London
used
to
be
the
biggest
port
in
the
world
.
Many
ships
sail
up
the
River
Thames
to
the
London
Docks
.
These
docks
were
built
____________________
in
the
city
.
There
were
many
docks
.
You
could
stand
on
the
____________________
and
see
ships
of
all
shapes
and
sizes
.
The
ships
were
moving
up
and
down
with
the
tide
.
You
might
have
____________________
that
the
docks
would
last
forever
.
But
____________________
brought
an
end
to
dockland
.
People
started
putting
their
goods
into
____________________
and
building
new
ships
to
carry
them
.
It
made
more
sense
to
build
ports
on
the
coast
.
Then
people
used
trucks
to
bring
the
containers
to
the
coast
.
This
change
____________________
hard
times
to
the
London
Docks
.
