Question

是can't wait to do sth.还是can't wait doing sth

Answer 1

是can't
wait
to
do
sth，没有can't
wait
doing
sth这种用法。
can't
wait
to
do
sth表示的是等不及做某事，迫不及待做某事。
类似can't
wait
doing
sth用法的只有can't
help
doing
sth，该句式表示的意思是情不自禁做某事，不可避免做某事。
例句：
1.
He
can't
wait
to
put
on
his
new
shoes.他迫不及待地穿上新鞋子。
2.
We
couldn't
wait
to
go
home.我们迫不及待地回家。
3.
They
can't
wait
to
see
the
new
manager.他们迫不及待地见到新经理。
4.
She
can't
wait
to
see
her
child.她迫不及待地见到孩子。
5.
The
old
man
can't
wait
to
build
a
new
house.这位老人迫不及待地建一座新房子。

Answer 2

两个都对，但意思上有小小区别：
can't
wait
to
do
sth
-
more
importance
for
'
to
do
'
（重点在“to
do
-
做”上）
can't
wait
doing
sth
-
more
importance
for
'
sth
'
（重点在“sth
-
事情”上）
如：
I
can't
wait
to
see
you
(重点在“见面”上）
I
can't
wait
getting
marry
(重点在“结婚”这件事上）
