Para
2:
first
point
of
the
argument
and
evidence
Although
cigarette
butts
are
small,
they
are
very
bad
for
the
environment.
Over
1,600
billion
cigarettes
are
smoked
each
year
in
China.
About
4.5
trillion
butts
are
littered
worldwild.
Apart
form
these,
they
contain
some
toxic
chemicals,
which
endanger
the
plants
and
animals.
People
shouldn’t
throw
away
the
butts
but
put
them
in
rubbish
bin
instead.

Plastic
bags
are
another
common
form
of
litter
that
is
a
danger
to
the
environment.
They
are
made
from
oil
and
gas
which
are
non-renewable
resources.
In
China,
2
billion
plastic
bags
are
used
everyday.
They
last
from
20
to
l,000
years.
They
kill
up
to
one
million
seabirds,
100,000
sea
mammals,
countless
fish
worldwide.
It
wouldbe
better
if
peolel
use
fewer
and
recycle
them.

point
of
view
again
and
make
an
appeal
Cleaning
up
your
cigarette
butts
and
plastic
bags
would
improve
the
environment.
The
earth
will
be
a
better
place
because
it
will
be
less
polluted.
And
we
would
know
that
we
were
doing
something
to
look
after
our
planet.
I
believe
the
best
solution
would
be
not
to
smoke
or
use
plastic
bags
at
all.

Possible
version
Hello,
everyone,
Currently,
there
is
a
growing
concern
over
the
environment.
The
environment
around
us
is
getting
worse
and
worse.
For
instance,
in
some
places
we
can’t
see
fish
swimming
or
green
water
in
the
river
because
of
water
pollution.
Our
sky
is
not
cleaner
and
bluer
than
before
due
to
air
pollution.
If?we?don't?protect?our?environment
as
soon
as
possible,?life?will?be?hard?for?us.
Possible
version
So
it
is
quite
important
for
us
to
protect
our
environment.
We
must
spare
no
effort
to
take
a
range
of
measures
to
solve
the
problems.
First
of
all,
our
government
should
build
various
facilities
such
as
sewage
treatment
plants
to
reduce
water
pollution.
In
addition,
another
way
contributing
to
success
of
solving
the
problem
is
recycling
the
waste
paper,
water,
and
other
wastes
so
that
we
can
reuse
them
later.
Possible
version
Last
but
not
least,it
is
suggested
to
use
public
transportation
or
car
sharing
instead
of
private
cars
to
reduce
air
pollution.
In
a
word,
if
everyone
pays
more
attention
to
our
environment,
there
will
be
less
pollution
and
our
life
will
become
better.
Only
if
we
start
out
small,
can
we
save
our
environment.
Therefore,
I'd
like
to
appeal
to
everyone
to
protect
our
environment
and
save
as
much
energy
as
possible
in
our
daily
life.

Suppose
you
are
Li
Hua,
on
behalf
of
your
school
,
you
will
go
to
Australia
to
participate
in
an
exchange
activity
with
the
theme
of
“
WATER
FOR
LIFE”
this
summer
vacation.
In
the
activity,
you
will
make
a
speech
about
water
shortage.
Possible
version
Ladies
and
gentlemen,
Good
morning.
I’m
Li
Hua
from
Beijing,
China.
It’s
my
great
honor
to
be
here
to
say
something
about
the
global
water
shortage
and
ways
of
dealing
with
it.
As
we
all
know,
the
global
water
shortage
is
becoming
worse
and
worse
mainly
because
of
two
reasons
.
One
is
water
pollution,
the
other
is
water
waste.
It’s
high
time
that
we
did
something
to
solve
the
problem.
Firstly,
an
effective
way
is
to
reserve
water
in
a
scientific
way
for
future
use.
Possible
version
Secondly,
our
government
should
start
building
various
facilities
such
as
sewage
treatment
plant
and
encourage
scientists
to
work
out
more
and
better
ways
to
reduce
the
pollution
of
water.
Last
but
not
least,
it’s
everyone’s
responsibility
to
make
good
use
of
water,
such
as
recycling
and
saving
as
much
water
as
possible
in
our
daily
life.
In
a
word,
we
should
be
aware
of
the
situation
of
water
shortage,
and
spare
no
effort
to
protect
water
resources
and
explore
potential
ones
scientifically.
