Teacher's notes
- Timing: Tasks 1 to 4 take about 25 minutes; Task 5 about 10, or set it as homework.
- The one to watch: will after if. It is the most persistent mistake in the whole B1 syllabus, and it appears in Tasks 1, 3 and 5. One rule on the board beats twenty corrections.
- If I were or if I was: were is the form expected in exams and in writing, and was is very common in speech. Teach were, and do not mark was wrong when a learner says it aloud.
- Task 3 is the thinking task. Learners who can do Tasks 1 and 2 but not Task 3 have the forms without the meaning, which is exactly what to spend the next lesson on.
- Extension: learners write three dilemmas of their own and swap them with a partner, who answers each with one conditional sentence.
