一、美文背诵
On?line
voting
becomes
increasingly
popular,
and
many
competitions
get
people
involved
in
it.
It
is
beneficial
to
some
people,
while
it
puts
others
into
a
dilemma
over
whether
to
vote
or
not.
It
makes
no
difference
from
ordinary
voting
events,
in
which
candidates
go
around
to
seek
supports.
In
addition,
the
Internet
makes
surveying
and
voting
easy
and
convenient,
regardless
of
time
and
space.
Furthermore,
voting
on
the
Internet
makes
instant
feedback
possible.
To
be
honest,
voters
sometimes
feel
annoyed,
not
because
they
hate
voting,
but
because
they
are
divided
between
emotion
and
fairness.
Things
will
turn
better
if
we
can
work
out
some
participation
rules
for
people
to
obey.
Therefore,
I
hold
a
positive
attitude
towards
on?line
voting.
