Notes for teachers

Use Part 1 as a warm-up on pronoun choice, Part 2 to check punctuation, meaning and when 'that' or omission is possible, and Part 3 to test relative clauses in a connected text. The test targets frequent B2 errors: using 'that' in non-defining clauses, adding an extra pronoun ('where we stayed it was'), confusing 'whose' and 'who's', and using 'that' or 'what' to refer to a whole clause. As a follow-up, ask students to rewrite pairs of short sentences as one sentence with a relative clause and to explain whether commas are needed.
