Anohito san, in addition to the excellent ideas already given, your example of "I will be the one to go to the market place for..." sounds quite formal and rather old-fashioned in its complexity. It's something my Grandma would have said, if we had all discussed who would go, and finally she made a decision. (She prided herself on her 'correct English' bless her
)
This might be because the English language teaching in the Philippines hasn't quite caught up with the present-day variety spoken in native countries; one reason might be that they're still using very old English textbooks over there.
It could also be the same as a foreigner who's learnt formal Japanese, and is greeted with looks of utter surprise over there at his or her speech. The opposite situation: a few of my Japanese friends try to use 'whom' in their written English, when a native speaker wouldn't anymore.
