Food

Grammar
and
usage
Lead-in
?
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.

Working
out
the
rule
When
the
to-infinitive
is
used
as
a
subject,
we
usually
use
the
preparatory
subject
at
the
beginning
of
the
sentence.
The
to-infinitive
can
also
be
used
as
a
predicative.
It
usually
comes
after

不定式和动名词作表语都可以用于表示主语“是什么”，但不定式作表语强调的是一次性的、具体的、将要发生的动作；动名词作表语强调的是一般性的，抽象的、经常发生的动作。如比较下面两个句子：
