八、阅读理解
Many
people
know
that
(?http:?/??/?www.21cnjy.com?)
rubbish
is
a
big
problem
on
planet
Earth.
What
many
people
don't
know
is
that
junk(垃圾)has
become
a
problem
in
outer
space
too.
According
to
B
(?http:?/??/?www.21cnjy.com?)BC
News,
there
are
more
than
22,000
pieces
of
space
junk
floating
around
the
earth.
And
these
are
just
the
things
that
we
can
see
from
the
surface
of
the
earth
by
telescopes(望远镜).
There
are
also
millions
of
smaller
pieces
of
junk
that
we
can't
see.
Objects,
like
bits
(?http:?/??/?www.21cnjy.com?)of
old
space
rockets
or
satellites,
move
around
the
planet
at
very
high
speed,
so
fast
that
even
a
very
small
piece
can
break
important
satellites
or
become
dangerous
to
astronauts.
If
the
tiniest
piece
of
junk
crashed
into
a
spaceship,
it
could
damage
the
vehicle.
To
make
things
worse,
(?http:?/??/?www.21cnjy.com?)when
two
objects
in
space
crash,
they
break
into
many
smaller
pieces.
For
example,
when
a
U.S.
satellite
hit
an
old
Russian
rocket
in
2009,
it
broke
into
more
than
2,000
pieces,
increasing
the
amount
of
space
junk.
To
reduce
addi
(?http:?/??/?www.21cnjy.com?)tional
space
junk,
countries
have
agreed
that
all
new
space
tools
can
only
stay
in
space
for
25
years
at
most.
Each
tool
must
be
built
to
fall
safely
into
the
earth's
atmosphere
after
that
time.
In
the
upper
parts
of
the
atmosphere,
it
will
burn
up.
Many
scienti
(?http:?/??/?www.21cnjy.com?)sts
are
also
suggesting
different
ways
to
clean
up
space
junk.
In
England
scientists
are
testing
a
metal
net
that
can
be
fired
into
space
junk.
The
net
catches
the
junk
and
then
pulls
it
into
the
earth's
atmosphere
to
burn
up.
The
Germans
are
building
robots
that
can
collect
pieces
of
space
junk
and
bring
them
back
to
Earth
to
be
safely
destroyed.
“The
problem
is
(?http:?/??/?www.21cnjy.com?)
becoming
more
challenging
because
we're
sending
more
objects
into
space
to
help
people
use
their
mobile
phones
and
computers,”
says
Marco
Castronuovo,
an
Italian
space
researcher.
“The
time
to
(?http:?/??/?www.21cnjy.com?)act
is
now.
The
longer
we
leave
the
problem,
the
bigger
it
will
become,”
he
says.

water,
but
also
calls

Today,

Among

八、阅读理解
Many
people
kno
(?http:?/??/?www.21cnjy.com?)w
that
rubbish
is
a
big
problem
on
planet
Earth.
What
many
people
don't
know
is
that
junk(垃圾)has
become
a
problem
in
outer
space
too.www.21-cn-jy.com
According
to
BB
(?http:?/??/?www.21cnjy.com?)C
News,
there
are
more
than
22,000
pieces
of
space
junk
floating
around
the
earth.
And
these
are
just
the
things
that
we
can
see
from
the
surface
of
the
earth
by
telescopes(望远镜).
There
are
also
millions
of
smaller
pieces
of
junk
that
we
can't
see.【出处：21教育名师】
Objects,
like
(?http:?/??/?www.21cnjy.com?)
bits
of
old
space
rockets
or
satellites,
move
around
the
planet
at
very
high
speed,
so
fast
that
even
a
very
small
piece
can
break
important
satellites
or
become
dangerous
to
astronauts.
If
the
tiniest
piece
of
junk
crashed
into
a
spaceship,
it
could
damage
the
vehicle.
To
make
things
worse,
(?http:?/??/?www.21cnjy.com?)when
two
objects
in
space
crash,
they
break
into
many
smaller
pieces.
For
example,
when
a
U.S.
satellite
hit
an
old
Russian
rocket
in
2009,
it
broke
into
more
than
2,000
pieces,
increasing
the
amount
of
space
junk.
To
reduce
additio
(?http:?/??/?www.21cnjy.com?)nal
space
junk,
countries
have
agreed
that
all
new
space
tools
can
only
stay
in
space
for
25
years
at
most.
Each
tool
must
be
built
to
fall
safely
into
the
earth's
atmosphere
after
that
time.
In
the
upper
parts
of
the
atmosphere,
it
will
burn
up.
Many
scientist
(?http:?/??/?www.21cnjy.com?)s
are
also
suggesting
different
ways
to
clean
up
space
junk.
In
England
scientists
are
testing
a
metal
net
that
can
be
fired
into
space
junk.
The
net
catches
the
junk
and
then
pulls
it
into
the
earth's
atmosphere
to
burn
up.
The
Germans
are
building
robots
that
can
collect
pieces
of
space
junk
and
bring
them
back
to
Earth
to
be
safely
destroyed.
“The
problem
(?http:?/??/?www.21cnjy.com?)
is
becoming
more
challenging
because
we're
sending
more
objects
into
space
to
help
people
use
their
mobile
phones
and
computers,”
says
Marco
Castronuovo,
an
Italian
space
researcher.
“The
time
to
act
is
no
(?http:?/??/?www.21cnjy.com?)w.
The
longer
we
leave
the
problem,
the
bigger
it
will
become,”
he
says.
