I have too much to do here. ["too" = very]
I have to do here too much. ["too" = more than "I want"]
As I understand it, these sentences have the different meaning. The first sentence says that there is a lot of work to do. The second sentence says that "I must do" more than "I want". Right?
The above mentioned means also that if there is a word (or some words) between "have" & "to do", we can't consider it as "have to do" + that word (or those words). Am I right?
