Level B2 (approx. band 5.5-6.5) · Academic and General Training When you are not completely sure, English gives you a scale of certainty. Many learners use "maybe" for everything, or they build the forms wrongly: "He must be stayed at home", "That mustn't be true". Speaking Part 3 asks you to predict and explain causes, and Task 2 asks about consequences. In this episode: • Present deduction: must, might, can't • Past deduction: must have, might have, can't have • Likely, unlikely and other ways to predict • Speculation in part 3 and task 2 • Listening lab • Language bridge • Practice • Self-check questions with answers Key points: • must for a strong yes, might, may or could for possible, and can't for a strong no. • use modal plus have plus past participle for guesses about the past; write have, never of. • likely to, probably and may let you predict with the right level of certainty. • in Part 3 and Task 2, match the modal to your real level of certainty.
