have a good time 接to do 还是doing 为什么

是跟doing
估计是你记错了，语法上，只要是很开心做某事，都是跟doing,比如
enjoy
oneself
doing,have
fun
doing
这里的have
,并不是单纯的有，这个行为动词，而是表达的很开心做某事，因此用doing
如果have
是表达有，这个行为动词，则是to
do
比如，i
have
ten
minuites
to
remember
the
words
如果have
是使役动词，则不能用to
要具体情况具体分析

传统的用法为
It's
a
waste
of
time
doing
sth
It
is
a
waste
of
time
going
to
the
doctor
with
most
mild
complaints.
一点小毛病就去看医生是浪费时间。
