"This is the program that I am going to take at Uvic unless i
changed my mind." <--why is changed wrong?, why isn't it a "to be" form?
The 'to be'form is a passive- you change your own mind- so it's active and the past tense, which is what it is, doesn't work. It makes no sense to say 'my mind needs to be changed'.
"I will need that published." = 'to be published' <---how is it a "to be" form? Is it like, "I need him killed immediately." ?[/b] Yes.
