3.11. Grammar. Modal verbs for advice and recommendations.
What are the modal verbs for advice? (Positive and negative.) Should / Shouldn’t which mean exactly the same as ought to/ oughtn’t to.
What are their past forms? Their past forms, as already mentioned follow the same structure as past modal verbs for deduction. MODAL + HAVE + PAST PARTICIPLE Another very useful and common way of expressing advice is with the structure had better... which is usually contracted ‘You’d better listen to me.’ What is the negative form? A good question. Had better not... Notice that this expresses advice in the present and although it has a ‘past’ word, cannot be used in the past.
