This exercise is about making past simple questions. It's something you'll use a lot, so I'd suggest you make sure you know it perfectly. This exercise doesn't include 'be' but instead has a variety of other verbs (most of them are quite easy verbs - at the moment it's good to concentrate on grammar, and then think about vocabulary at another time).
