Read
to
learn
Ask
Ss
to
read
the
text
and
check
their
answers
to
Exercise1.Tell
Ss
to
read
through
the
sentences
first
before
they
go
back
to
the
text
and
study
each
paragraph,
and
then
ask
them
to
complete
exercise3
individually,
check
their
answers.
Use
the
Strategies
to
complete
the
gaps
in
the
text
(1-5)
with
these
sentences
(a-g).
There
are
two
extra
sentences
you
do
not
need.
But
evidence
shows
that
73,000
years
ago
there
was
a
much
greater
eruption.
Even
Europe
has
suffered
and
large
areas
have
been
underwater.
That
is
probably
not
the
most
important
factor
either.
Third,
the
other
bits
of
land
you
might
have
been
able
to
farm
are
now
useless.
On
top
of
that
add
global
warming.
For
example,
the
Yellow
River,
once
famous
for
flooding,
failed
to
reach
the
sea
at
all
for
226
days
in
1997.
One
answer
is
overpopulation.
