Hi
.
Could
you
give
me
some
information
on
your
Russian
courses
?
B
.
Yeah
,
sure
.
Take
a
seat
.
What
would
you
like
to
know
?
A
.
Well
,
what
____________________
a
typical
class
____________________
?
(
involve
)
B
.
Well
,
it
varies
,
but
there
is
always
a
range
of
activities
,
with
lots
of
speaking
practice
.
A
.
So
how
many
students
____________________
there
in
a
class
?
(
be
)
B
.
A
maximum
of
12
.
A
.
And
where
____________________
they
____________________
____________________
?
(
come
from
)
B
.
All
over
the
world
.
We
have
about
30
different
nationalities
at
any
one
time
.
A
.
And
how
long
____________________
each
class
____________________
?
(
last
)
B
.
About
50
minutes
,
longer
if
it's
an
intensive
course
.
A
.
How
____________________
you
____________________
one
student's
level
?
(
decide
)
B
.
Apart
from
beginners
,
there's
a
written
test
and
also
an
oral
~
so
that
we
know
how
good
you
are
at
speaking
and
understanding
.
A
.
What
qualifications
____________________
the
teachers
____________________
(
have
)
,
if
you
don't
mind
me
asking
?
B
.
No
,
it's
a
good
question
.
All
our
teachers
are
native
speakers
and
most
of
them
have
lots
of
experience
.
A
.
OK
,
fair
enough
.
I've
used
quite
a
few
books
already
so
which
ones
____________________
you
____________________
____________________
____________________
(
go
/
use
)
in
the
next
course
?
B
.
Well
,
It
depends
on
the
class
.
In
intensive
courses
we
use
a
wide
range
of
different
materials
,
some
of
them
we
develop
ourselves
.
A
.
One
last
question
.
How
much
____________________
the
course
____________________
(
cost
)
?
