英语表达 用做插入语 “我的意思是”除了I mean还有什么

that is to say

in my view
i believe that
from my point of view
i was saying that
it was
i think
i refer that is

that is或者that is to say.

i think

I was saying that.....和I mean一个意思，不过好长

that is to say
in my opinion
i believe that
from my point of view

i refer to...
