Could

be
your
town?
Jo
is
fifteen
and
lives
in
Parkville.
When
Jo’s
grandparents
first
came
to
Parkville,
it
was
a
quiet
village.
安静的
They
had
a
small
house,
close
to
fields
and
hills.
Parkville
was
near
Arnwick,
a
city
with
200,000
people.
People
from
Parkville
moved
to
Arnwick
to
find
jobs,
and
they
needed
places
to
live.
However,
it
was
expensive
to
live
in
the
city
centre,
so
the
government
built
flats
outside
the
centre.
Soon,
Parkville
became
part
of
Arnwick,
and
Arnwick
became
a
city
with
over
a
million
people.
Jo’s
family
lives
in
one
of
those
flats.
It
is
very
crowded,
and
rubbish
is
also
a
problem.
家；家庭
The
small
local
school
in
Parkville
closed
down
five
years
ago,
so
Jo
now
has
to
go
to
a
school
in
Arnwick
with
2,000
pupils.
It
takes
an
hour
to
get
there
by
bus.
There
is
a
lot
of
traffic
and
pollution.
当地的；本地的
污染
关闭
It
is
clear
that
Arnwick
needs
more
schools,
buses
and
hospitals.
It
needs
fresh
air,
clean
water
and
better
public
services.
It
also
needs
more
police
to
protect
its
people.
But
to
do
all
these
things,
it
needs
more
money.
公共服务；公共设施
However,
can
money
help
solve
all
these
problems?
Do
we
need
more
big
cities
like
this?
In
fact,
this
is
just
a
story.
But
it
describes
what
is
happening
all
over
the
world.
Could
it
be
your
town
some
day?

Possible
answer
1
Problems:
Many
young
people
want
to
leave
the
countryside
because
they
want
to
find
jobs
in
the
city.
Opinions
and
reasons:
This
is
a
big
problem
for
the
countryside
and
city.
More
and
more
young
people
crowd
into
cities,
so
there
are
few
people
working
in
the
countryside.
But
meanwhile,
there
are
so
many
people
in
the
cities
that
somebody
may
not
find
a
job.
Solutions:
It
may
be
better
to
build
more
universities
and
create
more
jobs
in
smaller
towns
in
the
countryside,
so
young
people
will
find
it
more
interesting
to
stay.
Possible
answer
2
Problems:
Too
much
traffic
brings
air
pollution.
Opinions
and
reasons:
This
is
a
national
as
well
as
an
international
problem.
Goverments
in
every
country
do
not
do
enough
to
control
the
traffic
pollution.
Solutions:
The
governments
should
develop
public
transport
so
that
people
do
not
use
their
cars
so
much
in
the
big
cities.
