The
subjunctive occurs mainly in very formal styles, involving the base form of the verb, without any inflections (like the
'-s' on third person singular):
I insist that she do that herself.
The
subjunctive form of the verb
be may occur as the base form
be or as hypothetical
were (for all persons):
Far be it from me to tell you what to do.
If I were a teacher I would be really happy.
However, in your sentences I cannot see any reason for using the
subjunctive mood, I'm afraid.
