MODAL VERBS FOR RULES PPT PRESENTATION FOR EFL STUDENTS

Modal verbs for rules

1. MODAL VERBS FOR RULES To talk about rules, we use the modal verbs must , have to and can

2. To say that something is obligatory, we use must or have to. You have to train hard to run a marathon Runners must arrive twenty minutes before the race.

3. To say that something is allowed, we use can. Members can use the swimming pool for free.

4. To say that something is not obligatory, we use don´t have to. You don´t have to be fit to join the club.

5. To say that something is not allowed, we use cant´s or must not. You can´t touch the ball with your hands or arms in soccer. You must not leave any bags in this area.

6. The modal verbs must and have to , and can´t and must not , have very similar meanings. In general, we prefer to use have to and can´t in spoken English to talk about rules. In informal written English, we prefer to use must and must not. You have to pay $40 to be in the race . ( spoken ) Competitors must pay $40 to enter the race . (formal, written ) You can´t go near the pool with shoes on . ( spoken ) Customers must not go near the pool with shoes on . (formal, written ) But remember tha must not and don’t have to have completely different meanings – mustn’t means “ don’t do it !” while don’t have to means “ it’s not necessary to do it .”

7. Form : We normally use modal verbs before a main verb . You can borrow my running shoes . The modal verbs must / must not and can / can’t don’t work like normal verbs . They never change – we use the same form for all persons (I, you , he/ she / it , etc.). We don’t use do, does , or did to make questions or negatives.
