again
and
repeat.
In
2010,
the
world's
population
was
about
6.8
billion.
More
than
three
billion
people
live
in
Asia
now.
That's
almost
half
of
the
world's
population.
China
has
the
largest
population
in
the
world,
and
about
one
fifth
of
the
people
in
the
world
live
in
China.
Because
of
the
large
population,
there
is
less
living
space
for
each
family.
And
it
is
difficult
for
lots
of
people
to
find
jobs.
At
the
same
time,
the
large
population
has
caused
many
other
difficulties
for
the
whole
nation.
For
example,
it
is
hard
for
China
to
supply
energy
and
water
to
satisfy
people's
daily
needs.
Most
cities
are
more
crowded
than
before,
and
the
traffic
is
much
heavier.
Natural
environments
are
becoming
worse
and
worse.
The
large
population
has
been
a
serious
problem.
So
far,
our
government
has
taken
many
measures
to
control
the
population.
One
is
known
as
the
one-child
policy.
It
has
worked
well
in
controlling
China's
population.
Thank
to
the
policy,
China
is
developing
quickly
and
people's
living
conditions
are
improving
rapidly.
However,
the
population
problem
is
still
serious
in
China.
We
still
have
a
long
way
to
go.

3a.
One
possible
version:
China
has
the
largest
population
in
the
world.
It
has
caused
many
problems.
Everyone
should
do
something
to
solve
them.
First,
the
government
should
keep
the
one-child
policy
to
control
the
increasing
population,
and
practice
the
reform
and
opening-up
to
develop
our
economy.
Only
in
this
way
can
we
get
more
jobs
and
improve
our
living
conditions.
Second,
the
energy
and
water
is
becoming
less
and
less.
We’d
better
save
them
as
much
as
possible,
and
try
to
find
more
new
energy.
In
order
to
solve
the
problem
of
heavy
traffic,
we
call
on
everyone
to
take
a
bus
or
walk
as
often
as
possible.
