(3)动名词的复合结构作主语。当动名词有自己的逻辑主语时,
常可以在前面加上一个名词或代词的所有格作动名词的逻辑主语,
构成动名词的复合结构。

　　Recently,
our
class
had
a
heated
discussion
about
whether
we
need
space
exploration.
There
are
a
majority
of
students
who
believe
that
space
exploration
has
more
advantages.
Many
new
products,
such
as
weather
and
communication
satellites,
are
products
of
space
programs,
and
they
have
benefited
people
all
over
the
world.
However,
others
think
that
it
is
a
waste
of
time
and
money
to
explore
space.
They
point
out
the
fact
that
it
has
cost
billions
of
dollars
to
carry
out
the
space
research,
but
there
have
been
many
mysteries
with
little
information
brought
back.
Every
coin
has
two
sides.
In
my
opinion,
though
space
exploration
is
a
challenge
to
human
beings,
it
is
worth
it.
