This
is
the
third
period
of
this
unit.
The
emphasis
of
this
period
will
be
placed
on
the
grammar
of
this
unit.
The
key
grammatical
structure
in
this
unit
is
the
predicate
clause.
A
predicative
clause
is
a
clause
that
acts
as
a
predicate
in
a
subject-subordinate
compound
sentence.
Like
object
clause
and
subject
clause,
the
predicative
clause
is
also
one
of
the
nominal
clauses.
.In
order
to
make
students
understand
these
points,
teacher
can
first
get
students
to
study
the
usages
themselves
and
try
to
make
a
summary
according
to
the
examples,
and
then
try
to
put
them
into
use
to
improve
the
ability
to
use
them
in
real
situations.
