Saving
the
Earth
As
time
goes
by,
man
is
making
the
earth
sick.
People
cut
down
too
many
trees
and
leave
rubbish
everywhere.
Factories
let
out
their
waste
without
doing
anything
to
it.
This
has
caused
some
serious
problems.
For
example,
the
land
is
sandy;
the
river
is
dirty;
the
air
is
not
clean
any
more;
even
the
temperature
of
the
earth
is
rising
(the
earth
is
having
a
fever),
and
she
is
shouting
for
help.
What
shall
we
do
to
save
her?
My
suggestion
is
that
we
shoud
plant
mor
trees,
put
the
rubbish
into
dustbins
and
stop
factories
from
pouring
waste
directly
into
the
air
or
rivers
.In
a
word,
we
have
only
one
earth,
and
we
shoud
do
everything
to
protect
it,
or
we
will
regret.

As
we
all
know,
water
pollution
is
becoming
more
and
more
serious.
Some
factories
pour
waste
water
into
the
rivers.
As
a
result,
it
makes
the
water
dirty
and
smell
terrible.
Most

the
water
have
died
and
we
can’t

in

Water
is
very
important
to
human
beings,
so
we
should
do
our
best
to
protect
and
save
it.
Luckily,
our

taking
measures
to
protect
the
water
from
pollution.

My
dear
friends,
Water
is
very
important
to
human
beings.
Let’s
do
something
to
protect
and
save
it.
First,
we
should
protect
our
water
resources
and
not
pollute
them.
The
government
should
also
pass
laws
against
the
water
pollution.
Second,
we
should
save
water
in
our
daily
life,
turn
off
the
taps
in
time,
take
a
shower
instead
of
a
bath,
and
always
remember
to
collect
and
reuse
water.
Third,
let’s
try
to
spread
the
message
about
protecting
and

water.
Make
more

书面表达
你想成为一名环保使者吗？如果你想，你应该做什么？你已经做了什么？请写一篇题为Iwant
to
be
a
greener
person的短文，70词左右。
To
be
a
greeneer
person,
I
think
we
should
do
some
of
these
things:
We
should
help
spread
the
message
about
protecting
the
environment
by
making
speeches
about
the
environment
or
writing
letters
to
the
newspaper.
We
should't
cut
down
many
trees
because
cutting
treeshas
already
affected
the
climate.
When
we
find
factories
pouring
waste
water
directly
into
the
river
or
the
lake,
we
must
write
letters
to
the
newspaper
or
goverment.
We
should
remember
the
three
Rs--reduce,
reuse
and
recycle.
In
my
daily
life,
I
don't
litter.
I
don't
pick
flowers.
I
often
collect
waste
paper,
soft
drink
cans,
plastic
bags
and
bottles.
I
sort
them
so
that
they
can
be
recycle.
I
turn
off
the
lights
when
I
leave
a
room.
Doing
such
things
isn't
enough.
I'll
try
to
do
as
many
things
as
I
can
to
protect
our
environment.
范文：
Thank
you！
