"Am I pretty?"
Why there nothing between pronoun and adjective here? Can we just skip 很 in questions?
Someone could comment on that! I think 很 is not used here because it's a question! Unless you wanted to ask "am I very beautiful" emphasising your preconceived idea of being already "some" beautiful! Is that right?
Does anyone else think that in the matching exercises, the piao(4) sounds more like piao(1)?
Pretty/Cute cross over semantically in English. They should always use "beautiful" here.
Only if you want to say someone is "very pretty/beautiful." 很 isn't entirely necessary. If you're telling someone they're pretty, it's just a nicer way of saying it, though it's fairly colloquial to just always say it
