Hello
and
welcome
to
Six
Minute
Vocabulary
.
I'm
Catherine
,
and
I'm
.
You
know
,
Catherine
,
six
minute
vocabulary
is
great
because
you
can
listen
to
each
program
again
and
again
,
you
can
you
can
reuse
them
.
You
can
.
And
the
word
reuse
is
a
clue
to
today's
topic
.
It
is
.
We're
talking
about
prefixes
.
Those
are
the
two
or
three
letters
that
we
can
add
to
the
beginning
of
words
to
change
their
meaning
,
like
re
in
reuse
.
Yeah
,
we'll
tell
you
more
about
Relator
and
we'll
also
tell
you
about
the
prefixes
pre
and
We'll
explain
what
all
three
prefixes
mean
and
give
you
lots
of
examples
.
There'll
be
a
quiz
at
the
end
and
a
top
tip
for
learning
vocabulary
.
But
first
,
let's
hear
from
Katie
.
She's
an
environmental
campaigner
.
While
you
listen
,
try
to
answer
this
question
.
What
do
teachers
do
with
cereal
boxes
?
Here's
Katie
.
Most
food
in
supermarkets
nowadays
is
prepacked
in
plastic
and
cardboard
.
This
creates
so
much
waste
.
Takeaways
and
precooked
meals
also
use
a
lot
of
packaging
.
We
have
to
re-educate
people
to
cook
for
themselves
so
they
don't
just
reheat
meals
.
And
people
really
need
to
become
more
proactive
in
recycling
materials
.
Teachers
in
preschool
are
great
at
this
.
They
reuse
cereal
boxes
to
make
fantastic
models
of
robots
and
spaceships
with
the
kids
.
So
we
asked
you
,
what
do
teachers
do
with
cereal
boxes
?
And
the
answer
is
they
reuse
them
to
make
models
of
robots
and
spaceships
.
That's
right
.
They
make
something
new
with
the
boxes
.
But
instead
of
saying
they
use
the
boxes
again
,
Katie
said
the
word
reuse
.
Now
the
prefix
spelled
r
e
in
front
of
a
word
means
again
.
So
re
plus
use
means
use
again
.
We
also
had
re
plus
cycling
,
which
also
means
to
use
again
.
Listen
out
for
more
words
with
in
this
clip
.
We
have
to
re-educate
people
to
cook
for
themselves
so
they
don't
just
reheat
meals
to
use
the
word
re-educate
.
That's
ri
,
which
means
again
educate
.
So
re-educate
means
educate
again
.
And
in
this
case
re-educate
means
teach
people
to
behave
in
a
different
way
so
they
start
to
cook
for
themselves
.
Another
word
with
was
reheat
.
That's
RI
plus
heat
making
reheat
which
means
heat
again
.
Good
.
Let's
have
another
clip
now
,
see
if
you
can
spot
a
different
prefect's
.
Most
food
in
supermarkets
nowadays
is
prepacked
in
plastic
and
cardboard
.
Takeaways
and
pre
cooked
meals
also
use
a
lot
of
packaging
.
We
heard
Prepacked
and
Precooked
both
start
with
pre
spelt
p
r
e
which
means
before
or
already
.
So
a
lot
of
the
food
in
supermarkets
is
already
packed
in
cardboard
and
plastic
.
It's
packed
and
you
can
buy
meals
that
have
been
made
and
cooked
before
you
buy
them
.
Pre
plus
cooked
means
already
cooked
.
And
the
children
Katie
talked
about
were
in
preschool
.
So
that's
pre
plus
school
,
that's
preschool
.
It's
a
place
where
children
go
before
they
go
to
proper
school
.
So
that's
real
and
pre
.
Now
let's
talk
about
pro
spelled
p
r
o
.
Katie
said
people
need
to
be
more
proactive
in
recycling
pro
means
in
support
of
or
in
favor
of
something
.
So
being
proactive
,
pro
plus
active
in
recycling
means
making
more
effort
to
recycle
things
.
Neil
,
are
you
a
proactive
recycler
?
Yeah
,
well
,
we've
got
two
bins
,
one
for
recycling
,
one
for
all
the
food
.
So
I
suppose
I
am
very
good
.
Now
,
another
word
with
the
prefix
pro
that
is
used
a
lot
when
talking
about
food
is
probiotic
.
Probiotics
are
good
bacteria
that
help
to
keep
you
healthy
.
Oh
,
you're
listening
to
BBC
Learning
English
.
And
we're
talking
about
the
prefixes
and
pro
,
I
know
for
a
quiz
,
number
one
,
which
prefix
goes
before
the
word
school
to
make
the
word
for
a
place
for
very
young
children
?
Is
it
A
three
,
B
three
or
C
pro
?
And
the
answer
is
B
pre
.
It's
preschool
.
Good
number
two
.
What
would
you
do
with
a
ready
made
meal
?
Would
you
A
,
pre-heat
it
,
B
reheat
it
or
C
Crozet
it
.
And
the
answer
is
B
that's
reheated
.
Great
.
On
number
three
,
if
you
want
to
improve
your
English
,
should
you
be
A
reactive
,
B
proactive
or
C
proactive
when
you're
learning
new
words
and
the
answer
is
C
it's
pro
.
That's
proactive
and
that's
the
end
of
the
quiz
.
Well
done
.
If
you
got
them
right
.
And
now
here's
today's
top
tip
for
learning
vocabulary
.
Try
to
group
new
words
by
their
prefixes
.
This
will
help
you
to
remember
their
meaning
.
