Notes for teachers
Use Part 1 as a warm-up on common verb patterns, then move on to Part 2 for prepositions, purpose and negatives, and Part 3 for meaning changes and error spotting. The test targets typical B1 mistakes such as 'suggest to do', 'for to buy', 'looking forward to see' and 'promise doing'. As a follow-up, ask students to sort the verbs into '-ing', 'to-infinitive' and 'both' lists and write their own sentences with each pattern.
