2. Grammar: Modals of Advice, Obligation, and Necessity
- Advice (Conseil):
- $Subject + should / shouldn't + Verb (infinitive)$
- Example: You should eat more fruit. / You shouldn't sleep late.
- Obligation (Obligation forte):
- $Subject + must + Verb (infinitive)$ (Internal obligation/rule).
- $Subject + have \ to + Verb (infinitive)$ (External obligation/law).
- Example: You must see a doctor immediately.
- Prohibition (Interdiction):
- $Subject + mustn't + Verb (infinitive)$
- Example: You mustn't smoke in hospitals.
- Lack of necessity (Absence d'obligation):
- $Subject + don't \text{ / } doesn't \text{ have to} + Verb (infinitive)$
- Example: You don't have to go to the hospital if you feel better.
Méthodes à maîtriser
- Donner un conseil (Giving advice):
- Utilise toujours la structure : $Should + Verb$.
- Si tu veux être plus formel, utilise : $It \text{ is advisable to } + Verb$.
- Exprimer le but (Expressing purpose):
- Pour expliquer pourquoi on fait quelque chose pour la santé : $to + Verb$ ou $in \text{ order to } + Verb$.
- Example: We exercise $in \text{ order to } stay \text{ fit}$.
- Différencier l'interdiction de l'absence d'obligation :
- $Mustn't$ = C'est interdit (danger/règle).
- $Don't \text{ have to}$ = Ce n'est pas nécessaire, mais tu peux le faire si tu veux.
