While

This
is
because
about
97%

So
we

How
to
write
a
passage
Write
a
proposal
about
saving
water
to
all
the
students
in
your
school.
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
saving
water.
Make
more
people
around
us
know
the
problem
of
water
shortage
and
how
to
help
solve
it.
Let’s
try
our
best
to
save
water
and
our
planet.
Student
Union
Project
Divide
the
class
into
several
groups:
Water
Group,
Tree
Group,
Soil
Group
…
Each
group
should
discuss
their
own
uses,
the
problems
that
they
face
and
their
wishes.
Then
give
a
report
in
class.
Example:
Uses:
I
am
soil.
Plants
can’t
grow
without
me.
People
use
me
to
make
many
things
…
Problems:
Sometimes
people
use
too
many
chemicals
in
the
fields.
What’s
worse,
they
put
waste
into
the
land
…
So
I’m
hurt.
Please
help
me.
Wishes:
I
hope
human
beings
can
protect
and
take
care
of
me.
And
then
I
could
do
more
useful
things
for
them…
