Question

look forward to 与 looking forward to有什么区别

Answer 1

两者其实区别不大,你如果一定要鸡蛋里挑骨头,则有这样的解释：
1、从语气上来说,-ing
形式比较personal
和friendly,和
look
forward
to...相比较少为正式,如果你要表示礼貌而有亲和力则用looking
forward
to...,look
forward
to在非常正式严谨的business场合比较适用.
2、国外英语论坛上native
speaker给的解释二：
“The
difference
is
how
the
speaker
perceives
their
own
words:
an
action
seen
as
a
whole/accomplished
(I
look
forward...)
or
continuing
(I
am
looking...).
一个动作的结束（look
forward
to...）和一个动作的持续（looking
forward
to...）
Unless
very
self-aware
or
possibly
an
English
teacher,an
ordinary
native
speaker
will
be
unable
to
explain
their
choice
between
the
two
and
so
the
difference
between
a
mental
impression
(I
look
forward)
and
a
mental
activity
(I'm
looking
forward).In
such
cases,attempting
to
explain
these
subtleties
to
your
students
may
prove
counterproductive,unless
of
course
they're
advanced
enough
to
handle
it.It
is
my
policy,that
until
then
they're
perfectly
fine
knowing
there
is
no
real
difference
there.”

Answer 2

look
forward
to
doing
sth./be
looking
forward
to
doing
sth.
意思相同，只不过进行式更强调“此时此刻”的心情。
