every
morning, we
turn
toward
the
sun. Every
night, we
turn
away
from
it. Every
year, we
go
around
it. The
earth
is
our
spaceship. 3.
At
night,we
can
often
see
the
moon
and
stars. From
the
earth
stars
look
like
little
points
of
light. But
stars
are
really
big. A
star
is
a
great
number
of
burning
gas. It
gives
off(发出)
light
and
heat. 4.
There
are
eight
planets
moving
around
our
sun. 5.
Some
of
the
planets
have
moons. A
moon
goes
around
a
planet
just
as
a
planet
goes
around
a
star. The
earth
has
only
one
moon. Some
planets
have
more.
A. The
earth
is
the
third
planet
from
the
sun.
B. Late
in
the
day,we
can
see
the
sun
go
down.
C. All
of
us
in
the
ship
are
riding
around
the
sun.
D. Our
sun
is
a
star.
E. But
we
want
to
visit
the
moon
some
day.
F. It
has
everything
we
need
to
live.
二、用方框中所给单词的适当形式完成短文。
astronaut,most,that,imagine,planet,environment,space,live,universe,become
What
will
our
life
be
like

the
year

the
earth

so
many
years. It
is

more

more
crowded
and
polluted. Maybe
people
will
live
on
the
other
4. — Mars. 5.
have
not
been
to
Mars
yet
so
far. Lets
imagine
what
our
life
will
be
like
on
Mars. I
think
life
on
Mars
will
be
better
than
6.
on
the
earth
in
many
ways. People
will
have
more
7. . Robots
will
do
8.
of
work, so
people
will
have
more
time
for
hobbies. Whats
more,there
will
be
no
school
on
Mars. Every
student
will
have
a
computer
at
home. They
can
study,do
their
homework
and
take
exams
online. People
will
travel
more
easily
in
the
9. . Also
the
10.

be
clean. People
wont
need
to
fight
against
pollution
any
more.
