there
was
a
lot
of
traffic
on
the
way
there.
Then
there
were
too
many
people
and
not
enough
space.
It
was
impossible
to
move.
And
there
was
a
lot
of
noise.

Can

Betty:
Over

Betty:
The

That’s
almost

Betty:
But
in
the
future,
China’s
population
won’t
grow
so
fast,
because
families
are
getting
smaller.
