Notion Myths and Heroes

Sujet du devoir

Salut tout le monde, je dois faire une notion d'anglais pour Vendredi j'ai commencé mais j'ai besoin d'aide pour la suite, là voici: 

I am going to talk about the notion of myths and heroes.

"First of all, I would like to give a quick definition of that notion. Briefly, a myth can be defined as a story about gods or heroes, it can be a popular belief or a tradition or a false notion. Then, a hero is a person who is admired for their courage, outstanding achievements, or noble qualities. It can be the main character in a book or a film or a person with superhuman qualities. It can also be a modern-day hero or a person who has performed a heroic act . Examples can be: a patriotic or national hero like human rights defender, a fictitious hero (superhero or film star), a defender of common values, unknown heroes like a firemen and then our own personal hero like a member of our family . With this notion we may wonder if the fictif and real heroes have an impact in our society? " 

Je voulais faire comme plan 

I- Les superheroes ont impact dans nos sociétés mais moins qu'avant

II- Mais ils continuent d'inspirer les héros d'aujourd'hui 

Est ce que cela marche comme plan ou non ?
