This storyboard provides a chance to elicit a situation with no internal temporal structure (e.g. leave for work), a situation reported as a single whole, but with internal temporal structure (e.g reading a book the whole afternoon) and a progressive situation (reading a book). Based on Comrie’s (1976) definition of perfective and imperfective aspects, the first situation is imperfective, the second one a combination of perfective and imperfective (or aorist), and the third one imperfective. The goal is to observe what strategies the language you’re working with will use to communicate those meanings. Enjoy!
