📘 Fiche de cours

L'essentiel du cours

Le développement durable (Sustainable Development) est défini comme un développement qui répond aux besoins du présent sans compromettre la capacité des générations futures à répondre aux leurs. Il repose sur trois piliers :

  1. Economic growth : Créer de la richesse tout en gérant les ressources.
  2. Social inclusion : Équité, éducation et santé pour tous.
  3. Environmental protection : Préservation des écosystèmes et lutte contre le changement climatique. Vocabulaire clé : Renewable energy (énergie renouvelable), Carbon footprint (empreinte carbone), Biodiversity, Recycling, Eco-friendly.

Méthodes à maîtriser

  • Argumentation : Savoir structurer un paragraphe (Topic sentence + Supporting details + Concluding sentence).
  • Utilisation des connecteurs logiques : Therefore, consequently, however, in addition, for instance.
  • Rédaction d'un article ou d'un essai : Respecter la structure : Introduction (définition du problème), Body paragraphs (arguments), Conclusion (recommandations).

Exemples corrigés

Exemple de phrase argumentative : "Using solar energy is crucial because it reduces our reliance on fossil fuels and lowers greenhouse gas emissions." Analyse : Sujet (Solar energy) + Connecteur (because) + Effet (reduces reliance/lowers emissions).

Erreurs fréquentes

  • Confondre Sustainable (durable) avec Sustained (soutenu).
  • Oublier de mentionner les trois piliers dans un essai complet.
  • Utiliser un registre trop familier dans un essai formel (ex: utiliser "gonna" au lieu de "going to").
