In this lesson, Amélie will tell us about 'les Vélib' (vélos libres), an initiative in the French capital which puts bicycles at the disposal of those looking for a healthier option for getting around. We'll learn new expressions including 'Ça marche du tonnerre!' and 'prendre un abonnement'. We'll study some verbs, too, including 'assombrir', 'se réjouir de' and 'mettre en place'.
