First, orient them towards receiving feedback constructively. You could say, "we should review your work, and here's what I think... please understand that this is feedback about the work and not you" or something on similar lines.
Second, stick to feedback about work. No personal attacks.
Third. Direction. Create an actual path and learning schedule to improve them. Can't type? There are websites. Can't read? Read a book/newspaper everyday. Can't speak? Help them join a club.
This is a pivotal moment not just for the intern, but also for you. The impression they carry will remain etched for years, and will also become your market reputation. Take genuine interest in their growth, and they will help you grow.
