Lead-in
T
shows
Ss
some
pictures
and
sentences
to
arouse
their
interest.
T:
Hello,
everyone.
I
would
like
to
show
you
some
pictures
and
sentences.
These
delicious
food
are
irresistible
to
me.
And
they
are
always
enough
to
lift
my
spirits.
?
As
a
real
foodie,
I
enjoy
all
kinds
of
foods.
My
dream
is
to
try
different
restaurants
and
taste
various
foods.
?
Yesterday
I
invited
some
friends
to
try
a
great
new
restaurant
for
dinner.
?
We
arrived
at
the
restaurant,
only
to
see
a
huge
line
of
people
waiting
to
get
into
the
restaurant.
?
Nothing
can
stop
our
determination
to
have
a
try.
We
decided
to
wait
outside.
?
After
an
hour
of
waiting,
we
were
invited
to
go
into
the
restaurant
and
take
the
order.
?
The
dishes
are
extremely
delicious.
It
is
worthwhile
to
have
such
a
long
wait.
T:
From
these
sentences,
we
could
see
to-infinitives
used
as
different
sentence
elements.
Today,
we
will
explore
the
rules
concerning
to-infinitives
as
subjects
and
predicatives.
【设计意图：学生初中已经接触过不定式，在必修三第二单元又已经学了动词不定式的作定语和状语的用法，所以教师根据本单元的话题，创设语境，编写含有动词不定式用作不同成分的句子，感知不定式的各种用法。让学生感受新情境，复习旧知识，体验新内容。】

Exploring
the
rules
concerning
to-infinitives
as
subjects
and
predicatives
1.
T
asks
Ss
to
find
out
to-infinitives
as
subjects
in
the
blog
entry.
T:
Some
foodies
prefer
to
eat
out
while
others
would
rather
eat
at
home.
Below
is
a
blog
entry
about
eating
out
and
eating
at
home.
Find
the
sentences
that
use
to-infinitives
as
subjects.
The
first
one
has
been
done
for
you.
Example:
To
eat
out
was
also
a
social
activity,
...
2.
T
asks
Ss
to
compare
and
work
out
the
rule
according
to
the
above
two
sentences.
?
When
the
to-infinitive
is
used
as
a
subject,
we
usually
use
the
preparatory
subject
it
at
the
beginning
of
the
sentence.
3.
T
asks
Ss
to
find
out
to-infinitives
as
predicatives
in
the
blog
entry.
T:
Now
look
at
this
example.
My
first
thought
at
mealtimes
was
to
eat
at
a
restaurant.
In
this
sentence,
What
element
is
to-infinitive
used
as?
Can
you
find
other
sentences
with
to-infinitives
as
predicatives
in
this
blog
entry?
4.
T
asks
Ss
to
compare
and
work
out
the
rule
according
to
the
above
two
sentences.
?
The
to-infinitive
can
also
be
used
as
a
predicative.
It
usually
comes
after
the
verb
be.
5.
T
asks
Ss
to
complete
the
following
sentences.
?
被邀请到你家做客真的是太荣幸了。
It
is
a
great
honour
to
be
invited
to
your
family.
?
在家做饭准备环节需要花很长时间。
It
takes
a
long
time
to
prepare
for
home-cooked
meals.
?
你为我们做了这么多美味的菜真的是太好了。
It
is
nice
of
you
to
make
so
many
tasty
dishes
for
us.
?
在当今社会，我们学会做饭还是很有用的。
It
is
useful
for
us
to
learn
how
to
cook.
?
然而，烹饪对于我来说还有点挑战性。
However,
cooking
seems
to
be
challenging
for
me.
?
是否我能学会做几个菜，以后见分晓。
It
remains
to
be
seen
if
I
can
cook
a
couple
of
dishes.
6.
T
guides
Ss
to
summarize
the
rules
of
to-infinitives
used
as
subjects
and
predicatives.
【设计意图：通过本环节，学生认知了不定式做主语时往往用it作形式主语。不定式做表语时表示具体动作或者将来的动作。通过设计与本单元话题相关的句子翻译，更好地让学生了解相应的一些句式还有不定式的被动式，为后续的教学环节做好铺垫。】
