Like English, French can express the future in a variety of ways. Both languages have of course the simple future. So: "I'll speak French in Paris during my vacation/Je parlerai français à Paris pendant mes vacances";
"You'll finish your homework tomorrow/Tu finiras tes devoirs demain";
"He'll sell his textbooks at the end of the semester/Il vendra ses manuels à la fin du semestre"; etc.

    But both languages have a whole range of expressions that point to the future without using forms of the simple future. So: "I want to speak French Paris during my vacation/Je veux parler français à Paris pendant mes vacances";
"You hope to finish your homework tomorrow/Tu espères finir tes devoirs demain";
"He intends to sell his textbooks at the end of the semester/Il a l'intention de vendre ses manuels à la fin du semestre"; etc.
