Speaking
TIP
Continuing
a
discussion
To
ensure
a
discussion
moves
smoothly,
everyone
should
be
active.
When
answering
questions,
you
should
follow
your
answers
with
explanations
or
personal
experiences.
If
you
have
any
doubts,
ask
questions
to
check
your
understanding
and
to
get
further
information.
A:
Do
you
think
materials
physics
would
be
a
great
theme
for
the
school
Science
Festival?
B:
I’m
not
sure.
Do
you
mean
the
study
of
how
new
materials
are
made
for
modern
use
like
in
technology?
A:
Exactly!
Smartphone
touchscreens
and
fibre
optics
are
some
common
new
materials.
B:
Yes,
I
learnt
about
chemically
strengthened
glass
from
a
documentary
too.
Do
you
think
Professor
Wang
will
agree
to
give
a
lecture
about
it?
I
know
his
knowledge
about
materials
physics
is
excellent.
A:
If
we
invite
him
soon,
I’m
sure
he
will!
We
should
book
the
school
hall.
B:
OK.
I’ll
make
an
appointment
with
Professor
Wang
and
find
out
the
availability
of
our
school
hall
for
Monday
morning.
A:
Great!
For
the
Science
Workshop
on
Tuesday,
students
can
make
their
own
materials.
We’ll
provide
what
they’ll
need
with
the
necessary
equipment.
B:
It
will
be
fun.
They’ll
find
out
what
new
material
they
can
make,
the
features
it
has
and
how
it
can
be
used.
What
activities
do
you
suggest
for
the
Science
Fair
on
Wednesday?
A:
The
students
could
demonstrate
how
their
materials
can
be
used
to
change
people’s
daily
lives.
They
can
also
display
their
new
materials
as
decorations!
B:
I
like
that
idea.
Let’s
get
started!
D
Write
a
plan
for
the
school
Science
Festival.
Use
your
ideas
from
part
C
and
the
information
in
parts
A
and
B
to
help
you.
Planning
your
writing
Learning
about
the
text
type
A
plan
is
a
detailed
proposal
for
doing
something.
It
can
offer
the
reader
a
better
understanding
of
a
certain
project
or
activity.
Learning
about
the
structure
A
plan
involves
both
the
theme
and
events.
Organize
the
Science
Festival
events
clearly,
usually
in
order
of
time.
Describe
one
event
in
one
paragraph.
