教材分析
This
teaching
period
mainly
deals
with
the
grammar：the
subjunctive
mood.In
the
English
language
verbs
are
often
divided
into
three
different
moods—the
indicative
mood，the
imperative
mood
and
the
subjunctive
mood.The
indicative
mood
is
used
to
indicate
a
fact
or
put
forward
a
viewpoint.The
imperative
mood
is
used
to
express
direct
commands
or
requests.It
tells
you
to
do
something.It
is
used
to
signal
a
prohibition，permission
or
any
other
kind
of
exhortation.The
subjunctive
mood
is
used
to
express
a
condition
which
is
doubtful
or
not
factual.It
is
most
often
found
in
a
clause
beginning
with
the
word
“if”．It
is
also
found
in
noun
clauses，following
a
verb
that
expresses
a
doubt，a
wish，regret，request，demand，or
proposal.The
following
are
verbs
typically
followed
by
clauses
with
the
subjunctive
mood：ask，demand，determine，insist，move，order，prefer，recommend，regret，request，require，suggest，wish.In
this
period
we
will
focus
on
only
part
of
the
usages
of
the
subjunctive
mood，that
is，the
subjunctive
mood
beginning
with
the
word
“if”
and
that
following
the
verb
“wish”．
