My french coursework is about technology in young people's lives, and i'm finding it hard to add 5+ tenses. could anyone give me some examples of good tense sentences for anything to do with technology in any tense (just not present, i understand that and that's simple enough to understand to me).

You could say something like "Je pense que ce serait meilleur si les jeunes utiliseraient ses portables moins régulièrement" (I think that it would be better if young people used their phones less regularly) [conditional tense] or "A l'avenir j'espère que les jeunes vont aller à l'extérieur plus" (In the future I hope that young people go outside more) [present and then future] or something about in the past, there not being technology so.. and then expand on the differences? you could say "Quand on était petit" [imperfect tense- past] (when one was younger) to do this, hope this helps :)
